Table 2 Weight and haematological parameters in control fed Wistar rats at each stage of the oestrous cycle

From: The impact of maternal protein restriction during rat pregnancy upon renal expression of angiotensin receptors and vasopressin-related aquaporins

  Stage of oestrus cycle (n = 6 per stage) P
  Proestrus Oestrus Metestrus Dioestrus  
Body weight (g) 234.2 ± 8.9 256.5 ± 11.6 233.9 ± 3.7 244.8 ± 9.8 NS
Kidney weight (g) 0.88 ± 0.02b 0.92 ± 0.05 0.97 ± 0.02 1.01 ± 0.02a P < 0.05
Urine volume (ml/24 hour) 16.7 ± 3.0 18.4 ± 4.5 18.7 ± 4.7 15.3 ± 1.6 NS
Red blood cells (106/ml) 7.4 ± 0.2 7.3 ± 0.1 7.5 ± 0.2 7.0 ± 0.1 NS
Haemoglobin (g/dL) 14.0 ± 0.5 13.4 ± 0.2 13.7 ± 0.3 13.2 ± 0.2 NS
Haematocrit (%) 37.9 ± 1.3 36.1 ± 0.7 36.9 ± 0.7 35.5 ± 0.8 NS
  1. Data is presented as mean ± SEM. Data was analysed by one-way ANOVA and the statistical significance of the effect of stage of oestrous is shown (NS - not significant). Superscripts denote the statistical significance of posthoc analysis, which were conducted where a significant main factor effect was found (superscript letters indicate a > b, P < 0.05).
