Jeong Won Shin, Hong Ryang Kil, Jae Hong Yu
Clin Exp Pediatr. 2001;44(8):942-947.   Published online August 15, 2001
Growth hormone receptor gene is expressed in the myocardium and growth hormone(GH) administration has been shown to increase cardiac insulin-like growth factor-I(IGF-1) contents. The cardiac myocyte express IGF-I receptors and IGF-I promotes cardiac hypertrophy. Furthermore GH therapy has been reported to have beneficial effects in the treatment of dilated cardiomyopathy in adults. We have studied the effect of short term...

IGFBP-3 is the major circulating IGFBP and is found primarily as a 150 kDa complex which contains an acid labile subunit(ALS), IGFBP-3, and IGF-I or IGF-II and is considered to be growth hormone(GH) dependent. In this study, we measured serum IGF-I, IGFBP-3 and 150 kDa levels in sera of growth hormone...
The Changes of the Bone Mineral Density in the Girls with Turner Syndrome, using Recombinant Human Growth Hormone
Sei Won Yang
Clin Exp Pediatr. 1996;39(6):839-845.   Published online June 15, 1996
Purpose : Estrogen deficiency causes sexual infantilism in Turner syndrome, which could decrease the bone mineral density(BMD) since birth. This decreased BMD might be contributed by the decreased growth hormone(GH) secretion. To improve the decreased BMD, estrogen therapy is recommended, especially after the pubertal age, but estrogen therpay during childhood can accelerate the epiphyseal fusion, resulting in shorter final height. There is...

Phil-Soo Oh, Ki-Joong Kim, Young-Iee Yu, In-Joon Seol, Jeh-Hoon Shin
Clin Exp Pediatr. 1995;38(10):1394-1403.   Published online October 15, 1995
Purpose : At present, to determine growth hormone(GH) deficiency in short stature, many provocative tests using various pharmacologic agents such as clonodine, L-dopa, insulin should be done. These are not only complicated, but also misleading in some patients. And so, in search of a simple method of detecting GH deficiency that may replace the complicated stimulation test, we measured basal...
