ABSTRACT
A 14-year-old boy and a 11-year-old boy presented with subdural hematomas as complications of preexisting arachnoid cysts in the middle cranial fossa, manifesting as symptoms of raised intracranial pressure. Both had a history of heading the ball in a soccer game about 7 weeks and 2 days before the symptom occurred. There was no other head trauma, so these cases could be described as "heading injury." Arachnoid cysts in the middle cranial fossa are often associated with subdural hematomas. We emphasize that mild trauma such as heading of the ball in a soccer game may cause subdural hematomas in patients with arachnoid cysts.

During a virus survey carried out in the period 1989-90 with 148 fecal samples collected from cats in Japan, three reovirus strains were isolated in feline cell cultures. Two strains (Nos. 114 and 140) were from 48 diarrheal fecal samples and another strain (No. 32/41) was from 100 normal fecal samples. The strains grew in feline and simian cell cultures with producing typical intracytoplasmic inclusion bodies in which virus particles were densely packed. All strains, especially Nos. 32/41 and 140 strains, showed trypsin-dependent growth in vitro. Their ultrastructural and genomic properties were characteristic of genus reovirus in the Reoviridae. All strains agglutinated erythrocytes of human type O but not of bovine. Although they were identified as serotype 2 by hemagglutination-inhibition test with the hyperimmune sera against human reovirus prototype strains, No. 114 strain was typical and the other two strains were atypical serotype 2 reoviruses. Furthermore, from the reason that Nos. 32/41 and 140 strains possessed some common properties though derived from cats in distant locations, they were considered to be reoviruses having been maintained in the cat population. Seroepizootiologic survey revealed that the prevalence of serotype 3 infection was most widespread and serotype 2 was least among three serotypes of reovirus in a cat population.

Organic acids in rabbit renal tissue biopsy were analyzed by capillary column gas chromatography--mas s spectrometry. The change of these organic acids under ischemic conditions was determined over 60 min after clamping the renal artery and vein. The results showed that lactic acid, glycolic acid, 2-hydroxybutyric acid, 3-hydroxypropionic acid, 2-methyl-glyceric acid, glyceric acid and malic acid increased at 4 and 6 min after clamping, but then decreased at 15 min. Glycerol increased 2 min after clamping and then decreased. However, 3-deoxyaldonic acids of 3-deoxytetronic acid, 3-deoxy-2-C-hydroxymethyltetronic acid and 3-deoxypentonic acid decreased in the renal tissue biopsy from 2 min after clamping.
