Site Map Recent studies indicate that the cellular receptors for CV (CD13) exist predominantly in mononuclear cells, venular endothelial cells, epithelial cells in the respiratory tract and renal tubules, fibroblasts, brush‐border cells of the intestine, stromal cells in the bone marrow, and the synaptic membrane of the central nervous system. The lungs, immune organs, and systemic small vessels are the main targets of virus attack, so that extensive consolidation of the lung, diffuse alveolar damage with hyaline membrane formation, respiratory distress, and decreased immune function are the main causes of death. Red degeneration (necrobiosis) is a form of degeneration that occurs characteristically but not exclusively in pregnancy, and the process is Contact | In conclusion, we consider that SARS is a viral disease that can result in injury to multiple organs, although the predominant pathology involves the lungs.
