[Management of ruptured aneurysm of anterior communicating artery by emergency operation].

Objective: To investigate the effectiveness of emergency operation on ruptured anterior communicating artery.

Methods: Twenty-one cases of ruptured anterior communicating aneurysms, 9 of grade III, 10 of grade IV and 2 grade V according to Hunt-Hess classification, were treated by emergency clipping.

Results: By the time of being discharged from hospital, 16 patients were perfectly recovered, 2 suffered from moderated disability, 1 suffered from severe disability and 2 were dead.

Chemical coding and electrophysiology of enteric neurons expressing neurofilament 145 in guinea pig gastrointestinal tract.

Electrophysiologic recording and indirect immunofluorescence were combined to study localization of the medium-sized neurofilament 145 (NF145) component of the cytoskeleton in morphologically identified neurons in the myenteric and submucosal plexuses of the guinea pig enteric nervous system. Neuronal localization of chemical markers, including calbindin DK28, calretinin, nitric oxide synthase, choline-acetyltransferase, neuropeptide Y, serotonin, neurokinin 1 receptor protein, and somatostatin, was integrated with electrophysiologic and morphologic results for a more complete assessment. NF145 immunoreactivity (-IR) was present in ganglion cells with Dogiel type I morphology in the myenteric plexus of the stomach and small and large intestine.
