Ablation of the hypothalamic arcuate-median eminence region reduces the concentration of vasoactive intestinal peptide in the anterior pituitary gland of male rats.

This study was designed to determine the influence of the hypothalamus on the content of vasoactive intestinal peptide (VIP) in the anterior pituitary. Disruption of the hypothalamic-pituitary connection was performed by ablating the arcuate-median…

Daily exercise attenuates the sympathetic component of the arterial baroreflex control of heart rate.

The influence of daily spontaneous running (DSR) on the sympathetic (SC) and parasympathetic components of the arterial baroreflex control of heart rate (HR) was examined in 16 female Long Evans rats [8 sedentary (SED) and 8 DSR]. After

Daily spontaneous running alters behavioral and neurochemical indexes of nigrostriatal function.

Behavioral and neurochemical indexes of nigrostriatal dopaminergic function were compared between sedentary control rats (n = 12) and daily spontaneous running (DSR) male rats (n = 10). Nine weeks of DSR did not significantly alter body, heart,…

Laparoscopic-assisted vaginal hysterectomy for uteri weighing 1000 grams or more.

INTRODUCTION: Prospective randomized trials have proven the benefits of laparoscopic-assisted vaginal hysterectomy (LAVH) compared with abdominal hysterectomy. The purpose of this study was to evaluate the safety and efficacy of LAVH performed for…

Sex steroid induction of gallstones in the male Syrian hamster.

Light (LM), transmission (TEM) and scanning (SEM) electron microscopic techniques were used to characterize morphologic changes induced in the gallbladder of Syrian hamsters following a one-month estradiol (E) and estradiol + medroxyprogesterone…

Gallstones induced by sex steroids in the female Syrian hamster: duration effects.

Scanning (SEM), and transmission (TEM) electron microscopy were used and correlated to morphologically characterize changes induced in the gallbladder epithelium of female Syrian hamster in response to treatments with estradiol (E) alone, and…

Morphological aspects of female Syrian hamster gallbladder induced by one-month sex steroid treatment.

Light (LM), transmission (TEM), and scanning (SEM) electron microscopy were used to characterize morphological changes induced in the gallbladder epithelium of female Syrian hamsters in response to one-month estradiol alone (E) and estradiol with…

Daily spontaneous running did not alter vagal afferent reactivity.

Exercise training alters the cardiopulmonary baroreflex regulation of the circulation; however, the mechanisms responsible are unknown. One possibility is an enhanced afferent response to cardiopulmonary stimulation. We therefore tested the…
