ObjectiveD-galactose has been commonly used in rodent models to induce accelerated effects of aging, including those on learning, memory, and muscular tone and coordination. This is normally seen on chronic administration of D-galactose. However, there is minimal suggestive evidence on the short-term effects of the same. The aim of the study was to study the acute and chronic effects of D-galactose on learning and memory in Wistar rats.MethodsTwenty four male Wistar rats were randomly assigned to the control, standard (rivastigmine), oral D-galactose (200 mg/kg/day) and subcutaneous D-galactose (200 mg/kg/day) for a total duration of 8 weeks. Effects on learning and memory were assessed at 2 weeks, 4 weeks and 8 weeks by Morris water maze model and passive avoidance testing.ResultsBoth oral and subcutaneous D-galactose showed positive effects on learning and memory on acute dosing, whereas this beneficial effect was lost during chronic dosing.ConclusionShort-term administration of D-galactose showed positive effects, while long-term administration nullified these effects.

Objectives:Statins by their anti-inflammatory and endothelial stabilizing effect can be beneficial in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH). The present study was done to evaluate the effect of rosuvastatin on pulmonary functions and quality of life (QOL) in patients with concomitant COPD and PH.Materials and Methods:It was a prospective, randomized, double-blind, placebo-controlled, study conducted in patients with COPD and PH. A total of sixty patients were assigned to receive either rosuvastatin 10 mg or placebo once a day in addition to their conventional treatment for 12 weeks. Routine blood investigations, pulmonary functions, echocardiogram, exercise capacity, and QOL using a questionnaire were assessed at the baseline and after 12 weeks.Results:In patients of rosuvastatin group, there was a statistically significant increase in peak expiratory flow rate (PEFR) (P = 0.04) but no significant change in other pulmonary functions: Forced vital capacity (FVC), forced expiratory volume at 1 s (FVC, FEV1, FEV1/FVC), and echocardiogram parameters. There was a significant increase in 6-min walk test (6-min walk distance) (P = 0.03) at the end of 12 weeks. On comparing with placebo, rosuvastatin showed a significant reduction (P = 0.045) in COPD exacerbations while adverse effects did not differ.Conclusion:Statins have a favorable effect on patients with COPD and PH regarding the improvement in PEFR, COPD exacerbations, and exercise capacity. Such effects can be beneficial in these patients and more so in patients with concomitant coronary artery disease or hyperlipidemia where long-term benefits of statins have been established.

Introduction: The Indian Diabetes Risk Score is a tool which was devised by the Madras Diabetes Research Foundation to screen people for the risk of developing Diabetes mellitus; it comprises of the family history, the abdominal circumference, age and the physical activity. Aim of the Study:This study was aimed at finding out whether the Indian Diabetes Risk Score (MDRF) correlated with the blood sugar levels, the lipid profile and the blood pressure readings of medical students.Methods: Seventy five female and 75 male students who signed the informed consent were selected for the study. Their IDRS was calculated by using a validated questionnaire which involved the family history, the abdominal circumference, age and the details of the physical activity. All of them had their blood pressure, fasting plasma glucose and lipid profiles measured.Results: There were 101 students with an IDRS of <30, 42 students with a moderate IDRS (30-50) and 7 who had a high IDRS of ≥60. The fasting plasma glucose was significantly correlated with the IDRS (P=0.001, r = 0.472), with a mean FPG of 84 ± 3.63mg/dl in the low risk groups, of 88 ± 4.93mg/dl in the moderate risk groups and of 94 ± 6.50mg/dl in the high risk groups. The total cholesterol value was r = 0.420 (P= 0.001), the total triglycerides value was r = 0.373 (P=0.001), the LDL cholesterol value was r = 0.578 (P=0.001) and the VLDL value was r = 0.566 (P=0.001), which positively correlated with the risk score and the HDL value r = -0.480 (P=0.001) correlated negatively with the risk score. There was no correlation between the IDRS and the blood pressure. Conclusion:Our study showed that nearly 40% of the medical students had a moderate to a high IDRS. The IDRS significantly correlated with the fasting plasma glucose and with all the components of the lipid profile. The IDRS did not correlate with the blood pressure readings. INTRODUCTIONDiabetes is one of the major non-communicable diseases of the world and India has the dubious distinction of being the "diabetic capital" of the world. We have 40 million Indians with diabetes this forms the largest diabetic pool in the world [1]. The major threat is that 66% of the population of the Indian diabetic pool is undiagnosed. The rise in diabetes in India can be attributed to the genetic predisposition, the sedentary life-styles and the changing food habits.It has been found that 66% of the Indian diabetes cases are not diagnosed, as compared to 50% in Europe and 33% in the USA. A diabetes risk score will help in devising effective screening strategies to unmask the hidden burden of the disease. The risk factor approach needs aggressive identification for planning prevention strategies and for an early diagnosis. Several diabetes risk scores or risk engines have been devised for prevention programmes in the USA, Scandinavia and in the UK. Mohan et al., from their Chennai Rural Epidemiology Study (CURES) cohort, have developed a single user friendly Indian diabetic risk score [2] (MDRF-IDRS), which takes into consid...
