| Sloth plows euterians mammals, belonging to the order Edentata, sub-order Xenarthra, infra-order Tardigrada, family Bradipodidae, which comprehend three specimen, Bradypus tridadctylus, Bradypus variegates and Bradypus torquatus. They plows few work found in the literature related to the anatomy of the placenta of this specimen. The material used in this research was consisted of 3 placentas of Bradypus variegatus of adult females (Briton, 1941) original of the Forests of the City of Recife and Zone of the Forest of the State of Pernambuco with average weight 4,2 Kg. Placentas were fixed in buffered glutaraldehyed 4%, pH 7,4, 0,1M and processed goes optical microscopy. Macroscopically was observed that the placenta of the sloth is composed of discoidal... |

| Electrocardiograms (ECG) obtained with standard limb leads and augmented unipolar limb leads were recorded from 17 unanesthetized adult sloths. The animals were held in their habitual position in an experimental chair. We determined heart rate and rhythm from the R-R intervals, the amplitude and duration of each wave, and the duration of the segments and intervals of the ECG. The mean electrical axes of P and T waves and QRS complex were calculated on the basis of the amplitude of these waves in leads I, II, III, aV R, aV L, and aV F. The P wave appeared positive in most tracings with low amplitude in lead II, the QRS complex was generally negative in leads aV R, III and aV F, and no arrhythmias were observed. With a mean ± SD heart rate for all recordings... |
