A radioimmunoassay method for urinary catechol estrogens.

A radioimmunoassay method for urinary catechol estrogens is described; The specific nature of the antisera allows direct analyses of acid hydrolyzed urine. A LH-20 Sephadex column chromatography can be employed for individual determinations of 2-hydroxyestrone and 2-hydroxyestradiol. The excretion of catechol estrogens during menstrual cycles ranged from 14.48 to 50.15 microgram per 24 hours, whereas, during the last trimester of pregnancies, the values ranged from 129.30 to 1758. 20 microgram per 24 hours.

Hepatotoxicity of erythromycin estolate during pregnancy.

Women in the second half of pregnancy, who were infected with genital mycoplasmas and who gave written informed consent, were randomly assigned to receive capsules of identical appearance containing erythromycin estolate, clindamycin hydrochloride, or a placebo for 6 weeks. Levels of serum glutamic oxalacetic transaminase (SGOT) were determined before and during treatment by a fluorometric method. All pretreatment levels of SGOT were normal (<41 units). Participants who received erythromycin estolate had significantly more abnormally elevated levels of SGOT (16/161, 9.9%) than did those who received clindamycin (4/168, 2.4%, P < 0.01) or those who received placebo (3/165, 1.8%, P < 0.01). Elevated levels of SGOT ranged from 44 to 130 U. Serum bilirubin levels were normal. Gamma-glutamyl transpeptidase activity was abnormal in six of six participants who had abnormal levels of SGOT while receiving erythromycin estolate. There were few associated symptoms, and all levels of SGOT returned to normal after cessation of treatment. The treatment of pregnant women with erythromycin estolate may be inadvisable.

Urinary progesterone as an index of ovulation and corpus luteal function.

Urinary excretions of progesterone (P) during normal menstrual cycle have been measured by radioimmunoassay. The excretion pattern mimics that of plasma P. Measurements of P in a single voided urine may be a reliable substitute for plasma analyses in the evaluation of ovulation and corpus luteal function.

Familial aggregation of blood pressures of newborn infants and their mother.

The blood pressures and pulse rates of 257 normal full-term infants and their mothers were measured two to four days after birth. Birthweight was correlated with systolic (P=.038), but not with diastolic blood pressure. Infants who were asleep had significantly lower systolic and diastolic blood pressure than infants who were awake (P less than .001). Sex, body length, and feedings did not appear to influence infant's blood pressure nor did the anesthesia given to the mothers. Maternal diastolic pressure correlated with infant's diastolic pressure (regression coefficient, .128) (P less than .01), whereas for systolic pressure the regression coefficient between maternal and infant pressure was .085 (P=NS). The aggregation between the diastolic blood pressures of infants and mothers was not influenced by birthweight, age of the mother, or medication administered to the mother. The pulse rates of black infants were significantly higher than those of white infants (P less than .002). There was no correlation between the pulse rates and blood pressures in infants.
