Somatomedin levels measured by radioreceptor assay, competitive protein-binding assay or radioimmunoassay are normal in hypercortisolism; the decrease of somatomedin activity consistently found in this condition is due to an increase in circulating somatomedin inhibitors resulting in an inhibition of somatomedin action. Progestagens could possibly have

Nutrition and somatomedin XVI: Somatomedins and somatomedin inhibitors in fasted and refed rats
Metabolism, 1988Nutritional deprivation is associated with poor growth and decreased levels of net circulating somatomedin activity, as measured by bioassay. Since somatomedin activity reflects the contributions both of somatomedins (which stimulate cartilage) and of somatomedin inhibitors (which antagonize the ability of the somatomedins to stimulate cartilage), we ...

Bioassayable somatomedins and somatomedin inhibitors were examined after chromatographic separation, using serum from normal rats (enriched in somatomedins) and diabetic rats (enriched in somatomedin inhibitors). At neutral pH, gel filtration on Sephacryl S-300 revealed somatomedins at mol.

Normal Somatomedin and Somatomedin Receptors in Achondroplastic Dwarfism
Hormone and Metabolic Research, 1980It has been proposed that the basic abnormality in achondroplasia may be a quantitative defect in endochondral new bone formation secondary to decreased synthesis of somatomedin (SM) or abnormal binding of SM to specific receptors. To test this hypothesis, we have measured plasma SM levels and SM receptors on circulating mononuclear cells obtained from

Publisher Summary This chapter presents a personal approach to the somatomedins, from their beginnings as operationally defined activities to their emergence, in the last decade, as structural entities. The existence of other growth factors isolated from serum and tissue such as epidermal growth factor and platelet-derived growth factor are also ...

Although serum from normal rats has somatomedin (cartilage-stimulating) activity, serum from diabetic rats often lacks somatomedin activity and can inhibit somatomedin activity when added to serum from normal rats; this is attributed to somatomedin inhibitor (s).

Nutrition and somatomedin. XIII. Usefulness of somatomedin-C in nutritional assessment
The American Journal of Medicine, 1985Malnutrition is common in hospitalized patients, but current measures of nutritional status are limited. Because levels of somatomedins are regulated by nutrition, the utility of somatomedin-C measurement in nutritional assessment was studied. Thirty-seven malnourished patients had measurement of somatomedin-C and conventional nutritional indexes.

Metabolism, 1985
Diabetes is associated with poor growth despite elevated levels of growth hormone (GH). Skeletal GH effects are mediated by somatomedins; in diabetes, somatomedins measured by radioassay are normal, yet somatomedin activity measured by bioassay is low. Since bioassay measurements reflect the presence of both somatomedins and somatomedin inhibitors, we ...

The GH dependency of somatomedin (SM) peptide content in plasma was assessed using the placental membrane radioreceptor assay (RRA) to measure whole and acid-chromatographed plasma using both [125I]SM A and [125I]SM C. Plasmas from 10 normal children and adults, 11 GH-deficient children before and after therapy with 0.1 U/kg GH im daily for 5 days, and

Growth Hormone and Somatomedin
1974Publisher Summary This chapter provides an overview of the growth hormone and somatomedin. It is well established that growth hormone in vivo promotes skeletal growth and protein synthesis. Growth hormone promotes protein synthesis by stimulating the appearance in the tissues of a secondary factor, sulfation factor or somatomedin, which transfers ...
