    Introduction. Obesity is a metabolic syndrome as risk factor to the cardiovascular disease. Obesity occurs caused by adipocyte massive that is started by proliferation and differentiation of preadipocytes that involves transcription factors such as C/EBPα ,PPARγ and SREBP-1. Is known the TNF α and [Ca2+]i Increase when adiponectin decrease at the end of adipocyte differentiation. Therefore it is a deemed treat the obesity through the inhibition of adipocyte proliferation and differentiation using natural resources. Quercetin in due of the flavonoid found in apple,vegetables etc. The aim of this study is to prove the affectivity of quercetin to inhibit proliferation and differentiation of preadipocyte through inhibited of C/EBPα in rat preadipocytes culture method. Methods. Their study was a laboratory experimental. Quercetin was exposed to the preadipocytes human culture, after it was induced by differentiation stimulator the doses quercetin was grouped in: control, 50 µM (Q50), 125 µM (Q125) and 625 µM (Q625) groups. The amount of proliferation and differentiation was descriptive analyzed. The expression of C/EBPα, were identified by Immunocytochemistry and western blotting. Result. Quercetin 100 inhibited the rate of proliferation cell, while quersetin 625 inhibited differentiation in preadipocytes culture. There was a dose dependent to quersetin towards the decrease of PPARγ expression and C/EBPα expression in this preadipocytes culture. Conclusion. It is conclusion that quersetin inhibits proliferation and differentiation preadipocytes culture through the decrease of the expresion of C/EBP α

    BackgroundThe aim of this study is to develop a method for optimal in vitro proliferation and differentiation of rat adipocyte. MethodsPreadipocyte were isolated from omentum of Rattus norvegicus Wistar using Collagenase type I dan II (Sigma). Cells were cultured in M199 culture containing either 0%, 8% or 10% Fetal Bovine Serum (FBS). Insulin were added into the media once the cells attached to the culture plate Proliferating and differentiated cells were counted and analysed by using Oil Red O dan Hematoxylen (HE) staining. Results This study demonstrated that adipocyte could be isolated using Collagenase type I but not type II. The addition of 10% FBSsignificantly increased the number of preadipocyte and differentiation of adipocyte more than those of 8% FBS and without FBS. The timing of FBS addition was best performed on day 8 using 10% FBS. Specific adipocyte staining using Oil Red O revealed thatthere were core lipids in mature adipocyte. ConclusionsCollagenase tipe I could be used to isolate preadipocyte cells. Supplementation of culture media with 8-10% FBS could enhance the in vitro proliferation of preadipocyte. Standard media M199 containing 10% FBS and insulin may provide an environment to differentiate preadipocyte specifically into adipocyte in vitro

    Aim: to detect the levels of CEC and expression of NFκB in the three groups of subjects with certain conditions. Methods: this study is an exploratory study using human peripheral blood samples. The study subjects comprised three groups, the group of 23 healthy people, a group of 35 people that has one or more risk factors for vascular disease and a group of 15 vascular disease patients (coronary heart disease, diabetes mellitus, stroke). CEC were isolated from peripheral blood mononuclear cells (PBMC). CEC level is identified through the measurement of CD45 and CD146 by flowcytometry method. NFκB expression is recognized by ELISA method (imgenex, USA). Results: the highest average levels of CEC were found in the sick group (28.6%). The highest average expression of NFκB (924.9495) is found in the group with risk factors. The lowest average expression of NFκB and CEC is found in the healthy group. Statistical analysis of ANOVA at the interval confidence of 95% shows a significant difference (p=0.00) levels of CEC and NFκB expression between the healthy group with the group with the risk of cardiovascular disease (CVD) and patients with known CVD. Conclusion: increase of level CEC and NFκB expression has a strong relationship with vascular disease and its risk factors. Key words: circulating endothelial cells (CEC), nuclear factor kappa beta (NFκB), peripheral blood mononuclear cell (PBMC), vascular disease

    The effect of Ramadan fasting on some blood parameters i.e. serum glucose, urea, uric acid, lipids and proteins, were investigated on young men in Ar Rohmah Islamic dormitory. Nineteen normal and healthy students aging between 12-25 years, residing in the Islamic dormitory, voluntarily to participated in the study. Blood samples were obtained from the volunteers on the 1st and 26th day of Ramadan and analyzed for the aforementioned biochemical parameters. A non-significant effect of Ramadan fasting was observed on most of the parameters studied. However, serum urea, triglycerides, total cholesterol and LDL-cholesterol were reduced significantly (p0.05) but remained within the physiological limits. Decrease in blood urea has been attributed to the effect of at least protein and triglycerides intake to increase lipolytic effect. The reduction in serum cholesterol and LDL is a beneficial effect of Ramadan fasting. The results of the study indicated thatRamadan fasting is quite safe for normal healthy adults

    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

    There is adipocytokine dysregulation on obesity such as amplified leptin, and reduced adiponectin at serum levels . Leptin has been proved to increase oxidative stress in endothelial cell. The adipocyte functions as an important secretory organ via nuclear factor-κ B (NF-κB) releasing a number of bioactive molecules such as leptin. Lycopene, an antioxidant, is presumed having the ability to block the atherogenesis mechanism, which is stimulated a proinflamatory cytokine and adhesion molecules ICAM-1 by NF-κB. Therefore, the aim of this research was to prove and to determine whether lycopene could decrease the NF-κBandICAM-1 expressionin Human Umbillical Vein Endothelial Cells (HUVECs) culture induced by 500 ng/mL leptin. In vitro study used primary culture of the HUVECs were devided in to 7 groups, there were (1) 0 ng/mL leptin and 0 μM lycopene, (2) induced by 500 ng/mL leptin for 12 hours, (3) induced by leptin and lycopene with concentration 10; 25; 40; 55 and 75 μM for 12 hours. Then the identification of NF-κB was applied by using imunocytochemistry compared with ELISA procedure on cell endothel culture lysate and ICAM-1 expression was measured by using RT PCR. It was showed that lycopene 25 μM decreased NF-κB level and ICAM-1 expression significantly in Human Umbillical Vein Endothelial Cells (HUVECs) culture induced by leptin 500 ng/mL.Leptin was increased NF-κB and ICAM-1 expression in HUVECs culture and was decreased by lycopene. Optimum dose of lycopene is 25 μM
