Antiobesity and antihyperlipidemic effect of Ixora coccinea on Triton X-100 induced hyperlipidemia in rats: An approach to evaluate asymmetrical temperature distribution analysis using thermography / 中草药·英文版

ABSTRACT

Objective: Obesity and hyperlipidemia is the major cause of many pathological diseases with an increase side effects using allopathic drugs. The present study focuses on the effect of Ixora coccinea on Triton X-100 induced hyperlipidemia in rats and associated complications. Methodology: In vitro radical scavenging activity of I. coccinea was assessed using DPPH, FRAP and hydrogen peroxide. In vivo antiobesity and antihyperlipidimic activity of I. coccinea was tested in Triton X-100 induced hyperlipidemic rats and assessed for its biochemical parameters in blood and tissue samples. The relationship between physiological responses and regulation of body temperature was investigated by using animal surface temperature images captured with infrared camera. Results: The results of mineral analysis, antioxidant, total flavonoid and phenolic content represented high amount of mineral and had the potential to scavenge free radicals tested with DPPH, FRAP and hydrogen peroxide radicals with dose dependent activity. The highest activity was observed in aqueous extract, DPPH with 71.5% inhibition, FRAP with 56.8%, H2O2 with 33% activity at 100 µg/mL concentration. Triton X-100 induced hyperlipidemic rats when treated with I. coccinea aqueous extract showed significant activity by regulating the biochemical parameters and maintaining the lipid profile by decreasing TC, LDL-C, VLDL-C, TG and improving HDL-C levels. Similarly, the elevated levels of creatinine, urea, uric acid, AST, ALT, ALP due to induction of hyperlipidemia, were brought back to near normal levels after treatment with I. coccinea. The levels of tissue anti-oxidants enzymes like SOD and CAT were also found to be improved in treated I. coccinea groups. The whole body asymmetrical temperature distribution analysis showed that significant decreases in temperature was observed in obesity induced groups but a gradual increase in temperature (2%–5%) was observed after treatment. Conclusion: Thus, the results indicated that I. coccinea can be a drug of choice to decrease the risk of complications associated with hyperlipidemia and obesity.
