Spina bifida in a German shepherd puppy.

A case of spina bifida in a German shepherd puppy is described. The puppy, which was dead when delivered by caesarian section, had an obvious cleft in the skin and soft tissues overlying an area of kyphosis in the lumbar region. Radiographic examination and bone staining techniques revealed an extensive bony defect with a failure in approximation of the vertebral laminae dorsally from T3 to Ca5.

Renal biopsy in the normal cat: an examination of the effects of a single needle biopsy.

Eleven healthy cats were subjected to a single, percutaneous renal biopsy with a disposable biopsy needle and thereafter monitored clinically and by means of laboratory analyses of blood and urine until euthanasia at intervals up to two months after biopsy. Biopsy specimens were obtained at each attempt and the specimen length and numbers of glomeruli compared favourably with results from normal dogs biopsied with Franklin-Silverman needles. At necropsy radiographic studies demonstrated renal vascular changes and histological examinations of the biopsied kidneys revealed lesions varying from barely discernible linear scars to extensive haemorrhage and wedge-shaped infarcts. A direct relationship was established between the severe renal lesions in seven cats and biopsy specimens containing medullary tissue and major renal blood vessels.

Congenital deformities in two Clydesdale foals.

The deformities observed in 2 Clydesdale foals are described. Both had abnormal joint positions in the forelimbs and discrepancies in the symmetry of the vertebral column. The changes were only mild in one case but extreme in the other where it was accompanied by torticollis, scoliosis and vertebral fusion. A comparison is made with deformities described in the contracted foal syndrome and some of the developmental implications discussed.

A preliminary report on the use of a chronic peritoneal fistula for endoscopic examination of ovine ovarian activity.

A description is given of a technique devised to allow repeated endoscopic observations to be made of ovarian changes occurring during an oestrus cycle in the ewe. The use of a chronic peritoneal fistula is illustrated and the methods used to maintain its patency discussed. The technique was carried out in a small number of ewes and the ovarian changes occurring in an ovary of one of these ewes, over a 22 day period, are shown in photographic and diagrammatic form.
