ABSTRACT
Thymoquinone (TQ), one of the active components of Nigella sativa exhibited to have many biological effects. Several beneficial effects of TQ such as its antidiabetic, antioxidant, anticancer, hypolipidemic, and anti-inflammatory activities have been recognized. The present review focuses on the findings of recent studies on the protective effects of TQ against cardiovascular diseases. In the current review, we additionally concluded that TQ may be therapeutically effective agents for controlling diabetes and hyperlipidemia by decreasing the oxidative stress and inflammatory responses.

ABSTRACT
Curcumin (CUR), the main phenolic composition in turmeric, shows preventive effects in various diseases. CUR is commonly found in the Curcuma species and historically applied in herbal medicine. Numerous studies have indicated that CUR possesses protective effects against toxic agents in the various animal tissues including the brain. This study found that CUR may be effective in nervous system problems induced by neurotoxic agents. However, due to the lack of information on human, more investigations are needed to determine the efficacy of CUR as an antidote matter. The current study aimed to critically review the recent literature data from 2014 to 2016 that regarding the therapeutic aspects of CUR versus neurotoxic agents-induced brain damage and its involved mechanisms.

ABSTRACT
BACKGROUND: Herbal medicine is widely used in the treatment of diseases like diabetes mellitus. We investigated the effects of guar gum in diabetic rats for the reduction of the risk of diabetes and cardiovascular disease. Dietary pattern emphasizing foods high in complex carbohydrates and fiber are associated with low blood glucose and cholesterol levels. MATERIALS AND METHODS: Diet containing 0%, 5%, 10% and 20% (w/w) guar gum was fed to diabetic rats for 28 days. Blood serum glucose, triglycerides, cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol levels, atherogenic index levels, body weights and food intake were monitored at 0, 7.14 and 28 days after induction of diabetes. RESULTS: In spite of the fact that diabetes elevated blood lipids in all rats after 14 days, the guar gum diet significantly decreased the serum concentration of cholesterol, triacylglicerols and LDL-C and atherogenic index. The most significant result in this study was the reduction of blood glucose in diabetic rats treated with the guar gum diet after 28 days versus non- and glibenclamide-treated rats. The gum promoted a general improvement in the condition of the diabetic rats in body weight and food intake in comparison with nontreated rats. CONCLUSION: The results of this research suggest that guar gum was significantly effective in comparison with glibenclamide in the treatment of hyperlipidemia and hyperglycemia in diabetes rats. Therefore, it may be suggested as a reliable fiber in diabetic regimes in diabetic patients.
