The effects of testosterone on the mice pinealocytes: a quantitative study.

abstract：:Vitellogenic oocytes from the cockroach Blattella germanica were dissected free of the surrounding follicle cell layer. The continued presence of a resting potential indicated that the defolliculated oocytes remained viable. In other experiments, lysozyme was injected into last nymphal instars; scanning electron micro...
