Abstract: Margarine is a kitchen ingredient that contains trans fat which plays an important role in the formation of atherosclerosis. Alcohol is one of the compounds that can slow down the formation of foam cells which are the beginning of atherosclerotic lesions. This study was aimed to determine the effect of alcohol administration on the aortic histopathological features of Wistar rats induced by margarine. This was an experimental laboratory study. Samples were 20 Wistar rats divided into 4 groups, as follows: negative control (KN), given pellet only; positive control (KP), given pellet and margarine 5 g per day; treatment 1 (P1), given pellet, margarine 5 g, and wine (14% of alcohol) 0.18 ml per day; and treatment 2 (P2), given pellet, margarine 5 g, and wine 0.36 ml per day. All samples were terminated at day 29. Rat aortas were prepared for microscopic slides. The results showed that foam cells were found in the aortic layers. The highest number of foam cells was found in KP group, followed by P1 group, meanwhile P2 group had the lowest number of foam cells. Conclusion: In the aortas of Wistar rats given wine in moderate dose concomitantly with margarine (P1 and P2 groups), the numbers of foam cells were less than in Wistar rats that were given margarine only (KP group).Keywords: wine, histopathology of aorta, atherosclerosis, margarine Abstrak: Margarin merupakan bahan dapur yang mengandung lemak trans yang sangat berperan dalam pembentukan aterosklerosis.

Abstract: Honey has various health benefits due to the antioxidant activities of two compounds namely phenolic and flavonoid. These two compounds are speculated to confer prevention and therapeutic effects on atherosclerosis. Atherosclerosis is caused by a number of factors, one of which is hyperlipidemia. This study was aimed to investigate the effects of honey administration on the histopathological features of the aorta of Wistar rats (Rattus norvegicus) induced by margarine. This was an experimental study employed 19 rats divided into four groups. Negative control (NC) group, received no treatment; positive control (PC) group, given margarine 5g/day/rat for 28 days; P1 group, given margarine 5g/day/rat and honey 2 ml/day/rat simultanously for 28 days; and P2 group, given margarine 5g/day/rat for 28 days followed by the administration of honey 2 ml/day/rat for the next 7 days. Three groups NC, PC, and P1 were terminated at day 29, while P2 group was terminated at day 36. The results showed that the histopathological features of the aorta of wistar rats were normal in P1 group as well as NC group. On the other hand, PC and P2 groups exhibited the presence of foam cells, although the number of foam cells was fewer in P2 group compared to PC group. Conclusion: Honey exhibits preventive effects on atherosclerosis in the aorta of Wistar rats induced by margarine which was indicated by the reduction of the number of foam cells on the histopathological features of the aorta.Keywords: honey, margarine, atherosclerosis Abstrak: Madu memiliki banyak manfaat karena aktivitas antioksidan yang terkandung di dalamnya, yaitu fenolat dan flavonoid.

Abstract Objectives Lead primarily affects male reproductive functions via hormonal imbalance and morphological damage to the testicular tissue with significant alteration in sperm profile and oxidative markers. Though, different studies have reported that Cocos nucifera L. oil has a wide range of biological effects, this study aimed at investigating the effect of Cocos nucifera L. oil on lead acetate-induced reproductive toxicity in male Wistar rats. Methods Twenty (20) sexually matured male Wistar rats (55–65 days) were randomly distributed into four groups (n=5). Group I (negative control)—distilled water orally for 56 days, Group II (positive control)—5 mg/kg bwt lead acetate intraperitoneally (i.p.) for 14 days, Group III—6.7 mL/kg bwt Cocos nucifera L. oil orally for 56 days and Group IV—lead acetate intraperitoneally (i.p.) for 14 days and Cocos nucifera L. oil for orally for 56 days. Rats were sacrificed by diethyl ether, after which the serum, testis and epididymis were collected and used for semen analysis, biochemical and histological analysis. Results The lead acetate significantly increases (p<0.05) testicular and epididymal malondialdehyde (MDA) levels, while a significant reduction (p<0.05) in sperm parameters, organ weight, testosterone and luteinizing hormone was observed when compared with the negative control. The coadministration of Cocos nucifera oil with lead acetate significantly increases (p<0.05) testosterone, luteinizing hormone, sperm parameters and organ weight, with a significant decrease (p<0.05) in MDA levels compared with positive control. Histological analysis showed that lead acetate distorts testicular cytoarchitecture and germ cell integrity while this was normalized in the cotreated group. Conclusions Cocos nucifera oil attenuates the deleterious effects of lead acetate in male Wistar rats, which could be attributed to its polyphenol content and antioxidant properties.

ABSTRACT Background: Recent studies showed that Interleukin-8 (IL-8), activated cytokine immune response which plays an important role in the development of acute and chronic gastritis. Harmless anti-inflammatory therapeutic alternatives have been proposed, for example, the consumption of Sechium Edule Jacq. Swartz (chayote). Antioxidant (flavonoid) and cell regeneration (alkaloid) agents were found in chayote. This study aimed to determine the effect of chayote Sechium Edule Jacq. Swartz extracts on the level of IL-8 in Wistar rats with aspirin- induced gastritis. Subjects and Method: This was a randomized controlled trial (RCT) conducted at the laboratory of Mathematics and Natural Science, Universitas Sumatra Utara from January to February 2020. A total of 35 male Wistar rats was selected for this study and randomly allocated into 7 groups: (1) Negative control; (2) Positive control; (3) 100 mg/ kg BW chayote ethanol extract ; (4) 200 mg/kg BW chayote ethanol extract; (5) 100 mg/ kg BW chayote ethyl acetate fraction; (6) 200 mg/kg BW chayote ethyl acetate fraction; and (7) 20 mg omeprazole. The rats in positive control and treatment groups were induced with aspirin (200mg/ kg BW). The negative control group received no intervention. The dependent variable was level of IL-8 measured by ELISA. The independent variables were treatment status. The data were analyzed by One Way Anova and post hoc test. Results: The mean differences of IL-8 level were not statistically significant between study groups (p= 0.327). Mean of IL-8 level was higher in positive control group (Mean= 160.80; SD= 6.90) than in negative control group (Mean= 141.20; SD= 10.98). The lowest IL-8 level was in 100mg/ kg BW chayote ethanol extract group (Mean= 149.94; SD= 40.4), followed by 200mg/ kg BW (Mean= 152.4; SD= 30.73) and 100mg/ kg BW (Mean= 164.60; SD= 25.04) chayote ethyl acetate fraction groups, 20 mg omeprazole group (Mean= 170.60; SD= 21.58), and 200 mg/ kg BW chayote ethanol extract group (Mean= 176.80; SD= 10.98). Conclusion: The low dose (100mg/ kg BW) chayote ethanol extract has the most potential antiinflammation effect on in vitro gastritis with the lowest IL-8 level of all doses of chayote ethanol extract, chayote ethyl acetate fraction, and omeprazole.

Background: The process of wound healing is influenced by various factors such as age, hormones, and wound care. Wound care is done to accelerate wound healing which can be done by various methods, one of them is traditional care. Traditional wound care can use medicinal plants. Rhodomyrtus tomentosa is a medicinal plant that has an antioxidant, anti-inflammatory, antitumor and antibacterial content. Thus this study aims to evaluate the effectiveness of the antiseptic solution of the Rodhomyrtus tomentosa leaf extract on wound healing in male Wistar rats. Method: this research is pure experimental research with post test only control group design. Thirty male white rats were divided into five groups, namely negative control, positive control, Rhodomyrtus tomentosa leaf extract 15%, 30%, and 60%. Rhodomyrtus tomentosa leaf extraction was carried out by maceration method with 70% ethano solvent. The extraction results are divided into 3 concentrations (15%, 30% and 60%). The wound healing process was evaluated by measuring the length of the wound manually from 0 to 10 days in each group. Meanwhile, the number of fibroblast cells was calculated through hematoxylin eosin (HE) staining and observed using an Olympus CX41 microscope with a 10x magnification and objective lens magnification in 3 fields. Result: There was a significant difference in the reduction in wound length (p =< 0,000) between the five experimental groups (Rhodomyrtus tomentosa leaf extract solution 15%, 30% and 60%, negative control and positive control. Solution of rhodomyrtus tomentosa leaf extract accelerated the increase in the number of fibroblasts compared to the negative control group (p = 0.003), but did not make a difference (p = 0.403) with the positive control group. Rhodomyrtus tomentosa leaf extraction solution had the same microscopic effect on the number of fibroblasts with a positive control group given 0.9% NaCl solution. Conclusion: There was a significant difference in the number of fibroblasts between all groups, but no difference in wound healing length.

Coronary heart disease (CHD) is the cause of 7,3 million death globally in 2008. The main pathophysiology process that leads to CHD is atherosclerosis which is caused by high LDL cholesterol level. The aim of this study was to explore bay leaf and celery leaf infusion effect on reducing LDL cholesterol level in dyslipidemic rat model. The type of this study was true experimental research using wistar rat (Rattus novergicus) as the sample. The rats were induced by high fat diet and PTU for two weeks then each of the group were given either bay leaf infusion, celery leaf infusion, simvastatin (positive control), or aquadest (negative control) for a week. The measurement of LDL level used Friedewald formulation. Data was analyzed using paired sample t test and one way ANOVA. As the result there was a significance reduction on LDL level after treatment with bay leaf (p=0,013) and celery leaf infusion (p=0,035) but there was no significance difference between groups (p=0,293). It was concluded that bay leaf and celery leaf infusion could reduce the LDL level in dyslipidemic wistar rat but there was no difference on the capability of the two different leafs on reducing LDL level. Keywords: dyslipidemia, LDL, bay leaf, celery leaf, wistar rats
