Uridine diphosphate (UDP) glucuronyltransferase activity in chick liver rises at hatching from near zero to adult levels. This rise will occur prematurely in embryo liver during organ culture. Increase in enzyme activity during organ culture differs with embryo age: in liver from 11-day old embryos it ceases at adult values; in liver from 5-day old embryos it continues to much higher-than-adult...

an experiment was conducted to examine the effect of different levels of extruded soybean and enzyme on broiler performance. in a completely randomized design with 2×3 factorial arrangement, 480 one day-old, ross broiler chickens were divided into 40 groups, 12 chicks per pen. treatments were consisting of combination of four levels of extruded soybean (0.0, 5.0, 10.0 and 15.0 %) and two levels...

objective(s) phosphatidate phosphohydrolase (pap) catalyzes the dephosphorylation of phosphatidic acid to yield pi and  diacylglycerol. two different forms of pap in rat hepatocyte have been reported. pap1 is located in cytosolic and microsomal fractions and participates in the synthesis of triacylglycerols, phosphatidylcholine, and phosphatidylethanolamine, whereas the other form of phosphatid...

Rat liver malic enzyme (EC 1.1.1.40) was purified from livers of rats fasted and refed a high sucrose diet containing 1% desiccated thyroid powder. The purification was accomplished by a six-step procedure. The specific activity of the purified enzyme was increased 181-fold above that of the initial high speed supernatant of liver extracts. Slight additional purification of malic enzyme was ach...

Background: Angiotensin converting enzyme (ACE) 2 is a recently identified homologue of ACE that may counterregulate the actions of angiotensin (Ang) II by facilitating its breakdown to Ang 1–7. The reninangiotensin system (RAS) has been implicated in the pathogenesis of cirrhosis but the role of ACE2 in liver disease is not known. Aims: This study examined the effects of liver injury on ACE2 e...

The aim of the present study was to characterize the acyl-coenzyme A: cholesterol acyltransferase (ACAT) activity in human liver microsomes. Liver biopsies were obtained from patients undergoing elective cholecystectomy under highly standardized conditions. In 34 patients the enzyme activity of the microsomal fraction averaged 6.6 +/- 0.7 (mean +/- SEM) pmol.min-1.mg protein-1 in the absence of...

Introduction In this study, we examined the effects of the antibiotics levofloxacin on the liver as well as its devastating effects which are ensued from its over-prescription. Levofloxacin serves as one of the antibiotics of genitourinary system and inferior respiratory system. Since liver is the foremost organ that receives all the materials absorbed by intestine through the portal vein, an...
