Objective To investigate the protective effect of osthole on focal cerebral ischemia-reperfusion injury in rats.Methods Focal cerebral ischemia-reperfusion model in rat was made by transient occlusion of the middle cerebral artery for 2 h and followed by reperfusion for 24 h.Osthole 5 and 10 mg/kg were iv injected through sublingual vein at 1 h after the onset of ischemia,respectively.After 24 h of reperfusion,the influence of osthole on neurological behaviour deficit score,brain edema,and infarct size were evaluated.The activity of Na+,K+-ATPase,Ca2+-ATPase,and myeloperoxidase(MPO)in the ischemic hemisphere cortex of the middle cerebral artery area was assayed by spectrophotometry.The level of IL-8 was detected with radioimmunoassay.Results Osthole significantly reduced the neurological behaviour deficit score,brain edema,and infarct size,enhanced the activity of Na+,K+-ATPase and Ca2+-ATPase,inhibited the activity of MPO,and decreased the level of IL-8 in the brain tissue.ConclusionThe results suggest that osthole could attenuate the brain damage following focal cerebral ischemia-reperfusion in rats and its mechanism may be partly related to the inhibition of inflammation and brain edema induced by ischemia-reperfusion.

To explore the kinetics of LBP/CD14 system in patients with hemodialysis, and further to analyse its role in (he development of systemic inflammation response based on the changes of plasma endotaxin, TNF and IL-6 levels in patients with uremia treated with hemodilysis. Methods Sixteen patients with end-stage renal failure (8 cases with hemodialysis, 8 cses without hemodialysis) were selected for this study. limulus amebocyte lysate chromogenic assay, ELISA and cell in situ hybridization were used to determine the changes in endotoxin, LBP, TNF and IL-6 levels in plasma, and expression of CD14 mRNA in the monocytes. Results (l)Plasma LBP levels in patients with hemodialysis were significantly higher than those in patients without hemodialysis. The expression of CD14 mRNA in the monocytes in patients with hemodialysis was also more obvious. Both of them incresed much more in hemodialysis. (2)Plasma endotoxin levels in patients with hemodialysis, though being significantly higher than in patients without hemodialysis, were in low-level (61.7 ? 10.6 pg/ml). (3) Plasma TNF and IL-6 levels were markedly increased in patients with hemodialysis, which were significantly correlated with plasma LBP levels. Conclusion LBP/CD14 system in patients with hemodialysis is markedly up-regulated, which might be the important mechanism for low-level endotoxemia to exert its effects in hemodialysis.

AIM:To investigate the protective effects of total saponins of panax notoginseng (PNS) on myocardial hypertrophy and fibrosis induced by isoproterenol (ISO) in rats. METHODS: Myocardial hypertrophy and fibrosis model of rats were induced by injection of ISO (5 mg?kg-1?d-1, sc) for 7 days. From day 2, the rats were administered with PNS at dose of 25 and 50 mg?kg-1?d-1, ip for 14 days, the control and ISO model group were received saline injection. Then, the heart-weight (HW), left ventricular weight (LVW), the ratio of HW/BW and LVW/BW (LVI) were measured; the hydroxyproline and malondialdehyde (MDA) and angiotensin (AngII) content of left ventricle. The level of nitric oxide (NO), nitric oxide synthase (NOS), superoxide disrnutase (SOD) and glutathione peroxidase (GSH-Px) activities in left ventricle were determined by spectrophotemetry and radioimmunoassay, respectively. RESULTS: Compared with NS control group, the ratio of HW/BW, LVW/BW and the content of hydroxyproline, AngII, MDA and iNOS activity in the left ventricle were significantly increased. The cNOS, SOD, GSH-Px activities and NO content were obriously decreased in the ISO model group. After treatment with PNS, the left ventricular NO content, cNOS, SOD and GSH-Px activities were markedly higher than those in ISO model group. The content of MDA, AngII and iNOS activities and the ratio of HW/BW, LVI were significantly lower than those in ISO model group. CONCLUSION: PNS reverses the myocardial hypertrophy and fibrosis induced by isoproterenol in rats. This effect may be related to eliminating the oxygen free radicals and raising NO level.
