Endoscopic sclerotherapy--personal experience.

Over the last 12 years, treatment of bleeding esophageal and gastric varices has improved considerably. By the use of new techniques and with increased experience the results of endoscopic sclerotherapy have been optimized. Acute variceal bleeding, esophageal or gastric, can now be reliably and definitively stopped using the tissue adhesive Histoacryl Blau.

Alzheimer's disease: a monoclonal antibody raised against paired helical filaments.

Paired helical filaments (PHF) were isolated from the cerebral cortex of patients with Alzheimer's disease (AD) by a combination of SDS treatment and density gradient centrifugation according to the method of Ihara et al. (1983). The protein component of the preparation was extracted with formic acid and Balb/c mice were used for immunization.

Experience with a transnasally fixed endoprosthesis for treating esophageal anastomotic leakage.

Eight patients suffering from leakage around the esophagus were treated with a transnasally fixed Celestin tube. All of the subjects had exhibited an anastomotic dehiscence after having undergone esophageal resection, cardia resection or total gastrectomy. Following treatment, in all cases the anastomoses healed quickly with no complications.

Maintenance of neuronal plasticity in the reticular core and changes in trophic activity in Alzheimer's disease.

1. Neuronal loss in Alzheimer's disease (AD) is accompanied by a proliferative response of the remaining neurons. 2.

A new technique for replacing an obstructed biliary endoprosthesis.

We report on a new method of stent exchange using a threaded device that enables removal of the clogged stent while simultaneously maintaining the original pathway without withdrawing the endoscope. With this method stent replacement has become more reliable, safer, simpler and quicker. This technique is also suitable for removal of stents dislodged inside the duct.

Endoscopic treatment of a pancreatic abscess originating from biliary pancreatitis.

We present a case report of a patient with two large pancreatic abscesses and an associated colonic fistula originating from acute gallstone pancreatitis, which we treated endoscopically. The common bile duct stones were extracted after a papillotomy. The abscess in the pancreatic head was drained into the duodenum and the one in the pancreatic tail irrigated through a nasopancreatic catheter using normal saline mixed with gentamycin.

[Method of transplantation of upper retained canines].

A holding device was introduced by mean teeth for transplantation can be fixed during all extraoral procedure.

[10 years' experience with endoscopic sclerotherapy of esophagogastric varices].

We report on our 10 years' experience in endoscopic sclerotherapy. A total of 1054 patients (90% of them with liver cirrhosis) were treated. During the first seven years (1978-1985) the hospital mortality of the bleeders was 31.

Transnasal fixation of the esophageal prosthesis.

We present a simple technique for the fixation of esophageal tubes. The endoprosthesis is anchored to a thin polyethylene catheter which is passed transnasally and attached to the ear. This method of treatment effectively prevents dislodgement.

Development of embryonic rat brain cells in aggregating cell cultures with special reference to cholinergic functions.

Mechanically dissociated cells from embryonic rat brain regions (telencephalon and metencephalon 15-16 days gestation) reassociate in a rotation culture to form aggregates. These reaggregate cultures show a variety of developmental phenomena, expression of specific cell types and the formation of synapses as the most prominent ultrastructural change. The biochemical maturation is evident in increasing specific activities of choline acetyltransferase (ChAT, EC 2.
