An ultrastructural study of blood vessels in peripheral nerves of leprosy patients: blood vessels in peripheral nerves.
Ultrathin sections of nerves of tuberculoid and lepromatous leprosy were examined in an electron microscope for changes in endoneural blood vessels. In the tuberculoid nerves, hypertrophy of endothelial cells was the most prominent feature. This was to such an extent that the lumen of blood vessel was often closed. Endoneural blood vessels showed multilayers separated by collagen and ground sub...
متن کاملRole of Local Nerves and Prostaglandins in Regulation of Basal Blood Flow and Hypercapnic Vasodilatation of Cerebral Blood Vessels in the Rabbit
The mechanisms underlying cerebral vasodilatation during hypercapnia are not fully understood. To examine the role of nerves and prostaglandins in the regulation of basal blood flow and in hypercapnia-induced vasodilatation in the cerebral blood vessels of rabbit.Cerebral blood flow was measured by laser Doppler flow-meter in 18 NZW rabbits anesthetized with sodium pentobarbital. Tetrodetoxin ...
متن کاملCryogenic damage to peripheral nerves and blood vessels in the rat.
The effects of cryogenic injury on femoral blood vessels and nerves were studied in 28 rats. The femoral neurovascular bundles were dissected out bilaterally and the vessels and nerves subjected to cryogenic injury. The rats were sacrificed at intervals of up to 2 weeks. Damage to the nerves and to a number of femoral vessels was severe and included necrosis and thrombus formation. The results ...
متن کاملThe Effects of Impact Vibration on Peripheral Blood Vessels and Nerves
Research regarding the risk of developing hand-arm vibration syndrome after exposure to impact vibration has produced conflicting results. This study used an established animal model of vibration-induced dysfunction to determine how exposure to impact vibration affects peripheral blood vessels and nerves. The tails of male rats were exposed to a single bout of impact vibration (15 min exposure,...
