Abstract: Sex steroids have been shown to have a marked effect on the physiologic activities of the liver and the gastrointestinal tract. We performed autoradiographic studies using [3H]estradiol and [3H]dihydrotestosterone on male and female baboons for the purpose of identifying estrogen or androgen receptors, or both, in the liver, pancreas, stomach, and small and large intestines of baboons. Evidence for the presence of estrogen and androgen receptors was made apparent by high concentrations of silver grains over the nuclei of the cells of these tissues. Androgen receptors were largely confined to the nuclei of the smooth muscle cells of the tunica muscularis of the gut wall and the connective tissue interstitial cells of the liver, pancreas, stomach, and intestines. Estrogen receptors were prominent in the nuclei of the vascular smooth muscle cells in the liver, pancreas, gut, and the majority of the endocrine islet cells. These observations suggest that a variety of different cell types of the liver, pancreas, and gastrointestinal tract contain estrogen and androgen receptors that might modulate their cellular activities and influence several different physiologic processes.
answer:
Sex steroid receptors in the stomach, liver, pancreas, and gastrointestinal tract of the baboon.

question:
Abstract: Sixty-five children viewed by their teachers as hyperactive were evaluated as to whether they would benefit from stimulant medication. All underwent extensive neurodevelopmental and educational testing. Additional information was obtained from school and parent questionnaires and interviews. Children were not placed on medication unless they demonstrated characteristic impulsive, inattentive, and/or overactive behavior in two of three environments (home, school, clinic). Fifty-two children (80%) were not placed on medication. Follow-up was completed in 80 percent, and 93 percent of these children were doing well with nonpharmacologic interventions. Initial comparison of children not placed and placed on medication revealed that age, race, SES, amount of resource help and retention could not distinguish groups. Children placed on medication had difficulties earlier in school (chi 2 = 4.88, p less than 0.05), weren't as delayed academically (chi 2 = 6.30, p less than 0.05) and had less neurodevelopmental disorders (chi 2 = 9.01, p less than 0.01). If a careful psychosocial history does not reveal impulsive, inattentive, and/or hyperactive behavior outside of school, a child should be evaluated to rule out neurodevelopmental and educational problems.
answer:
Pediatric management of nonpervasively "hyperactive" children.

question:
Abstract: Anestrous hamsters exhibit daily afternoon gonadotropin and progesterone surges, but little estrogen secretion. In the first experiment, short day anestrous females were transferred to long days to detect hormonal changes associated with recovery of cyclicity. Morning and afternoon blood samples were taken at increasing durations in long days. Females autopsied at their first vaginal estrus after transfer to long days differed from long day estrous controls only in their lower uterine weights. Some females at all durations exhibited signs of recovery, though they had not yet shown estrus. They did not display afternoon gonadotropin surges and had low circulating progesterone but high estradiol levels, stimulated uteri, and enhanced follicular development. Results of the second and third experiments provided evidence that the daily gonadotropin surges are not the cause per se of anestrus, and that changes in estrogen secretion are essential for the transition to and from anestrus. Phenobarbital blockade of the daily surges in anestrous females did not result in increased follicular growth and estrogen secretion. Furthermore, daily afternoon injections of gonadotropins it appears that the daily surges in anestrous hamsters simply reflect low estradiol levels. It is still not known what signal promotes rapid follicular maturation during the recovery from anestrus. Once initiated, however, this recovery appears to occur within a few days, with a rapid cascade of events. First, follicular development and estrogen secretion resume, and the daily LH surges cease. Then, progesterone levels decline, and an ovulatory surge of gonadotropins is triggered.
answer:
Dynamic pituitary and ovarian changes occurring during the anestrus to estrus transition in the golden hamster.
