Aim To investigate the effects of Shaoqiduogan(SQDG)on cellular immunity in mice with delayed-type hypersensitivity(DTH). Methods DTH model induced by 2, 4-dinitrochlorobenzene(DNCB)and cyclophosphamide(Cy)suppressed and potentiated DTH model were used. SQDG(30, 60 and 120 mg ? kg-1)were given intragastrically(ig)once daily for 7 consecutive days. Concanavalin A(Con A)-induced T cells proliferation was measured by MTT assay. The activity of IL-2 in culture supernatants of Con A-induced T cells proliferation was measured by testing its ability to support the proliferation of Con A stimulated thymocytes which was detected by MTT assay. Results In mice with DTH, SQDG(120 mg?kg-1)reduced ear swelling, thymus index, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of Con A-induced T cells proliferation. The suppression and potentiation of DTH in mice were induced by given an intraperitoneal(ip)injection of Cy at the dose of 150mg?kg-1 on primary sensitization day and 250 mg?kg-1 three days before primary sensitization. SQDG(60 and 120 mg?kg-1)upregulated ear swelling, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of T cells from mice with Cy-suppressed DTH; and downregulated levels of the aforementioned indexes in mice with Cy-potentiated DTH. Conclusion SQDG possesses a dual modulatory effect on cellular immunity in mice.

Objective To investigate the effects of Xuebijing injection on the production of ICAM-1 and its counterreceptor(LFA-1)in ANP of rats at different time points.Methods ANP was induced by multiple points in- jection of 5% chenodeoxycholic acid into the pancreas,followed by ligation of pancreatic duct.Expressions of ICAM- 1 at different time points were assessed by immunohistochemistry method,the expressions of LAF-1 on neutrophils at different time points were detected by flow cytometer.The effect of Xuebijing injection was also evaluated by de- tecting the output of ascitic fluid,amylase level and histological changes in pancreas and lungs.Results The expres- sions of ICAM-1 in pancreas and lung of Xuebijing injection group decreased significantly than those in ANP group at most time points during the research period(P

Lactate and succinate were produced by Corynebacterium acetoacidophilum from glucose under oxygen deprivation conditions. To construct knockout mutant, lactate dehydrogenase gene (ldh) of C. acetoacidophilum was deleted by double-crossover chromosome replacement with sacB gene. Comparing with the wild strain ATCC13870, ldhA-deficent mutant produced no lactate with glucose consumption rate decreased by 29.3%, while succinate and acetate concentrations were increased by 45.6% and 182%, respectively. Moreover, the NADH/NAD+ rate was less than 1 (about 0.7), and the activities of phosphoenolpyruvate carboxylase and acetate kinase of the ldhA-deficent mutant were enhanced by 84% and 12 times, respectively. Our studies show that succinicate and acetate production pathways are strengthened by blocking lactate synthesis. It also suggests that improving NADH supply and eliminating acetate generation are alternative strategies to get high succinate-producer.
