A comparison between the effectiveness of erythromycin, single-dose clarithromycin and topical fusidic acid in the treatment of erythrasma
Although erythrasma is a superficial skin infection, there is no consensus on the treatment model of erythrasma. Objective: To compare the efficacy of erythromycin, single-dose clarithromycin and topical fusidic acid in the treatment of erythrasma in a double-blind, placebo-controlled, randomized trial. Methods: Hundred and fifty-one patients over 18 years of age were included in this study. Patients were randomized and divided into five groups. They received clarithromycin, erythromycin, fusidic acid cream, placebo cream or placebo tablets. Patients were evaluated by Wood's light reflection scores and the initial score values and the values on the days of 2, 7 and 14 were compared statistically. Results: According to the mean of Wood's light reflection scores, the efficacy of fusidic acid cream therapy was significantly higher than other therapies. When the efficacy of clarithromycin and erythromycin therapy was compared, clarithromycin therapy was significantly more effective than erythromycin therapy at 48 h. However, there was no statistical difference on the days of 7 and 14. Conclusion: Topical fusidic acid proved to be the most effective treatment; however, clarithromycin therapy may be an alternative regimen in the treatment of erythrasma because of its efficiency and better patient's compliance
Development of carbazole-bearing pyridopyrimidine-substituted urea/thiourea as polyphenol oxidase inhibitors: synthesis, biochemistry, and theoretical studies
Polyphenol oxidase (Tyrosinase, PPO) has received considerable attention, since it is the key enzyme in melanin biosynthesis. In this study, we investigated prepared novel carbazole-containing pyridopyrimidine-substituted with urea and thiourea derivatives and their PPO activities on the diphenolase activity of banana tyrosinase. The structures of the compounds synthesized were confirmed by 1 H NMR, 13 C NMR, FTIR and elemental analysis. PPO enzyme was purified from banana on an affinity gel comprised of Sepharose 4B-L-tyrosine-p-amino benzoic acid. For evaluating the enzyme activity, the synthesised compounds were subjected to tyrosinase inhibition assay using catechol as substrate. While some of the compounds (6, 7, 8f, 8h, 8i, 8j) showed enzyme inhibitor effect, some of them (8a, 8b, 8c, 8d, 8e, 8g, 8k) activated the PPO enzyme activity. Gaussian software was used for the molecular calculations to explain the results for the prepared compounds
Physical inactivity and low quality of life in Turkish women after hospitalization for coronary heart disease: inferences from EUROASPIRE III
Objective: The present objective was to compare changes in lifestyle between (i) Turkish women and Turkish men, and (ii) Turkish women and European women, after hospitalization for coronary heart disease (CHD). Risk factor management, physical activity, mood, and quality of life (QOL) indices were compared
Synthesis and carbonic anhydrase inhibitory properties of new spiroindoline-substituted sulphonamide compounds
New spiroindoline-substituted sulphonamide compounds were synthesised and their inhibitory effects on the activity of purified human carbonic anhydrase I and II were evaluated. Human carbonic anhydrase isoenzymes (hCA-I and hCA-II) were purified from erythrocyte cells by affinity chromatography. The inhibitory effects of the 14 synthesised sulphonamides (6a-n) on esterase activities of these isoenzymes were studied in vitro. In relation to these activities, the inhibition equilibrium constants (K-i) were determined. The results showed that all the synthesised compounds inhibited the carbonic anhydrase (CA) isoenzyme activity. Among them, 6b was found to be the most active (K-i: 0.042 mu M) for hCA I and 6a (K-i: 0.151 mu M) for hCA II
