To investigate nutritional and growth status of premature infants, survey was conducted against 19 premature infants admitted to Nursery of Pediatrics, Young nam University Hospital from Jan. 1984 to July 1988. Variations in feeding patterns as analyzed through the five feeding phases of dextrose, dextrose/hyperal, dextrose/formula, dextrose/hyperal/formula and formula. During 30days from birth, dietary intake, feeding phase, selective anthropometric measurements, biochemical parameters and demograpic information of premature infants were as follows: Distributions of birth weight by gestational age and apgar score showed preamture infants below 1499g were 31 weeks, 4/7(1min/5min) and premature infants from 1500g to 1999g were 33 weeks, 8/9(1min/5min) and premature infants from 2000g to 2500g were 33 weeks, 8/9(1min/5min). Average calorie intakes of premature infants below 1499g, premature infants from 1500g to 1999g and premature infants from 2000g to 2500g were 102.0㎉/kg/day, 119.3㎉/kg/day and 101.7㎉/kg/day. The mean values Na, K, Ca, P for all premature infants remained within the normal level for full term infants throughtout the 25days of this study period. Percentages of inital weight loss showned premature infants below 1499g were 5.4%, premature infants from 1500g to 1999g were 6.4%, premature infants from 2000g to 2500g were 11.4%. Percentages of inital weight loss of the amino acid injection group and the amino acid control group were 9.4% and 9.0%.

The normal physiological values of Korean mongrel dogs were studied, comparing them with foreign references, on the basis of control physiological data measured on 110 cases out of the dogs submitted to the experiments in our department. The hemodynamic measurements varied widely between the both limits of reported normal control data, with the mean value of heart rate $140.4{\pm}26.6$/min., and both the systolic and diastolic arterial blood pressures $137.2{\pm}31.7$mmHg and $104.7{\pm}14.4$ mmHg, as well as the venous pressure of $9.11{\pm}2.18$ cm.$H_2O$. Hematologically, the number of red blood cells $4,571,000{\pm}767,000$per cu.mm., the amount of hemoglobin $11.57{\pm}3.74$ gm/dl and the hematocrit $37.3{\pm}7.2$ per cent, were equally the values a little lower than the reported normal means. However, the white blood cells were within the reported normal limits both in number, $10,384{\pm}4,877$ per cu. mm and their differential counts with slightly broader ranges of variation. The platelet count was $149,800{\pm}47,000 $per cu. mm and was also far below the normal, while the coagulation time $9.03{\pm}2.69$min. and the prothrombin time $13.17{\pm}6.52$sec were within normal limits, though a little prolonged. The serum electrolytes, Na $146.6{\pm}10.44$mEq/L.,K $4.46{\pm}0.84$mEq/L., CI $118.3{\pm}7.88$mEq/L. and Ca $11.45{\pm}5.62$mg./dl, and the blood glucose level of $94.9{\pm}31.79$mg./dl were essentially not different from the reported normal values. The serum proteins, total protein $7.15{\pm}1.41$gm/dl., albumin $4.09{\pm}0.77$gm./dl. and globulin $3.18{\pm}0.88$gm/dl. were included near the higher limits of the reported normal levels. The thymol turbidity 0.1-3.04 units were normal in 10 cases, and the cephaline flocculation was within normal range except 2 cases out of 26 dogs, showing two positive in 24 hours. And the nitrogen series, NPN $34.61{\pm}10.29$mg/dl. and BUN $12.77{\pm}6.37$mg./dl. were normal. It may be concluded that from the point of view of hereby measured physiological data compared with the foreign references, the Korean mongrel dogs have a compatible laboratory data with only the special regards to their tendency toward anemia in red blood cell series.

To measure the proximate composition and mineral content of laver Porphyra yezoensis, we collected 30 raw and 30 dried laver from the major production area of the south coast of Korea (Busan, Goheung, Haenam, Wando). The approximate composition of a 100 g edible portion of raw laver was $89.9{\pm}1.4$ g moisture, $3.7{\pm}1.0$ g protein, $0.5{\pm}0.2$ g lipids, $2.1{\pm}1.8$ g carbohydrate and $3.9{\pm}0.6$ g ash. The approximate composition of a 100 g portion of dried laver was $8.9{\pm}1.6$ g moisture, $31.5{\pm}6.5$ g protein, $1.9{\pm}0.3$ g lipids, $48.4{\pm}6.5$ g carbohydrate and $9.3{\pm}1.1$ g ash. No clear regional variation in laver composition was observed. The mineral content of laver was expressed as dry weight. The mean macro mineral content per 100 g portion of raw laver was (in descending order): K ($1,979{\pm}863.0$ mg), Na ($1,063.2{\pm}498.8$ mg), P ($658.7{\pm}101.8$ mg), Mg ($432.3{\pm}83.5$ mg) and Ca ($394.2{\pm}136.5$ mg). In comparison, the mean micro mineral content of raw laver was (in descending order): Fe ($243.72{\pm}154.75\;{\mu}g/g$), Zn ($72.76{\pm}30.61\;{\mu}g/g$), Mn ($41.53{\pm}15.33\;{\mu}g/g$), Cu ($4.16{\pm}1.66\;{\mu}g/g$) and Ni ($0.43{\pm}0.70\;{\mu}g/g$) No clear regional variation in the mineral content of laver was observed; however, raw laver contained a higher mineral content than dried laver.

A study on quantitative phytoplankton samples, hydrographic conditions (temperature, salinity, dissolved oxygen), and nutrients has been performed in the southern waters of the Korean East Sea in early spring. Phytoplankton community showed close correlation with hydrographic conditions. This study area could be divided into three phytohydrographic regions; 1) East Korean Warm Water Region (a branch of Tsushima Current), 2) North Korean Cold Water Region, and 3) offshore water region not affected by other two water regions. Vertical distribution of phytoplankton is dependent upon stability of water column and nutrient concentration. Nutrient concentration shows characteristic distribution according to water masses. N/P ratio of ca. 3 in surface layer indicates that nitrogen is the major limiting nutrient in this area. N/P removal ratio was 12.54 ($r^2$ = 0.96), consistent with the Redified ratio. Primary nitrite maxima at the nitracline depths are thought to be formed by phytoplankton exudation. Secondary nitrite maximum was observed in coastal area with dissolved oxygen content of >5.2 ml/l much higher than <0.25 ml/l in other areas. The mechanism of secondary maximum is different from that of other regions, and whether it may be due to in situ degradation of organic matter by bacterial activity is still open to discuss.

The goal of this study was done for evaluating stability according to low-temperature storage of kimchi duruchigi supplemented with a hot water extract of Rubus coreanus Miquel (RCM). Total polyphenol and flavonoid contents in the RCM extract prepared from the hot water were detected by 293.34 μg CA/mg and 90.57 μg quecetin/mg, respectively. DPPH and superoxide radical scavenging activities of the extract were showed by relatively high values of 70.63 and 57.87%, respectively. Kimchi duruchigi was designed by control (non-treated), T1 (3% RCM extract), T2 (6% RCM extract), and T3 (0.1% ascorbic acid, a positive control). When compared with control and T3 groups, pHs of T1 and T2 groups supplemented with the RCM extract were gently changed depending on the storage time, and water holding capacities of T1 and T2 groups were improved in comparison with control group. Although meat color showed a tendency to most of increase according to the elapsed time, T1 and T2 groups showed less changes than that of control group. Lipid peroxidation appeared in a little bit changes regardless of the processing and storage days, but protein spoilages in T1 and T2 groups were found by lower changes when compared with the control group. As the results of sensory evaluation, T1 and T2 groups during storage had the better taste, flavor and acceptability than those of control and T3 groups. Therefore, we suggest that kimchi duruchigi supplemented with the RCM extract is a possible of improving the storage stability and product preference.

This study was conducted to examine the correlation among bone mineral density (BMD), hair and nail calcium and magnesium contents, and nutrient intakes in preschool children in Chungnam district. A total of 111 preschool children (61 boys, 50 girls) measured the anthropometric characteristics, the bone mineral density of carpus using DEXA and hair and nail calcium and magnesium contents were analyzed by ICP spectrometer. The average ages of the study subjects were 55.7 months in boys and 53.0 months in girls (3.8${\~}$7 years). The birth height and weight of subjects were 51.0 cm and 3.3 kg in boys and 50.3cm and 3.2kg in girls, respectively. The average height, weight, $\%$ body fat, and obesity index were 111.6 cm, 19.6 kg, $15.0\%,\;96.1\%$ in boys and 108.6 cm, 18.5 kg, $17.5\%,\;98.1\%$ in girls, respectively. The bone mineral density in carpus was $0.25 g/cm^2$ in boys and $0.24 g/cm^2$ in girls. The hair calcium and magnesium contents were 440.9 ppm, 16.4 ppm in boys and 373.2 ppm, 28.9 ppm in girls. The nail calcium and magnesium contents were 9.4 ppm, 2.1 ppm in boys and 10.4 ppm, 2.4 ppm in girls. The intakes of energy, calcium, iron, zinc, vitamin A. niacin, and vitamin C did not meet the Korean RDAs. The ultradis and average carpus BMD were positively correlated to the plant calcium intake (p < 0.05, p < 0.05). And the ultradis, distal, and average carpus BMD were positively correlated to the plant iron intake (p < 0.05, p < 0.05, p < 0.05). The average bone mineral density in the carpus was positively correlated to the nail magnesium content (p < 0.05). Therefore, more systematic studies to investigate the roles of iron and calcium intakes, nail magnesium content in bone development of preschool children were required.

Purpose: To assess the influence of cyclooxygenase-2 (COX-2) expression on the survival of patients with a combination of rectal cancer and lymph node metastasis. Materials and Methods: The study included rectal cancer patients treated by radical surgery and postoperative radiotherapy at the Dong-A university hospital from 1998 to 2004. A retrospective analysis was performed on a subset of patients that also had lymph node metastasis. After excluding eight of 86 patients, due to missing tissue samples in three, malignant melanoma in one, treatment of gastric cancer around one year before diagnosis in one, detection of lung cancer after one year of diagnosis in one, liver metastasis in one, and refusal of radiotherapy after 720 cGy in one, 78 patients were analyzed. The immunohistochemistry for COX-2 was conducted with an autostainer (BenchMark; Ventana, Tucson, AZ, USA). An image analyzer (TissueMine; Bioimagene, Cupertino, CA, USA) was used for analysis after scanning (ScanScope; Aperio, Vista, CA, USA). A survival analysis was performed using the Kaplan Meier method and significance was evaluated using the log rank test. Results: COX-2 was stained positively in 62 patients (79.5%) and negatively in 16 (20.5%). A total of 6 (7.7%), 15 (19.2%), and 41 (52.6%) patients were of grades 1, 2, and 3, respectively for COX-2 expression. No correlation was found between being positive of COX-2 patient characteristics, which include age (<60-year old vs. $\geq$60), sex, operation methods (abdominoperineal resection vs. lower anterior resection), degrees of differentiation, tumor size (<5 cm vs. $\geq$5 cm), T stages, N stages, and stages (IIIa, IIIb, IIIc). The 5-year overall and 5-year disease free survival rates for the entire patient population were 57.0% and 51.6%, respectively. The 5-year overall survival rates for the COX-2 positive and negative patients were 53.0% and 72.9%, respectively (p=0.146). Further, the 5-year disease free survival rates for the COX-2 positive and negative patients were 46.3% and 72.7%, respectively (p=0.118). The 5-year overall survival rates were significantly different (p<0.05) for the degree of differentiation, N stage, and stage, whereas the 5-year disease free survival rates were significant for N stage and stage. Conclusion: Being positive for and the degree of COX-2 expression did not have a significant influence on the survival of rectal cancer patients with lymph node metastasis. However, N stage and stage did significantly influence the rateof survival. Further analysis of a greater sample size is necessary for the verification of the effect of COX-2 expression on the survival of rectal cancer patients with lymph node involvement.
