Abstract

Immunoreactive arginine-vasopressin (IR-AVP) was measured in various hypothalamic and extrahypothalamic nuclei of male Wistar rats immediately after the 24 h retention test of a passive avoidance response. IR-AVP concentrations in paraventricular, suprachiasmatic and lateral septal nuclei were significantly decreased in comparison with the non-shocked rats, while IR-AVP was increased in the central amygdala nucleus, subfornical organ and locus coeruleus. No significant differences in IR-AVP levels were found in the habenular and periventricular hypothalamic nucleus, organum vasculosum of lamina terminalis and medial and dorsal raphe nucleus.

摘要

在对雄性Wistar大鼠进行被动回避反应的24小时记忆测试后，立即测定其各种下丘脑和下丘脑外核团中的免疫反应性精氨酸加压素（IR-AVP）。与未受电击的大鼠相比，室旁核、视交叉上核和外侧隔核中的IR-AVP浓度显著降低，而中央杏仁核、穹窿下器官和蓝斑中的IR-AVP则升高。在缰核、下丘脑室周核、终板血管器以及中缝背核和中缝内侧核中，未发现IR-AVP水平有显著差异。
