Combined effects of melatonin and topical hypothermia on renal ischemia-reperfusion injury in rats

Acta cir. bras; 33 (3), 2018
Abstract Purpose: To evaluate whether their combination was more effective than either alone in decreasing renal damage due to ischemia/reperfusion (I/R) injury in rats. Methods: Thirty-two Wistar rats were assigned to four groups. Following right nephrectomy, their left kidneys were subjected to warm...

Antioxidant enzyme profile and lipid peroxidation products in semen samples of testicular germ cell tumor patients submitted to orchiectomy

Int. braz. j. urol; 43 (4), 2017
ABSTRACT Purpose To determine enzymatic antioxidant and lipid peroxidation levels in seminal plasma of patients orchiectomized for testicular tumors. Materials and Methods The study included 52 patients: 26 control men and 26 orchiectomized patients for testicular tumor, of which 12 men had seminoma ...

Induction of defense-related enzymes in patchouli inoculated with virulent Ralstonia solanacearum

Background: Defense-related anti-oxidative response is a vital defense mechanism of plants against pathogen invasion. Ralstonia solanacearum is an important phytopathogen. Bacterial wilt caused by R. solanacearum is the most destructive disease and causes severe losses in patchouli, an important aromatic...

Oxidative stress in carotid arteries of patients submitted to carotid endarterectomy. The role of aging process

Acta cir. bras; 31 (8), 2016
ABSTRACT PURPOSE: To evaluated the role of oxidative stress on aging process in patients submitted to carotid endarterectomy. METHODS: Twenty patients were divided into two groups: older group (≥ 70 years old); and the younger group (< 70 years old). We evaluated the reactive oxygen species ...

The beneficial effects of Montelukast against 2 3 7 8 tetrachlorodibenzo dioxin toxicity in female reproductive system in rats

Acta cir. bras; 31 (8), 2016
ABSTRACT PURPOSE: To determine the toxic effect of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on reproductive system and the beneficial effects of Montelukast (ML) with histological and biochemical analysis. METHODS: Rats were randomly divided into four equal groups (control, TCDD, ML and TCDD+ML). Ti...

The protective cardiac effects of Β-myrcene after global cerebral ischemia/reperfusion in C57BL/J6 mouse

Acta cir. bras; 31 (7), 2016
ABSTRACT PURPOSE: To investigate the protective effect of β-myrcene (MYR) on oxidative and histological damage in mice heart tissue caused global cerebral ischemia/reperfusion (IR) in C57BL/J6 mice. METHODS: Animals(n=40) were randomly divided into four groups: (1)control, (2)IR, (3)MYR and (4)MYR...

Effect of Otostegia persica extract on ischemia/reperfusion induced renal damage in diabetic rats. A biochemical study

Acta cir. bras; 31 (6), 2016
ABSTRACT PURPOSE: To evaluate the effect of Otostegia persica (O. persica) extract on renal damage induced by ischemia/reperfusion (I/R) in diabetic rats. METHODS: Forty-eight rats were subjected to right nephrectomy; then, they were allocated into six groups: Sham; Diabetic sham; I/R; Diabetic I/R; I/...

Protective effect of metformin on testicular ischemia/reperfusion injury in rats

Acta cir. bras; 31 (6), 2016
ABSTRACT PURPOSE: To investigate the protective effect of metformin on testicular ischemia/reperfusion (I/R) injury in rats. METHODS: Eighteen adult male Wistar rats were randomly divided into three experimental groups (n=6), as follows: Sham, I/R, and Metformin. 1-hour ischemia was induced by the left...

Cytotoxicity and hepatoprotective attributes of methanolic extract of Rumex vesicarius L

Biol. Res; 48 (), 2015
BACKGROUND: To evaluate the hepatoprotective potential and invitro cytotoxicity studies of whole plant methanol extract of Rumex vesicarius L. Methanol extract at a dose of 100 mg/kg bw and 200 mg/kg bw were assessed for its hepatoprotective potential against CCl4-induced hepatotoxicity by monitoring act...
