OSMOTIC RELATIONSHIPS IN THE HEN'S EGG, AS DETERMINED BY COLLIGATIVE PROPERTIES OF YOLK AND WHITE

Autor: Evelyn Howard

Publikováno v: The Journal of General Physiology

The osmotic pressure of the yolk and white of the hen's egg have been shown to be identical, by means of direct freezing point determinations, dialyses, and vapor pressure measurements. Dialysates of egg yolk slow the rate of ice formation compared w

Impairment of conditioned active avoidance in adult rats given corticosterone in infancy

Autor: Evelyn Howard, Craig T. Johnson, David S. Olton

Publikováno v: Developmental Psychobiology. 8:55-61

Intensive corticosterone treatment given to rats during the 1st postnatal week irreversibly decreases DNA accumulation in the cerebrum and cerebellum. After such hypercorticism in infancy rats were tested as adults in 2 conditioned active avoidance t

DNA, ganglioside and sulfatide in brains of rats given corticosterone in infancy, with an estimate of cell loss during development

Autor: Joyce A. Benjamins, Evelyn Howard

Publikováno v: Brain Research. 92:73-87

Evidence of a postnatal loss of cerebral cells has been presented, based on counts of the activity of cerebral DNA following labeling with [3H]thymidine on embryonic day 14. In otherwise untreated rats, the loss was about 15 percent of the labeled ce

THE RETARDING INFLUENCES OF ADRENALECTOMY AND AGE ON ESTRADIOL-INDUCED CONNECTIVE TISSUE HYPERPLASIA IN SEMINAL VESICLES1

Autor: J.C. Allen, Evelyn Howard

Publikováno v: Endocrinology. 60:785-796

ESTROGENS are known to stimulate hyperplasia of the fibro-muscular walls of certain portions of the male reproductive tract. In young castrated rats treated with estrogen, hyperplasia of fibro-muscular tissue in the seminal vesicles has been describe

Biological effects of 6-methyl-Δ5-androstene-3β-ol-17-one

Autor: Evelyn Howard

Publikováno v: Steroids. 5:255-259

Androgenic activity with respect to the phallus and preputial glands was exhibited by 6-methyl-DHA, but this was significantly less than the androgenic activity of DHA. No effect of 6-methyl-DHA on the rate of epiphyseal fusion was detected under con

Effects of Steroids on Epiphysiodiaphysial Union in Prepuberal Mice

Autor: Evelyn Howard

Publikováno v: Endocrinology. 72:11-18

A procedure for evaluating bone age in 4-week-old mice is described, based on examination under magnification of the alizarin-stained hindfoot, which at this age contains a number of areas undergoing epiphysiodiaphysial union. Untreated females were

THE EFFECT OF FATTY ACID BUFFER SYSTEMS ON THE APPARENT VISCOSITY OF THE ARBACIA EGG, WITH ESPECIAL REFERENCE TO THE QUESTION OF CELL PERMEABILITY TO IONS

Autor: Evelyn Howard

Publikováno v: The Biological Bulletin. 60:132-151

The effects of the pH of the medium on the apparent viscosity of Arbacia eggs have been studied by means of an adaptation of the centrifuge method.It was found that the degree to which fatty acids decrease the protoplasmic viscosity can be altered by

THE EFFECT OF ADRENALECTOMY ON THE ACCESSORY REPRODUCTIVE GLANDS OF MICE CASTRATED FOR SHORT PERIODS

Autor: Evelyn Howard

Publikováno v: Endocrinology. 38:156-164

THE ISOLATION of a number of sterols from cortical extracts has left unanswered the question as to what extent these sterols are normally secreted by the adrenal. In the case of the androgens, isolated from adrenal extracts by Reichstein (1936) and o
