Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.

The immunohistochemical (ABC method) studies on the ontogeny and localization of the catecholamine-synthesizing enzyme tyrosine hydroxylase (TH) were examined in rat brain from the 12th fetal day until the 9th postnatal day. The results obtained were as follows : 1. Tyrosine hydroxylase was first detected immunohistochemically at embryonic day 13(E13). At this stage, the TH-containing neurons were still migrating and cytologically immature. 2. The changes occuring from the early to the late prenatal stages of development appeared to be the result of an increase in the number and size of the TH-containing cells and in the length of nerve fibers. 3. The distribution of the TH-containing neurons at embryonic day 19(E19) more closely resembled catecholaminergic neurons in the adult rat brain : 1) a rhombencephalic group became the A1-7 ; 2) a ventral mesencephalic group became A8-10 ; 3) a ventral prosencephalic group and a few neurons ventral to the striatum became A11-14 ; and 4) the cells of the olfactory bulb corresponded to the A15. 4. The cytodifferentiation of the TH-immunoreactive neurons was accompanied by continued migration to form the collective catecholaminergic groups during ontogenesis. In addition, the morphology of the TH-immunoreactive neurons in the late prenatal stage resembled in the adult rat brain.

Cells immnunoreactive for somatostatin(SOM) and glucagon(GLU) were investigated in postnatal day 0, 7, 14, 28, 90, 180 and adult canine pancreas using light microscopic immunohistochemistry. Pancreatic SOM-immunoreactive cells were found in pancreatic acini, pancreatic duct, and pancreatic islet gradually. Pancreatic SOM-immunoreactive cells were more located in pancreatic parenchyme than pancreatic islet throughout pancreas by postnatal day 28. But there was change by the postnatal 3 months : pancreatic SOM-immunoreactive cells were more located in pancreatic islet than acini and duct. It is suggested that the number of the SOM-immunoreactive cells may not increase with age apparently. A small number of SOM-immunoreactive cells that showed GLU-immunoreactivity were also observed in canine pancreatic islet. The physiologic consequences of these changes remain to be determined. These results sugegest that SOM in the developing pancreas may relate to the secretion of pancreatic hormones.

Several glycosidase activities, α-galactosidase, β-galactosidase and β-fucosidase and their isozymes were founded in Trichosantes kirilowii root, Trichosantes radix. The activities of α-glucosidase, β-glucosidase and α-fucosidase were also assayed but were not detected. Those glycosidases were isolated and partial purified glycosidases by acid-treated Sepharose-6B, anion exchange Mono-Q HPLC, DEAE-Sephacel, butyl-toyopearl hydrophobic column chromatographies. However, these glycosidases need to be purified more homogeneous and characterized.

The present study was conducted to elucidate some characteristics of soy protein hydrolysates. The soy protein was obtained from defatted soy power by the treatment of n-hexan. The hydrolysates of soy protein were prepared from hydrolysis by bromelian and pepsin with the two kinds of samples of precooking for 30 min in steam oven and noncooking, and fractionated through Bio-gel P-4 column chromatography. Fractions of hydrolysates separated on the Bio-gel column chromatography were carried out to SDS-PAG electrophoresis, resulting to show some different bends from 66kD to 14.2kD of molecular weight. In addition, the fractions showed different activities of superoxide dismutase. From these results, it was found that the hydrolysates could be available to use in a lot of food industrial fields as new functional food materials because the hydrolysates had different characteristics in electrophoresis and could increase the activity of superoxide dismutase.
흰쥐 이자 Insulin과 Neuropeptide Y 분비세포의 발생에 관한 면역조직화학적 연구
장인엽,박태우,정윤영,김종중,문정석,김영택,안계훈,김남훈,선희매 조선대학교 부설 의학연구소 1999 The Medical Journal of Chosun University Vol.24 No.1
Cells immunoreactive to insulin(INS-IR) and neuropeptide Y(NPY-IR) were found in prenatal(E15, 17, 19) and postnatal(P0, 5, 10, 15, 30, adult) rat pancreas using immunohistochemistry. Pancreatic INS-IR and NPY-IR were detected by day E17. They were found initially in the interlobular pancreatic duct, intralobular pancreatic duct and pancreatic islet gradually. Especially, INS-IR was detected in the dorsal pancreatic bud by day E19. The INS-IR and NPY-IR patterns were nearly similiar to each other, and many cells revealed colocalization of INS and NPY until day P10. But there was a change between them by the day P15 ; central INS-IR cells and peripheral NPY-IR in the pancreatic islet. The number of pancreatic islets per square millimeter of pancreatic tissue were decreased, and the number of immunoreactive endocrine cells per islet was increased according to development. These results suggest NPY may play a role in the development of the pancreatic endocrine cells.

Attempts were made to investigate the levels of chemical components and detoxification of the salted puffer overies, Fugu xanthopterus, "Ggachibog" and Fugu rubripes rubripes, "Chambog", processing of solid salt mixtures containing sodium bicarbonate, during storage period. Fresh ovaries of the puffers were divided into three portions, sprinkled with a solid salt mixture containing 0,1 or 2% NaHCO₃, and were stored at room temperature for 12 weeks. The samples were examined at each step and assayed for pH, VBN, amino-N, toxicity and thin- layer chromatogram pattern. The results were summarized as follows: The values of pH were appeared to be different with the added amount of siodium bicarbonate and the values of pH were over 7.0 in a salt mixture containing 2% NaHCO₃. The change of VBN value was also revealed about 85mg/100g in A division and 90-100mg/100g in both B and C, respectively, in the salted ovary of puffer "Ggachibog" from 8 weeks. In case of salted product from the "Chamboh" ovary, it had slightly lower value than that of "Ggachibog" ovary. Also, the value of amino-N was increased until 4-6 weeks and was slowly down after the weeks in all samples. All salted products were found to lose most of the toxicity during storage period when the salt containing NaHcO₃was used for sprinkling. In the case of raw ovaries being weak toxicity below 5.0 MU/g or 24.1 MU/g, the toxicity of salted product was dropped near the level to be edible. Therefore there was significant detoxification of the puffer ovaries by the salt mixture containing sodium bicarbonate. Finally, the toxins isolated from each raw puffer ovary were detected to be TTX-related components by thin-layer chromatogrphy.

Variety of recent railroad markets arouses the need for steel sleepers. Steel sleepers have many advantages over conventional timber or PC sleepers with respect to safety, environment and economical efficiency due to less effort for maintenance. Weak points of timber sleepers are to cut trees and apply toxic creosote as well as to need frequent maintenances while it is difficult to apply PC sleepers to steel bridge or crossing and to recycle them completely. In this paper, technical trends are analyzed in order to develop suitable steel sleepers for domestic railroads.
