Abstract/OtherAbstract:
An attempt was made to determine if the tissue response to surgical trauma and foreign body stimulus (silicone implants) could be altered using vitamin E in rats. The animals were divided into four groups: Group A served as controls, Group B were treated by intramuscular vitamin E, Group C were treated topically with vitamin E around the prosthesis, and Group D were treated topically with croton oil around the prosthesis. The animals in each group were killed at 2 week, 1 month, and 3 months intervals. The intraprosthetic pressure in each prosthesis was recorded using a strain gauge transducer. The capsules were then removed and examined histologically using a light microscope and the thickness of pseudocapsules was measured with an ocular micrometer. In Group B significantly thinner pseudocapsules were observed at 2 weeks, but there was no comparable difference either in thickness or degree of contracture (as measured by intraprosthetic pressures) between Groups A and B at 2 months and 3 months. In Group C, the pseudocapsules were significantly thicker at all tested periods and showed noticeable contracture at 3 months. In group D the pseudocapsules were thickest and cellular infiltrate more marked than in the other groups.
