Thoracic kyphosis was measured on chest lateral radiographs of 885 normal subjects, comprising of 509 males and 346 females. Subjects were accepted as normal if they had no problems of lung, heart of spine such as scoliosis or significant compression fracture radiologically. Kyphotic angle was measured by Cobbs method from T3 to T10. Index of wedging which represents the wedging degree of vertebral body was measured on apical vertebra, and also the location of apical vertebra was studied. The results obtained were as follows: 1. Kyphotic angle through all age groups showed the range 17°–33° in males and 17°–34° in females. 2. Kyphotic angle increased with the increase of age, but not related with sex. Therefore normal range of kyphotic angle should be determined in respective age group accordingly. 3. Index of wedging in apical vertebra through all age groups showed the range of 1.07–1.21 in males and 1.07–1.23 in females. 4. Index of wedging increased with the increase of age, and normal range of index of wedging in respective age group was supposed to be more significant. 5. There was no correlations between the regression of kyphotic angle and index of wedging. 6. The most frequent apical vertebra was located on T6, and then T7 and T5 in order.

Progressive cribriform and zosteriform hyperpigmentation (PCZH) is a distinctive clinical entity first described by Rower et al. in 1978. It is characterized by a single area of uniformly tan cribriform macular pigmentation in a zosteriform distriggtjpp with no preceding history of skin rash, injury or inflammation. It begins well after birth with gradual extension and is not associatad with any other cutaneous or internal abnormalities. Histologically, there is a mild increase in melanin pigment in the basal cell layer and complete absence of nevus cells. Recently, we observed clinical and histological featurea of 5 cases of PCZH. The age at onset ranged from 4 to 35 years. The lesions were unilaterally distributed on face, neck, chest, or abdomen. Histologically there was a mild increase in melanin pigment in the basal cell layer. PCZH must be differentiated from Beckers hairy nevus which begins with a unilateral lesion of irregularly macular pigmentation but occasionally it may be multiple or bilateral. In early stage, overgrowth of hairs may be absent but after a few years it is usually present. PCZH is characterized by uniformly tan cribriform pigmentation in zosteriform distribution, which is unilateral and does not cross the midline of the body. Overgrowth of hairs is absent even after a few years. So the lesions of Beckers hairy nevus previously reported, which were unilateral and did not cross the midline of the body and did not show overgrowth of hairs even after a few years, must be called progressive cribriform and zosteriforrn hyperpigmentation.

Congenital pulmonary lymphangiectasis is a rare cause of severe respiratory distress in the newborn period and most of these patient die, usually within the first 24 hours of life. The light microscopic characteristics of the lungs are a network of partly tubular, partly cystically enlarged lymph vessels within large areas of connective tissue and they have thin wall lined by endothelium. Also congenital pulmonary lymphangiectasis is closely associated with cardiovascular malformation, and most frequently occurs in the clinical setting of congenital heart disease with or without pulmonary venous obstruction(total anomalous venous return, atresia of large pulmonary veins) The authors describe three typical cases of congenital pulmonary lymphangiectasis.

This study was a part of large scale of a prospective study on attitudes of professional students in medicine, nursing and teaching toward population related issues in Korea. The study was first conducted in May 1974 and then in May 1975 for the 1974 class cohot using a questionnaire consisted of attitude scales and other items developed by Lee. The purpose of study was two hold, namely, to determine the difference in students among specializations on one hand and between the first and second years in the 1974 class cohot regarding the subject matter. A one-way analysis of variance was used for attitude scale, and absolute and relative frequency were computed for the analysis of non-attitude scale items by employing Fishers' Ratio and Duncan's multiple range test at 5% level and chi square test at 5% level as significance tests. The hypothesis "students in health profession are more likely to have positive attitudes toward population related issues progressively as class year advances than students in teaching profession" was tested and the following results were obtained: 1) Nursing students were more likely to display favorable attitudes toward family planning than medical or teaching students although the class cohot showed slightly improved attitudes in the second year. 2) Respondents in general perceived national family planning program as a means of population control and this tendency was more true among nursing students as the class year advances than two other professional groups of students. Students in teaching profession appeared to perceive it more as a means to improve individual family welfare while health students were likely to see as to improve maternal and child health. This tendency was progressively improved as the class year advanced. 3) The majority of students regardless of their respective specializations believed that family planning program should be directed toward the improvement of individual family welfare. No progressive changes in the class cohot were observed. 4) About the plan to use contraceptives in future, no significant differences were observed among different specializations nor in different class years. However, the majority was confirmed to have a plan to use contraceptives in future. An increasing proportion of the undecided category was observed, as class year advanced among health students. 5) Students in health profession were found to be more favorable about "more leisure opportunities" as motive for limiting number of children whereas education students indicated the reasons as "facilitate ambitions" and "economic base". The progressive changes toward positive direction in both groups were observed as the class years advanced. 6) Attitudes toward induced abortions of the health student were observed to be positively related to class years while an inverse relationship was found in teaching students who showed much less favor in the subject matter than health students. This phenomenon may be due to the different exposure to learning environments unique to respective specializations. 7) Health students were found to have more favorable attitudes toward population education in general than the teaching students. The teaching students appeared to have changed more to the negative direction when they became the second year while no such development was observed in health students. The teaching students seemed to hold a very conservative position with regard to sex education on schools. 8) About the equality of sexes, the nursing group was found to be most favorable while the reverse was true in the teaching group. 9) About questions related to fertility values-the 10 percent of respondents regardless of specialization indicated that they would maintain their single status in future, however no change was observed in the second year. The desired number of children was found to be two by the majority of students in nursing, medicine and teaching in order of high proportion. No changes in a different class year were observed. The childless marriage was seen by nursing students as a problem more than other students, but a slight change in positive direction was found when the nursing students became the second year. In summing, as data supported in the above, students in health profession demonstrated more favorable attitudes toward population related issues than the teaching students were more conscious about the health aspect of population and family planning program while the teaching students gave more attention the socioeconomic aspect. The sex variable seemed to have operated in the item related to the equality of sexes. In conclusion, as data presented in the above, the hypothesis of this study was accepted except in the few items. It should be noted that the limitation of this study is the short duration of the observation in measuring the possible attitude changes. It should include curriculum analysis for the respective specializations in order to identify the area of curriculum impact on students in future study.

A black pigmented ulcerative, 1cm x 3cm nodule was developed in a 43 year old woman since 5 years ago. Clinically, it resembled the malignant melanoma and histopathological study revealed the combination of pigmented and morphea like basal cell epithelioma. Wide and deep excision down to oral mucosa with frozen section of free margin and primary closure had performed to bring the excellent cosmetic outlook, Both the pigmented basal cell epithelioma and morphea like basal cell epithelioma are reported rarely, however, to the best of our review of the English literature, this is the first of reported case of combinated type of pigmented and morphea like basal cell epitheliorna. We are now on close observation of the patient for recurrence and metastasis of the tumor.

Lymph nodes, one of peripheral lymphoid organs, are the sites, where the lymphocytes receive their initial instructions for producing effector functioning resulting in humoral or cell-mediated immunity. Each lymph node consists of an outer cortex in which there are aggregates of cells constituting the follicles, B-cell areas. Some follicles have central areas called germinal centers, which stain lightly. Germinal centers are B lymphoblast cell areas arising eccentrically in primary lymphoid follicles in response to T-cell dependent antigenic stimulation and are the generally accepted sites of generation of memory B cells and undergoing isotype switching and somatic mutation. We observed the morphologic, cellular, protein and molecular events arising in mouse popliteal lymph nodes in response to T-cell dependent antigenic stimulation. In this study mice were immunized into footpads with TNP-chicken ovalbumin. The germinal center formation in primary follicles of popliteal lymph nodes was first observed 6 days after immunization and germinal centers persisted until 24 days of immunization. Lymph node cells were stained with PE-labeled anti-B220 antibody and/or FITC labeled PNA and analyzed by using FACScan. B cells (B220(+) cell) in lymph node increased after 3 days and peaked between 6 and 18 days after immunization. The proportion of germinal center B cells (B220, PNA(high) cells) among lymph node B cells was low (2%) before immunization but increased at day 6 (9%) and reached the peak (30%) at day 18. The expression of IgG1 productive mRNAs and germline transcripts were observed by using RT-PCR. The expression of IgG1 productive mRNA was detected at day 10 and continued until 24 days after immunization. The expression of IgG1 germline transcripts was observed 10 days after immunization and rapidly declined over the next one week. IgG1 anti-TNP antibody, main isotype of anti-TNP antibodies, was first detected at day 14 and reached the peak level 24 days after immunization. Taken these data together, we can conclude that the first immunological event observed from mouse popliteal lymph node in response to T-cell dependent antigenic stimulation is the increase in the number of B cells, and this event is followed by appearance of germinal center B cells and at the same time by the formation of germinal center in primary lymphoid follicles. Once the germinal center is formed, the process of isotype switching to IgG1 occurs in lymph node and antigen-specific IgG1 antibody is produced.
