Ocular lesions are a common manifestation of toxoplasmosis in cats. In this survey, 10 healthy Syrianmice were infected through intraperitoneal inoculation of bradyzoites of Toxoplasma gondii (Tehran strain).Mice were killed 30 days after inoculation and the suspension of their brains was prepared, after confirmationof the infection. Seven kittens were fed with the infected mice brain suspensio...

Bacterial infection of the brain is relatively rare in dogs and cats. A cat at approximately three months of age was admitted to the clinic with a history of dog bite seven days before admission. On clinical presentation, the cat was unconscious and in lateral recumbency. One hour after admission, the cat developed severe apnoea and asystole. Cardiorespiratory resuscitation was unsuccessful and...

BACKGROUND Mucopolysaccharidoses (MPS) are common lysosomal storage disorders causing typically progressive skeletal and ocular abnormalities. OBJECTIVES To describe the clinic features, metabolic profile and a unique mutation in a domestic shorthair (DSH) kitten with MPS VII. ANIMALS Affected kitten and 80 healthy cats. METHODS Serum lysosomal enzyme activities and urinary glycosaminogly...

IN THE NORMAL CAT OR KITTEN about four-fifths of cells in the striate cortex can be driven by both eyes (3, 4). If, however, one eye of a newborn kitten is sewn shut and the visual cortex recorded from 3 months later, only a small fraction of cells can be driven from the deprived eye (8) . In contrast, many cells in the latera .I geniculate are driven normally from the d ,eprived eye (7 ), sugg...

To assess the possibility that NMDA receptors play a special role in visual cortical plasticity, the selective antagonist 2-amino-5-phosphonovaleric acid (APV) was continuously infused into the striate cortex of kittens as the visual environment was manipulated during the critical period. The cortex was studied using single-unit recording from sites between 3 and 6 mm from the infusion cannulae...

We studied the effects of graded hypoxia on mechanical performance of cardiac ventricular muscle by producing controlled, stepwise decreases in partial pressure of oxygen (Po2) in the medium bathing the kitten papillary muscle preparation and in the perfusate of the Langendorffprepared rabbit heart. For kitten papillary muscle at 30°C and with stimulation rate at 30/min, maximum rate of contrac...
