Department of Morphological Sciences (Histology), Faculty of Medicine, University of Córdoba, Spain.

Electron microscopic analysis was used to study the ultrastructural changes taking place in rat soleus muscle following intraperitoneal administration of pure heroin. Degenerative changes observed consisted primarily of hypercontracted fibers at different stages of development. Evidence of regeneration was also found. Results show the myotoxic effect of pure heroin on skeletal muscle. The pathogenesis of muscle damage is discussed.

UI MeSH Term Description Entries
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
