  • Title: [Testing tissue reactivity to surgical sutures using a personal point method].
    Author: Staniszewska-Kuś J, Rutowski R, Paluch D.
    Journal: Polim Med; 1997; 27(1-2):3-15. PubMed ID: 9380600.
    Abstract:
    In the Institution of Experimental and Biomaterial Research Surgery of Medical Academy in Wrocław works on biological methods of estimation of different biomaterials including, first of all, surgical threads have been carried out for 30 years. The purpose of this work is to define the local biological reaction on the implanted absorptive and non-absorptive surgical threads. The present estimation of reactivity of surgical threads depended on a description of a great number of histological samples and on observation of numerous microscopic fields for each tested thread. It required long and tiring descriptions the analysis of which was made difficult and often led to non-objective conclusions. The presented punctual system depends on observation of the field of vision in a biological microscope which includes transverse cross-section of the implanted thread together with the surrounding tissues. The estimation of the histological samples in magnification of 45 times allows to define the range of infiltration of tissues with inflammatory cells in comparison with the diameter of the implanted thread. Observations in magnification 120 times allow to differentiate cells included in non-specific inflammatory process. The worked put punctual system enables to define the level of tissue reaction on the basis of uniform criteria.
