Background: ALT-P1 (CJ-40002) is a long-acting recombinant growth hormone (GH) fused with NexP, which is a long-acting carrier developed by Alteogen Inc. NexP is a protein engineered recombinant alpha1 antitrypsin with further increased in vivo half-life without a native proteinase inhibitor activity. In non-clinical studies of cynomologus monkeys, the extended half-life of hGH-NexP has been successfully proved without side effects in high dose as 20 mg per kg dose.<p clas...

Background: Premature thelarche (PT) is a benign, non-progressive condition defined as isolated breast development without the activation of the hypothalamic-pituitary axis. While the pathophysiology of PT remains unclear, increased sensitivity to estrogen may cause PT.Objective and hypotheses: The aim of this study was to investigate the association between polymorphisms in the estrogen receptor alpha (ERα) gene and PT in girls.<p class="abstex...

Background: Congenital hypothyroidism (CH) is the one of the most common preventable cause of mental retardation. Earlier and proper treatment is associated with better intellectual outcomes.Objective and hypotheses: The aim of the present study was to evaluate intellectual outcome of children with diagnosed congenital hypothyroidism (CH) and early onset treatment.Method: We retrospectively reviewed the medical record of 43 childre...

Context: It has recently been shown that mutations of MKRN3, the gene encoding makorin RING-finger protein 3, lead to central precocious puberty (CPP). The aim of this study was to investigate mutations of the MKRN3 gene in Korean girls with CPP.Methods: Two hundred and sixty Korean girls with idiopathic CPP were included in this study. Auxological and endocrine parameters were measured. The entire MKRN3 gene was directly seque...

Objective: Obesity is associated with bone age (BA) advancement of unclear etiology. In animal study, insulin may directly modulate skeletal growth. Our objective was to investigate the association with BA maturation and insulin levels in children with overweight and obesity.Methods: In this cross-sectional study of 42 prepubertal children, anthropometric data and hormonal values during oral glucose tolerance test were measured. Subjects were divided int...

Background: Hyperinsulinism/hyperammonemia (HI/HA) syndrome is a form of congenital hyperinsulinism (CHI) caused by a mutation in the GLUD1 gene. It is characterized by hyperinsulinemic hypoglycemia accompanying hyperammonemia.Objective and hypotheses: We report HI/HA syndrome with a 4-month-old male who hypoglycemic seizure.Method: A 4-month-old male infant presented with seizure caused by fasting-induced hypoglycemia. At the time...

Background: GnRH agonist (GnRHa) are able to modify natural course of Central Precocious Puberty (CPP) in girls.Objective and hypotheses: We evaluated the etiology and the effect of GnRHa in Korean CPP boys.Method: Total 29 boys diagnosed for CPP from 2007 to 2012 were included in Ajou University Medical Center. Sellar MRI was performed in 26 of 29 patients (89.7%). CPP was diagnosed on the basis of i) onset evidence of testicular ...

Background: Hypoxia represents a main risk factor for acquired brain injuries and neurological disabilities in premature and full-term infants. Stabilization of hypoxia-inducible transcription factors (HIF) is one of the most important adaptive mechanism modulating the degree of hypoxic-ischemic brain lesions due to cellular adaptation to reduced oxygen concentrations. Additionally, neuro-protective effects of GH and GH-induced neurotrophic factors are evident as shown by prev...

Objective and hypotheses: The purpose was to get the basic data of optimum serum concentration of oestrogen in pubertal growth spurt, minimising the decrease of bone mineral density or acceleration of epiphyseal closure of long bones.Method: i). Fifteen female S.D. rats (4-week aged) were ovariectomised to inhibit their endogenous oestrogen effect and randomly divided into three groups. After 1 week, the group 1 were injected subcutaneousl...

Background: Acquired QT prolongation can be caused by electrolyte abnormality, myocarditis, cerebrovascular disease, drug intoxication and hormonal disorders such as hypopituitarism, hypothyroidism, and adrenal insufficiency.Case presentation: We describe a 14-year-old boy with hypopituitarism after trans-sphenoidal surgery (TSS) due to suprasellar mass who manifested bradycardia and QT prolongation on electrocardiogram. This subject complained of blurre...
