Plasma prolactin, human chorionic gonadotropin, estradiol, testosterone, and progesterone in the ovarian hyperstimulation syndrome.

Plasma prolactin, estradiol, progesterone, and testosterone, but not HCG-beta levels, were higher in a patient who developed the ovarian hyperstimulation syndrome while undergoing ovulation induction with human gonadotropins than in two other women who also became pregnant after similar treatment without complications. These results suggest that hyperprolactinema, in association with elevated ovarian steroid levels, may be factors in the pathogenesis of this disorder.

Benign mixed tumor of the trachea.

A case of mixed tumor, salivary gland type, removed by segmental resection of the trachea is reported. Only thirteen acceptable and five probable tracheal mixed tumors have been found in the world literature. The behavior of this variety of tumor in the trachea appears to be similar to its counterpart in other sites and distinctly different from the more frequently encountered epithelial tumors: squamous cell carcinoma and adenoid cystic carcinoma.

Seasonal fluctuations in the plasma concentrations of progesterone and oestradiol-17 beta in the female snapping turtle (Chelydra serpentina).

Plasma concentrations of progesterone and oestradiol-17 beta were determined by radioimmunoassay procedures in the sexually mature female snapping turtle at four different stages of the annual ovarian cycle. The highest level of progesterone in the peripheral plasma was detected during the luteal stage (June), whereas the concentration of oestradiol was highest (280 pg/ml) in May, immediately before ovulation.

The routine application of a microtechnique for the demonstration of leptospiral antibodies.

The microtechnique of Galton et al. (1965) for the routine screening of blood samples for leptospiral antibodies was used to examine more than 8000 serum samples from animals that had aborted and from herds in which leptospiral antibodies had previously been demonstrated. The method gave consistently accurate results. In respect of ease and speed of performance, it was superior to the microscopic agglutination test and it required only minute volumes of serum and antigen suspension. Its most important advantage was that the agglutination reaction could be read directly on the plate, and the removal of samples for microscopical examination was therefore unnecessary.

The Mehrabian measures of achieving tendency: are separate male and female scales necessary?

The 1969 male and female Mehrabian measures of achieving tendency are among the best-known measures of resultant achievement motivation. This study addressed the question of whether unique male and female items are necessary. Pearson product-moment correlation analyses on 83 male and 184 female undergraduates showed that females' scores on the unique male items correlated positively with their scores on the original female scale, and males' scores on the unique female items correlated positively with their scores on the original male scale. Coefficient alpha reliabilities of the original male and female forms were found to be acceptable. Cluster analyses showed that the Mehrabian items cluster in very similar ways for both males and females.

Sensitivity of mycoplasmas of the respiratory tract of pigs and horses to erythromycin and its use in selective media.

The ability of erythromycin in liquid medium to suppress the growth of eight species of acholeplasma and of 13 species of mycoplasma was tested. The Acholeplasma spp and two glycolytic Mycoplasma spp from horses--a slow glucose-metabolising (SGM) mycoplasma and a strain N3, related to M mycoides--were sensitive to erythromycin. Thus the growth of acholeplasmas can be suppressed when attempts are made to isolate pathogens from the porcine respiratory tract, but, in the case of horses, erythromycin would suppress not only Acholeplasma spp but also two Mycoplasma spp of unknown pathogenicity in the equine respiratory tract.
