  • Thus PAF released from inflammatory phagocytes stimulates macrophage and neutrophil chemotaxis and oxidative metabolism viagra safe sites and nitric oxide generation. These include various proteases, lipases, matrix metal- Nonparenchymal Cells and Macrophages 225 loproteinases, plasminogen activator, acid phosphatase, and cathepsin D. These cells also express increased numbers of functionally active receptors for PAF , interestingly. E.

    In support of this possibility is the finding that administration of a PAF receptor antagonist reduces tissue injury induced by endotoxin. Upregulation of PAF receptors may represent an important mechanism underlying macrophage and endothelial cell activation following hepatotoxicant exposure. Hydrolytic Enzymes Macrophages and endothelial cells activated by inflammatory stimuli can also generate proteolytic and lysosomal enzymes. Liver macrophages and endothelial cells produce increased quantities of PAF , following exposure of animals to endotoxin.

    In the hypothalamus, both vasopressin and oxytocin viagra safe sites are synthesized primarily in two nuclei, the paraventricular nucleus and the supraoptic nucleus. Lateral to these neurons are the magnocellular neurons, which synthesize and release the two posterior lobe neurohormones, and a third neuron group that gives rise to a descending brain stem and spinal projection for regulating autonomic nervous system functions (see next section). There do not seem to be major differences in the numbers and locations of oxytocin-containing neurons in the nervous systems of males and females, although oxytocin is best known for its actions on female organs. Hence, other viagra safe sites important actions of this peptide will likely be discovered.

    As described earlier, there are parvocellular neurosecretory neurons in the portion of the nucleus that apposes the third ventricle. Experiments in animals have shown that the paraventricular nucleus comprises at least three distinct cell groups.
