Inhibiting Effects of Theanine on by EEG in the Rat CaffeineStimulation Evaluated
نویسندگان
چکیده
troencephalography (EEG) in rats. First, the stimulatory action by caffeine i.y. administratlon at a level higher than 5"mollkg (O.970 mg!kg) b.w. was shown by means of brain wave analysis, and this level was suggested as the minim"m dese of caffeine as a stimulant. Next, the stimulatory effects of caffeine were inhibited by an i.v. administration of theanine at a level higher than 5pmol!kg (O.781mg!kg) b.w., and the results suggested that theanine has an antagonistic effect

Inhibition by theanine of binding of [3H]AMPA, [3H]kainate, and [3H]MDL 105,519 to glutamate receptors.
In an investigation of the mechanisms of the neuroprotective effects of theanine (gamma-glutamylethylamide) in brain ischemia, inhibition by theanine of the binding of [3H](RS)-alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA), [3H]kainate, and [3H](E)-3-(2-phenyl-2-carboxyethenyl)-4,6-dichloro-1-H-indole-2-carboxylic acid (MDL 105,519) to glutamate receptors was studied in terms ...

متن کاملAnxiolytic effects of L-theanine--a component of green tea--when combined with midazolam, in the male Sprague-Dawley rat.
The purpose of the study was to investigate the anxiolytic effects of L-theanine and its potential interaction with the GABAA receptor in Sprague-Dawley rats. L-theanine is a major component of green tea, which has traditionally been used as an herbal remedy in the treatment of many medical conditions, including anxiety. Herbals and supplements and their potential interactions perioperatively a...
متن کاملAlteration of Mevalonate Pathway in Rat Splenic Lymphocytes: Possible Role in Cytokines Secretion Regulated by L-Theanine
L-Theanine is a nonprotein amino acid in tea, and its immunomodulatory function has been confirmed. This study aimed to investigate the effect of L-theanine addition on cytokines secretion in rat splenic lymphocytes and explore its potential immunomodulatory effects on the mevalonate biosynthetic pathway. Our results showed that L-theanine treatment did not influence the proliferation and divis...
متن کاملEffects of ketotifen on oxytocin-induced contraction in the isolated rat uterus
Preterm labor is one of the major causes of neonatal mortality and morbidity. Despite significant improvement in care for premature neonates, the most suitable and inexpensive treatment is prevention of preterm labor by inhibiting uterine contractions. The aim of this research is to obtain scientific evidence for the relaxant effect of ketotifen on the rat uterus and to provide the preclinica...
