BACKGROUND: Acne, one af the commonest dermatological disorders, is a disease of the pilosebaceous unit, and the primarily involved site is the face, where this structure exists in maximal density. Among the many etiologieal factors of acne, changes in the kinetics of sebum secretion in acne patients have been described, but there is no report to compare follicular density and the sebum excretion rate in different facial regions between normal and acne patients. OBJECTIVES: The purpose of this study was to compare the sebum output and follicular density in different regions of the face in women with and without acne and to evaluate the differences between the two groups. METHODS: We studied 10 normal and 14 acneic women aged 19-27. Follicular density was determined by light microscopy counting pilosebaceous units on cyanoacrylate follicular biopsy specimens. The sebum excretion rate was calculated by an image analyzer with a sebum print on Sebutape. RESULTS: 1. Follicular density was not significantly different between the normal and acne group. The number of follicles decreased from the central to the lateral aspect of the face with the highest value being on the nose tip and the lowest on the lateral forehead. 2. The total sebum excretion rate and the number of actively secreting follicles showed different patterns in the two groups. There was a decreased value in the acne group in some central regions of face. In addition, central to lateral declining pattems, shown in the normd group, were not apparent in the acne group. 3. The follicular sebum excretion rate showed large variations in both groups, without apparent central to lateral declining patterns. The confluence of adjacent follicles seemed to produce falsely low or high values compared with previous studies. CONCLUSION: Sebum production is influenced both by the number of active follicles and their individual capacity to excrete sebum, and the total sebum excretion rate was lower than normal in low grade acne in this study. Obstruction of the outflow of sebum and regression of sebaceous glands due to comnlones may account for it.

Pityriasis rosea is sometimes accompanied with considerable pruritus. Ultraviolet B irradiation is reported to be beneficial in relieving pruritus. The purpose was to evaluate the effect of UVB phototherapy on severe pruritus of pityriasis rosea. Nine patients with severe pruritus had UVB irradiation three times a week Five patients became symptom free and three showed a marked improvement. One dropped out. UVB phototherapy could be an effective modality for relieving pruritus in pityriasis rosea.

This study was to investigate the various parts of the mandible related to inferior alveolar nerve conductive anesthesia in 228 dry skulls of Korean adults. Five morphological variations were observed and four measurements were undertaken. The following results were obtained. 1. The Position of coronoid notch in the anterior border of the ramus of mandible is classified into three types and percentage of each type was as follows : Type I (Coronoid notch in the middle part of the anterior border of the ramus of mandible) : 83.3% Type II (Coronoid notch in the inferior part of the anterior border of the ramus of mandible) : 12.7% Type III (No coronoid notch in the anterior border of the ramps of mandible) : 4.0% 2. The position of the lingula of mandible to the imaginary line of the molar occlusal plane is classified into three types and percentage of each type was as follows : Type I (Above the imaginary line of the mandibular molar occlusal plane) : 87.3% Type II (Coincide with the imaginary line of the mandibular molar occlusal plane) : 8.6% Type III (Below the imaginary of mandibular molar occlusal plane) : 4.3% 3. The position of the lingula of the mandible in the internal oblique line-posterior border of the ramus of mandible dimension is classified into three types and percentage of each type was as follows : Type I (Anterior part in the internal oblique line-posterior border of the ramus of mandible dimension) : 82.9% Type II (Middle part in the internal oblique line-posterior border of the ramus of mandible dimension) : 11. 4% Type III (Posterior part in the internal oblique line-posterior border of the ramus of mandible dimension) : 5.7% 4. The position of the apex of the lingula of mandible to the deepest point of the coronoid notch in the anterior border of the ramus of mandible is classified into three types and percentage of each type was as follows : Type I (Coincide with the deepest point of the coronoid notch) : 82.0% Type II (Above the deepest point of the coronoid notch) : 13.2% Type III (Below the deepest point of the coronoid notch) : 4.8% 5. The position of the apex of the lingula of mandible to the imaginary line of the mandibular molar occlusal plane is classified into three types and percentage of each type was as follows : Type I (Above the 8mm) : 65.7% Type II (Above the 5mm) : 18.6% Type III (Above the 10mm) : 15.7% 6. Angle between the line connecting the apex of the lingula of mandible-1-2 premolars in the contralateral side and median line of the mandible is classified into three types and percentage of each type was as follows : Type I (50°) : 67.2% Type II (45°) 21.4% Type III (55°) : 11.4% 7. The averages of the measurement of the various bony landmarks of the mandible related to inferior alveolar nerve conductive anesthesia were as follows : ① Distance from deepest point of the coronoid notch to internal oblique line : 9.2mm ② Distance from internal oblique line to the apex of the lingula of mandible : 11.6mm ③ Distance from deepest point of the coronoid notch to apex of the lingula of mandible : 19.7mm ④ Height of the lingula of mandible : 9.8mm

This study was undertaken to know whether the UV-irradiation of the skin causes changes in the superoxide dismutase(SOD) activities. After shaving, the back skin of the rabbit was irradiated with UV light ranging from 280 to 320 nm of wavelengths from Burdick lamb (UV800) in doses of either 0.5, 1.0 or l.5 J/cm2. The skin was removed imrnediately after irradiation and the enzyme activity was assayed by the method of McCord ad Fridovich (xanthine-xanthie oxidase system), One unit of the SOD activity was defined as the amount of the enzyme required to inhibit the rate of reduction of cytochrome c by 50%. The protein content of the enzyme was determined by biuret method. The SOD activity of the skin irradiated with 1.0 J/cm was 7. 78 + 1.62 unit/mg protein(Mean+SD; n=10), significantly higher than that of the control(nonirradiated) group(5.62+1.57 unit/mg protein; n=l0). No significant changes were found in the skins irradiated with 1.5 and 1.5 J/cm. This finding indicates that UV irradiation is capablc of increasing the SOD activitiea in the rabbit skin, and suggests that increased superoxide formed by UV irradiatiun induces the increased SOD activies.

During a 10-year period from Jan, 1970 to Dec. 1979, 33 cases of systemic lupus erythematosys were observed clinically at the Department of Dematology, Chonnam University Hospital. Statistieally, 13 cases were male and 20 chses firnale for a sex ratio of 1: l. 5. The most common age group at eatimated onset was 10-19 and the mean age was 27, 3. There were 5 cases under the age of 15 comprising 15. 2, of all cases. There was no seasonal variation at the onset of disease. Facial lesions were the most common initial sign or symptom and chief cornplaint. During the course of the illness, varions manifeatations were obaerved: artbralgia, 87. 9%; weakness and fatigue, 84. 8%; fever, 75. 8%; cutaneous lesions, 100. 0% gastrointestinal symptoms, 54. 5%; pulmonary symptoms, 42. 4%; cardiae abnomalities, 36. 4%; enlargement of reticuloendothelial systems, 30.3%; and neuropsychiatric symptom., 30. 3%. Upon laboratory analysis we found 14 cases of lupoid hepatitis and 8 cases of lupus nephritis. There were various associated diseases such as retinopathy, congestive heart failure, pulmonary tuberculosis, diabetes mellitus, etc.

Epdemiological studies were done on 721 patients detected and confirmed as leprosy patients at the Department of Dermatology at Chonnam University Hospitai in the ten years period from l969 to 1978. Statistically, 491 cases were male and 230 cases were female, comprising 2. 1% of the total number of outpatients (34, 631) and showing a decreasing yearly tendency, The percentage of each group, or type; tuberculoid, borderline, lepromatous and indeterminate, was 53.8%, 9.6%, 31.2%, and 5.4%, respectively. The most common age at discovery for males was 30 39 and for female 20~29 with the largest group being adults aged 20~49, 482 cases (66.9%). The sex ratio was 2.1: l, male to female. However, for the tuberculoid types the ratio was 2.5: 1 which was higher than that of the lepromatous type, I. 7: 1, By disease type the most common age group was 20 29 for tubercekid type, 30 39 for lepromatous and borderline group and 10~19 for the indeterminated group. Geographically, 652 cases(90. 4%) were from Chonnam Province and 61 cases (8.5%) from Chonbuk Province. We also observed some significant sequential changes of the type of disease descovered even though 10 years is a relatively short period. There was a tendency towards decreased detection of the tuberculoid type and increased detection of the borderline an.d indeterminate group.
