Objective To investigate the effects of Shuangligan and Glycine on Thl/Th2 balancing on severe acute pancreatitis ( SAP) in rats. Methods Thirty-two Wistar rats weighing (260 ± 20) g were randomly divided into sham operation (SO) group, SAP group, SAP + Slg (with the treatment by Shuangligan) group and SAP + Gly (with the treatment by Glycine ) group. Each group included 8 rats, which accepted different treatment according to the experimental design. Changes of plasma level of endotoxin ( ET) and serum amylase (AMY) and the effects of Shuangligan and Glycine on Thl/Th2 ratio at the 24th hour after operation were observed respectively. Results The plasma endotoxin (ET) level ( (0. 67 ±0. 11) EU/ml),proinflammatory cytokine (INF-γ:(8.43 ± 0.86) ng/L, IL-12: (8.26 ± 1.97) ng/L) and Thl/Th2 ratio (0.36 ± 0.07) in SAP group were significantly higher than those in SO group( ET: (0. 44 ±0.07) EU/ml, INF-γ: (3. 80 ±0. 55) ng/L, IL-12: (3. 34 ± 1. 34)ng/L,Thl/Th2 ratio (0. 24 ±0. 05) ) (P <0. 05). Compared with SAP group, SAP + Slg and SAP + Gly group had remarkably decreased plasma ET level ( (0. 57 ± 0. 08,0. 52 ± 0. 04) EU/ml) (P < 0. 05) and the Thl/Th2 ratio reached equilibrium ( SAP + Slg group; (0. 29 ± 0. 04 ), SAP + Gly group: (0. 25 ± 0. 06 )) . Conclusions In the earlier stage of SAP, the rising plasma ET level may cause the overreaction of the cell mediated immune response, which leads to the aggravated damages in tissue cells. Our data indicates that Shuangligan and Glycine can restrain the formation of intestinal endotoxemia and alleviate or prevent the tissue injuries.

AIM: To investigate the effect of LPS on phagocytosis of Kupffer cells in vitro. METHODS: Isolated Kupffer cells were treated with LPS in vitro . The phagocytosis, microfilament, microtubules and apoptosis of Kupffer cells were determined by the beads phagocytosis test, fluorescence staining, fluorometry and flow cytometric analysis. RESULTS: LPS enhances the phagocytosis, actin content, microtubules fluorescence density of Kupffer cells in vitro , while at a large dose or for a long time, it lessened the phagocytosis increasing or phagocytosis, inhibites the microfilament and microtubules expression, and induced apoptosis. CONCLUSION: LPS enhances the phagocytosis of Kupffer cells in vitro , but in large amount, it inhibites the phagocytosis of Kupffer cells, which is probably related to LPS -induced microfilament, microtubules expression changes and apoptosis in Kupffer cells.

AIM: To examine the effects of inhibition of Kupffer cell and splenectomy on intestinal endotoxemia and hepatic injury.

AIM:To investigate the effect of lipopolysaccharides(LPS)preconditioning on CCl4-induced liver injury and the change of LPS signal transduction.METHODS:The male Wistar rats were divided randomly into liver-injury group,which were injected with CCl4 5 mL/kg first,three days later were injected 0.3 mL 40% CCl4 and 60% olive oil. Animals in LPS preconditioning group were injected with LPS 0.5 mg/kg before the day CCl4 was given. Rats received high fat diet were as liver injury group,and normal control group received normal diet. The lymphocytes infiltrated in the liver tissue were counted. The endotoxin and ALT level in rat plasma,TNF-? content and expressions of TLR4,p38,p-p38,I??,NF-?? in the rat livers were also determined.RESULTS:The lymphocytes in liver slice and ALT level of the plasma in LPS preconditioning group were lower significantly than those in the liver injury group,and the expressions of TLR4,p-p38,NF-?? in the liver were the same. In contrast,the expression of I?? was higher.CONCLUSION:LPS preconditioning relieves obviously CCl4-induced chronic liver injury. The mechanism may be associated with change of signal transduction of LPS,which results in decrease of pre-inflammatory cytokines.

Objectives To explore the relativity between Alzheimer ’ s disease ( AD)-like lesions and metabolic syndrome models induced by high-sugar high-fat diet in rats.Methods Forty-eight Sprague Dawley rats were randomly divided into 2 groups.The control group (fed with normal diet, 12 rats) and high sugar and high fat group (fed with high-sucrose and high-fat diet, 12 rats) continuously for 12 months.At the end of 6, 9 and 12 months of the experiment , we observed the animal body weight and visceral fat weight .The blood lipid levels , blood glucose and MS-related biochemical parameters were determined . The brain tissues were examined by histopathology . The characteristic AD molecules hippocampus Aβand Tau were detected using ELISA and Western blotting to confirm the presence of AD lesions in the brain.Results Compared with the normal control group , the body weight and visceral fat weight of the rats in the high-sugar high-fat groups were significantly increased; the levels of TG , FPG, LDL, HOMA-IR and hippocampus Aβ,phosphorylated Tau (p-Tau) were higher, but the level of HDL was decreased (P<0.05 for all).The histopathological examination revealed inflammatory cell infiltration in the brain tissues .Conclusions Characteristic AD-like lesions may occur and accompany the rat models of metabolic syndrome , induced by high-sugar high-fat diet, and provide a new idea for the construction of Alzheimer ’ s disease animal models .
