introduction: high environmental temperature during summer months which leading to heat stress, is of great concern in all types of poultry production. feed consumption, growth rate, hatchability, mortality, and other important traits governing the prosperity of the industry are adversely affected by severe heat stress. literature suggests that the advantages of dietary l-carnitine and ascorbic...

Background Asthma is the most common chronic airway disease in children. We aimed to investigate the effect of vitamin C supplementation on improving the asthma symptoms in children. Materials and Methods: In a double-blind clinical trial: sixty 2-12-year-old children hospitalized with the diagnosis of asthma attack in the Ghaem an...

Background: Radioprotective effect of famotidine was previously shown on radiation induced micronuclei and chromosomal aberrations in human peripheral lymphocytes and mouse bone marrow cells however, its radioprotective property has never been studied in mouse spermatogenesis. It was also shown that vitamin C as an antioxidant also exert its radioprotective effect on many biological s...

objective oxygen intoxication plays an important role in the pathogenesis of some fetal diseases such as encephalopathy, ischemia& hypoxia. antioxidants can reduce oxidative damage in newborns. the object of this research was measuring total value of antioxidant and vitamin c in blood sample of pregnant women before delivery, and also in umbilical cord blood of their newborn, and repeating thes...

vitamin c, an antioxidant substance soluble in water, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various protein which has effect on structure and biochemical activity of them, the inhibition of this process seems very vital. for several years researches in this field have done their best to recognize the antidiabetics compounds. the aim of t...

Background: This study was conducted to investigate whether vitamin C can protect against plasma biochemical changes induced by lead poisoning in Cyprinus carpio. Methods: Three groups of common carp (n=30/group) were used in this study. Group 1 served as control, Group 2 was exposed to lead acetate (5 mg/L) for 15 days, and Group 3 received vitamin C (500 mg/kg) during the same duration of ...

The genotoxic effect of endosulfan and the modulatory effect of vitamin C in growing albino rats were studied by bone marrow micronucleus assay. Seven days old male Wistar rats were treated with 3, 6, 9, 12mg/kg Endosulfan orally (10 pups/group),for up to 60 days, at intervals of 24h. For 2 more groups (n=10/group), Endosulfan 9mg/kg and 12mg/kg was administered along with vitamin C (20mg/kg). ...

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...
