N-acylated benzyl carbamate with 86% yield was achieved in 20 min

N-acylated benzyl carbamate with 86% yield was achieved in 20 min of time. Then we examined the reaction conditions in presence of anhydrous cerium Chloride with the same substrates, observed that the reaction learn more was completed within 6 min of time with 95% yield ( Scheme. 2, Entry-1 in Table 2) and decided to go with anhydrous cerium chloride to explore the substrate scope in this case as well. These reaction conditions were success

full while exploring the possibilities with structurally diversed acid anhydrides like propionic, pivalic and benzoic anhydrides. We have examined the same reaction conditions to find out the applicability in case of secondary carbamates like amino acid carbamates and amine carbamates and found positive results. All the results regarding the N-acylation of carbamates were mentioned in Table 2. Synthesized compounds were screened check details for their antifungal activity by anti Malassezia in vitro liquid broth culture in high-throughput assay format for anti-dandruff activity testing against two virulent organisms M. furfur and M. pachydermatis MF-ATCC44338 MP-ATCC42757 were the corresponding strains. The compounds were tested in four replicates in the concentration range of 200 uM, 180 uM, 160 uM, 140 uM, 120 uM, 100 uM, 75 uM, 50 uM,

25 uM, 10 uM and 1 uM by incubating them for stipulated time period of 72 h and taking their growth observations in the form of optical density at 600 nm wavelength at different time intervals. The growth in the treated wells was compared with the growth in the untreated wells. Ketoconazole was used as control, among heptaminol the compounds

screened 2a, 2i and 4a showed activity than the standard antifungal drug i.e. Ketoconazole, corresponding results were mentioned in Table 3. We have developed a novel and efficient method for of N-acylation of sulfonamides and carbamates with carboxylic acid anhydrides under solvent free and mild reaction conditions in presence of cerium (III) chloride. Synthesized compounds were evaluated for their antifungal activity against M. furfur and M. pachydermatis. Three compounds 2a, 2i, and 4a showed very good activity against both the organisms, for the first time N-acyl sulfonamides and carbamates class was evaluated as potential anti-Malassezia agents. This outcome indicates that there is a good scope for evaluation of this class of compounds as potential leads towards anti Malassezia activity. All authors have none to declare. “
“Tissue engineering is very fast growing scientific area in this era and used to create, repair, and/or replace cells, tissues and organs by using cell and/or combinations of cells with biomaterials and/or biologically active molecules and helps to produce materials which very much resembles to body’s native tissue/tissues. Tissue engineering is the connecting discipline between engineering materials science, medicine and biology.

, 2006). Similarly, a primate study showed that fluoxetine treatment prevented the onset of depression-like this website behaviours and increased the number of newly-born neurons that were at the threshold of maturation within a specific region of the dentate gyrus (anterior region), thus leading to the suggestion that adult hippocampal neurogenesis may contribute to the recovery promoted by

fluoxetine (Perera et al., 2011). On the other hand the antidepressant-like effects of non-monoaminergic based antidepressant-like drugs, such as CRH1 or V1b antagonists, are not affected by inhibition of adult hippocampal neurogenesis (Surget et al., 2011 and Bessa et al., 2009) which is in contrast to many findings with antidepressants that target the monoaminergic system such as fluoxetine and imipramine (Surget et al., 2011, Perera et al., 2011 and Santarelli et al., 2003). Thus, it has been suggested that antidepressant drugs increase adult hippocampal neurogenesis,

independently of their behavioural effects and that antidepressant-induced increases in adult hippocampal neurogenesis might not be the final process in the recovery from stress-induced depressive-like behaviour BMS-354825 purchase (Bessa et al., 2009). The hippocampus can be divided along its septotemporal axis into dorsal and ventral regions in rodents and into anterior and posterior regions in primates, based on their distinct afferent and efferent connections (Fanselow and Dong, 2010). Lesion, optogenetic and electrophysiological studies in rodents suggest that this anatomical segregation results in a dichotomy in the Adenylyl cyclase function of the dorsal hippocampus (dHi) and the ventral hippocampus (vHi) (Fanselow and Dong, 2010 and Bannerman et al., 2004). While the dHi (analogous to the posterior hippocampus in primates) seems to play a preferential role in spatial learning and memory processes, the vHi (analogous to the anterior hippocampus in primates) preferentially regulates anxiety and the response to stress (Fanselow and Dong, 2010, Bannerman et al., 2004 and Moser and Moser, 1998). Since adult hippocampal

neurogenesis has been implicated in processes preferentially regulated by the dHi (spatial learning and memory) and the vHi (stress response), it is possible that adult neurogenesis might be regulated preferentially in the dHi or the vHi, depending upon the stimulus (Tanti and Belzung, 2013 and O’Leary and Cryan, 2014). Indeed, several studies have reported that stress affects several stages of adult neurogenesis, preferentially in the vHi rather than the dHi (Tanti and Belzung, 2013 and O’Leary and Cryan, 2014). Some (but not all) studies also report that antidepressant-induced increases in cytogenesis and neurogenesis occur preferentially in the vHi but not dHi (Tanti et al., 2012, Jayatissa et al., 2006, O’Leary et al., 2012, O’Leary and Cryan, 2014 and Banasr et al., 2006).

In special circumstances like the DPT-hepatitis B-Hib vaccine issue, the ACCD requests

external technical assistance to inform recommendations. WHO, for instance, was invited to carry out an independent assessment of causality in the DPT-hepatitis B-Hib and rubella vaccine incidents. The WHO assessment provided an unbiased, second opinion for the Committee to consider. The Committee discussed the findings from both the Expert Committee on AEFI and the WHO assessments – both of which found no conclusive evidence that the DPT-hepatitis B-Hib vaccine caused the deaths – before recommending that the NPI reintroduce the vaccine. Though the decision was not unanimous, the discussions that took place between the Expert Committee on AEFI and WHO further strengthened the capacity of the ACCD to arrive at practical, evidence-based conclusions regarding the future course of action for this vaccine. A similar process was used to respond to the rubella incident, check details which helped the ACCD to counter the widely held belief among the public

and health worker trade unions that it was not anaphylaxis but the inferior quality of the vaccine that caused the death of the child. The ACCD can also recommend health system improvements that will help ensure the success of immunization and other disease control measures. As demonstrated during the DPT-hepatitis B-Hib incident, one selleck screening library drawback in investigating deaths among vaccine recipients in Sri Lanka was the absence of a definitive cause of death, even for deaths in which post mortems had been performed. This was attributed to the fact that Judicial Medical Officers (JMOs), forensic experts who perform autopsies and determine cause of death in homicide cases, conducted these post mortems, but had not been trained to look for pathological causes. The ACCD was able to rectify this by mandating that consultant JMOs use a standardized autopsy protocol when conducting post mortem examinations of all deaths suspected to be immunization-related. A summary of the data required and questions to be answered before the ACCD makes a recommendation about a new vaccine is shown in Fig. 2. To second formulate policy recommendations regarding the

introduction of new vaccines, the ACCD requests a set of data from the Epidemiology Unit. The Unit then appoints a working group, consisting of experts from Ministry of Health agencies, major hospitals, universities and the private sector, to help gather and analyze relevant data concerning the disease and vaccine in question. The Epidemiology Unit may also request technical or financial support from international partners for the collection or analysis of data, in the form of, for instance, an expert, such as a health economist, financing to conduct a local clinical trial, or laboratory training for surveillance studies. The compilation of data on the burden of the disease in question in Sri Lanka is a necessity before the ACCD can approve the introduction of any new vaccine.

HPLC data acquisition and processing

HPLC data acquisition and processing IOX1 was performed by Shimadzu LC Solutions Ver 1.23 SP 1 software. PZA belongs to the basic class of drugs due to its amide functional group. Therefore adjusting the pH of mobile phase to the acidic side ionizes the PZA present in plasma thereby leading to poor recovery. In order to extract the un-ionized form of the drug, it is imperative to adjust the pH to the alkaline side, however, alkaline mobile phase characteristics causes deterioration of the bonded phase in the column due to alkaline hydrolysis of end-capped silica. Compared to acid catalyzed hydrolysis, the hydrolysis of end-capped

silica in alkaline conditions is usually very rapid. Therefore experiments were performed using potassium dihydrogen phosphate in a limited range of pH 7.0–8.0. The response was checked at the detector using a connector (without the column). A pH value of 7.4 ± 0.1 gave maximum Selleck ABT-199 response for the analyte at 268 nm. The run time of analysis was higher when a longer reverse phase column (250 × 4.6 mm i.d,) was used. The resolution

between the peaks was decreased and peaks were not of acceptable peak shape when the experiment was performed using a shorter column (50 × 4.6 mm i.d,). However better resolution, less tailing and high theoretical plates were obtained with Phenomenex column C18 150 × 4.6 cm 5 μm column. The mobile consists of 15:85 v/v methanol and 10 mM potassium dihydrogen phosphate (pH 7.4). The flow rate of the method was 1.0 ml/min. The column temperature was maintained at 25 °C. At the reported flow rate peak shape was excellent,

however, increasing or decreasing the Astemizole flow rate increased the tailing factor and resulted in poor peak shape and in decreased resolution between the drug and internal standard. There was no interference in the drug and the internal standard, from the extracted blank. The peak shape and symmetry were found to be good when the mobile phase composition of 15:85 v/v was used with better resolution of the drug and internal standard. Increasing the organic portion of the mobile phase caused PZA to elute with high tailing and also merging of the peaks for PZA and MTZ. A mobile phase containing aqueous portion greater than 85% led to very late elution and very poor peak shape for MTZ. The peaks were also broad and had unacceptable asymmetry factor. Extraction methods were initially attempted using protein precipitation technique. Organic solvents such as acetonitrile and/or methanol were used as reagents for protein precipitation.13 Initial experiments of protein precipitation were done using 1:3 ratio of plasma:organic solvents. The recovery of the PZA was poor while that of the internal standard was relatively unchanged as compared with liquid–liquid extraction. Since the noise effects in solid phase extraction (SPE) method are similar to that of liquid–liquid extraction, the final analysis was carried out using liquid–liquid extraction (LLE).

In all these studies, no significant difference was observed in t

In all these studies, no significant difference was observed in the anti-poliovirus types 1, 2, and 3 antibody sero-protection rates between the cohorts receiving rotavirus vaccine or placebo at 1 month after the third OPV dose. Because these studies have clearly identified that rotavirus vaccines do not affect the protective immune response to OPV, it has led to the assurance that rotavirus vaccination will not interfere with the goal of polio eradication globally [4] and [32]. Here, we review available data for the effect of trivalent

OPV on the performance of RotaTeq® and Rotarix™. These data should help scientists and public health officials better understand data on the safety and efficacy of rotavirus vaccines that are emerging Bcl-2 inhibitor from various settings worldwide. The effect of OPV MK-2206 price on Rotarix™ immune response has been evaluated in 3 settings: South Africa, Bangladesh, and Latin America (Fig. 1). The three measures of immune responses that were considered in these studies included serum anti-rotavirus IgA geometric mean concentrations (GMC); percentage seroconversion (i.e., anti-rotavirus IgA antibody concentrations > 20 U/mL); or percentage of subjects with detectable rotavirus antigen in stool samples obtained at either days 0, 4, or 7 after rotavirus vaccination (Table 1). For both RotaTeq® and Rotarix™, serum concentrations of antirotavirus IgA antibodies were measured

using similar assays designed by Dr. R.L. Ward [33] and [34]. Data were obtained from either Ketanserin published studies and abstracts or the detailed reports of these corresponding studies available from the GlaxoSmithKline clinical trials Web site [35]. Due to the small sample size of these studies, all

confidence limits overlapped but the general trend of reduced immune response to Rotarix™ when given with OPV was observed in all studies (Fig. 1). South Africa [26], [31] and [35]: In these trials, immunogenicity to Rotarix™ was evaluated with concomitant administration of either OPV or inactivated polio vaccine (IPV), in various dosing regimens and with different vaccine virus concentrations [26] and [31]. In the first study, two different age schedules of vaccination were evaluated – two doses of RIX4414 (a Rotarix™ precursor with titer of 105.2 FFU/mL) were given with OPV or with IPV at either 6 or 10 weeks of or at 10 and 14 weeks of age [26]. The study was not designed for an analysis to assess differences in immune response between the 2 age schedules, which occurred serendipitously as described elsewhere [26]. However, in brief, when the vaccine was given at the younger age schedule, the rotavirus IgA immune responses were generally lower to that given at the older age schedule. This difference was exacerbated by the concomitant administration of OPV [26]. Thus potentially two mechanisms may explain this observation.

PCV-7 has been shown in many studies to be highly immunogenic and

PCV-7 has been shown in many studies to be highly immunogenic and effective against IPD [5], [15], [16] and [17], with the vaccine efficacy of 97.4% against vaccine serotypes in the US [5]. In the large trial in South Africa and Gambia, the efficacy of PCV-9 was 83% and 77% against IPD caused by vaccine serotypes [18] and [19]. Twice as many IPD cases were indirectly prevented due to herd immunity after the PCV-7 implementation in the US [8]. Due to serotype specific efficacy of the vaccine, serotype coverage of IPD implies and predicts the efficacy of the vaccine. In this region, the serotype coverage of 70.3% by PCV-7 in IPD in children under five years of age in our study was less than the 78% coverage found in Singapore

[15], but higher than in a study in China in 2008 which found 63.6%, 64.8% and 79.6% coverage by PCV-7, PCV-10 and PCV-13, respectively [20].

The serotype coverage of IPD isolates by PCV-7 in children ≤14 years Epigenetic inhibitor old in Taiwan was 85%, somewhat higher than in our study [21]. WHO reported the overall serotype coverage of PCV-7 ranged from 60 to 85% worldwide [22]. There has been a concern about the increased proportion of nonvaccine serotypes reported in the US and Spain after introduction of PCV-7 vaccination program [8], [23] and [24]. The widely use of PCV-7 may contributed to the emergence of nonvaccine serotypes, especially serotype 19A [8], [23] and [24]. However, a study in Korea reported an increase in serotype 19A even before the introduction next of check details PCV-7 [25]. It is probable that both selective vaccine pressure and clonal spread were contributing factors to the circulating serotypes in the community. In Thailand, we reported the serotype coverage of PCV-7, PCV-9, PCV-11, and PCV-13 of 73.9%, 77.4%, 77.4%, and 87.8%, respectively, in children younger than 5 years of age during 2001–2005 [11]. The serotype coverage found in this study was somewhat lower than that report, but was still within the 95% confidential interval. Although PCV-7 has been available in Thailand since June 2006, the vaccine has been

used mainly in private settings with an estimated 55,000 doses sold each year, representing less than 5% of children <5 years of age. This low vaccine uptake did not seem to affect the serotype distribution in this relatively small study. The top seven serotypes of invasive isolates found in our study were different in rank of order and frequency (%) in each age groups, as well as whether the sites were sterile or non-sterile. Although the top seven serotypes of isolates from sterile sites in children younger than 5 years of age were not completely match with other studies reported earlier in Thailand [11], [26], [27] and [28], they were quite consistent. The common serotypes found in those and our studies were 6B, 14, 19A, 19F, 23F. The PCV that included all these serotypes, i.e. PCV-13, would be the most appropriate for large scale use in Thailand.

The X-axis of Fig. 3A1 and A2 illustrates the overall changes in these markers, with the responses separated for Crizotinib chemical structure each treatment group.

Also shown in Fig. 3A are IP-10 and IL-6 data at 24 h, a time point of peak elevation, and relationship to ALC or CRP. As expected, there was a correlation between the observed decrease in ALC and the increase in IP-10 levels 24 h after immunization (r = −0.76) ( Fig. 3A). Increased CRP at 48 h was associated with increased IL-6 at 24 h (r = 0.59) ( Fig. 3A). Additionally, there was a significant association of Day 28 TNA NF50 values reported by Hopkins et al. [14] with IP-10, IL-6, ALC, and CRP. In addition, Day 28 IgG antibody levels directed against PA (reported below) correlated significantly with these early innate biomarkers ( Fig. 3B). Fig. 4A presents the sequence of steps by which PBMC ELISpot data in each of 6 treatment groups were analyzed for responder rates. Using criteria to include only those PBMC pairs (day 0 and day 21) having adequate positive responses to PHA or CEF-I, the IFN-γ ELISpot responder rate to PAp and/or rPA averaged 11% (1/9) in recipients of two full (0.5 mL) doses of AVA. In contrast, a significantly higher IFN-γ response rate was observed Mdm2 antagonist for the subjects in treatment

groups that received the lower amount of CPG 7909 (0.25 mg), resulting in 5/11 and 7/12 positive responders for Formulations 2 and 4, respectively compared to those that received a higher amount of CPG 7909 (Suissa-Shuster, p = 0.03). There were no responders in the placebo group. Using the Suissa-Shuster unconditional

test [18], the IFN-γ responder rates of subjects immunized with AV7909 formulations containing half (formulations 3 and 4) compared to full (formulations 1 and 2) dose AVA were not statistically different (p = 0.57). Fig. 4B summarizes the IFN-γ T cell SFC cell count responses to PAp and/or rPA for each treatment group. ANOVA Statistics performed on the SFC counts in response to rPA (i.e. not on responder rate) demonstrated AV7909 F2 to be significantly different from AVA; this was not observed for the PAp mixture, however ( Fig. CYTH4 4B). The T cell IFN-γ response (reported as SFC) at Day 21 did not correlate with any of the other endpoints ( Fig. 3B). Of the investigated time points of Days 28, 42, and 70, IgG anti-PA content was highest in recipients of AV7909 compared to AVA, peaking at Day 28 (Fig. 5). IgG anti-PA content of 99 human serum samples obtained 14 days following the second immunization (study day 28) ranged from 21 to 160 μg/mL; this was a 5-fold or higher mean response for recipients of AV7909 compared to AVA. As expected, there was also an increase in mean serum content within AVA recipients (average 21 μg/mL on Day 28), compared to the saline (placebo) group. Significant correlations occurred between this parameter and the changes in both ALC and CRP (Fig. 3B).

The insertion of foreign objects into the male urethra is an interesting and anecdotal event

for most urologists. There is a wide variety of objects reported in the literature, and their unimaginable character makes the diagnosis and treatment as a challenge for any physician.5 However, a neglected or lost catheter in bladder and urethra is very rare because it might result from physician’s mistake. An amputated and completely intracorporeal catheter is not shown at gross appearance Selleckchem Palbociclib so that there is a high possibility to neglect and misdiagnose. Long-term neglected catheter may result in many complications and may require surgical procedures; therefore, physicians who involve managing urinary catheters should not ignore the possible existence of remnant segment after accidental

removal of the urethral catheter. We encountered a very rare case of an amputated and forgotten urethral Foley catheter in urinary bladder and urethra, which resulted in urethracutaneous fistula, with its proximal tip penetrating the urethral mucosa. We successfully removed that catheter with a flexible cystoscope. Physicians who handle the urethral catheter should be aware of complications associated with neglected urethral catheters. “
“The use of foreign bodies to enhance sexual experience is a practice that has been around for centuries. In fact, this practice is described in the Kama Sutra, and since that time numerous reports have been presented in the literature, indicating the increasing Romidepsin manufacturer popularity of this

practice.1 Stankov et al and Fischer et al have recently published reviews on implantation of artificial penile bodies. Both articles cite a predominance of the practice in Asia, with a relative paucity in Western culture. Neither review reports the practice in the United States. Fischer reports that in addition to penile enhancement for sexual pleasure of partner (63.9%), implantation of beads often ascribes an affiliation to a specific group (18.1%).2 A search on the Internet reveals that penile foreign body insertion is gaining popularity among laypersons, as attempts at self-insertion of these prosthetics have increased. We report a case of an incarcerated Caucasian American Thiamine-diphosphate kinase male patient with a subcutaneously self-inserted penile foreign body. A 29-year-old circumcised Caucasian male patient who was incarcerated at a midwestern prison presented to the urology clinic with the complaint of a wound on his penile shaft. He reported having placed a foreign body on the ventral aspect of his penis approximately 5 years before as a sexual pleasure device. He claimed that it was a domino, which he had shaved down and inserted under his penile skin. He noted erosion through the skin over the past several months, which was not painful. He desired removal of the object. A picture of the eroded prosthesis is seen in Figure 1.

The fidelity of the product was confirmed by mass spectrometric analysis of tryptic fragments, by the Medical Biomics Centre at SGUL. Fourteen UK captive-bred female cynomolgus macaques (Macaca fascicularis), aged between 4 and 5 years at the beginning of the experiment, were housed in accordance with the Home Office (UK) Code of Practice (1989). Animals were sedated with ketamine hydrochloride prior to procedures. Menstrual cycles were determined by the onset of bleeding. Animals were assigned to experimental groups (Table 1). Immunisation timings varied dependent upon individual menstrual cycles. Gp140

was formulated at 100 μg ml−1 in Carbopol gel as described previously [21]. 1 ml of the mixture was administered via a syringe inserted approximately 2 cm into the I-BET151 cell line vagina. For any one cycle of intravaginal inoculation, animals received formulated product on 9 occasions at 2–3 daily intervals during the inter-menses phase of the menstrual HDAC inhibitor cycle. For systemic immunisation, 100 μg gp140 was mixed with an equal volume of AS01 adjuvant and 0.2 ml injected into each deltoid

muscle. Secretions were sampled using pre-weighed Weck-cel surgical spears (Medtronic Ophthalmics, Jacksonville, FL) placed either on the cervical os or the vaginal wall for 1 min. After reweighing, secretions were eluted from the sponges as described previously [21]. 8 μl of heat inactivated foetal calf serum was added to pooled extracts before freezing aliquots at −80 °C. Total immunoglobulin concentrations Linifanib (ABT-869) in mucosal eluates were measured by sandwich ELISA. 96-well plates (medium binding, Greiner Bio-One, Stonehouse, UK) were coated with either goat anti-monkey IgG (γ-chain-specific) (KPL, Gaithersburg, USA) or goat anti-monkey IgA (α-chain-specific) (KPL) at 2 μg ml−1. After washing and blocking, as detailed below for antibody ELISA, mucosal eluates were added at dilutions of 1/100

and 1/1000. Bound immunoglobulin was detected by addition of goat anti-monkey IgG (Fc-specific) HRP conjugate (AbD Serotec, Kidlington, UK) or goat anti-monkey IgA (Fc-specific) HRP conjugate. Standard curves were derived using purified rhesus monkey IgG (SouthernBiotech, Birmingham, USA) or purified human IgA (Sigma, UK) and concentrations in mucosal secretions calculated taking into account the dilution factor derived from the weight of sample. Due to the unavailability of purified monkey IgA, results for this isotype were expressed as units (U) ml−1. Anti-gp140 binding antibodies were measured using a standardised ELISA. 96-well plates were coated with 50 μl per well of recombinant CN54gp140 at 5 μg ml−1 in PBS for 1 h at 37 °C. After washing four times in PBS containing 0.05% Tween 20 (PBS-T) reactive sites were blocked by incubation with PBS-T containing 10% foetal calf serum for 1 h at 37 °C. After further washing, serial dilutions of serum or mucosal eluates in PBS-T were added and incubated for 1 h at 37 °C.

ad libitum. Acute toxicity studies with Mengkudu fruit extract were performed in experimental rats. Graded doses of MFE (100, 250, 500, and 1000 mg/kg body weight) were administered orally, and the animals were subsequently observed for 2 weeks. Changes in body weight, food consumption, hematological, macroscopic, and clinical biochemical findings, including the activities of enzymes, were noted. Dosage fixation studies were carried out by virtue of unequally long administration of graded doses of MFE (100, 200, 300, 400 and 500 mg/kg body weight), given to rats introduced into STZ induced hyperglycemia; it was found that the MFE shows its maximal antihyperglycemic effect at the concentration BMS 387032 of 300 mg/kg body weight managed orally for 30 days. Hence, the dosage was fixed at 300 mg/kg body

weight/rat/day and tracked for 30 days. Streptozotocin, 2-deoxy-2-3-(methyl-3-nitrosoureido)-d-glucopyranose, is by far the most frequently used agent (69%) in preparation of diabetic animal models for the study of multiple aspects of diabetes, and the dose required for inducing diabetes depends on the animal species, route of administration and nutritional status.13 The experimental animals were fasted overnight and diabetes was experimentally induced by intraperitoneal injection Terminal deoxynucleotidyl transferase of STZ with a single dose of 50 mg/kg b.w./rat. STZ was dissolved in freshly prepared 0.1 M cold http://www.selleckchem.com/products/SP600125.html citrate buffer pH 4.5.14 Since STZ is capable of inducing fatal hypoglycemia as a result of massive pancreatic insulin release, STZ-treated rats were provided with 10% glucose solution after 6 h for the next 24 h to prevent diabetogen induced hypoglycemia.15 On 3rd day, the development and aggravation of diabetes in rats was confirmed and rats with fasting blood glucose concentration more than 250 mg/dL were selected for the experiments. The animals were divided

into four groups, comprising a minimum of six animals in each group as follows: Group 1 – control rats. The ethanolic extract of M. citrifolia fruits was subjected to preliminary phytochemical screening by standard methods. 16, 17, 18, 19 and 20 Blood glucose, hemoglobin and glycosylated hemoglobin were estimated according to the methods of Trinder,21 Drabkin and Austin,22 and Nayak and Pattabiraman23 respectively. Insulin level was measured in plasma using the sensitive rat insulin ELISA kit (Linco Research, Inc., St. Charles, MO) and the C–peptide assay was carried out by Rat C-Peptide RIA Kit. A portion of the liver and kidney tissues were dissected and washed immediately with ice-cold saline and were homogenized in 0.1 M Tris–HCl buffer (pH 7.4) for the assay of key enzymes of carbohydrate metabolism.
