A study was undertaken to determine the toxic effects of cisplatin, an antineoplastic agent, on canine kidneys and bone marrow when administered during a 6-hour saline diuresis. Cisplatin (70 mg/m2 of body surface) was administered IV to 6 healthy dogs over a 20-minute period after 0.9% NaCl solution (saline) was administered IV for 4 hours at a rate of 18.3 ml/kg/hr. After cisplatin injection, saline diuresis was continued at the same rate for 2 hours. Each dog vomited within 8 hours after the drug was administered. Clinical status, weight gain, and food consumption were normal throughout the 27-day study. All measures of renal function remained unchanged and were within normal limits for 27 days after the drug was administered. Nadirs in the daily neutrophil count were observed on days 6 (3,240 +/- 404/microliter) and 15 (1,196 +/- 275/microliter). There were no important gross or histologic abnormalities referable to cisplatin administration when the dogs were necropsied at the conclusion of the study (day 27). We concluded that cisplatin can be administered safely at a dosage of 70 mg/m2 of body surface, using a shortterm diuresis protocol, and that the drug induces a ndair in the neutrophil count on days 6 and 15.

1988
Johnson, K.A.
Healing of cancellous bone graft donor sites in the proximal tibial metaphysis of 12 healthy adult dogs was studied histologically. Cancellous bone was curetted from the metaphysis of the proximal end of the tibia, via a 1-cm diameter circular opening in the medical cortex. A hematoma and fibrovascular tissue filled the bone defect at 2 weeks. At 4 and 8 weeks, endosteal callus, composed initially of cartilage and woven bone and later of lamellar bone, filled the marrow cavity. At 12 weeks, the normal structural arrangement of lamellar bone and hematopoietic marrow was reestablished in the marrow cavity. The medial cortex defect was filled only with lamellar trabecular bone. It was concluded that, in adult dogs, a second cancellous bone graft could be collected from the proximal portion of the tibial metaphysis 12 weeks or more after an initial collection.
