The potential developmental toxicity of temafloxacin hydrochloride was studied in the long-tailed macaque (Macaca fascicularis). Ten animals in each of the three drug-treated groups (25, 50, and 100 mg/kg) were administered temafloxacin via nasogastric intubation during gestational days (GD) 20-50. A control group of ten animals received vehicle only. The dams were monitored daily for adverse physical signs and maternal blood samples were collected for analyses of serum progesterone (P), 17 beta-estradiol (E2), and chorionic gonadotropin (CG). In addition, the conceptus was monitored periodically by ultrasound during gestation to confirm growth and viability. Increased maternal toxicity (weight loss, anorexia, emesis) and embryolethality were observed at 100 mg/kg, and a no-observable-adverse-effect-level (NOAEL) of 50 mg/kg was established. The incidence of prenatal mortality was as follows: Control = 1/10 (10%); 25 mg/kg = 1/10 (10%); 50 mg/kg = 2/10 (20%); and 100 mg/kg = 5/10 (50%). Analysis of P, E2, and CG indicated no significant effect of treatment. In addition, no significant differences were observed in embryonic/fetal growth and development when compared to historical controls. No gross structural changes were observed in fetuses exposed to 50 or 100 mg/kg, although one fetus exposed to 25 mg/kg exhibited microphthalmia. This anomaly was considered spontaneous and, therefore, unrelated to treatment.

Forty-eight patients with advanced gastric cancer and measurable areas of malignant disease were treated with etoposide (130 mg/m2/day X 3 days) plus cisplatin (45 mg/m2day on days 2 and 3). Both drugs were given by constant intravenous infusion and repeated every 4 weeks. Common toxic reactions included nausea, vomiting, diarrhea, alopecia, peripheral neuropathy, leukopenia, and thrombocytopenia. Most patients experienced severe but reversible toxic reactions. In 46 evaluable patients an overall objective regression rate of 28% was obtained with a median duration of regression of 4 months. Regression rates were only modestly reduced among patients with prior chemotherapy exposure (21%). Whereas this combination of etoposide and cisplatin does not appear to offer any major advantage over other single and combination regimens in the treatment of advanced gastric cancer, it shows definite activity and its lack of cross-resistance with other commonly used agents for this disease could indicate a possible role in new combination or sequential chemotherapy approaches. As an interesting sidelight, we found that 21% of our patients had elevated human chorionic gonadotropin (HCG) levels, and among this group regression rates were higher than in HCG-negative patients. It would be of interest to extend these observations in other gastric carcinoma studies involving cisplatin regimens.

A combination of the antigestagen mifepristone (RU 486) and a synthetic prostaglandin analogue, gemeprost, was used to induce therapeutic abortion in 100 women in early pregnancy. Local family planning services and general practitioners in Edinburgh referred women of less than 56 days' amenorrhea who had requested abortion. Pregnancy was confirmed by measurement of the serum level of human chorionic gonadotropin. Group I (n=20) received 150 mg mifepristone orally each day for 4 days. Groups II (n=30), III (n=30), and IV (n=20) received a single oral dose of mifepristone, 400 mg, 500 mg, or 600 mg, respectively. Samples of peripheral blood were collected at recruitment for measurement of the concentration of hemoglobin, urea, electrolytes, cortisol, and HCG and for liver function tests. Blood also was taken for estradiol and progesterone essay from women in Groups II, III, and IV. Each woman recorded symptoms in a diary from the day prior to the start of treatment. Study participants were reviewed 1, 2, and 4 weeks after treatment and discharged from followup after the onset of the next menstrual period. The effectiveness of the 4 treatment regimens was similar. Only 10 (14%) of the 74 women who received half a gemeprost pessary required the 2nd half. 95 of the women aborted completely; 5 women needed surgical intervention. Data were pooled for analysis because there was no significant difference between the 4 groups in the onset of bleeding and pain, requirement for analgesia, side effects, duration of bleeding, measured blood loss, and the time until the next menstrual period. The 94 women who experienced pain became aware of pelvic discomfort 46.6 hours after the initiation of treatment. No patient needed analgesia during the first 48 hours of treatment. After insertion of the pessary, 44 women received an oral analgesic drug and 9 an intramuscular opioid. 47 women did not need an analgesia. There was no significant difference in the frequency of nausea before and during treatment, but there was a significant increase in the incidence of vomiting and of diarrhea. 30 women vomited after the pessary was inserted compared with 13 the day before treatment; 10 women had diarrhea compared with 3 before treatment. No women had clinical evidence of pelvic infection. Liver function tests and cortisol levels were similar prior to and following treatment. Levels of HCG, and estradiol and progesterone decreased significantly after treatment. There were no significant differences in the results between those who needed evacuation and those who did not.

Two studies were conducted to assess factors associated with increased risk of hyperemesis gravidarum during pregnancy with data and serum samples collected from participants in the Collaborative Perinatal Study. In the case-control study, 419 pregnant women with hyperemesis gravidarum were matched on medical center, date of study registration, and race with 836 pregnant women who did not vomit during the index pregnancy. Younger age, nulliparity, and high body weight were significantly associated with increased risk of hyperemesis. Women with hyperemesis had significantly reduced risk of fetal loss; however, their infants had higher risk of central nervous system malformations. In the second study, first-trimester pregnancy hormones were measured in the serum of 35 women with hyperemesis and 35 control women who were individually matched to cases on age, parity, and medical center. After adjusting for length of gestation, mean levels of total estradiol were 26% higher and mean levels of sex hormone binding-globulin binding capacity were 37% higher in patients with hyperemesis gravidarum than in control subjects. These differences were statistically significant. Although human chorionic gonadotropin concentrations were higher in control pregnancies, the differences were not statistically significant. The average amount of estradiol that was nonprotein bound (adjusted for length of gestation) was also higher in patients than in control subjects. These results are consistent with the hypothesis that elevated estrogen levels are responsible for excessive vomiting in pregnancy.

In order to investigate further the endocrine and metabolic features of the common condition emesis gravidarum, serum concentrations of some non-steroid hormones and tissue polypeptide antigen (TPA) were determined in 102 healthy pregnant women. 62 complained of nausea and vomiting in early pregnancy. Significantly higher and lower levels of human chorionic gonadotropin were noted in early and late pregnancy, respectively, in women with emesis gravidarum. A significant rise in serum prolactin and TPA was found throughout pregnancy in all subjects, no differences between emetic and non-emetic pregnancies being registered. Serum concentrations of growth hormone (hGH) showed a significant decline as pregnancy advanced. Emetic women demonstrated higher hGH levels in late pregnancy than did asymptomatic subjects. Free T4 concentrations remained stable when comparing early with late pregnancy, no dissimilarities being found between women with and without nausea and vomiting in pregnancy. These data do not support the hypothesis of major metabolic disturbances as an etiologic factor for nausea and vomiting in pregnancy. However, as overt differences between emetic and non-emetic pregnancy were found, hormonal factors may be involved in the pathogenesis of this condition.

In most developed countries in which therapeutic abortions are legal, termination of pregnancy is performed at between 8 and 12 weeks of gestation. Because the complication rate after this procedure rises with increasing gestation, there would be many advantages in inducing abortion before the eighth week ('menstrual induction'). With the increasing availability of highly sensitive methods of detecting human chorionic gonadotropin, pregnancy can now be diagnosed as early as 10-14 days after conception. The uterus can be surgically evacuated safely and simply by suction aspiration under local anaesthesia. However, a safe and effective method of inducing abortion by medical means would be a useful and cheaper alternative. Of the potentially useful compounds, only derivatives of prostaglandins E and F administered by vaginal pessary have so far been shown to be effective. Although the rate of haemorrhage and infection is low, 10-30% of women experience moderate side-effects of pelvic pain, diarrhoea and/or vomiting. The possibilities are discussed of reducing the incidence of side-effects by different methods of release or using prostaglandins in combination with other compounds such as antigestogens which might lower the therapeutic threshold.

A 7-year-old boy was admitted to Hokkaido University Hospital complaining of headache and vomiting. On admission he was slightly confused and presented Parinaud's sign. CT scan revealed abnormal high density mass with contrast enhancement effect at the pineal region and obstructive hydrocephalus. Laboratory studies showed the normal value of human chorionic gonadotropin and no trace of alpha-fetoprotein. Germinoma was most suspected based on the findings of CT scan and laboratory studies. The radiation therapy was carried out for a month and CT scan taken after the radiation therapy revealed marked reduction of the size of the tumor at the pineal region, and he was discharged. But he was re-admitted 3 months after the discharge complaining of headache and vomitting again. CT scan showed the recurrence of the tumor and laboratory studies showed abnormal high value of A.F.P. After the ventriculo-peritoneal shunt, the sub-occipital craniectomy was performed by the Stein's approach, and the tumor was removed. Pathologically the tumor was a typical yolk sac tumor. This case is a very interesting case because it suggests an alternation of the element of the germ cell tumor by the radiation therapy. At first admission, germinoma was the main element of the tumor judging from the effectiveness of the radiation therapy and laboratory studies. But the main element of the tumor seemed to have changed to yolk sac tumor after the radiation therapy. The relation between the tumor markers and the types of the germ cell tumor and histopathological characters of the intracranial germ cell tumor were discussed.

The clinical characteristics and applicability of vaginal administration of a single suppository of (15S)-15-methyl prostaglandin F2alpha (PGF2alpha) methyl ester in postconceptional induction of menses was evaluated in 14 healthy women who were no more than 7 weeks pregnant and desired pregnancy termination. Each suppository contained 3.0 mg of 15S-15-methyl PGF2alpha methyl ester in a 2.2 gm base of Witepsol E-76-A. Blood samples were collected at 0, 4, 8, and 10 hours and again at the 14th day follow-up visit for analysis of serum chorionic gonadotropin (HCG) levels using the Beta subunit radioimmunoassay as described by Vaitukaitis et.al. and serum progesterone levels using the radioimmunoassay method of Kirton et.al. Pregnancy termination was successful in all but 1 patient. Vaginal bleeding persisted for at least 14 days in 8 cases; 2 of these patients necessitated curettage at 4 weeks and 9 weeks after the procedure. The failed case was an obese woman whose pregnancy persisted. HCG levels declined below the arbitrary limit of 1 I.U./ml within 2 weeks after therapy in 36% of the cases. Plasma progesterone levels declined below the baseline level of 5 ng/ml within 2 weeks. A wide range of values was observed at 4 and 8 hours. The 1 failure case had an initial value of 72 pg/ml at 4 and 8 hours; all cases with undetectable levels at 8 hours had initial values over 138 pg/ml. In patients with prolonged bleeding, serum HCG and progesterone showed a significantly slower decline than in patients with an uneventful abortion. Diarrhea occurred in 86% of the cases and vomiting in 36%. The study illustrates the effectiveness of administration of 1 vaginal suppository containing 3.0 mg of PGF2alpha methyl ester in 1st trimester abortion. However, the bleeding and gastrointestinal side effects associated with this method preclude its widespread use.

RU 486, a new antiprogestational compound, was given to 37 women seeking termination of pregnancy and with amenorrhea of 42 days or less. 1 patient was found at the 2nd follow-up visit to have an extrauterine pregnancy. The patients received either 25 mg, 50 mg, or 100 mg RU 486 twice daily for 4 days. All patients attended 3 follow-up visits, 1, 2, and 5-6 weeks after the start of therapy. The start, duration, and amount of bleeding as well as plasma progesterone, beta-human chorionic gonadotropin (hCG) and cortisol concentrations were determined for each treatment day and at follow-up visits. All but 3 patients started to bleed during treatment. Frequency of complete abortion was 61% (22 of 36 patients). In only 3 patients was the pregnancy unaffected by treatment. The clinical efficacy of the treatment was not dose-dependent. Most of the patients experienced only minor dise effects in terms of mild uterine pain, nausea, and vomiting. However, 2 patients suffered from heavy bleeding requiring blood transfusion and curettage. In patients with complete abortion, beta-hCG values decreased significantly but not until the 1ft follow-up visit. The plasma progesterone also decreased. This decrease appeared earlier with the higher daily dose of RU 486. Cortisol concentrations increased during treatment with all 3 dosage regimens but the levels remained within the normal range. It is concluded the treatment with RU 486 may provide a novel therapy for menstrual regulation but the efficacy of it needs to be improved to compete with such alternatives as vacuum aspiration.

The knowledge and use of newer, more sensitive, and reliable pregnancy tests which are easily accessible and of moderate cost are the 1st steps in the early diagnosis and management of pregnancy, especially in adolescent girls. Accurate diagnosis of pregnancy soon after conception offers the option of abortion by simple, effective, and inexpensive procedures or early initiation of prenatal maternity care. Discussion focuses on the symptoms of pregnancy and the historical development and basis of pregnancy tests as well as the specific types of pregnancy tests. The most familiar sign of pregnancy is the missed period. Other symptoms that provide presumptive evidence of pregnancy include fatigue and lassitude, increased body temperature, and breast fullness or pain. Feelings of nausea, vomiting, and weight gain may appear after 2 weeks. The diagnosis of pregnancy by the detection of the human chorionic gonadotropin was initially described 53 years ago by Selmar Aschheim and Bernhardt Zondek. Improvements in the techniques for the measurement of human chorionic gonadotropin (hCG) have been directly related to the progress in the purification and isolation of hCG and elucidation of the amino acid sequence of the hormone-nonspecific alpha subunit and hormone-specific beta subunit of hCG. The history, physical examination, and pregnancy tests will generally provide sufficient information for a definite diagnosis of pregnancy. The presence of hCG in the urine or blood is the most accurate of all the indications of pregnancy. During the last century, 4 different techniques for the determination of hCG in blood and/or urine have been developed. These include the following and are reviewed in detail: 1) bioassays in intact laboratory animals; 2) immunologic tube or slide methods with heme- or latex-agglutination inhibition, as well as the more recently developed competitive protein binding method such as 3) radioimmunoassay (RIA) for the use of radioisotope labeled hormone and the specific antiserum against hCG; and 4) radioreceptorassay by the use of radioisotope-labeled hormone with biological activity and the specific receptors as the binding proteins.
