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.

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.

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.

Cardiovascular measurement on PA teleroentgenogram of the chest is simple, but very useful in the diagnosis,prognosis, and therapy of hypertensive patients. The authors have measured and calculated cardiothoracic ratio,Lt, to Rt. cardiac diameter ratio, and Lt, aortic knob width to thoracic diameter ration for evaluation of theeffect of blood pressure and age in hypertensive group. We used materials of 70mm fluorography of 255 hypertensivemen above 150/90mmHg chosen from national police hospital during Jan. from Aug. 1981. Their age ranged from 20 to50 yeras. The results were as follows. 1. Cardiomegaly (above 50 percents in cardiothoracic ration) ofhypertensive men is 26%. 2. The cardiothoracic ration increased progressively with blood pressure and age, butpooly correlated between cardiothoracic ration and age than blood pressure. 3. The Lt. to Rt. cardiac diameterration gave similar trend to the cardiothoracic ration. It indicates that hypertensive cardiac enlargement mainlydepned on Lt. Ventricular enlargement. 4. The Lt. aortic knob width to thoracic diameter ration increasedprogressively with blood pressure and age, and had linear correlationship with blood pressure and age. Therefore,prominence of aortic knob is the most significant finding in hypertensive cardiovascular disease.
