Effects of Low-Dose Recombinant Human Growth Hormone on Bone Densities of Radius, Tibia and 4th Lumbar Vertebrae in Rabbits
Objective- To determine the effects of growth hormone (GH) therapy on bone density in controlled conditions in healthy adult rabbits. Design- Experimental in vivo study. Animal- 20 healthy, adult New Zealand White rabbits. Procedures- The rabbits were divided into 2 groups; receiving Human GH (0.006 mg/kg/d) and controls; receiving placebo for 3 months. The density of radius and tibia was m...

CONSTRUCTION OF RECOMBINANT PLASMIDS FOR PERIPLASMIC EXPRESSION OF HUMAN GROWTH HORMONE IN ESCHERICHIA COLI UNDER T7 AND LAC PROMOTERS
In order to study the periplasmic expression of human growth hormone (hGH) in Escherichia coli, the related cDNA was inserted in two expression plasmids carrying pelB signal peptide, one with lac bacterial promoter and the other with a bacteriophage T7-based promoter. The recombinant plasmids were moved to TG1 and BL21 strains of E. coli, respectively. To induce the expression systems, IPTG and...
متن کاملMetal ions binding study on human growth hormone by isothermal titration calorimetric method
The interaction of hGH with some metal ions ( ) at 27°C in NaC1 solution, 50 mM was studied using Isothermal titration calorimetry. There is a set of three identical and non-interacting binding sites for binding of all these metal ions, expect . The intrinsic association equilibrium constants () are not very different for and , and also their molar enthalpies of binding (KJ/mol for and KJ/mo...
