    Magnetic resonance imaging of cerebral infarction: Time course of Gd-DTPA enhancement and CT comparison (1988)
    Springer
    Neuroradiology 30 (1988), S. 372-378

    Notes: Summary Thirty-five patients (7 females and 28 males) with cerebral infarction and suspicion of cerebral infarction of 4 h to 27 months duration were studied 45 times with magnetic resonance (MR) imaging using Bd-DTPA. Spin echo (SE) images were obtained before and after the administration of Gd-DTPA (0.1 or 0.15 mmol/kg) and compared with the enhanced CT. MR imaging using Gd-DTPA was more sensitive than enhanced CT and very useful for detecting a new focus of cerebral infarction, especially in the cases with multiple infarcted areas and for showing the extent of cortical and subcortical infarction. In most cases the MR enhancement was obvious in the subacute stage, especially after cerebral embolism, and the signal intensity of the lesion tended to show a gradual increase. The diagnosis of embolism was accepted on the basis of acute onset without prior TIA, coupled with angiography showing the embolus itself and/or a capillary blush and a wide area of infarction.

    Radiation therapy of rat brain tumor using misonidazole as hypoxic cell sensitizer (1985)
    Springer
    Journal of cancer research and clinical oncology 109 (1985), S. 188-192 
    Details
    ISSN: 1432-1335
    Keywords: Experimental nervous system tumor ; Radiation therapy ; Misonidazole

    Topics: Medicine
    Notes: Summary Rat brain tumor was used as a model to evaluate radiation therapy with and without misonidazole. BD-IX rats were implanted intracerebrally with an ethylnitrosourea-induced glioma. Three series of experiments were performed, with radiation given 14 days after inoculation of the glioma clone. In each series, the following radiation doses were given: 500 rads once, 1,000 rads once; and 1,000 rads twice, every time with or without two different doses of misonidazole. Radiation therapy significantly prolonged survival when compared to the longevity of the control group. The dose of 1,000 rads given twice was highly effective and the life-span of tumor-bearing rats increased from 72% to 121%. Misonidazole plus irradiation negated the prolongation of survival, achieved with radiation therapy alone.

    Undifferentiated gliomas of the brain stem (1989)
    Springer
    Child's nervous system 5 (1989), S. 32-34 
    Details
    ISSN: 1433-0350
    Keywords: Undifferentiated brain-stem glioma ; Embryonal tumor ; Radiation therapy ; Intracranial biopsy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Undifferentiated gliomas of the brain stem were confirmed surgically in two young children. The patients were treated by aggressive irradiation of the entire neuraxis, similar to that administered for medulloblastoma. Therapy resulted in a good prognosis and there was no tumor recurrence.

    Online pH,pCO2 andpO2 monitoring system using two-way cyclic pumping of lactate Ringer as a baseline solution (1987)
    Springer
    Medical & biological engineering & computing 25 (1987), S. 45-50 
    Details
    ISSN: 1741-0444
    Keywords: Blood gas ; ISFET ; Lactate Ringer ; Patient monitoring ; pCO2 ; pH ; pO2

    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract A system for the online, simultaneous and intermittent analysis of blood pH, pCO2 pO2 using two-way cyclic pumping of lactate Ringer as a baseline solution is described. The multi-gas sensor is composed of a pH-ISFET with a temperature sensor, a pH-ISFET-based pCO2 sensor and a Clark-type pO2 sensor, bundled in an epoxy rod, and held in place in a flow cell which is directly connectable to an indwelling cannula. The system is controlled by a microcomputer, which supervises pump operation, temperature-compensation of sensor outputs, one-point calibration using sampled blood analysis, and provides graphical display of monitored results. Results of arterial blood-gas monitoring for mongrel dogs are presented which demonstrate the reliability of the present system over extended periods.
