Reproductive toxicity of sodium valproate in male rats.

Objectives: To assess the effects of sodium valproate on rat sperm morphology, sperm count, motility, and histopathological changes in testis. Materials and Methods: Male Wistar rats (12 week old) were treated with sodium valpraote and sacrificed at the end of 2nd, 4th, 5th, 7th, 10th and 15th week after the last exposure to sodium valproate. Epididymal sperm count, sperm motility, sperm morphology, and histopathology of testes were analyzed. Results: Sperm count and sperm motility were decreased significantly by sodium valproate. The percentage of abnormal sperms increased in a dose-dependent manner. A histopathological study revealed that sodium valproate had caused sloughing of epithelial cells in testes. Conclusion: Sodium valproate causes reversible change in sperm motility, sperm count, morphology, and cytoarchitecture of testes.

Cost of Adverse Drug Reactions in a South Indian Tertiary Care Teaching Hospital

In India, very few reports on the cost of adverse drug reactions (ADRs) are available. There is a need to study this aspect of health care in order to understand the economic burden imposed by ADRs. The aim of the current work was to study the costs associated with documented ADRs in a tertiary care teaching hospital. This study was conducted in medical wards of a south Indian tertiary care teaching hospital over a 6‐month period. The study protocol was assessed and approved by the institutional ethics committee. A total of 317 ADRs from 246 patients were identified during the study period. The present study used an intensive monitoring method to detect ADRs and assessed an incidence of 32.7% adverse reactions in the monitored group. The causality, severity, predictability, and preventability of the documented ADRs were assessed. The total cost to the hospital due to ADRs was found to be Rs. 1,567,397 (US

Development of a Predictor Model for Quality of Life in Cancer Patients with Adverse Drug Reactions due to Cancer Chemotherapy.

Low Lead Exposure During Foetal and Early Postnatal Life Impairs Passive Avoidance Learning in Adulthood in Rats This follow-up study investigated the effects of low-level lead exposure during prenatal and early postnatal period on learning and memory in rats immediately after exposure has ceased at weaning and later in their adulthood. Male Wistar-derived rats were exposed to lead (as 0.2 % lead acetate solution) through their mothers during pregnancy and lactation until they were weaned. Mothers of control rats were given tap water during pregnancy and lactation. All pups were weaned on tap water at 21 days of age and were followed up until 120 days old. Low-level lead exposure did not affect their body weight at any time during the experiment. Blood lead in the exposed rats was significantly higher on postnatal day 22 and dropped to control values by day 120. Passive avoidance test showed impaired memory retention in the exposed rats on postnatal days 25 and 120. This suggests that exposure to low-lead levels during foetal and early postnatal development of brain tissue can cause memory impairment that lasts into adulthood. Izloženost štakora niskim razinama olova tijekom fetalnog i ranoga postnatalnog razvoja šteti učenju pasivnim izbjegavanjem kazne kasnije u odrasloj dobi Cilj je ovoga prospektivnog istraživanja bio utvrditi kako izloženost niskim razinama olova tijekom gestacije i ranoga postnatalnog razvoja utječe na učenje i pamćenje u štakora odmah nakon prestanka izloženosti (odbijanjem od sise) te kasnije u odrasloj dobi. Mužjaci štakora izloženi su olovu u obliku 0,2 %-tne otopine olovova acetata preko majke tijekom gestacije te za cijeloga trajanja laktacije sve do odbijanja od sise. Sve to vrijeme majke kontrolnih štakora dobivale su vodu iz pipe. Svi su štakorčići odbijeni od sise 21 dan nakon okota i otada piju vodu iz pipe. Praćeni su do 120. dana života. Izloženost niskim razinama olova nije dovela do razlika u tjelesnoj težini između izloženih i kontrolnih štakorčića. Razine olova u krvi bile su značajno više u izloženih štakora 22 dana od okota, da bi do 120. dana pale na razinu u kontrolnih štakora. Test pasivnoga izbjegavanja pokazao je oštećenje pamćenja u izloženih štakora 25. i 120. dana nakon okota. To potvrđuje da izloženost niskim razinama olova tijekom fetalnoga i ranoga postnatalnog razvoja moždanog tkiva može dovesti to oštećenja u pamćenju koje traje sve do odrasle dobi.

A Study to Assess the Therapeutic Effect of Enalapril on Olanzapine Induced Metabolic Syndrome in Wistar Rats

Neuropsychological studies in children who are exposed to lead during their early brain development have shown to develop behavioural and cognitive deficit. The aim of the present study was to assess the cellular damage in hippocampus, amygdala and cerebellum of rat pups exposed to lead during different periods of early brain development. Five groups of rat pups were investigated. (a) Control group (n = 8) (mothers of these rats were given normal drinking water throughout gestation and lactation), (b) pregestation lead-exposed group (n = 8) (mothers of these rats were exposed to 0.2% lead acetate in the drinking water for one month before conception), (c) gestation lead-exposed group (n = 8) (exposed to 0.2% lead acetate in the drinking water through the mother throughout gestation [gestation day 01 to day 21]), (d) lactation lead-exposed group (n = 8) (exposed to 0.2% lead acetate in the drinking water through the mother throughout lactation [postnatal day 01 to day 21]) and (e) gestation and lactation lead-exposed group (n = 8) (exposed to 0.2% lead acetate throughout gestation and lactation). On postnatal day 30, rat pups of all the groups were killed. Numbers of surviving neurons in the hippocampus, amygdala and cerebellum regions were counted using cresyl violet staining technique. Histological data indicate that lead exposure caused significant damage to neurons of hippocampus, amygdala and cerebellum regions in all lead-exposed groups except lactation lead-exposed group. The extent of damage to neurons of hippocampus, amygdala and cerebellum regions in lactation lead-exposed group was comparable to gestation and lactation groups even though the duration of lead exposure was much less in lactation lead-exposed group. To conclude, the postnatal period of brain development seems to be more vulnerable to lead neurotoxicity compared to prenatal period of brain development.

Antidepressant-related jitteriness syndrome in anxiety and depressive disorders: Incidence and risk factors

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.

Advances in pharmacovigilance initiatives surrounding antimicrobial resistance-Indian perspective.

Cancer is one of the leading causes of morbidity and mortality worldwide. There are various detrimental symptoms experienced by a cancer patient due to the disease and the undergoing treatment which adversely affects the Quality of Life (QOL) in these patients. Therefore, QOL and its evaluation have turned out to be progressively vital in the health care system. Hence, the aim of our study was to develop a predictor model to predict the QOL in cancer patients receiving chemotherapy. The study was carried out in the Department of Radiotherapy and Oncology, Kasturba hospital, Manipal, a tertiary care hospital. Predictor model was developed to predict the Quality of Life Scores (QOLS) using multivariate regression analysis. A total of 387 patients participated in the study. Mean age of the patients was 50.85 ± 11.82 years (95% CI, 49.66-52.03). In our study, 16.54% had poor global health status/QOL, 72.35% had average and 11.11% had a high global health status/QOL. A significant difference was found in the QOLS based on the age group, site of cancer, drugs used in treatment of cancer, age as a predisposing factor and organ system affected due to ADRs (respiratory system, sensory system, skin and appendages). In the predictor model, the Coefficient of determination R-square (R2) was found to be 0.3267 indicating that 32.67% of the variation in the ‘quality of life score’ is explained by the independent variables included in the model. The F (45, 341) = 3.67, p < 0.001 indicating the overall significance of the regression model. Thus, the study showed that there are various predictors that can assess the QOL in cancer patients which can further serve as a guide to implement timely interventions to improve patients QOL.
