Abstract

Diabetic nephropathy is one of the diabetes complications attacking kidney leading to kidney damage. Hyperglycemia accompanying DM causes the increase of Ad-vanced Glycation End-Product (AGE) and Receptor Advanced Glycation End-Product (RAGE) activity, then develop kidney damage and other diabetes compli-cations. The study aimed to investigate the effect of black soybean, purple sweet potato, or their combination on the expression of AGE, RAGE, and kidney necro-sis T2DM model rats. The rats were given with high-calorie diet for five weeks and then injected with a low dose of streptozotocin (30 m/kg Body Weight) in intraperitoneal. DM rats were divided into: normal, K- (T2DM), K+ (T2DM + glibenclamide 0.6 mg/kg body weight), P1 (T2DM + black soybean), P2 (T2DM + purple sweet potato), and P3-5 Combination 1-3 (T2DM + combination of black soybean and purple sweet potato in ratio of 1 : 3, 2 : 2, and 3 : 1). DM rats were then given the treatments for thirty days. The effect of black soybean, purple sweet potato, or the combination of both was evaluated through the expression of AGE, RAGE, and necrosis of renal tubules. The changes in renal tubules histological characteristics were evaluated using hematoxylin-eosin (HE) staining. Immuno-histochemistry analysis of renal tubules was to evaluate AGE-RAGE expression after the treatments. The research results indicated that there was a significant dif-ference from the combination of black soybean and purple sweet potato in reduc-ing AGE, RAGE, and renal tubules necrosis. The BSB and PSP combination ratio of 1:1 was able to improve renal tubules, decrease the expression of AGE and RAGE towards near normal. The combination of black soybean and purple sweet potato could be used as one of the alternatives to improve kidney damage in dia-betic nephropathy.

Abstract

Staphylococcus aureus is gram-positive bacteria that often infect the skin. S. aureus has been experiencing resistance to several antibiotics. One of the solutions to overcome the resistance is by using garlic that is believed by the society can overcome bacterial infection. The study aimed to find out the influence of the variation in concentration of local single clove garlic essential oil used on the inhibition and damage of morphological structure of S. aureus bacteria. The inhibition test was conducted using disc diffusion method. The experiment groups consisted of  1% DMSO as negative control, vancomycin 30µg/ml as positive control and single clove garlic essential oil (25 mg/ml, 50 mg/ml, 75 mg/ml and100 mg/ml) as treatment groups. The diameter of inhibition zone was measured using calipers. The morphological damage of the bacterial cells can be seen using Scanning Electron Microscopy (SEM) with magnification of 25000x. The result of Kruskal-Wallis test analysis indicated that the extract of local garlic essential oil has inhibitory activities against S. aureus bacteria (P0.05). The damage to the morphological structure of bacterial cells with the administration of 30 µg/ml vancomycin was equal to 100 mg/ml single clove garlic essential oil extract. Single clove garlic essential oil can be used as an alternative treatment for skin infection diseases by inhibiting S. aureus growth.

Abstract

Infeksi nosokomial yang disebabkan oleh bakteri Pseudomonas aeruginosa menjadi sulit dalam terapi pengobatan, hal ini disebabkan karena penularan infeksi yang begitu cepat dan sifat resistensinya terhadap antibiotik, sehingga untuk mengatasi hal tersebut diperlukan suatu pengembangan pengobatan alternatif yang berkhasiat sebagai antibakteri yang berasal dari bahan alami yaitu tumbuh-tumbuhan salah satunya adalah bawang tunggal. Bawang tunggal mengandung senyawa organosulfur salah satunya adalah minyak atsiri yang di dalamnya terdapat allisin, alliin dan ajoene (Lestari dan Rifai., 2017). Penelitian ini bertujuan untuk mengukur daya hambat ekstrak minyak atsiri bawang tunggal terhadap pertumbuhan bakteri Pseudomonas aeruginosa secara in vitro dengan metode difusi cakaram dan kerusakan bakteri diamati berdasar profil scanning elektron mikroskop. Konsentrasi ekstrak minyak atsiri yang digunakan yaitu 100mg/ml, 75mg/ml, 50mg/ml, 25mg/ml, Ceftazidime 30µg/ml. Hasil uji ANAVA tunggal diketahui (p < 0,05) yang menunjukkan adanya nilai yang signifikan pada masing-masing perlakuan ekstrak minyak atsiri bawang tunggal dalam menghambat pertumbuhan bakteri Pseudomonas aeruginosa. Kerusakan bakteri diamati dengan Scanning Elektron Mikroskop menunjukkan bakteri mengalami pengerutan, sel menipis dan lisis. Simpulan penelitian yaitu ekstrak minyak atsiri bawang tunggal dapat menghambat pertumbuhan bakteri Pseudomonas aeruginosa dengan kriteria kuat yaitu pada konsentrasi 100mg/ml.
