金賢洙,鄭淳英,盧景錫 慶尙大學校 1985 論文集 Vol.24 No.1

We obtain the Fraunhofer diffraction pattern for a regularly triangular aperture by the use of the He-Ne Laser. Experimental results are well satisfied with the following theoretical properties of the diffraction image: (i) Since the intensity continuously decreases there are not secondary maxima, (ii) there are not alternating bright and dark bands and (iii) there are three symmetric axes.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

이영호,김수일,박경란,노승무,김원식 충남대학교 의과대학 지역사회의학연구소 1992 충남의대잡지 Vol.19 No.1

For the study on the effects of aflatoxin B_1 and corticosteroid to the Kupffer cells and endothelial cells of the liver, aflatoxin B_1(1mg/kg) and dexamethasone(4mg/kg) were administrated to the 3 groups of rats; the aflatoxin B_1-treated group, the dexamethasone-treated group, and the aflatoxin B_1 and dexamethasone-treated group. The liver tissues were fixed by perfusion with 0.5% glutraldehyde and 0.5% paraformaldehyde solution at 1, 12, and 24 hours after the administration. The fixed liver tissues were cracked and observed Kupffer cells and endothelial cells under scanning electron microscope. The results were as follows; 1. In aflatoxin B_1-treated group, the Kupffer cells were destructed severely and the endothelial cells were destructed partially. 2. In dexamethasone-treated group, the cytoplasmic processes of the Kupffer cells were shortened, but the endothelial cells showed no morphological changes. 3. Destructive changes of Kupffer cells and endothelial cells in the aflatoxin B_1-treated group were reduced after administration of dexamethasone. 4. The large Kupffer cells were destructed and disappered after administration of aflatoxin B_1, but small Kupffer cells were found until 24 hours after administration. 5. In aflatoxin B_1 and dexamethasone treated group, Kupffer cells were destructed severely but the capacity to catch foreign particles were remained. Accordingly, it is considered that aflatoxin B_1 will destruct Kupffer cells severely and the endothelial cells partially, but dexamethasone will reduce the destructive changes of the Kupffer cells and endothelial cells induced by aflatoxin B_1 respectively.

Cadmium is well known toxic heavy metal which has been related with various pathologic conditions of liver, kindney, testis, cardiovascular system and central nervous system etc.. In this experiment, cadmium sulfate (1.2mg/100gm b.w.) was given intravenously into the mouse (Balb - C, b. w. 20 - 25gm) via tail vein for the study on morphological changes of liver. On the 8hours, 16hours and 24hours after administration, mice were sacrificed under ether anesthesia, liver was removed, then, a part of liver was fixed in 10% neutral buffered formalin solution, processed routinely, stained with hematoxylin & eosin, and observed under light microscope. Otherwise, the remainder portion of liver tissue was prefixed in 1.5% glutaraldehyde solution, postfixed in the 1% osmium tetraoxide solution, embedded with Epon 840, and observed under transmission electron microscope(H-7000, Hitachi Co.). The results obtained were as followings ; 1. On light microscopic observation, hemorrhagic necrosis at the zone Ⅰ and zone Ⅱ with congestion of hepatic lobules were found. 2. On transmission electron microscopic observation, cisternal dilation of RER & SER, autophagic vacuoles, myelin figures, and certain electron dense materials within the hepatocytes were found. Although this observations were limited in mice, the above findings of its acute effects on liver morphology will serve morphological basis for the better understanding of toxic effects on liver after chronic exposure or multiple interactions with other toxic substances.

Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.

These two imaging criteria, plus patient age, were used to develop a nomogram calculating the probability of involvement of ≥ 3 ALNs. The areas under the receiver operating characteristic curve of the nomogram were 0.852 (95% confidence interval [CI], 0.820 to 0.883) for the training set and 0.896 (95% CI, 0.836 to 0.957) for the validation set. Prospective application of the nomogram showed that 60 of 512 patients (11.7%) had scores above the cut-off. Application of the nomogram reduced operation time and cost, with a very low re-operation rate (1.6%).</P><P><B>Conclusion</B></P><P>Patients likely to have ≥ 3 positive ALNs could be identified by preoperative imaging.

Strumal carcinoid tumor of the ovary is a rare subtype of ovarian carcinoid tumors; it is characterized by an intimate mixture of thyroid and carcinoid tissues. We present a case of a 64-year-old woman who presented with the chief complaint of persistent, severe constipation for over 5 years; she was later found to have an ovarian strumal carcinoid tumor. Computed tomography showed a well-defined solid mass measuring 6.4 cm at the right adnexa. The patient underwent right salpingo-oophorectomy and was histopathologically diagnosed as having a strumal carcinoid tumor. Immunohistochemical examination showed immunoreactivity for peptide YY (PYY), which exerts an inhibitory effect on the peristaltic actions of the distal intestine. After surgery, the patient's constipation resolved rapidly, suggesting a correlation between PYY producing ovarian carcinoid tumor and constipation. This is the first case report of PYY producing primary strumal carcinoid tumor of the ovary associated with persistent, severe constipation from Korea.

본 연구는 서울지역에 거주하는 건강한 성인 남녀(남자 23명, 여자 10명) 33명을 대상으로 trans 지방 3.75 g을 첨가한 쌀 빵, 콩 빵과 밀 빵의 섭취가 식후 혈장에서의 지방산과 지질흡수에 미치는 효과를 확인하기 위하여 실시하였다. 시험군은 각 군 당 11명씩 3군으로 분류하였다. 쌀 빵은 밀가루 40 g과 쌀가루 40 g에 trans 지방 3.75 g을, 콩 빵은 콩가루 30 g과 밀가루 50 g에 trans 지방 3.75 g을 첨가하였고, 밀빵은 밀가루 80 g에 trans 지방 3.75 g을 첨가하여 식빵 형태로 각각 조제하였다. 대상자들은 8시간 공복 후 각각의 빵을 섭취하고 0, 1, 2, 3, 4시간 후 채혈하였고, 이는 혈중 지방산과 trans 지방산의 농도 및 지질 수준 분석에 이용되었다. 포화지방산인 C16:0과 C18:0의 수준은 밀 빵을 섭취한 군에서는 시간의 경과에 따라 유의적인 차이를 보였으나 콩 빵과 쌀 빵을 섭취한 군에서는 섭취 후 유사한 수준이었다. C16:0은 콩 빵과 밀 빵을 섭취한 군에서는 섭취 1시간 후에 peak에 도달하였으나 시간이 경과함에 감소하는 경향을 보여 섭취 4시간 후 밀 빵 군에서는 변화량은 섭취 전의 수준과 유사하였으나 콩 빵 군에서는 섭취하기 전보다도 낮아지는 것으로 나타났다. C18:0은 섭취 1시간 후 콩 빵과 쌀 빵을 섭취한 군이 밀 빵을 섭취한 군에 비해 유의적으로 감소하였으나 콩 빵과 쌀 빵 군 간에 유의적인 차이는 없었다. Trans 지방산인 C18:1t과 18:2t는 세 군 모두에서는 섭취 2시간 후 가장 높은 수준을 보였으며 섭취 4시간 후에는 콩 빵 섭취한 군에서의 C18:1t의 혈중 농도가 가장 낮았다. C18:1c은 섭취 4시간 후 콩 빵 군에서 가장 낮았고 쌀 빵 군에서 가장 높았다. 또한 콩 빵의 섭취는 TG의 증가를 효과적으로 억제하였다. 이상의 결과로 미루어 볼 때 콩 빵의 섭취는 밀 빵을 섭취했을 때보다 혈중 trans 지방산을 비롯한 포화지방산 농도와 TG의 수준을 저하하였으며 이것은 콩에 함유된 식이섬유와 생리활성물질들이 지방산과 지방의 체내 흡수율을 저하시키거나 흡수속도를 느리게 하는 때문으로 사료된다. 따라서 trans 지방산을 비롯한 포화지방산과 TG의 체내 농도를 저하시키기 위해서는 밀 빵보다 콩 빵의 형태로 섭취하는 것이 유익할 것으로 사료된다. It has been reported that trans fat (tFA) may have adverse or beneficial effect depending upon the position and number of double bonds. The presence of tFA in human tissues and fluids is related to dietary intake, intestinal absorption, metabolism and storage, exchanges among compartments. This study investigated the effect of breads containing tFA, soybean or rice on postprandial plasma fatty acid and lipid composition. 33 healthy volunteers were divided into 3 groups and fed soybean bread, rice bread or wheat bread groups containing equivalent amounts of tFA (elaidic acid rich, 3.75 g/day), respectively. Postprandial lipid profiles at 0, 1, 2, 3 and 4 hours after a respective meal were studied. Plasma fatty acid was extracted by the method of Folch and methyl ester of fatty and prepared by acid transmethylation and analyzed by Gas Chromatography. Peaks were identified using pure reference compounds and quantified. Postprandial data indicated that consumption of soybean and rice breads with 3.75 g tFA retarded the appearance of C18:1 and C18:2 tFA in plasma lipid compared to that of wheat bread. Futhermore, soybean and rice bread groups showed lower plasma saturated fatty acid levels than wheat bread group. Postprandial TG level was significantly lowered in soybean bread group compared to that of rice and wheat bread groups. These results imply that soybean bread with high dietary fiber content and biologically active substances may inhibit or delay lipid absorption.
