Primary pulmonary tuberculosis is one of the common pulmonary disease affecting children in Korea. Simple chest film is essential in diagnosis of primary pulmonary tuberculosis, but it is difficult to interpret the findings in some cases. Authors reviewed chest films of 162 cases of clinically confirmed primary pulmonary tuberculosis from April 1978 to June 1981 at Seoul National University Hospital. The results are as follows; 1. Lymph node enlargement, either hilar or mediastinal, was found in 82.7% and pulmonary parenchymal infiltration in74%. 2. Incidence of unilateral and bilateral hilar lymph node enlargement is about 50% (81cases) and 30% (49cases) respectively. Incidence of unilateral and bilateral mediastinal lymph node enlargement is about 21% (34cases) and 4.3% (7 cases), more common in right side. 3. Pulmonary parenchymal lesion is demonstrated in 74% (120cases). The pattern of primary focus is as follows in order; patchy infiltration 47% (76 cases) linear-streaky infiltration 15% (25 cases), lobar or segmental homogenous infiltration 9% (14 cases), nodular infiltration 4% (7cases). The primary focus of right lung is two times as common as that of left. 4. Calcification in primary focusis noted in about 27% in pulmonary parenchyma and 49% in hilum. 5. Plerual effusion is identified in 10%, but pleural effusion without pulmonary parenchymal lesion or lymph node enlargement is noted in only 2% (3 cases).

BACKGROUND: Dermal papilla cells, which are mesenchymal components of the hair bulb are considered to play an important role in the regulation of hair growth by production of diffusible factors that stimulate follicular epithelial cells. Degenerative changes in the dermal papilla cells in the involved scalp of alopecia areata cases indicate that these cells are one of the important targets in this disease. OBJECTIVE: We investigated the effects of serum from alopecia areata patients on the proliferation of dermal papilla cells. METHOD: Dermal papilla cells and fibroblasts from normal human scalp were cultured in DMEM media with 10% or 20% of normal and alopecia areata serum for 48hrs and 96hrs. Cell proliferation was measured by cell counts and [3H]-thymidine incorpoartion. RESULTS: Both 10% and 20% alopecia areata serum had no significant effects on the proliferation of dermal papilla cells and fibroblasts after 48hrs and 96hrs. CONCLUSION: These results suggest that there are no serum factors that inhibit the proliferation of dermal papilla cells.
