EFEK PEMBERIAN MADU TRIGONA TERHADAP KADAR ALBUMIN TIKUS PUTIH YANG DIINDUKSI ATORVASTATIN

Honey has antioxidant activity that prevents oxidative stress due to high doses of atorvastatin. This study determines the effect of trigona honey provision on albumin levels of white rats given high doses of atorvastatin. Twenty-four white rats (Rattus norvegicus) were divided into 6 groups (n = 4), and each was subjected to different treatment for 5 weeks. One group was given two doses of atorvastatin 20 mg/kg for 3 weeks, followed by 40 mg/kg for 2 weeks. Group 1, normal control, received 0.5% NaCMC, group 2 - negative control  received atorvastatin, and group 3- honey control received 4.5 ml / kgBB of honey. Groups 4, 5, and 6 each were given Trigona honey at a doses of 1.5 ml / kgBB, 3 ml / kgBB, and 4.5 ml / kgBB, each with atorvastatin. The results showed that the highest albumin level was in the normal control of 2.83 mg/dl, while the lowest was in the negative control of 2.38 mg/dl. Furthermore, groups 3, 4, 5, and 6 had albumin levels of 2.55, 2.53, 2.63, and 2.53 mg/dl, respectively. Statistical analysis showed that there were significant differences (p 0.05) between negative controls and three groups of animals given trigona honey with atorvastatin induction. Therefore, the trigona honey did not have a preventive effect on changes in albumin levels in atorvastatin-induced rats.Keywords: atorvastatin, Trigona honey, albuminMadu memiliki aktivitas antioksidan yang mampu mencegah stress oksidatif yang diakibatkan oleh penggunaan atorvastatin dosis tinggi.

Pengaruh Suplementasi Madu Trigona Terhadap Parameter Fungsi Hati Dan Ginjal Tikus Albino (Rattus Norvegicus) Yang Diberikan Simvastatin: Effect of Trigona Honey Supplementation on Liver and Kidney Function in SimvastatinAdministered Albino Rats (Rattus Norvegicus)

Simvastatin is a drug acting on 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase enzyme leading to decrease of lipid level in plasma. Simvastatin is associated with pleiotropic effects such as cardioprotective, hepatoprotective, and nephroprotective effect. This study aimed to observe effect of supplementation of trigona honey on parameters of liver function (SGPT and SGOT) and kidney function (urea) in albino rats (Rattus norvegicus) given 40 mg/kg simvastatin. Twenty-four male albino rats were divided into 6 groups (n=4). Each group was administered different treatments for 15 days orally. Group I was put as health control without any treatment, group II was given sodium carboxymethylcellulose (1% b/v) as negative control, group III was given simvastatin at the dose of 40 mg/kg, group IV was administered simvastatin (40 mg/kg) and trigona honey (6.5% v/v), while group V and VI were administered simvastatin (40 mg/kg) and ubiquinone (1.43 mg/kg); and simvastatin (40 mg/kg), trigona honey (6.5% v/v), and ubiquinone (1.43 mg/kg), respectively. Upon the treatments, level of SGOT, SGPT, and ureum was determined. The data were analyzed by using Analysis of Variance (ANOVA) and Least Significant Difference tests (p=0.05). According to the analysis, it was concluded that supplementation of trigona honey in rats administered simvastatin showed significantly lower level of all parameters than groups of simvastatin and controls

Marine macrolides to tackle antimicrobial resistance of mycobacterium tuberculosis

Tuberculosis has become a major health problem globally. This is worsened by the emergence of resistant strains of Mycobacterium tuberculosis showing ability to evade the effectiveness of the current antimycobacterial therapies. Therefore, the efforts carried out to explore new entities from many sources, including marine, are critical. This review summarizes several marine-derived macrolides that show promising activity against M. tuberculosis. We also provide information regarding the biosynthetic processes of marine macrolides, including the challenges that are usually experienced in this process. As most of the studies reporting the antimycobacterial activities of the listed marine macrolides are based on in vitro studies, the future direction should consider expanding the trials to in vivo and clinical trials. In addition, in silico studies should also be explored for a quick screening on marine macrolides with potent activities against mycobacterial infection. To sum up, macrolides derived from marine organisms might become therapeutical options for tackling antimycobacterial resistance of M. tuberculosis.Directorate General of Higher Education, Ministry of Education, Culture, Research, and Technology, Indonesia | Ref. 020/E5/PG.02.00PT/202
