In spite of continuing efforts by many researchers and clinicians to improve oral functio, the number of patients with missing teeth resulting from periodnotitis and dental caries has not substantially decreased in Korea. Patients who use removable denture have relatively insufficient masticatory function. Various dental implants have been developed by a number of researchers to improve masticatory function. This study was undertaken to investigate the maximum bite force and masticatory function after implantatioin. A total 23 patients were treated with implantation at the Dept. of oral and maxillofacial surgery, college of Dentistry, PUSAN national university. The patient had natural tooth, the contralateral sides had implant-supported prostheses. The results were follows 1. The maximum bite force was little greater in implant-supported prostheses as 39.7kg than natural tooth as 36.8kg. This is because of the lack of periodontal ligament or inhibitory-reflex mechanism, higher maximal bite force could be expected when teeth are replaced by implants. 2. The maximal bite force is greater on implant-supported prostheses than natural tooth, but the masticatory function is higher at natural tooth. All of the patients who had implant-supported prostheses were comfortable during chewing the food. But, the masticatory function decrease because of psychologic problem and character of Korean food.

The 1224 cataractous patients who had extracapsular cataract extraction and posterior chamber lens implantations were evaluated retrospectively irrespective of style, postoperative position of intraocular lens and surgeon. The 100 cataractous patients who had extracapsular cataract extraction and posterior chamber lens implantations in the bag accurately using single lens style by one surgeon(E.H.L) were evaluated prospectively. And then the predictive accuracy of the SRK/T intraocular lens power calculation formula was compared with other formulas (SRK, SRKII and Holladay) without consideration of individual A constant. The SRK/T formula was more accurate than other 3 formulas in all axial length, but there were no significant differences statistically. Especially for short and long eyes, SRK/T formula was more accurate than other 3 formulas.

The purpose of this study was to identify the degree of sexual adjustment and quality of life in married men with spinal cord injuries and to furnish primary data to sexuality rehabilitation nursing practice which can lead to ideal sexual life and quality of life those men with SCl. Seventy married men with SCI were conveniently sampled in Kwangju, Suncheon, Mokpo and Seoul for responding the questionnaire, which was based on this research. With the research scale, SIS(Sexual interest and satisfaction) by Siosteen et al.. (1990) and SB(Sexual behaviour) by Kreuter et al.(1996) were used for the measurement of sexual adjustment. And, for measuring quality of life was used SCI QL-23(Spinal cord injury of life-23) scale by Lundqvist et al. (1997). Data were collected from January 20 to March 20, 1999, using a structured questionnaire. A hundred volumes of questionnaire were used, and 85 volumes were collected, 70 volumes were used as research data after excluding 15 volumes unsuitable to data analysis. The obtain data were analysed using percentage, t-test. ANOVA. Duncan test, and Pearson's correlation by SAS PC+ program. The results were as follows: 1. The mean score of sexual interest and satisfaction of the subjects was 8.42, out of 18. The ways of their sexual behavior after spinal cord injuries were embracing and caressing (62.9%), kissing(58.6%), caressing breast with hands (55.7%), caressing breast with hands (52.9%), caressing genitals with hands (37.2%), caressing genitals with mouth(30.0%) and sexual intercourse (18.6%). The mean score of quality of life was 52.53 out of 100. 2. Age(F=3.24. p= .045) and caregiver (F=4.02. p=.022)were major variables which reveals significant differences in terms for sexual interest and satisfaction. The later results on Duncan's test showed that subjects who were in their 30s or 40s were significant higher than subjects whose age were in their 50s in their sexual interest and satisfaction. Also subjects with their spouse's care or mother's care were higher than those with other's care. 3. Subjects with incomplete paraplegia were higher than those with the complete paraplegia in sexual interest and satisfaction(F=3.01. p= .036). 4. Variables that showed the significant differences in the quality of life were education(t=2.860. p= .007) and period of marriage(t=2.125. p=.037). and occupational status(t=-2.161. p=.034). High school graduates. those who married before spinal cord injuries and those who didn't have occupation were higher than the other subjects. 5. Variables that revealed significant differences in the quality of life were time passage after spinal cord injuries(F=8.72. p=.001) and injured level of spinal cord(F=3.32. p= .042). Duncan's test showed that subjects who had lived for less than 4 years were higher those with time passage of 5-9 years and 10 years. Also subjects with lumbar injuries were higher than those with thoracic injuries in terms of quality of life. 6. There was negatively correlated between sexual interest and satisfaction and quality of life(r=- .256. p .05). As a result of these findings sexuality rehabilitation for individuals with SCI was very important issue for their quality of life. Thus, registered nurses who care clients with SCI should activily participate in the client's sexual needs. Also, various sexual behaviors as well as sexual intercourse should be encouraged for the sexual adjustment of client's with SCI.

Asphyxia is the most important perinatal cause of neurologic morbidity in infants. Recently, elevated levels of CK-BB have been demonstrated in serum after asphyxic insult in infants. To evaluate the possibility of using serial measurements of CK-BB activity as a diagnostic method and a predictor of neurologic outcome in asphyxiatic infants. We studied CK-BB activity in serum of asphyxiated infants (16 preterm babies, 41 term babies) and healthy infants (11 preterm babies, 12 term babies) from birth (cord) to 5 days of serially. The results were as follows 1) Serum CK-BB activites (cord 76.0IU/L, 12 hours 34.1 IU/L, 1 day 22.4 IU/L, 2 days 8.2 IU/L) of asphyxiated preterm infants were much higher than those (cord 4.4IU/L, 12 hours 2.4IU/L, 1 day 1.6 IU/L, 2 days 1.1 IU/L) of healthy preterm infants, but there were no significant differences (P values>0.05). 2) Serum CK-BB activities (cord 59.0 IU/L, 12 hours 23.6 IU/L, day 17.6 IU/L) of asphyxiated term infants were significantly higher than those (cord 2.4 IU/L, 12 hours 2.7 IU/L, 1 day 0.4 IU/L) of healthy term infants (P values<0.05) 3) There were no significant differences in serum CK-BB activities between asphyxiated preterm infants who showed late neurologic deficits (P values>0.05) 4) Serum CK-BB activity (131.7 IU/L) at birth (cord) of asphyxiated term infants who showed late neurologic deficits was significantly higher than that (49.8 IU/L) of asphyxiated term infants who did not show late neurologic deficits (P value<0.05) In conclusion, it is suggested that serial measurement of CK-BB activity in serum of asphyxiated term infants from birth (cord) to 1 day of age is an available test for diagnosis of neonatal asphyxia and for a prediction of neurologic outcome of neonatal asphyxia.

BACKGROUND: The reproducibility in grading a cervical intraepithelial neoplasia (CIN) are not perfect. The aim of this study was to assess the value of the immunohistochemical expression of p63 and the other biomarkers for grading a CIN (dysplasia and in situ carcinoma), and diagnosing invasive carcinomas. METHODS: Sixty six cervical specimens were immunostained with the monoclonal antibodies against p63, Ki-67, p27Kip1, and p53 to determine the localization. RESULTS: The p63 positive cells are well linked with squamous cell maturation and the degree of dysplasia. In mild dysplasia, the p63 positive cells were localized to the basal and parabasal cells, which gradually extended into the middle and upper layers in moderate and severe dysplasia. p63 expression was strong in immature squamous epithelium and invasive squamous cells, but was constantly absent in an adenocarcinoma. The Ki-67 positive cells were scattered from the parabasal cells to the superficial cells in accordance with the degree of dysplasia. p27Kip1 expression was noted in the intermediate cells in the normal cervix. In CIN, the p27Kip1 positive nuclei tended to extend to the basal cells, but it showed no diagnostic consistency in an invasive carcinoma. p53 expression was also variable. CONCLUSION: p63 is a useful diagnostic adjunct for grading CIN as well as for detecting microinvasion and squamous differentiation in invasive carcinoma. However, immunohistochemical expressions for the p27Kip1 and p53 have no correlation with the grade of CIN and squamous cell carcinoma.

PURPOSE: To describe the magnetic resonance (MR) findings of intracranial dural arteriovenous fistulae (DAVF) and associated venous hypertensive diseases, and to determine their diagnostic value. MATERIALS AND METHODS: MR Imagings of twelve cases of angiographically-proven intracranial DAVF were analyzed. The presence of signal voids, dilatation of involved dural sinus, the dilatation of the extra/intradural venous system, high signal intensity on T2 weighted image, cerebral edema, intracranial hemorrhage, and hydrocephalus were retrospectively analyzed. MR findings and angiographic classification were compared. RESULTS: In 11 of 12 patients (92%), MR revealed the location of DAVF. In five cases, these were cavernous, and in six, they were extracavernous; the locations of the latter were as follows: superior sagittal sinus (SSS), 4: torcula, 1; lateral sinus & SSS, 1. Except for the lateral sinus lesion, all the DAVF seen in thses 11 patients showed the presence of signal voids and dilatation of the involved dural sinus. Findings of associated venous hypertensive disease, namely dilatation of the superior ophthalmic vein and cortical venous system, cerebral edema, and high signal intensity on T2-weighted images were observed in three cavernous lesions (50%), but all extracavernous DAVF (100%) showed associated venous hypertensive disease. When the grade of angiographic classification was high and reflux of sinus blood to the cortical vein was seen on angiography, the MR findings of intracranial venous hypertension showed good correlation. CONCLUSION: The MR findings of DAVF include dilatation of the dural sinus and signal voids of feeding arteries and draining vein. Other findings which suggest intracranial venohypertensive disease are dilatation of the cortical and medullary vein, hydrocephallus, cerebral edema and intracranial hamorrhage. These and the angiographic findings correlate well and suggest that in the diagnosis of DAVF and the detection of intracanial venohypertension, MR is a non-invasivse technique which can be use be usefully employed before final diagnosis by angiography.

One case of unilaterally developed acute retinal necrosis syndrome was studied with retina and vitreous from biopsy during operation through electronmicroscope pathologically and virolo gically. In photoreceptor cells, generalized necrosis was found: loss of outer segments, fragmentation of inner segments, and decrease of mitochondria in ellipsoids. Bipolar cells and axons were well preserved. Internal limiting membrane was intact, and covered by an unidentified cell. Degenerated retinal proper had various sized vacuoles. Around the intraretinal vessels, neutrophils and lymphocytes were infiltrated considering vasculitis. In ganglion cells, swelling of mitochondrias were seen, and their cell organelles were decreased, No virus particle was detected in all layers of the retina with electronmicroscope.

This study tested how S/N (Signal to Noise Ratio) ratios and ADC (apparent diffusion coefficient) values vary with different T-scores in a group of patients with osteoporosis. Based on DEXA (Dual Energy X-ray Absorptiometry) T-scores for L1?L4 for two groups of subjects consisting of 30 healthy people without osteoporosis and 30 patients who came for treatment of waist (lumbar or low back) pain and were suspected to have osteoporosis as judged from the simple X-ray findings, this study classified every spine into two groups of osteoporosis and osteopenia. Signal intensity measurements were made in the four regions of L1 to L4 on diffusion-weighted MR images obtained using 1.5T MR scanner, while ADC measurements were obtained from ADC map images. As an approach for quantitative analysis, the comparison of the variances in S/N ratios and ADC values for varying T-scores in the selected regions of interest was carried out based on averaged T-scores, S/N ratios, and ADC values. Also, the variances in S/N ratios and ADC values for each of the groups of osteoporosis and osteopenia, which were classified into by T-scores, were compared. For qualitative analysis, a careful naked eye examination of signal intensity differences in the area of L4 was made on T1-weighted sagittal images for each of the healthy (normal), osteopenia, and osteoporosis groups. In the qualitative analysis, it was found that for both the osteopenia group and the osteoporosis group, as T-scores deceased, the S/N ratios on diffusion-weighted MR images also decreased, with the greatest decrease in the S/N ratio found in the osteoporosis group. Additionally, among the three groups, the lowest S/N ratio was found in the osteoporosis group. With respect to ADC map, it was found that for both the osteopenia group and the osteoporosis group, as T-scores deceased, the ADC values on diffusion-weighted MR images also decreased, with the greatest decrease in the ADC values found in the osteoporosis group. Additionally, among the three groups, the lowest ADC value was found in the osteoporosis group. On the other hand, in the qualitative analysis, the osteoporosis group showed the highest signal intensity. Additionally, among the three groups, the lowest signal intensity was found in the healthy (normal) group. It was found that as osteoporosis progressed, S/N ratio and ADC decreased, whereas signal intensity increased on T1-weighted images. Also, in diagnosing osteoporosis, MRI tests turned out to be (more) effective.
