Accurnulation of keratinized cells within the infundibulum of pilosebaceous canal is important in the pathogenesis of acne. Light and electron microscopic study of experimentally induced comedones, from the rabbit's external ear canal, was performed to define the earIy morphologic changes within and around the epithelial lining of the comedones. In light microscopic observation, early comedone was composed of loose cohesive horny cells and late comedone was composed of a mixture of loose and tight cohcsive horny cells. Cohesion between horny cells occured, in eIectron microscopic study, in two different ways: initially, by the persistence of desmosomes; later, and to a lesser extent, by tight junctions, which tightly bound the horny cells together. Multiple lipid droplets within the horny ceIls and a gradual decrease in the numbrane coating granules were observed.

Oak moss is a lichen extract obtained from Evernia prunastri and Pseudovernia furfuracea. It is the potent,ial allergen in contact dermatitis to perfumes. Sensitivity to oak moss has been atributed mainly to atranorin, evernic acid, usnic acid and fumarprotocetraric acid. We report a 44-year-old female patient presenting with features of contact dermatitis due to oak moss in perfumes. Patch test results revealed positive reactions to fragrance mix, oak moss, atranorin and evernic acid.

Authors examined the morphology and size in the maxillary lateral insicor from Korean adults and the following conclusion have been drawn. 1. In the shapes of labial surface in maxillary lateral incisors, the quite prominent middle lobe, moderate prominent middle lobe, less prominent midd1e lobe were 20.60%, 69.85%, 9.55%, respectively. 2. In the shapes of incisal margin in maxillary lateral incisors, the arc shaped to the distal, round, nearly straight were 24.96%, 60.20%, 15.11%, respectively. 3. In the shapes of incisal angle in maxillary lateral incisors, the equal sized mesioincisal angle and distoincisal angle, larger distoincisal angle, much larger distoincisal angle were 8.36%. 67.34%, 24.30%, respectively. 4. In the shapes of lingual surface in maxillary lateral incisors, the marked shovel (Ms), semi-shovel (Ss), trace shovel (Ts), no shovel (No) were 43.00%, 33.50%, 19.50%, 4.00%, respectively. 5. The size of the maxillary lateral incisors were as follows. 6. In comparison with Wheeler's data, crown length, crown width and crown thickness were larger in Korean adult, but the degree of cervical curvature were smallest.

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.

Various parameters obtainable from the M-mode echocardiograms were determined in 100 healthy young males, and a comparative study of the data with those of the previously reported was made. It was found that our data as a whole were in general agreement with the others.

We report a case of molluscum contagiosum occurring in an epidermal cyst. A-38-year old male patient had the lision which was a 1.2 x 1cm sized, elevated, round nodule on the right cheek. Histology showed true epidermal cyst containing molluscum bodies throughout the cyst wall and laminated keratotic material within the cyst itself.

PURPOSE: This research is to know whether aroma foot massage has influence on the relief of anxiety and pain during colonoscopy under conscious sedation. METHOD: This research was designed as a quasi-experiment of non-equivalent control group pretest-posttest. Data were collected from April 1 2005 to August 30 2005. The subjects were divided into three groups (control group, foot massage group and aroma foot massage group) with 30 persons each. Anxiety was evaluated with Visual Analogue Scale (VAS), blood pressure and pulse. Pain response was measured with VAS and non-verbal pain behavior score. Sleep satisfaction was measured with a graphic rating scale. Data were analyzed through Chi-square test, t-test and repeated measure ANOVA. RESULTS: Systolic blood pressure, pulse, subjective anxiety and pain scores from the aroma foot massage group decreased significantly. Sleep satisfaction score of the aroma foot massage group increased significantly. Diastolic blood pressure from the aroma foot massage group did not decrease. CONCLUSION: The results show that aroma foot massage with refined oils can increase sleep satisfaction and decrease anxiety and pain during colonoscopy under conscious sedation.

Multiple trichoepithelioma is an uncommon skin disease with autosomal dominant transmission. A 21-year-old female ahd asymptomatic, flesh-colored, firm papules and nodules on the face, chest and back. Histopathologic examination showed multiple horn cysts and tumor islands composed of basaloid cells.

Localized primary cuteneous nodular amyloidosis is the rarest form of the cutaneous amyloidosis, which appears as single or multiple nodules on the extremities, trunk, genitalia or face. A 44-Year-old woman had asymptomatic, translucent brown to pink papules and nodules on the toes for 5 years. Histopathologic exarnination showed deposition to pale, eosinophilic, amorphous material throughout the dermis, Under the electron microscope, the material consisted of straight, nonbranching, nonanastoimosing filaments. We thus made the diagnosis of nodular amyoidosis.
