【摘要】 发现家蚕脑中央群神经分泌细胞中的A细胞的神经分泌物存在于家蚕一切化性品种的幼虫、蛹、成虫的各个发育阶段。但其数量在不同化性品种中存在着明显差异,有滞育多化性农42、无滞育多化性白皮淡的脑中央群A细胞中的神经分泌物,明显多于一化性罗尼3号和二化性苏5。查明中央群,侧群的B细胞也存在于家蚕不同化性品种中。第一次指出B细胞中也存在液泡。系统调查了A、B两种分秘细胞以及A细胞中的液泡在家蚕中最早出现的时期及存在期等。并对神经分泌细胞在各个时期的生长规律进行了调查。更多还原

【Abstract】 The neurosecretion from "A "cells in silkworm middle neurosecretory cells (MNSC)was found to exist in every developmental stage,such as:larva, pupa and adult, of silkworm varieties with various voltines. Nevertheless, the quantities of secretion among varied voltine races were obviously different. The secretions from multivoltine races,the diapause "Nong 42" and the non-diapause "Bai Pi Dan "were distinctly more than those from the univoltine "Luo Ni 3" and the bivoltine "Su 5". The "B"cells of MNSC and lateral neurosecretory cells (LNSC)were ascertained to exist in varied voltine silkworm races either. Furthermore, vacuole was observed to appear in "B" cell for the first time. "A","B" secretory cells and the earliest period and duration of vacuole appearing in "A"cells were systematically investigated in theis paper, and the growth pattern of neurosecretory cells during every stage was also surveyed.更多还原
