The Effect of Testosterone on the Response of Grow Hormone Secretion in Cultured Rat Pituitary Cells
Ho Seong Kim, Duk Hi Kim, Deok Bae Park
Clin Exp Pediatr. 1993;36(11):1578-1582.   Published online November 15, 1993
The effects of testosterone on the pituitary growth hormone(GH) response directly and to hypothalamic growth hormone-releasing hormone(GHRH) were evaluated in vitro using a male pituitary cell monolayer culture system. Wistar male rats were gonadectomized at 22 days of age, and 21 days later their anterior pituitaries were removed and trypsinized for cell dispersion. Testosterone 0.01, 1.0, 10.0nM was added to...
The Effects of Testosterone on the Pituitary Growth Hormone Secretion
Ho Seong Kim, Duk Hi Kim, Kyung Za Ryu, Chang Mee Kim, Deok Bae Park
Clin Exp Pediatr. 1992;35(2):174-181.   Published online February 15, 1992
The effects of testosterone on growth hormone secretion and somatic growth have been reported in several previous studies. In order to investigate the role of testosterone in growth hormone secretion, we have studied the effect of testosterone on somatic growth, basal growth hormone concentration, and growth hormone response to growth hormone-releasing hormone (GHRH) in orchiectomized rats. In experiment 1, four groups...
Effects of sex hormone on secretion of growth hormone.
Bo Young Lee, Duk Hi Kim
Clin Exp Pediatr. 1991;34(12):1621-1628.   Published online December 31, 1991
Sex honnone had been thought to influence in the serum level of growth honnone (GH) since 1944 year. After it became known that the exogenous administration of sex honnone to growth-retarded children increase serum GH level, sex honnone-especially testosterone-was thought to induce GH release. Testosterone is thought to act on the hypothalamo-pituitary axis to stimulate GH secretion and estradi이 is also thought...
A Study on the Correlation of the Stages of Pubertal Development with Serum Levels of FSH, LH, Testosterone and Estradiol in Normal Children.
Sang Kee Park, Chang Soo Ra
Clin Exp Pediatr. 1987;30(5):536-551.   Published online May 31, 1987
Puberty is the period, during which many changes of somatic growth, maturation of gonads and development of secondary sex characteristics occur so that reproduction of the species can be maintained. Pubertal growth and development is unique. So, a working of its onset, sequence, and charateristics are prerequisite to the provision of effective comprehensive medical care to the adolescent. Author studied the stages of pubertal...
A Study on Hormonal Change of Lh, FSH, and Testosterone and Testicular Volumes in Pubertal Mal Children.
Heung Dong Kim, Duk Hi Kim, Ki Keun Oh
Clin Exp Pediatr. 1986;29(9):979-987.   Published online September 30, 1986
The mechanism involved in pubertal changes has not been clearly demonstrated, but evidence has been accumulated that hormonal changes are responsible for this pubertal changes. We studied the height, weight, testicular volume, bone age, LH, FSH, and testosterone, "by Tanner stage of pubic hair development in 134 pubertal male children with no previous endocrine disease, who admitted at Yonsei University Medical...
