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.

The study was performed to measure and compare the peripheral blood T cell and T subsets in normal controls and psoriatic patients. Thirty-two normal controls and fift:en psoriatic patients were subjected to the study and the percentages and the rati vs of peripheral blood T cell and T subsets were measured. The results were as follows: 1. Mean percentages of peripheral blood lymphocytes reactive with OKT3 monoclonal antibody in psoriatic patients were 72. 8+-8. 2%, They decreased significantl) as compared with these in control group(76, 6- i-4. 7%). Mc an percentages of peripheral blood lymphocytes reactive with OKT4 monoclonal antibody in psoriatic patients were 47. 3+6, 7p;. They increased as compared with these in control group(46. 5+-3. 9p;), but the increase was insignificant. 3. Mean percentages of peripheral blood lymphocytes reactive with OKT8 monoclonal antibody in psoriatic patients were 27. 2+5. 5g, They decreased significantly as compared with these in control group(30, 6- l-4. 3%) 4. Mean ratios of lymphocytes reactive with OKT4 monoclonal antibody to these reactive with OKT8 monoclonal antibody in psoriatic patients were 1.8+- 0. 48 They increased significantly as compared with these in control group(1. 6+ 0.34).

Juvenile xanthogranuloma is characterized by one, or oftener many, yellow, re3dish yellow, or, brown 4-to-20 mm papules or nodules on the face, scalp, trunk, and mostly, extensor surfaces. It may involve internal organ besides the skin such as eye, gastrointestinal and genitourinary tracts. anthogranuloma in adult is usually solitary and dose not involve organs other than skin, and generally dose ncit resolve without treatment. Histopathologically, characteristic Touton giant cells usually appear numerously. We report a case of juvenile xanthogranulorna which occured on scalp of 49 year-old male showing typical clinical and histopathological findings.

Cutaneous horn is a clinical term for a circumscribed concial hyperkeratotic mass amounts to at least half of its largest diameter. The number of lesion may be single or multiple. We report herein a cases of penile cutaneous horn in a 22-year-old male. He had dark brownish colored conical shaped protruded mass on the penile shaft for about 2 months. We performed excisional biopsy and curettage. Histopathologic findings showed verruca vulgaris.
