Background and Objectives : Recently, the incidence of breast cancer is gradually increasing in korea. Many patients visit the hospital with a fear of breast cancer, if she had the pain in her breast. But Breast pain is not a cardinal sign of breast cancer. Only 7% of patient in breast cancer has breast pain. Materials and Method : To know the clinical effects of gamma-linolenic acid(GLA), we analyzed the medical records of 55 cases with breast pain, who visited the outpatient clinic of Chosun university hospital, between July of 1999 to December of 1999. Of the 55cases of breast pain, we analyzed 26 cases of patient with breast pain who was treated with GLA for 2 month and we excluded patients of breast pain who had breast mass or were treated with other drug. Results : 2 Patients we are dropped out because nausea and vomiting were developed, 4 Patient with breast pain were treated with GLA for 1 month, and relieved completely from mastalgia and 8 patients with breast pain were treated with GLA for 2 months and breast pain was relieved completelys. 4 patient had treatment for 2 months, were relieved slightly. But 8 patients with breast pain didn't reveal the relief of symptom after the intake of GLA. Conclusion : We conclude that GLA could be considered a first line drug in patients with mastalgia.

Purpose : The purpose of the experiment was to evaluating the diagnostic ability of dental caries detection using digital subtraction in the artificial caries activity model. Materials and Methods : Digital radiographies of five teeth with 8 proximal surfaces were obtained by CCD sensor (Kodak RVG 6100 using a size #2). The digital radiographic images and subtraction images from artificial proximal caries were examined and interpreted. In this study, we proposed novel caries detection method which could diagnose the dental proximal caries from single digital radiographic image. Results : In artificial caries activity model, the range of lesional depth was 572-1,374 μm and the range of lesional area was 36.95-138.52mm². The lesional depth and the area were significantly increased with demineralization time (p<0.001). Furthermore, the proximal caries detection using digital subtraction radiography showed high detection rate compared to the proximal caries examination using simple digital radiograph. Conclusion : The results demonstrated that the digital subtraction radiography from single radiographic image of artificial caries was highly efficient in the detection of dental caries compared to the data from simple digital radiograph.

Hypwelipiswmia is commonly observed in the diabetics, especially with cardiovascular complications. We studied lipid profiles and cardiovascular complication in the 191 adult onset DM patients. The results are as follows: 1. The age distribution was from 24 years old to 82 years old. Male patients were 99 persons, famale patients were 92 persons. The mean disease duration was less than 2 years in the 77 patients, more than 5 years in the 79 patients. 2. Upon the classification between sexes, the mean age was 55±1(SEM) years in the male group, 53±1(SEM) years in the female group. The mean disease durtion was 6.4±1(SEM) years in the female group, longer in the male group (P<0.05). The triglyceride level was 210±16(SEM)㎎% in the male group, 214±13(SEM)㎎% in the female group. The fasting blood sugar level was 147±6(SEM)㎎/dl in the male group, 158±8(SEM)㎎/dl n the female group. The cholesterol level was 229±5(SEM)㎎/dl in the male group, 248±5(SEM)㎎/dl in the female group, higher in the female group (P<0.05). 3. The cardiovascurlar complicatioin (Hypertension, Myocardial infarction, Myocardial ischemia, Angina, Gangrene, Proliferative retinopathy) were present in the 60 patients from 191 patients. Hypertension was present in the 48 patients, and the most prevalent. The mean age and carrdiovascular complication were higher in the more than 5 years of mean disease duration group(mean age 57.99±1.14(SEM)㎎ year) than less than 5 years group(mean age 52.12±0.10(SEM)㎎ year) (P<0.001, P<0.01). 4. The mean disease duration (7.40±1.01(SEM) years), mean triglyceride levels(271±1.01(SEM)㎎%), and mean cholestrerol levels( 257±8㎎.dl) in the cardiovascularly complicated group were higher than those of non-complicated group (P<0.01). 5. The triglycerdie level was high in the obese group (230±14SEM㎎%) than non-obese group (184±15SEM㎎%) (P<0.05). The obese patients were more prevalent in the female group than male group significantly. 6. Considering obesity and cardiovascular complications, the triglyceride value was higher in the obese complicated group(300±30SEM㎎%) than obese non-complicated (197±14SEM㎎ %) or non-obese non-complicated (168±13SEM㎎ %) group (P<0.001). The cholesterol level was higher in the obese complicated group (267±10SEM㎎/dl) than obese non-complicated (230±5SEM㎎/dl) or non-obese non-complicated group(229±7SEM㎎/dl) (P<0.05). 7. Classifying upon insulin response pattern, the obese patients were found in the response pattern, low response pattern, flat type pattern(no response pattern) in the decreasing number of order (P<0.01). The cardiovascular complications were found in the low response group, response group, and flat type pattern (no response) in the decreasing number of order ( P<0.05). The combined cases of obesity and cardiovascular complications were found in the low response group, response group and flat type group(no response) pattern in the decreasing number of order (P<0.01). The mean disease duration was longer in the flat type group (no response) (4.48±0.6SEM years) than the response group(2.43±0.90SEM years) (P<0.05). The mean triglyceride value was higher in the response group (267.38±154.75SEM㎎%) than the flat type(no response group) (198.35±154.05SD㎎%) (P<0.05). So, we conclude that in the NIDDM, obesity control(die control, ideal body weight mainterice, and hyperlipidemia control) is essential for better DM control and cardiovascular complication control.

The enzyme, squalene synthase, represents a branch point in the isoprenoid pathway capable of diverting carbon flow specifically to the biosynthesis of phytosterol and Triterpenoid. Transgenic Eleutherococcus senticosus plants were prepared by introducing the genes for squalene synthase derived from Panax ginseng (PgSS1), hygromycin phosphotransferase (HPT) and green fluorescent protein (GFP) through Agrobacterium-mediated transformation. Establishment of transgenic plantlets were confirmed by the presence of PgSS1 and HPT bands in the genomic DNA preparation using a PCR method and a Southern blotting. In addition, expression of the introduced GFP DNA was confirmed by observing green fluorescence of GFP from the embroyos. In the in vitro analysis of the PgSS1 enzymatic activities the transgenic plants showed to have 1.5 to 3 times higher than wild type plant, indicating that the PgSS1 genes was well over-expressed in the transgenic plants. Especially the PgSS1 acivities of embroyogenic cell was 120 times higher than those of plantlet.

The Actinomyces species are normal flora of oral cavity and upper intestine characterized as gram-positive, non-spore-forming anaerobic or mjcroaerophilic rods. Actinomycosis is a chronic suppurative and granulomatous disease characterized by abscess, sinus, abundant granulation and mass. The appendix is the commonly involved site among abdominal actinomycosis. Abdominal actinomycosis is often difficult to diagnose before operation because of no reliable clinical features and infrequency of the disease. We report two cases of abdominal actinomycosis which were manifested as acute appendicitis. Those were detected Incidentally tv the pathologist after routine appendectomy. Both patients were successfully treated with appendectomy followed by proper antibiotics use.

An increasing number of genome sequencing projects results in explosive growth of whole genome sequences. Furthermore the number of studies on the functions of individual genes has also been rapidly increased. However on-memory algorithms are not applicable to the analysis of whole genome sequences, since the size of individual whole gene a ranges from several million base pairs to hundreds billion base pairs. In order to effectively manipulate the huge sequence data, it is necessary to use the indexed data structure for external memory. In this paper, we introduce the development and application of the workbench for the analysis and visualization of whole genome sequences using string B-tree that is suitable for the analysis of huge data. This system consists of two main parts, the analysis query part and the visualization part. The query system supports various transactions such as pattern matching, k-occurrence, and k-mer analysis. The visualization system helps biologists to easily understand whole genome structure and specificity by various kinds of visualization such as whole genome sequence viewer, annotation viewer, CGR (Chaos Game Representation) viewer, k-mer viewer, RWP (Random Walk Plot) viewer, and map viewer. We can find the relationships among organisms, support gene prediction in a genome, and study the function of junk DNA using our workbench. In this paper, we apply our workbench to investigating specific sequence such as avoided sequence, common sequence, and classifiable sequence.

Objectives : The purpose of this study was to test the reliability and validity of the Korean translation of Gambling Symptom Rating Scale (KG-SAS). Methods : Using self-report sampling, we eventually included 231 subjects and analysed 70 subjects. These subjects were tested for KG-SAS and the Korean version of Barratt Impulsiveness Scale (BIS). Results : In the reliability test, Cronbach's alpha coefficient was .913 which provided the evidence for the internal consistency. Content validity was assessed with factor analysis and two factors were extracted. Compared with the original scale, both scales embody the same theoretical conceptualization. To assess the validity of the KG-SAS, correlation coefficient was calculated between the KG-SAS and the Korean version of BIS. We got the result that there was a correlation between the KG-SAS and the Korean version of BIS (p<0.01). Conclusion : The results of the present study support that the KG-SAS is a reliable and valid scale for evaluating Pathological gambling symptom assessment. Based on the results, this study suggests that KG-SAS would be a promising measurement to treat and study pathological gambling.
