Altered Thermoregulation in the Iguana Dipsosa Urus Dorsalis following Exercise
-1. Seven desert iguanas ran on a motorized treadmill for 20-min periods. Before, during and after exercise, the iguanas were in a thermal gradient which allowed them to thermoregnlate behaviourally. 2. For several hours following exercise, the iguanas selected warmer ambient temperatures, resulting in small, but statistically significant, increases in body temperature. 3. The increases in temp...
متن کاملCirculatory impairment induced by exercise in the lizard Iguana iguana.
Mechanical integration of the cardiac, muscular and ventilatory pumps enables mammals to vary cardiac output over a wide range to match metabolic demands. We have found this integration lacking in a lizard (Iguana iguana) that differs from mammals because blood flow from the caudal body and ventilation are maximal after, rather than during, exercise. Because Iguana iguana are constrained from v...
متن کاملPharmacokinetics of ketoprofen in the green iguana (Iguana iguana) following single intravenous and intramuscular injections.
The nonsteroidal antiinflammatory drug ketoprofen (KTP) is a commonly used antiinflammatory and analgesic agent in reptile medicine, but no studies documenting its pharmacokinetics in this species have been published. Ketoprofen was administered as a racemic mixture to green iguanas (Iguana iguana) intravenously (i.v.) and intramuscularly (i.m.) at 2 mg/kg. Pharmacokinetic analyses were perform...
متن کاملLactate and Glycogen Metabolism in the Lizard Dipsosaurus Dorsalis following Exhaustive Exercise
We evaluated the metabolic mechanisms by which the iguanid lizard Dipsosaurus dorsalis deals with the lactate which accumulates during vigorous exercise. Fasted, cannulated lizards were run for 5min on a treadmill at 40°C, which elevated whole-body lactate to 24mmoll~ and depleted hindlimb glycogen to 70% of resting levels. Oxygen consumption increased fivefold and respiratory exchange ratios a...
متن کاملAlfaxalone anaesthesia in the green iguana (Iguana iguana).
OBJECTIVE To characterise the anaesthetic effects of alfaxalone administered intramuscularly (IM) at 10, 20, and 30 mg kg(-1) . STUDY DESIGN Prospective, randomized cross-over study. ANIMALS Ten juvenile green iguanas (Iguana iguana) of mean body weight (±SD) 480 ± 134 g. METHODS Alfaxalone was administered IM in the triceps of both thoracic limbs. Times for anaesthetic induction, plateau...
