Many attempts have been made in the past to discover an ideal treatment for typhoid fever. The first promising attempt in this direction was made by McSweeney in 1946 who published reports of 5 cases of typhoid fever treated with large doses of penicillin and sulphathiazole (McSweeney, 1946). Earlier in the same year Bigger (1946) had observed that the growth of Salmonella typhi in cultures was...

A study was made of the effect of 0.05 and 0.5 N solutions of 20 different chemicals on the activity of purified PR8 influenza virus in 0.1 M phosphate buffer. It was found by tests in chick embryos and in mice that virus activity was destroyed by strong oxidizing agents such as iodine, by salts of heavy metals, by mercurochrome, by formaldehyde, and by the detergents phemerol, roccal, and sodi...

Antitubercular activity of Sulfathiazole Derivitives series were subjected to Quantitative Structure Activity Relationship (QSAR) Analysis with an attempt to derive and understand a correlation between the Biologically Activity as dependent variable and various descriptors as independent variables. QSAR models generated using 28 compounds. Several statistical regression expressions were obtaine...

It is now well established that para-aminobenzoic acid inhibits the action of sulfonamides on bacteria in vitro and in vivo .(Rubbo and Gillespie, 1940; Selbie, 1940; Woods, 1940). Wiedling (1941) found that para-aminobenzoic acid produced an inhibition of the effect of sulfanilamide, sulfapyridine and sulfathiazole on the fresh water diatom Nitzschia palea var. debilis. Experiments published b...

It has been recently reported that catalytic quantities of crystalline catalase, in the presence of hydrogen peroxide, can rapidly oxidize a variety of molecules larger than hydrogen peroxide and aliphatic alcohols (1). The qualitative experiments have shown that oc-naphthol and p-phenylenediamine are condensed by oxidative coupling to indophenol purple; p-aminobenzoic acid, sulfathiazole, adre...

Multidrug-resistant Vibrio cholerae O1 El Tor strains isolated during the 1994 outbreak of cholera in Albania and Italy were characterized for the molecular basis of antibiotic resistance. All strains were found to be resistant to tetracycline, streptomycin, spectinomycin, trimethoprim, sulfathiazole, and the vibriostatic compound O/129 (2,4-diamino-6,7-diisopropylteridine). Resistance genes we...

Studies previously reported on the mode of action of sulfonamides on bacteria showed that the inhibition of respiratory enzymes of the bacteria caused a proportional inhibition of the growth of Streptococcus pyogenes and pneumococcus, type I. This conclusion was based on simultaneous measurements, at various time intervals, of the increase in the number of bacteria (and the mg of bacterial nitr...

As constantes de dissociação de sete sulfonamidas antibióticas, sulfadiazina, sulfatiazol, sulfamerazina, sulfametazina, sulfamonometoxina, sulfadoxina e sulfametoxazol, foram determinadas em diferentes misturas binárias acetonitrila-água (15, 30, 40, 50% (v/v)) usando cromatografia líquida de fase reversa. Um método usando espectros de absorbância no máximo dos picos cromatográficos previament...

A Muslim lady, 60 years old, was given ' cibazol' for lupus erythematosus 2 tablets three times a day. In the same evening she developed itching all over the body, more marked on the scalp, face, forearms and hands. These parts became red and slightly swollen, and her eyes became congested with much watering and swelling of the eyelids. This condition subsided on adrenalin injection, but reappe...
