The $3{\times}3{\times}30$ ($cm^3$) sized lumbers of Populus alba-grandulosa L. were treated with four fire-retardant solutions of ammonium sulfate, monoammonium phosphate, diammonium phosphate and aluminium chloride for 1, 15, 30, and 60 minutes and 1, 3, and 7 days. Thereafter they were air-dried and burned at high temperature about $1,800^{\circ}C$ and for short time of five minutes. This study estimated the relationship between absorbed chemical amounts and rate of weight loss or residual bending strength of these burned lumbers. The results were as follows: 1) In absorption amount of fire-retardant chemicals, diammonium phosphate showed the largest, aluminium chloride the smallest, but monoammonium phosphate and ammonium sulfate showed similar level. 2) The absorption amount of chemicals was decreased with the increase of specific gravity in the same species except aluminium chloride. 3) The rate of weight loss was decreased as the absorption amount of chemicals increased, especially monoammonium phosphate was most effective. 4) The MOR value of the residual bending strength was increased as the absorption amount of chemicals increased and especially monoammonium phosphate showed the most efficient effect. 5) Aluminium chloride showed more striking increase of MOR value of residual bending strength with the increase of absorption amount than any other chemical, therefore its MOR value was similar to the maximum MOR value of the most effective monoammonium phosphate. 6) The correlation between weight loss and MOR value of the residual bending strength was negative and aluminium chloride showed the most striking negative relation, but the others showed similar trends. 7) The correlation between work to proportional limit and absorption amount of chemicals was positive and the degree of increase in work to proportional limit was most in aluminium chloride, and the next, in monoammonium phosphate and diammonium phosphate in turn. 8) The correlation between work to maximum load and absorption amount of chemicals showed positive and diammonium phosphate revealed the best result and aluminium chloride showed better results than other two chemicals.

Introduction The effects of Bojungikkitang on the immunosuppression induced by methotrexate in rats were investigated in this experiment. The multiple parameters of immunity assessed in. each rats includes the rate of body weight loss, weight changes in thymus, spleen and axillary lymphnode. The number of lymphocyte and CD4+ T cell count in blood, thymus, spleen and axillary lymphnode were also measured. Methodology Male Sprague-Dawley rats were chosen as an experiment object and were divided into 3 groups by a random selection. Each group consisted 6 rats. The normal group didn't receive any treatment. The control group was administered methotrexate for 4 days. The sample group was administered with both Bojungikkitang and methotrexate for 4 days. The dosage of medication was 2cc/day, 1cc given at 10AM and another 1cc given at 5PM. Results The rate of body weight loss was significantly decreased in the sample group. The weight of thymus was significantly increased in the sample group while the weight of spleen did not show much increase. Blood CD4+ T cell count, thymus lymphocyte count, thymus CD4+ T cell count, spleen lymphocyte count, spleen CD4+ T cell count and axillary lymph node CD4+ T cell count were significantly increased in the sample group while blood lymphocyte count and axillary lymphnode lymphocyte count did not show much increase. Conclusion As one can witness from the above results, administration of Bojungikkitang played potent role in increasing immune system among the rats treated with methotrexate which induces immunosuppression. Overall increase of lymphocyte count and CD4+ T cell count in the sample group with Bojungikkitang effectively proves its ability to boost the immune system.

The effects of an anabolic steroid, nandrolone phenylpropionate(NPP), on body weight gain and body protein, and muscle protein metabolism were inestigated in adrenocorticotrophic hormone(ACTH)-treated male and female rats. Daily injections of 100ug/day of ACTH for 7-8 days caused a cessation of growth in females and a net loss of body weight in males which were associated with significant reductions in body protein content. However, food intake was not affected by ACTH in either sex. The weight, protein content and fractional rate of protein synthesis, measured in vivo, of gastrocnemius muscle were all significantly reduced in both sexes. NPP at a dose of 4mg/kg body weight prevented the reduction in body weight gain in ACTH-treate females but not in males. However, boy protein content was increased by NPP in both sexes which was associated with increases in the weight, protein content and fractional rate of protein synthesis of gastrocnemius muscle. ACTH treatment caused a marked increase in plasma concentrations of corticosterone in both sexes. NPP suppressed much of the increases in corticosterone concentrations in both sexes. The results of the present study suggest that NPP exerts at least part of its anabolic effect by reducing plasma concentrations of catabolic glucocorticoid hormones, through suppressing the response of the adrenals to ACTH.

A reproductive potential trial using randomized complete block design with $3{\times}3{\times}2$ factorial, was conducted on 84 Baluchi yearling ewes. Ewes grazed on rangeland dominated by Artemisia maritime and Holoxylon grifthii with or without flushing and supplementation of barley grain (BG) and cotton-seed-cake (CSC) during premating, late pregnancy and lactation of 90 days. Analysis of variance revealed that conception rate which ranged 64.28 to 85.71, was significantly greater (p<.05) in ewes flushed with CSC followed by ewes under BG or control feeding regimes. During the gestation period, liveweight of ewes changed from 31.24 to 21.2 kg. A loss of 32% of initial body weight was observed at lambing. Losses in live weight of ewes, regardless the supplementation, were uniform and non-significantly different. Live weight of ewes at lambing and weaning were also similar. Birth weight of lambs was significantly different at p<.05. Lambs born to larger ewes seemed to be heavier than lighter ones. Lambs suckling to ewes with losses in body weight during lactation gained more weight which was significantly different at p<.05. In the paper, factors affecting the conception rate, changes in liveweight of ewes during gestation and lactation and subsequently growth of lambs are discussed.

To understand the effect of powder characteristics on the thermal debinding behavior, PIM parts produced with powders with different particle sizes and particle shapes were examined to determine their weight losses during thermal debinding. The results show that the average diameter of the pore channel in the compact increased when the temperature increased and when coarse powders were used. However, the weight loss rates did not increase proportionally with the pore size. This suggests that the different powders that are frequently used in PIM parts do not affect the thermal debinding rate significantly. This is because the pore size is much larger than the mean free path of the decomposed gas molecules. Thus, the diffusion rates of the gases are not rate-controlling in thermal debinding. The controlling mechanism of the thermal debinding rate is the decomposition of the backbone binder in the PIM parts.

This research is about effects of obesity adults participating in 12weeks of boxing diets program on weight loss, blood pressure and blood sugar improvements. The exercise program was conducted three times a week with a maximum heart rate of 50 to 65 percent for first to forth weeks and 65 to 85 percent for fifth to twelfth. The study included 59 obese people in their 20s and 50s, with a BMI of 25kg/m2 or higher, blood pressure of 140/90mmHg, and high blood pressure and diabetes patients of 125 mg/dl per fasting blood sugar. The following results were obtained by observing the results before and after the boxing exercise program. High blood pressure, diabetes, high blood pressure + diabetes after 12 weeks showed significant weight, BMI and body fat reduction, as well as significant decrease in blood pressure and fasting blood sugar. Consequently, through this study, obese adults can lower their weight, blood pressure, and blasting fasting blood sugar through a 12-week high-strength boxing exercise program and it is believed to help improve and prevent obesity, cardiovascular disease and metabolic diseases.

Purpose: The aim of this study was to analyze the correlation of gestational age and birth weight with weight gain of very low birth weight infants(VLBWI) during their hospital stay. Method: This is a 5 year retrospective study of which data were collected through review of medical records. Subjects were 124 VLBW infants with a birth weight more than 1000g and less than 1500g who received neonatal intensive care at the university hospital between January 1, 1997 to December 31, 2001. Result: After calculating the z scores of birth weights and discharge weights, z scores of discharge weight and birth weight were compared with the median weight of a fetus of comparable gestational age based on an intrauterine growth reference. There was a significant difference between z scores of birth weight and discharge weight(t=11.60, df=122, p=0.000). Regardless of intensive care during the prolonged hospital stay, VLBW infants showed slow growth rate compared with the median weight of a fetus of comparable gestational age. Conclusion: VLBW infants developed a poor velocity of weight gain during the prolonged hospital stay after birth. The development worsened during the period of physiological weight loss and regain, and they did not reach to comparable growth rate of normal fetus even at the time of discharge. This poor growth velocity of VLBW infants influence negatively for their future growth. Therefore nureses who work at the neonatal intensive care unit must develop an effective nursing intervention protocol to promote the velocity of weight gain and to conduct the parental educational sessions to emphasize the importance of weight gain for VLBW infants at home.
