    To describe the changes in reproductive hormone levels in the bottle-nosed dolphin Tursiops truncatus gilli, serum samples were obtained at 5-7 day intervals or biweekly from three sexually mature females kept in captivity wlthout adult males for period of 13 or 31 months from June 1982 through December 1984. Serum levels of estradiol, progesterone and LH were measured by radioimmunoassay (RIA). In spring through fall, 2 to 7 cyclic rises of progesterone, some of which were preceded by estradiol elevations, occurred at about one month intervals. No cyclic rise of progesterone was found in winter. A markedly elevated level of LH assumed to be a pre-ovulatory surge was detected. These changes in serum hormone levels were considered to represent sexual cycles with ovulations occurring spontaneously in the species. One female, however, showed prolonged luteal phase lasting about 5 months twice for three years, which was taken to be indicative of false pregnancy. Another female exhibited no elevation of progesterone levels through a one year period.

    CAPを3ヵ月または1週間毎に経口投与し猫の発情阻止が可能かどうかを検討した. 先ず, 成猫16頭に日量4-12.5mgを1週間連日投与し, これを3ヵ月毎に繰返したが, 投与終了後1~4ヵ月で10頭に発情が回帰した. 次に, 幼猫と成猫を含む28頭に2-12.5mgのCAPを1週間毎に経口投与すると, 少なくとも1年間全頭の発情を阻止することができた. 本法は体重に若干の増加を生じた他は何ら異常を認めず, 猫の発情阻止法として有効と考えられた.

    The histopathological changes related to chlormadinone acetate (CMA) implantation were examined using female beagle dogs given 10 mg/kg for four years. Estrus was completely inhibited in the CMA-implanted animals. In contrast, all control animals showed sign of estrus during the experiment, with periods of anestrus of normal duration. Histopathlogically, uterine sections from the CMA-implanted animals showed cystic glandular hyperplasia, but no histologic evidence of endometritis, myometritis, and pyometra was found. In the ovaries of the CMA-implanted animals, developing ovarian follicles were observed but no mature follicles were noted in addition to an absence of corpus luteum. No remarkable changes were observed in liver, adrenal, mammary gland, gallbladder, and implanted site. Furthermore, the intensity of staining and number of adrenocorticotropic hormone (ACTH)- and luteininzing hormone (LH)-positive cells in the pituitary sections of CMA-implanted animals were not different from the control animals. It was concluded, therefore, that subcutaneous implantation of CMA (10 mg/kg) is nearly equivalent to the minimal ovulation-suppressing dose.

    妊娠反応偽陽性にて発見されたhCG産生肺大細胞癌を経験したので報告する.
    症例は27歳, 女性. 高hCG血症, 胸部異常陰影を主訴に婦人科に入院し. 腹腔鏡下に妊娠ならびに原発巣は確認されなかったが, 肺転移をともなう絨毛癌の診断でMAC療法による化学療法を4コース施行された. hCG値は低下し腫瘍は縮小したが, hCG産生原発性肺癌の疑いで当科にて肺葉切除および縦隔リンパ節郭清を施行した. 病理組織診断は肺大細胞癌, p-T2N0M0, stageIBであった. 抗hCG抗体による免疫組織染色では細胞質が染色され, hCG産生肺大細胞癌と診断された. 術後54ヵ月経過した現在も再発なく生存中である.
