“…In that examination we observed histopathological changes which in many cases became evident especially in the central part of the slices. Similar observations have been described also by other authors using comparable incubation conditions (Smith et al, 1985(Smith et al, , 1986Beamand et al, 1993;Miller et al, 1993;Gokhale et al, 1995;Olinga et al, 1997;Toutain et al, 1998;Hashemi et al, 1999;Evdokimova et al, 2001;Fisher et al, 2001). These histopathological changes are paralleled by a decline in the biochemical functions (Wright and Paine, 1992;Lake et al, 1993;Gokhale et al, 1997;Olinga et al, 1997;Kuhn et al, 1998;Müller et al, 1998;Lerche-Langrand and Toutain, 2000;Evdokimova et al, 2001;Gebhardt et al, 2003).…”
