An allometric method for estimating the volume change in inflamed paw of rats is described. The technique is effective and advantageous for long term observation of adjuvant arthritis which lacks a suitable reference criterion due to the simultaneous swelling of the control paw. In the present method, the inflammatory intensity (IF) of paw edema is estimated by means of the formula: IF(%)={2V<SUB>t</SUB>/cX<SUP>d</SUP>(I÷W<SUB>t</SUB>/aX<SUP>b</SUP>)-I}×100 where V<SUB>t</SUB> is the paw volume, W<SUB>t</SUB> is the body weight and X is the tail length of the inflamed rat. The constants a, b, c and d are obtained from the normal rats using the relative growth law, W=aX<SUP>b</SUP> and V cX<SUP>d</SUP> (where W is the body weight, V is the paw volume and X is the tail length).
