The Investigation of Platelets' Response to Epinephrine Using Optical Aggregometer and PFA–100
Abstract
In this study we aimed to examine the response of platelets to epinephrine using optic aggregometer and PFA-100. Blood samples of 68 healthy and volunteered subjects, aged between 20-76, were evaluated for the epinephrine responses of platelets by using collagen/ epinephrine and collagen/ADP cartridges in PFA-100 system for closure time values. The process of aggregation was observed for 10 minutes by adding 10μM ADP, 10 μg/ml collagen or 300 μM epinephrine on platelet rich plasma (450 μl) prepared for aggregation tests. The samples were classified into three groups as nonresponder, semiresponder and normal according to their maximal responses to epinephrine: 14,7 % nonresponder, 16,2 % semiresponder were observed. A decreased response to epinephrine was associated with increased epinephrine lag duration, decreased maximum aggregation of ADP and increased collagen lag duration. The PFA-100 system collagen/ epinephrine cartridge closure time values were observed to be increased in the groups with nonresponder and semiresponder. Our results acquired with optic aggregometer demonstrate that the responses of platelets to epinephrine is various, and the relatively new method of PFA-100 can also be used to evaluate this response.
