We investigated the serum concentrations of zinc and copper during the inflammatory process together with the effect of treatment with a nonsteroid anti-inflammatory agent on these trace elements concentrations. In the present study, we used 92 guinea pigs, 12 of which constituted the control group; the remaining 80 were the experimental group. To start with, proquazone (as anti-inflammatory agent) was administered orally to 40 guinea pigs of the experimental group at 20-mg/kg doses 2 h before the surgery. Throughout the experimental period, the above dose was administered to the animals twice a day. We produced inflammation in all animals of the experimental group by using carrageenan (inflammatory agent) dropped into mandibular surgical defects. Serum concentrations of zinc and copper were determined by atomic absorption spectrophotometry in both groups at the 6th, 48th, 120th, 168th, and 240th h. The serum zinc concentrations of the carrageenan-administered group decreased significantly (p<0.01). When comparing the serum zinc concentrations of the carrageenan plus proquazone-administered group with those of control group, the decrease (p<0.05) at the 6th, 48th, and 120th h were statistically significant. When the copper serum concentrations of the carrageenan-administered group were compared with those of the control group, at the 48th, 120th, and 168th h, a statistically significant increase (p<0.01) was observed. However, there was no significant change in the carrageenan plus proquazone-administered group at the 168th and 240th h. As a result during the acute phase of inflammation, serum zinc concentrations decreased, whereas serum copper concentrations increased. The alterations in zinc concentrations were more rapid than those in copper concentrations, but the administration of proquazone slowed the rate of decrease in serum zinc concentrations.
