[A case of accessory middle cerebral artery associated with internal carotid artery aneurysm (author's transl)].

A case of accessory middle cerebral artery associated with internal carotid artery aneurysm was reported. A 50-year-old female was admitted to our hospital with complaints of headache, nausea, vomiting and conciousness disturbance. Lumbar puncture showed bloody CSF. Right carotid angiogram revealed saccular aneurysm of the internal carotid-posterior communicating artery and accessory middle cerebral artery originating from the horizontal portion of the right anterior cerebral artery. No other vascular lesion was observed on other angiograms. Operation was performed 2 days after admission. The neck of the aneurysm was clipped. Postoperative aseptic meningitis was cured by frequent lumbar punctures, and her course was uneventful. The etiological hypothesis of these cerebral vascular anomalies was briefly discussed.

Water soluble vitamins in patients with chronic renal failure and effect of B6 administration of immunological activity.

Blood concentrations of water soluble vitamins were studied in 29 undialyzed and 35 dialyzed patients with CRF, and 36 healthy volunteers. Effects of B6 administration on immunological parameters were studied in dialyzed patients. In dialyzed patients, whole blood B1 decreased, while plasma B2, B6 and serum B12 and folic acid increased. In undialyzed patients with uremia, plasma B2, serum B12 and folic acid increased, while plasma C decreased in patients with moderate CRF. Oral administration of B6 for 4 wks was associated with improved tuberculin skin tests and PHA mitogen responses in dialyzed patients. Supplementation of B1 is required for patients with CRF while B6 and C may be considered.

[Changes in the response to drugs of the rat stomach after a chronic vagotomy and a sympathectomy (author's transl)].

Effects of cholinergic agonists and serotonin were examined on the chronically denervated stomach fundus. We developed a new method of adrenergic denervation (sympathectomy), which was confirmed chemically, histochemically and functionally. Vagotomy was performed by the usual method. The sensitivity of the longitudinal muscle of the fundus to cholinergic agonists and serotonin was not modified by chronic sympathectomy or vagotomy when determined from the ED50 of the dose-response curve. The maximum contractile response of vagotomized fundus to each cholinergic agonist and to serotonin was significantly decreased, whereas only a slight decrease was observed in sympathectomized fundus. Ca2+-contracture in Ca2+-free isotonic K+ Ringer's solution was markedly decreased in chronically vagotomized or sympathectomized fundus. Efflux of 45Ca in Ca2+-free isotonic K+ Ringer's solution was significantly lowered by vagotomy but only slightly by sympathectomy. No significant change in ATP content was observed in the vagotomized or sympathectomized fundus.
