Antidyslipidemic Effect of Fenugreek Seeds Powder against Sodium Fluoride-Induced Dyslipidemia in Male Rabbits

Abstract

Background: Although fluoride is everywhere in the environment, the major environmental sources of population exposure to elevated levels of fluoride are water, food, beverages, air, food supplements, and dental products. Fluoride is a well determined non-biodegradable and moderate pollutant, which at high levels causes serious health problems. Objectives: The present study aimed to evaluate the anti-dyslipidemia effect of fenugreek seeds powder against dyslipidemia induced by sodium fluoride in male rabbits. Materials and Methods: This study included twenty-four adult male rabbits, which were divided into 4 groups, 6 rabbits for each. Group I (control group): Animals were provided with tape water and fed with normal diet for 30 days. Group II (Fenugreek seeds powder group): Fenugreek seeds powder was given to rabbits in food at a dose of 10 g per kilogram of diet weight/kg of body weight/day for 30 Days. Group III (sodium fluoride group): Rabbits were injected intraperitoneally with sodium fluoride at a dose of 15mg/kg of body weight/day for 30 consecutive days. Group IV (Sodium fluoride/fenugreek co-administered group): Fenugreek seed flour was added at a rate of 10 g per kilogram of diet weight, and rabbits were injected with intraperitoneally with sodium fluoride at a dose of 15mg/kg of body weight/day for 30 consecutive days. After thirty days, blood samples were taken for biochemical analysis. Biochemical analyzes were performed to measure of the serum concentrations of cholesterol, triglycerides, HDL-C, LDL-C, and VLDL-C in all groups. Results: The results of the study showed that the treatment of male rabbits with sodium fluoride resulted in a significant increase (P<0.01) in the serum concentrations of cholesterol, triglycerides, LDL-C, and VLDL-C, and a significant decrease was observed (P<0.01) in serum HDL-C compared with the control group. In rabbits received fenugreek seeds powder only, the serum triglycerides and VLDL-C were significantly (P<0.01) decrease and the serum HDL-C was significantly (P<0.05) increase compared with the control group. A significant decrease (P<0.01) was observed in serum cholesterol, triglycerides, LDL-C, and VLDL-C, and a significant increase was observed (P<0.01) in serum HDL-C in rabbits treated with sodium fluoride and fenugreek seeds powder compared with the sodium fluoride group, but these measurements did not reach normal levels in the control group. Conclusion: The results showed that injection of rabbits with sodium fluoride led to serum dyslipidemia, and the injection with sodium fluoride and treatment of fenugreek seeds powder alleviate dyslipidemia induced by sodium fluoride. The use of fenugreek seeds powder by humans can be considered beneficial in the alleviation of dyslipidemia. It is recommended that humans exposed to sodium fluoride should be advised to take Fenugreek seeds powder as a rich source of antioxidant to prevent serum dyslipidemia induced by sodium fluoride. Further studies are necessary to elucidate exact mechanism of the antidyslipidemic effect of Fenugreek seeds powder and potential usefulness of Fenugreek seeds powder as a protective agent against sodium fluoride induced dyslipidemia in clinical trials.
