[Microtumor presenting with temporal lobe epilepsy--a case report].

A 15-year-old girl was admitted to our clinic on July 16, 1985 with the epilepsy which had been resistant to various anticonvulsant therapies. At the age of 10 years automatism seizure, characterized by purposeless movement of arms and head of which the patient was unaware, began to occur and became as frequent as two to three times each day. From the age of 13 years, there were also grand mal seizures several times a year in spite of medical treatment. She had normal delivery and no history of febrile convulsion. There was no family history of epilepsy or mental disease. When examined on admission, she had normal personality and intelligence. There was no neurological abnormality. She complained of sleepiness and hirsutiness. Fit of automatism occurred two to three times a day during admission, though the blood levels of anticonvulsant drugs such as phenobarbital, phenytoin and carbamazepine reached to therapeutic concentration. EEG examination including infratemporal lead recording showed right temporal spike focus. But all the neuroradiological studies such as skull X-rays, CT, cerebral angiography and magnetic resonance imaging failed to show abnormal finding. Right temporal lobectomy was carried out under general anesthesia on Aug 22, 1985, and anterior two-thirds of the middle and the inferior temporal gyri were resected deeply to anterior hippocampus. To the naked eye, no abnormal finding was noted during the operation. In the surgical specimen, macroscopically nothing abnormal was found. Microscopically, serial sections of the lobe revealed clusters of oligodendroglial cells in cortical to subcortical region of the medial basal part of the temporal lobe.(ABSTRACT TRUNCATED AT 250 WORDS)

Neutralizing monoclonal antibodies against recombinant human interleukin-2.

A series of hybridoma cell lines which produce monoclonal antibodies (MAbs) against recombinant human interleukin-2 (rIL-2) have been established by fusion of murine myeloma cell line P3-NS1-1-AG4-1 and spleen cells of BALB/c mice which had been immunized with rIL-2. 48 hybridoma strains were selected by a solid-phase screening method which produced MAbs reacting with IL-2: four MAbs, L-15, L-20, L-34, and L-61, exhibited strong inhibition of the proliferating effect of rIL-2 on IL-2-dependent cell lines, NK7 and CTLL-2. L-61, the most potent MAb among them, also neutralized natural human IL-2, while the other three MAbs were unreactive. All the four MAbs were specific to human IL-2: they did not cross-react with mouse or rat IL-2. These MAbs are expected to be useful tools in the investigation of IL-2 function.

Radionuclide cardiac monitoring system using dual cadmium telluride (CdTe) detectors: specification and some clinical applications.

The construction, physical characteristics, software and some clinical applications of a computerized dual cadmium telluride (CdTe) detectors system for continuous cardiac monitoring are described. The detectors and collimators are small, light and convenient for attachment to the chest wall. Data can be collected at 0.05 s intervals and for up to 3 h. Clinical studies in 33 patients using a prototype system demonstrated reasonably good correlation with left ventricular ejection fractions determined by a scintillation camera-computer system (r = 0.928). The application of this system to continuous monitoring of left ventricular function during exercise or drug stimulations has been found to be clinically useful.

Effects of kanamycin sulfate on cochlear potentials and potassium ion permeability through the cochlear partitions.

The cochlear microphonics (CM), endocochlear potential (EP) and potassium ion activities in the endolymph and perilymph were measured in guinea pigs which received daily successive intramuscular injections of 500 mg/kg of body weight of kanamycin sulfate. Preyer's reflex threshold at 8 kHz began to increase after the 5th day of kanamycin treatment and disappeared on the 11th day. The maximum output of CM at 8 kHz began to decrease with a time course similar to Preyer's reflex. The potassium ion activities in the endolymph and perilymph and the EP did not change appreciably through all experimental days. The magnitude of the negative EP decreased in parallel with the reduction in CM and the relative potassium conductance (GK) between the endolymph and perilymph. These results lend support to the hypothesis that the site of production of the negative EP is probably in the hair cells and that the negative EP is mainly dependent on the permeability of the potassium ions in the organ of Corti.

Mass stranding of Odontoceti caused by parasitogenic eighth cranial neuropathy.

Hearing organs of the Odontoceti from two mass strandings in 1983 and 1986 were examined histopathologically. In the 1983 stranding, two of three pilot whales (Globicephala macrorhynchus) were necropsied and numerous Nasitrema sp. were found close to the eighth cranial nerve (nervus vistibulo cochlearis) in both animals. Patchy degeneration of the eighth cranial nerve in and out of the modiolus of the cochlea was observed. In the 1986 stranding, five of 125 false killer whales (Pseudorca crassiclens) were examined and numerous trematodes (Nasitrema gondo) were found in the tympanic cavities. Severe degeneration of the eighth cranial nerve was discovered and there were many trematode eggs in the nervous and surrounding tissues. Parasitogenic eighth neuropathy is proposed again as the cause of mass stranding of the Odontoceti.

[Unruptured intracranial aneurysms associated with vascular disorder of the vertebro-basilar system: report of five cases].

Among fifty-two angiographically examined patients of vertebro-basilar disorder, incidental intracranial aneurysms were found in five cases. These were four males and a female, ages ranging from 42-67 year old. Vertebro-basilar disorders were ischemic origin in three cases and hemorrhage in two cases. Locations of incidental aneurysms were the internal carotid artery, middle cerebral artery, anterior communicating artery and basilar artery. They were multiple in three cases. They were operated on radically, except one case whose status seemed to be untolerable to the operation. Intervals between strokes and operations were 51-81 days. In spite of successful operation, mild to moderate disturbances of consciousness appeared in three cases. In two cases they were subsided in a week, but in one case it persisted for two months. Fortunately, final results in all operative cases were good. These transient deterioration of consciousness level might probably be ascribed to vertebro-basilar insufficiency once subsided but resumed due to the operative affections. Through a small experience of four cases, three points would be discussed to prevent such hazards. 1) Extreme systemic hypotension as well as hypertension should be avoided during operation. 2) GOF might be an anesthesia of choice in such cases. 3) Operation should be favorably waited for more than six months after the ictus.

[Gliosarcoma--a case report].

UNLABELLED: A 60-year-old woman was admitted to our clinic on September 29, 1983 because of a five months history of personality change and progressive left sided motor weakness. Neurological examination on admission revealed left hemiparesis and papilledema. She was severely demented. Skull X-rays were normal. CT scan showed a large right parietoccipital mass which was markedly enhanced by contrast medium. Right internal carotid angiogram showed abnormal vascular shadow, early draining veins and tumor stain in parietoccipital region. Right external carotid angiogram showed that the tumor was partly fed by the middle meningeal artery in "sunburst" pattern. The tumor was resected subtotally through right parietoccipital craniotomy on October 4, 1983. At operation, well demarcated, reddish-grey tumor attached to the dura was found. Several branches of the middle meningeal artery were penetrated into the tumor through the attachment. The tumor grossly appeared to be a meningioma in its superficial part, but demarcation was found being obscured in removing the deeper part of the tumor. PATHOLOGICAL FINDINGS: The specimens obtained from the superficial part of the tumor showed admixture of two distinctive neoplastic tissues. One was malignant mesenchymal features. Fibrosarcomatous nature was obvious, characterized by cells with moderately chromatic, fusiform nuclei arranged in parallel rows and eosinophilic fibers deeply stained in silver preparation for reticulin. The other was gliomatous tissue forming islands surrounded by the sarcomatous tissues. Both tissues were histologically malignant, as evidenced by mitotic figure, high cellularity, atypical features and variability. In deeper part, sarcomatous findings was less noticed and features of glioblastoma multiforme more prominent, characterized by marked astrocytic anaplasia, endothelial proliferation and extensive perinecrotic pseudopalisading.(ABSTRACT TRUNCATED AT 250 WORDS)

[A population survey on mass screening program for gastric cancer. Part 2. Why don't they receive mass screening examination?].

The attitude of non-examined residents to a mass screening program for gastric cancer has been surveyed by a self-administered questionnaire among 3660 residents in a small town near Kitakyushu City. Among 1159 subjects who had not received any type of examination during the past 3 years, the answers of 638 subjects who completed the questionnaire were analyzed in this study. Reasons for not being examined were classified into 4 types; "unnecessary", "rejected", "inconvenient" and "others". The most frequent reason for not taking part in the screening program was "inconvenient" which means that there were some difficulties for them to participate in the program even if they wanted to. This reason was followed by "unnecessary" and "rejected". "Inconvenient" was the main reason for not being examined among people in their forties and fifties and/or among those who have jobs. Among elderly people, "unnecessary" had the highest frequency. "Rejected" was the least important reason in all age groups. In each age group "rejected" was found more frequently among females than males. As the type of reason for not being examined was different among groups, it is essential to work out different countermeasures for each group in order to raise the participating rate.

[A population survey on a mass screening program for gastric cancer. 1. Population characteristics related to examination rates for the screening program].

The types of examination received for gastric cancer during the past 3 years have been surveyed by a self-administered questionnaire among residents of a small town near Kitakyushu City. Among 3660 surveyed, 2205 subjects who completed the questionnaire are analyzed in this study. Examination rates of mass screening for males were higher than those for females. Males in their forties and fifties and females in their forties through sixties have higher examination rates than other age groups. Higher examination rates were seen in public officials and employees who have opportunities to receive the screening program at work site. On the other hand, among people without a job and housewives who have opportunities to receive a screening program offered only by the town hall, examination rates of the mass screening program were low. More people with a family history of cancer death were examined than those without a similar family history. There was no difference in the examination rates by the mass screening program between the people who took care of their health and those who did not. In order to raise examination rates for the mass screening program, it is essential to improve the systems of this program which can be easily accepted, and to educate residents in order to stimulate motivation for screening.
