Subtotal Nephrectomy

Chronic renal failure (CRF) is associated with high incidence of cardiovascular complications. To clarify pathogenesis of CRF numerous animal models have been developed. The aim of our work was to describe methodology of subtotal surgical renal ablation in rat and to characterize some biochemical and cardiovascular parameters of this animal model. Male rats underwent 5/6 surgical nephrectomy or sham operations in two steps. The following parameters were measured on day 10 and in week 10 after the surgery: plasma concentrations of creatinine and urea, blood pressure, resting heart rate, chronotropic response to atropine and metipranol, heart ventricles weight, contraction parameters and action potential duration in the left ventricle. Increased serum concentrations of creatinine and urea, decreased creatinine clearance, polyuria and alteration of the remnant kidney tissue were found in CRF rats. Changes in cardiovascular parameters identified after subtotal nephrectomy resembled alterations of cardiovascular system in uremic patients and included hypertension, elevated resting heart rate, diminished parasympathetic cardiac tone, hypertrophy of the left ventricle associated with weakened force of contraction, prolonged contraction and relaxation and shortening of action potential duration. These data suggest that the present model can be a useful tool in the study of CRF and its cardiovascular complications.

Nighttime Sleep

Blood pressure has a diurnal pattern primarily related to activity and sleep. Chronic renal failure patients may lack the normal nocturnal decline in blood pressure during sleep. In 33 subjects (14 with normal renal function and 19 with renal dysfunction), the relationship between depth of daytime sleep, as determined by electroencephalographic sleep phase, and change in mean arterial blood pressure (MAP) and heart rate measured oscillometrically, was correlated. In 15 chronic renal failure patients, the effect of daytime and nighttime sleep on MAP and heart rate was compared. The percent change in night asleep versus day awake MAP and heart rate was measured (with Space Labs ambulatory blood pressure monitors) and compared with the percent change in daytime sleep-related MAP and heart rate measured during a daytime sleep electroencephalographic study. During daytime sleep, MAP changes are not significantly different in the normal versus renal dysfunction groups. In the 33 study subjects, MAP declines progressively from the upright position to Phase 3/4 sleep (118 +/- 3.6 to 106 +/- 3.6 mm Hg). The largest decline occurs between the upright to recumbent position, before sleep. Heart rate declines moving from the upright to recumbent position, 76 +/- 2.3 to 70 +/- 2.1 beats/min, but does not decline further with sleep. In 15 chronic renal failure patients, heart rate (10.8 +/- 2.8%; P < 0.05), but not MAP, declines during nighttime sleep. Both MAP (7.7 +/- 3.3%) and heart rate (5.4 +/- 1.9%) decline significantly during daytime sleep. The responses of MAP and heart rate to daytime and nighttime sleep were in opposite directions in 3 of 15 subjects.(ABSTRACT TRUNCATED AT 250 WORDS)
