Two hundreds fifty seven cases of normal mammogram were analysis for classification of types of breasts.Ranging from 20 to 79 years of age, mean age was 45 years. Two projections, craniocaudal & mediolateral, were used. Age, nutrient condition, familial tendency and hormonal factors influence to breats hisologically. Normalbreats were classified into the standard (9.75%), ductal (71.7%), glandular (6.2%) and atrophic (12.4%) types.Ductal type was further subclassified into intraductal, periductal and mixed types. Atrophic type was susbdividedinto fibrous and fatty, Standard type was observed in younger women, instead of atrophic type was seen in olderage group, especially after menopause. Periductal type was most common (65.4%), Glandular type was mostly intwenty to thirty year group. According to increase of age, gladular or ductal type transformed into atrophic type.

BACKGROUND: Left ventricular hypertrophy is an independent risk factor for coronary artery disease, hypertension or other cardiovasular diseases, and normal health person due to cardiac arrhythmia or coronary microcirculatory insufficiency. According to development of echocardiography, left ventricular mass and the patterns of left ventricular hypertrophy can be measured. Therefore, we tried to classify the left ventricular hypertrophy in coronary artery disease and to differentiate cardiac function and severity of coronary artery disease in these groups. METHOD: From September 1993 to August 1995, in 44 cases(23 males, 21 females) without hypertension with normal coronary angiography and 84 cases(62 males, 22 females) without hypertension with coronary artery disease on coronary angiography were compared by two-dimensional, M-mode, and Doppler echocardiography. RESULTS: In normal control group, mean age was 51+/-11years, and in coronary artery disease group, mean age was 58+/-10years. Atherosclerotic risk factors showed no significant differences in each groups. LVH patterns in normal control group were 31 cases(70%) of normal left ventricle, 6 cases(14%) concentric remodelling, 2 cases(5%) concentric hypertrophy, and 5 cases(11%) eccentric hypertrophy. In coronary artery disease group, 30 cases(36%) were normal left ventricle, 17 cases(20%) concentric remodelling, 14 cases(17%) concentric hypertrophy, and 23 cases(27%) eccentric hypertrophy. CONCLUSIONS: In this study, concentric and eccentric hypertrophy were more common in coronary artery disease group than normal control group. And comparing to one vessel disease grroup, multi-vessel disease group had more common concentric and eccentric hypertrophy. This result were considered that left ventricular concentric hypertrophy may induce coronary heart disease because more oxygen demand required and fixed coronary circulation, and essentric hypertrophy was due to post-infarct left ventricular remodelling and wall thinning.

The effect of 0.25% and 0.5% Timolol on intraocular pressure and concentration in aqueous humor was studied after topical instillation in the white rabbit. The intraocular pressure was measured with pneuma tonometer and the Timolol concentration in aqueous humor was measured with High Preformance Liquid Chromatograph after fine needle aspiration of aqueous humor at various time intervals. The results were as follows; 1. The percentage reduction of intraocular pressure increased with time and reached a peak after 3 hours. 2. The concentration of Timolol in aqueous humor increased with time and reached a peak after 3 hours. 3. There was close correlation between intraocular pressure and Timolol concentration in aqueous humor.

Cryoglobulinernia occurs in about 5% of the cases of multiple myeloma. The most common finding in patient with cryoglobulinemia is ulceraticn that oceurs about ankle, hands, and occasionally the ears, upon prolonged exposue to cold. A 59-year old male had had 5 years of pain in his ears. There were black or dark brown colored ischemic ulcerations on his both helix. He also had mottled purpuric patches on his both ankles. A test for cryoglobulinema was positive. X-ray examination of the skull showed multiple punched but lesions. The bone marrow study revealed myeloma cell infiltration.

Toxoplasma gondii tachyzoites were isolated from the blood of an ocular patient, and have been successfully passaged in the laboratory, for over a year, by peritoneal inoculation in mice. The isolated parasite was designated the Korean Isolate-1 (KI-1) and its characteristics were compared with those of the RH strain, a wellknown virulent strain originating from a child who suffered from encephalitis. The morphology, pathogenicity, infectivity and cell culture characteristics of the KI-1 were similar to those of the RH strain. Both RH and KI-1 antigens were detected by an anti-T. gondii monoclonal antibody (mAb), Tg563, against the major surface protein SAG1 (30 kDa), whereas no reaction was observed against an anti-Neospora caninum mAb, 12B4. The KI-1 was confirmed as an isolate of T. gondii. A long-term laboratory maintenance and characterization of a local T. gondii isolate is reported for the first time in the Republic of Korea.

Adherence of Candida albicans(C. albicans) to the surface of a denture is believed to be an initial and essential step in the formation of denture-induced stomatitis. Previous studies have provided enormous infomation on the relationship between composition of palatine gland/parotid saliva and upper denture stomatitis. Relatively little information is available on the correlation between lower denture stomatitis and sublingual-submandibular(SLSM) saliva. The plaque samples were collected from the two sites(100mm2) on the inner surface of lower partial denture corresponding to the stomatitis and healthy region of the lower partial dentures of 12 denture stomatitis patients and 6 normal persons who wore lower partial dentures. The samples were plated to isolate C. albicans on a selective Saboraud's dextrose agar plate and the isolates were identified by germ tube test and gram staining. The subjects were divided into group I (stomatitis with C. albican), group II (lesion without C. albicans), group III (no lesion but C. albicans), and group IV (normal and healthy denture wearer). Individual SLSM saliva (20microgram of protein) was analyzed by SDS-PAGE(SDS-poly-acrylamide gel electrophoresis) with Coomassie brilliant blue and PAS(Periodic Acid Schiff) staining. The salivary proteins separated in the polyacryamide gels were subjected to immunoblot analysis using anti-lactoferrin, anti-sIgA, and anti-secretory component of sIgA. In this study using custom made acrylic denture resin beads(5mm in diameter) coated with stimulated individual SLSM saliva, the binding ability of individual C. albicans strains to the beads was observed. Levels of C. albicans adhered to the acrylic resin beads were determined by measuring the optical density of the bound C. albicans to the beads at 580nm. The results showed that a higher number of C. albicans was observed in the lesion site than health site. The saliva of group I contained more high molecular weight glycoprotein(mucin, MG1) as compared to group II, III, and IV. And lactoferrin and sIgA affected to the binding ability of C. albicans to acylic resin beads. Binding ability of individual C. albicans to the acrylic resin coated with respective individual saliva was found to be greater in group I than the other 3 groups. And when bound cells of C. albicans isolated from individual subject #2 to the saliva coated beads were used, binding ability of subject #2 saliva coated beads was founed to be greater than the other subjects. These results suggested that denture induced stomatitis is related to individual patient's salivary protein composition, especially MG-1. Future studies will be directed toward saliva examination of patients who have general disease and analysis of pellicles formed on prosthesis with respect to oral disease.

Journal of the Korean Society for Vascular Surgery 1999;15(2):253-260
PURPOSE & METHOD: To evaluate clinical pattern and operative outcome of the ischemic lower extremity, 142 patients who were admitted to Yeungnam University Hospital between January 1996 to December 1998 were analyzed. RESULTS: The patients were 125 males and 17 females ranging from 21 to 88 years of age. The mean age was 59, with the highest incidence among people in their 60s, followed by those in their 70s and then in their 50s. The causes of arterial occlusive disease were artherosclerotic obliterans (ASO) in 87 cases (61.2%), thromboangitis obliterans (TAO) in 44 cases (30.9%), thromboembolism in 10 cases and superficial femoral aneurysm in 1 case. Associated diseases in ASO were hypertension in 37 cases (42.5%), diabetes mellitus in 17 cases (30.9%), cardiac disease in 24 cases (27.5%) and cerebrovascular disease in 7 cases (8.0%). History of smoking was noted in 77.4% of the cases. The major arterial occlusive site of ASO were femoral artery in 36 cases (41.3%), aortoiliac artery in 26 cases (29.8%), iliofemoral artery in 9 cases (10.3%), popliteal artery in 5 cases (5.7%), tibial artery in 6 cases (6.8%) and multi-level occlusion in 5 cases (5.7%). The major arterial occlusive site of TAO were tibial artery in 35 cases (79.5%), pedal artery in 8 cases (18.1%) and popliteal artery in 1 case. According to the Fontaine classification of clinical symptoms, the distribution was as follows: Grade 0 0 case, Grade I 48 cases (33.8%), Grade II 46 cases (32.3%) and Grade III 48 cases (33.8%). The operative procedures of arterial occlusive disease were bypass graft operation in 72 cases, thromboembolectomy in 12 cases, endarterectomy in 2 cases and percutaneous transluminal angioplasty (PTA) was performed in 9 cases. Arterial bypass operation with autogenous or artificial prosthesis were done in 72 cases, which included aortobifemoral or aortobipopliteal bypass in 12 cases, iliofemoral bypass in 5 cases, femoropopliteal bypass in 26 cases, femorotibial bypass in 5 cases, popliteotibial bypass in 8 cases. axillobifemoral bypass in 4 cases and femorofemoral bypass in 12 cases. In over 90% of the operative cases, the early outcome was good with 3+ to 2+ rating according to Rutherford criteria. Mortality for 114 cases was 2.6% (3 cases), including 2 resulting from associated cardiac condition and 1 resulting from ARDS. CONCLUSION: Strategies for successful revascularization and long term patency may be made by consideration of the extent of diseases, associated diseases, clinical symptoms and status of distal perfusion.

We report here on a case of popliteal aneurysm and rupture that occurred over a 10-day period and this was all secondary to salmonella infection. Computed tomography (CT) angiography of the extremity that was performed before and after aneurysmal rupture showed the aneurysm's rapid evolution to rupture over a short period of time. We also review the pathogenesis, clinical presentation, diagnostic approach and management of salmonella aneurysms.
