Nitrogen excretion during embryonic development of the green iguana, Iguana iguana (Reptilia; Squamata).
Development within the cleidoic egg of birds and reptiles presents the embryo with the problem of accumulation of wastes from nitrogen metabolism. Ammonia derived from protein catabolism is converted into the less toxic product urea or relatively insoluble uric acid. The pattern of nitrogen excretion of the green iguana, Iguana iguana, was determined during embryonic development using samples f...

متن کاملLight and scanning electron microscopy of the developing lingual papillae in the green iguana, Iguana iguana
Reptiles have recently become a popular group of pet animals. A relatively large number of studies on the morphology of the oral cavity and method of feeding in adult individuals have been published. Nevertheless, embryological descriptions of reptile body parts or structures are rare. In this study, we describe the morphology of the developing tongue, in particular its dorsal surface, in pre-h...
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 کاملOxygen transport by the circulatory system of the green iguana (Iguana iguana) at different body temperatures.
Since the early investigations of Cowles & Bogert (1944), it has become established that many lizards when active under natural conditions have mean body temperatures that are several degrees higher than air temperature in the shade and are relatively constant (Brattstrom, 1965). This difference between the mean (or eccritic) body temperature and air temperature is maintained primarily by absor...
