PURPOSE: This cross-sectional study was designed to identify anger-expression typesof adolescent women and investigate the relation between the identified anger-expression types and their problem behaviors and health status. METHOD: One hundred ninety nine high school freshmen were recruited from September to November, 2003. Data wasanalyzed using descriptive statistics, cluster analysis, chi-square-test, ANOVA, and Duncan's multiple comparison test. RESULT: Three anger-expression types in adolescent women were found; Anger-out/in, Anger-control/in, and Anger- control type. Adolescent women with frequently using the anger-out/in type and with higher state anger reported more delinquent behaviors, more health risk behaviors, and higher psychosomatic symptoms. However, adolescent women with lower state anger and frequently using the anger-control type reported more depression scores. CONCLUSION: There is a need to further clarify the relationship between anger-expression typesand depression in adolescent women. The findings suggest the necessity of a development of the program for lowering the anger level and controlling the unfavorable anger expression types such as the anger-out in.

PURPOSE: This study was designed to investigate the effects of polyamines on rabbit seminal vesicular contractility. MATERIALS AND METHODS: The polyamines; putrescine, spermidine and spermine, were added to deepithelized and precontracted seminal vesicle strips, with either 10 4M norepinephrine (NE), 10 4M acetylcholine (ACh) or 70mM KCl, in organ chambers to obtain cumulative concentration response curves. A whole cell mode patch clamp study was also performed to observe the effects of the polyamines on the L-type calcium channel activities. RESULTS: The polyamines elicited concentration-dependent relaxations of the precontracted strips with the NE, ACh and KCl. The spermine showed the most potent relaxation response. Both extracellular and intracellular application of the spermine decreased the L-type calcium channel currents. CONCLUSIONS: Spermine more potently inhibited the seminal vesicle contraction than putrescine or spermidine, which suggests the polyamines may play a role in maintaining the basal tonicity of seminal vesicle in a flaccid state. The spermine-induced relaxation response seems to be related with an inhibition of the L-type calcium channel activities.

BACKGROUND: The cyclin D1 gene is one of the most frequently amplified chromosomal regions(11ql3) in human carcinomas. In laryngeal and head and neck carcinomas, its overexpression has been shown to be associated with advanced local invasion and presence of lymph node metastases. Cyclin D1 may therefore play a key role in cell growth regulation and tumorigenesis. Lung cancer is a worldwide problem and in many contries it is the most lethal malignancy. As relapse is frequent after resection of early stage non-small cell lung cancer, there is an urgent need to define prognostic factors. PURPOSE: This study was undertaken to evaluate the prognostic value of the cyclin D1, that is one the G1 cyclins which control cell cycle progression by allowing G1 to S phase transition, on the patients in radically resected non-small cell lung cancer. METHOD: Total Si cases of formalin-fixed paraffin-embedded blocks from resected primary non-small cell 11mg cancer from January 1., 1983 to July 31, 1995 at Hanyang University Hospital were available for both clinical follow-up and immunohistochemical staining using monoclonal antibodies for cyclin D1. RESULTS: The histologic classification of the tumor was based on WHO criteria, and the specimens included 45 squamous cell carcinomas, 25 adenocarcinomas and 11 large cell carcinomas. Cyclin D1 overexpression was noted in 26 cases of 81 cases tested (30.9%). Cyclin D1 expression was not significantly associated with cell types of the tumor, pathological staging and the size of the tumor. But cyclin D1 overexpression was significantly correlated with positive lymph node metastasis(p=0.035). The mean survival duration was 22.76+/-3.50 months in cyclin D1 positive group and 45.38 +/- 5.64 months in cyclin D1 negative group. There was a nearly significant difference in overall survival Between cyclin D1 positive and negative groups(p=0.0515) in radically resected non-small cell lung cancer. CONCLUISON: Based on this study, cyclin D1 overexpressiom appears at important poor prognostic indicator in non-small cell lung cancer and may have diagnostic and prognostic importance in the treatment of resectable non-small cell lung cancer.

The aim of periodontal treatments is the complete restoration of the structure and function of damaged periodontal tissues. Although it is very difficult to attain this goal, recent advances in periodontal wound healing concepts encourage hope reaching it. Safflower seeds has been used for the treatment of blood stasis, bone fracture and osteoporosis in traditional Korean medicine. The purpose of this study is to examine effects of the isolated extracts from Safflower seeds on mineralization of periodontal ligament cells and osteoblastic cells. Periodontal ligament cells were primarily obtained from a extracted premolars with non-periodontal diseases. Osteoblastic cells were obtained from calvariae of a fetal rat. Cells were cultured with DMEM at 37degrees C with 5% CO2 in 100% humidity incubator. Safflower seeds were isolated into the H2O layer and the butanol layer. MTT assay and alkaline phosphatase(ALP) level were examined. Also the number of bone calcification nodules were evaluated. The obtained results were as follows: 1. The cellular activity of periodontal ligament cells was significantly increased in 10(-3)g/ml, 10(-6)g/ml of both H2O layer and butanol layer of Safflower seeds. 2. The cellular activity of osteoblastic cells was significantly increased in 10(-3)g/ml, 10(-6)g/ml of H2O layer of Safflower seeds. 3. ALP level of periodontal ligament cells was significantly increased in 10-3g/ml of both H2O layer and butanol layer of Safflower seeds. 4. ALP level of osteoblastic cells was significantly increased in 10(-3)g/ml, 10(-6)g/ml of H2O layer and especilly more increaton was showed in 10(-3)g/ml of H2O layer. 5. Calcification nodules of periodontal ligament cells slightly increased in 10(-3)g/ml of both H2O layer and butanol layer of Safflower seeds. 6. Calcification nodules of osteoblastic cells slightly increased in 10(-3)g/ml, 10(-6)g/ ml of H2O layer of Safflower seeds. These results indicate that H2O layer and butanol layer of the isolated extracts from Safflower seeds has excellent effects on mineralization of periodontal cells and osteoblastic cells.

PURPOSE: To analyze the characteristics of CT and MRI findings of facial nerve schwannoma in ten patients. MATERIALS AND METHODS: Ten patients with pathologically confirmed facial nerve schwannoma, underwent physical and radiologic examination. The latter involved MRI in all ten and CT scanning in six. We analyzed the location (epicenter), extent and number of involved segments of tumors, tumor morphology, and changes in adjacent bony structures. RESULTS: The major symptoms of facial nerve schwannoma were facial nerve paralysis in seven cases and hearing loss in six. Epicenters were detected at the intraparotid portion in five cases, the intracanalicular portion in two, the cisternal portion in one, and the intratemporal portion in two. The segment most frequently involved was the mastoid (n=6), followed by the parotid (n=5), intracanalicular (n=4), cisternal (n=2), the labyrinthine/geniculate ganglion (n=2) and the tympanic segment (n=1). Tumors affected two segments of the facial nerve in eight cases, only one segment in one, and four continuous segments in one. Morphologically, tumors were ice-cream cone shaped in the cisternal segment tumor (1/1), cone shaped in intracanalicular tumors (2/2), oval shaped in geniculate ganglion tumors (1/1), club shaped in intraparotid tumors (5/5) and bead shaped in the diffuse-type tumor (1/1). Changes in adjacent bony structures involved widening of the stylomastoid foramen in intraparotid tumors (5/5), widening of the internal auditary canal in intracanalicular and cisternal tumors (3/3), bony erosion of the geniculate fossa in geniculate ganglion tumors (2/2), and widening of the facial nerve canal in intratemporal and intraparotid tumors (6/6). CONCLUSION: The characteristic location, shape and change in adjacent bony structures revealed by facial schwannomas on CT and MR examination lead to correct diagnosis.

Cerebrovascular disease and coronary heart disease are the first and the fourth common causes of death among adults in Korea. Reported risk factors of one of these diseases may prevent other diseases. Therefore, we tried to compare and discriminate the risk factors of these diseases. We recruited four case groups and four control groups among the inpatients who were admitted to Wonju Christian Hospital from March, 1994 to November, 1995. Four control groups were matched with each of four case groups by age and sex. The number of patients in each of four case and control groups were 106 and 168 for acute myocardial infarction(AMI), 84 and 133 for subarachnoid hemorrhage(SAH), 102 and 148 for intracerebral hemorrhage(ICH), and 91 and 182 for ischemic stroke(IS) respectively. Factors whose levels were significantly higher in AMI and IS than in responding control group(RCG) were education, economic status, and triglyceride. Factors whose levels were significantly lower in hemorrhagic stroke than in RCG were age of menarch, and prothrombin time. The factor whose level was higher in AMI than in RCG was uric acid. The factor whose level was higher in AMI, ICH, and SAH than in RCG was blood sugar. Factors whose levels were significantly higher in all the case groups than in RCG were earlobe crease, Quetelet index, white blood cell count, hemoglobin, hematocrit, and total cholesterol. The list of risk factors were somewhat different among the four diseases, though none of the risk factors to the one disease except prothrombin time acted as a preventive factor to the other diseases. The percent of grouped cases correctly classified was higher in the discrimination of ischemic diseases(AMI and IS) from hemorrhagic diseases(SAH and ICH) than in the discrimination of cerebrovascular disease from AMI. The factors concerned in the discrimination of ischemic diseases from hemorrhagic diseases were prothrombin time, earlobe crease, gender, age uric aci, education, albumin, hemoglobin, the history of taking steroid, total cholesterol, and hematocrit according to the selection order through forward selection.

Several postharvest diseases of table grapes (Vitis vinifera) occur during storage, and gray mold rot is a particularly severe disease because the causal agent, Botrytis cinerea, grows at temperatures as low as 0degrees C. Other postharvest diseases, such as those caused by Penicillium spp. and Aspergillus spp., also often lead to deterioration in the quality of table grapes after harvest. The use of plant essential oils such as thymol and linalool, to reduce postharvest diseases in several kinds of fruits, including table grapes and oranges, has received much attention in European countries. However, to the best of our knowledge there has been no report of the use of thymol fumigation to control gray mold in table grapes in Korea. Thymol (30 microg/mL) and linalool (120 microg/mL) significantly inhibited mycelial growth and conidia germination of B. cinerea. The occurrence rate of gray mold rot of B. cinerea and other unknown fungi was significantly reduced by fumigation with 30 microg/mL thymol in several table grape cultivars, such as Campbell early, Muscat Bailey A, Sheridan, and Geobong. In this study, fumigation with 30 microg/mL thymol, had no influence on the sugar content and hardness of grapes, but reduced fungal infection significantly. This suggests that 30 microg/mL thymol could be utilized to reduce deterioration of grapes due to gray mold and other fungal infections during long-term storage.

Fungal endophytes have been recorded in various plant species with a richness of diversity, and their presence plays an essential role in host plant protection against biotic and abiotic stresses. This study applied the Illumina MiSeq sequencing platform based on the amplification of fungal ribosomal ITS2 region to analyze fungal endophytic communities of two oak species (Quercus mongolica and Q. serrata) with different oak wilt disease susceptibilities in Korea. The results showed a total of 230,768 sequencing reads were obtained and clustered at a 97% similarity threshold into 709 operational taxonomic units (OTUs). The OTUs of Q. serrata were higher than that of Q. mongolica with the number of 617 OTUs and 512 OTUs, respectively. Shannon index also showed that Q. serrata had a significantly higher level of fungal diversity than Q. mongolica. Total of OTUs were assigned into 5 fungal phyla, 17 classes, 60 orders, 133 families, 195 genera, and 280 species. Ascomycota was the dominant phylum with 75.11% relative abundance, followed by Basidiomycota with 5.28%. Leptosillia, Aureobasidium and Acanthostigma were the most abundant genera detected in Q. serrata with the average relative abundance of 2.85, 2.76, and 2.19%, respectively. On the other hand, Peltaster, Cladosporium and Monochaetia were the most common genera detected in Q. mongolica with the average relative abundance of 4.83, 3.03, and 2.87%, respectively. Our results indicated that fungal endophytic communities were significantly different between two oak species and these differences could influence responses of host trees to oak wilt disease caused by Raffaelea quercus-mongolicae.

BACKGROUND AND OBJECTIVES: Pain control is one of the most important factors for the patients that underwent the snoring surgery. This study was performed to investigate the effectiveness of intravenous patient-controlled analgesia (PCA) for postoperative pain control after tonsillectomy with laser resection of palatopharynx. MATERIALS AND METHODS: In this double-blind randomized study, 44 patient were randomly allocated to 2 groups. In the PCA group comprising 32 patients, fentanyl citrate, ketorolac tromethamine and zofran in normal saline solution were administered by PCA equipment. In the control group comprising 12 patients, normal saline solution was given without analgesic drug by PCA equipment. Visual analogue pain score (VAS) was recorded right after surgery and 2, 4, 6, 12, 18, and 24 hours after surgery and satisfaction score was recorded just before discharge from the hospital. RESULTS: VAS was significantly higher in the control group of all time points. Overall satisfaction score was also higher in PCA group than control group. CONCLUSION: The results of this study suggest that intravenous PCA is an effective method for postoperative pain control after tonsillectomy with laser resection of palatopharynx.
