    Notes: Abstract Small subcortical infarctions resulting from large-vessel disease are often observed. It is important to distinguish these from pure lacunar infarction resulting from small-vessel disease because the investigations and examinations differ. We investigated the differences on brain magnetic resonance imaging (MRI) between small subcortical ¶“lacunar-like” infarcts resulting from large-vessel disease and pure lacunar infarcts. Thirteen subjects with small lacunar-like infarcts (size 〈 2 cm), resulting from large-vessel disease, ¶and 30 subjects with lacunar infarcts (〈 2 cm), without large-vessel disease were studied. We measured infarction size using a 1.5-T MRI device and evaluated silent subcortical hyperintensity lesions using the modified Scheltens’ score. Large-vessel lesion was confirmed by conventional angiography, duplex carotid scan, and magnetic resonance angiography. There was no difference in the mean age of the two groups. Cerebrovascular risk factors and atherosclerotic complications were also comparable for the two groups. Progressive stroke was more common ¶in the lacunar-like infarction group than in the lacunar infarction group ¶(P = 0.004). Scores for periventricular hyperintensity, white matter hyperintensity, basal ganglia hyperintensity, and total subcortical hyperintensity scores were significantly higher in the lacunar infarction group than in the lacunar-like infarction group. The difference in basal ganglia hyperintensity scores was remarkable (P = 0.001). The enlargement of the perivascular space was also significantly greater in the lacunar infarction group than in the lacunar-like infarction group. These findings seem to reflect differences in the pathogenesis of infarction between the two groups. Silent subcortical hyperintensity lesions and enlargement of perivascular space are useful for between distinguishing small lacunar-like infarct resulting from large-vessel disease and pure lacunar infarction. This may have significant implications for the management of patients with lacunar-sized infarctions. It suggests that the pathogenesis of lacunar-sized infarction is variable.

    Notes: An electron tracing code in spherical coordinates was used to treat irregular, nonspherical boundaries in the "Herzog regions" at the exit and entrance planes of hemispherical energy analyzers. Some of the classical designs, i.e., the sudden cutoff "ideal field" approximation, real apertures in the 180° plane, the Herzog correction, the Jost correction, and shortened spheres were compared and checked for improvements. Ratios of gap to average radius from 0.2 to 0.55 are covered. Focusing, maximum trace width, base resolution, and the banana-shaped asymmetries from the circular reference path are investigated. Nearly ideal focusing and beam width can be restored in all devices by simply rotating the entrance beams through a small negative angle. Design equations are provided. © 2000 American Institute of Physics.

    Notes: Hatchery-reared juvenile black sea bream Acanthopagrus schlegeli (Bleeker) are characterized by high lipid storage and low levels of highly unsaturated fatty acids in their bodies. In the present study, we assessed the effects of dietary fortification of the diet with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the improvement of physiological activity. Black sea bream 50 days old with an average weight of 0.02 g were reared for 50 days on either a control diet (commercial diet) or a commercial diet fortified with 3% EPA and DHA. The fortification with EPA and DHA reduced lipid storage in adipocytes in the intraperitoneal cavity, but decreased muscle lipid level. Consequently, the total lipid level decreased in the bodies of the fish. The proportions of EPA and DHA in muscle, liver and adipocytes were markedly increased by diet fortification, and the EPA and DHA proportions did not differ from those of wild fish. The cell diameter of adipocytes was reduced by EPA and DHA fortification. Liver function and resistance to air-dipping were improved by fortification. The results of a starvation test revealed the efficient mobilization of lipid reserves in response to energy demands prior to protein exhaustion in the EPA/DHA-enriched group. The results implied that increasing the incorporation of dietary EPA and/or DHA should be considered in the larval stage of black sea bream culture.

    N-Methylation ability for azaheterocyclic amines is higher in Parkinson's disease: nicotinamide loading test (2000)

    Notes: Summary. The discovery of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) leads to the hypothesis that Parkinson's disease (PD) is may be initiated or precipitated by endogenous toxins by the mechanism similar to that of MPTP in genetically-predisposed individuals. The higher cerebrospinal fluid levels of N-methylated azaheterocyclic amines, such as β-carboline and tetrahydroisoquinoline, have been found in parkinsonian patients compared with age-matched controls. To estimate the N-methylation ability for azaheterocyclic amines in parkinsonian patient, nicotinamide was dosed with 100 mg to 26 parkinsonians and 20 controls consisted of 16 other neurogenic disease patients and 4 healthy volunteers. The urine was collected for 4 h, and then analyzed urinary its metabolites by an improved HPLC method. Nicotinamide has a pyridine ring in its structure and may be metabolized through the pathways similar to those for the endogenous neurotoxins. The urinary excretions of nicotinamide metabolites were significantly affected by aging. The excretion of N1-methylnicotinamide decreased along with aging both in PD patients and controls. In younger (65 years old or younger) PD patients, the excretion amount of N1-methylnicotinamide was significantly higher than that in younger controls. The decline rate of N1-methylnicotinamide excretion in parkinsonians was significantly greater than that in controls; the rate is more than 2-fold higher in parkinsonian patients. The age-associated de-crease in 1-methyl-2-pyridone-5-carboxyamide excretion was observed only in parkinsonian patients, but not in controls. The total excreted amount of N-methylated metabolites (N1-methylnicotinamide plus 1-methyl-2-pyridone-5-carboxyamide) was also observed the age-related decline in both groups. The urinary excretions of nicotinamide and nicotinamide-N-oxide were not influenced by aging. These results would indicate that the excess N-methylation ability for azaheterocyclic amines before the onset had been implicated in PD. On the other hand, the present results suggested that the contribution of aberrant cytochrome P450 or aldehyde oxidase activity acting on the pyridine ring, that could act as detoxification routes of endogenous neurotoxins, would be small in the etiology of PD.

    Notes: Abstract  We report an osteoblastoma-like osteosarcoma in the right proximal fibula in a 22-year-old woman. Radiographs showed an irregular osteolytic lesion from the metaphysis to the epiphysis in the proximal fibula with partial destruction of cortical bone. Tissue from a biopsy indicated a typical osteoblastoma. Curettage and bone graft was performed. One year after the surgery, local recurrence occurred, and a wide excision was performed. Histological examination of the en-bloc surgical specimen revealed the tumor had permeated through the host bony trabeculae, although the nuclear atypia was not marked. Immunohistochemical expression of MIB-1 was detected in 9.0% of cells.

    Notes: Abstract  We report the case of a 43-year-old man who presented with an osteolytic and expansive lesion in the left distal femur mimicking a giant cell tumor. Magnetic resonance imaging (MRI) showed that most of the lesion was cystic, and histological examination revealed fibrous dysplasia with marked cystic degeneration. Radiographic findings of cystic fibrous dysplasia in the end of a long bone may be similar to those of a giant cell tumor, and a biopsy is essential for the final diagnosis.

    Notes: Abstract  We describe a patient who experienced a recurrence of idiopathic iridocyclitis on day 12 after autologous peripheral blood stem-cell transplantation (auto-PBSCT) followed by G-CSF administration for acute lymphoblastic leukemia (ALL). Autologous SCT has been reported to be effective and safe in achieving dose intensification of chemotherapeutic drugs for the treatment of hematopoietic malignancies, but its therapeutic effect on autoimmune diseases is not definite. The findings from the present case suggest that auto-PBSCT followed by G-CSF administration for patients with a history of some kind of autoimmune disorders may induce exacerbation or recurrence of its symptoms after hematopoietic recovery.
