The role of the periosteum on osteointegration of Bio-Oss(R)(Geistlich, Wolhusen/Switzerland) was studied in rabbit calvarial defect. 12 New Zealand white male rabbits between 2.8 and 4 kg were included in this randomized, blinded, prospective study. Each rabbit was anesthetized with Ketamine HCl(5 mg/kg) and Xylazine HCl(1.5 ml/kg). An incision was made to the bony cranium and the periosteum was reflected. Using a 6-mm trephine bur(3i. USA), four 8-mm defects were created with copious irrigation. The defects were classified into barrier membrane(Tefgen(R), Lifecore Biomedical, Inc, U.S.A.) only group as a control, Bio-Oss(R) with barrier membrane group, Bio-Oss(R) with periosteum covering group, and Bio-Oss(R) without periosteum covering group. There were 2 rabbits in each group. The wound was closed with resorbable suture materials. Rabbits were sacrificed using phentobarbital(100 mg/kg) intravenously at 1, 2, and 4 weeks after surgery. The samples were fixed in 4% paraformaldehyde, and decalcified in hydrochloric acid decalcifying solution(Fisher Scientific, Tustin, CA) at 4degrees C for 2-4 weeks. It was embedded in paraffin and cut into 6 micrometer thickness. The sections were stained with H & E and observed by optical microscope. The results were as follows; 1. The periosteum played an important role in osteointegration of Bio-Oss(R) in bone defects. 2. When the periosteum remained intact and Bio-Oss(R) was placed on the defect, Bio-Oss(R) with periosteum covering has been incorporated into the newly formed bone from 2-week postoperatively. 3. When the periosteum was removed at the surgical procedure, invasion of connective tissue took place among the granules, and new bone formation was delayed compared to periosteum covering group. Therefore, when the bone grafting was performed with periosteal incision procedure to achieve tension-free suture, the integrity of the overlying periosteum should be maintained to avoid fibrous tissue ingrowth.

INTRODUCTION: The purpose of this study was to investigate the changes in the concern and attitudes of Nursing students toward the disabled before and after the disability experience program. METHOD: 151 Nursing students with clinical practice in National rehabilitation hospital were conveniently selected as the subject. All subjects had experience the disability program, and their attitudes toward the disabled were measured before and after the 3hours' program. Collected data were analyzed by SPSS 11.0 with paired t-test. RESULTS: 1. The concern toward the disabled after their disability experience program was more positive than before(t= -4.930, p= .000). 2. The attitudes toward the disabled after their disability experience program was more positive than before(t=5.892, p=.000). 3. The appreciation of daily life after their disability experience program was higher than before(t=- -8.563, p= .000). CONCLUSION: In summary, the disability experience program should be effective in order to promote the positive attitude toward the disabled. Therefore expansion of this program is of profound significant.

The primary objective of this study was to make the prediction percentile tabulation of the sum of mesiodistal widths of the unerupted permanent canines and premolars derived from the sum of mesiodistal widths of the erupted permanent incisors in normal and crowding groups. Crowding group consisted of 85 pairs of dental casts (42 males and 43 females) with more than 4mm of crowding in anteriors. Normal group consisted of 109 pairs of dental casts (65 males and 44 females) with less than 1mm of spacing or crowding in anteriors. The mesiodistal crown diameters of permanent teeth were measured from the dental casts using the sliding calipers (Mitutoyo Co., Japan). From the study, the obtained results were as follows: There were not significant differences between male and female in both groups on the basis of the ratios between the sum of mesiodistal widths of incisors and the sum of mesiodistal widths of canines and premolars. There was not significant difference between two groups on the basis of the ratio between the sum of mesiodistal widths of mandibular incisors and the sum of mesiodistal widths of mandibular canines and premolars and was significant differences between two groups on the basis of the ratio between the sum of mesiodistal widths of mandibular incisors and the sum of mesiodistal widths of maxillary canines and premolars. There was significant difference between two groups on the basis of the ratio between the sum of mesiodistal widths of maxillary incisors and the sum of mesiodistal widths of mandibular canines and premolars. There was significant difference between two groups on the basis of the ratio between the sum of mesiodistal widths of maxillary incisors and the sum of mesiodistal widths of maxillary canines and premolars. The percentile prediction tabulations were made in an attempt to predict the sum of mesiodistal widths of the unerupted permanent canines and premolars derived from the sum of mesiodistal widths of the erupted permanent mandibular incisors in each group. The percentile prediction tabulations were made in an attempt to predict the sum of mesiodistal widths of the unerupted permanent canines and premolars derived from the sum of mesiodistal widths of the erupted permanent maxillary incisors in each group.

This study was performed to investigate the nutrition knowledge, attitudes, and dietary habits of physical education (PE) major and non-majors of male college students. The subjects were 253 students residing in Gyeonggi area. Nutrition knowledge scores of PE major students were lower than that of non-major students. Both PE major and nonmajor students reported TV, radio, and internet as their primary sources of nutrition information. Overall dietary attitude scores of two groups did not differ significantly, but PE major students showed more positive attitudes than non-major students for 'Enjoy eating foods that are good for health'. PE major students took more number of meals a day and took more irregularly than non-major students. Also they used more nutrient supplements than non-major students. PE major students drank more amounts of alcohol and drank more frequently than non-major students. But the smoking status of the two groups was not significantly different. PE major students scored higher than non-major students in dietary habits on balance of meals in spite of their low nutrition knowledge scores. Therefore, it is suggested that nutritional programs for PE major and non-major college students should be developed.

The study was performed to investigate the relationship of regular exercise to body composition and nutrient intakes of male college students by comparing anthropometric measurements and one-day dietary intakes by 24-hour recall of physical education (PE) majors and non-major male college students. The subjects were 253 students residing in the Gyeonggi area. Only 64.1% and 32.1% of PE majors and non-major students exercised over 4 times a week and PE major students did stronger exercise than the non-major students did. Mean BMI and WHR (Waist Hip Ratio) of the two groups were not different. But percentages of body fat and lean body mass in PE major students were lower and higher, respectively, than those of non-major students. PE major students consumed significantly more energy and other nutrients except iron, niacin, vitamin C, and vitamin E than non-major students. Nutrients consumed less than KRDA was calcium in PE major students and energy, calcium, zinc, vitamin B12, folate, and vitamin C in non-major students. Mean adequacy ratio (MAR) of PE major students (1.00) was significantly higher than that of non-major students (0.94). Index of Nutritional Quality (INQ) of all nutrients except vitamin A of PE major students was also significantly higher than that of non-major students. Nutrients below 1.00 in INQ of both groups were calcium, zinc, vitamin B2, and folate. Our data supports that regular exercise may positively influence on body composition and increase diet quality in male college students. Therefore, an educational program focused on regular exercise along with proper dietary behavior would be needed.

Three cases of hydatidiform mole with a coexisting fetus are described. In two cases, flow cytometric analysis of nuclear DNA content from paraffin-embedded, molar tissues and normal-appearing placental tissues showed diploid pattern. One case had karyotypes of 46, XX both in fetal skin fibroblasts and in molar tissues. Microscopically, the villi showed diffuse hydropic swelling with circumferential trophoblastic proliferations and consistent with the diagnosis of complete mole. Two patient had persistent gestational trophoblastic neoplasia on the follow-up. Therefore, in cases of hydatidiform mole with a coexisting fetus, dizygotic twin pregnancies composed of a normal pregnancy from one ovum and a complete mole pregnancy from the other ovum must be considered and the patients should be followed with serum beta-hCG measurements.

A retrospective clinical study on 63 cases of intussusception in infants and children, who were admitted to the department of pediatrics and surgery from May, 1974 to Feb. 1978, was done. The prognosis of this disease is dependent upon early diagnosis and treatment but the causatio of this disease is not clear yet. It is a relatively common disease and we think it is worthwhile to analyze our won cases. The results were : 1. Among 63 cases, 37 were admitted to the department of pediatrics and 36 were admitted to the department of GS. 2. In age distribution, 85% of the patients were under 1 year of age and the peak incidence was 3~9 months of age. 3. Male was predominant than female. Male to female ratio was 2.8:1 4. The 58.8% of the patients were above 50 percentile of body weight comparing with Korean standard data. 5. In the aspect of the etiology, 96.9% of the cases were idiopathic and only 3.1% of the cases had organic causes. 6. The 4 cardinal symptoms were abdominal pain(93.7%), vomiting(90.%), bloodymucous stool(80.1%) and abdominal mass(74.6%) 7. Among the cases, colocolic type was 33.3%, ileocolic type was 22.2% and ileocecal type was 20.6% 8. The 71.4% of the cases were reduced successfully by barium enema. 9. Recurrence rate was 4.8%.

We experienced a case of athyrotic cretinism in a 9 month old female patient. She had a history of prolonged jaundice in neonatal period. The physical findings that suggest she had hypothyroidism were large anterior fortanel, unbilical hernia, widely separated suture line of the skull, large and protruded tongue, eyelid edema, no eruption of any tooth and skin change. X-ray film of the both wrists showed no calcification center of the right capitate. Thyroid function test revealed 5.3%, 6.3%, 3.9% and 1.8% at 2 hours, 4 hours, 24 hours and 48 hours after I131 uptake respectively. T3 value was 13.4%. T4 was 0.75ug/dl. No evidence of thyroid activity was noted on the thyroid scan.
