[A model of a rat cage for the collection of urine free of fecal matter].

A cage for total separation of feces and urine in the awake rat is presented. Construction and function are described in detail. Two important indications (investigation of the urinary enzyme activity, and determination of the endogenous creatinine clearance) are denominated.

[Perfusion machine for hypothermic pulsatile preservation of rat kidneys. Use in PUVA treatment of allogenic kidney transplants].

A machine for continuous hypothermic pulsatile perfusion preservation of rat kidneys is described in detail. The use of longwave ultraviolet irradiation during hypothermic pulsatile kidney perfusion using Euro-Collins solution containing 8-MOP did not prolong graft survival compared with untreated controls. Systemic application of 8-MOP to the kidney donor may be necessary for effective action of the combined photochemical treatment as a method of immunoalteration.
