Aim To explore the effects of lipoteichoic acid (LTA) induced delayed preconditioning (PC) on hypoxia-reoxygenation (H/R) injury of cultured human coronary artery endothelial cells (HCAECs), and to investigate the potential role of endogenous nitric oxide (NO) participated in the protective mechanism. Methods HCAECs were incubated for 2 h in a hypoxic atmosphere and reoxygenated for 4 h in a normoxic atmosphere. The delayed PC was induced by pretreatment with LTA assessed by the percentage of cellular injury with Trypan blue exclusion and by the amount of lactate dehydrogenase (LDH) in culture media. The NO level of the culture media was measured detect the expression of eNOS mRNA by RT-PCR method after cells were recovered from different points.Results LTA pretreatment significantly decreased the percentage of the killed cell and the concentration of LDH in media. Also, LTA pretreatment obviously raised the concentrations of NO in culture media. The protective effects of LTA were abrogated by pretreatment with N-monomethyl-L-arginine (L-NMMA).Moreover, the expression of eNOS mRNA was significantly upregulated after HCAECs exposure to LTA for 4 h following 2 h or 4 h recovery. Conclusion LTA could induce the delayed protection against H/R induced endothelial injury and dysfunction of cultured HCAECs. NO produced by eNOS acts initially as a trigger and subsequently as a mediator of delayed PC.

To investigate the relationship between the effects of arecoline hydrobromide on contraction of the smooth muscles in oncomelania foot, and explore the mechanism of arecoline hydrobromide in decreasing climbing adhesion and increasing snail－killing. 　Method: The in vitro experiment was used to observe the effects of arecoline hydrobromide on contraction activitive of foot smooth muscles of oncomelania. 　Results: With a concentration of 3×10-6mol*L-1, arecoline hydrobromide strengthened the contraction and increased the frequency of the contraction of the foot smooth muscles of oncomelania, which was antagonized by verapamil. The same concentration of arecoline hydrobromide enhanced the contraction of smooth muscles in Ringer's solution with ECTA but Ca2+, and this effect was antagonized by caffeine. The concentrations of 10－5 and 3×10－5mol*L-1 of arecolin hydrobromide blocked the effect of Bay K8644 in enhancing foot smooth muscle contraction, with a characteristic of concentration－dependence. 　Conclusion:Arecoline hydrobromide may block the calcium channel of the smooth muscles in oncomelania foot. This could provide an explanation why arecoline hydrobromide decreases the rate of oncomelania climbing adhesion and enhances snail－killing.

AIM: To study the potential effects of lipoteichoic acid (LTA)-induced delayed preconditioning (PC) on cardioplegic arrest/reperfusion injury in donor rat heart. METHODS: The rats were pretreated with LTA (1 mg/kg, ip) 24 h before the experiment, and the isolated hearts were subjected to arrested by cardioplegic solution and stored in Eurocollin's solution for 4 h by the Langendorff method, and to evaluate the changes of cardiac function at the reperfusion for 30 min and 60 min, to measure the amounts of MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH) and total nitric oxide (NO) oxidation products in the coronary effluent, and to detect myocardial apoptosis on tissue samples of left ventricle at the end of reperfusion by TUNEL staining. RESULTS: Pretreated with LTA significantly improved the recovery of cardiac function with a significant increase in coronary flow (CF), left ventricular developed pressure (LVDP), maximal rate of left ventricular developed pressure (+dp/dt_ max), and minimal rate of left ventricular decline pressure (-dp/dt_ max) at 30 min and 60 min of reperfusion (all P

To explore the potential of lipoteichoic acid (LTA) induced cardioprotection against ischemia-reperfusion (I/R) injury in isolated rat hearts and whether endogenous nitric oxide (NO) participates in the protection, the rats were pretreated with LTA (1 mg/kg, i.p.) 24 h before the experiment, and the isolated hearts were subjected to 30 min no-flow normothermic global ischemia and 60 min reperfusion after a 20-min stabilization period by the langendorff method. Cardiac functions were evaluated at the end of stabilization, and at 30 min, 60 min of reperfusion. The amounts of MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase(LDH) and total NO oxidation products in the coronary effluent were measured spectrophotometrically at the end of reperfusion. It was revealed that pretreatment with LTA could significantly improve the recovery of cardiac function, reduce the release of CK-MB and LDH, and increase the concentrations of NO in coronary effluent. The protective effects were abrogated by pretreatment of the rats with L-NAME. It was concluded that LTA could induce the delayed cardioprotection against I/R injury, and endogenous NO may be involved in the mechanisms.
