The Hormones Of Pregnancy Alter Somal Size In The Medial Preoptic Area Of The Rat Brain, Lori A. Keyser May 1995

The Hormones Of Pregnancy Alter Somal Size In The Medial Preoptic Area Of The Rat Brain, Lori A. Keyser

Master's Theses

Formerly non-responsive females will display maternal behavior (MB) following pregnancy and parturition. The behavioral alterations are believed to occur in response to hormonal changes that accompany pregnancy. The medical pre optic area (MPOA) regulates hormone-induced MB. The current study examined neuronal changes which might account for the modified behavior. Twenty adult female Sprague-Dawley rats were assigned a hormone condition: ovariectomized (OVX), ovariectomized/hormone-treated (P+E2), intact diestrus (DI), or pregnant (PREG). Animals were killed, and their brains fixed in Golgi-Cox solution. Somata of the MPOA and related cortex were measured in each group using a Bioquant imaging system. Pregnant females …


The Effect Of Progesterone On Food And Water Intake And Weight In The Adult Male Rats After Stomach Loads Of Hypertonic Saline, Michael D. Smith Jan 1973

The Effect Of Progesterone On Food And Water Intake And Weight In The Adult Male Rats After Stomach Loads Of Hypertonic Saline, Michael D. Smith

Master's Theses

Eight adult male albino rats were randomly assigned to each treatment condition of progesterone injections (0,10,40, and ·100 mg/kg/day dissolved in Bee of sesame seed oil), and all 2s received a hypertonic NaCl stomach loading. A control group for procedural effects was given injections of sesame seed oil alone and isotonic NaCl stomach loads. The dependent variables were body weight, food intake and water intake. Single factor analyses of covariance revealed a significant difference between the 0 mg progesterone group and the control group for food and water intake but not weight. No significant differences were found in food and …
