1. Brief treatment with angiotensin-converting enzyme (ACE) inhibitors in young spontaneously hypertensive rats (SHR) causes a persistent reduction in blood pressure associated with a relatively selective reduction in renal vascular resistance. 2. To study the possible role of the kidney in this long-term hypotensive effect, we transplanted kidneys from untreated SHR into SHR that had been treated with perindopril (3 mg/kg per day) between 6 and 10 weeks of age and also transplanted kidneys from perindopril-pretreated SHR into untreated SHR. After transplantation, the remaining native kidney was removed so that only donor kidneys remained. 3. Untreated SHR that received kidneys from perindopril-pretreated SHR showed an initial fall in blood pressure followed by a rapid increase in pressure, weight loss and early death. 4. The transplantation of kidneys from control SHR into perindopril-pretreated SHR resulted in a rise in blood pressure that obviated the long-term reduction seen normally in these animals. 5. Kidneys from perindopril-pretreated SHR may be susceptible to the high blood pressure in untreated SHR. 6. The blood pressure increase in perindopril-pretreated SHR that accompanies substitution of the native kidneys by kidneys from untreated SHR further supports the hypothesis that the kidney is responsible for the long-term pressure effects following ACE inhibition in young SHR.
