The fiber projections from the dentate nucleus to the reticular formation of the brain stem in the rabbit
The projections from the dentate nucleus to the reticular formation of the brain stem in rabbit have been examined by means of the Fink-Heimer technique. The fibers arising from the dentate nucleus primarily p...

Acceleration of brain tubulin formation in the optic lobe of the chick embryo by light stimulation
The effect of light exposure on the protein patterns of optic lobe and forebrain of the chick embryo was analysed by a high-resolution micro-two-dimensional polyacryamide gel electrophoresis and computerized q...

Inhibitory actions of adenosine differ between ear and mesenteric arteries in the rabbit
In isolated ear and mesenteric arteries of rabbit, adenosine inhibited nerve-mediated contractions to a similar extent. However, the amplitude of the excitatory junction potentials evoked by perivascular nerve...

The morphology and distribution of photoreceptors in the retina of Bufo marinus
The number, cell morphology and retinal distribution of rods and cones were determined in the retina of the toad, Bufo marinus. Adult animals were sacrificed, both eyes were removed and prepared for either tangen...

Anoxic block of GABAergic IPSPs
In rat hippocampal slices GABAergic IPSPs are very rapidly suppressed by anoxia (in<2 min). Both early (GABAA) and late (GABAB) components are affected. After reoxygenation, the IPSPs recover, but only slowly and...

Distribution of glutamine-like immunoreactivity in the cerebellum of rat and baboon (Papio anubis) with reference to the issue of metabolic compartmentation
The cellular and subcellular localization of glutamine, a major glutamate precursor, was studied by means of an antiserum raised against glutaraldehydefixed glutamine. Ultrathin sections from the cerebellar co...

Potassium currents of rat basilar artery smooth muscle cells
Primary isolates of smooth muscle cells from the basilar artery of the rat were studied using whole-cell and single-channel patch-clamp techniques. Two distinct potassium currents were characterized. With low ...

Extracellular magnesium regulates intracellular free Mg2+ in vascular smooth muscle cells
Regulatory effects of extracellular magnesium ions ([Mg2+]o) on intracellular free ionized magnesium ([Mg2+]i) were exmained in cultured vascular smooth muscle cells (VSMCs) fromrat aorta by digital imaging micro...

Immunocytochemical staining with antibodies against protein kinase C and its isozymes in the turtle retina
An LM immunocytochemical study has investigated the patterns of staining in turtle retina with monoclonal antibodies to the α, β and γ isozymes of protein kinase C. The protein kinase C-γ antibody reveals cell...

Effect of peripheral nerve cut on neuropeptides in dorsal root ganglia and the spinal cord of monkey with special reference to galanin
Using the indirect immunofluorescence method andin situ hybridization, the localization and levels of immunoreactivities and mRNAs for several neuropeptides were studied in lumbar dorsal root ganglia and spinal c...

The ciliary ganglion of the cat: a light and electron microscopic study
The ciliary ganglia of eight healthy adult cats were studied by light and electron microscopy. The ganglion, measuring about 2 mm in length, was consistently found to be attached to the branch from the oculomo...

Whole-cell recording of the Ca2+-dependent slow afterhyperpolarization in hippocampal neurones: effects of internally applied anions
Using the whole-cell recording technique, we have examined the slow Ca2+-activated afterhyperpolarization (AHP) and its underlying current (I AHP) in hippocampal CA1 neurones of brain slices obtained from mature ...

Electrophysiological evidence for the presence of an apical H+-ATPase in Malpighian tubules of Formica polyctena: intracellular and luminal pH measurements
Cellular and luminal pH of isolated ant Malpighian tubules were measured in different bath K+ concentrations using double-barrelled pH microelectrodes. The electrochemical gradient for H+ across the basolateral a...

Prolonged inhibition of brain nitric oxide synthase by short-term systemic administration of nitro-l-arginine methyl ester
We studied the dose-response characteristics and the temporal profile of inhibition of brain nitric oxide (NO) synthase (NOS) elicited by i.v. administration of the NOS inhibitor nitro-l-arginine methyl ester (L-...

Increased locus coeruleus glutamate levels are associated with naloxone-precipitate withdrawal from butorphanol in the rat
Extracellular fluid levels of glutamate were measured in the locus coeruleus during butorphanol (a mixed agonist at μ-, δ-, and κ-opioid receptors) withdrawal by using microdialysis in conscious butorphanol-de...

Tenascin-C expression by neurons and glial cells in the rat spinal cord: Changes during postnatal development and after dorsal root or sciatic nerve injury
We have usedin situ hybridization with a digoxigenin-labelled probe for tenascin-C mRNA and immunocytochemistry with antibodies against tenascin-C, glial fibrillary acidic protein, OX-42 and the 200 kDa neurofila...

Regulation of FFA by the acyltransferase pathway in focal cerebral ischemia-reperfusion
Cerebral insult is associated with a rapid increase in free fatty acids (FFA) and arachidonic acid release has been linked to the increase in eicosanoid biosynthesis. In transient focal cerebral ischemia induc...
