Withania somnifera (L.) Dunal, shows several pharmacological properties which are attributed mainly to the withanolides present in the root. The efficacy of medicinally active withanolides constituents depends on the absorption and transportation through the intestinal epithelium. We examined these characteristics by employing the Sino-Veda Madin-Darby canine kidney cells culture system, which under in vitro condition shows the absorption characteristics similar to the human intestinal epithelium. Thus, the aim of the present investigation was to assess the bioavailability of individual withanolides. Withanolides were diluted in Hank's buffered saline at a concentration of 2 μg/ml were tested for permeability studies carried out for 1 h duration. Permeability was measured in terms of efflux pump (Peff ) in cm/s. Peff values of withanolide A (WN A), withanone (WNN), 1,2-deoxywithastramonolide (1,2 DWM), withanolide B (WN B), withanoside IV-V (WS IV-V), and withaferin A were 4.05 × 10−5 , 2.06 × 10−5 , 1.97 × 10−5 , 1.80 × 10−5 , 3.19 × 10−6 , 3.03 × 10−6 and 3.30 × 10−7 respectively. In conclusion, the nonpolar and low molecular weight compounds (WN A, WNN, 1,2 DWM, and WN B) were highly permeable. As against this, the glycosylated and polar WS IV and WS V showed low permeability. Surprisingly and paradoxically, the highly biologically active withaferin A was completely impermeable, suggesting that further studies possibly using human epithelial colorectal adenocarcinoma (Caco-2) cells may be needed to delineate the absorption characteristics of withanolides, especially withaferin A.

Spontaneous reporting (SPR) and intensive monitoring are the conventional systems used for detecting, recording, and reporting adverse drug reactions (ADRs). Using spontaneous reporting a lot of successes has been made as existing ADRs were identified and new ones prevented through this methods. The aim of this appraisal was to evaluate the knowledge, attitude, and the practice of medical students with regards to ADRs reporting and to see if differences exist between the level of study and genders. The questionnaire was adopted, modified, and validated from previous studies. It comprised of 25 questions. It was administered year-IV and V medical students of Bayero University Kano, Nigeria. The data collected were coded and analyzed using the Statistical Package for the Social Sciences (SPSS) version 20, currently known as IBM SPSS Statistics. The response rate was 74%. Among the 108 participants, 80% got the definition of ADRs correct; 63% of them knew the precise functions of pharmacovigilance (PV). In addition, 82% strongly agreed that ADR reporting is health care workers responsibility; 82% also said PV should be taught in detail. Meanwhile, 99% have noticed patient experiencing ADRs; 67% said even mild ADRs should be reported. The outcome of this study showed good knowledge and attitude with respect to ADRs and PV among the medical students surveyed. Unfortunately, the practice of medical students was found to be unsatisfactory. There is a need to upgrade the students teaching the curriculum with respect to ADRs monitoring.

The issue of male germ line mutagenesis and the effects on developmental defects in the next generation has become increasingly high profile over recent years. Mutagenic substance affects germinal cells in the testis. Since the cells are undergoing different phases of cell division and maturation, it is an ideal system to study the effect of chemotherapeutic agents. There are lacunae in the literature on the effect of sorafenib on gonadal function. With background, a study was planned to evaluate the effects of sorafenib on sperm count and sperm motility in male Swiss albino mice. Male Swiss albino mice were used for the study. The animals were segregated into control, positive control (PC) and three treatment groups. PC received oral imatinib (100 mg/kg body weight) and treatment groups received 25, 50, and 100 mg/kg body weight of sorafenib orally for 7 consecutive days at intervals of 24 h between two administrations. The control group remained in the home cage for an equal duration of time to match their corresponding treatment groups. The animals were sacrificed at the end of 1 st , 2 nd , 4 th , 5 th , 7 th , and 10 th weeks after the last exposure to drug, respectively. Sperm suspensions were prepared and introduced into a counting chamber. Total sperm count and motility were recorded. There was a significant decrease in sperm count and sperm motility by sorafenib which was comparable with the effect of PC imatinib. Sorafenib adversely affects sperm count and sperm motility which are reversible after discontinuation of treatment.

Nymphaea nouchali Burm. f. (Family - Nymphaeaceae) is a well-known medicinal plant used in the Indian ayurvedic system of medicine for treating diabetes. The seeds especially have been prescribed for diabetes. The hydroalcoholic extract of N. nouchali seeds has been demonstrated to possess anti-hyperglycemic effects in diabetic rats, but the functional mechanism remains unknown. The nuclear receptor, peroxisome proliferator-activated receptor gamma (PPARγ) is noted to play an important role in glucose and lipid homeostasis. This study was hence focused in evaluating the effect of the extract on PPARγ activation, adipocyte differentiation, and glucose consumption in 3T3-L1 cells. Cell viability was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT), followed by adipogenesis assay using Oil Red O technique. Glucose consumption of preadipocytes and adipocytes in the presence of the extract was also determined. Real-time polymerase chain reaction was performed to identify the expression of genes involved in glucose consumption in the adipocytes. MTT assay confirmed the extract to be nontoxic, and Oil Red O staining confirmed enhanced adipocyte differentiation of 3T3-L1 cells in a dose-dependent manner. The extract also increased the expression of PPARγ target gene, which in turn enhanced the expression of GLUT-4. The data, therefore, suggests that N. nouchali seed extract promotes adipocyte differentiation and glucose consumption by inducing PPARγ activation, which in turn increases mRNA GLUT-4 expression and subsequently enhances insulin-responsiveness in insulin target tissues.

The study is aimed to assess the incidence of drug-related problems (DRPs) and provide pharmacist interventions for identified DRPs. A prospective, observational study was conducted among 189 patients with cardiovascular disease who were aged 18 years or older and admitted to the general medicine in-patient ward. During the 6 months study period, the incidence of DRPs was identified using Pharmaceutical Care Network Europe Foundation classification system version 6.2. A total of 189 patients were screened for DRPs. Among them, 130 patients have at least one DRP. A total of 416 DRPs were identified (on average, 2.2 DRPs per each patient). Of the 416 DRPs, 125 (30.04%) interventions were accepted, 7 (1.68%) interventions were not accepted, while remaining (68.26%) accepted but no action taken. The results of the study indicate that incidence of DRPs is substantial and pharmacist-led interventions resulted in resolution of DRPs. This represents the need for the active role of the clinical pharmacist in the developing countries like India.

Biophytum sensitivum (L.) DC (family: Oxalidaceae) has been used in the Indian indigenous system of medicine, Ayurveda, for the treatment of various health aliments including renal calculi. The present study was undertaken to investigate the anti-urolithiatic activity of standardized methanolic extract of whole plant of B. sensitivum (MBS) in rats. Urolithiasis was induced by surgical implantations of zinc disc in the urinary bladders of rats. Upon postsurgical recovery, different doses of MBS (viz., 100, 200, and 400 mg/kg body weight) were administered to zinc disc-implanted rats for the period of 7 days by the oral route. Anti-urolithiatic activity was evaluated by measuring various dimensions of stones and estimating levels of various biomarkers in serum and urine samples. A significant decrease in urinary output was observed in the disc-implanted animals, which was prevented by the MBS treatment. Supplementation with MBS caused significant improvement in glomerular filtration rate and protein excretion. The elevated levels of serum creatinine, uric acid, and blood urea nitrogen were also prevented by the MBS treatment. The MBS treatment showed reduced formation of deposition around the implanted zinc disc. The higher dose of MBS (400 mg/kg) found more effective. These results indicate that the administration of MBS significantly prevents the growth of urinary stones. The possible mechanism underlying this effect is mediated collectively through diuretic, antioxidant and anti-inflammatory effects of the plant. The results concluded that the methanolic extract of whole plant of B. sensitivum possessed significant anti-urolithiatic activity.

Staphylococcus aureus is a common nosocomial pathogen with property to develop resistance to antimicrobial agents. But in the modern era, drug resistance had been developed by microbes due to its continuous usage of antibiotics. This study was carried out to evaluate antibiotic resistant pattern of methicillin resistant Staphylococcus aureus (MRSA) using molecular genotyping. In view of the present problem, the study has been conducted to detect the molecular genotyping of mecA gene from MRSA and confirmation of its restriction sites using EcoRI and BamHI. The pus samples were swabbed out, and clinical strains were isolated using standard microbiological procedures. Then the strains were subjected to in vitro antibiotic susceptibility assay and identified MRSA. Further molecular genotyping of mecA gene was determined by polymerase chain reaction technique. The percentage analysis was done. The clinical strains were isolated from the wound infected patients. A total of 60 samples were collected, of 60 samples, 40 (66.7%) were showed positive to strains of S. aureus. The in vitro antibiotic susceptibility assay was carried to find the drug sensitive and resistant patterns. Further methicillin resistant strains (35%) of S. aureus were screened and subjected to molecular genotyping of mecA gene and was confirmed by restriction digestion. Overall, 70% of plasmids show positive for the presence of mecA gene, although all strains have restriction sites. Hence, the present study revealed that the early detection of antibiotic resistant character using molecular genotyping will help the infected patient to cure short period and will reduce the development of multidrug resistance.

Chewing the habit of blended pan masala containing areca nut with or without tobacco is a common practice in the Indian subcontinent. Arecoline, a pyridine alkaloid presence in areca nut alarmed for oral carcinogenesis and strictly prohibited in the western world. However, in India using blended pan masala is very popular among young and old individuals. In this context, we aimed to detect arecoline in Indian blended nontobacco pan masala sold in Kolkata using a simple densitometric high-performance thin-layer chromatographic (HPTLC) method and for alarming their use in common people. Eleven popularly Indian blended nontobacco pan masala were collected from the territory of Kolkata and isolated arecoline, following solvent extraction method derived for pyridine alkaloid. The quantitative analysis of arecoline was measured using automated software-based HPTLC instruments and validated the method according to International Conference on Harmonization guidelines. Arecoline was detected in all 11 blended nontobacco pan masala samples in a range of minimum 130 to maximum 415 μg/g dry samples. Arecoline is hazardous carcinogenic compound, so the use of Indian blended nontobacco pan masala should be restricted. Further, the method was found suitable for routine quantitative analysis of arecoline in areca nut containing substances.
