Abstract :
Objective of the study: Analyzing the transformation that occurs in the experimental animal’s endothelium infected by Helicobacter pylori. Cytokine which has a role in endothelial dysfunction will be analyzed and comparison between the experimental animal that has been infected by Helicobacter pylori and the experimental animal that is not infected by Helicobacter pylori was pursued. Method of the study: The research is categorized as Experimental research using Rattus norvegicus as an object of research. It consists of two group. First group is a control group and the second one is intramuscularly induced by LPS Helicobacter pylori three times with 3-day interval. Afterward, the indicator of endothelial dysfunction, TNF-alpha, e-selectin, MMP-8 and VCAM will be analyzed by using method of immunohistochemistry. The result of research: After conducting the Mann-Whitney T-Test and Spearman’s Rho Correlation Test, it is concluded that there is significant difference between the control group and the group with treatment (TNF-alpha, p=0,001, VCAM, p=0,008, MMP-8, p=0,00, e-selectin, p=0,008). It can be seen that there is a good correlation between TNF-alpha and e-selectin. Conclusion: LPS Helicobacter pylori encouraged lesion in arterial endothelium and finally causes atherosclerosis.
