Physical exercise and 5-hydroxytryptophan, a precursor for serotonin synthesis, reduce penicillin-induced epileptiform activity.

Aim: Previous studies have shown that 5- hydroxytryptophan (5-HTP) and exercise play an important role in the synthesis of serotonin independently. The effects of the treadmill exercise and 5- hydroxytryptophan (5-HTP) on seizure mechanisms created by epileptiform activity with penicillin model were investigated in rats.

Method: A total of 28 male albino Wistar rats were randomly divided into four groups: exercise (Ex), Control (Cnt), 5-hydroxytryptophan (5htp) and 5-hydroxytryptophan + exercise (5htpEx) groups.

The effects of moderate running exercise and L-tyrosine on penicillin-induced epileptiform activity in rats.

Regular exercise and amino acid supplementation, popular approaches toward the reduction of epileptic seizures, have been extensively researched. This study was conducted to evaluate the effects of treadmill exercise and L-tyrosine treatment on the frequency and amplitude of epileptiform activity in rats. A total of 32 male albino Wistar rats were randomly divided into four groups: control, exercise, L-tyrosine, and exercise + L-tyrosine.

A new oxidative stress indicator: Effect of 5-hydroxytryptophan on thiol-disulfide homeostasis in exercise.

Objectives: The aim of the present study was to evaluate the relationship between exercise and both 5-hydroxytryptophan and oxidative stress using thiol-disulfide homeostasis via what is likely a novel biomarker.

Methods: Male albino Wistar rats (n = 32) were randomly divided into four groups as follows: control, exercise group, 5-hydroxytryptophan group (5H), and 5-HTP + exercise group (5Hex). Exercise and 5-HTP administration (25mg/kg per d) were performed 5d/wk for 10 wk.

A novel biomarker explaining the role of oxidative stress in exercise and l-tyrosine supplementation: thiol/disulphide homeostasis.

The present study aimed to evaluate the relationship between exercise and both l-tyrosine and oxidative stress using thiol/disulphide homeostasis via a novel biomarker in rats. Following the completion of the exercise and l-tyrosine protocol, serum total thiol, native thiol, and disulphide concentrations were determined using a novel automated measurement method. Compared with the control group, serum dynamic disulphide levels were significantly lower in the E group (116.
