Background: Diabetes mellitus (DM) is the seventh leading cause of death in the world (the occuring rate has reached 400 million people). Type2 DM is caused by the body cells’ inability to respond normally to insulin (insulin resistance). Homeostatic Model Assessment-Insuline Resistance (HOMA-IR) is a calculation method which function is to measure the body insulin resistance. Diabetes mellitus can cause lipid metabolism disorders (dyslipidemia) resulting in an increased level of LDL cholesterol and decreased HDL cholesterol. The apoprotein B/apoprotein A-I ratio is the result of comparisons of apoprotein B (LDL protein constituent) and apoprotein A-I (HDL protein constituent). The apo B/apo A-I ratio represents a balance between LDL cholesterol (atherogenic) and HDL (anti-atherogenic). It is astrong signifier in predicting heart disease. Purpose: This study aim to determine the correlation between the apoprotein B/apoprotein A-I ratio with HOMA-IR in patients with type 2 diabetes mellitus. Methods: Observasional, consecutive, 100 people with type 2 diabetes mellitus who is examined in apoprotein B, apoprotein A-I test that calculating the ratio in which ratio are calculated, as well as HOMA-IR in Parahita Clinical Laboratory Surabaya. This study uses Pearson correlation test method with SPSS 22.0 for Windows program. Results: The result of Pearson correlation test between apoprotein B/apoprotein A-I ratio with HOMA-IR in 100 samples is a strong and significant correlation value (r=0,610, p

Background: One of the most common health problems is infectious diseases. Infectious disease can be caused by bacteria. There were two groups of bacteria based on the staining, Gram-positive and Gram-negative bacteria. Purpose: Antibiotics are the main therapy used in the incidence of bacterial infections. But over time, some antibiotics became resistance. Several studies have shown that garlic has an antibacterial effect. The content of allicin, ajoene, saponins, and flavonoids is found in garlic which has antibacterial properties. The antibiotic activity test of garlic was carried out on the bacteria Streptococcus pyogenes and Pseudomonas aeruginosa. The goal of this study is to investigate the antibacterial effect of Allium sativum L. extract against Streptococcus pyogenes and Pseudomonas aeruginosa. Methods: Garlic extract was made using the maceration method using 96% alcohol as the solvent. Tube dilution method elected to observe garlic antibiotic activity. This test aims to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). There were eight different concentration used, i.e. 2 grams/ml, 1 gram/ml, 0.5 gram/ml, 0.25 gram/ml, 0.125 gram/ml, 0.0625 gram/ml, 0.03125 gram/ml, and 0.015625 gram/ml. Replication is done three times. Results: In this experiment, the extract produced was turbid that MIC could not be determined and there was no momentous differentiation between before and after treatment. There was no growth of Streptococcus pyogenes in 1 gram/ml and Pseudomonas aeruginosa in 0.5 gram/ml. This number indicates the MBC for each bacteria. Conclusion: Garlic (Allium sativum L.) has an effect of bactericidal activity, it can perform as an antibacterial for Streptococcus pyogenes and Pseudomonas aeruginosa. Garlic extract was more effective for Pseudomonas aeruginosa than Streptococcus pyogenes.
