A Japanese Black calf, manifested by clinical signs of inability to stand and extending hind limbs after birth, was investigated clinically and pathologically. In the neurological inspection, gastrocnemius reflex and patellar tendon reflex of the right hind limb were hyperactive, and gastrocnemius reflex and crossed extension reflex of the left hind limb were also hyperactive. Magnetic resonance imaging (MRI) examination showed a cavity in the cord at the area of the third and fourth lumbar vertebrae in T2-weighted imaging.

GM2 gangliosidosis variant 0 (Sandhoff disease, SD) is a fatal, progressive, neurodegenerative lysosomal storage disease caused by simultaneous deficiencies of acid β-hexosaminidases A and B. Canine SD has so far been identified only in two purebreeds. In this article, we present the case of a 10 mo old, male dog of mixed breed that developed progressive neurological signs including ataxia, postural deficit, and visual deficits and finally died at the age of 21 mo.

The relationship between methylmercury (MeHg) exposure and aquaporin (AQP) expression in the brain is currently unknown. To investigate this, we used a common marmoset model of acute MeHg exposure to examine AQP1, AQP4 and AQP11 gene expression. MeHg (1.

The T-wave of the patellar tendon reflex (PTR) was recorded in 24 neurologically normal dogs. The surface electromyogram (EMG) was recorded as the T-wave from the vastus lateralis muscle (VL) in response to percussion of the patellar tendon. The distance of the reflex arc (DRA) was measured along the straight line between the spinous process of L5 and the greater trochanter (GT), and between GT and the patellar ligament (PL).

A 22-month-old male Japanese mongrel cat with a history of dysuria and recurrent generalised tonic-clonic seizure was examined by neuro-opthalmological testing and computed tomography (CT). Vision testing revealed narrowing of the visual field in the right eye, and complete visual deficits in the left eye. Pupillary reactions, and motor and sensory function in the eyelids and the eyes were normal.

Perchloric acid-soluble protein (PSP) is a members of a new hypothetical family (YER057c/YJGF family) of small proteins with presently unknown function. The high degree of evolutionary conservation of these proteins reflect an involvement in basic cellular regulation. The expression of PSP was examined in rat hepatoma cell dRLh 84-beared rats.
