Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

In attempt to investigate histone fractions and non-histones of parasites, nuclei were isolated from Fasciola hepatica by the procedure of Pogo et al. (1966). Histone fractions H1, H2a, H2b, H3 and H4 were prepared from isolated nuclei by the procedure of Johns (1964 and l967). The five histone fractions found in most tissues were also present in the Fasciola hepatica histones. These histone fractions were characterized by amino acid analysis and by polyacrylamide disc gel electrophoresis. Non-histone proteins were extracted from isolated Fasciola hepatica nuclei and separated by SDS-polyacrylamide gel electrophoresis. The results of the experiment were summarized as follows: The yield of whole histone recovered was 2.47 mg per 1 g of Fasciola hepatica. The yield of DNA was 1.02 mg per gm of tissues. Consequently the DNA to histone ratio was 1:2.44. The relative amounts of five fractions, i.e., Hl, H2a, H2b, H3 and H4 were 19.96 percent, 26.48 percent, 29.60 percent, 12.56 percent and 14.37 percent, respectively. Amino acid analysis of the individual histone fractions showed that the over-all compositions were similar but not identical to those of corresponding fraction from calf thymus. It was found that histone H2b fraction of Fasciola hepatica contained detectable amounts of epsilon-N-monomethyllysine. No evidence for the presence of methylated lysine or other side-chain derivatives was reported on this histone fraction. In SDS-polyacrylamide disc gel, it showed that 17 protein bands of nuclear acidic protein can be identified visually.

BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

PURPOSE: The Singh index which is based on a plain radiograph has commonly used in assessing the grade of osteoporosis. We studied value of the Singh index in assessing the grade of osteoporosis by obtaining reliability of the Singh index and correlation between the Singh index and bone mineral density. MATERIALS AND METHODS: Six observers assessed radiographs of 60 patients suspected osteoporosis. The interobserver and intraobserver agreement of the Singh index were obtained by using kappa statistics. The bone mineral density of proximal femur was measured by dual energy X-ray absorptiometry in all patients, and then the results of bone mineral density were compared with those of Singh index by using percentage of variance. RESULTS: The kappa values of interobserver agreement ranged from 0.28 to 0.76 (mean value: 0.45) and the strength of the agreement was moderate. The percentage of variance of BMD which was explained by Singh index was 7.1%. CONCLUSIONS: The results of this study suggest that the Singh index has low clinical value in assessing the grade of osteoporosis
