The body weight gain of the rats changed during the 91 days of continuous inclusion of the heavy metal salts. During examination, body weights increased after the daily intake of MnCl2, ZnSO4 or BeSO4, but the other salts of Pb, Cd, Cu, Hg decreased the body weights, each compared with the controls. These effects were possibly caused by changes in feeding and drinking habits: The daily consumption of standard diet (pellets) increased during dosing with the salts of Mn, Zn or Be and decreased during treatment with the other heavy metal salts. The salts of Be and Mn enhanced consumption of drinking water, and the salts of Zn, Pb, Cu, Cd or Hg reduced consumption of drinking water, each compared with the controls. Most effective was Hg2(NO3)2.

On the first day of testing the groups did not differ with respect to the paw-lick latency before footshock. However, the paw-lick latency after footshock (the index of stress-induced analgesia) was significantly longer in rats exposed to the higher dose of CVP (3.0 mg/kg) than in the control animals. Twenty four hours later, in the control animals, the paw-lick latencies before footshock were shortened in comparison with those recorded on the day before.
