The aim of this study was to evaluate the radioprotector effect of sodium selenite on the ultrastructure of submandibular glands in rats. Fifty-seven male albino Wistar rats were randomized to 4 groups: control, irradiated, sodium selenite and irradiated/sodium selenite. The animals in the sodium selenite and irradiated/sodium selenite groups received intraperitoneal injections of sodium seleni...

The present study was designed to examine the effects of lead nitrate (LN) and whether selenium has a cardioprotective effect on diabetic and non-diabetic rats. Selenium and LN were administered orally for 28 days to streptozotocin-induced diabetic and non-diabetic rats. Animals were divided into 8 groups: control, sodium selenite, LN, LN+Sodium selenite, diabetic-control, diabetic sodium selen...

Sodium selenite (1 mg/kg body weight, ip) for 10 consecutive days treatment showed marked increase in intra-erythrocytes K+ and plasma Na+ level while slight increase in Na+ K+ ATPase level. No mortality was observed at this dose of sodium selenite. However, sodium selenite pretreatment partially restored the Na+ K+ ATPase and intra-erythorcytes and plasma sodium level, while completely restore...

Ischemia/reperfusion injury (IRI) has lzong been an area of concern and focus of investigations. Erythropoietin (EPO) exhibits multiple protective effects, and selenium is an antioxidant trace element in the body, however, there have been no reports concerning the effects of EPO combined with sodium selenite on IRI. In the present study, a mouse model of renal IRI (RIRI) was pre‑treated with EP...

Thioacetamide is an organosulfur compound and reasonably anticipated to be a human carcinogenic and toxic effect. Sodium selenite is considered to be an anticarcinogenic and antioxidant, therefore, the aim of study is to evaluate the toxic effect of thioacetamide and the role of sodium selenite on renal tissues by using rat model. 24 Albino wistar rats of male sex (b.w: 200±30gm) were divided i...

the present investigation was performed to determine the effect of long-term administration of sodium selenite on the biochemical indices and concentration of thyroid hormones in calves. sodium selenite solution was drenched at 0.1 and 0.25 mg per kg body weight for 12 weeks. higher dose produced characteristic symptoms of selenosis whereas mild symptoms were observed with lower dose. the toxic...

The relative effectiveness of either sodium selenite or selenomethionine in the inhibition of mammary carcinogenesis was studied in virgin female Sprague-Dawley rats. In one experiment, rats were given 50 mg of 1-methyl-1-nitrosourea per kg of body weight s.c. at 50 days of age. Beginning 7 days post-1-methyl-1-nitrosourea, they were assigned to a basal diet containing 0.1 ppm of selenium or ba...

echium amoenum is an iranian indigenous medicinal plant. in this research the effect of hydroalchoholic extract of this plant on sodium-selenite induced cataract formation was evaluated. fifty five white rat pups were selected and divided into six groups. in first group (control 1) no elements injected. second group (control 2) was received normal saline on 11-18 postpartum. hydroalchoholic ext...
