To demonstrate possible influences of general bone density on the mandible, histomorphometric analysis was carried out in mandibles and iliac bones and the correlation of the two bone densities was tested. Comparison of bony density in women and men over 60 years in the mandible was carried out too. Quantitative computed tomography (GCT) was taken in cross-section of mandibles at the same site where histomorphometric analysis was performed to evaluate the reliability of QCT. The analysis included 40 cadavers with no known disease affecting the bones. The subjects consisted of 15 females and 25 males with a mean age of 60.3 years. Spearman correlation analysis and Wilcoxon rank sum test was performed. The results were as follows. 1. There was statistically no correlation between the mandible and iliac bone in the walues of corrected cortical width (CCW), cortical porosity (POR) in cortex, and total bone volume(TBV), mean trabecular plate thickness (MTPT), mean trabecular plate density (MTPD), and mean trabecular plate separation (MTPS) in trabecular bone. 2. Comparison of women and men over 60 years, men had statistically higher bone density than women except for POR of buccal and lingual cortex, and MTPD of alveolar trabeculae in mandible. 3. There was statistically significant correlation between TBV of trabecular bone and CT NO., but not between POR and CT No. In mandible. According to the results above, there was no correlation between mandible and iliac bone density and between mandibular bony density and age. Further studies are required to support the results. A more noninvasive method to be able to measure the bone density of mandible should be developed and it is necessary to accumulate data on the normal values of bone density of mandible according to age and sex. Further study should be carried out about QCT to measure mandibular bony density using QCT.

This dental anthropological study was performed to analyse male and female students of Che-ju high school students. Cephalometric X-rays and dental casts were obtained of 60 male and 60 female students and the Mean and Standard Deviation were obtained. There was no difference in craniofacial morphology between male and female students but the size of craniofacial skeleton of the male is bigger than that of the female. The distance from NB line to pogonion is longer in the male group, and it meant that mandibular symphysis of the male is well developed than the female. The size of teeth of the male is larger than that of the female and is significant in upper and lower canine and first molar. The size of upper arch width, intercanine width, basal arch width and lower basal arch width of the male is larger than that of the female, but arch length of the male and the female showed no significant difference.

Our study was performed to evaluate the efficacy of anthralin-UVB therapy on patients with psoriasis. We studied twenty two patients suffering from plaque-type psoriasis of varying degrees of severity. The results can be summarized as follows. l. 2p patients(90.9%) out of the total 22 patients showed grade 4 improvement. The rernaining 2 patients failed to respond to treatment, 2. Arnong the improved 2Q patients, 2 patients who were treated more than 3p times for grade 4 improvement were excluded, so cleared patients were 18(81.8%). 3. Arnong the 18 cleared patients, the mean nurnber of therapy wasg. 6 for grade 3 and 12. 5 for grade 4 in the cases of trunk lesiona, and 13. 2 for grade 3 and 17. 8 for grade 4 in the cases of extrernities lesions. With above results, anth-ralin-UVB therapy was rnore effective in lesions of the trunk than in those of extremi.ties. 4. Notable side effects were pruritus in 6 patients(27.3pg), staining in 4 patients (18,2%), and 1ITltatioB in 2 patients(9.1%)

The study was undertaken to clarify any quantitative abnormalities in peripheral blood T lymphocytes and T subsets, mediating cell meliated immunity, and the presence of any relation between the degree of quantitative abnormalities and extent of skin lesions and activity of disease in patients with psoriasis by monoclonal antibodies. The results were as follows. 1. Mean percentages of total and suppressor T lymphocytes in 39 patients with psoriasis are significantly decreased as compared with those in 32 controls. Mean ratio of percentage of helper T lymphocytes to that of suppressor Tlymphocytes in 39 patients with psoriasis are significantly increased as compared with that in 32 controls. 2, As classified into three groups according to extent of skin lesions (E: less than 5% E,: 5-30%, and E,: more than 30%), mean pereentages of total T lymphocytes in E, and E, psoriasis group and those of suppressor T lymphocytes in all three psoriasi., groups are significantly decreased as compared with those in controIs. Mean percentages of helper T lymphor,ytes in L psoriasis group and mean ratios of percentage of helper T lymphocytes to that of suppressor T lymphocytes in E, and E, psoriasis groups are significantly increased as compared with those in controls. 3. Cis classified into three groups according to activity of disease (A,: stationary, A,: active, peripherally spreading and A,: active, small papules spreading), mean percentage of total T lymphocytes in peripheral blood lymphocytes in A, psoriasis group and those of suppressor T lymphocytes in all three psoriasis group are significantly decreased as compared with those in controls. Mean percentages of helper T lymphocytes and mean ratios of percentage if helper T lymphocytes to that of suppressor T lymphocytes in A, and A, psorixsis groups are significantly increased as compared with those in controls. These results clarified that there are quantitative abnormalities in peripheral blood I' lymphocytes and T subsets in patients with psoriasis and the degrees of abnorrnalities are related to extent of skin lesions and activity of disease. The aanorrnalities in peri.pheral blood T lymphocytes and T subsets in patients with psoriasis seem to be attributed to primary defect of suppressor T lymphoytes.

We performed anthralin comparative study(0.01% vs 0.1%) to assess the effectiveness of low-strengh anthralin therapy in 34 psoriatic patients and the resu1ts can be summarized as follows. 1. In the case of 13 patients using Burdick UVB larnp, in 1 patient the effect of 0.1% anthralin was superior to that of 0.01% anthralin from the start to the end of treatment, in 5 patients(38.5%) initially the effect of 0.1% anthralin was superior but in time became equal to that of 0.01% anthralin, and in 7 patients (53.8%) the effect of either side was same throughout the courae of the treatment. In the case of 21 patients using Waldmann UVB cabinet, there were 2(9.5 %), 3(14.3%) and 16 patients(76.2%) in the order named above. 2. The side effect of 0.1% anthralin was more severe than or at least the same as that of 0.01% anthralin in every patient who complained about side effects. So low-strengh anthalin-UVB phototherapy was thought to be the effective and alternative method of treatment particularly for the purpose of lessening the side effects.

Our study was performed to evaluate the efficacy of anthralin-UVB therapy for psoriasis by simplifying the conventional Ingram regimen, 34 patients(21 admitted, and 13 OPD patients) were included in our study and the resulti can be summarized as follows. 1. There were no cases of treatment failure. 16 patients(76. 2%) out of the 2l admitted patients and 7 patients(53.8%) out of the 13 OPD patients showed clearing. 2. In the case of the admitted patients, the mean numbers of therapy(days) of the improved patients reaching grade 4 were 12. 0(18. 1 days) in the trunk lesions and 15. 5 (22. 0 days) in the extremity lesions' and those of the cleared patients reaching grade 4 were 11. 2(16. 0 days) in the trunk lesions, and 13. 4(lg. 5 days) in the extremity lesions, but the difference was not significant statistically(pp o.ps). The difference between the therapeutic effects of the admitted and the OPD patients was significant statistically(p<0. 05). 3. There were some notable side effects such as staining, pruritus, and erythema, but there were no cases of therapy termination.

The delayed blanch is one of the most discussed but undecided facets of atopic dermatitis as yet. At present, they favor the theory that delayed blanch is due to vasoconstriction, but it is not obvious whether this is due to "true" vasoconstriction or to the blood vessels being narrowed by the surrounding exudative edema, resulted from vasodilatation and increased capillary per meability. We compared cutaneous response of severe atopic dermatitis with that of age matched non-atopic individuals after intradermal injection of acetylcholine by means of naked eye and laser Doppler flowmeter examination, control group showed flare and wheals while at,opy group resulted in delayed blanch in addition to flare and whealing. The results of laser Doppler flowmeter examination revealed that, as compared to baseline, atopy group showed statistically significantly increase in spite of delayed blanch. We suggested that the delayed blanch may be not due ta va.soconstriction but due to the vasadilatation and aceumulation of edema fluid.
