Observations may serve to relate the known age-related decreases of melatonin production, the shift in the bone marrow toward an adipocytic line of cell development, and the development of osteoporosis during aging. Expand
Suppression of thyrotropin in the low-thyroxine state of severe nonthyroidal illness.

- The New England journal of medicine
- 28 February 1985
It is suggested that the low-thyroxine state of severe illness is the result of several events, one of which is failure of the normal negative-feedback control of the pituitary-thyroid axis due to illness-associated, decreased secretion of thyrotropin. Expand
Age differences in the water content of the body as related to basal oxygen consumption in males.
Chlorpropamide hyponatremia: drug-induced inappropriate antidiuretic-hormone activity.
Thyroid hormone elevations during acute psychiatric illness: relationship to severity and distinction from hyperthyroidism.
Elevations of T4, FT4I, T3, and FT3I are common among psychiatric inpatients, especially early in their hospitalization, and that levels of thyroid hormones are correlated with severity of psychiatric symptomatology are shown. Expand
Thyroxine turnover in euthyroid man with special reference to changes with age.
Hormone-sensitive fat cell adenylate cyclase in the rat. Influences of growth, cell size, and aging.
The possibility has been explored that decreases of adenylate cyclase may explain diminished hormone sensitivity of adipose tissue with aging. Isolated cells were prepared from epididymal fat pads of… Expand
Beta-adrenergic receptors, glucagon receptors, and their relationship to adenylate cyclase in rat liver during aging.
There appeared to be a beta-receptor-adenylate cyclase uncoupling in livers from the senescent animals (25-27 months), which apparently lies in an alteration of the interaction between the beta-adrenergic receptor and the guanine nucleotide-sensitive Ns protein. Expand
ADRENALIN AND HYDROXYTYRAMINE IN THE PAROTID GLAND VENOM OF THE TOAD, BUFO MARINUS
- R. I. Gregerman
- Biology, Medicine
- The Journal of general physiology
- 20 January 1952
Preparations from the parotid gland venom of the toad Bufo marinus have been analyzed by paper chromatography for the presence of adrenalin precursors. In addition to adrenalin itself,… Expand
Estimation of thyroxine secretion rate in the rat by the radioactive thyroxine turnover technique: influences of age, sex and exposure to cold.
- R. I. Gregerman
- Chemistry, Medicine
- 1 March 1963
Thyroxine secretion rate has been estimated in the rat using the radioactive thyroxine turnover technique, and the fractional turnover rate is greater in female than in male rats, both in the Osborne- Mendel strain of age 2–3 months and the Wistar strain of 12 months. Expand
