Malignant hypertension and retinopathy in a western lowland gorilla (Gorilla gorilla gorilla).

BACKGROUND: A 34-year-old western lowland gorilla presented with peracute blindness. METHODS: Clinical evaluation, diagnostic imaging, laboratory analyses, blood pressure measurements, and necropsy were performed. RESULTS: The clinical and postmortem findings supported malignant hypertension. CONCLUSIONS: We describe a case of naturally occurring hypertensive encephalopathy and retinopathy in a gorilla.

[Utilization of the halothane test in the detection of the malignant hypertension syndrome [MHS] in pigs]. / Vyuzitie halothanového testu pri detekcii syndrómu malignej hypertermie (MHS) u osípaných.

By the halothane test we determined the development of the syndrome of malignant hyperthermia in pigs of the Belgian Landrace breed with body weight of 20 kg. We found that from 27 animals that were subjected to the test 12 positively reacted to Narcotan - Spofa anaesthesis. Pigs with the syndrome of malignant hyperthermia had considerably higher rectal temperature after anaesthesis, lower PH of venose blood, higher concentration of lactic acid and glucosis in the blood plasma. Halothane-negative animals did not produce and conspicuous changes of these indices. Most differences were statisticaly highly significant.
