Objective: In addition to pH regulation, Na\++/H\++ exchanger (NHE) has been shown to facilitate cell growth and proliferation. However, the effects of long-term inhibition of Na\++/H\++ exchange on cardiac structural and functional remodeling post myocardial infarction (MI) are still controversial. The present study was therefore carried out to further investigate the effects of long-term treatment with cariporide, a specific inhibitor of NHE-1, on cardiac remodeling after MI in rats; Methods: Male Wistar rats that underwent coronary ligation were randomly selected for cariporide treatment starting 6 h after induction of MI or no *** was continued up to 6 weeks post MI, after which, the arterial, venous and left ventricular catheters were chronically implanted. Twenty-four h later, after hemodynamic signals were recorded in conscious rats, they were sacrificed and hearts were taken out for morphological examinations; Results: Cariporide treatment decreased the heart weight and heart weight to body weight ratio (both \%P\%left ventricular end-diastolic pressure (\%P\%l contractility (d\%P\%/d\%t\%\-\{max\}) (\%P\%l of treated rats compared to that of untreated infarct rats; Conclusion: The results of the present study indicate that the long-term inhibition of NHE with cariporide can attenuate cardiac structural remodeling and improve left ventricular dysfunction in infarcted rats, and suggest that Na\++/H\++ exchange inhibition could be an effective therapeutic strategy for myocardial infarction-induced heart failure.

EFFECT OF MAGNETIC FIElD ON CAlCITONIN GENE-RElATED PEPTIDE IN PERIODONTAl lIG AMENTS OF RATS

The 2nd International Symposium on Computer-Aided Welding Engineering

作者： S.J. Wang G.l. qin Y.H. Su Key laboratory for liquid-Solid Structure Evolution and Processing of Materials Ministry of Education Shandong University

Aluminum alloy plate were jointed to galvanized steel sheets with lap joint by laser-MIG hybrid brazing-fusion welding with AlSi5, AlSi12, AlMg5 filler wires, and the influences of Si and Mg on the microstructure characteristics and mechanical properties of the brazed-fusion welded joint were studied. The increase of Si element in the fusion weld, it can make the grain refinement, and increase the microhardness of the fusion weld. Therefore, the microhardness value in the seam made with AlSi12 filler wire is 98.4 HV 10 , which is higher than 96.8 HV 10 that made with AlSi5 filler wire and 70.4 HV 10 that made with AlMg5 filler wire. The highest tensile strength can reach 178.9 MPa made with AlMg5 filler wire. The tensile strength is 172.43 MPa made with AlSi5 filler wire. However, the lowest tensile strength is 144 MPa made with AlSi12 filler wire. The average thickness of the intermetallic compound （IMC） layer with AlSi5, AlSi12, AlMg5 filler wires is 1.49-2.64ìm, which is less than the limited value of 10ìm. The IMC layer made with AlSi5, AlSi12 filler wires are identified as FeAl2 , Fe2Al5 , Fe4Al13 and Al 0.5 Fe3Si0.5 . However, the IMC layer made with AlMg5 filler wire are identified as FeAl2, Fe2Al5 and Fe4Al13 .
