Protein Carbonyl, Lipid Peroxidation, Glutathione and Enzymatic Antioxidant Status in Male Wistar Brain Sub-regions After Dietary Copper Deficiency.

Copper a quintessential transitional metal is required for development and function of normal brain and its deficiency has been associated with impairments in brain function. The present study investigates the effects of dietary copper deficiency on brain sub-regions of male Wistar rats for 2-, 4- and 6-week. Pre-pubertal rats were divided into four groups: negative control (NC), copper control (CC), pairfed (PF) and copper deficient (CD).

Morphological changes in spleen after dietary zinc deficiency and supplementation in Wistar rats.

Background: Study was conducted to determine the effect of dietary zinc deficiency and supplementation on the spleen morphology.

Methods: Pre-pubertal Wistar rats (40-50 g) were divided into two groups with 6 sub-groups each viz. zinc control (ZC, 100 μg/g zinc diet), pair fed (PF, 100 μg/g zinc diet), zinc deficient (ZD, <1 μg/g zinc diet, zinc supplementation control (ZCS), zinc supplementation pair-fed (PFS) and zinc supplementation deficient (ZDS, 100 μg/g zinc control diet).

Tracing of Zinc Nanocrystals in the Anterior Pituitary of Zinc-Deficient Wistar Rats.

The aim of this study was to trace zinc nanocrystals in the anterior pituitary of zinc-deficient Wistar rats by using autometallographic technique. Male Wistar rats (30-40 days of age, pre-pubertal period) of 40-50 g body weight were divided into the following: the ZC (zinc control) group-fed with 100 ppm zinc in diet, the ZD (zinc-deficient) group-fed with zinc-deficient (1.00 ppm) diet and the PF (pair-fed) group-received 100 ppm zinc in diet.

Dose-dependent short-term study of di-n-butyl phthalate on the testicular antioxidant system of Wistar rats.

Di-n-butyl phthalate (DBP), a xenobiotic, is widely used in industries as a softener for polyvinyl chloride resins. The aim of the present study was to evaluate whether DBP induces oxidative stress in testes of Wistar rats. DBP at doses of 500, 1,000 and 1,500 mg/kg b.

Dietary zinc deficiency effects dorso-lateral and ventral prostate of Wistar rats: histological, biochemical and trace element study.

Zinc deficiency has become a global problem affecting the developed and developing countries due to inhibitors in the diet which prevents its absorption or due to a very low concentration of bioavailable zinc in the diet. Being present in high concentration in the prostate and having diverse biological function, we investigated the effects of dietary zinc deficiency for 2 and 4 weeks on dorso-lateral and ventral prostate. Sixty prepubertal rats were divided into three groups: zinc control (ZC), pair fed (PF) and zinc deficient (ZD) and fed on 100 μg/g (zinc control and pair fed groups) and 1 μg/g (zinc deficient) diet.

Embryotoxic and teratogenic effects of nickel in Swiss albino mice during organogenetic period.

The present study evaluates potential hazardous of nickel (Ni(+2) as NiCl2 ·6H2O) to Swiss albino mice fetus. Ni was administered orally on body weight base from days 6 to 13 of gestation period. Based on LD50, Ni doses (46.

Protein carbonyl, 3β-, and 17β-hydroxysteroid dehydrogenases in testes and serum FSH, LH, and testosterone levels in zinc deficient Wistar rats.

The present study evaluated protein oxidation, alteration in hydroxysteroid dehydrogenases (3β- and 17β HSD) in testes and serum hormonal profiles of dietary zinc deficient Wistar rats. Pre-pubertal rats were divided into three groups: zinc control (ZC), pairfed (PF), and zinc deficient (ZD) and fed 100 ppm (ZC and PF groups) and 1.0 ppm (ZD group) zinc diet for 2- and 4-weeks.

Testicular apoptosis after dietary zinc deficiency: ultrastructural and TUNEL studies.

The present study was conducted in Wistar rats to determine whether prepubertal dietary zinc deficiency causes apoptotic changes in testes. Prepubertal male Wistar rats (40-50 gm) were divided into 3 groups: zinc control (ZC), pairfed (PF), and zinc deficient (ZD). Control and pairfed groups were given a 100 ppm zinc diet while the deficient groups received 1 ppm zinc diet for 2 and 4 weeks (w), respectively.

Effect of dietary zinc deficiency on testes of Wistar rats: Morphometric and cell quantification studies.

The present study investigates the effect of dietary zinc deficiency on testes of Wistar rats. Pre-pubertal rats (40-50g) were divided into three groups of 10 each viz. zinc control (ZC) and pair fed (PF) [100ppm zinc diet] and zinc deficient (ZD) [1ppm zinc diet].

Effect on histological and sperm kinetics in DBP exposed Wistar rats.

Di-n-butyl phthalate (DBP) is a ubiquitous environmental pollutant, extensively used as a softener for polyvinyl chloride resins. A study was conducted to evaluate its effect on reproductive function of Wistar rats. DBP was given orally at a dose of 500, 1000 and 1500 mg kg(-1) body weight for 7 days.

Metallothionein in male reproductive organs of adrenalectomized and hydrocortisone-treated Wistar rats.

Adrenalectomy resulted in an increase in metallothionein (MT) levels in testes, caput and cauda epididymis and prostate of rats but not in seminal vesicles where its levels decreased significantly. Inspite of administration of hydrocortisone, MT in testes, prostate (1.2 mg), caput (0.

Effect of adrenalectomy on rat epididymidis.

Aim: To investigate the effect of adrenalectomy (ADX) on the epididymidis of Sprague-Dawley rats.

Methods: The histological, biochemical (cholesterol protein, zinc, copper, alkaline and acid phosphatase aryl sulphatase, lactic dehydrogenase and leucine amino peptidase) and hormonal (FSH, LH and testosterone) changes of caput and cauda epididymis in ADX rats were observed.

Results: Organ wet weight, histological studies and morphometric measurements indicated a cellular degeneration in caput and cauda epididymis of ADX rats.
