AB S T R A C T Bronchoalveolar lavage (BAL) fluid was obtained from 24 sequentially studied patients with adult respiratory distress syndrome (ARDS) for assessment of potential activating and mediating factors. Proteolytic activity of the fluids was observed by measuring cleavage of radiolabeled proteins of the contact (Hageman factor) and complement systems. Proteolytic activity was observed i...

conclusions se supplementation can increase plasma se concentration and rbc gsh-pxs activity in patients with different stages of ckd. background plasma selenium (se) concentration and glutathione peroxidase (gsh-pxs) enzyme activity of the patients with chronic kidney disease (ckd) are usually lower than healthy individuals; however, the effect of se supplementation on the gsh-pxs activity in ...

Incubation of rat hepatocytes with epinephrine inhibited alanine aminotransferase (ALT) (80%) and aspartate aminotransferase (AST) (53%) activities with no effect on lactate dehydrogenase (LDH) activity. Injection of epinephrine caused a progressive increase with time in hepatic LDH activity, being 52% at 24 h. Preinjection with propranolol eliminated the hormone effect and caused further ...

Several mammalian enzymes are anchored to the outer surface of plasma membrane by a covalently attached glycosyl-phosphatidylinisitol (GPI) structure. These include acetylcholinesterase, alkalinee phosphatase and 5´-nucleotidase. Recently, it has been reported that these membrane enzymes can be solubilized into the serum by GPI-dependent PLD, under various medical disturbances such as cancer an...

A method for the ultrastructural localization of acyltransferase enzymes involved in phospholipid metabolism has been applied to the developing rat trigeminal nerve. Determination of acyltransferase levels in the nerve indicated that a peak of activity occurs at the 8th day after birth with gradual declines of activity up to 15 days. Morphological surveys and determinations of cholesterol level...

Amine oxidases that occur in the plasma of mammals have been intensively studied in recent years (l-8). The ability of human plasma and serum to convert benzylamine to benzaldehyde has recently been demonstrated (9). Evidence has been presented to show that this enzymatic activity is different from other human plasma enzymes that catalyze the oxidation of amines (i.e. ceruloplasmin and diamine ...

Abstract Essential oils (EOs) are complex mixtures of compounds derived from plants that exhibit antimicrobial activity. Several studies have demonstrated their antifungal activity in food matrices or vitro via vapor phase direct addition. Recently, researchers focusing on elucidating the target site mechanism action various EOs. Past research has suggested evidence how EOs act fungal cells ass...
