GH Treatment Prevents Hypoxia-Induced Decrease of GH and IGF1 Plasma Concentrations in Neonatal Mice

Jung Susan , Richter-Kraus Mandy , Brackmann Florian , Dorr Helmut G , Trollmann Regina

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...

Kang Byung Ho , Park Mun Suk , Yang You Jung , Lim Sung Jig , Shim Kye Shik

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...

Jeong Hwalrim , Kwon Eun Byul , Lee Hae Sang , Lim Jung Sub , Hwang Jin Soon

Background: Familial precocious puberty is defined by the existence of more than one affected member either in the proband generation or in the pedigree. Recently, several gene mutation cause familial CPP is elucidated, gain of function mutations in KISS1 and KISS1R, loss of function mutations in the MKRN3, the feature of familial precocious puberty is not fully understood.Objective: To investigate the clinical characteristics of familial precocious pube...

Association between lean mass and metabolic syndrome risk in Korean children and adolescents

Suk Shim Young , Sang Lee Hae , Rim Jeong Hwal , Sub Lim Jung , Soon Hwang Jin

Introduction: Skeletal muscle plays a crucial role in glucose disposal, and studies have shown a positive relationship between muscle mass and insulin sensitivity. However, an elevated lean mass has also been associated with metabolically adverse outcomes. This study aimed to evaluate the association between the risk of metabolic syndrome (MetS) and lean mass using dual-energy X-ray absorptiometry (DXA) in a nationally representative sample from the Korea Nati...
