Murine autoimmune oophoritis, epididymoorchitis, and gastritis induced by day 3 thymectomy. Immunopathology. (25/40)

(C57BL/6 X A/J) F1, (SWR/J X A/J) F1 and BALB/cBy mice, thymectomized on Day 3 (D3TX) or Day 7 (D7TX) or sham thymectomized (STX), were studied for immunopathologic changes in the ovary, testis, and gastric wall. In 95% of B6AF1, 100% of SWRAF1, and 35% of BALB/cBy mice ovarian disease developed, with onset at 5-6 weeks of age. Ovarian disease was not found in D7TX or STX mice. In D3TX mice, it was associated with mononuclear infiltration and ovarian follicle destruction, leading to atrophy. Epididymovasitis was detected in 70-90% of SWRAF1, 50% of B6AF1, and 64% of BALB/cBy mice after D3TX; whereas orchitis occurred in about 20% of SWRAF1 and B6AF1 mice. In some mice epididymovasitis also developed after D7TX, but not after STX. In contrast to the negative immunohistochemical findings in diseased ovaries, typical immune complex-like deposits of mouse IgG were detected by immunofluorescence along the basement membrane of epididymal ducts and seminiferous tubules. However, maximum incidence of epididymitis preceded immune complex detection. Gastritis developed in both female (57%) and male (50%) BALB/cBy mice after D3TX, occasionally after D7TX, but not after STX. Gastric mucosa was hypertrophic with dilated glands and heavy lymphocytic infiltrations throughout all gastric layers. BALB/cBy mice with gastritis usually did not have disease in the gonads, and vice versa. This study, therefore, confirms and extends the findings of Nishizuka and colleagues.  (+info)

Bilateral salmonella salpingo-oophoritis. (26/40)

A previously healthy nulliparous caucasian female presented with lower abdominal pain and a history of diarrhoea and vomiting for 2 weeks. Repeated stool examinations and blood culture were negative. A lump in the lower abdomen became more apparent over the next 2 weeks and a subsequent laparotomy revealed bilateral tubo-ovarian abscess formation. One ovary which was endometriotic and both the tubes were excised and the pus yielded a heavy growth of Salmonella stanley.  (+info)

Organ-specific autoimmune diseases induced in mice by elimination of T cell subset. I. Evidence for the active participation of T cells in natural self-tolerance; deficit of a T cell subset as a possible cause of autoimmune disease. (27/40)

Organ-specific autoimmune diseases such as oophoritis, gastritis, thyroiditis, and orchitis were induced in female or male nude (nu/nu) mice by the transfer of nu/+spleen cells from which particular Lyt T cell subset(s) had been removed: nu/+spleen cells treated with anti-Lyt-1 plus complement (C) caused disease in recipient nude mice; anti-Lyt-2 plus C-treated spleen cells, in contrast, did not. The cells responsible for disease induction are believed to be Thy-1+, Lyt-1-, 2,3- (Thy-1, Lyt-1, 2,3), since spleen cells treated with mixed antisera, including anti-Lyt-1 and anti-Lyt-2, plus C, could induce the disease with almost the same incidence as anti-Lyt-1 plus C-treated cells (oophoritis 50%, gastritis 25%, thyroiditis 10-20%, and orchitis 40%). Cells treated with mixed antisera of anti-Thy-1, anti-Lyt-1, and anti-Lyt-2, plus C, could not induce autoimmune disease. Each induced autoimmune disease could be adoptively transferred to other nude mice via spleen cells, with resulting histological lesion of corresponding organs and development of specific circulating autoantibodies. Since anti-Thy-1 plus C treatment of donor spleen cells abrogated the capacity to transfer the disease, we conclude that T cells are required as effector cells, and that these may develop from Lyt-1-, 2,3- cells. Lyt-1+, 2,3- cells were demonstrated to have suppressive activity upon the development of the diseases; induction of autoimmunity was completely inhibited by the cotransfer of Lyt-1+, 2,3- cells with Lyt-1-, 2,3- cells. When anti-Lyt-2 plus C-treated cells (i.e., Lyt-1+, 2,3- and Lyt-1-, 2,3- cells) were mixed with anti-Lyt-1 and anti-Lyt-2 plus C-treated cells (i.e., Lyt-1-, 2,3- cells) in various ratios, then transferred to nude mice, the development of each autoimmune disease was clearly inhibited, even by small doses of Lyt-1+, 2,3- cells. The autoimmune disease we were able to induce was quite similar to human organ-specific autoimmune disease in terms of the spectrum of organs involved, histopathological features, and the development of autoantibodies to corresponding organ components (oocytes, parietal cells, thyroid colloid, including thyroglobulin, and sperm).(ABSTRACT TRUNCATED AT 400 WORDS)  (+info)

Some operative and postoperative hazards of legal termination of pregnancy. (28/40)

Analysis of 1,317 patients admitted for N.H.S. abortion showed an overall morbidity of 16.8% excluding urinary tract infection. Genital infection, chest infection, reevacuation or perforation of the uterus, and haemorrhage were the more common complications. There was one maternal death.  (+info)

Autoimmune oophoritis in thymectomized mice: T cell requirement in adoptive cell transfer. (30/40)

Experimental autoimmune oophoritis characterized by rapid loss of oocytes with infiltration of lymphocytes and circulating anti-oocyte antibodies could be induced in (C57Bl/6Cr x A/JCr)F1 mice after thymectomy (Tx) at a critical age of 3 days (Tx-3) but not 0. or 7 days after birth without any sensitization. The lesion of the ovary was passively transferred into neonatal, but not adult, mice 7 days after intraperitoneal (i.p.) injection of spleen cells (10(7)) obtained from syngeneic donors with oophoritis. In contrast, the lesion was never evoked in the recipient ovaries when spleen cells were prepared from Tx-3 mice ovariectomized at day 0. The spleen cells prepared from Tx-3 donors, depleted of T cells by incubation with anti-Thy 1.2 antiserum plus guinea-pig complement (GPC), showed no transfer capacity. However, the spleen cells prepared from the same donors, depleted of B cells with anti-Ig antiserum plus GPC, still kept the capacity to induce oophoritis. The results indicate the presence of autoreactive T cells against ovarian tissues in Tx-3 mice which are capable of inducing oophoritis.  (+info)

Study on cellular events in postthymectomy autoimmune oophoritis in mice. I. Requirement of Lyt-1 effector cells for oocytes damage after adoptive transfer. (31/40)

Neonatal thymectomy during the critical period, 2-4 d after birth, can induce various organ-specific autoimmune diseases including oophoritis in A/J mice. The oophoritis thus induced was passively transferred into neonatal mice by injection of spleen cells obtained from syngeneic donors with the disease. Recipient ovaries were rapidly damaged with remarkable mononuclear cell infiltration and destruction of follicular structures. The phenotype of effector cells responsible for successful adoptive transfer was found to be Thy-1+, Lyt-1+,23-, Ia-, Qa-1-, and was sensitive to antithymocyte serum treatment but resistant to cyclophosphamide treatment or in vitro X-ray irradiation. The compatibility between donor and recipient at the major histocompatibility complex was not required for the effector phase of transfer. The oophoritis induced in BALB/c (nu/+ or +/+) was also shown to be transferred into athymic BALB/c nude mice with resulting ovarian lesion and circulating autoantibodies against oocytes. In this transfer system, the effector cells were also demonstrated to be T cells with the Lyt-1+,23- phenotype. Adoptive transfer experiments in both systems revealed that the destruction of ovaries in postthymectomy autoimmune oophoritis was mediated by Lyt-1 T cells. Whether these T cells can be distinguished from other Lyt-1 cells, such as T helper cells and effector T cells in delayed-type hypersensitivity (DTH), is not clear at present, but the results suggest that the effector mechanisms may be closely related to a DTH reaction.  (+info)

Study on cellular events in post-thymectomy autoimmune oophoritis in mice. II. Requirement of Lyt-1 cells in normal female mice for the prevention of oophoritis. (32/40)

Autoimmune oophoritis that develops in A/J mice after neonatally thymectomy (NTx) was prevented by a single intraperitoneal injection of spleen cells or thymocytes from normal adult female mice. Prevention of oophoritis was achieved when spleen cells were given within 2 wk after Tx. When spleen cells were obtained from neonatally oophorectomized mice, four times more cells were required for the prevention of oophoritis, but those from the mice oophorectomized on day 7 after birth had equivalent capacity to prevent oophoritis to those from normal female mice. The spleen cells from normal A/J mice that prevented the development of oophoritis in NTx A/J mice were Thy-1+, Lyt-1+,23-, Ia-, Qa-1-, sensitive to in vitro irradiation with 400 rad, resistant to administration of cyclophosphamide or anti-thymocyte serum, and were not eliminated by adult thymectomy. Thymocytes with oophoritis-preventing capacity were also found to be Lyt-1+,23- and TL-1,2,3-. These results seem to correlate well with the finding that the Lyt-1 subpopulation is substantially decreased in NTx mice. The results suggest that, in this post-thymectomy autoimmune oophoritis, NTx abrogates the Lyt-1 T cell subpopulation that serves as suppressive or regulatory cells over developing self-reactive cells directed toward ovarian antigens, and eventually may cause autoimmune oophoritis.  (+info)
