Losartan potassium, a highly effective blood pressure lowering agent, has widely used for treatment of hypertension. Simple, economic, selective, and precise and stability indicating HPLC method has been developed and validated for analysis of losartan potassium in bulk drug and formulation dosage form. In order to optimize more one response at time, the chemo metric approach which includes 23 factorial design at two level with three factors was set up to standardize the chromatographic condition. The mobile phase was 40:60 ACN: Buffer consist of 0.05% of orthophosphoric acid and 0.05% Triethylamine at flow rate 1.0ml/minute the eluent was monitored at 225nm. The calibration plots constructed using the concentration of 6.4 to 9.6µg/ml (80 -120%) with r2 =0.999, recovery =99.44% was indicative of accuracy of proposed method. The precision was calculated as repeatability, intraday (RSD) for the...

Oral squamous cell carcinoma (OSCC) is often associated with a lymphocytic infiltrate that is believed to represent an in vivo immune reaction to the tumor cells. In this study, the tumor-infiltrating lymphocytes (TIL) associated with primary OSCC were characterized in hundred newly-diagnosed patients to determine the nature of the immune response to the primary tumor and to correlate it with stage and grade of the disease in order to derive its significance. TILs were estimated in surgically removed oral cancer tissue, histopathologically and with immunohistochemistry, using antibody against CD3 (Dakopatts, Denmark). TIL were estimated in intratumoral and peritumoral areas and arbitrarily graded in to four groups. Site wise CD3 infiltration was found maximum in buccal mucosa and minimum in tongue, rest of the cases being distributed in other locations and the distribution showed statistical significant in intratumoral location. There was no significant correlation between tumor size and CD3 infiltration. Further CD3 infiltration was not related to either lymph node enlargement or bone involvement, however it was more in intratumoral...

Cyclocondensation of 5-6 and 7-8 with chloroacetyl chloride in presence of triethylamine give 9-10 and 11-12 respectively. All the synthesized compounds 1-12 have been screened for their antibacterial as well as antifungal activities and compared with reference drugs streptomycin and fusidic acid respectively. These synthesized compounds were screened for their antibacterial activity against S. aureus and B. subtillis and antifungal activity against A. niger and C. albicans. The melting points were determined in open glass capillaries tubes. Purity of the compounds was checked by thin layer chromatography (TLC) on silica gel G plates and spots were located by using iodine chamber. All the newly synthesized compounds were confirmed by elemental (C, H, N) and spectral IR, 1HNMR analysis. In this series compound 10 showed better antibacterial activity than reference drug streptomycin and compounds 10 and 12 were found to be more potent antifungal agents than reference drug fusidic...

The present work was designed to perform the comparative study between the seeds of two selected plants i.e., Butea monosperma & Nigella sativa. The study includes phytochemical screening of primary and secondary metabolites, physico-chemical analysis, pharmacological studies, elemental analysis, and flouroscent studies. The comparative priliminary studies of Butea monosperma and Nigella sativa seeds in different solvent extracts shows the presence of primary metabolites such as carbohydrates, proteins, lipids and secondary metabolites such as Alkaloids, phenolic compounds, Flavonoides, Steroids, Tannins & saponins etc. In the preliminary screening of Nigella sativa ethanolic extract was more effective and shows the presence of maximum number of secondary metabolites, whereas In the preliminary screening of Butea monosperma methanolic extract was more effective and shows the presence of maximum number of secondary metabolites. The pharmacognostic studies was also carried out in order to check the adulteration and quality of crude drugs, which involves the evaluation of organoleptic characters such as colour, odour, taste and other macroscopical physical characters. The comparative physicochemical analysis of total ash...

Patients with DM are often afflicted by debilitating urologic complications. The main aim of this study is to investigate the effect of streptozotocin (STZ)-induced type I diabetes on contractile responses to numerous stimuli, intracellular cation concentrations and morphology in the rat. Adult rats (n=12) were humanely killed and detrusor muscles of urinary bladder located and excised rapidly and placed in organ baths. Then urinary bladder detrusor muscles were blotted, weighed and dissolved in concentrated nitric acid for the measurements of cation contents. The diabetic rats had significantly (P<0.05) elevated blood glucose compared to control rats. The contractile responses induced by EFS were significantly (P<0.05) increased in the diabetic urinary bladder tissue in comparison to the control urinary bladder tissue. The increase in the contractile force was calcium-dependent in both control and diabetic urinary bladder tissues. The results also showed no significant differences in the levels of sodium, potassium, calcium, between the diabetic and control urinary bladder (p>0.05). However, there was a significant (P<0.05) decrease in magnesium in the diabetic...
