    Notes: Summary A necropsy case of a primary rhabdomyosarcoma with chronic paragonimiasis in the cerebrum of a 68-year-old man is reported. The clinical data showed a right hemiplegia and dysarthria which became lethal in 6 months even though operation and radiation therapy were performed. Computed tomography revealed a large low-density area associated with the peripheral enhancement in the left basal ganglia, and multiple conglomerated calcified masses in the left temporal and occipital lobes. Biopsied and necropsied materials of the tumor in the basal ganglia was reddish brown in color and histologically was composed of purely mesenchymal derivatives with both embryonal and mature striated muscle cells but neither neuronal nor glial elements. Some of the tumor cells with extending slender cytoplasms showed obvious cross striations at the light and electron microscope levels and immunohistochemical reactivity for myoglobin. All tumor cells were also positive for vimentin, but not for glial fibrillary acidic protein. The clinical and necropsy findings revealed no primary lesion anywhere but in the brain. In addition, numerous dead oval eggs ofParagonimus westermani were found in many cystoid lesions encapsulated by thick connective tissues with calcification and/or ossification. Clinicopathological features of 24 cases of primary rhabdomyosarcoma of the central nervous system reported in the literature are reviewed briefly. The histogenesis of this tumor are discussed together with comments on cerebral paragonimiasis.

    Notes: Abstract An ultrasonic flowmeter incorporated with implantable miniature sensors was developed. Two sets of miniature ultrasonic sensors are attached to the surface of a blood vessel. The outer diameter of the vessel and the blood velocity are measured simultaneously by means of the ultrasonic transit-time technique and the ultrasonic Doppler method, respectively. Instantaneous blood flow is calculated by multiplying the flow velocity by the cross-sectional area calculated from the diameter Stroke volume and cardiac output can also be obtained, when the system is applied to the ascending aorta. After preliminary benchtop tests, acutein vivo studies were carried out to evaluate the accuracy and performance of the system. The blood flow in the descending aortas of dogs and a goat were measured simultaneously by the ultrasonic system and an electromagnetic flowmeter. The correlation coefficient between the data obtained by the two methods was 0·968. The system was applied to measure the blood flow in the ascending aortas of goats which had had heart failures induced and were implanted with left ventricular assist devices.
