Antidiabetic and Renal Protective Properties of Berrycactus Fruit (Myrtillocactus geometrizans)
Rosalia Reynoso-Camacho,Paola Martinez-Samayoa,Minerva Ramos-Gomez,Horacio Guzma´n,Luis M. Salgado 한국식품영양과학회 2015 Journal of medicinal food Vol.18 No.5
Native plants are exceedingly valuable because they are sources of natural products with applications for the treatment of various diseases. Berrycactus fruit (Myrtillocactus geometrizans) has been consumed in Mexico since ancient times due to its sweetness. The hypoglycemic and antioxidant effects of this fruit were evaluated in streptozotocin-induced diabetic rats by replacing the drinking water with berrycactus juice (2 or 4 g/kg). After 4 weeks of treatment, the diabetic animals showed an improvement in their conditions, as reflected by diminished circulating glucose levels (up to 50%), diminished triglycerides (up to 67%), and diminished total cholesterol (up to 35%) compared with diabetic nontreated controls, and these effects were dose dependent. The dose of 4 g/kg produced the best results. The administration of the juice improved renal function and helped to restore normal levels of glutathione and glutathione S-transferase in the kidney. The expressions of two transcription factors that are relevant to normal functioning of the kidney changed due to the administration of the juice; compared to the diabetic nontreated controls, the level of nuclear factor kappa of B-cells diminished, and the total level of peroxisome proliferator-activated receptor gamma increased. The results of this study highlight the importance of the compounds that are present in berrycactus fruit as adjuvants in the treatment of diabetes and its renal complications.

Lycopene Improves Diet-Mediated Recuperation in Rat Model of Nonalcoholic Fatty Liver Disease

The aim of the present study was to evaluate the synergic effect of lycopene (LYC) treatment with a dietary control in a nonalcoholic fatty liver disease (NAFLD) model induced with a high-fat diet (HFD). Sprague–Dawley rats were fed during 4 weeks with a normal diet (ND·4w) or an HFD (HFD·4w) to produce an NAFLD model. Then, rats from the ND·4w group continued during 4 weeks with the same diet (ND·8w), and rats from HFD were fed during 4 weeks with an ND (HFD·4w+ND·4w) or an ND plus LYC (HFD·4w+ND+LYC·4w). LYC (20 mg/kg) was administered daily by gavage. ND and ND+LYC diets partially reverted the following alterations due to HFD: liver weight, serum low-density lipoproteins (LDL), hepatic total cholesterol (TC), and catalytic activity of hepatic superoxide dismutase, catalase, and glutathione peroxidase, as well as macroscopic and microscopic images of livers. A higher recuperation to reach normality was obtained with ND+LYC in: liver weight, hepatic TC, serum LDL, and, in some instances, macroscopic and microscopic images of livers. Failures to recovery with both NDs were observed for malondialdehyde level and serum aspartate aminotransferase activity. Taken together, the results from this study suggest the potentially protective role of LYC against NAFLD; however, more clinical trials are needed to support this idea.
