A clinical and histological study of typical sebaceous epithelioma (basal cell epitheioma with sebaceous differentiation) developed secondarily in lesions of nevus sebaceus of Jadassohn is presented. The patient was 42 years old male. The sebaceous epithelioma tends to have about the same clinical characteristics as undifferentiated basal cell epithelioma but it is more often a yellow color. Sebaceous epitheliova may arise from nevus sebaceus and it is preursor of undifferentiated basal ce]1 epithelioma. Histological]y, the preparation showed massive development of sebaceous gland, papillomatous epidermal hyperplasia and maturation of apocrine glands. The tumor cell nests were mostly composed of large sheets of irregularly shaped cells in palisading pattern at the periphery. There were Iarge number of cells with vacuolated cytoplasm resembling sebaceous cell in certain part of the tumor cell masses and several keratin pearls. Diagnosis confirmed by clinical appearance and histological picture. These lesions could be treated sucessfully by wide excision.

The primitive erythroblasts in 21 cases of embryonic hearts from 4 to 9 weeks of gestation were studied with a light microscope. The nuclear diameter, the motosis, and the loss of nuclei of the primitive erythoblasts were analyzed quantitatively. The results obtained were as follows. 1. At 4 weeks of gestation, the blood cells consisted of proerythroblasts, along with basophilic polychromatophilic primitive erythroblasts. The nuclear diameter ranged from 3.20 µm to 9.20 µm, but the main range was from 4.20 µm to 6.00 µm. It was revealed that 9.50% had diameter of more than 6 µm. 2. At the fist half of the 7 week gestation when hepatic hemopoiesis developed, the blood cells consisted of basophilic, polychromatophilic, and eosinophilic erythroblasts. Cells of more than 6 µm in nuclear diameter were about 1.10% and thereafter gradually disappeared. The range of the nuclear diameters was from 2.60 µm to 7.00 µm, while a range from 3.40 µm to 5.20 µm wqs the main. The proportion of cells less than 4 µm in nuclear diameter was 39.58% and thereafter rapidly increased. 3. From the second half of 7 weeks to 9 weeks of gestation, the erythrocytes originating from hepatic hemopoiesis increasingly replaced the circulating primitive erythroblasts, which became mature during this time. The erythrocytes showed 72.88% at 9 weeks of gestation. The proportions of cells less than 4 µm in nuclear diameter in the first and second haIves of 8 weeks and 9 weeks were 52.73%, 80.02%, and 89.09%, which represented the rapid destruction of nuclei. 4. Mitosis in the primitive erythroblasts occurred principally up to the early 6th weeks, and very weakly at 8 weeks. 5. As the crown-rump length increased, the average nuclear diameter decreased very significantly (P<0.01, y=-0.2811X + 0.3171). The results suggest that distrilbution of the nuclear diameter, the maturity, the rate of nuclear loss, and the mitotic figure offer credible data for estimating embryonic age.

The stature, span, lower limb length, sitting height, head length and head breadth of 411 Korean elementary school girls ranging from 7 to 10 years of age were measured biometrically and the indices among all of the items were calculated to investigate the physical growth status. The following conclusion have been obtained. 1. The average statures were 117.40cm in 7, 122.72cm in 8, 126.76cm in 9 and 132.92cm in 10 years of age groups, and the annual average stature growth was 5.17cm. 2. The average spans were 113.12cm in 7, 118.70cm in 8, 124.26cm in 9, 130.46cm in 10 years of age groups, and the annual average span growth was 5.78cm. 3. The average lower limb lengths were 62.96cm in 7, 66.80cm in 8, 69.09cm in 9 and 73.13cm in 10 years of age groups, and the annual average lower length growth was 3.39cm 4. The average sitting heights were 65.82cm in 7, 68.56cm in 8, 70.18cm in 9 and 73.13cm in 10 years of age groups, and the annual average sitting height growth was 2.43cm. 5. The average body weights were 21.22kg in 7, 24.13kg in 8, 25.54kg in 9 and 29.27kg in 10 years of age groups, and the annual average body weight growth was 2.68kg. 6. The average head lengths were 16.29cm in 7, 16.38cm in 8, 16.47cm in 9 and 16.60cm in 10 yeras of age groups, and the annual average head length growth was 0.10cm. 7. The average head breadth were 14.50cm in 7, 14.65cm in 8, 14.67cm in 9 and 14.81cm in 10 years of age groups, and the annual average head breadth growth was 0.10cm. 8. While both relative span and lower limb length increased with age and the relative sitting height slightly decreased with age. 9. The relative body weight increased with age. 10. The head type depended on cephalic index was belonged to hyperbrachycephaly, and showed no differrences with age in all of the groups. 11. The relative span was over 96 in all age groups, and the value increased slightly with age. 12. The average annual growth showed remarkable high value between 9 to 10 years of age in the items of stature, span, lower limb length, sitting height and body weight.

Lidex' cream (Fluocinonide 0.05% in FAPG base) is a new fluorina,ted topical corticosteroid, and its clinical effect was assessed by applying topically three to four times daily to the lesions of 50 patients with a variety of inflamrnatory skin condi- tions. The results revealed excellent effect in 16 patients, moderate effect in 23 patients, slight improvement in 9 patients, and no effect in 2 patients. No unfavorable side effects were noted except blanching. The findings suggest that fluocinonide is an excelIent addition to the topical corticosteroid agents that are available for clinical use at the present time.

Although the psoralen therapy has been used extensively on vitligo since the : introduction by El-Mofty on 1948, the result has not been satisfactory. Recent investigations showed that the autoimmune mechanism might be the causative factor to the development of vitiligo, and the use of steroid might be expected to be beneficial in the treatment of this disorder. Authors tried the combined treatment of prednisolone and psoralen on vitiligo and the results obtained are as follows; 1. Repigmentations began to develop from injected area of prednisolone as well as frorn hair follicles and peripheral area of the lesions. 2. More satisiactory responses were obtained on the widespread and symmetrical lesions of shorter duration than on the lesions of localized and long duration.

PURPOSE: We examined the effect of induced interocular difference of retinal illuminanace on stereopsis. METHODS: Fifty adults who have normal binocularity were examined with neutral density filters. The mean age was 29.1 years. While the monocular retinal illuminance was gradually reduced by increasing the value of neutral density filters, we measured the best corrected visual acuity and stereoacuity with Titmus test and Lang test. We used neutral density filter from 1.0 neutral density (ND, 10% transmit) to 3.0ND (0.1% transmit) with intervals of 0.2ND. RESULTS: The best corrected visual acuity began to decrease significantly when the value of neutral density filter reached 2.0ND (1% transmit). Stereoacuity also began to decline when the value was 1.4ND(4% transmit) with Titmus test and 1.6ND (2.5% transmit) with Lang test. CONCLUSIONS: Change of retinal illuminance effects more on stereoacuity than visual acuity as stereoacuity decreased earlier by increasing the value of density filters. These results imply that the stereopsis test could be more useful than visual acuity test for detecting ocular abnormalities influencing the retinal illuminance.
