Introduction: The matoa plant (Pometia pinnata) leaves can be used to treat hypertension. Matoa leaves are thought to have antihypertensive activity because they contain flavonoids. These flavonoids can reduce blood pressure that is modulated by the renin-angiotensin-aldosterone system (RAAS). It is suspected that matoa leaves have antihypertensive activity as they contain quercetin which is a compound that is presumed to be an angiotensin-converting enzyme (ACE) inhibitor. Aims: This study aims to determine which extracts and fractions from matoa leaves are able to decrease angiotensin I levels. Methods: The extraction was done by maceration with 96% ethanol solvent and fractionated by a liquid method using an n-hexane fraction solvent, an ethyl acetate fraction, and a water fraction. In this study, 21 male Wistar rats were used as test animals and divided into seven groups: Group I was the normal control, group II was the negative control (CMC-Na 1%), group III was the positive control (Irbesartan), group IV was given matoa leaf extract with 60 mg/200g body weight ratio, Group V was given 2.34 mg/g fraction of n-hexane, Group VI was given ethyl acetate fraction 9.54 mg/200g ethyl acetate fraction, and Group VII was given water fraction 7.98 mg/200g water fraction. The data obtained was analysed using the Shapiro-Wilk test, the Levene test, and analysis of variance (ANOVA). Results: The results showed that the angiotensin I levels induced by angiotensin II were more significant (p < 0,05) than those in the normal and negative groups. The ethyl acetate fraction showed a 23.6% decrease in angiotensin I level, which was close to the 24.8% decrease in the positive group. The extract from the matoa leaves showed a 17.2% decrease in angiotensin I levels which were close to the 20% decrease in the positive group.

<p>Hypercholesterolemia is a risk factor for atherosclerosis and vascular diseases. Medicinal plants with different content of secondary metabolites such as polyphenols and flavonoids are natural sources to cope hypercholesterolemia. This study aimed to determine the effect of ethyl acetate fraction of piladang leaves (<em>Solenostemon scutellarioides</em> (L) Codd) on serum cholesterol levels in hypercholesterolemic male rats. Rats were divided into 6 groups, each consisting of 6 animals: group I (negative control), group II (positive control), group III, IV and V were each given fraction of ethyl acetate doses respectively 100, 250 and 500 mg/kg and group VI (simvastatin as a comparator). Measurement of serum cholesterol levels were conducted with CHOD-PAP method using a photometer 5010. Result showed ethyl acetate fraction affects cholesterol levels of experimental animals with a lower value than the positive control. According to statistics of one way ANOVA followed by the Duncan test method SPSS 17 showed no significant differences (p&gt; 0.05) on cholesterol levels in all given doses of ethyl acetate fraction. Group III(a dose of 100 mg / kg) was probably the most effective in lowering the blood cholesterol levels of experimental animals.</p>

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.

PURPOSE: To compare body weight and length, heart weight and length, heart-to-body weight ratio, glycemia, and morphometric cellular data of offspring of diabetic rats (ODR) and of normal rats (control). METHODS: Diabetes was induced in 3 pregnant Wistar rats, bearing 30 rats, on the 11th day after conception by intraperitoneal injection of 50 mg/kg of streptozotocin. Six normal pregnant Wistar rats, bearing 50 rats, made up the control group. Morphometric data were obtained using a scale for the weight, length, heart and body measurements. Morphometric cellular data were obtained by a computer assisted method applied to the measurements of myocytes. Statistical analysis utilized Student's t-test, ANOVA and Levene test. RESULTS: Control offspring had greater mean body weight and length than offspring of diabetic rats (p < 0.001). Heart weight and length and heart-to-body ratios of newborn rats differed between groups at birth (p < 0.001), but showed no difference at 21 days. Mean nuclei area and perimetric value of the myocytes decrees throughout the first 21 days of life (p < 0.01) in the diabetic group. CONCLUSIONS: Heart hypertrophy on the offspring of diabetic rats at birth was demonstrated by the significant difference between the groups. After the eleventh day, no difference was found, which confirmed regression of cardiomegaly. The significant difference between the first and the 21th day of life, for nuclei area feature, demonstrate regression of cardiac hypertrophy in the offspring of diabetic rats.

Background: Binjai (Mangifera caesia) is a herb derived from South Kalimantan possessing antioxidant properties which promote wound healing inhibiting oxidation radicals. The natural antioxidants present in binjai leaves can be extracted by fractionation. Purpose: This study aimed to analyze the antioxidant activity of ethyl acetate fraction in 96% ethanol extract of binjai leaf. Methods: The study constituted a pure experimental study incorporating a post-test design with only random sampling technique consisting of two groups, namely; an ethyl acetate fraction as the treatment group and ascorbic acid as the positive control group. The leaves were treated in accordance with the soxhlet method and subsequently fractionated to extract ethyl acetate fraction. This was used to measure antioxidant activity with DPPH radical damping method using a UV-Vis spectrophotometer. A linear regression calculation was performed with a standard curve to quantify the IC50 value, before the ethyl acetate fraction underwent a qualitative test of secondary metabolite. Results: An independent t-test indicated significant differences between groups, an average value of IC50 in ascorbic acid of 13.812 ppm with 0.996 linearity and a fraction of ethyl acetate 38.526 ppm with a linearity of 0.999. In contrast, at this linearity value ascorbic acid and ethyl fraction acetate demonstrate a very high linear connection between concentration and inhibition. A secondary metabolite test conducted on the ethyl acetate fraction produced positive results for flavonoid, tannins, and phenol. Conclusion: Based on the IC50 parameters, the fraction of ethyl acetate in 96% ethanol extract of binjai leaf produces very strong antioxidant activity in the content of the compounds in the fraction, namely: flavonoid, tannins and phenol.
