Effect of Cinnamon and Turmeric Aqueous Extracts on Serum Interleukin-17F Level of High Fructose-Fed Rats.

BACKGROUND: Studies have indicated that extraweight and obesity induce chronic inflammation, which can lead to other diseases such as cancers. OBJECTIVE: To evaluate the effects of two weight-lowering and anti-inflammatory agents including cinnamon, and turmeric, on serum levels of interleukin-17 (IL-17) as a pro-inflammatory cytokine. METHODS: In this study, 64 rats were designated in eight groups. The control group received normal diet. The other groups were fed with normal diet plus high cinnamon (3 mg/ml), high turmeric (3 mg/ml), high-fructose solution (30%), fructose solution with low (0.15 mg/ml) and high doses (3 mg/ml) of cinnamon and turmeric three times per week. The serum level of IL-17F was measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: High fructose consumption led to an increase in the weight and serum level of IL-17. While, feeding with cinnamon and turmeric caused to decline weight but, surprisingly increased IL-17F levels. CONCLUSION: Although, some studies have showed that cinnamon and turmeric supplementation decreased IL-17F under the standard diet, in the presence of high fructose diet and extraweight their effects were reversed and caused an increase in serum level of IL-17F.

Effect of a phytogenic feed additive on performance, ovarian morphology, serum lipid parameters and egg sensory quality in laying hen.

This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg(-1) phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. The results of experiment have shown that egg weight was increased by supplementation of 12 g kg(-1) feed additive whereas egg production, feed intake and feed conversion ratio (FCR) were not significantly affected. There were no significant differences in egg quality parameters by supplementation of phytogenic feed additive, whereas yolk trimethylamine level was decreased as the feed additive level increased. The sensory evaluation parameters did not differ significantly. No significant differences were found in serum cholesterol and triglyceride levels between the treatments but low- and high-density lipoprotein were significantly increased. Number of small follicles and ovary weight were significantly increased by supplementation of 12 g kg(-1) feed additive. Overall, dietary supplementation of polyherbal additive increased egg weigh, improved ovary characteristics and declined yolk trimethylamine level.
