Synergistic polysaccharide-polysaccharide interactions are attractive commercially and enjoy widespread technological exploitation (Cairns et al., 1987). Expensive polymers may be replaced by a cheaper mixture. Xanthan/LBG solution was prepared by adding the gum into hot water and further heating to 80℃ for about 30 min with continuous stirring to ensure complete solubility and to obtain a clear homogenous solution. The storage modulus(G`) and the yield stress of solutions were increased with increasing LBG ratio, which was mostly noticed between LBG ratio 0.5∼0.75. On the other hand shear thinning effect was shows at high shear on LBG ratio 0.25. Elastic modulus was increased with increasing LBG more than two times and it was enhancing suspending properties on emulsion. Since the rheological properties describe the fundamental information about the cosmetic, these results may be of help to the design of new feeling cosmetic emulsion.

본 연구에서는 KI-188 칼슘과 KI-180 조성물이 성장발육에 미치는 효과를 조사하였다. 시험기간중 KI-188 칼슘과 KI-180 식이군이 대조군 보다 성장률과 평균 식이섭취량은 증가하였다. 체장은 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 평균 3.55 mm 더 길었고, 등뼈길이는 KI-180 식이군이 대조군 보다 통계적인 차이는 없었지만 0.5 mm 더 길었다. 대퇴골 무게는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 무거웠으며, 대퇴골길이는 대조군에 비해 각각 평균 0.89, 1.09 mm 더 길었다. 혈당, 총콜레스테롤 및 중성지방 농도는 차이가 없었고, 칼슘농도는 KI-188 칼슘과 KI-180 식이군 보다 대조군이 유의하게 높았다. 백혈구와 혈소판수는 차이가 없었고, 적혈구, 혈색소 및 헤마토크릿치는 대조군이 KI-188 칼슘과 KI-180 식이군 보다 통계적으로 높았다. ALP활성은 KI-180 식이군이 대조군 보다 통계적으로 높았고, osteocalcin농도는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 유의하게 높았다. 혈청 testosterone 농도는 KI-188 칼슘과 KI-180 식이군과 대조군 간에 차이가 없었다. IGF-1과 IGFBP-3 농도는 KI-180 조성물이 대조군 보다 각각 20%, 11% 정도 유의하게 더 높았다. 이상의 결과를 검토할 때 KI-188 칼슘과 KI-180 조성물은 어린쥐의 성장과 골격의 발달을 촉진시키고, 성장호르몬의 분비능을 양적으로 유도하여 전반적인 성장발육에 유효한 작용이 있는 것으로 사료된다. Herbs have active components that promote the growth rate of both animals and human. The KI-180 and KI-188 calcium food formulae contain Acanthopanacis cortex, Bombysis corpus and hoelen, seaweed calcium, chlorella extract, spirulina, colostrum powder, and other natural and functional components. We evaluated the growth-promoting effects of these formulae by analyzing the weight, femur and backbone, alkaline phosphatase, osteocalcin, testosterone, insulin-like growth factor (IGF)-1, and IGF binding protein-3 (IGFBP-3) of growing rats. Growing rats administered with KI-180 and KI-188 calcium showed the increase of body weight, body length, and femur weight and length of growing rats. In addition, administration of KI-180 and KI-188 calcium increased the alkaline phosphatase activity, the levels of osteocalcin and the growth hormones IGF-1 and IGFBP-3 of growing rats. The impact of KI-180 and KI-188 calcium on the physical development of growing rats suggests that the incorporation of these food formulae in the diets of growing children may promote the physical development.
일회성 알코올 섭취 후 가벼운 운동이 순환기능 및 혈관조절인자, 혈중알코올농도 회복에 미치는 영향

The purpose of this study was to compare the effects of acute exercise after alcohol consumption with meal on circulatory function(heart rate, blood pressure), vascular regulatory factor(ET-1,PGI2), alcohol concentration of middle aged sedentary men. Twelve men underwent three experimental condition with randomized, cross-over design at intervals of 7days: alcohol consumption trial with food ingestion(alcohol), a single bout of walking exercise trial immediately after the alcohol ingestion(alcohol+exercise) or placebo(placebo+exercise) ingestion. Walking performed at low intensity(90-1l0beat/min) for 30 min on a motorized treadmill. They drank dry white wine(17%, 7g/kg body weight mixed with orange) or placebo during 30 minutes. Placebo treatment ingested identical amount of fluid not contained alcohol. Venous blood samples were drawn before and 150minutes after alcohol consumption with meal. Heart rate and systolic blood pressure increased significantly 150minutes after alcohol consumption trial. Acute exercise after alcohol consumption alleviate such alcohol induced systolic blood pressure increase. ET-1 and PGI2 did not show any significant change with trial. The values of blood alcohol concentration was significantly lower in the exercise trial at 150minutes than the on1y alcohol consumption trial. The present findings suggest that alcohol consumption resulted hampered circulatory system and exercise after alcohol consumption was more effective for improving circulatory system than non-exercise.

Cardiovascular malformations, such as bicuspid aortic valve and coarctation of the aorta, are more prevalent in patients with Turner syndrome than in the general population. Here, we describe the case of a 35-year-old female with Turner syndrome who was admitted to our hospital with a fever caused by infective endocarditis. Aortic coarctation was diagnosed using computed tomography. The patient was treated with antibiotics and a stent was then implanted. Endovascular therapy using stents is a safe and effective treatment option for aortic coarctation in patients with Turner syndrome. (Korean J Med 2015;89:331-334)
