Abstract

Research background. Circulating Endothelial Cells (CEC) is a reflection of endothelial damage or endothelial stress, increasing of CEC amount depend on endothelial mechanism, edothelial adhesivity damage and cellular apoptosis as a result of decreasing sitoskleleton function. If higher exposure affects the increasing of CEC amount,VEGF other growth factor mediators will be reflected as endothelial stress manifestation which roles in the increasing of re-population and Endothelial Progenitor Cells (EPC) differentiation. Endothelial Progenitor Cells is a mononuclear cell (a part of stem cell) that could change to be mature endothel and roles in re-edothelialisation and neovascularisation. This research aimed to investigate the ratio of EPC : CEC in risk group through Framingham Risk Score (FRS) 10 years approach as endothelial dysfunction predictor.Research method and result. There were 55 research subjects whom taken by FRS scoring and devided into some risk groups and two control groups. They were control group I (health) and control group II (sick). Base blood was taken to every each of them to analyze their EPC and CEC with Flowcytometry. EPC was analyzed by CD34 Per CP Santa Cruz SC-19621 and CD 133 FITC (fluorescein isothiocyanate) Bioss bs-0395R-FITCmarker.WhileCEC was analyzed CD45 FITC Biolegend 202205 dan CD 146 PE Biolegend 134704 marker. Result showed, there was significant ratio differences of EPC : CEC in those six groups which was proven by p-value 0.032< ? (0.05). The higher ratio was in high risk group (139.06).Conclusion. Research showed that EPC amount was increase related to the increasing of high risk level according to FRS 10 years, but its increasing did not followed by its ability to homing in injury area as role part in re-endothelialisation process. It found that EPC amount was higher in high risk group than in low risk group.

Abstract

Research Background. Stroke as brain vascular disorder that can be ruptured vascular commonly referred to as a bleeding stroke or ischemic stroke may be due to cerebral arterial thrombosis as a final impact the progression of atherosclerosis, especially in the area of branching blood vessels. Atherogenesis related to endothelial dysfunction as a consequence shear stress exposure leads endothelial cells undergo premature senescence and activation of endothelial than occur endothelial detachment from the basement membrane as a circulating endothelial cells (CEC). Mechanism shears stress on endothelial activation can not be separated from the increased production of hydrogen peroxidase (H2O2), which will activate the PPAR-? then increase levels of free fatty acids are capable of modulating the uncoupling protein 2 (UCP 2) gene as a compensation for lowering of free fatty acids.Reseach Methods and Results. Researchers used 40 subjects were classified into two categories on a range of healthy and sick, who then performed blood sampling edge for lipid profile analysis, CEC using flowcytometry, H2O2 measurement with ELISA techniques and DNA isolation followed by PCR procedures with the Genomic DNA that has been extracted from blood samples amplified with the 5’-GCT GCT CAC AGG TCT GCC AC-3’sebagai forward primer and 5’-AGG CGT CAG GAG ATG GAC CG-3’sebagai reverse primer (Sesti et al, 2003; Oktavianthi et al, 2012). Genotype (-866) AA is characterized by fragments of 363 bp cutting results Mlu1 sites, whereas genotypes (-866) GG marked on fragments of 295 bp and 68 bp. The equipment used was a thermal cycler (Gene Amp® PCR System 9700 [Applied Biosystems, Foster City, CA, USA]). Results showed thatConclusion. CEC in the group sick 3 times higher than the healthy group as well as the levels of H2O2, but the two groups are not found polymorfism in both groups. Similarly, from the analysis of UCP2 gene allele frequencies between groups of stroke was not significantly different from the control group, this means yet certain UCP2 gene predispose and contribute to the pathogenesis of stroke.
