STATEMENT OF PROBLEM: Recently the populations of patients receiving implant surgery are greatly increase for maintaining oral health. PURPOSE: This study was conducted for implanted patients to assess the chewing ability patient satisfaction level and changes in quality of life before and after the implant surgery. MATERIAL AND METHODS: The current study subjected 109 adult patients, older than 20 years of age, who received implant surgery from December, 2006 to October, 2007 at the 6 dental clinics located at Daegu and Ulsan metropolitan cities. Twice of surveys were conducted for the patients before and after receiving the dental implant surgery. RESULTS: As the motivation of receiving implant surgery, 45.9% of the patients selected the surgery for the chance of "chewing function recovery", and "failure of treatment and complications" was found to be the most worrisome at the time of surgery by recording 38.5%. The satisfaction level before the implant surgery scored 30.37, while the score was increased to 45.01 after the surgery by showing a significant difference before and after receiving the surgery (P < .001). Regard on the surgery, 91.8% of the patients responded as "Satisfy", and 89% of the study subjects responded that they have willingness to recommend the surgery to their families and friends. The chewing ability score measured by using the surveys on edible foods, the score before the surgery was 15.24, while the score was increased to 19.11 after the surgery by showing a significant difference before and after receiving the surgery (P < .001). The quality of life score was also found to be increased to 11.17 after the surgery from 9.99 before the surgery by showing a significant difference (P < .001). CONCLUSION: In a future, the studies on the numbers of implanted loss teeth and the location of tooth loss are necessary, more long-term follow study are needed, and it is thought to be necessary to enlarge the sample size of subjects in conducting the studies.

With the aim of establishing bio-indices for the development of multistep hepatotumorigenesis, rats were fed water containing 0.01% diethylnitrosamine (DEN) ad libitum for 13 weeks. This treatment with DEN only made it possible to induce hepatic tumors in 100%. After the DEN administration, several clinical symptoms were observed including minor behavioral changes, brittleness of hair and a decrease in water and food intake. The concentration of total serum protein and albumin in all treated groups was significantly lower than in non-treated controls (p<0.05). Increase of specific enzyme (AST, ALT and GGT) activity (p<0.05), variable tumor size and hepatomegaly of the liver was observed in all rats treated with DEN for 10 weeks. Both hepatocellular carcinoma and cholangiocarcinoma were found in the same livers at the same time, and were prominently developed after 12 weeks. In case of carcinoma, some of the livers showed more or less advanced states over the 12-15 weeks period. In the present study, hepatocellular carcinoma was developed by treating DEN in only the drinking water, without any other carcinogens or without partial hepatectomy. These results indicate that DEN is a new carcinogen that acts directly on it the liver, moreover, it might be very useful for investigating hepatotumorigenesis.

PURPOSE: The purpose of this study was to identify factors affecting the social distance between minority groups and nursing cadets. METHODS: A cross-sectional survey design was used. A questionnaire was distributed to the entire Armed Forces Nursing Academy cadets. Data from 273 nursing cadets were analyzed using t-test, ANOVA, Pearson correlation coefficients and Stepwise multiple regression. RESULTS: Social distance had positive correlations with collective identity (r=.28) and multiculturalism (r=.37). A negative correlation was found between social distance and perceived threat (r=-.38). Perceived threat, multiculturalism, collective identity, and frequency of contact with minorities were identified as factors affecting the social distance. The model explained 24% of the variables. CONCLUSION: To effectively respond to the minority groups' nursing needs in the army, educational programs which help to reduce the perceived threat, to strengthen multiculturalism, and to establish a healthy collective identity of nursing cadets need to be developed.

The purpose of this study is to verify severity of asthma in asthmatic patients through through the arterial blood gas analysis. Subjects were consisted of 103 patients (74 boys and 29 girls), between 2~13 years of ages. Clinically, asthmatic patients were classified into 6 groups, i, e., group 0(no rhonchi), group 1(rhonchi only), group 2(mild attack), group 3(moderate attack), group 4(severe attack), group 5(respiratory failure with disturbance of consciousness). PH kept normal range in the group 0, group 1, group 1 and group 3,but began decrease in the group 4.There was linear fall in Po2 and began decrease in the group 3. HCO3- maintained normal level through the whole range. BE showed acidemia on the whole, and began distinctive decrease in the group 4 and group 5, especially. Hypoxemia, hypercapnia and acidemia were common in patients in severe attacks with disturbance of consciousness.

Activation of c-Jun N-terminal kinase (JNK) is associated with a wide range of disparate cellular responses to extracellular stimuli. In mammals, three JNK isoforms are known, and their differential regulation occurs in a stimulus- or a cell type-dependent manner. However, the underlying mechanism of this differential regulation has not been clearly elucidated. Here we demonstrated that JNK1 and JNK3 were activated in SH-SY5Y cells after treatment with H2O2 or UV. In SH-SY5Y cells overexpressing mJIP1, a splicing variant of a JNK scaffold protein JIP1, the H2O2-induced activities of both JNK1 and JNK3 were significantly suppressed. In the same cell line, however, UV-induced JNK1 activity was significantly suppressed, but JNK3 activity was not. During the RA-induced differentiation of SH-SY5Y cells, JNK1 was activated, whereas JNK3 was not, and this JNK1 activation was completely abolished in the cells overexpressing mJIP1. These results suggest that JIP1 plays a role in the regulation of the isoform-specific activation of JNKs in stimulus-dependent manner.

BACKGROUND: Carcinoembryonic antigen (CEA) is a glycoprotein on cellular surface, which is highly condensed in embryonic tissue and tumor of various kinds. Previous study found out that CEA may grow with various cancer or other diseases other than cancer as well. Besides, it is widely known that smoking also influences the rise in CEA. Among the same smokers, some of them show high CEA figures in serum when others remain in normal range. There are those whose pulmonary function is not influenced by smoking when that of others are susceptible to it. Therefore, this study was undertaken with an aim to study the relationship between serum CEA and pulmonary function by investigating how the change in pulmonary function caused by smoking influences serum CEA. METHODS: From Nov, 1997 to Feb, 2001, this study carried out tests on adult male smokers ages 35 to 64 who visited a hospital located in Kang Nung city. The subjects were divided into two groups: one group of 29 subjects with high CEA with over 6.0 ng/ml with normal colon study; the other group, which is the CEA normal group, consisted of 58 subjects selected through age adjusted random sampling. Data on personal information, smoking and clinical history was collected from a questionnaire. CEA was tested using radioimmunoassay of Abott. Pulmonary function was examined using Analyzer assembly Vmax 20C from Sensormedics Company. These examinations was limited to those who have been screened not to have cancer by chest X-ray, abdominal ultrasonography, and duodenofibroscopy. RESULTS: Smoking per day for the group with high serum CEA was 1.3 pack ( 0.4 pack), which was found to be significantly higher compared to that of normal group (P<0.01). Pack-years with high serum CEA group was 32.6 13.5 which was also comparatively higher than that of the normal group with 22.4 10.9 (P<0.01). Pulmonary function test indicated that FEV1 for the group with high serum CEA was 3.0 0.5 L, which marked lower than that of the normal group with 3.4 0.5 L (P<0.05). After compensating for age and pack years, FEV1 decreased in proportion to the rise in CEA. CONCLUSION: This study has established a link between serum CEA and daily smoking, pack years, and pulmonary function and found that FEV1 was inversely proportionate to the rise in CEA regardless of corrected pack years and daily smoking. Consequently, serum CEA alone is thought to be related to the pulmonary function. Therefore, it is advised that smokers with high serum CEA need to take heed of the influence on pulmonary function.

BACKGROUND/AIMS: Peritoneoscopy allows the clinician to assess the activity of the surface of the liver and helps him to make a prognosis in cases of liver disease by judging the structural changes of the surface. In chromoperitoneoscopy using an intravenous injection of indocyanine green (ICG), hepatic parenchyme is stained after intravenous injection of ICG while interstitial connective tissue, fatty deposition and hepatoma are not. So diagnostic accuracy is, therefore believed to be elevated in chromoperitoneoscopy than conventional peritoneoscopy or blind liver biopsy. This study was performed to assess the clinical usefulness of chromoperitoneoscopy in various chronic liver diseases. METHODS: Intravenous ICG was administered at 2 mg/Kg mixed with 20 cc of saline in 30 cases with several kinds of hepatic disorders during conventional peritoneoscopic examinatians. Liver surface was examined 5 minutes after ICG injection.

Gastrointestinal hemorrhage is a recognized complica tion of chronic pancreatitis and has been reported to occur in up to 20% of cases. Visceral vessel aneurysm such as gastroduodenal artery aneurysm associated with chronic pancreatitis is rare but clinically important vascular lesion because it carries a high mortality, making early diagnosis and treatment essential. The conventional treatment has been surgical liga tion or resection of aneurysm which is associated with high mortality and morbidity. So transarterial emboliza tion has been used recently in preference to surgery to stop the hemorrhage from this aneurysm. We report a case in which bleeding from a gastroduo denal artery aneurysm, caused by chronic pancreatitis, was successfully treated by embolization using a metallic micro coil.

OBJECTIVE: The aim of the present study was to investigate the visual perception difference between ADHD children with and without sensory processing disorder, and the relationship between sensory processing and visual perception of the children with ADHD. METHODS: Participants were 47 outpatients, aged 6-8 years, diagnosed with ADHD. After excluding those who met exclusion criteria, 38 subjects were clustered into two groups, ADHD children with and without sensory processing disorder (SPD), using SSP reported by their parents, then subjects completed K-DTVP-2. Spearman correlation analysis was run to determine the relationship between sensory processing and visual perception, and Mann-Whitney-U test was conducted to compare the K-DTVP-2 score of two groups respectively. RESULTS: The ADHD children with SPD performed inferiorly to ADHD children without SPD in the on 3 quotients of K-DTVP-2. The GVP of K-DTVP-2 score was related to Movement Sensitivity section (r=0.368*) and Low Energy/Weak section of SSP (r=0.369*). CONCLUSION: The result of the present study suggests that among children with ADHD, the visual perception is lower in those children with co-morbid SPD. Also, visual perception may be related to sensory processing, especially in the reactions of vestibular and proprioceptive senses. Regarding academic performance, it is necessary to consider how sensory processing issues affect visual perception in children with ADHD.

PURPOSE: We wanted to evaluate the effective methods that are appropriate for an endemic area of thyroid disease and to compare the differences of cytologic diagnostic rates with and without using a peculiar smear technique. MATERIALS AND METHODS: We analyzed the incidence rate of insufficient results, complications and the total procedure times of 1,126 thyroid nodules in 776 patients who underwent US-FNAB (ultrasonography-guided fine-needle aspiration biopsy) from January to December 2005. We compared the diagnostic rate between the two groups; the groups' tests were performed with a peculiar smear technique (Group A, n = 313) or with a conventional smear technique (Group B, n = 250). RESULTS: According to the size of the thyroid nodule, the incidence rate of an insufficient result on US-FNAB and the mean total procedure time for 1126 thyroid nodules in 776 patients were measured as 16.9% (52/308) and 208 seconds for nodules under 0.5 cm, 9.8% (30/306) and 160 seconds for nodules between 0.5 cm-1.0 cm, and 6.0% (30/504) and 134 seconds for nodules over 1.0 cm. These 776 patients showed no significant complications, except for mild pain. In Group A, the incidence rate of an insufficient result was calculated as 15.1% (14/93) for the group with nodules under 0.5 cm, 5.3% (5/95) for the group with nodules between 0.5 cm-1.0 cm, 4.8% (6/125) for the group with nodules over 1.0 cm, and 8.0% (25/313) for the total A Group. In Group B, the incidence rate of an insufficient result was measured as 33.3% (15/45) for the group with nodules under 0.5 cm, 28.1% (25/89) for the group with nodules between 0.5 cm-1.0 cm, 21.4% (24/112) for the group with nodules over 1.0 cm, and 25.7% (63/245) for the total B group. There was a statistically significant correlation between the rate of an insufficient result and the peculiar smear technique or the size of the thyroid nodule. CONCLUSION: We consider that US-FNAB is very simple, safe and accurate diagnostic method for thyroid nodules, and US-FNAB with a peculiar smear technique is able to increase the diagnostic rate for thyroid nodules.
