The detection of tubazid and saliuzid metabolites in internal organs and biological fluids

Detection of tubaside and saluside metabolites by methanol extraction from homogenized object with subsequent investigation by UV spectrophotometry, microcrystalloscopy, thin-layer chromatography and coloured reaction methods is suggested. Sensitivity for hydrazine, acetylisoniazid was 0.1 mg%, for opianic and isonicotinic acids--0.05 mg%.
