Effects of cell phone radiation on lipid peroxidation, glutathione and nitric oxide levels in mouse brain during epileptic seizure.

The objective of the this study was to evaluate the effects of cellular phone radiation on oxidative stress parameters and oxide levels in mouse brain during pentylenetetrazole (PTZ) induced epileptic seizure. Eight weeks old mice were used in the study. Animals were distributed in the following groups: Group I: Control group treated with PTZ, Group II: 15min cellular phone radiation+PTZ treatment+30min cellular phone radiation, Group III: 30min cellular phone radiation+PTZ treatment+30min cellular phone radiation.

In vitro sensitivity of rat esophagus to agonists in different alkaline mediums.

Aim: An in vitro study was performed to determine the in vitro sensitivity of rat esophagi to contracting and relaxing agonists in different alkaline mediums.

Materials And Methods: Twenty-four Wistar rats weighing 200 to 250 g were included in the study. After inducing anesthesia with thiopental sodium (50 mg/kg), the rats were killed, and the distal esophagus (DE) and gastroesophageal junction (GEJ) were removed.

Effect of phototherapy on growth factor levels in neonatal rat skin.

Aim: Neonates undergoing surgery may receive phototherapy (PT) for the treatment of hyperbilirubinemia. Although the effects of PT on neonatal structures are well documented, the effect of PT on wound healing has not been previously evaluated. An experimental study was performed to evaluate the effect of PT on growth factor levels responsible for wound healing in neonatal rat skin.

Effect of phototherapy on gastrointestinal smooth muscle activity and oxidative stress.

Aim: To evaluate the effect of phototherapy on gastrointestinal smooth muscle activity and oxidative stress.

Methods: Wistar albino rats (n = 18, in the first 7 days of life) weighing 7 ± 2 g with both sexes were included in the study. The animals were randomized into three groups.

The effects of beta-blockers on endothelial nitric oxide synthase immunoreactivity in the rat corpus cavernosum.

Objectives: To explain the mechanism of the effects of beta-blockers on endothelial dysfunction and release of nitric oxide from the endothelium.

Methods: A total of 72 Sprague-Dawley rats were divided into 9 different groups as follows: group 1: control (n = 10), group 2: metoprolol (Beloc) 100 mg/kg/d (n = 7), group 3: carvedilol (Dilatrend) 50 mg/kg/d (n = 7), group 4: nebivolol (Vasoxen) 10 mg/kg/d (n = 6), group 5: estrogen receptor (ER) antagonist ICI 182.780 (Fluvestrant) 50 microg/g (n = 10), group 6: nebivolol+ER antagonist (n = 8), group 7: androgen receptor (AR) antagonist (flutamide) 20 mg/kg (n = 7), group 8: nebivolol+AR antagonist (n = 7), and group 9: DMSO (solvent for ER antagonist) (n = 10).

Effect of whole gut irrigation solutions on gastrointestinal smooth muscle activity.

Background/purpose: It has been suggested that whole gut irrigation (WGI), which is a preparation method for large bowel surgery or colonoscopy, increases gastrointestinal motility by creating a gastrocolic reflex. An experimental study was performed to evaluate the effect of different WGI solutions on gastrointestinal smooth muscle activity.

Materials And Methods: Thirty Wistar albino rats weighing 200 to 250 g were enrolled in the study.

Esophageal and gastric smooth muscle activity after carbon dioxide pneumoperitoneum.

Background: The metabolic changes associated with carbon dioxide (CO(2)) pneumoperitoneum include metabolic acidosis and lowered intra-abdominal pH values. An experimental study was performed to evaluate the effect of CO(2) pneumoperitoneum on esophageal and gastric smooth muscle sensitivity in response to several agonists.

Methods: Wistar albino rats, weighing 200-250 g, were allocated into three groups.
