Blood transfusion in peace and war, 1900-1918.
The practice of blood transfusion became commonplace in the first half of the twentieth century, a time that coincided with the practice of war on a hitherto unprecedented scale. A close examination of the process reveals that it was not a simple one of war acting as a stimulus to scientific and medical discovery. Most innovations had their origins in the United States before the war, whose main effect was to diffuse and perfect transfusion through greatly increased use of the technique. The result was that in less than twenty years blood transfusion changed from being a medical curiosity and procedure of last resort to a practical and relatively simple treatment that demonstrated its value in saving thousands of lives.

The history of research on blood group genetics: initial discovery and diffusion.
During the 1920s and 1930s the resting of blood groups for large numbers of people became a very common practice. Although much of this was to ensure compatibility for blood transfusion, over 1,000 articles were published with results of tests on over 1.3 million people to answer more theoretical, scientific questions. The motivation for much of this research was the possible link between the well established hereditary blood types and other possible inherited traits. Because the existence of the blood groups was a rather sudden discovery, the record of this publication offers an excellent case study of the diffusion of new scientific knowledge. Differences in the beginning of blood group research from country to country reveal some important influences of social setting on the spread and application of the new discoveries.

[Additive therapy in ovulation induction with clomiphene].
Between 1977 and 1981 1319 patients consulted our hospital with the problem of sterility. 763 women became pregnant, 200 were treated with clomiphen . In 69 cases we used a combination with other agents, because ovulation could not be induced with clomiphen alone. 7 times we combined clomiphen with HCG, in 7 other cases with Prednisolon . Ovulation and pregnancy occurred subsequent to a treatment with Estradiolvalerianate -Norgestrel and clomiphen in 15 patients, in 32 patients after administration of a combination of clomiphen and Bromocriptine. The inadequate cervical mucus which may develop in patients during clomiphen therapy was treated with an additional low dose of ethinylestradiol. Our retrospective study confirms the value of a combination therapy in the treatment of anovulation and sterility.

[Molecular-biological studies of the cervical secretion with one-dimensional electrophoresis].
In the present study the polypeptide composition of cervical mucus was analysed during the human menstrual cycle. Changes in the polypeptide profile as displayed by a very sensitive silverstaining method were consistent with cycle dependent variations in observed rheological properties of the mucus and activities (concentrations) of luteinising hormone (LH) (from comparatively analysed blood). It could be shown that whereas three main polypeptide components of the mucus (50 kd [kilodalton], 14 kd, 12 kd) remained constant the amount and intensity of other polypeptides increased towards midcycle (ovulation) and diminished on the days after ovulation. A 25 kd polypeptide (being a main component on the days before ovulation) disappeared at midcycle (on the day of ovulation). On the same day a new main peptide (8 kd) was observed, which was decreasing (in favour of the 25 kd peptide) on the days after ovulation. It is postulated that the described shift in the polypeptide pattern of the cervical mucus may be a result of the degradation of the light chain of IgG at midcycle.

[Clinical experiences with the prolactin-inhibiting serotonin antagonist metergoline].
20 puerperal women who did not wish to breast feed their infants were treated with the serotonin antagonist metergoline. In 19 cases effective suppression of puerperal lactation was achieved by the administration of metergoline without the side effects or signs of intolerance. Of 9 women with hyperprolactinaemic amenorrhoea treated with metergoline the raised prolactin level was lowered, followed by menstruation in 7 patients. Ovulation even occurred in 5 of these women. One patient had to discontinue therapy due to intolerance. in normoprolactinaemic amenorrhoea regular menstruation reappeared in 4 out of 5 women; 2 patients even ovulated.

[The incidence of congenital abnormalities following gestagen administration in early pregnancy (author's transl)].
198 women who had been trying for years to have a baby were submitted to a trial of prophylactic allyloestrenol therapy in an attempt to lower the incidence of spontaneous abortion. Allyloestrenol (Gestanon) was given at a dosage of 10 mg daily until the 8th week of pregnancy; the dosage was then stepped up to 15 to 20 mg daily until the 12th week of pregnancy and then rapidly tailed off. A decrease in the miscarriage rate was seen only in the group of women in whom treatment had been commenced immediately following ovulation (27 women: 1 miscarriage). If therapy was initiated only after the first missed period then it was without effect (161 women: 23 miscarriages). There were 4 cases of severe congenital abnormality; 3 of these cases arose in the group given allyloestrenol immediately after ovulation (with a drastic reduction in miscarriage rate). The results are discussed. They speak against a cytotoxic effect of the gestagen. It appears likely that the lowering in miscarriage rate occurs at the expense of a failure to prevent the nidation of abnormal fetuses who would normally be aborted.

[Clinical experience with danazol treatment of endometriosis and mastopathy].
26 women presenting with internal and external endometriosis and 27 women with chronic cystic mastopathy and mastodyny received 400 mg danazol-a 17-ethinyltestosterone derivate-daily for 3 to 6 months. Before, during and after completion of treatment clinical and endocrinological investigation as well haematological examinations and determinations of blood and urinary chemistry were carried out. In cases of mastopathy plate thermography and mammography were performed; in endometriosis the diagnosis was verified by laparoscopy or-tomy. An improvement in, or disappearance of dysmenorrhoea and pelvic pain was observed in the endometriosis group. At laparoscopy or -tomy a decrease in, but not a complete disappearance of endometriotic foci was seen. A most favourable effect of danazol was seen in mastodyny. A change in plate thermographic or mammographic findings was observed on only a few patients. A significant fall in 17 beta-oestradiol after one month and a slight decrease in basal LH levels (statistical trend) were observed. FSH and HPRL levels were not significantly affected. Ovulation was mostly suppressed, but serum progesterone values were found several times to be in the range characteristic of severe luteal insufficiency (100 to 1500 pg/ml). Hence, not only amenorrhoea, but also breakthrough bleeding occurred. The observed side affects can be ascribed to anabolic (weight gain), androgenic (acne, hirsutism) and hypoestronic (atrophic vaginitis, hot flushes, restlessness) symptomatology.

[Hypophyseal reaction state during oral contraceptiva (author's transl)].
In 5 normocyclic women, firstly taking a conventional oral contraceptive, Neogynon (50 mcg EE + 250 mcg levo-norgestrel) for 6 months, the levels of LH, 17 beta-E2 and progesterone did not rise after changeover to a dose-reduced pill, Microgynon 30 (30 mcg EE + 150 mcg levo-norgestrel). This fact indicates maintained central suppression. Examination of the hypothalamic-hypophyseal axis by the Gn-RH test (50 mcg) with Microgynon 30 showed negative results during the first treatment cycle in 13 out of 18 women. In the 6th treatment cycle only 7 Gn-RH non-reactive women were observed and after stimulation with 100 mcg Gn-RH only 5 women remained with negative Gn-RH tests. Of the 20 women who took conventional oral contraceptives over a period of 6 months to 6 years (7 took Eugynon: 50 mcg EE + 500 mcg D,L-norgestrel, 5 Lyndiol: 75 mcg mestranol + 2.5 mg lynoestrenol, 8 Neogynon, only one from the Neogynon group showed a positive result. On the other hand there was a positive reaction in 4 out of 7 women using the two step dose-reduced preparation Sequilar (11 tablets of 50 mcg EE + 50 mct levo-norgestrel and 10 tablets of 50 mcg EE + 125 mcg levo-norgestrel).

[The efficacy of gestoden (delta 15-d-norgestrel) as ovulation inhibitor (author's transl)].
Two single-phase combined low-dosage oral contraceptive preparations were tested with respect to their effects on functional parameters of the menstrual cycle. Twenty young women with a normal biphasic menstrual cycle took part in this random study. Evaluation of cervical function, consistency and crystallisation ability of the cervical mucous and of the karyopyknosis index as well as radioimmunoassay of the serum levels of LH, FSH, HPRL, 17-beta-oestradiol and progesterone were carried out consecutively as from the 8th day over the duration of one control cycle and one in which contraceptive as administered. Preparation I (SH D 356 A) contained 75 micrograms delta 15-d-norgestrel (Gestoden) + 30 micrograms ethinyloestradiol. Whilst preparation II (SH D 356 B) contained 75 micrograms d-norgestrel + 30 micrograms ethinyloestradiol. Both substances successfully inhibited ovulation, whereby the former achieved a markedly greater suppression of function with regard to all parameters and, yet good menstrual cycle control was maintained. Hence, gestoden enables the content of active components in oral contraceptives to be reduced even further without detracting from the safety of the technique.

[Intrauterine contraception with copper-T 200 device- a retrospective analysis of 334 cases (author's transl)].
A review is given of the findings obtained in 334 women in whom a Cu-T 200 intrauterine device had been inserted at least two years previously and regular follow-up examinations were subsequently undertaken. The most frequent indications were an expressed preference for IUD on the patient's part (38.3%), poor tolerance to the "pill" (24.8%) and so-called "pill fatigue" (11.1%). Varicose veins led to IUD preference in 8.1% and thromboembolic disease in 6.-%. The failure rate - with 12 pregnancies - was 3.6%, all within 6 months of insertion of the device. Half of the pregnancies went to full term and resulted in the birth of mature, healthy babies. The most frequent complication were menstrual disturbances (20.1%). pain (19.5%), cervicitis (18.3%), and adnexitis (13.8%), necessitating removal of the device in 5.7%, 4.2%, 5.1%, and 0.6% of all cases for the afore-mentioned reasons, respectively. These rates are relatively high. The expulsion rate of 2.7% was relatively low, however. Further analysis of the complications led to the observation that menorrhagia was relatively common in nulliparae and in women with retroversion of the uterus, whereas the pre-insertion finding of a pressure-sensitive uterus with a normal ESR, led in a significantly higher percentage of cases to pain and adnexitis. The diagnosis by vaginal probe of a reduced uterine length led to faulty positioning and an increased tendency to pain in a significantly higher number of cases. The fact that only 56.6% of all women tolerated intrauterine contraception well and remained totally symptom-free supports th view held by us that even today the "pill" remains the contraceptive of choice and should be recommended as such.

[Timing of ovulation in clomiphene-induced cycles (author's transl)].
214 menstrual cycles, induced by clomiphene in 121 women desiring a family but manifesting disturbances of cycle, type WHO II (1976) were investigated with regard to pattern of cervical function. 184 were ovulatory cycles. The time of ovulation was predictable within a range of two days in 58.7% of cases by means of the cervical score, consisting of the dilatation of the cervical os, the degree of transparency, the quantity and the consistency of the cervical mucus. The occurence of the "LH peak" and the rise in basal body temperature (BBT) were set in relation to this. In 41.3% of cycles the cervical score, influenced by the antioestrogenic effect of clomiphene, gave only insufficient evidence. In subsequent treatment cycles the cervical function, in relation to the individual case and the inducible quality of the cycle, showed a similar response rate as in the first treatment cycle. Our results suggest that, after examination of the first clomiphene-induced cycle by the combined means of cervical score and hormoneanalytic methods, patients with a positive cervical response, can be investigated by any interested doctor, even if he doesn't have a laboratory at his disposal, in order to assess the timing of ovulation for therapeutic measures.

[Treatment of infertile couples--an interdisciplinary task (author's transl)].
The results obtained by closest cooperation between gynaecologist and andrologist in the treatment of sterile marriages are reported. 127 couples were treated over a period of 20 months. Almost 100% of the males and 60% of the females were sub- or infertile. Treatment of both partners was meticulously coordinated in order to increase the success ratio. Interdisciplinary cooperation seemed to be advantageous particularly in homologous insemination. 23 pregnancies were achieved, i.e. 18.1%, despite the unpromising nature of this negatively selected material.

[Contraception in preclimacteric women with special regard to oral contraceptives (author's transl)].
During a period of 9 years 143 women at an age over 40 attended for the first time the I. University Clinic of Gynecology and Obstetrics in Vienna for receiving contraceptive treatment. 71 women (49.6%) received oral contraceptives wiD was inplanted because of either internal contraindications of oral contraceptives (mainly high risk for thrombosis) or negation by the patient. 16 patients were sterilised, mostly with the laparascope. The main side effects in the patients receiving oral contraceptives were nervosity, impairment of libido and complaints in the lower extremities. 60.5% of all women over the age of 40 using oral contraception didn't show any complaints. On the basis of the own results and the reports in literature the advantages and disadvantages of oral contraception in comparison with mechanical devices are discussed.

[Hormonal and functional parameters in hyperprolactinaemia (author's transl)].
58 women with raised serum prolactin levels and normal hypophyseal-X-ray parameters were subdivided into three groups according to the serum prolactin level (16 to 40, 41 to 80, greater than 80 ng/ml). In addition to the determination of LH, FSH, oestradiol, progesterone and testosterone in the serum and thyroid diagnostic procedures the following hormonal tests were performed: 1. response to gestagen; 2. response to clomiphene; 3. Gn-RH-test for hypophyseal function; 4. ovarian response to administered gonadotropins (only in cases with prolactin levels greater than 80 ng/ml). The grade of menstrual cycle disorders depends on the severity of the observed hyperprolactinaemia. Slight disorders like luteal phase insufficiency, anovulatory cycle and oligomenorrhoea are associated with low- or medium-grade hyperprolactinaemia. Mainly secondary, but also primary amenorrhoea is found in cases with higher serum prolactin levels (greater than 80 ng/ml). In these cases the hypophyseal response to Gn-RH is frequently found (61%) to be negative and, moreover, the ovarian response to administered gonadotropins seems to be diminished. Increasing HPRL levels often appear to be associated with a negative response to the other above-mentioned tests.
