Position, shape and cytoarchitecture of the paraventricular nucleus were observed in 30 guinea pigs of both sexes, in serial frontal sections of the hypothalamus stained selectively for neurosecretion content, considering the sex of the animals examined and hypothalamus sides. Three morphological units of the nucleus were distinguished (parts: oral, principal and caudal) and four subunits (zones: medial, lateral, ventral and dorsal) as the basis for cytomorphological analysis. Morphology of PVN neurocytes was evaluated in 12 guinea pigs with regard to nine selected parameters. The results were formulated statistically. Cytomorphological comparisons were done between respective PVN units and subunits, depending on the side of sections in males. The results referring to the principal part of the right PVN in males and females were compared. Heterogeneity of the PVN-forming-cellular populations was revealed. Cytomorphological differences were noted between PVN and SON.
在30只雌雄豚鼠中，观察室旁核的位置、形态和细胞构筑，这些豚鼠的下丘脑连续额状切片经选择性染色以显示神经分泌物质，并考虑所检查动物的性别和下丘脑的两侧。区分出该核的三个形态学单位（部分：嘴侧、主体和尾侧）和四个亚单位（区：内侧、外侧、腹侧和背侧）作为细胞形态学分析的基础。在12只豚鼠中，针对九个选定参数评估室旁核神经细胞的形态。结果进行了统计学处理。根据雄性切片的侧别，对各个室旁核单位和亚单位进行细胞形态学比较。比较了雄性和雌性右室旁核主体部分的结果。揭示了构成室旁核的细胞群体的异质性。注意到室旁核与视上核之间的细胞形态学差异。
