Aqueous Bridelia ferruginea stem bark transaminase activities in albino rats

The major objective of this study was to evaluate the transaminase activities of albino rats fed with aqueous extract of Bridelia ferruginea stem bark. Sixteen (16) albino rats with weight ranging between 100-190 g were used. The rats were divided into four groups; with group four as the control group.

Properties of arginase from gut of adult cockroach (Periplaneta americana)

Arginase (EC 3.5.3.1) catalyzes the hydrolysis of arginine to ornithine and urea. The role of arginase in insect has been seen in the growth of insect at various stages of development and energy requirement for flight. Here, we reported the properties of arginase in the gut of adult cockroach, Periplaneta americana. The enzyme was partially purified with ammonium sulphate precipitation and affinity chromatography. The...
