인슐린은 저항성은 고인슐린혈증, 당불내성, 혈청 지질대사 이상, 고혈압 등을 발생시켜 이들 대사장애를 모두 일컬어 X-증후군, 일반적으로 대사증후군으로 부른다. 당뇨병의 합병증을 예방하거나 치료시 반드시 고혈압은 치료해야 한다.

Congenital metabolic disorders are rare inherited disorders resulting from a defect in biochemical and metabolic pathways affecting proteins, fats, carbohydrates metabolism or impaired organelle function. Depending on the abnormality of biochemical metabolism, various precursors and their abnormal metabolites can accumulate in the body and the final products which are critical in normal physiology can be deficient, resulting in disease. Congenital metabolic disorders present complicated medical conditions involving several human organ systems, including nervous system, eyes, liver, and kidneys. Various proteins and lipids are involved in the development and homeostasis of the skin, so many congenital metabolic disorders present abnormal changes in skin and hair. In this review, congenital metabolic diseases related to amino acid and lipid metabolism accompanying skin abnormalities will be discussed.

The aim of this study was evaluated the effect of biological activity of Hijikia fusiforme (HF). To investigate the effects of biological activity of HF ethanol extracts, Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented ethanol extracts of HF at 50 mg/kg bw/day (OVX-HF50), ovariectomized rats supplemented ethanol extracts of HF at 200 mg/kg bw/day (OVX-HF200). HF ethanol extracts were orally supplemented at the level of 1 mL per day. The body weight gain, food intake and food efficiency ratio were not significantly different between groups. Although total-cholesterol and triglyceride were increased in the ovariectomized control, supplementation with the HF extracts decreased the levels. And HDL-cholesterol levels were significantly increased after supplementation with the HF extracts $(p<0.05)$. According to these results, we could known the effects biological activity of Hijikia fusiforme. Consequently, we expect the effects of Hijikia fusiforme extract on cardiovascular diseases aging coming from postmenopausal.

The purpose of this study was to investigate the effects of regular walking exercise on health-related parameters in the elderly with chronic diseases - apoplexy, overweight, impaired fasting glucose, and overweight + impaired fasting glucose. A total of 85 subjects, 27, 17, 21 and 20 in apoplexy (A), overweight (O), impaired fasting glucose (IFG), overweight + impaired fasting glucose group (O_IFG), respectively, completed a 12-week walking exercise. The health-related parameters were measured before and at the completion of the exercise program including anthropometric measurements, functional physical fitness levels, blood pressure, fasting glucose, blood lipid profiles and chronic inflammatory markers (CRPs). Significant improvements in body weight, BMI, %body fat, blood pressure, all blood lipid measurements and all measured physical fitness items were shown in A; those in %body fat, TC, HDL-C and LDL-C in O; those in body weight, BMI, %body fat, fasting glucose, TC, TG and HDL-C in IFG; and those in body weight, HDL-C and LDL-C in O_IFG (p<0.05). The results of the present study demonstrated that a 12-week walking exercise brought positive effects on body weight, bloody lipid profiles, fasting glucose and functional physical fitness levels in the elderly with chronic diseases. In conclusion, this study suggested that walking regularly is very effective in lowering the risks of developing chronic diseases.

Purpose : This study investigated the clinical significance of AN in children and adolescents with obesity induced metabolic complications. Methods : Forty-nine patients who had obesity induced metabolic complications were participated in this cross-sectional study. Obesity induced metabolic complications are as follows: hypertension, dyslipidemia, impaired fasting glucose (IFG), impaired glucose tolerance (IGT), nonalcoholic steatohepatitis (NASH), homeostasis model assessment of insulin resistance (HOMA-IR)>3.16. Clinical characteristics, such as, age, percentage-weight-for-height (PWH), pubertal status, blood pressure (BP), fasting plasma insulin level, fasting and post-oral glucose tolerance test 2-hour glucose levels, liver function test, lipid profile, HOMA-IR were compared according to the presence of AN. Results : Sixty-five percent of patients had AN, 57.1% NASH, 57.1% dyslipidemia, 55.1% hypertension, 46.9% IFG, 24.5% HOMA-IR>3.16 and 16.2% IGT. The patients who were moderately to severely obese with AN had higher incidence of IGT and HOMA-IR>3.16. The patients with AN had significantly higher diastolic BP ($79.4{\pm}6.9$ vs $75.4{\pm}5.6mmHg$), fasting levels of plasma insulin ($10.6{\pm}6.0$ vs $6.2{\pm}5.4{\mu}IU/mL$), HOMA-IR index ($2.6{\pm}1.4$ vs $1.4{\pm}1.3$) and PWH ($42.4{\pm}13.0$ vs $34.3{\pm}1.8%$). The increasing tendency for the presence of AN was significantly related to the cumulative number of obesity induced metabolic complications. Binary logistic regression analysis revealed that the presence of AN was significantly associated with fasting plasma insulin level, PWH and IFG. Conclusion : AN could be useful as a clinical surrogate of obesity induced metabolic complications.

Hepatic endoplasmic reticulum (ER) stress contributes to the development of steatosis and insulin resistance. The components of unfolded protein response (UPR) regulate lipid metabolism. Recent studies have reported an association between ER stress and aberrant cellular lipid control; moreover, research has confirmed the involvement of sterol regulatory element-binding proteins (SREBPs)-the central regulators of lipid metabolism-in the process. However, the exact role of SREBPs in controlling lipid metabolism during ER stress and its contribution to fatty liver disease remain unknown. Here, we show that SREBP-1c deficiency protects against ER stress-induced hepatic steatosis in mice by regulating UPR, inflammation, and fatty acid oxidation. SREBP-1c directly regulated inositol-requiring kinase 1α (IRE1α) expression and mediated ER stress-induced tumor necrosis factor-α activation, leading to a reduction in expression of peroxisome proliferator-activated receptor γ coactivator 1-α and subsequent impairment of fatty acid oxidation. However, the genetic ablation of SREBP-1c prevented these events, alleviating hepatic inflammation and steatosis. Although the mechanism by which SREBP-1c deficiency prevents ER stress-induced inflammatory signaling remains to be elucidated, alteration of the IRE1α signal in SREBP-1c-depleted Kupffer cells might be involved in the signaling. Overall, the results suggest that SREBP-1c plays a crucial role in the regulation of UPR and inflammation in ER stress-induced hepatic steatosis.

The aim of this study is to evaluate the effect of Porphyra tenera (PT) extract on serum lipids content in ovariectomized rats. From day 3 until 42 after the ovariectomy, Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovarjectomized rats supplemented with PT at 50 mg/kg bw/day (OVX-PT50), 200 mg/kg bw/day (OVX-PT200). The PT ethanol extract were orally administrated at 1 m1 per day. Body weight gain, food intake and food efficiency ratio were not significantly different between groups. Although total-cholesterol was increased in OVX-control, supplementation with the PT decreased the level of cholesterol in serum. Especially, it was significantly decreased in OVX-PI50 (p＜0.05). Triglyceride was significantly decreased to almost all of groups supplemented with PT (p＜0.05). The levels of HDL-cholesterol was higher in PT extract group than OVX-control. These results suggest that supplementation with the PT extract positively influenced on lipid concentration in serum. Consequently, we expect that PT extract decrease risk of cardiovascular diseases by postmenopausal.
