Purpose: Renal epithelial cell injury by reactive oxygen species is a prerequisite step in the pathogenesis of urolithiasis, and there is increasing evidence that reactive oxygen species is produced and oxidative stress (OS) is developed during idiopathic calcium oxalate nephrolithiasis. It appears that the administration of natural antioxidants has been used to protect against nephrolithiasis in human and experimental animals.
Methods: Calcium oxalate urolithiasis was induced experimentally by administration of 0.
The association between serum gonadal steroids and urolithiasis in males received only limited attention. Calcium oxalate urolithiasis is induced by administration of ethylene glycol in drinking water. It appears that the administration of natural antioxidants has been used to protect against nephrolithiasis in human and experimental animals.

We evaluated the effect of sensory (direct current, 600 microamperes) and motor (monophasic pulse current, 2.5 to 3 milliamperes, 300-microsecond pulse duration, 100 Hz) intensities of cathodal current on the release of fibroblastic growth factor-2 (FGF-2) at the wound site and also the biomechanical and histological properties of healed skin.

Oxygen pre-exposure as a mild oxidative stress may enhance some endogenous defense mechanisms, so its effect on cisplatin-induced acute renal failure was investigated in present study. Twenty-four rats were divided into four groups.

In the present study, we investigated whether oxygen pretreatment induces delayed renal protection in rats. The possible role of some renal antioxidant agents was also investigated.

Female pregnant rats were orally treated with 0.1 mg/ml of morphine solution on the 21st day of gestation.

The objective of this study was to consider the effectiveness of consumption of iron fortified ready-to-eat cereal and pumpkin seed kernels as two sources of dietary iron on status of iron nutrition and response of hematological characteristics of women at reproductive ages. Eight healthy female, single or non pregnant subjects, aged 20-37 y consumed 30 g of iron fortified ready-to-eat cereal (providing 7.

The purpose of this study was to investigate the effects of pre-exposure to hyperoxic environment on rat renal IR injury for the first time.
Materials And Methods: The effects of 1 h/d pretreatment with oxygen (>or=95%) for 5 days on a right nephrectomized rat model of renal IR injury was investigated by comparing creatinine clearance, fractional excretion of sodium, plasma creatinine, blood urea nitrogen, and histological injury scores among three groups: IR (40 min ischemia-24 h reperfusion), sham (no IR), and hyperoxia (5 days intermittent pretreatment with oxygen + IR).
Objective: The objective of this study was to consider the effects of boron (B) and calcium (Ca) supplementation on mechanical properties of bone tissues and mineral content of the selected bones in rats.
Methods: Adult male Sprague Dawley rats underwent three different treatments with boron and calcium in their drinking water, while taking diet ad libitum for 4 weeks. Rats in the three treatment groups received 2 mg B/d, 300 mg Ca/d, and a combination of 2 mg B+ 300 mg Ca/d, respectively.
