We examined the retinal ganglion cell layer of the dromedary camel, Camelus dromedarius. We have estimated that there are 8 million neurons in the ganglion cell layer of this large retina (mean area of 2,300 mm(-2)). However, only approximately 1 million are considered to be ganglion cells. The ganglion cells are arranged as two areas of high cell density,(More)
The ability of bone to resist catastrophic failure is critically dependent upon the material properties of bone matrix, a composite of hydroxyapatite, collagen type I, and noncollagenous proteins. These properties include elastic modulus, hardness, and fracture toughness. Like other aspects of bone quality, matrix material properties are(More)
It has been suggested that elevated cytosolic free calcium plays a key role in acetaminophen-induced cell death. The present study has examined the effect of a toxic concentration of acetaminophen on cytosolic free calcium in single mouse hepatocytes, using the dye fura-2 and video imaging fluorescence microscopy. Cytosolic free calcium was calculated from(More)
Most species of eutherian (placental) mammals examined have two types of horizontal cell, one is axonless and the other has a short axon. We have recently shown that a marsupial, the quokka wallaby, also has two types of horizontal cell and that the axonless cell in this species has unusual stubby processes that pass through the inner nuclear layer to reach(More)
Antipyrine elimination kinetics were measured in psychotic patients receiving either long-term chlorpromazine or fluphenazine decanoate therapy and in non-medicated control subjects. Patients receiving chlorpromazine metabolised antipyrine faster than the controls while, in patients receiving fluphenazine decanoate, there was not change. The results suggest(More)
Quantitation of hepatic microsomal enzyme induction in epilepsy has a theoretical role in identifying patients at risk of metabolic bone disease, in assessing drug compliance and in predicting anticonvulsant dose/serum level relationships. The clinical usefulness of antipyrine half-life as a measure of enzyme induction in chronic epilepsy has been explored(More)
