Cytophotometric evaluation of alkaline phosphatase activity in neutrophilic granulocytes and fibroblasts during wound healing in rats

The most informative indexes of alkaline phosphatase activity in neutrophil granulocytes from the peripheral blood and in neutrophil granulocytes and fibroblasts from the wound were defined in the experimental study carried out on 60 rats. These indexes were used to reveal the relationship between blood system reactions and inflammatory and regeneration processes in the wound tissue. The division of neutrophil granulocytes into three functional groups in accordance with alkaline phosphatase activity was demonstrated to be reasonable. The progress of inflammatory and regeneration processes in the wound tissues was shown to be adequately reflected in changes of both general and relative number of blood circulating neutrophil granulocytes of the third functional group characterized by high alkaline phosphatase activity. The results of the study demonstrate that the cytophotometric method is highly informative. It can be used in the clinical practice for an objective evaluation of the wound healing process as well as for an estimation of the treatment efficacy.
