Silva CB, Fassini PG, Ramalho LNZ, da Conceição EC, Zordan AJCM, Carlos D, Suen VMM. Curcuma supplementation in high-fat-fed C57BL/6 mice: no beneficial effect on lipid and glucose profile or prevention of weight gain. Eur J Nutr 2019; 59:93-102. [PMID: 30604178 DOI: 10.1007/s00394-018-1887-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Accepted: 12/19/2018] [Indexed: 01/22/2023]
Abstract
PURPOSE This experimental study investigated the effects of curcuma supplementation on weight gain, Body Adiposity Index, glucose and lipid profile, and liver and pancreas histology in C57BL/6 mice fed with a high-fat diet. METHODS 40 animals were separated into four groups: standard diet (SD), standard diet plus curcuma (SD + C), high-fat diet (HFD), and high-fat diet plus curcuma (HFD + C). Curcuma dose was 8 mg/animal/day. Histological and biochemical analyses were performed at the end of the experimental period. RESULTS Curcuma prevented weight gain, despite a higher food intake, and increased brown adipose tissue weight only in mice receiving standard diet. However, these changes were not observed in HFD + C group. The groups that received curcuma (SD + C and HFD + C) showed a pancreas with diffuse macro- and microgoticular steatosis. CONCLUSIONS Curcuma supplementation did not prevent weight gain or improved glucose and lipid profile in mice receiving high-fat diet. Furthermore, there was evidence of possible curcuma toxicity in the pancreas of C57BL/6 mice. The implications of these findings on humans still need to be investigated.

Abstract
ABSTRACT This study analyzed the physicochemical and photophysical properties of essential oil of Curcuma longa and its angiogenic potential. The results showed that curcumin is the main fluorescent component present in the oil, although the amount is relatively small. The experimental chorioallantoic membrane model was used to evaluate angiogenic activity, showing a significant increase in the vascular network of Curcuma longa and positive control groups when compared to the neutral and inhibitor controls (P <0.05), but no significant difference was found between Curcuma longa essential oil and the positive control (P >0.05). Histological analysis showed extensive neovascularization, hyperemia and inflammation in the positive control group and Curcuma longa when compared to other controls (P <0.05), characteristic factors of the angiogenesis process. In conclusion, Curcuma longa oil showed considerable proangiogenic activity and could be a potential compound in medical applications.
