[Gastric motor activity in Varanus griseus lizards].
Motor activity of the stomach in V. griseus consists of contractions which follow the rhythm of 7-10 movements per 15 min. In contrast to tortoises, no periodic hunger activity of the stomach was observed in the lizard. Subcutaneous injection of 0.6% NaCl solution does not affect contractile activity of stomach muscles. Pilocarpine in a dose 100 microgram/kg of body weight did not change the gastrogram, doses 500 and 1,000 microgram increased the frequency and the amplitude of contractions. Atropine in a low dose (100 microgram) did not affect stomach movements. Doses 500, 1,000 and 2,000 microgram induced biphasic response. Sunflower-seed oil (10 ml) decreased twofold the frequency and the amplitude of contractions within 45-60 min.
