The thickness of the glomerular basement membrane may vary not only in glomerular disease, but also in normal persons according to age and sex. But there has been no data on the normal thickness of the basement membrane in Korea. This study was designed to determine the glomerular basement membrane thickness as a reference value according to age and sex, in 50 cases of minimal change disease obtained from patients aged 2~67 years. Measurement of glomerular basement membrane was made on electron micrograph using an image analyzer. The thickness of each case was estimated by the arithmetic and harmonic mean methods. The mean thickness of the glomerular basement membrane was 291.9 47.9 nm by harmonic mean method and 284.2 43.7 nm by arithmetic mean method. And the harmonic mean thickness of the glomerular basement membrane according to age was 249.1 32.5 nm (1~5 years), 256.6 45.3 nm (6~10 years), 279.2 57.9 nm (11~15 years), 303.2 43.8 nm (16~20 years), 335.3 37.5 nm (21~30 years), and 291.1 22.5 nm (over 30 years), respectively. There was a trend that the thickness of glomerular basement membranes increased with the age till 30 years of age. There was no significant sex-related difference. In conclusion, the mean glomerular basement membrane thickness is comparable to the data from western people and shows a trend of increasing thickness according to the age.

We present 9 cases of plexiform schwannoma examined at Severance hospital from January, 1980 to September, 1987. The predilection sites of plexiform schwannoma included head and neck including oral cavity. The mean age at the time of diagnosis was 32 years. The difference of sex ratio was not apparent. Histopathological findings revealed multiple round to oval nodules encapsulated by thin fibroconnective tissue with nuclear palisading and Verocay body in each nodule. There was mild to moderate cellular atypia in some area, but mitotic figure was not found. The Bielschowsky's silver stain did not demonstrate any axon within or outside of the nodule. The thin capsule was positive with reticulin stain.

A 58-year-old female with an episode of gross hematuria two months before and fever and chill for the past three days presented oliguric acute renal failure. She has taken NSAID intermittently for 18 years due to rheumatoid arthritis, and herb medicine for one week two months ago when gross hematuria developed. Physical examination revealed mild tenderness on costovertebral angles. Her blood pressure was 170/100 mmHg, the urinalysis showed >300 mg protein with many RBCs and 10-20 WBCs and the serum creatinine was 5.8 mg/dl. A renal biopsy performed on the 4th hospital day showed that it was overwhelmed by severe tubular lesions which reveal intratubular obstruction by massive erythrocyte casts and tubular necrosis. The glomeruli showed focal minimal crescents with many red blood cells entrapped in the crescents and in the capillaries. Immune deposits were not present. A renal failure resolved spontaneously and the patient was discharged three weeks later with creatinine of 2.4 mg/dl. In this patient, acute renal failure was considered to be due to a tubular lesion related to the glomerular bleeding from focal glomerulonephritis revealing minimal crescents.

In 1983, Nora et. al. reperted 35 cases of bizarre parosteal osteochodromatous proliferations of the hands and feet. All lesions occured on proximal phalanges, metatarsals, or metacarpals. The gross appearance was typically that of a small osteochondroma. Radiologically, the proliferations lacked both central continuity of the tumor with the underlying osseus medulla and flaring of the adjacent cortices. Histologically, the lesion exhibited marked proliferative activity, irregular bohy cartilaginous interface, and enlarged, bizarre, and binucleate chondrocyte. The authors experienced a case of bizarre parosteal osteochondromatous proliferation of the right foot in a 61 year-old female which arised from the proximal phalanges of second toe, hostologic and radiologic findings were consistent with the bizarre parosteal osteochondromatous proliferation. The mass was treated by excision, and neither recurrence, nor malignant change was observed up to one year follow-up period.

Longitudinal growth acceleration of the femoral shaft after fracture in children has been recognized since the late nineteenth century, Orthopaedic surgeons have attempted to compensate for the leg length discrepancy by allowing union to occur with some degree of shortening, but logitudinal overgrowth following fractures of the tibial shaft in children has been rarely studied. Thirty-one children, treated for fracture of the shaft of tibia, were studied prospectively to assess the consequent increase in longitudinal growth of the tibia. The material presented in this paper is the result of the study of thirty-one children with fractured tibia who were treated in the Department of Orthopaedic Surgery of Kangnam Sacred Heart Hospital of Hallym University, since 1986 October, the age of the child varied from 3 years to 13 years, these cases have been followed from 30 months to 40 months. We have made a radiologic study of fracture of the tibial shaft with a view to analysing the results according to a number of factors, including the sex and the type, site and degree of overriding of fracture, and method of treatment, and then the degree of overgrowth was compared with unaffected side. 1. The average tibial overgrowth following tibial shaft fracture is 7mm. 2. Growth of the femur was not affected by the tibial fracture.
