Inflammatory Response of Channel Catfish to Abdominal Implants: A Histological and Ultrastructural Study

“…The basic structure of the fibrous capsule in channel catfish closely resembled fibrous capsules described after surgical implants in mammals (e.g., Williams and Roaf 1973;Hernandez-Jauregui et al 1974). The tissue lymphocytes and capillary neutrophils described here resembled those described previously from the peripheral circulation of channel catfish (Cannon et al 1980;Breazile et al 1982), except that those examined in our study lacked pseudopodia.…”

“…In mammals, large implants are commonly ensheathed in a fibrous capsule (Hench and Etbridge 1982). These capsules have been described histologically (e.g., Agnew et al 1962) and ultrastructurally (e.g., Hernandez-Jauregui et al 1974), but quantification of this foreign-body, inflammatory reaction has been incomplete, making comparison of different studies difficult (Coleman et al 1974). Early attempts to quantify tissue reactions to implants involved combinations of scores based on the estimated number of cells per high-power field, the amount of edema and necrosis evident, the number of capillaries, and the thickness of the tissue (Sewell et al 1955;Myers et al 1961).…”

Flexor tendon repair in children with zone 2 injuries: an innovative technique using autogenous vein

“…In the past, for zone l and zone 2 injuries, most surgeons removed a portion of the flexor tendon sheath around the repaired site in the fingers and thumb before the repair [1]. They believed this would allow better movement of the repaired tendon without interfering with the sheath and pulley system.…”

“…Removing some portion of the tendon sheath in zone 1 and 2 flexor tendon repair has been routinely performed [1]. Theoretically, it was believed that would prevent adhesions from developing between the tendon and its covering sheath and thus allow unrestricted motion of the repaired tendon without any interference of the sheath or pulley systems.…”
