Effects of L-phenylalanine on acetylcholinesterase, (Na+,K+)-ATPase and Mg2+-ATPase activities in adult rat whole brain and frontal cortex.
The effect of different L-phenylalanine (Phe) concentrations (0.12-12.1 mM) on acetylcholinesterase (AChE), (Na+,K+)-ATPase and Mg2+-ATPase activities was investigated in homogenates of adult rat whole brain and frontal cortex at 37 degrees C. AChE, (Na+,K+)-ATPase and Mg2+-ATPase activities were determined after preincubation with Phe. AChE activity in both tissues showed a decrease up to 18% ...
متن کاملThe role of Na+-K+-ATPase in the basic and rate-dependent properties of isolated perfused rabbit Atrioventricular Node
Introduction: Ouabaine is a well-known atrioventricular (AV) node depressant agent, but its effects on functional properties of the AV node have not been cleared. The aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the AV node. Methods: Selective stimulation protocols were used to quantify independently electrophysiological prop...
متن کاملEffects of L-phenylalanine on acetylcholinesterase and Na+,K+-ATPase activities in suckling rat frontal cortex, hippocampus and hypothalamus.
The effect of different L-phenylalanine (Phe) concentrations (0.12-12.1 mM) on acetylcholinesterase (AChE), (Na+,K+)-ATPase and Mg2+-ATPase activities was evaluated in homogenates of suckling rat frontal cortex, hippocampus and hypothalamus. Phe, at high concentrations, reduced AChE activity in frontal cortex and hippocampus by 18%-20%. On the contrary, the enzyme activity was unaltered in the ...
متن کاملO-10: A Marked Animal-Vegetal Polarity in The Localization of Na+,K+-ATPase Activity and Its Down-Regulation Following Progesterone-Induced Maturation
Background: Polarized cells are key to the process of differentiation. Xenopus oocyte is a polarized cell that has complete blue-print to differentiate 3 germ layers following fertilization, as key determinant molecules (Proteins and RNAs) are asymmetrically localized. The objective of this work was to localize Na+, K+-ATPase activity along animal-vegetal axis of polarized Xenopus oocyte and fo...
متن کاملThe effect of galactose metabolic disorders on rat brain Na+,K+-ATPase activity.
To evaluate the effect of galactose metabolic disorders on the brain Na+,K+-ATPase in suckling rats. Separate preincubations of various concentrations (1-16 mM) of the compounds galactose-1-phosphate (Gal-1-P) and galactitol (galtol) with whole brain homogenates at 37 degrees C for 1 h resulted in a dose dependent inhibition of the enzyme whereas the pure enzyme (from porcine cerebral cortex) w...
