The cytochemical bioassay system was described in a short abstract in 1971, and more fully, in the cytochemical bioassay of corticotrophin, in 1972. Since then, cytochemical bioassays have been described for several polypeptide hormones, and these assays are already widely used. It is expedient that the subject should be reviewed, as it is in this monograph, by one writer who has had the good fortune to have taken part in the growth of cytochemistry from its early origins to its present position as the basis of possibly the most sensitive bioassay system currently available. However, it...

The physiology and metabolism of thyroid hormones were areas of intense research investigation during the 1970s. Radioimmunoassays were applied to study the concentration of iodothyronines in biologic fluids. These techniques proved to be highly sensitive, specific, and reproducible as well as rapid. The availability of specific radioimmunoassays led to the detection of several iodothyronines in human biologic fluids, e. g., reverse triiodothyronine (rT 3), diiodothyronines, monoiodothyronines, and acetic acid derivatives of thyroxine (T 4) and T 3, which were previously either unknown or...

In the past 10 years hirsutism has been the object of a considerable number of fundamental studies. It provides endocrinologists with an experimental model for the investigation of androgen secretion, metabolism and mechanism of action. Plasma androgen assay, free testosterone measurement, hepatic and extrahepatic androgen metabolic clearance and androgen metabolism in the skin are the different steps which were studied by many groups and represent valuable parameters of the mechanisms of hirsutism. Determination of the origin of androgen oversecretion has become easier by technical progress...

The present monograph will concern itself with those disorders of the endocrine system, either associated with destruction, interference with function or hyper- function, which are considered to be due to auto-immune processes. Endocrinopathies Non-endocrine auto-immune disorders associated with the endocrinopathies Graves' (Basedow's, Parry's) disease Pernicious anaemia Hashimoto's thyroiditis Vitiligo Idiopathic Addison's disease Myaesthenia gravis Insulinopenic diabetes mellitus Sjogren's syndrome Auto-immune oophoritis and orchitis Rheumatoid arthritis Auto-immune hypoparathyroidism...

This monograph represents the first comprehensive review of hormones in human amniotic fluid and includes data published up to and including 1980. Recently, more extensive use of amniocentesis for prenatal diagnosis and evaluation of fetal lung maturation has shown that amniotic fluid hormone measurements can aid in the diagnosis of fetal and placental abnormalities. The material is presented in two main sections dealing with steroid and protein hormones. The methods of identification and quantitation are delineated, and the findings are discussed in relation to the clinical conditions. In...

The unraveling of our knowledge of the functions of the adrenal gland constitutes one exciting development of modern medicine and biochemistry. We owe these advances to the felicitous cooperative efforts of the clinical investigator and the biochemist. Three centuries elapsed between the first recorded anatomical descrip tion of the adrenals and the demonstration by Dr. Addison in the mid-nineteenth century of the fatal results of the destruction of these glands by disease. It became evident from this observation that the adrenals secreted a "factor" or "factors" essential to life. It took...

Lactogenic hormone activity was first observed in bovine pituitary extracts by Stricker and Griiter in 1928, working in Bouin's laboratory in Strasbourg. Since that time prolactin has been shown to exist in anterior pituitary extracts of almost all vertebrate species investigated. Although its biology was extensively studied in many mammalian species, the existence of prolactin in the human was generally doubted, despite the positive evidence produced by such researchers as Pasteels. This can partly be explained by the fact that human growth hormone isolated in 1961, is itself a potent...

Dr. Raymond Pederson, Dr. Jill Dryburgh and I commenced work on GIP in 1968, when, with the generous help of Professor Viktor Mutt and Professor Erik Jorpes of the Karolinska Inst, itute, Stockholm, we were able to establish that there existed an inhibitory material for acid secretion in cholecystokinin-pancreozymin prepara tions. Once the physiological evidence for the inhibitor was established it seemed appropriate to seek help in its isolation. Dr. J. Dryburgh and Dr. R. Pederson were left to bioassay fractions in Vancouver whilst I enjoyed the company of Professor Mutt at the Karolinska...

This monograph brings together our work concerning the relationships be tween the hypothalamus, pituitary and testis. The studies span approximate ly a decade of collaborative work. Over this period our contributions and those of many others have advanced greatly our understanding of many aspects of male reproductive biology. This monograph attempts to survey these developments and to highlight many unresolved issues. It also provides an opportunity to demonstrate the value of investigations which relate bio chemical to structural parameters and to illustrate the importance of animal studies...

Congenital adrenal hyperplasia (CAH) consists of a group of disorders of adrenal steroidogenesis. Each disorder results from an inherited deficiency of one of the several enzymes necessary for normal steroid synthesis. The different enzyme deficiencies produce characteristic patterns of hormonal abnormalities; the clinical symptoms of the different forms of CAH depend on the particular hormones that are deficient or that are produced in excess. The earliest documented description of CAH was by DeCrecchio in 1865 (DeCrecchio 1865). This Neapolitan anatomist described a cadaver having a penis...
