Viral gastroenteritis is one of the major causes of childhood mortality in India. About 30 to 50 % gastroenteritis caused by unknown etiological agents. This study was aimed to identify unknown RNA viral etiology and their clinical manifestation with pediatric acute gastroenteritis, conducted at tertiary care hospital of Uttar Pradesh, North India from July 2012 to December 2013. A total of 234 patients with their clinical profiling were enrolled in this study. Identification of viruses was performed by serological (ELISA for rotavirus) and molecular methods (PCR for astrovirus, norovirus and cosavirus). Quantitative and qualitative data analysis performed by Chi-square and student t-test. Total subjects positive for infection was 35%.Co-infection present in 21% cases. Rotavirus, astrovirus, norovirus and cosavirus were detected in 25%, 10%, 7% and 3% subjects respectively. Other than diarrhea, vomiting was a significant symptom (p=0.0002). Severity of diarrhea was more than vomiting with 5.5±2.7 vs. 3.3±2.6 episodes in 24 hrs. Mean duration of symptoms 3.7±9.1. Eighty percent virus positivity were below the age of 6 years (39.2...

The aim of the research work was to develop and optimize fast dissolving tablets of Promethazine Thecolate by direct compression using effervescent technology. For the investigation, purpose a 32 full factorial design was used to know the joint influence of two formulation variables, Crospovidone and Citric acid. The formulated tablets were evaluated for its percent friability and their disintegration time. The results of multiple linear regression analysis revealed that for obtaining a rapidly disintegrating dosage form, tablets should be prepared using an optimum concentration of sodium starch glycolate and a crospovidone. A contour plot was also presented to graphically represent the effect of the independent variables on the disintegration time 30 s and percent friability 0.5 %. A checkpoint batch was also prepared to prove the validity of the evolved mathematical model. The optimized tablet should be prepared with an optimum amount of Sodium starch Glycolate (2.75 mg), and Crospovidone (2.72 mg) which disintegrated in the 30 seconds, with friability of 0.5% and of drug release within 5 min....

Vitex negundo is an Indian medicinal plant used to cure several diseases such as asthama, fever, headache, cancer and many other diseases. This study aims to determine the antioxidant potential and anti-proliferative activity of Vitex negundo methanolic leaf extract. Isolation of bioactive compounds involved liquid-liquid extraction of methanolic leaf extract by petroleum ether and chloroform. The total antioxidant potential of the extracts was determined using phosphomolybdenum, 2,2-Diphenyl-1-picrylhydrazyl (DPPH), Ferric oxide reducing power (FRAP) and Nitric Oxide methods. It was observed that the crude and chloroform extracts had good antioxidant activity. The antileukemic activity of the chloroform extract was tested on HEL92.1.7 and Jurkat cell lines (Acute lymphoblastic leukemia derived) by cytotoxicity assay (MTT). The plant extracts exhibited poor cytotoxicity against the erythroid cell lines but showed good cytoxicity on Acute lymphoblastic leukemia cells. This study shows that the chloroform fraction of V negundo leaf has both antioxidant and antileukemic...

Although many studies have demonstrated the importance of the apoB/apoA-1 ratio as a risk marker of atherogenicity, less is known about apoB/apoA-1 ratio in predicting and the severity of coronary artery disease (CAD) in T2DM. Our study aimed to assess possible associations between apoB/apoA-1 ratio levels and the severity of coronary artery diseases in patients with type 2 diabetes mellitus (T2DM). Plasma levels of lipidic profile components, apolipoproteins and the apoB/apoA-1 ratio were determined in 148 CAD patients with T2DM and in 159 patients with only CAD. Cut off value of the apoB/apoA-1 ratio was determined from 207 healthy subjects. Severity of CAD was quantified according to the prevalence of multivessel disease and the degree of coronary stenose. Association between the apoB/apoA-1 ratio and the severity of CAD were evaluated using the receiver operating characteristic (ROC) curve and apoB/apoA-1 ratio. ApoB/apoA-1 ratio levels didn’t show significant differences between DM and NDM patients (DM: 0.9±0.5; NDM: 0.8±0.5; P=0.529). In contrast, difference was significant between these groups when patients were categorized...

Bis-[1,5]-benzothiazepines (3a-i) containing two 1,5-benzothiazepine nuclei in a single molecule were synthesized by cyclocondensation reaction of bis-chalcones (1a-i) with two equivalent of 2-aminobenzenethiol (2). All the synthesized compounds were characterized by IR, 1H NMR,13C NMR and mass spectral analysis. Anticancer activity of the synthesized compounds against human breast cancer cell line MCF-7 was determined and the compound (3c) showed significant activity comparable to...
