IN VITRO EFFECT OF HYDROGEN SULFIDE ON THE ACTIVITY OF SOME ENZYMES OF RAT LUNG HOMOGENATE

Abstract

The effect of various concentrations of hydrogen sulfide gas on the activities of rat lung enzymes was tested in vitro using a simple gas bubbling method. Adenosine triphosphatase, acid phosphatase, alkaline phosphatase, glutamic-pyruvic transaminase and glutamic-oxaloacetic transaminase activities were inhibited. Various levels of the gas increased arginase activity while fructose 1, 6 diphosphate aldolase activity remained unaffected.
