Nitric oxide (NO), an important messenger molecule with widespread actions, is synthesized by NO synthases (NOS). In this study, we investigated the correlation between fiber type and NOS activity among ventilatory and limb muscles of various species. We also assessed the presence of the three NOS isoforms in normal skeletal muscles and how various NOS(More)
The goal of this study was to evaluate the importance of the inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-induced diaphragmatic contractile dysfunction. Many investigators have proposed that iNOS induction in the ventilatory and limb muscles of animals injected with Escherichia coli LPS leads to impaired muscle contractility and(More)
BACKGROUND The Peganum harmala is currently used by the Jordanian populations systemically for its antispasmodic, diuretic, sedative and analgesic effects and externally for its antirheumatic effect. OBJECTIVE To study effects of Peganum harmala on the reproductive system and fertility using adult male albino rats. MATERIAL & METHOD A total of 20 rats(More)
Neurons in the cuneate nucleus of the camel brain stem were studied by Golgi method. Six types of neurons were identified based on soma size and shape, density of dendritic trees, morphology and distribution of spines, and appendages. Type I neurons had large spherical somata with somatic appendages. Dendritic appendages were predominant on proximal(More)
Conventional electron microscopy of human cerebellar cortex has revealed two types of Purkinje neurons with different staining intensities. The light-stained type constitute the major type and both types have similar diameters. This finding was not reported in human before but in lower mammalian. Whether the different staining pattern of Purkinje neurons(More)
The morphological and quantitative features of neurons in the adult human ventral anterior thalamic nucleus were studied in Golgi preparations. Two neuronal types were found and their quantitative features were studied. Golgi-type I neurons were medium to large cells with dense dendritic trees and dendritic protrusions and short hair-like appendages. They(More)
