    Notizen: Summary In order to investigate the pathogenesis of periventricular lucency (PVL) in hydrocephalus, CT scans were performed with monitoring of the epidural pressure in a series of dogs with hydrocephalus induced with kaolin. PVL of various degrees was detected in the experimental animals, which disappeared immediately after a shunting operation. Correlations have been attempted between PVL on CT scans and histological examinations, contrast enhancement studies, metrizamide ventriculography, and measurement of regional cerebral blood flow in the periventricular white matter. PVL in hydrocephalus is considered to represent acute edema or chronic CSF retention in the periventricular white matter caused by an increase of water content. In other words, it is regarded as a sign of existing or preceding intraventricular hypertension on CT scan, and seems to be a reversible phenomenon to some extent. PVL may therefore became an indication for a shunt.

    Southern pine beetle: Olfactory receptor and behavior discrimination of enantiomers of the attractant pheromone frontalin (1982)
    Springer
    Journal of chemical ecology 8 (1982), S. 873-881

    Notizen: Abstract In laboratory and field bioassays, the response ofDendroctonus frontalis was significantly greater to the mixture of (1S, 5R)-(−)-frontalin andalpha-pinene than to (1R,5S)-(+)-frontalin andalpfa-pinene. Electro-physiological studies revealed that antennal olfactory receptor cells were significantly more responsive to (1S, 5R)-(−)-frontalin than to (1R, 5S)-(+)-frontalin. Both enantiomers stimulated the same olfactory cells which suggests that each cell possesses at least two types of enantiomer-specific acceptors.
