Abstract:
Objective: To investigate the changes in common chemical signal molecules of neuroendocrine-immune (NEI) network and intervention of Tongxinluo (TXL, ultramicro-pulverization) of rats under hypoxia qi-asthenia condition. Methods: Forty-five male Wistar rats were randomly assigned to the following groups: control group, qi-asthenia model group and TXL group (n=15). The rats in the former 2 groups were gavaged with CMC-Na (10 ml/ kg) once daily; those in the TXL group were gavaged with TXL (ultramicrot-pulverization) suspended in CMC-Na (10 ml/kg) once daily; After gavage, animals in the qi-asthenia model group and TXL group were placed in a cabin with normal pressure hypoxia (7 h daily, 6 d weekly for 5 weeks). At the end of the experiment, the biological characters of rats were observed and arterial blood gas was analyzed. The serum contents of serotonin (5-HT), norepinephrine (NE), epinephrine (E), dopamine (DA) and IFN-γ and TRH level in the hypothalamus were examined by enzyme linked immunosorbent assay (ELISA); the serum contents of corticosterone (Cort), T3,T4,IL-1β,TNF-α, and corticotropin release hormone(CRH) in the hypothalamus, and adrenocorticotropic hormone/thyroid stimulating hormone(ACTH/TSH) in the hypophysis cerebri were examined using radio-immunity method. Results: Compared with control group, the biological character scores of rats in the qi-asthenia model group were significantly bigher(P
