SH 714 (1, 2-alpha-methylene-6-chloro-delta-4, 6-17-alphahydroxyprogesterone
acetate) synthesized by Schering AG is an highly
antiandrogenic, nonestrogenic compound. The present investigation
was undertaken to determine the compound's effect upon the cell
associations of the germinal epithelium in the mature rat. From germinal epithelium for this dosage level of SH 714 was exhibited...
The spermiogenesis of Mytilus edulis (a marine mussel) has
been studied, employing techniques of light and electron microscopy
and cytochemical preparations. The observations trace the development
of the acrosomal complex, the nucleus, the mitochondrial
middle-piece, and the flagellum.
In early spermatids numerous membrane-bounded proacrosomal
vesicles arise from several Golgi complexes...
I. Frozen bovine semen samples were measured by flow cytometry
(FCM) to determine if FCM analyses could be useful for sperm quality
evaluation and prediction of bull fertility. Fluorescent dyes
utilized were acridine orange, to measure sperm nuclear chromatin
heterogeneity by quantifying susceptibility of the chromatin to
denaturation, and rhodamine...
