ABSTRACT
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
C-repeat-binding factors (CBFs) are a type of important regulon in stress-related signal transduction pathways that control plant tolerance of abiotic stress. Ammopiptanthus mongolicus is the only evergreen broadleaf shrub in the northwest desert of China. The species shows strong resistance to environmental stress, especially to cold stress. An A. mongolicus CBF1 gene (AmCBF1) was cloned and transformed into tobacco. Expression of AmCBF1 could be detected in A. mongolicus shortly after exposure to low temperature of 4°C. Analysis on ratio of electrolytic leakage, soluble sugar content, free proline content, malondialdehyde (MDA) content and peroxidase (POD) activity before and after cold treatment (4°C) for 24 h indicated AmCBF1 conferred higher cold tolerance to AmCBF1 transgenic tobacco compared with the wild type and empty vector transformed tobacco.
