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.

Pengaruh Likopen terhadap Penurunan Aktivitas Mitogen-Activated Protein Kinase (MAPK) dan Ekspresi Endothelin-1 (ET-1) pada Kultur Huvecs yang Dipapar Leptin Fatmawati, Heni; Satuman, Satuman; Rudijanto, Ahmad; Indra, Muhammad Rasjad

The effect of obesity on vascular function is mediated by hormon leptin. Leptin has been proved to increaseoxidative stress in endothelial cell. The previous study has proven that leptin caused the endothelial dysfunction asa step of the atherogenesis. Lycopene, an antioxidant, is presumed having the ability to block the atherogenesismechanism, which is stimulated a proinflamatory cytokine and adhesion molecules by MAPK and transcriptionfactor ET-1. Therefore, the aim of this research was to prove and to determine whether lycopene could decreasethe MAPK and ET-1 expression in Human Umbillical Vein Endothelial Cells (HUVECs) culture induced by 500 ng/mlleptin. In vitro study used primary culture of the HUVECs were devided in to 7 groups, there were (1) 0 ng/ml leptinand 0 ìM lycopene, (2) induced by 500 ng/ml leptin for 12 hours, (3) induced by leptin and lycopene with concentration10; 25; 40; 55 and 75 ìM for 12 hours. Then the identification of MAPK was applied by using imunocytochemistrycompared with ELISA procedure on cell endothel culture lysate and ET-1 expression was measured by using RTPCR. It was showed that lycopene 10-25 ìM decreased MAPK and ET-1 expression significantly in HUVECs cultureinduced by leptin 500 ng/ml. Leptin was increased ERK1/2 MAPK and ET-1 expression in HUVECs culture and candecrease by lycopene. Optimum dose of lycopene is 10-25 ìM.

STUDY OF SOME BIOCHEMICAL PARAMETERS IN YOUNG MEN AS EFFECTED BY RAMADAN FASTING Indra, M. Rasjad; Satuman, Satuman; Widodo, Edwin; E.H, Tinny; S.W, Endang; Sudiarto, Sudiarto; Soemardini, Soemardini

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 (p 0.05) 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.

Introduction: The use of essential oils in aromatherapy is widespread. However, few studies have explored the effects of smoke from the evaporation of commonly used essential oils. While essential oils are promoted for various benefits, prolonged exposure to inhaled particles from essential oil smoke may pose potential health risks. This study aimed to examine the effects of essential oil vapors on mice. Methods: This was an experimental study investigating the effects of different treatments on lung immunohistopathology, endothelial nitric oxide synthase (eNOS) expression, serum nitric oxide (NO) levels, and serum surfactant protein-D (SP-D) as an inflammation marker in mice. A total of 40 adult male Mus musculus mice (25–30 g) were randomly divided into four groups. Inflammation models were established by exposing the mice to a gas mixture containing vegetable glycerin, propylene glycol, and vitamin E acetate solution. Following inflammation induction, the mice received seven-day interventions with 0.9% NaCl solution, Eucalyptus globulus essential oil (EgEO), and citronella essential oil (CtEO), alongside an untreated inflammatory group. Results: The CtEO group intervention showed significant increases in eNOS expression (P=0.001) but no significant increase in NO compared to the other groups. The correlation analysis of eNOS expression in lung cells, serum NO, and SP-D levels was not significant, P>0.05 (p=0.160; p=0.115; p=0.234). Conclusion: Gas intervention containing 100% oxygen (O2) and CtEO steam increased eNOS expression on the immunohistochemistry (IHC) examination of mice.
