Although much has been published about growth of Vibrio cholerae in natural sources of water, little or nothing has been written on its survival in common household water storage containers. This study compared the behaviour of the El Tor and Classical biotypes of V. cholerae in different containers commonly used in Africa for domestic water storage. These(More)
The present invention relates to produce multiple unit particle system (MUPS) of stabilized ramipril pellets, hydrochlorothiazide, diluents, superdisintegrants, and lubricants which produce better dissolution of the system for better bioavailability with improving stability and bioavailability of ramipril. More particularly, the present invention is(More)
Many physicochemical factors affect the survival of Vibrio cholerae in the aquatic environment. An attempt was made to study the combined effect of pH and iron on the survival of V. cholerae in water in a laboratory environment. None of the 6 strains of V. cholerae used survived at pH 5.0; survival of all strains increased with increasing pH. The effect of(More)
In vitro and in vivo studies were conducted to assess the response of cholera toxin (CT) production to increasing iron concentrations in an aquatic environment. Production of CT by seven of eight Vibrio cholerae strains tested, including the Bengal strain (O139), was significantly enhanced in the presence of iron concentrations of 1.0 and 10 g/L. The(More)
In attempt to find new pharmacologically active molecules, we report here the synthesis and in vitro anti-inflammatory activity of various 1-[5-(substituted phenyl)-1-phenyl-4,5dihydro-1H-pyrazol-3-yl]-5-phenyl-1H-tetrazole (IV a-h).The anti-inflammatory activity of title compounds were examined by denaturation of proteins method. All the compounds(More)
Many factors, such as temperature, pH, organic nutrients, types of water storage containers, etc., determine the survival of Vibrio cholerae in water. Since the survival of V. cholerae O1 has been shown to be much longer in metal drums used as household water storage containers than in clay pots and plastic drums, the present study was designed to explore(More)
Eight different derivatives of substituted 5-phenyl-1-(5-substituted phenyl) -4,5-dihydro1H-pyrazol-3-yl)-1H-tetrazole (4a-h) were synthesized by reacting the chalcones with hydrazine hydrate in presence of glacial acetic. The chemical structures were confirmed by means of FT-IR, H-NMR, mass spectra and elemental analysis. The compounds were screened for(More)
