Abstract

Triglyceride (TG) is a simple and the main lipid of the daily diet. Nowadays, TG is emerging as an independent risk factor for cardiovascular disease, and increasing clinical data that indicate a high level of this simple lipid in serum may alert and play a role in liver impairment. Red yeast rice (RYR) reduces serum TG in human and animals. The rice is widely used as a natural inhibitor of HMG-CoA reductase to correct serum cholesterol level. Bioactive components of the rice are well known to have antioxidant properties. This study examined whether RYR protects hepatocytes by evaluating the serum AST-ALT, HDL-Cholesterol (HDL-C), TG levels, and the number of liver foam cells in hypertriglyceridemic rats. Twenty male Wistar rats were grouped into 5. Four groups received a high-fat diet (HFD), 40 g/animal/day for 60 days to induce hypertriglyceridemic condition. Along with the HFD treatment, three groups received 108, 54, and 27 mg/kgBW/day of RYR, respectively. Two other groups received standard and only HFD diet, respectively. Intracardiac blood was collected for measuring AST and ALT using AST or ALT activity assay Kit, respectively, serum TG and HDL-C by Enzymatic Caloric Test.  Hematoxylin-Eosin–stained 4µmm thick slices of liver tissues were prepared to count foam cell number by a light microscope with 400x magnificence. Data were analyzed using the Kruskal Wallis continued by the Mann Whitney U test. The p values of < 0.05 were considered to be significant. The present study found that 108, 54, and 27 mg/kgBW/day of RYR significantly decreased serum TG, HDL-C, AST, and ALT compared with those of hypertriglyceridemic rats receiving no RYR. The decreasing levels of the parameters were in relation to the doses of RYR. The doses of 108 and 54 mg/kgBW/day resulted in complete recovery of the liver tissues suffered from steatosis (p < 0.05). The RYR dose of 108 mg/KgBW/day completely corrects the serum HDL-C level. In conclusion, red yeast rice may have a potency to protect hepatocytes injuries due to hypertriglyceridemia.

Abstract

Background: There are many factors that govern growth and resistant of Salmonella typhi. A study had reported that the use of sodium benzoate caused antibiotic resistant. However, no study has directly evaluated the effect of sodium benzoate exposure on S. typhi sensitivity to chloramphenicol. The aim of this study was to evaluate the resistance or sensitivity of S. typhi to chloramphenicol after sodium benzoate exposure. Methods: The study was conducted in seven groups: three treatment groups (sodium benzoate insensitive S. typhi+8 µg/mL, 16 µg/mL, and 32 µg/mL of chloramphenicol), three positive control groups (sodium benzoate sensitive S. typhi+8 µg/mL, 16 µg/mL, and 32 µg/mL of chloramphenicol), and one negative control groups (sodium benzoate sensitive S. typhi+0 µg/mL of chloramphenicol). The effect of sodium benzoate exposure to S. typhi sensitivity to chloramphenicol was measured after 24 hours. Spearman test was used to analyzed this association. Results: In this study, we found that the average S. typhi growth in the treatment groups (A, B, C) was 445 CFU/mL, 385 CFU/mL, and 171 CFU/mL, respectively. While in the positive control group (D, E, F) was not obtained any S. typhi growth. Average S. typhi growth in the negative control group was 430 CFU/mL. Discussion: We found that sodium benzoate exposure inhibited S. typhi growth and affected S. typhi sensitivity to chloramphenicol (p < 0.05). In addition, we found that 32 µg/mL chloramphenicol had the highest mean difference value, so this showed that the dose 32 µg/mL of chloramphenicol had the best effectiveness of various treatment groups (p < 0.05). Conclusions: Sodium benzoate exposure can inhibit S. typhi growth and cause S. typhi resistant to chloramphenicol.
