arcuate nucleus
9.Effect of neonatal administration of monosodium glutamate on the immunoreactivity of adrenocorticotrepic hormone(ACTH) and corticotropin-releasing factor(CRF)neurones in the mature rat hypothalamus have been studied by the PAP and the immuno-fluoreseent methods, the result showed that MSG selectively damaged ACTH neurons in the hypothalamic arcuate nucleus and CRF immunoreactive terminals in the median eminence.
10.Using radioimmunoassay the contents of EOP of different nuclei were measured at different times after injecting IL-2 into the lateral ventricle of rats. The results suggested that the analgesic effect of IL-2 may be related to β-EP and LEK in arcuate hypothalamic nucleus, paraventricular hypothalamic nucleus and locus ceruleus.
