Recently tuberculosis has shown a speedy worldwide spread. The incidence of drug-resistant Mycobacterium tuberculosis is increasing in almost all industrialized and developing countries. The epidemiology of multiple drug resistance varies in different regions and countries. The aim of this study was to determine the activities of first-line (isoniazid, rifampin, ethambutol and streptomycin) and second-line (kanamycin, para-aminosalicylic acid, ethionamide and capreomycin) antituberculosis drugs on 100 various clinical isolates of M. tuberculosis. Mycobacterium tuberculosis ATCC 27294, ATCC 35838, ATCC 35825 and ATCC 35837 were used for internal quality control. First-line drug resistant strains were isolated from 10 clinical specimens. Six of them …

Contradictory results have been reported from various studies regarding the effect of age on susceptibility to oxidative damage. Using different parameters, we carried out a comparative study on the erythrocytes and erythrocyte membranes of healthy elderly and young adults to determine how resistance to oxidative damage is affected by aging. Thin layer chromatography and polyacrylamide gel electrophoresis under denaturing conditions were used to estimate changes in membrane phospholipids and cytoskeletal proteins, respectively. Our results showed that these components of intact erythrocytes incubated with cumene hydroperoxide (CumOOH), a powerful oxidising agent, remained unchanged in both age groups. However, exposure of erythrocyte …
