Assessment of tissue responsiveness after implantation of a new block copolymer into rat tissue

The report describes tissue response an implantation of new block copolymer and compares with tissue response after presently used in medicine polymer implants. Implants shaped as 15 x 3 mm cylinders were placed subcutaneously on the abdomen and into muscles of both tight of Wistar rats. After 3, 7 and 14 days was taken tissue specimens with implants and kidneys to gross and light microscope examination. During the experiment there was not toxic signs considering rat's appearance and behaviour. Microscopic examination shows no difference between tissue response to presently in medicine used implants and new polymers.
