Radioimmunoassay for colchicine: synthesis and properties of three haptens

For the development of radioimmunoassay procedures for colchicine, three haptens, N-ethylamino-colchiceinamide, 4-formylchochicine - (O-carboxymethyl) oxime and 4-hydroxymethylcolchicine O-hemisuccinic acid were synthetized and characterized by mass and proton magnetic resonance spectrometries. The conjugates obtained by coupling the haptens to bovine serum albumin were employed to immunize rabbits and goats.

[Functional results of 280 Pean type gastrectomies for chronic Cruveilhier ulcer]

The authors review 216 gastrectomies of Péan type for gastric or duodenal ulcer with a follow up of between one and 12 years. In 91 patients, the follow up was more than five years. Six criteria were adopted for the essessment of the functional results: increase in body weight which may be of several types, the diet, post-prandial symptoms, return to work, asthenia recurrent ulcer. Each of these criteria were studied separately in all operated patients and analysed in relation to the follow up period. Except for recurrent ulcer, with occurred in 2% of cases, the results obtained improved with time. A routine study such as Visick's method completes this presentation. The good and very good results were 81% at 5 years, average results were 16% and poor results 3%. The differences between gastric and duodenal ulcer were negligeable. After comparison with the data in the literature, this level study seemed more interesting than a statistical study.
