A retrospective morphological study was conducted on 1677 lymph nodes which were removed surgically under the diagnosis of gastric carcinoma, breast carcinoma, colonic carcinoma, chronic gastric ulcer, and superficial lymph nodes nuder the diagnosis of reactive follicular hyperplasia at Chosun University Hospital during a period of 5 years from 1980 to 1984. The hematoxylin and eosin stained sections were examined to evaluate for any vascular changes. In selected cases further levels were prepared from the paraffin blocks for Gomori's reticulin stain. The vascular abnormalities were divided into 3 groups, such as hemangiomatoid, pan-nodal vasodilatation and miscellaneous types. The miscellaneous type included the proliferation of smooth muscle which encircled numerous small hilar arteries and veins. The results obtained were as follows: 1) The hemangiomatoid lesions were localized lesions which appeared to be associated with local malignancy, but infrequent in incidence. 2) A more frequent vascular abnormality was pan-nodal vasodilatation, which tend to affect many nodes in a single group and is relatively associated with chronic gastric ulcer. 3) Miscellaneous lesion was nonspecific and appeared both local malignancy and chronic inflammation. 4) All three vascular reactions were somewhat more frequent in female than male.

Journal of the Korean Ophthalmological Society 1995;36(12):2218-2224
Leber's hereditary optic neuropathy is caused by a single nucleotide change in the mitochondrial deoxynucleic acid(mtDNA). We identified a single guanine to adenine transition mutation in the mitochondrial DNA at nucleotide position 11778(Wallace mutation)in a 13 year old boy. To our knowldge, this is the first report confirming mtDNA mutation in Korea. This would be very helpful for the correct diagnosis of optic neuritis, optic neuropathy and optic atrophy of unknown etiology as well as for genetic counselling in the future.

In parentage testing DNA profiles are used to link the alleged father with paternity by matching their patterns. The probative value of a match is often calculated by multiplying together the estimated frequencies with which each particular VNTR or STR pattern occurs in a reference population. When this calculating method applies to the motherless case of paternity disputes, a calculation must usually be based on types determined for the child and the alleged father. In such case, the first consideration is to exclude a man from paternity of a child when the man did not have the child's paternal allele at some loci, or if the paternal allele cannot be determined, when the man had neither of the child s alleles. The second is to evaluate the DNA evidence when a man is not excluded by the paternal allele. This work is to provide theories of paternity analysis with three approach methods for the motherless case, and to evaluate their efficiency compared to the trio case when the man tested is not excluded. Consequently, the motherless case offers lower probability exclusion and questionable cumulative paternity index than those of the trio case as being typed with 14 STR loci(CSF1PO, TH01, TPDX, vWA, D5S818, D13S317, D7S820, D16S539, FGA, D21S11, FES/FPS, F13A1, D18S80, D17S5). Since the motherless case in paternity disputes is less efficient for paternity exclusion of the child, the use of genetic maker systems with the higher value of mean exclusion chance(MEC) and exact levels of the relative probability of paternity must be of importance considered in the analysis of such deficiency cases.

BACKGROUND: We compared thiopental sodium with propofol as induction agents under propofol-N2O anesthesia for cesarean sections. METHODS: We selected 68 pregnant women with a single fetus undergoing an elective cesarean section under general anesthesia and randomly allocated them to the thiopental sodium group (group N) or the propofol group (group P). Without premedication, thiopental sodium 5 mg/kg and succinylcholine 1 mg/kg were injected for induction in group N, and propofol 2 mg/kg and succinylcholine 1 mg/kg in group P. Propofol 10 mg/kg/hr was infused continuously with 50% N2O in both groups. We checked the blood pressure and the heart rate before and after injection. We analysed blood gas of maternal artery, umbilical artery, and umbilical vein at delivery and checked Apgar scores at 1 minute and 5 minutes after delivery. RESULTS: There was no significant difference in blood pressure, heart rate and Apgar scores between groups. Oxygen partial pressure (35.6 +/- 5.8 mmHg) and oxygen saturation (66.2 +/- 12.0%) of the umbilical vein in group P was higher than in group N (32.7 +/- 4.9 mmHg, 58.7 +/- 11.5%). Carbon dioxide partial pressure and pH did not differ between groups. CONCLUSIONS: There was no beneficial effect of thiopental sodium compared with propofol as an induction agent under propofol anesthesia. Propofol is a useful drug for cesarean sections.

5.The Effects of Nutritional Education Program on Nausea and Vomiting, Anorexia, Food Intake, and Nutritional Status of GI Cancer Patients Undergoing Chemotherapy.
Journal of Korean Oncology Nursing 2010;10(1):38-47
PURPOSE: The purpose of this study was to identify the effects of nutritional education program (NEP) on nausea and vomiting, anorexia, food intake, and nutritional status among GI cancer patients undergoing chemotherapy. METHODS: A nonequivalent, non-synchronized posttest design was used. Study subjects were conveniently selected 30 patients (15 subjects for each group) who were undergoing chemotherapy. The subjects of the experimental group received NEP which consisted of 2 educations and 1 counselling while they were hospitalized, and telephone counselling with nutritional supports after discharge for four times. RESULTS: The score of anorexia was lower and the amount of food intake was higher in the experimental group than those of the control group. However, there were no significant differences in levels of nausea and vomiting, weight, hemoglobin, albumin, and total protein level between the experimental and the control group. CONCLUSION: The findings demonstrate that the NEP was effective in alleviating anorexia and improving subjective food intake of GI cancer patients undergoing chemotherapy. These findings suggest that NEP can be a useful nursing intervention for preventing nutritional disorders for patients with GI cancer after chemotherapy.

A 45-year-old Korean woman visited our hospital complaining of poor vision after carbon monoxide (CO) poisoning. We have confirmed the presence of a point mutation at position 11778 in the ND4 gene of mitochondrial DNA. This case suggests that CO poisoning may precipitate the clinical expression of Leber's hereditary optic neuropathy (LHON). To our knowledge, this would be the first case report of clinical expression of LHON precipitated by CO poisoning.

OBJECTIVE: To study the relationship between plantar pressure and diabetic foot ulcer and the assessment the usefulness of plantar pressure measurement in diabetic patients. METHOD: The total 94 diabetic patients were enrolled in this study. The plantar pressure was measured by using EMED-SF. And the nerve conduction studies, physical examination, and history taking were done. Patients were divided into 3 subgroups, Group A: without neuropathy and past ulcer history (n=31), Group B: with neuropathy and without past ulcer history (n=44), Group C: with neuropathy and past ulcer history (n=19). RESULTS: 1) There were significant increase in the maximum peak pressure (MPP) and the pressure-time integral (PTI) values in the Group C as compared with the Group A and B (p<0.05). 2) As compared among the groups for each areas, the MPP and the PTI significantly higher in group C for heel, medial fore-foot, and lateral fore-foot area than in another two groups (p<0.05). CONCLUSION: The high plantar pressure was significantly related with diabetic foot ulcer history. The plantar pressure measurement may be useful in diabetic patients as a predictive and management aids of diabetic foot ulcer.

Gastric mixed adenoneuroendocrine carcinoma (MANEC) is an entity defined by World Health Organization in 2010, which is composed of adenocarcinoma and neuroendocrine neoplasm. This is a very rare type of tumor in the stomach, which is estimated to be one to two per one million people per year on gastrointestinal track. In general, as MANEC often shows a poor prognosis, early diagnosis of the disease is important for achieving a favorable outcome. However, due to its rarity and histological heterogeneity, it is hard to suspect this disease initially, and sometimes this tumor is misdiagnosed as adenocarcinoma. The present case was a 76-year-old man who was initially diagnosed with gastric tubular adenocarcinoma without distant metastasis. Only 1 month after a curative surgery, multiple liver metastases were newly detected. Retrospective pathologic review resulted in a revised diagnosis as a gastric MANEC, and the patient underwent palliative systemic chemotherapy to achieve partial response.

Syringoid eccrine carcinoma (SEC) is a rare cutaneous malignant tumor thought to be derived from eccrine sweat glands. It is usually present in the scalp and face and often occurs in the fourth to seventh decades of life. A 76-year-old female patient visited our department with a 3-year history of a lesion showing a 5×4 cm-sized erythematous firm plaque with ulceration on her right shoulder. Histological findings revealed a tumor consisting of numerous proliferating tubular structures with two layers of basaloid cells with cellular atypia. Some ductal structures showed a tadpole appearance. Based on these findings, the final diagnosis was SEC. The patient was treated with slow Mohs micrographic surgery and a full-thickness skin graft and did not show any recurrence during the follow-up period of 6 months. Herein, we report a very rare case of a 76-year-old woman diagnosed with SEC that developed on the right shoulder.
