Enzymatic and non-enzymatic antioxidants in selected Piper species.
Piper species, commonly used in diet and traditional medicine were assessed for their antioxidant potential. Catalase activity was predominated in Piper longum, followed by Piper cubeba, green pepper, Piper brachystachyum and Piper nigrum. P. nigrum was richest in glutathione peroxidase and glucose-6-phosphate dehydrogenase, green pepper was richest in peroxidase and vitamin C while vitamin E w...

متن کاملEffects of Dystocia on Lipid Peroxidation and Enzymatic and Non-enzymatic Antioxidants in Crossbred Dairy Cows
The aim of the study was to evaluate oxidative stress in cows undergoing normal parturition and cows suffering from dystocia. The erythrocytic glutathione peroxidase (GSH-Px) activity, plasma vitamin A and ß-carotene concentrations, and paraoxonase PON1 activity were lowered (P<0.001, P<0.01, 0.05, and 0.05, respectively) in cows with dystocia compared to normal calving cows. The erythrocytic m...

background: in patients with non-obstructive azoospermia (noa), vital spermatozoa from the tissue is obtained from testes by enzymatic treatment besides the mechanical treatment. objective: to increase the sperm recovery success of testicular sperm extraction (tese), with enzymatic digestion if no sperm is obtained from testis tissue by mechanical method. materials and methods: tissue samples w...
متن کاملEffect of Non-enzymatic Antioxidants in Extender on Post-thaw Quality of Buffalo (bubalus Bubalis) Bull Spermatozoa
The objective of the present study was to determine the effect of non-enzymatic antioxidants (vitamin C or E) in tris-citric acid buffer (TCA) on post-thaw quality of buffalo (Bubalus bubalis) bull spermatozoa. Split pooled buffalo bull ejaculates were diluted in TCA egg yolk glycerol extender containing either vitamin C (TCAC), vitamin E (TCAE) or without antioxidant (TCAN) at 37°C. Extended s...
