Hepatic encephalopathy in swine experimentally poisoned with Senna occidentalis seeds: Effects on astrocytes.

Senna occidentalis may be accidently ingested by humans and animals. In this study, the percentages of S. occidentalis seeds necessary for experimental reproduction of hepatic encephalopathy were determined in a pig model and the biochemical and microscopic pathology is described in detail, with emphasis on the astrocytes.

Suspected natural lysosomal storage disease from ingestion of pink morning glory (Ipomoea carnea) in goats in northern Argentina.

This study describes an occurrence of pink morning glory (Ipomoea carnea) intoxication in goats in northern Argentina. The clinical signs displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The clinico-pathologic examination revealed that the affected animals were anemic and their serum level of aspartate aminotransferase was significantly increased.

Blood and urine physiological values in farm-cultured Rana catesbeiana (Anura: Ranidae) in Argentina.

A total of 302 samples of healthy farm-cultured Rana catesbeiana specimens (9-21 months-old, 50-350 g liveweight, 50% each sex) from the north-east of Argentina, were analyzed through spectrophotometry, electrophoresis, densitometry, refractometry and microscopy in order to obtain blood and urine normal values. Confidence intervals (p<0.05) for PCV (28.
