In cultured vascular smooth muscle cells, the baseline mRNA and protein levels of an inducible type of nitric oxide synthase were barely detectable. Interferon gamma, tumor necrosis factor-alpha, and interleukin-1 beta each markedly increased mRNA and protein levels of this enzyme in parallel with the production of nitrite, a stable oxidative metabolite of nitric oxide. Actinomycin D abolished ...

Aim: This study aimed to investigate the effects of relaxin (RLX) on hypertensive disorders pregnancy (HDP) and fetal growth restriction (FGR) using a nitric oxide synthase (NOS) inhibitor-induced HDP murine model.

Introduction: The relation between morphine and nitric oxide release has been shown. Due to important role of nitric oxide in regulation of skin blood flow, the aim of this study was to investigate the effect of nitric oxide synthase inhibitor (L-NAME) and nitric oxide synthesis precursor (L-arginine) on skin blood flow of intact and morphine-dependent rats. Methods: Skin blood flow of hind pa...

A transient ipsilateral retinotectal projection is normally eliminated during embryonic development of the chick visual system. Administration of the NMDA receptor antagonist 5-methyl-10, 11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine (MK-801) during the developmental period in which this projection normally disappears prevented its complete elimination. Previous studies showed that tectal ce...

The earliest recorded association of dietary salt with blood pressure was reported by Huang Ti Nei Ching Su Wein (ca. 1500 B.C.), who noted that “if large amounts of salt are taken, the pulse will stiffen or harden” (page 82).1 In 1904, Ambard and Beaujard first demonstrated rigorously that dietary salt can increase blood pressure in normal volunteers.2 Throughout the 20th century, the relation...

background: the aim of this study was to compare the effects of diode laser irradiation on wound healing in oral rat mucosa and also to measure the amount of inducible nitric oxide synthase (inos) and endothelial nos (enos) on oral wound healing. healing was assessed by histology and the amounts of enos and inos were measured by real‑time polymerase chain reaction (pcr). materials and methods: ...

Objective(s):The neuropeptide calcitonin gene-related peptide (CGRP) has long been postulated to play an integral role in the pathophysiology of migraine. Earlier studies showed that CGRP can stimulate the synthesis and release of nitric oxide (NO) and cytokines from trigeminal ganglion glial cells. The purpose of this study was to determine the effect of 17β-estradiol in regulation of CGRP exp...
