In vitro sensitivity of mouse esophagus to agonists in different pH medium values.

Aim: The aim of this study is to determine the in vitro sensitivity of mouse esophagus to contracting and relaxing agonists in different pH medium values.

Materials And Methods: Forty-eight Swiss albino mice (30-40 g) of both sexes were anesthetized with tiopental sodium (30 mg/kg). After exsanguinations from abdominal artery, esophagi were removed and suspended under 0.

Pentylenetetrazol-induced seizures are not altered by pre- or post-drug exposure to a 50 Hz magnetic field.

Purpose: To investigate whether pre- and post-drug magnetic field (MF) exposure of 50 Hz, 0.2 mT has any significant effect on pentylenetetrazol (PTZ)-induced seizures in mice.

Material And Methods: MF was generated by a pair of Helmholtz coils.

Effect of glycerol on endothelium-derived factors in the vasculature of the rabbit kidney.

1. In the present study, endothelium-derived relaxing factor (EDRF/nitric oxide (NO)), conversion of big endothelin (ET)-1 to endothelin-1 (ET-1) and the role of reactive oxygen species were investigated in kidneys isolated from glycerol (GLY)-pretreated rabbits. 2.
