  • Normal growth and development is of prime concern during childhood. The treatment of children with growth hormone deficiency has been revolutionized by growth hormone therapy. An improved height outcome with a final height within the target height range has been achieved. However, close follow-up with regular clinical and laboratory monitoring is essential for achieving the desirable height outcome. The theoretical unlimited supply of growth hormone has led to its wide spread use in a variety of disorders other than a growth hormone deficiency. Initially used in children with Turner syndrome, growth hormone is now used to treat chronic renal failure, an idiopathic short stature and intrauterine growth restrictions in addition to a wide array of newly emerging indications. This review summarizes the basics for a proper growth assessment, the differentiation of normal and abnormal growth causes of a short stature, and the indications for growth hormone treatment.

  • Heat stress is known to affect physiological systems in goats. This study investigated changes in nutrient digestibility, behavior and growth hormone secretion among goats in a hot environment (H; 35${\pm}$ 1.2$^{\circ}C$, [RH] 80${\pm}$7.2%, 13 d), and in a thermoneutral environment (T; 20${\pm}$0.6$^{\circ}C$, [RH] 80${\pm}$3.4%, 20 d), and accompanied by the same restricted diet as provided in the hot environment. The following results were obtained: rectal temperature and water intake were higher in the H treatment than in the T treatment or TR treatment, while hay consumption was lower. CP, NDF and ADF digestibility was highest in H treatment. Time spent eating in the H treatment was also the highest, followed in order by T treatment and TR treatment. Ruminating time was lower in H treatment than in T treatment or TR treatment, and reposing time was highest in the TR treatment. Growth hormone concentrations in T increased 4.5 h after feeding. In H, growth hormone concentrations increased 0.5 h after feeding. However, growth hormone concentrations were not changed following TR feeding. In conclusion, heat exposure in goats decreased feed intake, but increased digestibility. However, when goats in a thermoneutral environment received the same restricted feeding as they received in the hot environment, digestibility increased. Between the H treatment and TR treatment, the changes in digestibility were accomplished by coordinate changes in hormone secretion in order to maintain body homeostasis. To maintain energy balance under a hot temperature or a restricted feeding condition, goats may control their metabolism by changing growth hormone release.

  • Prader-Willi syndrome is a complicated genetic disorder caused by a mutation on chromosome 15q11-13. The disease results in morbid obesity due to hyperphagia, growth disturbance, multiple endocrine problems from hypopituitarism, developmental delay, and cognitive or behavioral problems. Recombinant human growth hormone has been used to improve body composition and muscle mass, which plays a main role in treating patients with Prader-Willi syndrome. We describe previous studies showing the efficacy and safety of growth hormone treatment in children with Prader-Willi syndrome and provide treatment guidelines. Growth hormone therapy could be beneficial for children with Prader-Willi syndrome and improve their quality of life.

  • Recombinant growth hormone (GH) is an effective treatment for short children who are born small for gestational age (SGA). Short children born SGA who fail to demonstrate catch-up growth by 2-4 years of age are candidates for GH treatment initiated to achieve catch-up growth to a normal height in early childhood, maintain a normal height gain throughout childhood, and achieve an adult height within the normal target range. GH treatment at a dose of $35-70{\mu}g/kg/day$ should be considered for those with very marked growth retardation, as these patients require rapid catch-up growth. Factors associated with response to GH treatment during the initial 2-3 years of therapy include age and height standard deviation scores at the start of therapy, midparental height, and GH dose. Adverse events due to GH treatment are no more common in the SGA population than in other conditions treated with GH. Early surveillance in growth clinics is strongly recommended for children born SGA who have not caught up. Although high dose of up to 0.067 mg/kg/day are relatively safe for short children with growth failure, clinicians need to remain aware of long-term mortality and morbidity after GH treatment.

  • The growth effects of newly developed recombinant human growth hormone (rHGH), were compared with those of Biotropine. For the effective evaluation, we examined the increasing rate of body weight and the thickness of tibial epiphysis as criteria of growth effects on hypophysectomised female rats treated with varing concentration of rHGH for 4 days. rHGH treated groups showed significant body weight gain which was less evident in Biotropine and vehicle treatment group. In tibial epiphyseal test, rHGH also showed clear effects compared to Biotropine and vehicle treatment group. Above findings indicate that newly developed rHGH has better effects of growth stimulation on female rats than Biotropine does.

  • Since the advent of growth hormone(GH), children with a wide variety of growth disorders have received GH treatment. In GH deficiency(GHD), Turner syndrome, chronic renal failure, children born small for gestational age, Prader-Willi syndrome, and idiopathic short stature, the therapeutic effects and safety profile of GH are reviewed. GH therapy has been clearly shown to improve height velocity and final adult height in a variety of pediatric conditions in which growth is compromised irrespective of GHD. Early initiation and individualization of GH treatment has the potential to normalize childhood growth. The supra-physiological doses of GH have been shown to increase height velocity during childhood and final height in non-GHD conditions. Adverse events during GH therapy are uncommon and often not drug related. However continued surveillance into adult life is crucial, especially in children receiving supra-physiological doses or whose underlying condition increases their risk of adverse effects.

  • Objective: Recent studies have challenged the traditional paradigm that growth hormone receptor (GHR) displays physiological functions only in the cell membrane. It has been demonstrated that GHR localizes to the cell nucleus and still exhibits important physiological roles. The phenomenon of nuclear localization of growth hormone (GH)-induced GHR has previously been described in vitro. However, until recently, whether GH could induce nuclear localization of GHR in vivo was unclear. Methods: In the present study, we used pig as an animal model, and porcine growth hormone (pGH) or saline was injected into the inferior vena cava. We subsequently observed the localization of porcine growth hormone receptor (pGHR) using multiple techniques, including, immunoprecipitation and Western-blotting, indirect immunofluorescence assay and electronmicroscopy. Results: The results showed that pGH could induce nuclear localization of pGHR. Taken together, the results of the present study provided the first demonstration that pGHR was translocated to cell nuclei under pGH stimulation in vivo. Conclusion: Nuclear localization of pGHR induced by the in vivo pGH treatment suggests new functions and/or novel roles of nuclear pGHR, which deserve further study.

  • Growth hormone (GH) treatment has been increasingly widely used for children with GH deficiencies as the survival rate of pediatric patients with malignancies has increased. Both GH and insulin-like growth factor-I have mitogenic and antiapoptotic activity, prompting concern that GH treatment may be associated with tumor development. In this review, the authors examined the relationship between GH treatment and cancer risk in terms of de novo malignancy, recurrence, and secondary neoplasm. Although the results from numerous studies were not entirely consistent, this review of various clinical and epidemiological studies demonstrated that there is no clear evidence of a causal relationship between GH treatment and tumor development. Nonetheless, a small number of studies reported that childhood cancer survivors who receive GH treatment have a small increased risk of developing de novo cancer and secondary malignant neoplasm. Therefore, regular follow-ups and careful examination for development of cancer should be required in children who receive GH treatment. Continued surveillance for an extended period is essential for monitoring long-term safety.

  • Turner syndrome (TS) is a genetic disorder in phenotypic females that has characteristic physical features and presents as partial or complete absence of the second sex chromosome. Growth hormone deficiency (GHD) is a condition caused by insufficient release of growth hormone from the pituitary gland. The concomitant occurrence of TS and GHD is rare and has not yet been reported in Korea. Here we report 2 cases of TS and GHD. In case 1, GHD was initially diagnosed. Karyotyping was performed because of the presence of the typical phenotype and poor response to growth hormone therapy, which revealed 45,X/45,X+mar. The patient showed increased growth velocity after the growth hormone dose was increased. In case 2, a growth hormone provocation test and chromosomal analysis were performed simultaneously because of decreased growth velocity and the typical TS phenotype, which showed GHD and a mosaic karyotype of 45,X/46,XX. The patient showed spontaneous pubertal development. In female patients with short stature, it is important to perform a throughout physical examination and test for hormonal and chromosomal abnormalities because diagnostic accuracy is important for treatment and prognosis.

  • Purpose: The study was attempted to provide basic materials for development of nursing-intervention programs by examining effects of growth hormone therapy on the quality of life, depression and self-esteem. Method: A survey was conducted for 31 adult outpatients as experimental group who have received growth hormone therapy more than 6 months and for 29 adults as control group who have not. A scale developed by Hilditch was used to measure their quality of life and also, the Zung's Self-rating Depression Scale and the Rosenberg's Self-esteem Scale were adopted to measure their depression and self-esteem each. Data were analyzed using one-way and two-way ANOVA Result: 1) there were differences between the two groups in the overall measurement of the quality of life. the growth hormone therapy group was higher in sub-factors 2) There were clear-cut differences between the two groups in depression, so that the control group marked higher score in the measurement of depression. 3) Self-esteem was not identical across the two groups, so that it was more higher for the growth hormone treatment group. Conclusion: Those findings suggest that development of education programs related to growth hormone and nursing-intervention is promising.
