 AB    The distribution of leukocyte subtypes in the sheep ovary following
       laser drilling of the ovarian capsule was examined to understand a
       possible mechanism by which this treatment promotes ovulation in
       polycystic ovarian syndrome. Ovaries were removed from sheep at
       different time-points following laparoscopic laser drilling and
       immunohistochemical detection of leukocyte subtypes, using specific
       monoclonal antibodies; standard histological staining was performed.
       Migration of leukocytes into the laser-drilled site was observed as
       early as 6 h after laser drilling and the total number of leukocytes in
       the site was found to increase up to the 12th day after surgery. In the
       earlier period, polymorphonuclear leukocytes were the dominant leukocyte
       subtypes, while macrophages and lymphocytes were the major cellular
       components on the 12th day and later. These results show that the tissue
       changes in the ovary following laser drilling are consistent with a
       local inflammatory reaction. The prolonged appearance of numerous
       macrophages following the acute inflammatory phase could lead to the
       secretion of cytokines and other substances suggested to be important in
       promoting ovulation. These data indicate that part of the effectiveness
       of the laser drilling in polycystic ovarian syndrome may be attributable
       to the secretory products of these leukocytes.
