Effects of bromocriptine and sulpiride were observed on encoding and retrieval of spatial memory in Wistar rats using Hebb-Williams complex maze. Rat was placed in entry chamber and allowed to reach reward chamber. Ten trials were given each day per rat for 3 consecutive days. Within-day encoding score indicative of learning and between-day retrieval score indicative of memory were calculated. ...

Problem statement: Our previous research has shown that mitochondrial ATPase may have a role in the action of dopaminergic D2 receptors. It is therefore, thought of interest to investigate the effect of bromocriptine, sulpiride or their combination on the mitochondrial and microsomal ouabain sensitive and ouabain insensitive Na/K-ATPase in the liver of rats. Approach: In vivo treatment was carr...

Short-term and long-term effects of bromocriptine mesylate (10 mg/kg i.p.) on cyclic AMP contents of the liver and some endocrine glands have been investigated in the presence and absence of sulpiride (10 mg/kg i.p.). Results revealed that bromocriptine caused significant elevations in the cyclic AMP contents of the liver and reduction in its adrenocortical content. Bromocriptine effect on the ...

Problem statement: The literature is reviewed and supports a strong anecdotal relationship between bromocriptine use and psychosis. It is well known that any interference with brain amino acid levels is likely to lead to disorder. Our previous research has shown that bromocriptine produced significant changes in the heart and kidneys amino acid contents. It has been confirmed that the brain ami...

introduction: dopamine is one member of catecholamine, which has a crusial role in the regulation of feeding behavior. the peripheral injection of dopamine agonistssuch as bromocriptine causes anorexia. the aim of this study is to show how this drugacts. the reason for this selection is due to its importance in the regulation of food intake. materials & methods: sixty three adult male rats (280...

Cyclic GMP contents of the thyroid gland and ovary were significantly increased in response to single and multiple treatments of bromocriptine, an effect which was antagonized by sulpiride. Liver and adrenocortical cyclic GMP levels have not been changed by bromocriptine although sulpiride alone induced a significant reduction. The data may indicate the presence of D2 receptors in ovary and thy...

To test the hypothesis that prolactin mediates the increase in seminal volumes induced by sexual stimulation in stallions, semen was collected from six stallions every other day for 26 d. The last eight collection days were treatment days. For each stallion, four treatments were randomly assigned to the first four of the eight treatment collection days, and then repeated in reverse order on the...

introduction: the protective and antisecretory effects of dopamine agonists on the stomach have been already reported, but the effect of bromocriptine (d2 dopamine agonist) on histamine stimulated gastric acid secretion (gas) needs to be investigated. methods: for gastric sampling, animals were anesthetized and a polyethylen tube was introduced into the stomach through esophagus. a cannula was ...
