Fractures of the femoral neck in children are rare and usually the result of severe trauma. The femoral necks in children, in contrast to those of adults, have many anatomic and physiologic differences. Among the late complications encountered are avascular necrosis, coxa vara, premature closure of the proximal capital femoral epiphysis and nonunion. In spite of careful management, significant complication rate often results. Nine cases of fractures of the femoral neck in children which were treated at Yeungnam University Hospital from June 1984 to August 1987 were reviewed. The results obtained are as follows: 1. The main causes of fractures were traffic accidents (5 cases). 2. Among 9 patients, 6 were girls and 3 were boys. 3. According to the classification of Delbet and Colonna, the transcervical fracture (6 cases) was the commonest type. 4. 4 cases were treated by closed reduction and internal fixation, 3 cases were treated by open reduction and internal fixation. 2 cases were treated by skin traction and cast. 5. The results were analyzed according to Ratliff's assessment. 6 cases showed good results, and 3 cases showed poor results. 6. Early diagnosis and good fixation method seemed to be vital to prognosis.

The normal values of glycogen contents in skeletal muscles in commonly used experimental animals and men were studied. In addtion, this study was designed to know the relationship between amount of exercise and glycogen content in muscle, and to know the causes of species difference. Glycogen contents were determined in quadriceps, gastrocnemius, and triceps in mouse, rat, rabbit, and man. The results of this study as follows: The value of glycogen content in human skeletal muscle is significantly higher than that of experimental animals. The heavier the body weight of experimental animal, the higher the value of glycogen content in each muscle. The value of glycogen content in gastrocnemius is higher than that of quadriceps. The value of glycogen content in quadriceps is higher than that of triceps.

Seventy consecutive ipsilateral fracture of the femur and tibia in sixty-eight patients from December 1974 through December 1984 treated at Severance Hospital were analysed in clinical and radiological aspect. 1. Fifty-nine patients were male and nine patients were female. The male patients were more injured in the ratio of 6: 1. The avarage age was 34. 2. The main cause of injuries were traffic accidents; 59 patients. (86.8%). 3. The majority of the fractures were shaft fracture; for example, femur shaft 57% and tibia shaft 47%, The open fracture of the tibia was 34% and the femur was 17%. 4. There were 24 cases of concomitant fracture and dislocation of other sites. A fat embolism was disgnosed in 4% of the patients. Four patients had died one month after sustaining injuries. 5. Over-all, a good or excellent functional result was achieved in 76% of the patients treated with internal fixation of both fracture, 65% of the patients with intexnal fixation for the femur fracture only and 35% of the patients managed conservatively.

We report herein a case of polymorphic pemphigoid in a 65-year-old woman, who had one-year history of generlized polymorphic eruption with intensely pruritic excoriated vesicobiullous lesions and residual pigmentation. Face and oral mucosa were spared. The skin biopsy specimen showed a subepidermal blister containing many eosinophils. Linear deposition of 1gG and C3 along the basement membrane was noticed on direct irnmunofluorescerice. Polyclonal garnmopathy with a tendency of beta-gamma bridging and increased IgG, IgA and kappachain, was frund on serum protein electrophoresis and immunoelectrophoresis. Skin lesions were well coritrolled by a combined therapy of prednisolone(20 mg/d), dapsone(100 mg/d) and cyclophosphamide(100 mg/d) for 4 months. Direct immunofluorescence performed 11 rnonths after the cnmpletion of the therapy was negative.

The differential diagnosis of atypical mycobacteriosis caused by atypical mycobacteria (with the exception of Mycobacterium tuberculosis, Mycobacterium bovis, and Mycobacterium leprae) which are widly distributed in soil and water, from pulmonary tuberculosis is possible only when atypical mycobacteria are isolated and identified. In this investigation, attempts were made to isolate atypical mycobacteria from persons registered as tuberculosis patients in the Anyang Health Center in Anyang City, Kyungki province, Korea. Biological and biochemical tests were performed for the atypical mycobacteria isolated from these patients, also retrospective analysis of clinical and X-ray findings of the patients with bacteriologically confirmed atypical mycobacteriosis were done. The results can be summarized as follows; 1. 103 strains of mycobacteria were isolated among 334 sputum samples from patients. 2. Among the isolated mycobacteria, 10 strains (9.7%) were found to be an atypical mycobacteria and 93 strains (90.3%) were tubercle bacilli of human type. 3. On the basis of Runyon's grouping of atypical mycobacteria, there were 3 strains (30.0%) of scotochromogen and nonphotochromogen respectively, 4 strains (40.0%) of rapid grower, and no photochromogen. 4. By biochemical tests, 3 strains of scotochromogen were identified as Mycobacterium scroful-aceum (2 strains) and Mycobacterium szulgai (1 strain) 3 strains of nonphotochromogen were Mycobacterium avium-complex (2 strains) and Mycobacterium terriae (1 strain), and 4 strains of rapid grower were Mycobacterium fortuitum (3 strains) and Mycobacterium chelonae. 5. In drug sensitivity tests, all 10 strains isolated atypical mycobacteria showed resistance to various concentration of INH and SM and low concentration (10 mcg, 40 mcg and 50 mcg) of EB, TH, and CS, and were sensitive to only high concentration (20 mcg and 100 mcg) of EB, TH, CS, and RFP. 6. In analysis of clinical findings by the patients with bacteriologically confirmed atypical mycobacteriosis, it was found that clinical symptoms of these patients appeared not to be mild than those of patients with pulmonary tuberculosis. The patients with atypical mycobacteriosis had been treated for pulmonary tuberculosis for a long time and they showed no improvement.

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.
