The present study was made to investigate the difference of gastric motility between hypertonic and hypo- or atonic type of stomach in healthy adults. The subjects studied were 10 adults consisting of two groups of every 5 persons with hypertonic steer horn and hypo-or atonic long stomach respectively.<BR>Cinefluorogram of gastric motility of these subjects was taken on 16 mm cinefilm by means of an image intensifier. The size of longitudinal axis (L) and transverse diameter (T) of the gastric peristalsis was measured on each frame of the obtained film by a film motion analyzer.<BR>In the hypertonic steer horn type the reduction of L was greater than T, and the velocity of peristalsis was fast. On the contrary the reduction of T was greater than L and the velocity of the peristalsis was slow in the case of hypo- or atonic type of the stomach.<BR>The changes of the L and T seem to be related to the contractions of the longitudinal and circular muscle of the gastric wall respectively.<BR>Therefore, it is conceivable that participation of the longitudinal muscle to the gastric motility is greater than that of the circular muscle in the hypertonic type, while participation of the circular muscle is greater than that of the longitudinal muscle in the hypo- or atonic type.
