PURPOSE: The purpose of this study was to examine the health behaviors (such as smoking, alcohol consumption, exercise, duration of sleep, body weight, eating habit of breakfast and snack) affecting self-perceived health status, and to determine the relationships. RESEARCH METHODS: This study utilized the data from Korean National Health Survey (KNHS) in 1992. The data consisted of random sample of 2,799 individuals (1,304 male and 1,495 females) whose ages were between 20 and 59. The analytic methods for the study were chi square analysis, logistic regression. RESULTS: The results of the study were as follows : (1) There was a negative relationship between duration of smoking and health status in linear pattern; (2) The frequency of alcohol drinking had a significant relationship with health status in quadratic pattern. That is, the health status of moderate drinkers was better than that of non-drinkers and heavy drinkers; (3) There was no significant relationship between the frequency of exercise and the health status. But in further analysis, the relationship between them was positive in linear pattern. That is, the health status of daily exercisers was better than that of the others; (4) Duration of sleep significantly influenced the health status in quadratic pattern. That is, the persons who sleep for 7-8 hours per day were better than that of the others; (5) The health status of persons with normal body weight was higher than that of persons with underweight or overweight; (6) Eating breakfast or not did not influence the health status, and taking snack or not influenced the health status; (7) In mutivariate analysis, The younger the persons were and the longer the level of education was, the higher the health status was in both male and female. In female, the higher the economic status was, the higher the health status was. And the smoking and the weight status significantly and independently influenced the health status in both male and female. And in male, the moderate drinking positively influenced the health status. CONCLUSION: History of no smoking, moderate alcohol consumption, regular exercise, 7-8 hours sleeping and maintaining the normal body weight were health-promotive behaviors. And especially no smoking, moderate drinking and maintaing the normal body weight singnificantly influenced the self perceived health status.

This study was aimed to investigate the clinical manifestation of nail changes in psoriasis and was based on analysie of 205 p oriatics visited the department of dermatology, Seoul National University Hospital from November, 1984 to June, 1985. The results were summerized as follows: Nail changes were noted in 78(38. 0%) out of 205 patients in the finger nails. Toe nails were involved in 26(12 7%) cut of 205 patients. 2 Nail changes in male were noted in 49 (46, 7%) out of 105 patients and in female, 29(29%) out of 100 patients. 3. The peak incidence of nail changes according, to age group was over 40 years (45. 1%.) and the lowest incidence, under 9 years(26. 7%). 4, Pitting(57. 7%) was the commonest change ii the finger nails and subungal keratosis(50. 0%) and discoloration(46 2%) in the toe nails. 5 Incidence of nail changes according to psoriatic type was 23. 7% in guttate type, 42. 6% in nummular type, 53 3% in annular type. 6 The patients with the more severe degrees of psoriasis had a higher incidence of nail involvement. Mean duration of psoriatics with nail change and without nail change was 6. 3 years and 6. 5 years, respectively, 8 Among 65 patients with psoriatic nails, onychomycosis was noted in 9 patients(13.8%).

This study was performed to investigate the stimulating effect on oocyte maturation and cumulus cell expansion in TC199 media by human cord serum (HCS) supplementation. Immature mouse oocyte cumulus complexes (OCCs) were cultured in TC199 media supplemented with bovine serum albumin (BSA), HCS and human chorionic gonadotropin (hCG) instead of luteinizing hormone (LH) respectively, and the expression of cumulus expansion and oocyte maturation were observed. After 4hr and 24hr culture with or without OCCs, media containing 0.4% BSA, 10% HCS and 10 lU hCG respectively were collected and analyzed for changing concentrations of estradiol (E2), progesterone(P4), testosterone(T), and PGF2. There were no elevation of E2, T, and PGF2 by OCCs culture, but minute elevation of P4 level by 24hr OCCs culture in hCG supplementation (p=0.048). The stimulating pattern of cumulus expansion of OCCs by HCS and hCG supplementation was similar to our previously report using Ham's F-10 media, however oocyte maturation rates after 24hr OCCs culture in all media were increased by 20~30% compared to Ham's F-10 media. These results suggest that LH in HCS induce cumulus expansion probably by P4 secretion of OCCs, and TC199 is efficient media for immature mouse oocyte maturation.

Both irritation and staining reaction of anthralin on the skin are the two most important problem of therapy. Irritation, such as erythema, edema and staining by p. lg anthralin ointment were studied with the chamber-testing technique in 21 psoriatic patients. We campared the skin reaction of short exposure time, such as 1 hour, 2 hours, and 3 hours with those of exposure of 24 hours through 3 days after application. The results were as follows: l. Incidence of erytherna reaction was 81.9% in exposure of 1 hour, 85.7%, in 2 hours, 90.5%, in 3 hours and 100% in exposure of 24 hours. Degree of erythema reaction was increased according to duration of application. 2. There were no edematous reactions in exposure of 1 hour or 2 hours, 9,5% in 3 hours and 28,6% of grade 1 reaction in 24 hours. 3. There was no staining reaction in exposure of 1 hour, 48% in 2 hours, 9.5%, in 3 hours and 71.4% in 24 hours. Degree of staining reaction elicited by short exposure time were all weaker than reaction caused by 24 hours exposure.

STATEMENT OF PROBLEM: How the ISQ values measured by Osstell(TM) and Osstell(TM) Mentor are related, and whether the ISQ values acquired from the two machines changes in accordance with changes in implant stability are not yet fully understood. PURPOSE: The aim of this study was to find out correlation between the ISQ values acquired from Osstell(TM) and Osstell(TM) Mentor, and to evaluate the clinical effectiveness and accuracy of two devices. MATERIAL AND METHODS: Sixty two implants were inserted into 47 patients, and their ISQ values were measured using Osstell(TM) and Osstell(TM) Mentor. In the first stage surgery, the ISQ values of forty four implants inserted into thirty five patients were measured. In the second stage surgery, the values of fifty implants inserted into thirty seven patients were measured. The values were analyzed to determine the difference between the mean ISQ values of Osstell(TM) and Osstell(TM) Mentor. In addition, the correlation between implants used in the first and second stage of surgery with regard to their types and areas of insertion were analyzed. The difference between the ISQ values of 32 implants in each patient during the first and second stage was analyzed. The statistical assessment was carried out using SPSS V. 12.0 for Win. (SPSS Inc., Chicago, USA). The Pearson correlation coefficient was used to examine the correlation between Osstell(TM) and Osstell(TM) Mentor in the first and second stages of surgery, whereas the difference between their ISQ values was evaluated using a paired t-test. RESULTS: In the first stage, the mean ISQ value for Osstell(TM) and Osstell(TM) Mentor was 70.84 and 75.09, respectively, showing a significant difference (P < .01). In the second stage, the mean ISQ value of Osstell(TM) and Osstell(TM) Mentor was 71.76 and 75.94, respectively, also showing a significant difference (P < .01). The difference between the ISQ values in patients in the first and the second stages was significant with both instruments. CONCLUSION: The significant difference in the values obtained using the Osstell(TM) and Osstell(TM) Mentor between the first and second stages of implant surgery indicates that these values can be a convenient and precise way for evaluating the implant stability in clinical practice.

The present study was undertaken to evaluate the efficacy of white petrolatum-UVB therapy on patients with psoriasis. Nineteen patients with chronic plaque type psoriasis selected in the Department of Dermatology, Seoul National University Hospital were treated with white petrolatum followed by exposure to UVB. Clinical response to therapy was graded as follows: Grade 1: Minimal improvement, Grade 2: Definite improvement Grade 3 Considerable improvement, Grade 4: Clearing. We campared the clinical response according to involved site: trunk and extremity. A responsive case was defined as a case with G4 in trunk and/or extremities. The results can be summarized as follows: 1. Fourteen of the 19 patients(73. 7%) were classified as being responsive cases. 2. Among the responsive cases, the 11 cases of trunk lesion all showed G4 clea- ring. The extremities lesion cases showed G4 clearing in 9 out of 14 cases, the other 5 cases showing GR. This showed that the trunk lesions were more responsive to the treatment than the extremities lesions. 3. In the cases of trunk lesions, the mean number of therapy was 6. 3 for G2 response, 11. 2 for GR and 16. 7 for GR. In the cases of extremities lesions, the mean number of the therapy was 8. 6 for G2, 16. 1 for GR and 19. 2 for Gl. 4. Pruritus was a complaint in 13 patients (68. 4%) during therapy. Among them moderate to severe pruritus was noticed in 6 cases (51. 6%). From the above results the emollient phototherapy seems to be an effective therapy in the treatment of psoriasis.
