Objective To explore the effects of Ginkgolide B on the expression of hypoxia inducible factor 1 α (HIF-1α) and P I3K/Akt pathway in the hippocampus of developing rats after pentylenetetrazol(PTZ)-induced status epilepticus,and to investigate the correlation between HIF-1α expression and PI3K/Akt pathway.Methods Ninety-six SD rats aged 21 days were randomly divided into normal saline group(group NS),status epilepticus group (group P),GKB treatment groups (group G+P),GKB +wortmannin treated group (group G+P+W),wortmannin treated group(group P+W).The brain tissue were harvested from the rats at 4 and 8 hours after the inducement,but in the group G+P at 1 h,4 h,8 h,24 h.Immunohistochemistry and Western blot were used respectively to detect HIF-1α and p-Akt protein expression.Results (1) For the group G+P,there were statistical differences in the expression levels of p-Akt protein between 1 h,4 h,8 h and 24 h(P＜0.01),The p-Akt protein reached the peak level at 4 hours (0.85±0.03),there were statistical differences in the expression levels of HIF-1α protein between 1 h,4 h,8 h and 24 h(P＜0.01),the HIF-1α expression reached the peak level at 8 hours(1.00±0.13).(2) The expression of HIF-1α in all the groups at 8 hours time point:the expression levels of HIF-1α in the group P and group G+P were significantly higher than those in the group NS (P＜0.01) and the expression levels of HIF1α in the group G+P were higher than those in the group P(P＜0.01).Using wortmannin,the PI3K/Akt specific inhibitor,HIF-1α protein expression in the group G+P+W and P+W was significantly decreased when compared with the group G+P and P (P＜0.01).(3)The expression of p-Akt in all the groups at 4 hours time point:the expression levels of p-Akt in the group P and group G+P were significantly higher than those in the group NS (P＜0.01) and the expression levels of p-Akt in the group G+P were higher than those in the group P (P＜ 0.01).Using wortmannin,p-Akt protein expression in the group G+P+W and P+W was significantly decreased when compared with the group G+P and P (P＜0.01).Conclusion GKB can activate PI3K/Akt signaling pathway,and the pathway is involved in regulating the expression of HIF-1α.

AIM: To observe the degree of gastric mucosal injury following limb ischemia/reperfusion(LIR),and to investigate the mechanism of gastric mucosal injury and the influence of the series of brief ischemia/reperfusion of hind limbs of rats on gastric mucosal injury. METHODS: Referring to Rosenthal's method, the model rats which underwent 4 hours of ischemia and 4 hours of reperfusion in hind limbs were made. The indexes of gastric mucosal injury after LIR and ischemic preconditioning (IPC) + LIR were determined. The morphologic changes were observed with light microscope and transmission electron microscop respectively. The GMBF,histologic lesion score, gastric barrier mucus, phospholipids, hexosamine, nitric oxide and nitric oxide synthase in mucus were measured in different groups. RESULTS: Serious damage in gastric mucosa was observed under microscope and EM after LIR. But less serious damage was observed in the IPC group. After LIR, compared to the control group, the GMBF and the content of gastric barrier mucus, phospholipids and hexosamine in mucus decreased significantly. There was significant difference in most indexes between the control group and the IPC group, but compared to LIR group, the histologic lesion score decreased significantly and the GMBF and the content of gastric barrier mucus, phospholipids, hexosamine ,nitric oxide and nitric oxide synthase in mucus increased significantly. CONCLUSION: LIR caused the gastric mucosa injury. IPC alleviated the damage of gastric mucosa following ischemia/reperfusion in hind limbs.

BACKGROUND: Limb ischemia reperfusion (LIR) as a stressor leads to gastric mucosal injury, and then results in the occurrence of stress ulcer.OBJECTIVE: To observe the effects of LIR on gastric mucosal injury, investigate part of the mechanism, and the role of several transient limb ischemia in the occurrence of gastric mucosal injury.DESIGN: A randomized grouping design and controlled animal experiment.SETTING: Department of Pathophysiology of North China Coal Medical College.MATERIALS: The experiment was carried out in the pathophysiological laboratory of North China Coal Medical College from January to June 2002. Fifty-four healthy adult male Wistar rats were randomly divided into three groups with 18 rats in each group. Ischemia reperfusion (I/R) group: The rats were duplicated into models according to the Rosenthal method that under superficial anesthesia with ether, the roots of both hindlimbs were ligated by wrapping with rubber strap, blood flow was blocked for 4 hours and then recovered to perfusion for 4 hours, and finally killed by bleeding from abdominal aorta. Ischemic preconditioning group: Before model establishment, blood flow of both hindlimbs was blocked for 5 minutes, and then recovered to perfusion for 5 minutes, which was repeated for four times, and the following operations were the same as those in the I/R group. Control group: The operations were the same as those in the I/R group,but both hindlimbs were ligated at relaxation without blocking the blood flow.METHODS: Sections of gastric mucosa were prepared, and then observed under light microscope and electron microscope, and the index of gastric mucosal injury was determined according to the Guth standard. The colorimetric assay was performed with 721 spectrophotometer at 650 nm, and the amount of gastric combining mucus was calculated.Meanwhile, the blood flow of gastric mucosa, contents of phospholipid and hexosamine in gastric mucus, content of nitric oxide in plasma and gastric tissue and activity of nitric oxide synthase (NOS) in gastric mucosa were determined.MAIN OUTCOME MEASURES: Index of gastric mucosal injury, amount of gastric combining mucus, blood flow of gastric mucosa, contents of phospholipid and hexosamine in gastric mucus, contents of nitric oxide in plasma and gastric tissue and NOS activity in gastric mucosa.RESULTS: All the 54 rats were involved in the analysis of results. ① In the I/R group, gastric mucosal injury was serious, edema, hyperemia, erosion and disintegration of gland of mucosal glands were observed, infiltration of inflammatory cells (formation of ulcer) was observed in basal and inferior mucosa. In the ischemic preconditioning group, the gastric mucosa was complete, and the damaged severity was milder than that in the I/R group; Under electron microscope, the organell structures of gastric parietal and chief cells were incomplete and destroyed. The cell injuries in the ischemic preconditioning group were milder than those in the I/R group (index of injury: 18.00±10.71, 34.00±15.01, P＜ 0.01). ② The blood flow and combining mucosal amount of gastric mucosa, contents of phospholipid and hexosamine in gastric mucus in the ischemic preconditioning group and I/R group were all obviously lower than those in the control group [(2.12±0.56), (10.84±2.56), (25.52±2.97) mL/(kg·h); (2.01±0.91), (2.79±0.73), (3.99±0.87) mg;(7.68±1.95), (9.74±1.04), (11.98±1.98) mg/g; (3.83±1.18), (5.42±0.47), (5.76±1.21) mg/g, P ＜ 0.05, 0.01], those the above indexes were all higher in the ischemic preconditioning group than in the I/R group. ③ The contents of nitric oxide in plasma and gastric tissue and NOS activity in gastric mucosa in the ischemic preconditioning group and I/R group were significantly lower than those in the control group [(250.0±5.6), (270.0±11.3), (210.0±7.4) μmol/L; (9.34±0.67), (11.34±1.00), (7.50±0.67) μ kat/g, P ＜ 0.01], those were also signficantly higher in the ischemic preconditioning group than in the I/R group.CONCLUSION: As a stressor, LIR can lead to gastric mucosal injury, and cause stress ulcer.Ischemic preconditioning can alleviate the gastric mucosal injury following LIR
