Abstract

Somatotrophs (GH cells) were classified immunoelectron microscopically into three types mainly on the basis of the size of secretory granules in the mouse pituitary of ICR strain. Type I cells contained large secretory granules. Type II cells contained both large secretory granules and small secretory granules. Type III cells contained small secretory granules. All three types of GH cells were found from the neonatal ages to adult. The relative proportion of three types did not change with age, and no sex differences in the relative proportion of the cell types were detected. Type I cells predominate in all age groups observed. In 60-day-old male mice percentages of each type were as follows: type I 93.7 ± 0.1%, type II 5.4 ± 0.8%, and type III 0.9.0 ± 0.4% (n = 5), and in 60-day-old female mice type I 95.2 ± 0.1%, type II 2.7 ± 0.5%, and type III 2.1 ± 0.9% (n = 5). The maximum diameters of the large secretory granules increased from 7 to 60 days of age. The small secretory granules similarly increased in size in female mice, but those in male mice did not change. In the diabetic female mice of the nonobese diabetic (NOD) strains, GH cells in diabetic mice became smaller, and the number and size of secretory granules decreased, indicating diminished GH secretion. However, the relative proportion of each subtype of GH cells did not differ irrespective of the occurrence of diabetes.

Abstract

In order to examine the optimal administration period and parameters for male fertility assessment, male rats were subcutaneously administered 0.2, 2 or 20 micrograms/kg of estradiol benzoate (E2B), a known testicular toxicant, for 4 weeks or 9 weeks before mating. After 4 weeks administration, suppression of body weight gain and food consumption, decreases in prostate and seminal vesicle weights, atrophy of Leydig cells, and mature spermatid retention at stages IX, X and XI were observed in the 2 and 20 micrograms/kg groups. In the 20, micrograms/kg group, decreases in epididymides weight and copulation index were also found but the number of sperm and sperm motility were not affected. In the 0.2 micrograms/kg group, no changes were noted in any parameters. After 9 weeks administration, decreases in testis weight and the number and motility of sperm were observed in the 20, micrograms/kg group, in addition to the changes found after 4 weeks administration. These results suggest that detailed histopathological evaluation and determination of accessory sex organ weights are sensitive for evaluating the effects of E2B on male fertility. Results with the 4-weeks treatment were comparable to those with the 9-weeks treatment in terms of these parameters.
