BACKGROUND/OBJECTIVES: Although it is crucial to identify those children likely to be treated in an appropriate nutrition rehabilitation programme and discharge them at the appropriate time, there is no golden standard for such identification. The current study examined the appropriateness of using Mid-Upper Arm Circumference for the identification, follow-up and discharge of malnourished children. We also assessed its discrepancy with the Weight-for-Height based diagnosis, the rate of recovery, and the discharge criteria of the children during nutrition rehabilitation. SUBJECTS/METHODS: The study present findings from 156 children (aged 6-59 months) attending a supplementary feeding programme at Makadara and Jericho Health Centres, Eastern District of Nairobi, Kenya. Records of age, weight, height and mid-upper arm circumference were selected at three stages of nutrition rehabilitation: admission, follow-up and discharge. The values obtained were then used to calculate z-scores as defined by WHO Anthro while estimating different diagnostic indices. RESULTS: Mid-upper arm circumference single cut-off (< 12.5 cm) was found to exhibit high values of sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio at both admission and discharge. Besides, children recorded higher rate of recovery at 86 days, an average increment of 0.98 cm at the rate of 0.14mm/day, and a weight gain of 13.49gm/day, albeit higher in female than their male counterparts. Nevertheless, children admitted on basis of low MUAC had a significantly higher MUAC gain than WH at 0.19mm/day and 0.13mm/day respectively. CONCLUSIONS: Mid-upper arm circumference can be an appropriate tool for identifying malnourished children for admission to nutrition rehabilitation programs. Our results confirm the appropriateness of this tool for monitoring recovery trends and discharging the children thereafter. In principle the tool has potential to minimize nutrition rehabilitation costs, particularly in community therapeutic centres in developing countries.

The effect of diets(high fat, high fat high energy, pectin, cellulose) on adipocyte of epididymal fat pads were investigated in 70 male rats for 8 weeks. The rats were assigned to a control(C), high fat(HF) and high fat high energy(HFHE) group for 4 wks. During the next 4 wks, reassigned to one of three treatments (high fat, pectin supplemented, cellulose supplemented) in the HF group and one of three treatment (high fat high energy, pectin, cellulose) in the HFHE group. Therefore, the total experimental groups were 7 (C, HF, HF-P, HF-C, HFHE, HFHE-P, HFHE-C). Parameters evaluated and compared for each diet were body weight, total energy intake, feed efficiency ratio and weight changes in epididymal fat pads. The results are summarized as follows ; 1) There was no significant difference in body weight gain among the groups. 2) Total energy intake was higher in the C group than other groups. 3) Feed efficiency ratio (F.E.R) of the HF and HFHE groups were greater than C group(2, 4 weeks). However, there were no significant differences between the HF and HFHE groups. 4) Epididymal fat pads(EFP 100g/B.W) of the FH and HFHE groups were higher than C group (2, 4 weeks). However, there were no significant differences between the HF and HFHE groups. There was no significant difference in weight gain of epididymal fat pads among the groups(8 weeks). 5) Cell number and cell size of epididymal fat pads of the HF and HFHE groups were higher than the C group. The pectin and the cellulose supplementation groups decreased cell number and cell size of epididymal fat pads. Especially, the pectin supplementation group decreased than the cellulose supplementation in HFHE group. Therefore, we can concluded that the HF and the HFHE diet has no effect on the epididymal fat pads.

A feeding trial was conducted on commercial broilers for a period of 35 days to determine the individual and combined effects of aflatoxin (AF) and T-2 toxin (T-2) on performance, organ weights and immune status. The efficacy of dietary glucomannan-containing yeast product (GYP) ($Mycosorb^{(R)}$) and hydrated sodium calcium aluminosilicate (HSCAS) in preventing the adverse effects of aflatoxin and T-2 toxin was also evaluated. Twelve dietary treatments ($4{\times}3$ factorial) comprising two dietary levels each of AF (0 and 2 mg/kg), T-2 toxin (0 and 1 mg/kg), GYP (0 and 1 kg/ton) and HSCAS (0 and 10 kg/ton) were tested on 720 commercial broiler chickens divided at random into 36 replicates of 20 chicks each (10 males and 10 females). Weight gain and feed intake were recorded weekly. Organ morphology and antibody titers for Newcastle disease (ND) and infectious bursal disease (IBD) were measured on the $35^{th}$ day. AF and T-2 toxin individually decreased weight gain and increased feed conversion ratio (FCR) (p<0.05). AF alone (p<0.05) increased weights of liver, kidney, gizzard and spleen and reduced thymus and bursal weights. T-2 toxin (p<0.05) increased liver and gizzard weights and decreased thymus weight. Both AF and T-2 toxin when fed individually affected ND and IBD titers in a significant manner. Significant interactions between AF and T-2 toxin were observed for their additive effects on weight gain, FCR, organ weights and antibody titers. Addition of GYP (p<0.05) improved weight gain, feed conversion efficiency and restored the organ weights. Antibody titers against ND and IBD were significantly improved with the supplementation of GYP. Supplementation of HSCAS (p<0.05) resulted in improvement in weight gain and restored organ weights in the groups fed AF alone, but not in T-2 toxin fed groups. HSCAS inclusion did not influence FCR in toxin fed groups. Addition of HSCAS (p<0.05) improved the antibody titers against ND and IBD only in AF fed groups. Thus, the results indicate that addition of GYP is effective in averting the individual and combined toxicity of aflatoxin and T-2 toxin in commercial broilers, while HSCAS is effective only against aflatoxin.

This study is to find out how the 4 types of calcium salt such as calcium carbonate, calcium phosphate, calcium lactate and calcium citrate in soy protein diet, the vegetable protein source, affect the calcium utilization in the body. To do so, calcium, phosphate and creatinine concentration and ALP activity in blood as well as the content of calcium and ash, the length, weight strength, and the calcium utilization in the bone were measured. Four groups of Sprague-Dawley male rats with the weight of around 180g were fed for 3 weeks with the experimental diet. Each group was fed with the isolated soy protein containing 14% of the diet and the above mentioned 4 types of calcium salt as the calcium source. The results are as follows; 1. There were no differences of the feed intake, weight gain, and feed efficiency among groups. 2. ALP activity in blood was sinificantly high in calcium lactate group(P<0.05), but there were no differences of concentration of calcium, phosphates, and creatinine in blood among groups. 3. The weight, calcium content, calcium ratio in ash and the strength of bone were low when calcium lactate was provided(P<0.05). 4. The content of calcium in the liver was high in calcium lactate group and calcium citrate group(P<.0.05). 5. The exceretion of feces was low in calcium lactate group(P<0.05) and the excretion of urine was also relatively low. In addition, the ratio of absorption and the retention of calcium were high(P<0.05). In summary, out of four types of calcium salt such as calcium carbontate, calcium phosphate, calcium lactate and calcium citrate when calcium lactate was provided the ALP activity in blood was high and the weight, calcium content, calcium ratio in ash and the strength of bone were low. In calcium utilization, the ratio of absorption and retention of calcium were high, however it has lower effect than 3 other calcium types in improving weight, the content of calcium and the strength of bone.

본 연구는 수정 전 단계인 생후 12~14개월령의 육성우에게 급여하는 사료의 적정 영양소 수준에 대해 알아보고자 에너지와 단백질의 비율에 따른 영양소 이용성 및 증체량에 미치는 영향을 평가하였다. 건물 섭취량은 T1 (TDN/CP 비율, 5.0:1), T2 (TDN/CP 비율, 4.5:1) 그리고 T3 (TDN/CP 비율, 4.0:1)가 비슷한 수치를 보였다. 분 중 회분은 T1이 11.07%로 T3 (9.69%) 보다 유의적으로 높아졌으며, TDN/CP 비율이 높아질수록 분 내 회분 함량도 증가되었다. 초기 체중과 상관없이 증체량은 실험 개시 후 30일째 사료 내 CP 비율이 높아질수록 유의적으로 증가하였으나 60일째에는 T2가 유의적으로 가장 높은 증체를 보였다 (p<0.05). TDN 비율이 감소하거나 단백질 비율이 높아질수록 증체량은 유의적으로 증가되었다(p<0.05). 실험 종료 시의 혈중 GPT는 T1과 T3 (112.6, 88.3 u/l)가 T2 (50.9 u/l) 보다 유의적으로 높은 수치를 나타냈으며, phosphorus는 T1 (46.3 mg/dl)이 다른 처리구보다 유의적으로 높은 값을 보였다(p<0.05). HDL cholesterol은 T2 (145.2 md/dl)가 T1 (121.0 mg/dl)과 T3 (132.3 mg/dl) 보다 유의적으로 높았으며, triglyceride는 T3 (40.6 mg/dl)가 T1, T2 (20.7, 29.0 mg/dl) 보다 유의적으로 높은 수치를 보였다(p<0.05). BUN 농도를 비롯한 그 외의 혈액 분석항목들에서는 처리구별에 있어서 유의적 차이가 없었다. 결과적으로 섭취량과 증체율에서는 TDN/CP 비율이 4:1이 가장 좋았으나 체지방 축적이 과잉될 가능성이나 혈액대사 수치를 함께 고려한다면 이 시기에서는 4.5:1의 비율이 바람직한 것으로 판단된다.

To elucidate the effect of antioxidant complex containing $\beta-carotene$, vitamin E, vitamin C, Ginkgo Biloba leaf extract and selenium on oxygen :tree radical production and detoxification system, rats were fed normal diet and normal diet with antioxidant complex 0.1%, 0.3% and 0.5% for 3 weeks. Feed efficiency ratio, changes in body weight, weight gain and amounts of feces of rat are similar in four groups. Liver weight per body weight and hepatic lipid peroxide weight increased in 0.5% group. However, hepatic glutathione contents in all antioxidant complex added groups were significantly increased compare with normal control group. On the other hand, the activity of xanthine oxidase was a little increased due to the amounts of antioxidant complex. Superoxide dismutase and gutathione peroxidase activity of 0.1% antioxidant complex added group were increased about $10{\sim}20%$ in comparison to normal control group. These results suggest that the supplementation of antioxidant complex 0.1% to basal diet may reduce the hepatic damage caused by free radicals.

Objectives : We investigated the effects of Herba Ephedrae and Rhizoma Amorphophalli on high fat diet induced obese male mice. Methods : 8 weeks old, high fat diet induced obese male mice were divided into 5 groups: C57BL/6 normal control, obese vehicle control, GGEx55 (Herba Ephedrae), GGEx61 (Rhizoma Amorphophalli), GGEx62 (Herba Ephedrae + Rhizoma Amorphophalli). After mice were treated with GGEx for 8 weeks, we measured body weight gain, food intake, feeding efficiency ratio, rectal temperature, fat weight, plasma leptin and lipid levels. We also took micro-computerized axial tomography (micro-CT) on the mice. Results : 1. GGEx55 and GGEx62 groups significantly decreased body weight gain and feeding efficiency ratio compared with vehicle control. But they significantly increased rectal temperature. 2. Plasma total cholesterol and LDL-cholesterol concentrations were significantly increased by GGEx55 groups, whereas were significantly decreased by GGEx62 groups compared with vehicle control. 3. GGEx55 and GGEx62 groups significantly decreased total, subcutaneous and visceral fat as well as fat areas in micro-CT analysis of abdomen compared with vehicle control. 4. Plasma GOT and GPT concentrations were significantly increased by GGEx55 groups compared with vehicle control. Conclusions : These results demonstrate that GGEx55 and GGEx62 effectively reduces body weight gain, feeding efficiency ratio in high fat diet induced obese mice, leading to the modulation of obesity. In addition, GGEx55 and GGEx62 decreases visceral adipose tissue mass and improves plasma lipids, suggesting that GGEx55 and GGEx62 may act as a therapeutic agent for obesity.

The trellis shaping is the method of selecting a minimum weight sequence from an equivalent class of possible transmitted sequences. It is perforemed by searching through the trellis diagram of a shaping convolutional code Cs. A shaping gain of the order of 1dB may be obtained with a simple 4-state shaping code. But when the rellis shaping is applied to multi-dimensional constellation, the shaping gain is decreased and the transmission delay is increased, which make it difficult to apply the trellis shaping to multi-dimensional constellation. In this paper, in order to solve these problems, the shell mapping algorithm is used for the mapper in the proposed trellis shaping. The simulatio result shows that the proposed trellis shaping is better than coventional trellis shaping to multi-dimensional constellation. In this paper, in order to solve these problems, the shell mapping on multi-dimensional costellation with respect to shaping gain and transmission delay. And the constellation expansion ratio (CER) and the capacity of transmitted injformation are identical to those of conventional trellis shaping on multi-dimensional constellation.

Bakery waste (BW) is much cheaper than barley (20 to 40% the price of barley). Bakery waste and barley grain have similar chemical composition; they contain 99 and 97% organic matter (OM), 1.1 and 1.8% fat, 18 and 15% neutral detergent fibre (NDF) and 14.0 and 14.5% crude protein (CP), respectively (DM basis). The objectives of this study were to determine the effect of substituting BW for barley grain in high concentrate fattening diets for lambs on nutrient intake, growth and carcass characteristics. Forty Awassi lambs (21.75${\pm}$1 kg) weaned at the age of 65 days were assigned randomly to four experimental fattening diets differing in BW ratio in a completely randomized design. The control diet (CON) contained 20, 60, 11, 7, and 2% (DM basis) wheat straw, barley grain, soybean meal, corn grain, and minerals and vitamin mix, respectively. Bakery waste substituted barley grain by 10, 20 and 30% of the diet DM in the LBW, MBW and HBW diets, respectively. The experiment lasted for 56 days. Dry matter intake (DMI) decreased (p<0.05) in LBW diet compared to the CON diet by approximately 10%. No further reduction in DMI was observed with the higher substitution levels. Metabolizable energy intake for the CON diet (3.6 Mcal/d) was also reduced (p<0.05) compared with LBW, MBW and HBW diets (3.4, 3.4 and 3.3 Mcal/d, respectively). Final body weight for lambs fed the CON diet (34.8 kg) was higher (p<0.05) compared with lambs fed the LBW, MBW and HBW diets (30.6, 32.0 and 31.1 kg, respectively). Growth rate for lambs fed the CON diet (232 g/d) was also higher (p<0.05) compared to lambs fed the LBW, MBW and HBW diets (170, 189, and 167 g/d, respectively). Feed to gain ratio was higher (p<0.05) for lambs fed the LBW, MBW and HBW diets (7.2, 6.6 and 7.3, respectively) compared with lambs that consumed the CON diet (5.7). Body weight gain cost was reduced by approximately 8% by the MBW and HBW diets as compared with the CON diet. Dressing percentage, full gut weight, empty gut weight and liver weights were all unaffected by the BW addition to the diets and averaged 48.9%, 6.8 kg, 2.8 kg and 0.444 kg, respectively. However, fat tail weight was increased (p<0.05) with the higher levels of the BW inclusion. In conclusion, substituting BW for barley grain reduced DMI and growth performance. However, when BW substituted barley grain at the 20 and 30% of the diet DM, body weight gain cost was reduced by approximately 8%.

This study was performed to determine possibility of compensatory growth of juvenile olive flounder fed a commercial feed during the summer season. Five treatments of fish with triplicates were prepared: C, S1, S2, S3 and S4. Fish in the control group (C) was hand-fed with the commercial feed to apparent satiation twice daily for 6 days a week during 6 weeks. Fish in S1, S2, S3, and S4 experienced 1, 2, 3, and 4 weeks of starvation before fed to satiation twice daily for 5, 4, 3, and 2 weeks, respectively. The feeding trial lasted far 6 weeks. Survival of flounder in C, S1 and S2 was significantly (P<0.05) higher than that offish in S4. Weight gain and specific growth rate (SGR) of flounder in C and S1 were significantly (P<0.05) higher than those of fish in S2, S3 or S4. And weight gain and SGR of flounder in S2 and S3 were significantly (P<0.05) higher than those of fish in S4. Feed consumption of flounder tended to increase with weeks of feeding. Feed efficiency ratio and protein efficiency ratio for flounder in C, S1, S2 and S3 were significantly (P<0.05) higher than those for fish in S4. Moisture content of the whole fish in C was lowest, but highest for fish in S4, respectively. Crude protein content of the whole fish in C was highest, but lowest far fish in S4, respectively. Crude lipid content of the whole fish in C, S1 and S2 was significantly (P<0.05) higher than that of fish in S4. In conclusion, full compensatory growth was obtained in juvenile olive flounder fed for 5 weeks after 1-week feed deprivation during the summer season. Compensatory growth of fish was well supported by improvement in feed efficiency ratio and protein efficiency ratio.
