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

	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 ± 0.02^b	0.92 ± 0.05	0.97 ± 0.02	1.01 ± 0.02^a	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

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).
