In contrast, the traditional Chinese Medi- cine remedy Wen Dan Tang reduces insomnia-related anxiety, which may perhaps correspond to changes in the brain-gut axis. This suggests a possible relationship between Wen Dan Tan^s pharmacological mechanism and the brain-gut axis. Based on this hypothesis, a sleep-deprived rat model was induced and Wen Dan Tang was administered using oral gavage during model es- tablishment. Wen Dan Tang significantly reduced insomnia-related anxiety and prevented Ghrelin level decreases following sleep deprivation, especially in the hypothalamus. Increased expression of Ghrelin receptor mRNA in the hypothalamus was also observed, suggesting that reduced anxi- ety may be a result of Wen Dan Tan＇s regulation of Ghrelin-Ghrelin receptors.展开更多

This study aimed to investigate the effects of Dan-shao-hua-xian, a preparation of traditional Chinese medicine, on the expression of PPAR-gamma and NF-kappa B in the fibrotic livers of rats. METHODS: Seventy Wistar rats were randomly divided into 4 groups: treatment (model, 8 weeks+treatment, 8 weeks; group A), natural recovery (model, 8 weeks+ saline, 8 weeks; group B), model (model only, 8 weeks; group Q, and control (normal, untreated, 16 weeks; group D). Each group consisted of 20 rats (except for group D, which had 10). Fibrotic liver models were induced in rats by subcutaneous injection of CCI4, oral administration of alcohol and a high-lipid/low-protein diet for 8 weeks. After the models were established, the rats in group A were orally given Dan-shao-hua-xian capsules daily for another 8 weeks. Then, the liver indices serum hyaluronic acid (HA), tumor necrosis factor-alpha (TNF-alpha) and alanine aminotransferase (ALT) were measured. The degree of hepatic fibrosis was evaluated by optical microscopy. Hydroxyproline (Hyp) in the liver tissue was determined. The expression of PPAR-gamma was detected by immunohistochemical techniques. The protein levels of PPAR-gamma and NF-kappa B were determined by Western blotting. RESULTS: The concentrations of serum HA, TNF-alpha and Hyp in group C increased compared with group D (P<0.05), and they decreased in group A compared with group C (P<0.05). The expression of PPAR-gamma in group C decreased compared with group D (P<0.05), and it increased in group A compared with groups B and C (P<0.05). Similarly, Western blotting showed that the expression of PPAR-gamma in group C decreased compared with group D, and it increased in group A compared with group C. The expression of NF-kappa B increased in group C compared with group D (P<0.05), and it decreased in group A compared with group C (P<0.05). CONCLUSION: Dan-shao-hua-xian capsules enhance the expression of PPAR-gamma but decrease that of TNF-alpha and NF-kappa B in the liver tissues of CCI4-induced hepatic fibrotic rats. These effects may play a role in its activity in treating hepatic fibrosis.展开更多
