The Effects of Leukocyte- and Platelet-Rich Plasma (L-Prp) and Pure Platelet-Rich Plasma (P-Prp) an a Rat Endometriosis Model

Our aim was to investigate the effect of platelet-rich plasma (PRP) derivatives, which can be produced from the patients own blood and have minimal side effects, on endometriosis. To the best of our knowledge, this is the first study in the literature that studies the relationship between PRP and endometriosis. Endometriosis foci were created in the first operation. In the second operation (30th day) groups were formed. Group 1 (n= 8) was administered saline, group 2 (n= 7) leukocyte- and platelet-rich plasma (L-PRP), and group 3 (n= 8) pure platelet-rich plasma (P-PRP). Group 4 (n= 10) was used to obtain PRP. In the last operation (60th day), the endometriotic foci were measured, and then excised. There was no statistically significant difference between the pre and post volumes of the endometriotic foci, between their volume differences and volume difference rates (p > .05). However, it was observed that existing implant volumes in all groups decreased statistically significantly within their own groups by the end of the experiment compared to the previous volumes (p < .05). When the implants were assessed through histopathological scoring in terms of edema, vascular congestion, inflammatory cell infiltration, hemorrhage, epithelial line, and hemosiderin accumulation and immunohistochemical staining in terms of VEGF, there was no significant difference in the comparison between the groups. Although L-PRP and P-PRP generated more reduction in the endometriosis foci, they did not create any statistical differences.
