Abstract

One-third of the Indonesian population uses herbs for alternative medicine empirically. One of them is Kapulaga (Amomum cardamomum) which known as a spice and traditionally used for the treatment of rheumatic, fever, cough, sore throat, and mouth odor. The clinical use of herbs must be supported by scientific evidenced-based and its safety profile. The risk of exposure to a substance in humans can be identified through the toxicity tests on animals. The liver histopathological structure is one of the parameters of the acute toxicity test. This study to determine the acute toxicity of Kapulaga seeds extract (Amomum cardamomum) based on the liver histopathological structure of Wistar rats. The sample selection based on inclusion and exclusion criteria in the OECD 420 guideline. The research consisted of a preliminary and the main test. One rat was used in the preliminary test with an initial dose of cardamom seed extract 300 mg/kg BW and followed by a maximum dose of 2000 mg/kg BW after 48 hours. The main test used 10 rats that were randomly divided into control and treatment groups. Based on the result of the preliminary test, the treatment group was given a single dose of cardamom seed extract 2000mg /kg BW, whilst the control group was given distilled water. Observations of any toxic signs or dead were conducted every 30 minutes in the first 4 hours and continued once per day until 14thday. Assessment of the degree of liver damage was done using the liver damaged scoring and compared using the Mann Whitney test (α = 0.05). The average liver damage score of control and treatment groups is 0.96 ± 0,856 and 0.96 ± 0,604, respectively, and did not show any statistically significant differences (p>0,05). Kapulagaseeds (Amomum cardamomum) had no acute toxic effect based on the liver histopathological structure of Wistar rats.

Abstract

Introduction: Metabolic syndrome poses a risk for the development of atherosclerotic lesions, which are associated with various cardiovascular diseases. Moringa leaves are known for their antioxidant and anti-inflammatory properties. ICAM-1 serves as an early marker of atherosclerosis. This study aims to investigate how the dosage of ethanolic extract from Moringa leaves affects the expression of ICAM-1 in the aortic tissue of Wistar rats with metabolic syndrome. Methods: This study employed a laboratory experimental design with a posttest only control group. The research involved 30 Wistar rats, divided into five groups: the normal control group (G1), the positive control group (G2), and three experimental groups (G3, G4, and G5). The experimental groups (G3, G4, and G5) were induced with metabolic syndrome and administered ethanolic extract of Moringa leaves at doses of 150 mg/kg, 250 mg/kg, and 350 mg/kg, respectively. The expression of aortic ICAM-1 was evaluated using the Intensity Distribution Score (IDS) and analyzed using one-way ANOVA and Post-hoc Tukey HSD test. Results: Increasing the dosage of ethanolic leaf extract of Moringa oleifera reduces the IDS value of ICAM-1 in the aortic tissue of Wistar rats with a significance of p<0.05.. Conclusion: The higher dosage of ethanolic leaf extract from Moringa oleifera Lamk has the potential to decrease ICAM-1 expression in the aortic tissue of Wistar rats with metabolic syndrome. The author hopes that Moringa leaf extract can be utilized as a supplement to prevent the formation of atherosclerotic plaques and cardiovascular diseases resulting from atherosclerotic plaques, such as thromboembolism and stroke.
