A study of the Effect of Some Antimicrobials against Various Species of Leishmania (In Vitro Study)

Abstract:

Clindamycin LD50 value against L.donovani promastigotes (1.07mg/ml) was more potent than control in opposite axenic and intramacrophage amastigotes (0.07 and 0.15 mg/ml) was less potent than control respectively, against L.major promastigotes, axenic and intramacrophage amastigotes (1.0, 0.015 and 0.64 mg/ml) was less potent than control respectively and against L.tropica promastigotes, axenic and intramacrophage amastigotes (0.63, 0.21 and 0.53 mg/ml) was less potent than control respectively.

Preparation of some Organic Compounds containHetero- atoms as Corrosion Inhibiters forMild Steel in Acidic Media.

Abstract:

1- This work involves preparation of some organic compounds contain hetero-atoms, that starting from (E)-2-benzylidenehydrazinecarbothioamide[1]to (E)-5-(2-chloroethylthio)-N-(1-phenylethylidene)-1,3,4-thiadiazol-2-amine [21],are summarized below: - First set of organic compounds was prepared in one step by a condensation reaction between the carbonyl group of aldehydes or ketones and the amino group ofThiosemicarbazide derivatives to produce the compounds: [1]- (E)-2-benzylidenehydrazinecarbothioamide.

Separation of isomeric hydrocarbons by Gas Chromatography using Liquid Crystalline Materials as Stationary Phases

Abstract:

The synthesized compounds were characterized using FTIR, 1HNMR 13CNMR, EI-Mass spectroscopy and CHN analysis. The liquid crystalline properties of the prepared compounds which were verified using differential scanning calorimete (DSC) and hot-stage polarizing optical microscope (POM) were discussed. The
