to study the effects of postharvest treatments of spermidine and putrescine on storage quality of ‘hayward’ kiwifruit, the present research was performed. in november 2010, fruits were hand picked from fajr orchardist corporation in sari and transported to postharvest physiology laboratory. fruits were dipped for 4 minutes in either spermidine or putrescine solutions (0.5, 1.0 and 1.5 mm), and ...

the aim of this study was to investigate the effects of administering antioxidants, including vitamin c and chitosan on oxidative stress markers in muscle as edible tissues of cyprinus carpio exposed to cadmium chloride. in this experiment, by exposing to 0.2 mg/l cadmium chloride for 21 days, fish were fed a normal diet, diet containing chitosan (1000 mg/kg diet), vitamin c (1000 mg/kg diet) o...

background: cadmium (cd) intoxication can cause oxidative stress and involve the antioxi-dant defense system in hepatocytes. administration of vitamin c, chitosan, or a combination of both may prevent cd-induced oxidative damage. methods:cyprinus carpio were distributed into six groups. the control group received normal feed (group i). group ii was exposed to 0.2 mg.l-1 cadmium chloride. group ...

The vitamin D endocrine system, besides playing pivotal roles in calcium homeostasis & bone mineral metabolism, is now recognized to subserve a wide range of fundamental biological functions in cell differentiation, inhibition of cell growth as well as immuno modulation. Vitamin D is a prohormone which is converted into its active hormonal form 1, 25 (OH)D2 D, 1, 25 (OH)D2 D activates its cellu...

Recent studies suggest that vitamin D is related to allergic rhinitis (AR). In this review, we first discuss the physiology and metabolism of vitamin D, then we review the function of vitamin D in the immune system, and above all, we highlight the current research regarding the role of vitamin D in AR. Finally, we find that there are both experimental and clinical studies showing that vitamin D...

Rabbits are widely used as laboratory animals for experimental surgery. Anesthesia of rabbits may present complications unless the method is easy to apply and safe to use. In present study, effects of different dosages of vitamin C on thiopental sodium induced anesthesia in 25 male New Zealand white rabbits were studied. In the animals that had not received vitamin C treatment before thiopental...
