RESUMO
The treatment of chronic inflammatory skin conditions are not satisfactory. There is a need for better antiflammatory drugs for these conditions. This study was done to compare the efficacy of biopolymer based formulations of clobetasol propionate and clobetasol butyrate with commercially available Preparations of clobetasol in animal models of superficial skin inflammation in rats. The croton oil ear edema in rats was the chronic inflammatory model used in this study. In this model, the animals treated with clobetasol propionate and clobetasol butyrate with biopolymer showed a significant decrease in inflammation as compared to commercially available preparations of clobetasol(Tenovate and Eumosone).
RESUMO
Topical antibiotic like Calcium mupirocin and its combination with steroid Fluticasone are commonly used to treat burn wounds. But whether they influence healing of wounds is not known. Aim: To compare the effect of Calcium mupirocin and Fluticasone of Apex Laboratories Chennai, on experimentally induced burn wound healing in Wistar rats and compare with available market preparation Mupirocin and Fluticasone -mupirocin combination. Method: Partial thickness burn wound was inflicted, on Wistar rats under ketamine (50mg/kg/i.p) by pouring hot molten wax at 80◦ C into a metal cylinder of 300 mm2 circular opening placed on shaven back of the rat. Animals with partial thickness burn wounds were divided into 7 groups (n=10). Group I did not receive any drug and served as control group. Group II, III, IV, V, VI, and VII received Calcium mupirocin A, Calcium mupirocin B, Mupirocin, Fluticasone+Calcium mupirocin A combination. Fluticasone +Calcium mupirocin B combination and Fluticasone -mupirocin combination creams respectively, twice a day for 21 days or till complete healing whichever was earlier. Results: Calcium mupirocin significantly decreased the duration of epithelialization and increased % of wound contraction in comparison to the control group. This was confirmed by Histopathology studies. Conclusion: Calcium mupirocin of apex possess significant wound healing properties.
RESUMO
The safety of thrombolytic therapy for acute myocardial infarction in the elderly population has not been clearly established. In a retrospective study we evaluated the efficacy and complications of thrombolytic therapy in the elderly as compared to younger patients. Consecutive 588 patients who received thrombolytic therapy were studied. Clinical data in 136 patients aged above 65 years were compared with 85 patients below 40 years. Cigarette smoking was a common risk factor in the young (46 vs 13; p < 0.0001). Coexistent systemic diseases and conduction system disturbances (28 vs 9; p < 0.05) were common in the older patients, but the incidence of bleeding complications to thrombolytic therapy (6 vs 1; p = NS) was not found to be higher. Ninety percent of the elderly who had cardiogenic shock died. There was no significant difference between the two groups in reinfarction rate (12 vs 15; p = NS) and post-infarct angina (20 vs 20; p = NS). Coronary angiography revealed a higher incidence of multivessel disease in the elderly. To conclude, thrombolytic therapy is safe and effective even in older individuals.
