Zebra blenny protein hydrolysates as a source of bioactive peptides with prevention effect against oxidative dysfunctions and DNA damage in heart tissues of rats fed a cholesterol-rich diet.

High-cholesterol diet (HCD) is suspected to produce in excess free radicals having adverse effects on human health and causing atherosclerosis damage in heart tissues. In our study, the effects of zebra blenny protein hydrolysates (ZBPHs) were investigated on cardiac oxidant/antioxidant status as well as DNA damage and histopathological disorders in rats, fed with a hypercholesterolemic diet. The molecular weight distribution of the hydrolysates was determined by size exclusion chromatography, which analyzed a representative hydrolysate type with a weight range of 3-20kDa.

Antioxidant and hemolytic activities, and effects in rat cutaneous wound healing of a novel polysaccharide from fenugreek (Trigonella foenum-graecum) seeds.

The aim of this work was to evaluate the antioxidant and hemolytic activities as well as the in vivo wound healing performance of a novel polysaccharide (FWEP) extracted from fenugreek (Trigonella foenum-graecum) seeds. The antioxidant activity was evaluated in vivo and in vitro using various assays. Results showed that FWEP exhibited strong antioxidant activities but no hemolytic activity was observed towards bovine erythrocytes.
