For this experiment frist the fermented Soybean Meju was prepared by domestic ordinary method of Korean and concentrated Meju suspensoidal extract was made for toxicological test sample on mice and rat. Even the oral dose of 10g extract per kg of mice had not any acute toxicity. So the median lethal dose(LOD50) is lilely to be much greatr or not to be. In comparison of the average weight gain rate for 4 weeks the control and test groups of 0.308g Ex/rat kg and 9.24g Ex/rat kg daily were the much the same as about 19% but 3.08g Ex/rat kg group waas exceptionally 2.7% higher than control For this period all test groups did not show any abnormality in appearance and anatomic findings. In serum GPT GOT alkaline phosphatase and blood urea nitrogen value there were no difference significantly between control and the test groups of 0.308g/rat kg and 3.08g/rat kg but 9.24g/rat kg group was some what higher than control. Especially in cholesterol alkaline phosphatase and blood urea nitrogen value 9.24g/rat kg group or 28days had 100mg/이 37.5u 32mg/이 respectively which were increased significantly. The pathological findings of all test groups especially 9.24g/kg group did not showed any characterized sign of acute or subacute liver damage or intestine lesion. So it is supposed that there is not any tocixants originated from some molds in fermented Korean domestic Meju which is prepared traditionally in winter.

In this presented study, we established a method for diagnosis of porcine epidemic diarrhea(PED) by in situ hybridization(ISH), which made distinct progress in diagnostic pathology. We also carried out the retrospective diagnosis through ISH to assume the exact time of the first outbreak and incidence of PED in Korea. The outbreak of PED in Korea reported in 1992. However, since the end of 1980's, some researches of pig-industry have already suspected the outbreak of PED, not transmissible gastroenteritis(TGE). In this experiment, we performed the ISH using 80 formalin-fixed and paraffin-embedded tissues of porcine intestine which were requests for pathological diagnosis from 63 farms whose primary sign was diarrhea from 1984 to 1991. We prepared biotinylated cDNA probe(492base pairs) for ISH by nick translation method and carried out the ISH, using $Microprobe^{TM}$ capillary action system(Fisher $Biotech^R$). We detected PED virus in intestinal mucosa of 2 cases in 1992, 1 case in 1988, and 1 case in 1987. As a result, we assume that the outbreak of PED in Korea have already started since 1987.

From 2006 to 2009, 50 pigs suspected of enteritis associated with porcine circovirus type 2 (PCV-2) (EAPC) were collected. Gross and histopathologic examinations and immunohistochemistry (IHC) were performed on the small intestine of 50 pigs. The pigs with EAPC were concentrated in grower pigs (68%), and diarrhea (84%) was the most common clinical sign. Grossly, the walls of the small intestine were thickened, and mesenteric lymph nodes were enlarged. The histopathologic features in the small intestine with EAPC were characterized by lymphoid depletion, histiocytic infiltration, and formation of basophilic grape-like inclusion bodies and multinucleated giant cells in gut-associated lymphatic tissue (GALT) and lamina propria. According to IHC, PCV-2 antigens were more intense and distributed widely in GALT (98%) than lamina propria (82%) of the small intestine. Co-infection with other enteric pathogens was detected in 26 pigs (52%). Twenty-four pigs (48%) were confirmed to be a PCV-2 single infection. Collectively, infected PCV-2 in the small intestine may induce an immunosuppressive status of individuals and then allow secondary co-infections in the digestive system. This study shows that PCV-2 can induce diarrhea and enteric lesions in pigs without a co-infection of other enteric pathogens.

Acute toxicity of a combined preparation of the standardized extracts Scutellaria baicalensis GEORGI and Salvia miltiorrhiza BUNGE in a ratio of 3:1 was examined in male and female ICR mice. Mice were treated with the test substance intragastrically at a dose of 0 mg/kg, 5 mg/kg, 50 mg/kg, 500 mg/kg or 2,000 mg/kg and observed for two weeks. No death or abnormal clinical sign was shown during the observation period. Also there were no difference in net body weight gain, organ weight, and gross pathological findings at the terminal sacrifice. The results suggested that acute oral toxicity of a combined preparation of the standardized extracts is very low at the conditions employed in this study.

Objectives: This study was designed to evaluate the methods of diagnosis and treatment of thyroid nodules. Materials and Methods : We performed a clinical review of patients with thyroid nodules, who were surgically treated at the Department of Surgery, College of Medicine, Chosun University from January 1996 to December 1998. Results: 1) The patients were divided into two groups; 65 patients(80.2%) with benign nodular disease and 16 patients(19.8%) with malignant disease. 2) The sex distribution showed a preponderance of females with a ratio of 5.2:1 in benign nodular disease and 3:1 in malignant disease. Benign nodules were more prevalent in patients in their 40's as compared to malignant nodules in patients in their 50's and 60's. 3) The most common duration of illness was 3 months, occurring in 45.7% of the total cases. 4) The most prominent symptom and sign was a palpable nodule in the anterior aspect of the neck. 5) The location of the nodule was ; 41 cases in the right lobe, 29 cases in the left lobe, and 11 cases in both lobes. 6) Thyroid scanning of 40 patients revealed cold nodules in 90.6% of benign nodules and in all malignant disease. 7) Fine needle aspiration cytology were performed in 32 cases of the 81 patients. Comparing with postoperative pathological findings, the results were the same in 87.5% of 32 cases. 8) Intra-operative frozen section study was performed in 56 cases of the 81 patients. Comparing with postoperative pathological finding, the results were same in 96.4% of the 56 cases. 9) The histopathological classification revealed that adenomatous goiters were the most common benign disease and papillary carcinomas were the most common malignant disease. 10) The most frequently employed operation for benign nodules and malignant disease was unilateral total lobectomy. When the metastasis was confirmed, lymphadenectomy and radical neck dissection was performed in malignant disease. 11) Important postoperative complications were transient hoarseness, transient hypocalcemia, hypothyroidism, wound bleeding, and hoarseness. Conclusions: The results of this study suggest that palpable nodules in anterior aspect of neck is revealed cold nodule by thyroid scanning and malignancy by fine needle aspiration cytology, which should be removed surgically. There is no difference in complication and survival rate with type of operation and lymphatic dissection. Therefore, procedure of operation is dependent on the site of nodule and involvement of lymph node.

The following conclusions are obtained from the studies on the chapters concerning phisiology, pathology, daily conduct, materia medica, pulse, and urinalysis from , of the "Four Tantras". 1. The theoretical basis forming the Tibetan Medicine is the substance of phlegm, bile, and wind each of which is divided into five kinds. These phisiological substances can be transformed into pathological factors when certain environment is formed. 2. In embryology, the semen of the father and menstral blood of mother is considered the most important condition in conception, and the Five factors are regarded as important. There is a detailed explanation of development of the fetus while it stays in the womb of mother during 38weeks, such as the formation of the viscera, channels, sense organs, etc. 3. There is metaphor which compares the human body with the king's palace. With the development of human anatomy, there is the detailed anatomical picture of anterior and posterior aspects of human body. And also there is the measurement of physiological constitution and the three fluids. 4. In division of the channels, they concerned the now of the blood and distribution of the nerve fibers, and each channel is connected with one another. The division of the cannel is namely embryonic channel, channel of existence, channel of connection, and the course of life principle. 5. The seven bodily constituents and three factors of phlegm, bile, and wind are important in sustaining the life of human body as well as growth and maturization, and when their equilibrium is broken, the human body is degnerated, and finally death comes. 6. The signs of death is divided into distant sign, remote sign, certain sign. and uncertain sign, and is used as a clue in diagnosis of the disease. Especially there is a mention about the mechanism of the dreams, and different dreams according to the condition of the patient. 7. In pathology, there is the cause of the disease, the environmental factors which can induce disease, the path by which disease come into the human body, the characteristics of the disease, and the kinds of disease. 8. There is a mention about the conduct, and it is divided into the daily conduct, the mental attitude, and the side-effects which can occur when one puts up with the physiological actions of the body. 9. The daily diet is divided into food and beverage. The food is divided again into grain, meat, fat, boiled food, and spiced food, and the beverage into milk, water, and wine. 10. The pulsation should be taken in lift hand to diagnose heart, small intestine, stomach, spleen, kidney, reproductive organ, and in right hand jungs, large intestine, liver, gall bladder, kidney, and bladder. In the healthy person, the pulse moves 5times in one perspiration, and the type of pulse is constant while the pulse moves 100times. But unhealthy person's pulse is different from this. The urinalysis is the unique part of Tibetan Medicine, and is important in examination of the disease. One should decide which of the three factors are dominant by the obervation of the color, amount of the steam and how long it lasts, odour, foam, and the shape of the swirl in three different states when the urine is hot, warm, and cold. One can determine the life of the patient and which viscera is the cause of the disease by the pulse, and whether the nature of the disease is hot or cold by the urinalysis. 11. The materia medica contains gemstones, minerals, plateau medication, and meat products.

Purpose: Microcystic adnexal carcinoma is a rare malignant appendage tumor, first described by Goldstein et al in 1982. Here, we present our experience in treatment of a case on the lower lip. Methods: A 52-year-old female with an asymptomatic nodule on the chin, previously misdiagnosed as trichoadenoma by needle aspiration biopsy, was treated by wide excision combined with multiple circumferential frozen biopsies. Results: Pathological examination revealed typical features of microcystic adnexal carcinoma, such as basaloid and squamous cells forming nests and cord-like patterns, horn cysts, and minimal cytologic atypia. The patient has been followed up for 6 months. No sign of recurrence is noted to date. Conclusion: Differentiation from other benign adnexal neoplasms is important for its appropriate treatment. Differentiation can be difficult histologically because it is difficult to acquire an adequate biopsy due to its invasiveness, and clinically due to its asymptomatic and slow growing features. Complete excision is the key treatment, but it may not always be the best solution considering the huge defect that may result and the low incidence of metastasis & deaths owing to the tumor. We add this case to the approximately 300 cases reported worldwide with a review of literature.

Purpose: Alimentary tract duplication (ATD) is a rare congenital condition that may occur throughout the intestinal tract. Clinical symptoms are generally related to the involved site, size of duplication, or associated ectopic mucosa. This study aimed to identify clinical implications by anatomical locations and age group and then suggest a relevant management according to its distinct features. Methods: We retrospectively reviewed the clinical data of pediatric patients who received a surgical management due to ATD. Furthermore, data including patients' demographics, anatomical distribution of the duplication, clinical features according to anatomical variants, and outcomes were compared. Results: A total of 25 patients were included in this study. ATD developed most commonly in the midgut, especially at the ileocecal region. The most common clinical presentation was abdominal pain, a sign resulting from intestinal obstruction, gastrointestinal bleeding, and intussusception. The non-communicating cystic type was the most common pathological feature in all age groups. Clinically, prenatal detection was relatively low; however, it usually manifested before the infantile period. A laparoscopic procedure was performed in most cases (18/25, 72.0%), significantly in the midgut lesion (p=0.012). Conclusion: ATD occurs most commonly at the ileocecal region, and a symptomatic one may usually be detected before the early childhood period. Surgical management should be considered whether symptom or not regarding its symptomatic progression, and a minimal invasive procedure is the preferred method, especially for the midgut lesion.
