Breast cancer is one of the most common cancers and causes several complications in females. Currently, MRI is a necessary method for preoperative studies in patients with breast cancer. A high frequency of breast MRI can lead to an increase in the number of incidental extramammary findings. Moreover, it can provide accurate preoperative workup; therefore, the prognosis of patients can be improved. Herein, we provide several extramammary findings, including the mediastinum, lung, upper abdomen, bone, and soft tissue, correlating with US, chest CT, liver MRI, PET-CT, and bone scan.

Suppressor of cytokine signaling (SOCS) is known to be as a negative feedback regulator in Janus kinase signal transducer and activator of transcription signaling. Highly conserved SOCS box domain was cloned from a Korean malaria vector, Anopheles sinensis. Sequence analysis indicates that it has identity to Anopheles gambiae (96%), Aedes aegypti (94%), Drosophila melanogaster (78%), Mus musculus (72%) and Homo sapiens (72%), respectively. Tissue specificity RT-PCR demonstrated that the expression level of AsSOCS transcript was high at abdomen, midgut, and ovary, whereas developmental expression patterns showed that the level of AsSOCS was high at egg, early pupae, and adult female. On the other hand, RT-PCR analysis after bacterial challenge showed that SOCS mRNA was strongly induced in larvae. In addition, it was also induced by various immune elicitors such as lipoteicoic acid, CpG-DNA, and laminarin. It seems that AsSOCS, repressor of JAK-STAT pathway, is highly conserved in mosquito, and may play an important role in mosquito innate immune response.

Assessing the exposure dose and the obtained image during the abdominal radiography with 128-slice MDCT scanner and 4-slice MDCT scanner which are recently being used in clinics using the body tissue-equivalent phantom and the glass dosimeter, the results were as follows. During the CT test for the abdomen, the absorbed dose was $35.8{\pm}0.46mGy$ in 4-MDCT, and $19.03{\pm}0.25mGy$ in 128-MDCT, which indicated that the radiation dose necessary to obtain the image meaningful to diagnosis was required less by 128-MDCT(P<0.05). As a result of analyzing the image obtained from the abdominal test using MDCT with a 5-point Likert scale, 4-MDCT showed the result of 3.52 points, and 128-MDCT showed the result of 4.01 points, that is, the image quality of 128-MDCT was evaluated high, and there was a statistically significant difference. In the results above, it is considered that 128 slice MDCT scanner will be much used later as it can reduce the radiation exposure, and make us obtain the high quality of image.

This study was performed to analyze the wearing practice and the purchasing characteristics of jeans in order to offer basic data to produce superior jeans made of denim with small flexibility and to improve the wearing comfort. The questionnaire were 236 Korean women from the age of 10th to 50th. For data analysis, descriptive analysis and crosstabs were used. The results were as follows, in the purchasing characteristics, when the women of 10th to 30th decided to purchase jeans they considered fashion, design and price rather than wearing comfort. But the women of 40th to 50th considered that wearing comfort is the most important factor. The 10th is found the best preferred jean is wide straight style, the 20th is straight style, the 30th is boots cut style and the 40th to 50th is straight style. In wearing practice, there was a difference among age groups on the region that felt uncomfortable when wearing jeans. As the age increases, the abdomen size also increases. Most people answered that they mend jeans after purchase for length, without any relation with age. The reason why consumers prefer jeans with middle length between the crotch and waist and also purchase jeans with a short length is because they look refined and neat. This informs us that the short length between the crotch and waist does not match with ease and comfort, which are the images of jeans in the past. Recently premium jean brands are competing to show Low Rise Jeans, which seems like a Premium Jean=Low Rise Jean formula is created. Some manufacture companies are recklessly copying foreign designs that does not fit Korean's body shape. However, as mentioned in this study results, there is a clear difference between designs that they think consider as aesthetic and functional. Therefore, it is considered necessary for developing designs for jeans that can satisfy both aesthetic appreciation and functions for Korean consumer's body shape and each age group.

It has been evident since 1972 that computed tomography(CT) can play an important role in treatment and managment of the cancer patients as four steps; diagnosis, satging Treatment and follow-up. In this paper, we intended to investigate the availability of CT scan and treatment planning computer in 700 cancer patients who have undergone radiation therapy at the division of radiation therapy, Kangnam St. Mary's Hospital, Catholic Medical College between Mar. 1983 and Dec. 1985. The result were as follow; 1. Of 700 irradiated cancer patients, 342 patients ($48.9\%$) were performed CT scan prior to radiation therapy. 2. The distribution of lesions in 342 patients having CT scans was like this; CNS (83 of 104 patients, $79.8\%$), abdomen (44 of 76 patients, $57.9\%$), pelvis (100 of 188 patients, $53.2\%$) etc. in order. 3. The treatment planning computer were used in 280 cancer patients ($40\%$). 4. Of the 280 cancer patients using treatment planning computer, 167 patients ($59.6\%$) applied diagnostic CT scan and remaining 113 patients ($40.4\%$) were made body contour to be used for radiation therapy planning by the treatment planning computer. Authors also made some magnification devices used for small multiformat CT images to magnify into life size, consisting of overhead projector (3M) I.V. stand and mirror. These enabled us to make less errors in tracing the small-sized CT images during input of the anatomical data into the treatment planning computer.

This paper is the sequel to 'A study on research methodology of the quoted verses in Dong-uisusebowon(1)'. In this paper, a more detailed discussion on the Shanghanlun lines quoted in the Dong-uisusebowon were carried out based on the aforementioned conclusion, using tao-ren-cheng-qi-tang(桃仁承氣湯) and di-dang-tang(抵當湯) lines related to the tip disease pattern of the So-eum constitution. First in the case of tao-ren-cheng-qi-tang lines, the treatment instructions tell us to use the formula after treating the tip, only when there are root symptoms left. However, in the Dong-uisusebowon, Lee instructed to use tao-ren-cheng-qi-tang when tip symptoms were present. Also, in the di-dang-tang lines, symptoms related to kuang (狂) and stiffening of the lower abdomen which are main manifestations of xu-xue(蓄血) pattern are modified from the Shanghanlun version. The reason behind the difference in contents between the Dong-uisusebowon and Shanghanlun in the mentioned lines is because the lines were already modified in the Dong-uibogam. Heo Jun modified the tao-ren-cheng-qi-tang lines to maintain coherence with the contents of di-dang-tang used in the xu-xue(蓄血) pattern. Another reason for Heo's modification of the di-dang-tang lines is to correct the incoherence of symptoms listed according to the difference in severity of the two di-dang-tang disease patterns. As we can see, Heo modified these parts in the Dong-uibogam based on logical reasons, which enabled Lee to avoid logical contradiction and suggest the So-eum tip disease pattern naturally, by referencing the lines as quoted in the Dong-uibogam.

Generally, it is known that the spleen accompanied by liver cirrhosis is hypertrophied or enlarged. We examined the wave pattern of the spleen by using abdominal CT images of a patient with liver cirrhosis, and found that they are different from those of a person with a normal liver In the abdominal CT image of the patient with liver cirrhosis, there is a deep wave part on the left side of the spleen. In the case of the normal liver, there are waves on the left side, but they aren't deep. Therefore, the total area of waving parts of the spleen with liver cirrhosis is found to be greater than that of the spleen with the normal liver. Moreover, when examining circularity by abstracting the waves of the spleen from the image iO liver cirrhosis, we found they are more circular than those of the spleen accompanied by a normal liver. This paper suggests an automatic method to diagnose splenic enlargement by using the wave pattern of the spleen in abdominal CT images on the basis of the two principles. It tells us that we can judge if the abdomen has a focal splenic enlargement automatically, without the manual test of the size of spleen, only with the shape of spleen.

Purpose: The pedicle of transverse rectus abdominis myocutaneous(TRAM) flap and deep inferior epigastric arterial perforator flap is deep inferior epigastic artery (DIEA) and accurate anatomic knowledge about perforator of DIEA is very important for the elevation of these flap. The authors investigated a detailed vascular network of perforator of DIEA in Koreans. Methods: 24 fresh cadavers were studied. Among them, 15 were examined based on the plain X-ray examination for the distribution and location of perforator of DIEA. And 9 fresh cadavers were examined based on the 3-dimensional computed tomography(CT) study for the distance between ending point of perforator of DIEA and mother artery, the distance between most medial mother artery and midline, the distance between most lateral mother artery and midline, and the running type of perforators of DIEA. Results: Based on the plain X-ray examination, suitable(external diameter$${\geq_-}0.5mm$$) perforators of DIEA are located between the level of umbilicus and 8 cm below it. Based on the 3D-CT study, average distance between the ending point of perforator of DIEA and the mother artery is 30.26 mm on the left, 28.62 mm on the right, respectively. The average distance between most medial mother artery and midline is 17.13 mm on the left, 15.76 mm on the right, respectively. The average distance between most lateral mother artery and midline is 56.31 mm on the left, 50.90 mm on the right, respectively. The main running course of suitable perforators of DIEA is type a, which is a direct musculocutaneous perforator vessel from main vascular axis passing outward to join the subdermal plexus, directly. Conclusion: 3-dimensional computed tomography study as well as plain X-ray examination provided more accurate and detail informations about perforators of DIEA in Koreans. These informations will help us understand the detailed vascular anatomy and operation with ease and safe in the lower abdomen of Koreans.

This thesis is written about the causes, the processes and the treatments of edema. It consists of 31 chapters. Covering 11 chapters, there are prescriptions and constructions. When one of the organs fails to work metabolizing water, you can have edema. It is the result of the accumulation of excess fluid under the skin. Edema most commonly occurs in the head facial, the palpebral portion, the feet and legs or all the body. Sometimes it is accompanied with ascites. There are three classifications in the thesis. First, according to the cause and the symptom of disease, it is divided into 5 types. Type 1. The swelling caused by the disorder of the lungs from the troubling wind. Type 2. The swelling caused by the weak spleen. Type 3. The swelling caused by abnormal condition between the kidneys and the lungs. Type 4. The swelling in abdomen caused by the weak kidneys. Type 5. The swelling (Yellow sweat) caused by the heat inside body as water outside. Second, the swelling and the abnormal symptom of five viscera. Third, the swelling accompanied with menstruation in female and with chilliness. In short, the original textbook is showed that the treatment of edema focuses on the cause and the region of fluid accumulation. When the swelling is in the upper body or the cause of diseaseis outside, the useless humidity can be expelled through sweating. On the other hand, when the swelling is in the lower body or the cause of disease is inside, it is pushed out by urination. In this book, the author presents further treatments. And these treatments are often cited by doctors after ages. Even one of them suggested that the swelling be divided by cosmic dual forces. In spite of many researches, it is too complicate for us to understand the writer’s intend. For that reason, comparing with other medical books and referring to guides explained by doctors, I have studied the textbook to help understand.

Thirty three members of the Korean Association of Pediatric Surgeons were surveyed to determine the clinical manifestations and current management of infantile hypertrophic pyloric stenosis (IHPS). The members completed a registration form and a questionnaire that indicated their treatment preferences for patients treated during 1996. The response rate was 84.8 %, and 23 institutions participated. Three hundred and sixty-three cases of IHPS were analysed. The male to female ratio was 5.15: 1. The presenting symptoms were nonbilious vomiting in 363 cases(100 %), palpable mass in the upper abdomen in 200 cases (55.1 %) and visible peristaltic waves in 67 cases(18.5 %). Fluid therapy was done in 161 cases(44.4 %) for preoperative preparation. Twenty patients(5.5 %) were premature. There were 27 low birth weight babies(7.7 %). The onset of symptoms ranged from 1 to 14 weeks of age with a peak occurrence at 2 to 4 weeks of age. Two hundred and thirty-six cases(66.6 %) presented within 4 weeks of age. There was one set of male twins and a family history of twins. The modes of feedings were: breast feeding; 69 cases(24.5 %), formula feeding; 176 cases(62.4 %) and mixed feeding; 37 cases(13.1 %). The preferred diagnostic modalities were ultrasonography (US) 229 cases(63.1 %), UGI series 27 cases(7.4%) and US and UGI series combined 86 cases(23.7 %). Only 21 cases(5.8 %) were operated on without imaging study, ie. with positive physical finding. Perforation of the mucosa during pyloromytomy occurred in 5 cases. All were treated successfully with primary closure. Persistent vomiting over 2 weeks after operation were reported in 5 cases. Three wound infections, one aspiration pneumonia and one postoperative bleeding were reported. There was no mortality in 363 cases.
