[์˜๋ฌธ] In a placebo controlled trial, we studied the effects of six months treatment of recombinant human growth hormone (rhGH) in 28 adults with GH deficiency. The patients had acquired GH deficiency due to pituitary tumors (13 cases), Sheehan's syndrome (13 cases), and head trauma (2 cases). They were random1y divided into three groups. The group 1(10 cases, M:F = 5:5) received 0.06 U of rhGH per kilogram of body weight subcutaneously three times a week at bed time, the group 2(9 cases, M:F = 4:5) received saute amount of rhGH daily, and the group 3(9 cases, M:F = 4:5) received placebo. In al1 three groups the total body weight did not change, whereas mean lean body mass significantly increased and adipose tissue mass decreased in rhGH treatment groups. The plasma glucose and glycated hemoglobin levels were not increased during rhGH treatment. The bone mineral densities of spines and femurs were net changed. According to computed tomography on two levels (umbilicus and mid-thigh), the mean mid-thigh muscle mass was significantly increased in group 1, while visceral fat mass significantly decreased in group 2. In groups 1 and 2, rhGH slightly increased exercise maximum oxygen uptake, significantly increased exercise rate-pressure product, hand grip strength and back lift strength after rhGH. treatment, but the placebo group had not any change. These results suggest that rhGH hart various potentially beneficial effects in GH-deficient adults, especially in changing body composition and increasing exercise capacity.restrictio

[์˜๋ฌธ] It is well known that growth hormone(GH) stimulates growth, but studies on metabolic effects of growth hormone have recently been increasing. The purpose of this study was to clarify the effects of growth hormone treatment on body composition, glucose and bone metabolism in hypophysectomized growth hormone-deficient rats. The 20-week-old male Sprague-Bawler rats were hypophysectomized and replaced with cortisol and thyroxine for S weeks, then administered with recombinant human growth hormone for 2weeks. Group 1 consisted of intact controls(n= 15), while group 2 consisted of hypophysectomized controls(n= 12), and group 3 consisted of those with GH treatment(n= 13). The body weights, body composition, blood glucose levels, plasma insulin-like growth factor-I(IGF-I) levels, IGF-I mRNA expression in liver, euglycemic hyperinsulinemic clamp test, glycogen synthase activities in gastrocnemius muscle, and bone mineral densities were measured before and after growth hormone treatment. Both plasma IGF-I levels and liver IGF-I mRNA expression in GH-treated group increased to intact control group levels after 2 weeks of GH treatment. There were significant changes in body composition after the treatment (fat mass significantly decreased and lean body mass significantly increased). There were no changes in glucose metabolism in peripheral tissue after 2weeks of GH treatment. Bone mineral densites significantly decreased in hypophysectomized rats(group 2 and 3) compared with intact control group. Two weeks of GH treatment did not increase bone mineral density. In conclusion, human GH treatment(4IU/kg/day) in adult hypophysectomized GH-deficient rats changed the body composition, but did not alter the glucose metabolism in peripheral tissue and the bone mineral density.restrictio

In the case of liquid jets impinging rotating surfaces, however, fingers form at a critical radius. These fingers act as drainage ducts, eventually causing the liquid film to reach a constant radius. Here we experimentally deduce that substrate wettability, angular velocity, fluid properties, and flow rate to affect the film's radius. We further construct a theoretical model to predict the steady-state film radius as function of the mentioned parameters and find that our predictions are in well agreement with experimental observations.๊ตญ๋ฌธ ์ดˆ๋ก i ๋ชฉ์ฐจ ii List of figures iii List of tables iv ๊ธฐํ˜ธ ์„ค๋ช… v 1. ์„œ๋ก  1 2. ์‹คํ—˜ ์žฅ์น˜ ๋ฐ ์‹คํ—˜ ๋ฐฉ๋ฒ• 3 2.1 ์‹คํ—˜ ์žฅ์น˜ 3 2.2 ์‹คํ—˜ ๋ฐฉ๋ฒ• 5 3. ์‹คํ—˜ ๊ฒฐ๊ณผ 11 4. ์ตœ์ข… ์•ก๋ง‰ ๋ฐ˜์ง€๋ฆ„ ์ด๋ก  ๋ชจ๋ธ๋ง 16 5.
