The Effect Of Nerve Growth Factor (Ngf) Incorporation Into Swine Intestinal Submucosa (Sis) Suture Material On The Healing Process In Gastrocnemius Muscle, Nicole K. Alexander

PCOM Biomedical Studies Student Scholarship

The repair of gastrocnemius muscle incisions were evaluated histologically in a rat model. Comparisons were made between carbon dioxide laser and scalpel incisions closed with sutures prepared from Swine Intestinal Submucosa (SIS) with and without added Nerve Growth Factor. This study was conducted in conjunction with two other studies, one comparing epidermal repair and the other comparing kinesthetic changes post-operatively in the same animal model. Thirty-five days post-surgery the animals were euthanized and an area of muscular tissue encompassing the operative site was excised and evaluated microscopically for the following: presence of macrophages, integrity of the muscle, leukocytes present within …
