Sleep plays an important role in maintaining overall human health. There is increasing interest regarding the impact of sleep related disorders on metabolic diseases. Obstructive sleep apnea (OSA) is a common health problem, and in the last decade, the emergence of increasing obesity rates has further led to a remarkable increase in the prevalence of OSA, along with more prominent metabolic diseases. Obesity is the strongest risk factor for OSA. However, OSA is also known to cause obesity, suggesting an interaction between OSA and obesity. Although the underlying mechanisms leading to OSA-induced metabolic diseases are probably multi-factorial and are yet to be fully elucidated, the activation of inflammation and oxidative stress and the dysregulation of appetite-regulating hormones have emerged as important pathophysiological components of metabolic dysfunction and obesity observed in patients with OSA. Here, we will review the current state of research regarding the association of OSA with metabolic diseases and the possible pathophysiological mechanisms by which OSA could lead to such diseases. This will enhance our understanding of the potential interactions between OSA and obesity and between OSA and metabolic dysfunction.

영양은 신진대사 기능을 조절하고 신체 및 정신 활동으로 소모된 부분을 보충하여 생명체가 존속하고 활동하는데 반드시 필요한 양분이다. 또한 영양소는 대사작용에 이용되는 기본 물질이며 탄수화물, 지방, 무기질, 비타민, 수분 등의 6가지가 있다. 신체의 정상적인 기능과 효율적인 작용에 영향을 미치는 영양소는 그 작용에 따라 주영양소인 근 수축에 필요한 에너지를 공급하는 열량소, 부영양소인 생리적 작용을 조절하여 질병을 예방하는 조절소, 그리고 신체 기관과 조직을 구성하는 구성소로 구성된다.(중략)

영양소로서의 물의 중요성에 대해서는 앞에서 이미 충분히 강조한 바 있다. 물은 동물체의 주성분일 뿐아니라 며칠간 사료의 급여를 중단했을 때 가축이 받는 스트레스 보다 물의 급여를 중단했을 때 받는 스트레스가 훨씬 크다는 사실로 보더라도 물을 제외한 모든 영양소를 합한 것보다 물이 더 중요하다는 사실을 말해준다. 오늘은 물의 물리적 및 화학적 성질을 고찰하고 닭의 체내에서 물의 생리적 기능 및 물의 체내 대사에 대해서 알아보기로 한다.

간의 약물대사는 흡수된 외인성물질의 배설을 위한 중추적인 역할을 수행하면 이 반응은 일상대사와 이상대사효소로 구성된 약물대사효소계에 의해 매개된다. 약물대사효소의 발현과 활성은 외인성물질의 노출에 의해 유도되거나 억제되며 이 결과는 약물상호작용을 발생시키는 주요한 원인이다. 또한 당뇨, 비만, 영양실조, 음주, 염증반응 등의 병적인 생리상태는 간에서 약물대사효소의 발현과 활성을 조절하는 것으로 보고되고 있다. 이러한 변동은 치료약물 또는 환경오염물질에 대한 인체의 반응성에 영향을 미치며 결과적으로 예측하지 못한 부작용이나 독성을 발생시킬 수 있다. 본 논문에서는 당뇨병에서 약물대사효소의 발현변화를 정리하였다.

This study conducted the following experiment to examine change of biophysical and physical fitness function on combined exercise program in 20' female university students with obesity according to heights of insole. Obesity related biophysical function was measured by basal metabolism and percent body fat(% Fat) and health related physical fitness was measured by isokinetic strength of quadriceps femoris muscle, muscular endurance, flexibility and power on comparative analysis of pre, post exercise and each groups(0cm, 5cm, 9cm) in 36 female university students with obesity subject according to heights of insole. These result lead us to the conclusion that each group were statistically improved at isokinetic muscular strength of quadriceps femoris muscle and basal metabolism, but 5cm group compared with 0cm and 9cm group was more significant improvement. Consequently, combination exercise applying appropriate heights of insole would be lead to positive increment of muscular strength and basal metabolism.

This study was conducted to investigate the negative physiological impact of saline to roadside trees and to assess the physio-biochemical tolerant characters of woody plants against salinity. Two-year-old Zelkova serrata seedlings treated with 0, 3, 14, 56, and 112 mM NaCl were measured for root collar diameter and cambial electric resistance (as an indication of vitality) and analyzed for carbohydrate and mineral content in the leaves. Z. serrata was affected by NaCl treatments. The vitality of Z. serrata decreased with an increase in NaCl concentration, and the NaCl treatment resulted in nutrient imbalance shown by changes of ion concentration in the tissues. However, relative growth rate for diameter and carbohydrate metabolism in the leaves were not greatly influenced by NaCl treatment. Short-term treatment or low NaCl concentration may not have an observed impact on growth. Nevertheless, roadside trees exposed to saline during the long term would likely show negative effects for growth performance from altered ion concentrations.

The development of blood ionic changes could be precipitated in acid-base disorder and subsequent treatment. As technology for detecting circulating ionized $Mg^{2+}$ (the most interesting form with respect to physiological and biological properties) is now available in veterinary clinical medicine. This present study investigated the changes of whole blood ionized $Mg^{2+}$ correlated with acute metabolic and respiratory alkalosis in rodent model. Metabolic alkalosis was induced by intravenous infusion with $NaHCO_3$ and mechanical hyperventilation was applied for respiratory alkalosis. We founded that the blood ionized $Mg^{2+}$ could be reversibly decreased by the $NaHCO_3$-induced acute metabolic alkalosis but irreversibly increased by the mechanical hyperventilation-induced respiratory acidosis and respiratory acidosis. We suggested that the potential change in blood suggested that the potential change in blood ionized $Mg^{2+}$ should be counted in treatment of acid-base disorders.

In order to elucidate growth characteristics, physiological responses and leaf color changes of leaf-variegated Arundinaria munsuensis and Carex ciliato-marginata for variegata, These experiments were performed under four different light ragimes control(full sun), 40%, 70% and 85%. Plant height and leaf area became promoted as shading level increases in leaf-variegated Arundinaria munsuensis. Photosynthetic effect was the highest in 85% shading of the full sun. Thus, this plant could be growing in the deep shade condition. Plant growth and the leaf color changes were most obviously shown in the 40% shading level. In the Carex ciliatomarginata for. variegata growth status was the best and green or strong greenish yellow leaf color turned out to be much clearer in the 40% shading treatment. And photosynthetic activity was enhanced as the light intensity decreases.

The transition from pregnancy to lactation, commonly referred to as the "transition period" is characterized by dramatic changes in metabolic processes and their regulation in order to prepare the dairy cow for parturition and lactogenesis. An important adaptation to lactation is the increase in gluconeogenesis by the liver to meet the tremendous increase in demand of glucose for lactose synthesis, and the accumulation of lipid in adipose tissue during pregnancy, its mobilization that begins prior to lactation and the dramatic increase in plasma NEFA concentration early lactation. Epinephrine and insulin, the homeostatic regulators of metabolism are responsible for the adaptations of lipid and carbohydrate metabolism in support of milk production along with mobilization of body fat to meet overall energy demands because dry matter intake is insufficient to meet these demands during early lactation.
