The goal of this study was to determine whether ghrelin increase aromatase gene expressions and estradiol 17-β concentrations in ventromedial (VMH) and lateral hypothalamic area (LH). Forty rats were randomly divided into four groups. Animals in different groups were received either saline, 1, 2 or 4 ng ghrelin into their VMH and LH. After infusion of ghrelin, VMH and LH tissue were separated and homogenized. Homogenized sample were assayed for aromatase gene expression b...

The goal of this study was to determine whether orexin affects GnRH and LH secretions in the prepubertal rats fed normal or restricted diets. Forty prepubertal rats were randomly divided into 4 groups. Animals in groups 1 and 2 were fed normal and animals in groups 3 and 4 were fed restricted diet for 10 days. After 10 days, animals in groups 1 and 3 received infusions of 1 ug orexin and groups 2 and 4 received infusions of 2 ug orexin into their third ventricle. Blood samples...

The goal of this study was to determine whether ghrelin affect the mean plasma concentrations of Luteinizing hormone, insulin and glucose in the male goat. Twenty male goat were randomly divided into 5 groups. Each group received daily intravenous injection of either 0.1, 0.2, 0.4, 0.8 or 1.6 ug ghrelin/Kg BW. Blood samples were collected from jugular vein every 30 minutes from 6 hours befor till 6 hours after injection of ghrelin. Samples were assayed for plasma LH, INS and g...

The goal of this study was to determine whether ghrelin increase the mean plasma concentration of thyroxine (T4), triiodothyronine (T3), growth hormone (GH), milk amount and constituents in the dairy goats. Animals were anesthetized throughout the surgery for stereotaxic methods and jugular wein cannulations. Nine goats were randomly divide into 3 groups. Each group received daily infusion of either 1 or 2 or 4 ug gherlin for 7 days into their third ventricle. Blood samples we...

Effect of GABA agonist on mean concentrations of growth hormone, thyroxine, triiodothyronine in the womenH Khazali, University of Tarbiat Modarres, Tehran, IranThe goal of this study was to determine whether injections ofGABA agonist increase the plasma concentration of thyroxine (T4) ,triiodothyronine (T3)and growth hormone (GH) in the women. Subgects were randomly divide into 4 groups...

The goal of this study was to determine whether injections of serotonin increase the plasma concentration of thyroxine (T4) , triiodothyronine (T3), growth hormone (GH), milk amount and constituents in the cows. sixty cows were randomly divide into 4 groups. Each group received daily injections of either saline or 1, 2, 4 milligrams serotonin per Kg for 15 days. Blood samples were collected daily on day 3 before injections untill 3 days after the last injection . Samples were ...

The goal of this study was to determine whether injections of bombesin increase the plasma concentration of thyroxine (T4) , triiodothyronine (T3), growth hormone (GH), milk amount and constituents in the cows. sixty cows were randomly divide into 4 groups. Each group received daily injections of either saline or 1, 2, 4 milligrams bombesinper kilogram for 15 days. Blood samples were collected daily on day 3 before injections untill 3 days after the last injection . Samples we...

The goal of this study was to determine whether galanin increase aromataze gene expressions and estradiol 17-β concentrations in ventromedial (VMH) and lateral hypothalamic area (LH). Forty rats were randomly divided into four groups. Animals in different groups were received either saline, 1, 2 or 4 ng galanin into their VMH and LH. After infusion of galanin, VMH and LH tissue were separated and homogenized. Homogenized sample were assayed for aromataze gene expression b...
