In a double-blind clinical trial, 24 patients with advanced chronic liver disease received 1.2 g of nicotinohydroxamic acid daily and 23 patients received 1.5 g of neomycin. Patients receiving nicotinohydroxamic acid showed significant improvement in blood ammonia levels as compared to patients receiving neomycin. Nicotinohydroxamic acid induced some side effects, such as mild diarrhea, constipation and anorexia, but less than in cases of neomycin.
The micromethod technique for the determination of enzyme activities in liver is out lined. It is demonstrated that the micromethod technique is reliable. G lutamic oxaloacetic transaminase, glutamic pyruvic transaminase, alkaline and acid phosphatases, glucose-6-phosphatase, catalase, aldolase and arginase activities in liver and serum were measured in various liver and malignant diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
