Objective: The present study was undertaken to evaluate the possible ameliorative role of curcumin, capsaicin and their combination against lipopolysaccharide (LPS) induced hepatic toxicity in mice. Methods: Animals were distributed into five experimental groups: Normal control, vehicle control, curcumin, capsaicin and combined curcumin and capsaicin treatment groups respectively, for 7 days prior to LPS induced liver toxicity (3 mg/kg b.w. in saline). Hepatoprotective effect of individual and combined spice principles were evidenced by the measurement of serum marker enzyme activities such as, SGPT, ALP and TB and it was further confirmed by histopathological observation of liver tissue section. Results: The administration of LPS increased serum nonspecific enzymes (SGOT; 174.2±3.79 IU/L, SGPT; 124.0±3.14 IU/L, ALP; 320.15±3.88 IU/L and total bilirubin level; 2.32±1.23 mg/dL), however dietary curcumin and capsaicin decreased the activities of these non-specific serum enzymes including total bilirubin indicating amelioration of the severe LPS induced hepatotoxicity, while the combined spice principles were more significant as shown by the levels of enzymes activities SGOT; 89.9±1.39 IU/L, SGPT; 85.9±1.83 IU/L, ALP; 138.4±2.05 IU/L including total bilirubin level; 0.86±0.03 mg/dL. Conclusion: Dietary curcumin and capsaicin individually are protective to LPS induced hepatotoxicity, the beneficial effect was found to be more when the two compounds were fed in combination.

Objective:The current study aimed to evaluate the anti-inflammatory potency of combined curcumin and capsaicin against lipopolysaccharide (LPS) induced organ damage in mice. Methods: Adult male albino mice were distributed into five experimental groups for treatment with olive oil, LPS, curcumin, capsaicin and their combination, respectively, for 7 days prior to LPS induced inflammation. At the end of the experiment, blood samples were collected and used for the analysis of serum non-specific enzymes including serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), total bilirubin (TB), urea, creatinine and sugar, while the organ homogenates were subjected for the evaluation of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutothione S transferase (GST), nitric oxide (NO); lipid peroxidation (LPO) and it was further confirmed by histopathological study of different organs. Results and Conclusion: Curcumin, capsaicin and their combination had shown significant restoration of non-specific serum enzymes, antioxidant enzymes and attenuated inflammatory cells infiltration thereby preventing tissue/organ damage in LPS-challenged mice. However, the protective effect was found to be more when the two compounds were fed in combination. This beneficial potency of combined spice treatment is may be due to the contribution of diversified active moieties of curcumin and capsaicin in combination compared to individual molecules.
