RESUMO
Objective@#The active components and potential targets were predicted and confirmed to explore the possible mechanism of Wenpi decoction on ulcer colitis.@*Methods@#The traditional Chinese medicine integrated pharmacology platform (TCMIP) was used to construct the decoction-target-disease target network, and the key nodes were analyzed and screened. The function and pathway enrichment analysis were conducted to explore the biological processes, which Wenpi decoction may be involved in the treatment of ulcerative colitis.@*Results@#The study showed that there were 455 active ingredients and 3044 targets in Wenpi decoction. The 434 targets and multiple biological processes and metabolic pathways were involved, such as chemokine signaling pathways, estrogen signaling pathway, thyroid hormone signaling pathway, MAPK signaling pathway, and PI3K/Akt signaling pathway. These targets and pathways were consistent with the pathogenesis of ulcerative colitis reported in the literature. In addition, Wenpi decoction was potential to be applied in the treatment of tumor, endocrine and metabolic diseases.@*Conclusions@#This study provided a scientific basis for further studies on the mechanism of Wenpi decoction in the treatment for ulcer colitis.
RESUMO
Objective To explore the influence of the extract of wen-pi-tang on the memory and SOD and MDA of normal mice and cerebral ischemia reperfusion mice.Method The mice were divided into normal group,sham operation group,model group,aqueous extract and alcohol extract of wen-pi-tang (1.0 g/kg,0.5 g/kg,0.25g/kg).Model mice with cerebral ischemia reperfusion were made by blocking bilateral common carotid artery.The influence on memory behavior of normal mice and mice with cerebral ischemia reperfusion were tested by gavage for 10 days with extract of wen-pi-tang through step-down and step-through tests.Then SOD activity and content of the MDA were tested.Result In step-down test,compared with normal group,extract of wen-pi-tang with all doses made normal mice' latency longer,error frequency fewer,with high does clearest (P＜0.05)(latency:(187.17±99.00) s,(270.73±44.73) s,(260.45±63.78) s,error frequency(1.75± 1.71) times,(0.45±0.69) times,(0.75±0.97) times) ;in step-through test,compared with normal group,aqueous extract with high and middle doses and alcohol extract with longe doses could made latency of cerebral ischemia reperfusion mice longer and error frequency fewer (latency(157.15±84.91) s,(250.63±58.98) s,(251.12±78.22) s,(245±84.82) s,error frequency(2.15± 1.22) times,(0.75±0.89) times,(0.75± 1.16) times,(0.625 ±0.92) times) (P＜0.05) ; extract of wen-pi-tang with high and middle does increased SOD activity obviously compared with normal group(P＜0.05),and the content of MDA was obviously lower compared with normal group(P＜0.05,P＜0.01).Conclusion Extracts of wen-pi-tang can improve the memory function of normal mice,and the memory of cerebral ischemia reperfusion mice.The mechanism can be related to the increase of SOD activity and the decrease of the content of MDA.
RESUMO
OBJECTIVES: Wen-pi-tang-Hab-Wu-ling-san (WHW) is an oriental herbal prescription formulated using 14 herbs and has been used to cure chronic renal failure in Korean oriental medicine. In this study, we investigated the anti-diabetic effect of WHW in the streptozotocin-induced diabetic rats. MATERIALS AND METHODS: Diabetes was induced by streptozotocin (STZ, 60 mg/kg, i.p.) in rats. WHW extract (100 mg/kg) was orally dosed once a day for four weeks. The results were compared with standard antidiabetic drug, glibenclamide (3 mg/kg, p.o). RESULTS: Significant decrease in body weight and insulin levels and increase in blood glucose, triglycerides, urea nitrogen (BUN), and creatinine were detected in STZ-induced diabetic rats with disruption and disappearance of pancreatic and kidney cells and decrease in insulin producing beta cells. However, these diabetic changes were significantly inhibited by treatment with WHW extract. In the oral glucose tolerance test, the extract produced a significant decrease in glycemia 60 minutes after the glucose pulse. CONCLUSIONS: Based on these results, we suggest that WHW extract has favorable effects in protecting the STZ-induced hyperglycemia, renal damage, and beta-cell damage in rats.
