Histopathologic comparison of nontreated and LT-R antagonist-treated rat endometriosis. (a–b) Nontreated rat endometriosis at 4 days after, and enlargement of rectangular area. (Stain: H&E. Magnification: a: ×10 objective, ×10 ocular; b: ×4 objective, ×10 ocular.) (c–d) LT-R antagonist-treated rat endometriosis at 4 days after, and enlargement of rectangular area. (Stain: H&E. Magnification: c: ×10 objective, ×10 ocular; d: ×4 objective, ×10 ocular.) am = abdominal muscle; pc = peritoneal cavity; asterisk = transplanted uterine; arrowhead = basement membrane; at both ends of broad arrow = proliferative lesion area.

3. FIGURE 2
The comparison of mast cell count per light microscopic field for nontreated and LT-R antagonist-treated rat endometriosis. (Magnification: ×40 objective, ×10 ocular.) The bar graphs indicate the mean mast cell count, and error bars indicate ±1 SD. Statistical analysis was performed using the Mann-Whitney U test. ▩ = undegranulated mast cells count. ■ = degranulated mast cells count.

Light and electron microscopic observations of nontreated (a–d) and LT-R antagonist-treated (e–h) rat endometriosis. (a) Light microscopic observation at 4 days after uterine autotransplantation. (Stain: toluidine blue. Magnification: ×100 objective, ×10 ocular.) Infiltration of mast cells (M) and fibroblasts (F) is observed in the proliferative lesion area of peritoneum autotransplanted from the uterus. (b) Electron microscopic observation at 4 days after uterine autotransplantation. In the peritoneum autotransplanted from the uterus, proliferation of fibroblasts (F) can be seen, and thick collagen fibers (C) have formed around these cells. (Scale bar = 3 μm). (c) Light microscopic observation at 7 days after uterine autotransplantation. (Stain: toluidine blue. Magnification: ×100 objective, ×10 ocular.) Infiltration of mast cells (M) and fibroblasts (F) is observed in the proliferative lesion area of peritoneum autotransplanted from the uterus. (d) Electron microscopic observation at 7 days after uterine autotransplantation. In the peritoneum autotransplanted from the uterus, thick collagen fibers (C) are formed densely around some fibroblasts (F). (Scale bar = 3 μm.) (e) Light microscopic observation at 4 days after uterine autotransplantation. (Stain: toluidine blue. Magnification: ×100 objective, ×10 ocular.) Numerous apoptosis of proliferative fibroblasts (arrow) are observed in peritoneum autotransplanted from the uterus. Some apoptotic fibroblasts have come off the peritoneal tissue. (f) Electron microscopic observation at 4 days after uterine autotransplantation. The peritoneum autotransplanted from the uterus shows apoptosis of proliferative fibroblasts (F), which in turn show nuclear fragmentation (*). Collagen fibers are thin and have disappeared around these apoptotic fibroblasts. Arrow indicates “CSS,” a sign of apoptotic induction. (Scale bar = 5 μm.) (g) Light microscopic observation at 7 days after uterine autotransplantation (Stain: toluidine blue. Magnification: ×100 objective, ×10 ocular.) Some macrophages (m) and phagocytized apoptotic bodies (*) are observed in peritoneum autotransplanted from the uterus. (h) Electron microscopic observation at 7 days after uterine autotransplantation. The peritoneum autotransplanted from the uterus shows macrophage (m) phagocytizes and numerous apoptotic bodies (*). Collagen fibers are thin and have disappeared around the macrophage. (E = eosinophil. Scale bar = 3 μm.)
