Abstract
Stachytarpheta jamaicensis (SJ) is one of the plants that being used as alternative in traditional treatments that possess medicinal properties. SJ has been found to exhibit anti-inflammatory activity in acute and chronic models of inflammation, and thus protects the liver. However, its effect on liver and kidney injury induced by lipopolysaccharide remains unclear. To examine the protective effects of SJ on liver and kidney of LPS-induced endotoxemia in ICR mice via determination of lipid peroxidation and histology assessment. A total of 18 male ICR mice (20-30g, 6-8 weeks) were divided into six groups. Control (CTR) and negative control (NEG) groups received normal saline, while treatment groups received dexamethasone (DEX; 5 mg/kg bodyweight (BW)), and ethyl acid extract of SJ (10,100, and 150mg/kg BW) respectively, for seven days consecutively. On day 8, all groups (except control group) were injected with lipopolysaccharides (LPS; 1mg/kg BW) intradermally. After 1 hour of LPS injection, the mouse were euthanized and livers were excised, weighed and kept for assessment of thiobarbituric acid reactive substances-malondialdehyde (TBARs-MDA) assay and histology assessment by haematoxylin-eosin staining. The SJ supplementation slightly decreased the lipid peroxidation in liver as compared to NEG group. In histology observation, the higher dosage of SJ at 150mg/kg BW improved the structure of hepatocytes and less congestion of central vein. In lesion score of the liver, SJ150 has significantly lower of lesion score compared to NEG. Whereas, in kidney tissue, the supplementation of SJ at 100 and 150 mg/kg BW significantly decreases lipid peroxidation level compared to NEG. In kidney lesion score, SJ150 was significantly lower by 55.32% compared to NEG. Overall, supplementation of SJ in LPS-induced endotoxemia in ICR mice may have potential in lowering lipid peroxidation and preventing liver and kidney injury. Further assessment should be done to explore the mechanisms of SJ in preventing the inflammatory mediators induced by LPS that leads to liver and kidney injury.
