Lead in human blood and milk from nursing women living near a smelter in Mexico City.

Lead levels in breast milk and blood were determined in women living within a 200-m radius of 3 smelters in Mexico City. All samples were analyzed on a Perkin Elmer 460 atomic absorption spectrometer equipped with HGA 2200. The mean blood lead level was 45.88 micrograms/dl (SD 19.88 microgram/dl), and the geometric mean of milk lead level was 2.47 micrograms/100 ml. The correlation coefficient of these two variables was 0.88. Using the mean value of lead found in breast milk, an infant of 5.5 kg would ingest 8.1 micrograms/kg/d in his diet. The daily permissible intake (DPI) established by the World Health Organization (WHO) in 1972 for an adult is 5.0 micrograms/kg/d.

The pituitary-gonadal axis in experimental nephrotic syndrome in male rats.

Basal and luteinizing releasing hormone-stimulated gonadotropin secretion were studied in male rats made nephrotic with puromycin, and in pair-fed and normal control animals. In addition, plasma concentrations of testosterone, androstenedione, estradiol, and estrone were measured in the three groups of animals. Urinary testosterone concentrations were also measured in the three experimental groups. The data showed that basal luteinizing hormone concentration was significantly elevated in the nephrotic group compared with the pair-fed and normal control groups. Gonadotropin response to luteinizing releasing hormone stimulation was not significantly different in the three groups, suggesting an intact hypothalamic-pituitary axis in nephrotic syndrome. Urinary testosterone concentration in the nephrotic animals was significantly higher than in the pair-fed and normal control groups. Plasma testosterone, androstenedione, estradiol, and estrone concentrations were significantly lower in the nephrotic and pair-fed animals than in the normal control animals, indicating possibly impaired gonadal steroidogenesis in these two groups that may be related to the catabolic state of the animals. It thus appears that urinary loss of protein-bound (sex hormone binding globulin-bound) testosterone in the nephrotic syndrome leads to increased basal secretion of luteinizing hormone, presumably as a result of increased luteinizing releasing hormone secretion. This occurs to compensate for the abnormal urinary testosterone loss and is an attempt to restore plasma testosterone concentrations to normal. The higher basal plasma luteinizing hormone concentration in the nephrotic group supports this conclusion.(ABSTRACT TRUNCATED AT 250 WORDS)
