Serum alpha-fetroprotein concentration in adult patients under corticoid, estroprogestative or androgen therapy.

The serum alpha-fetoprotein concentration was measured by radioimmunoassy in 41 women with or without hormonal contraception, 21 patients with rheumatoid arthritis given corticosteroids or not, and 6 patients under androgen therapy for aplastic anemia. None of these therapies induced any significant variation of the serum alpha-fetoprotein level. More extensive studies are needed to investigate the possible effect of these hormones on the metabolism of this protein at a cellular level.

Contraceptive steroid toxicology in the Beagle dog and its relevance to human carcinogenicity.

Problems associated with the use of the Beagle dog in chronic toxicological studies of contraceptive steroids are described. A short review is presented on the occurrence of spontaneous tumours in dogs and in bitches of various breeds. The current status of knowledge of canine reproductive hormones and endocrinology is outlined, together with effects of contraceptive steroids. The pathology and histological classification of spontaneous and induced mammary neoplasia in the dog is discussed and compared with breast cancer in women. A series of recommendations are included for future research in this field which it is hoped may resolve some of the outstanding issues and lead to a more suitable toxicological model for contraceptive steroids.

Rheumatoid factor (antigammaglobulin) in women: effects of oral contraceptives use of its prevalence.

A total of 14,856 women, including 921 pregnant subjects, were tested for rheumatoid factor; 4,562 were using oral contraceptives at the time of testing. The prevalence of rheumatoid factor increased directly with age. The age-adjusted prevalence of rheumatoid factor was lower in oral contraceptive users than in nonusers but this difference was not statistically significant. Rheumatoid factor remained positive in 39% of subjects undergoing retesting after an average interval of 16 months. Those women with higher titers of rheumatoid factor were more likely to remain positive (81%). Of the women having positive tests, 5.4% were identified as having rheumatoid disease.

Bromocriptine for induction of ovulation in normoprolactinaemic post-pill anovulation.

19 women with anovulation after discontinuing oral contraceptive agents and with normal plasma-prolactin concentrations were treated with bromocriptine. Ovulation and menstruation were restored in 9 of the 13 amenorrhoeic and 5 of the 6 oligomenorrhoeic patients. The success-rate (74%) indicates that bromocriptine is an effective treatment for post-pill anovulation in normoprolactinaemic women.

Etiology, clinical features and prognosis in secondary amenorrhea.

A clinical investigation of 356 patients with secondary amenorrhea revealed that 95% of patients with postpill amenorrhea and 56% of patients with anorexia nervosa recovered in 6 years. The corresponding recovery rates for patients with psychogenic amenorrhea and amenorrhea following self-induced weight loss were 72% for both groups, and in patients with the amenorrhea-galactorrhea syndrome and idiophatic functional amenorrhea the recovery rates at 6 years were 64 and 61% respectively. Unlike the other groups with functional amenorrhea, patients with the amenorrhea-galactorrhea syndrome had impaired ovarian responsiveness to exogenous gonadotropins. Bromocriptine treatment resulted in disappearance of the galactorrhea and restoration of the menses and/or ovulation in nine of 18 patients; of these three became pregnant. The effect of bromocriptine did not persist for long after treatment ceased, and permanent recovery was recorded only in four patients. The group with functional amenorrhea included 34 patients who wished to become pregnant. Gonadotropin treatment was successful in 20 patients, clomiphene-hCG in two, tamoxifen in two, bromocriptine in two, and combined bromocriptine and clomiphene in one. Thus, the overall pregnancy rate in patients with functional amenorrhea was 79%. The groups with ovarian amenorrhea inclutients with assumed ovarian failure responded to large doses of exogenous gonadotropins by ovulation and three became pregnant. Ovarian wedge resection was ineffective in all five cases with polycystic ovaries, but two patients became pregnant after treatment with clomiphene and chorionic gonadotropin, and one with exogenous gonadotropins.

Problems in evaluating chronic toxicity of contraceptive steroids in dogs.

The long-term effects of oral contraceptive steroids including a combination of norethindrone and ethynylestradiol, a sequential regimen of dimethisterone and ethynylestradiol, and daily administration of megestrol acetate were studied in female beagle dogs at dose levels of 1, 10, or 25 times the projected human dose levels. The major findings included cystic endometrial hyperplasia and pyometra requiring hysterectomies and alopecia for the norethindrone-ethynylestradiol and dimethisterone-ethynylestradiol treated dogs. These groups did not have accentuated mammary development or treatment-related hyperplastic or neoplastic changes. For dogs given dimethisterone-ethynylestradiol, numerous acne-like lesions occurred in the skin of the mammary areas. Dogs given the higher dose levels of megestrol acetate had marked mammary stimulation, hyperplastic and neoplastic changes in the mammary glands, and clinical and pathologic changes typical of diabetes mellitus. Mammary changes of nodular hyperplasia, benign mixed tumor, and adenocarcinoma appeared as distinct entities although constant and intense mammary stimulation may be a common denominator. Such mammary changes have not been found in long-term studies in monkeys or rats with megestrol acetate, and the relevance of the canine mammary changes to projecting potential tumorigenesis in women is questioned.

[Changes in heparinocytes during the administration of Depositon and Sequenz-Ovosiston].

During hormonal contraception with Deposiston (once a week pill) and with Sequenz-Ovosiston (14 days mestranol 0.1 mg, 7 days mestranol 0,08 mg and 2 mg chlormadinone acetate) doesn't take place a change of basophil granulocytes (heparinocytes) in blood. Under Deposiston the small elevation is somewhat lengthened, under Sequenz-Ovosiston the elevated phase is similar to those of the normal menstrual cycle. The smaller risk of thromboembolia under heparinocytopenia preventing contraceptives is discussed.

[Modification of the thrombocyte function using hormonal contraception. 1. Thrombocyte count, thrombocyte propagation and platelet aggregation under hormonal contraception].

The number of platelets, spreading and aggregation of platelets in plasma of 102 women treated with Ovosiston, an anticonceptive agent, were investigated. A significant increase of the number of platelets, spreading and aggregation of platelets was observed. Conclusions from isolated observations are not possible.

Relations between fibrinogen degradation products and heparinocytes.

In the emergency reaction there is a short-time increase of the values of basophilic leukocytes in connection with normal values of fibrinogen degradation products (FDP). After diminuation of basophils FDP are to be detected. In the chronical ill and under different hormonal contraceptives these two processes are overlapped disturbing a unique negative or positive correlation of heparinocytes and FDP. Concerning the situation under standardized conditions or in single cases worthful conclusions are possible about compensation or decompensation of a latent disseminated intravascular coagulation.

[Liver function tests under the influence of sequential treatment using ethinyl estradiol-norethisterone acetate and ethinyl estradiol-chlormadinone acetate].

30 young healthy women were investigated during the first therapy cycle with ethinyl-estradiol-norethisterone acetate and ethinyl-estradiol-chlormadinone acetate as a sequential regime. The following laboratory data were achieved by each of the investigated group of young women: serum aminotransferase (GOT and GPT), serum alkaline phosphatase and alpha-amylase-activity in serum, serum proteins, serum cholesterol, serum bilirubin, serum ZST, serum TTT and the indocyaningreen-clearance of the liver. The serum protein pattern was determined by the paper electrophoretic method. A significant decrease of the aminotransferase GPT was viable during the sequential therapy with ethinyl-estradiol and norethisterone acetate. This viable decrease of the GPT was induced through the application of norethisterone acetate to estrogen. The alkaline phosphatase was significant lightly lower and the beta-globuline lightly elevated at the end of the therapy cycle. The sequential therapy with ethinyl-estradiol and chlormadinone acetate induced only a significant increase of the ZST in serum.
