The effects of fruiting body of Cordyceps militaris on the growth, the food intake, the food efficiency ratio, the lipid metabolism, the serum protein level ad enzyme activity in male rats were studied. Sprague-Dawley rats were fed four types of diets for five weeks, respectiely: a control diet, a control diet supplemented with 2%, 3% or 4% fruiting body of Cordyceps militaris(CF) powder. In rats fed 2% or 3% CF diets the body weight gain, the food intake, the concentratons of hepatic triglyceride and serum LDL-cholesterol, the atherogenic index, and the total lipid, total cholesterol, triglyceride and phospholipid in serum were similar to those in rats fed the control diet. Whereas, in 4% CF diet these were significantly decrased. But the all CF diets feeding could not decrease the food efficiency ratio, the weights of liver, pancreas, spleen, kidney and heart, and the concentration of serum HDL-cholesterol. Also, it was shown that the concentrations of glucose, total protein, albumin, urea and creatinine, and the GOT, GPT, LDH, ${\gamma}$-GTP and ALP activities were the same levels in serum of rats of fed all the experimental diets.

BACKGROUND/OBJECTIVES: Inadequate nutrition in infants and young children affects physical growth and neurocognitive development. Therefore, early nutritional intervention is important to promote catch-up growth in young children with faltering growth. The aim of this study was to evaluate the effect of nutritional supplementation with a pediatric concentrated and balanced nutritional supplement formula on promoting growth and improving nutritional status in children with nonorganic faltering growth. SUBJECTS/METHODS: Children aged 12-36 months whose body weight-for-age was < 5^th percentile on the Korean Growth Charts were enrolled. Children born premature or having organic diseases were excluded. Children were instructed to consume 400 mL of formula per day in addition to their regular diet for 6 months. Pediatricians and dietitians educated the parents and examined the subjects every 2 months. Anthropometric parameters were measured at baseline and at 2, 4, and 6 months, and laboratory tests were done at baseline and 6 months. The good consumption group included children who consumed ≥ 60% of the recommended dose of formula. RESULTS: Total 82 children completed the 6-month intervention. At baseline, there were no significant differences in all variables between the good consumption and poor consumption groups. Weight and weight z-scores were significantly improved in the good consumption group compared to the poor consumption group at the end of the intervention (P = 0.009, respectively). The good consumption group showed a significant trend for gaining weight (P < 0.05) and weight z-score (P < 0.05) compared to the poor consumption group during 6 months of formula intake. The concentration of blood urea nitrogen was significantly increased in the good consumption group (P = 0.001). CONCLUSIONS: Nutritional supplementation with a concentrated and balanced pediatric nutritional formula along with dietary education might be an effective approach to promote catch-up growth in children with nonorganic faltering growth.

To compensate for the critical shortage of human organs for allotransplantation, xenotransplantation studies using genetically modified pigs are being performed in Korea. Two types of pigs that are used are ${\alpha}1,3$-galactosyltransferase gene knockout (GalT KO) pigs and GalT KO+hCD46 (human complement regulatory protein) pigs. The present study measured the gestation time, birth weight, daily growth rate, and heart weight of both kinds of transgenic minipigs. The gestation period for both types of pigs was 117~119 days. There was no difference in the body weight of GalT KO (-/+) and GalT KO (-/-) piglets, but GalT KO+hCD46 ($-^{hCD46+}/+$) pigs were significantly heavier at birth than were GalT KO+hCD46 ($-^{hCD46+}/-^{hCD46+}$) pigs. During the first 10 weeks of life, the daily weight gain of GalT KO+hCD46 ($-^{hCD46+}/-^{CD46+}$) piglets, which are considered the optimal type for xenotransplantation, was 0.19 kg. The weight of hearts from GalT KO piglets up to two months of age was affected more by body weight than by age. Transgenic pigs showed no differences in gestation period or reproductive ability compared with normal pigs. These results comprise basic data that may be used in xenotransplantation studies and transgenic animal production in Korea.

Nutrition is an essential component of total adolescent health care. Two important changes occurring during adolescence can cause a crisis in the teenager's nutritional needs. First, growth in height, weight, and body component is greater and more rapid than at any time since infancy. Second, an adolescent's eating habits may change from regular meals prepared at home to irregular meals, skipped meals, and nutrition-poor snacks and fast-food meals. Adolescents have been found to have the highest prevalence of any age group of an unsatisfactory nutritional status. To understand the nutritional requirements of the adolescent, health practitioners should be aware of the intensity and timing of the adolescent growth spurt, the differences in the growth spurt between males and females, and the individual variation in timing of the growth spurt from teenager to teenager.

교정 환자들은 성장과 발육을 하는 개체이므로 교정치료의 시기 선택은 가장 어렵고 중요한 요소이며, 측모두부방사선 사진의 개발에 따라 안면 성장의 양상과 연령 증가에 따른 성장 변화량은 성장 예측 등의 교정적 분야에 유용하게 이용되어왔다. 이에 3세에서 12세까지의 한국인 남여 아동 각 연령군에서의 두개 안면부의 경조직 계측치 평균과 신장, 체중과의 연관성을 파악하고자 하였다. 교정치료를 받은적이 없고, 성장과 발육에 장애가 없는 3세에서 12세까지의 소년 147명과 소녀 106명을 연구대상으로 만 2년간 두부방사선 사진을 채득하여 경조직 분석을 Burstone의 COGS논문에 기초하여 두개저, 상악골과 하악골, 수직 계측, 수평 계측, 상하악 기저골 관계 및 치성 계측의 6개 부분으로 나누어 성장과의 관계 및 키와 몸무게와의 관계를 연구한 바 다음과 같은 결론을 얻었다. 1. 두개저 계측에서 N-Ar(FH), N-Ba(FH)의 최대 성장 증가량은 남녀 모두 체중과 신장의 최대 증가량을 나타내는 연령과 일치한다. 그 외의 항목은 일정 증가 양상을 보이고 있으나 큰 증가를 보이지 않고 있어 두개저의 성장은 초기에 거의 완성됨을 알 수 있었다. 2. Genial angle은 남녀 모두에서 성장과 함께 점차 감소하였다. 3. ANS-Me(L)보다 N-ANS(L)가 더 많은 성장량을 보여 안면 형태에 많은 영향을 줌을 알 수 있었다. 4. $N-A-Pog^{\circ}$ 은 연령증가와 더불어 감소하며 이는 하악골의 성장이 상악골의 성장량보다 빠르고 많았다. 5. 상하악 기저골 관계에서 Y-axis의 길이는 증가하지만 각도는 일정하게 유지되어 하악골은 두개저에 대해 일정방향으로 성장하였다. 6. 영구치 맹출과 더불어 Interincisal angle은 감소하였다.

A six week growth performance trial involving 450 birds was conducted to determine the dietary requirement of broiler chicks for available methionine (AM). Body weight gain was significantly (p<0.01) lower on high AM diet (1411 g/bird) than low AM (1470 g/bird) and normal AM (1466 g/bird) diets. The feed intake by birds ranged from $3241{\pm}25.69$ in high AM diet to $3321{\pm}25.69g/bird$ in low AM diet. The feed efficiency for the three diets having low, normal and high level of AM were $2.26{\pm}0.02$, $2.24{\pm}0.02$ and $2.30{\pm}0.02$, respectively. The results indicated that the birds fed high AM diet consumed significantly (p<0.01) more feed per unit body weight gain as compared to birds on low and normal AM diets.

The recombinant glycoprotein, LBD-005 (Lucky R & D Center, Biotechnology)stimulates the growth of stem cells and activates the development of the hematopoietic cell in a similar manner to the naturally occurring GM-CSF. This test was conducted to investigate if LBD-005 had any effect on fertility in male and female rats. Sprague-Dawley rats(88 of each sex) bred at KRICT, were dosed subcutaneously, at a volume of 2ml/kg body weight with LBD-005 at 0, 250, 500 or 1, 000mg/kg body weight. The male rats were dosed, from 6 weeks of asge, for 60 days prior to mating.

Ovariectomy induced hyperphagia was reported in various animal models. It was postulated that hyperphagia resulted in interstinal hypertrophy and hyperplasia. Therefore, this study was performed to compare the food intake and intestinal changes between ovariectomized rats(OVX) and sham operated rats(Sham). Results of this study showed that the food intake and body weight of OVX animal was significantly higher than those of Sham animal. This results confirmed the effect of ovarian hormone on the food intake regulation. Hyperphagia induced by ovariectomy influence the intestinal cell growth and showed hyperplasia determined by protein/DNA ratio. Maltase and alkaline phosphatase activity suggested that the intestinal cell was fully matured in body groups. There were no difference in weight of other organs, such as liver, heart and kindney between two groups.

Growth records over six generations of 686 pigs in SD-II Swine Line were used to estimate the genetic and phenotypic covariance functions for body weight as longitudinal data. A random regression model with Legendre polynomials of age as independent variables was used to estimate the (co)variances among the regression coefficients, thus the coefficients of genetic and permanent environmental covariance functions by restricted maximum likelihood employing the average information algorithm. The results showed that, using litter effect as additional random effect, a reduced order of fit did not describe the data adequately. For all five orders of fit, however, the change trends of genetic and phenotypic (co)variances were very similar from ${\kappa}$=3 onwards.
