PTPRC and gonorrhea: There was a tendency towards negative correlation between MVD and percentage of tissue occupied by an overall leucocyte infiltrate (diffuse and clustered) assessed according to CD45 immune reactivity in PAC (M=8.6, Mdn=7.5, Rng=0–30, s.e.m.=1) (r=−0.338, P=0.06), whereas in peri-PAC, a tendency towards positive correlation between MVD and an overall leucocyte infiltrate (M=2.9, Mdn=2, Rng=0–10, s.e.m.=0.58) was detected (r=0.304, P=0.085) (Table 1).
