Introduction: Roselle (Hibiscus sabdariffa L.) calyces possess natural antioxidants that may provide therapeutic benefits. This study aimed to investigate the protective effects of Roselle calyx water extract against isoniazid (INH) and rifampicin (RIF) induced liver and renal toxicities.Methods: Male Wistar rats (150-250 g) were designated into five groups: control group, INH-RIF group that was treated with INH-RIF at the toxic doses (50-100 mg/kg for 4 weeks, followed by 100-200 mg/kg for 2 weeks), and Roselle groups that were treated daily with Roselle extract at the doses 62.5, 125, and 250 mg/kg, respectively prior to INH-RIF administration. Blood samples were withdrawn weekly for 6 weeks before removing rats’ livers and kidneys for tissue malondialdehyde (MDA) and histopathological analysis.Results: The results showed all rats in the INH-RIF group experienced marked elevations of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, creatinine, and tissue MDA levels compared to the controls (P<0.05). In contrast, these biomarkers were maintained at near-normal levels in Roselle extract groups. Significant inflammation and cellular degeneration were found in the liver and renal tissues of the INH-RIF group, which were noticeably reduced with Roselle extract pre-treatment at the dose of 250 mg/kg.Conclusion: It is concluded that Roselle calyx extract can provide protection against liver and renal toxicities induced by INH-RIF administration in rats.

Landslides that hit Indonesian territory caused various problems. Every landslide disaster will cause problems such as economic paralysis, environmental damage and also cause various diseases. Geographically, Samaenre village, Mallawa District, Maros Regency, South Sulawesi with high rainfall and an average temperature 32°C with rainy season approximately 8 months. Landslides often occur in Indonesia, especially in areas with steep slopes. Landslides and stagnant water also still have the potential to occur due to heavy rains. Samaenre area has the potential for landslides and waterlogging. The purpose of this activity is to increase public knowledge about the potential for landslides, problems that can arise after landslides and how to deal with post-landslide health problems. The community service activities were attended by 24 people and the counseling material could be delivered by all of the service teams so as to increase community knowledge about tackling health problems in post-landslide conditions.Keywords: Landslides, Samaenre village, health problems..

Liver is one of the most vital organs that functions as a center for metabolism. One of the diseases that disrupt liver function with a high prevalence is NAFLD (Non Alcoholic Fatty Liver Disease). NAFLD is characterized by increased intracellular triglyceride accumulation. Increased lipid peroxidation can lead to Non Alcoholic Steato Hepatitis (NASH) and cirrhosis which induces proinflammatory cytokines. Alpha lipoic acid (ALA) is an antioxidant that has been widely used in treating metabolic syndrome. Based on several previous studies. ALA may be useful for the treatment of NAFLD by targeting various pathways in the development of NAFLD. The study divided animals into five groups as standard feed; high fat diet (HFD); HFD and ALA 100 mg/kg BW i.p .; HFD and ALA 100 mg/kg BW i.p also repaired -fed; HFD and repaired -fed. Based on the results of the study, it can be concluded that ALA as an antioxidant can improve liver cell histopathology in NAFLD rat induced high fat diet.

Antituberculosis is the most liver damage causes. Rifampicin and Isoniazide, in combination, are toxic compounds. Isoniazide and rifampicin metabolits causes lipid peroxidation. The hepatoprotective effect of rosella calyx water extract on liver damage induced with Isoniazide-rifampicin evaluated by examination of malondialdehid levels in the liver organ. 25 male wistar rats divided into 5 groups, ie group I (INH-rifampicin + rosella water extract 250 mg/kgBW), group II (INH-rifampicin + rosella water extract 125 mg/kgBW), group III (INH-rifampicin + rosella water extract 62.5 mg/kgBW),  group IV (healthy control) and group V (Isoniazide-rifampicin). MDA liver levels were analyzed after 35 days of treatments. The test results of each group are, group I has mean MDA levels 0.023912 + 0.011 mg/ml, group II 0.023526 + 0.009 mg/ml, group III 0.027168 + 0.007 mg/ml group IV 0.03437 + 0.009 mg/ml and group V 0.236846 + 0.118 mg/ml. The kruskal-wallis test showed significantly value 0.008 (p 0.05) and Post hoc Mann U whitney test showed that group V was significantly different to group I, II, III, and IV (p = 0.008) respectively, roselle extract can be used as a hepatoprotector antioxidant to improve the tuberculosis drug consumer quality of life through improved health by lowering lipid peroxidation that causes liver damage.
