[A more efficient method of gastric intubation].

A self time-regulating aspiration device is presented. The device is a combination of a buffer container and a gastric tube and provides improved gastric intubation, gives more accurate results, has a high reliability of exploitation and there is no need of constant personal attendance.

[Comparative in vitro research on 2 new antacid combinations--Ulsan and Ulsan D].

Two new antacid combinations--Ulsan and Ulsan D with high acid-neutralizing properties, produced by original Bulgarian techniques are presented. They exceed in acid-binding and acid-reducing properties the drugs now in use: Antiacid, Neutracid, Almagel, Alcid V, Maaloxan, Gelusil-Lac.

[Method for determining the acid-reducing capacity of antacid preparations].

A method is proposed for the determination of acid-binding ability of antacids, enabling the automatic reading of pH changes. Changes are provided for work with original gastric juice. The method allows the determination of individual dosage of antacid for each patient.
