Growth hormone (GH) assays: influence of standard preparations, GH isoforms, assay characteristics, and GH-binding protein.
The impact of the adoption of the new biosynthetic growth hormone (GH) WHO International Reference Preparation (IRP 88/624), and the recommendation to report results in microgram/L instead of mU/L, is described. Conversion factors were determined by comparing both the linear and nonlinear relations of the GH values. The Pharmacia polyclonal IRMA (p-IRMA) and the DELFIA monoclonal time-resolved ...
متن کاملLong-term results of GH therapy in GH-deficient children treated before 1 year of age.
OBJECTIVES To evaluate the long-term effects of GH therapy in early diagnosed GH-deficient patients treated before 1 year of age. STUDY DESIGN We studied all 59 patients (33 males) recorded by Association France-Hypophyse and treated with GH (0.50+/-0.15 IU/kg (S.D.) per week) before 1 year of age. Clinical presentation and growth parameters under GH treatment were analyzed. RESULTS Neonata...
متن کاملSerum leptin levels during recombinant human GH therapy in adults with GH deficiency.
OBJECTIVE Recent studies suggest an involvement of the obese (OB) gene and its product leptin in the regulation of body fat. Since adults with growth hormone deficiency (GHD) have a high body fat mass which can be normalized with recombinant human (rh) GH therapy, we investigated whether GH influences serum leptin directly or indirectly via its lipolytic effect. DESIGN Fourteen adults with GH...
متن کاملInability of heterologous growth hormone (GH) to regulate GH binding protein in GH-transgenic swine.
Transgenic pigs expressing bovine, ovine, or human growth hormone (GH) structural genes fused to mouse metallothionein-I (mMT-bGH), ovine MT (oMT-oGH), or mouse transferrin (mTf-hGH) promoters were used to study the effects of GH on the regulation of serum GH-binding protein (GHBP). In the 14 transgenic pigs studied, circulating concentrations of heterologous GH ranged from 15 to 2,750 ng/mL. U...
متن کاملImmune growth hormone (GH): localization of GH and GH mRNA in the bursa of Fabricius.
Expression of growth hormone (GH) and GH receptor (GHR) genes in the bursa of Fabricius of chickens suggests that it is an autocrine/paracrine site of GH production and action. The cellular localization of GH and GH mRNA within the bursa was the focus of this study. GH mRNA was expressed mainly in the cortex, comprised of lymphocyte progenitor cells, but was lacking in the medulla where lymphoc...
