Medical images wit high resolution are coded to be archived communicated in PACS. In this pater, we have studied on coding of Cardio-Angiography. Our coding technique is method is Subband-Vector Quantization. This technique is irreversible coding method. This technique's objects are removing blocking artifact and edge degradation, adapting for drastic image change because of dye injection, and fast decoding, We achieved good results for Cardio-Angiography data, but the study on more sophisticated motion estimation techniques and VQ techniques must be performed.

We observed a case of tuberculosis cutis orificialis, which occurred in 50 year-old man. He had been suffered from single markedly inflamed, erythematous painful ulcer, covered by dirty brown pseudomembranous material, around anus for 3 months. The laboratory findings (CBC, routine urinalysis, stool ova and parasite with occult blood) are within normal limits except elevated ESR (52mm/hr.). Staphyloeoccus aureus and proteus are observed on wound culture, and many AFB are seen on scrapings of wound but not on sputum for 3 times. Unfortunately culture was not done. Tuberculin skin test revealed strong reaction (36mm/hr.). Chest PA and small bowel series showed far advanced pulmonary tuberculosis and intestinal tuberculosis on ileocecal area. But the findings of upper gastro-intestinal series and barium enema are within normal limits. Histopathologic findings of skin lesion showed tuberculous and tuberculoid granuloma in the deep dermis and subcutaneous tissue.

Treatment with INH, myambutol and rifampin resulted in some improvment on the chest and considerable improvement on the skin and intestine within 6 months.

BACKGROUND: Estrogen deficiency accelerates loss of bone mass and changes lipid profile in the postmenopausal women, so that the osteoporosis and astherosclerosis were developed. But it has not enough studies including the premenopausal women. So we have investigated about the differences of body mass index(BMI), lipid profile and bone mineral density (BMD) with pre- and postmenopausal women. METHODS: We have evaluated 201 premenopausal women and 322 postmenopausal women out of total 651 who had visited Health Screening Center in the hospital of Eul-Ji Medical College from November, 1995 to July, 1996. RESULTS: The mean age of total subjects, premenopausal women, postmenopausal women were 51.9, 43.9, 56.8 years, respectively. The mean period after menopause was 8.1 years. Significant difference was seen in BMI, lipid profile and BMD according to age and menopause(P<0.01). BMI was related to lipid profile(P<0.01), but not to BMD(P>0.1). In postmenopausal women BMI, BMD and lipid profile were related to postmenopausal period (P<0.05). In viewing their correlations BMD had strong adverse correlations with factors such as age, menopause, and postmenopausal period. Lipid profile had weak positive correlations with factors such as age, menopause, BMI(P<0.001). CONCLUSIONS: The lipid profile are related to factors such as age, BMI, menopause, and postmenopausal period. The BMD is related to above factors except BMI. Prospective study is needed to evaluate the influence of estrogen on BMD and lipid metabolism. Thus, it helps to the prevention and treatment of the osteoporosis and hyperlipidemia in the postmenopausal women.

Breast cancer is one of the leading causes of death attributable to cancer in women. In view of the limitations of conventional predictable factors of the breast cancer, additional second-generation parameters would be valuable in selecting the patients who would be most likely to be beneficial from adjuvant therapy and breast reconstruction. The author investigated the HER2/neu gene amplification and the number of chromosome 17 in 39 cases of paraffin embedded breast cancer tissues, 20 cases without lymph node metastasis and 19 cases with lymph node metastasis, using fluorescent in situ hybridization(FISH) and compared the results with HER2/neu and p 53 protein expression detected by immunohistochemical method. Eleven cases fibroadenoma were used as benign tumor control. Numerical aberrations of chromosome 17 were found in 17 out 39 breast cancer cases (44%)(monosomy in 10 cases, 26%; trisomy in 3 cases, 8%; tetrasomy in 3 cases, 8%; polysomy in 1 case ,3%), and the frequency of each type aberration was not significantly different between the negative and positive groups in lymph node metastasis. Monosomy of chromosome 17 was found in 2 out of 11(12%) fibroadenoma cases. HER2/neu gene amplification was found in 8 out of 39 cases (19%) and other 2 cases revealed HER2/neu gene amplification in lymph node metastatic tumor only, not in original tumor. Fourteen out of 19 cases of breast cancer with lymph metastasis showed HER2/neu protein expression both in original and metastatic tumors. All of the six cases showing HER2/neu gene amplification in original and/or metastatic tumor revealed HER2/neu protein expression. The frequency of HER2/neu gene amplification in the 39 breast cancer cases was not different between metastatic and non-metastatic groups(p= 0.284). However, HER2/neu protein expression was increased significantly in the metastatic group(p=0.028). None of the 11 fibroadenoma cases revealed HER2/neu gene amplification or HER2/ neu protein expression. Nine out of 19 cases of breast cancer with lymph node metastasis showed p 53 protein accumulation in original tumor(47%), but 3 of them revealed p 53 protein accumulation only in original tumor. The frequency of p 53 protein accumulation was not significantly different between metastatic and non-metastatic groups. None of the 11 fibroadenoma cases revealed p 53 protein accumulation. In conclusion, there are no differences between the lymph node metastatic group and non-metastatic groups in numerical aberrations of the chromosome 17 , amplification of the HER2/neu gene expression and accumulation of the p 53 protein in breast cancer. However, the HER2/neu protein expression was increased significantly in lymph node metastatic group, so it could be one of the predictors of the metastasis in breast cancer.
