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.

In almost all biologic systems, mechanically induced electric charge separation is a fundamental phenomenon. Since the hypothesis was established that the generation of electric potentials in bone by mechanical stress including muscular force might control the activity in bone by mechanical stress including muscular force might control the activity of osseous cells and their biopolymeric byproduct, the concept of electrically mediate growth mechanism, which involves biological growth and bone remodeling by any means, in living systems has been applied clinically and experimentally to orthopedic fracture repair, the regulation of orthodontic tooth movement, epiphyseal cartilage regeneration, etc. On the other hand, recent numerous research data available show apparently that the mandibular condyle has the characteristics of growth center as well as growth site. In addition, there exists a considerable difference of opinion as to the role of external pterygoid muscle in condylar growth. In view of these evidences, this. experiment was performed to investigate the effect of the galavic current on the growth of the mandible and condyle for elucidating the nature of condylar growth. The bimetallic device was composed of silver and platinum electrode connected with resistor (3.9 Mohm), which was expected to produce galvanic current of 23.6 nA according to the galvanic principle. The 25 Sprague-Dawley rats were divided into two group, 2 week group comprising 8 animals exposed to galanic current for 2 weeks and 3 control animals not exposed for 2 weeks, 4 week group comprising 10 animals in experimental group and 4 animals in control group applied for 4 weeks respectively. The experimental rats were subjected to application of the galvanic current invasively to codylar head surface and the control groups with sham electrode. On the basis of anatomic and histologic data from the mandibular condyle of experimental and control group, the following results were obtained. 1. After 2 weeks, there was no increase of mandibular size in experimental group over that of the control group. 2. After 4 weeks, the size of the condylar head was larger in experimental group than that of the control. 3. In 2 week group, the thickness of the mitotic compartment and hypertrophic chondroblastic layer was increased in experimental group. 4. In 4 week group, the number and the size of the hypertrophic chondroblasts were increased significantly on experimental group over that of the control group. 5. The application of the galanic current caused an increase in chondrocytic hypertrophy and intercellular matrix in both groups.
