ABSTRACT
BACKGROUND: Sulongga-4 (SL-4) is a herbal formula used in traditional Mongolian medical clinics for the treatment of peptic ulcers and gastroenteritis, even though its pharmacological mechanism has not been well characterized. AIM: To evaluate the protective effect and identify the mechanisms of action of SL-4 on gastroduodenal ulcer induced by pyloric ligation (PL) in rats. METHODS: PL was performed to induce gastric and duodenal ulcers in rats, which were then treated with oral SL-4 (1.3, 2.6, or 3.9 g/kg per day) for 15 d. PL-induced gastroduodenal ulceration. Therapeutic effects were characterized by pathological and histological evaluations and inflammatory indicators were analyzed by enzyme-linked immunosorbent assay. Microarray analyses were conducted to identify gene expression profiles of gastroduodenal tissue in PL rats with or without SL-4 treatment. The candidate target genes were selected and verified by quantitative reverse transcription polymerase chain reaction (qRT-PCR). RESULTS: SL-4 decreased histopathological features in the PL-induced ulcerated rats. SL-4 significantly (P < 0.05) decreased expression of tumor necrosis factor-α, interleukin (IL)-1ß, IL-6, endotoxin, platelet-activating factor, and increased prostaglandin E2 and epidermal growth factor in ulcer tissue. Microarray analysis was used to identify a panel of candidate target genes for SL-4 acting on PL-induced ulceration. Genes included some complement and coagulation cascade and retinol metabolism pathways that are closely associated with inflammatory responses and gastric mucosal protective mechanisms. qRT-PCR showed that altered expression of the selected genes, such as CYP2b2, UGT2b1, A2m, and MASP1 was consistent with the microarray results. CONCLUSION: SL-4 exerts protective effects against PL-induced gastroduodenal ulcers via reducing inflammatory cytokines and elevating expression of gastric acid inhibitory factors. Downregulation of CYP2b2 and UGT2b1 genes in retinol metabolism and upregulation of A2m and MASP1 genes in the complement and coagulation cascades pathways are possibly involved in SL-4-mediated protection against gastroduodenal ulcer.

Purpose@#To study effect of San Gen talkh medicine and San Gen granule medicine, on healthy rats immune system@*Method@#In this study 32 male healthy Wistar rats were randomly divided into normal group, low dose group of San Gen talkh (SGTLD), high dose group of San gen talkh (SGTHD) and group of San Gen granule (SGG). In normal group rats were administrated 0.2m l/kg saline solution, in San gen talkh groups rats with low dose and high dose were administrated 0.85g/kg, 1.70g/kg San Gen talkh respectively and in San gen granule medicine groups rats 1.3 g/kg San gen granule medicine, once daily for 42 day. By Elisa method measured IL-10, IL-12, IL-17, IFN-γ and TGF-β in blood plasma and spleen tissue of rat.@*Result@#In this experimental result, there was no significantly difference all measured cytokine of blood plasm (P>0.05) between healthy group and all medicine group. In spleen tissue, there was significantly increased IFN-γ (P<0.05) and TGF-β (P<0.05) in SGTHD group and was significantly increased IFN-γ (PO.05), IL-10 (P<0.01)and TGF-β (PO.001) in SGG group compared with normal group.@*Conclusion@#High doses San Gen talkh medicine and San Gen granule medicine can support cellular immune system, humoral immune system on healthy rats.
ABSTRACT
Background@#Trogopterus xanthipes Milne-Edwards (Hadan hailmal) is defecation of Olbo mouse with red and yellow foot in Olbo mouse family. Trogopterus xanthipes Milne-Edwards has bitter and little sweety flavor and cool and sharp quality and it has effects such as to remove hot, to stop pain and to to make urinate etc.@*Purpose@#To summarize chemical compounds, pharmacological effects, clinical usage and ancient source notes of Trogopterus xanthipes Milne-Edwards. @*Method@#Вy analys method to analyzed research articlest and ancient source of Trogopterus xanthipes Milne-Edwards in China Biological Medical Digest Data-base, Chinese Journals Full Text Data-base and ancient sources of Mongolian traditional medicine.@*Results and Conclusions@#Trogopterus xanthipes Milne-Edwards is produced juice from gold, silver, copper, iron, lead and tin on cliff during 4 to 6 months and otherwise Trogopterus xanthipes Milne-Edwards is called defecation of olbo mouse. It has many activity chemical compounds, such as nitrogen compound, volatile compound, Triterpenoid, fatty acid, flavone, and microelement and has many pharmacological effects such as anti gastric ulcer, anti inflammation, anti oxidant, anti cerebral ischemic injury, anti cytotoxicity and to improve immunology. In Mongolian traditional medicine, Trogopterus xanthipes Milne-Edwards mainly used to treat hot disease of stomach, liver and kidney, synovial disease, gout and rheumatism etc with single medicine and compound recipe ingredients of Trogopterus xanthipes Milne-Edwards. In Chinese medicine used to treat disease of digestive system and to stop pain etc.
