Objective:To investigate the effect of Buchang Naoxintong(NXT) on neuropeptide in focal stroke rats and elucidate the mechanisms.Methods:The content of endothelin(ET) and calcitonin gene related peptide(CGRP) in plasma and hypothalamus was measured via radioimmunoassay in both SD rats and spontaneous hypertension rats(SHR) with middle cerebral artery infarction.Results:Oral treatment with NXT counteracted both the decrease of CGRP and rise of NT in plasma during 24 hours after in farction and increased CGRP level in ischemic region in SHR.Conclusion:NXT increases CGRP level in both plasma and hypothalamus
and inhibits the increase of plasma NT in the early phase of stroke
no action on neuropeptide in the late phase of stroke was observed.
