The model of lymphocyte differentiation described for Lukes-Collins' classification of non-Hodgkin's lymphoma is related particularly to morphological alterations of nuclei of follicular center lymphocytes by antigenic stimulation. The authors carried out ultrastructural and morphometric studies to investigate morphological alterations during lymphocyte transformation on the nuclear profiles of follicular center, parafollicular and mantle zone lymphocytes in ten tonsillectomy cases of chronic hypertrophic tonsillitis. The nuclear parameters measured included nuclear area, contour index, frequency invagination and cleft, depth of invagination and nuclear diameters. Follicular centers contained a mixed population of lymphocytes consisting of untransformed (type 1), partially transformed (type 2) and fully transformed (type 3) lymphocytes. During lymphocyte transformation in both follicular, and parafollicular and mantle zones, the nuclei had a gradual and progressive increase in size. The nuclear contour index of type 2 nuclei of both follicular and parafollicular and mantle zones tended to be higher than those of type 1 and 3, indicating a greater degree of irregularity and variability of nuclear profiles. Invaginated and cleaved lymphocytes were not confined to me transformed lymphocytes. A considerable portion of lymphocytes had invaginations and clefts in parafollicular and mantle zone as well as follicular center. No difference on the depth of invagination was noted in type 1, type 2 and type 3 lymphocytes. The results indicate that some promise of the Lukes-Collins conepts of follicular center cells and the process of lymphocyte transformation in follicular centers may be necessary to revise

Pearly penile papules are small, smooth, dome-shaped, grayish to skin-colored papules, that are arranged in one or several rows. These are commonly located circumferentially on the corona and sulcus of the glans penis. A 36-year-old male patient had had asymptomatic numerous pearly smooth 1 * 1mm -sized dome-shaped papules for several months. A Histopathological examination revealed an increased number of fibroblasts on the papillary dermis, vascular proliferation and a mild lymphocytic infiltration. We diagnosed the condition as pearly penile papules. No treatment other than reassurance was given. We report, herein, a case of pearly penile papules.

The surgical correct1on of blepharoptosis is accomplished by utilizing certain materials, the levator, the frontalis or the superior rectus muscle. The perfect postoperative results are complete cover of the eye on lid closure, adequate mobility when blinking, normal lid fold and no diplopia. The authors obtained good results in two children of congenital ptosis by attaching medial one third of superior rectus muscle to lid margin which was reported by Motais in 1897. The operation which use the superior rectus muscle is not favored recently because of complicationals such as partial corneal exposure, vertical diplopia, difficulty in blinking, and partial obliteration of the upper conjunctival fornix. But, the results of these simple physiologic proceures for binocular paralytic ptosis were remarkable without any complications as the aboves for 3 months of follow up check.

The authors reviewed 1134 pediatric patients in the ebergency room in this hospital during 5 years period from Jan. 1979. to Dec. 1979. The results were obtained as follows: 1) Among the patients visiting the emergency room, the patients under 15 years of age were 6.1%(1134) of total emergency patients(18447). 2) The male to female ratio was 1.5:1. 3) The highest age group was in the 3-5 years, and the patients in this age group were occupied 23.8%. The age distribution showed that 57.7% was under the 5 years of age. 4) Seasonal distribution of patients showed high incidence in summer(June, July, and Aug.). 5) The most popular time of visiting the emergency room was between 8:00 P.M. to 12:00 P.M. at which time about 32.8% of patients were seen. 6) Distribution of cases as follows: Respiratory disease 35.7%, accident 177% and gastrointestinal disease 14.8%, in turn, kusted reseoectuvely in decresing order of frequency. URI was the most frequency, 25.1% of the total cases, The next diseases were diarrhea(9.5%), Bronchitis(6.6%) and febrile convulsion(6.3%) in turn decreasing order. 7) The most frequent case in various age groups was Respiratory disease. 8) Admission rate of total pediatric patients visiting ER was 7.4% by recommendation. Rate against recommendation of admission was 3.2% of total pediatric patients visiting ER. 9) We think the number of pediatric emergent patient is increasing due to understanding of community inhabitant.
