Calcification is exceedingly rare in schwannomas. In the literatures, we found only three reports of schwannomas with calcification. We report two cases of intracranial calcified schwannomas, one in the anterior cranial fossa and the other in the middle cranial fossa.

The present study was undertaken to determine the pattern of infestation with the encysted larvae of digenetic trematodes in freshwater fish collected in both the natural and fish breeding ponds in Kyungpook Province, Korea. The fish collected in the two natural ponds, Nass-chil, and Sa-il, and three fish breeding ponds, Deok-dong, Mo-gok, and Seongryu-tunnel, were examined from July 1980 to August 1981. The data were compared with the results obtained from freshwater fish caught in the river Kumho by Hwang and Choi(1980). Ten species of fish caught in the ponds were examined for the presence of the larval trematodes. Seven species of the larvae, Clonorchis sinensis, Cyathocotyle orientalis, Echinochasmus species, Exorchis oviformis, Metacercaria hasegawai, Metagonimus yokogawai, and Metorchis orientails and two kinds of undetermined cyst A and B were found. The infestitation rate for Clonorchis sinensis metacercaria in the Korean shiner, Gnathopogon atromaculatus collected in the natural ponds was higher than the rate in the river Kumho by Hwang and Choi(1980), but lower in the fish collected in the breeding ponds. By contrast, the infestation rate in the flat bitterling, Paracheilognathus rhombea in ponds was higher, while there was no change of the rate in the southern top-mouthed minnow, Pseudorasbora parva. The intensity of infestation, expressed as the average number of Clonorchis sinensis metacercaria per gram of flesh, were lower than in the bullhead, Coreobagrus brevicorpus, and Gnathopogon atromaculatus in the ponds in 1981. The intensity was higher in Paracheilognathus rhombea, but no fluctuation in the intensity of infestation in Pseudorasbora parva was observed. The infestation rates and densities for the encysted larvae of digenetic trematodes except for Clonorchis sinensis varied from fish to fish. However, it was found that the rate and intensity of the larval trematodes from all the fish in the ponds was lower than from those in the rivers in Kyungpook Province, Korea.

The significance of measurement of the spinal canal size was well recognized in case of detection of intraspinal tumor as well as diagnosis of spinal stenosis. The measurement of sagittal diameter of the lumber spinal canal by plain x-ray film is not always easy. However, the new method designed by Eisenstein made the measurement of sagittal diameter of the lumber spinal canal by plain x-ray film very easy. In order to study the range of normal values of the sagittal diameter of lumber spinal canal in Korean adults, authors measured antero-posterior and transverse diameter of the lumbar spinal canal in 290 normal Korean adults by Eisensteins method. The results obtained are as follows: 1. Mean values of sagittal diameter of the normal Korean adults male was 17.37±1.05mm at Ll, 16.43±1.12mm at L2, 15.89±1.20mm at L3, 15.45±1.24mm at L4, and 17.34±1.13mm at L5 vertebra and in female, 17.41±1.23mm at Ll, 16.45±1.20mm at L2, 16.14±1.41mm at L3, 15.40±1.32mm at L4, and 17.25±1.20mm at L5 vertebra. 2. Mean values of transverse diameter of the normal Korean adults male was 23.54±1.18mm at Ll, 24.61±1.17mm at L2, 25.78±1.41mm at L3, 27.72±1.86mm at L4, and 30.42±2.23mm at L5 vertebra and in female, 23.06±1.45mm at Ll, 23.90±1.48mm at L2, 25.21±1.53mm at L3, 26.62±1.88mm at L4, and 29.70±2.41mm at L5 vertebra. 3. In transverse diameter, it was increased more and more to the lower lumber level, the widest at L5 vertebra. 4. In sagittal diameter, it was decreased less and less to the lower lumbar level, the narrowest at L4, and increased again at L5 vertebra. 5. The difference of sagittal and transverse diameter of lumbar spinal canal at each level of lumbar spine was very significant statistically. 6. The difference of the transverse diameter of the lumber spinal canal between male and female was significant statistically but that of the sagittal diameter was not. 7. The difference of the sagittal and transverse diameter between each age group was not significant statistically.

Many types of osteotomy have been proposed for the treatment of cubitus varus deformity of the elbow, and various methods for fixation of the osteotomy site have also been described. However, no method has been perfect. We treated two cases of cubitus varus elbow deformity with step-cut osteotomy using a new fixation method with two crossing screws and an anatomically designed locking plate. Active assisted elbow range of motion (ROM) exercise was permitted at postoperative 3 days, after removal of the drainage. Preoperative and postoperative humerus-elbow-wrist angles and ranges of motion of the two patients were compared. At 3 months follow-up, each patient had recovered the preoperative elbow ROM, and achieved the complete bony union of the osteotomy site and proper correction of the cubitus varus deformity. In addition, the appropriate remodeling of the lateral bony protrusion was observed. Therefore, we introduce a new fixation method for achievement of stable fixation allowing immediate postoperative elbow motion after corrective osteotomy for cubitus varus deformity in young adults.
