objectives : platelet preparations are commonly used to enhance bone and soft tissue regeneration. considering the existing controversies on the efficacy of platelet products for tissue regeneration, more in vitro studies are required. the aim of the present study was to compare the in vitro effects of plasma rich in growth factors (prgf) and platelet-rich fibrin (prf) on proliferation and viab...

BACKGROUND Platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. The primary objective of this study was to use autologous platelet rich plasma (PRP) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. METHODS In a single ...

background recently, the clinical use of low power lasers has increased, and it is said that wound healing is accelerated by their irradiation. the aim of this study was evaluation of the effect of platelet-rich plasma on proliferation and differentiation of human dental pulp stem cells with or without ga-al-as laser. methods: in this experimental study, human lower third molar dental pulp cell...

Partial thickness rotator cuff tears (PTRCTs) are a common pathology among shoulder disorders in people over 50 years.Treatment of PTRCTs remains controversial. Most studies on the treatment of PTRCTs have explained surgical techniquesor outcomes; few studies have centralized on the conservative and new management of PTRCTs, like treatmentwith Platelet-rich plasma (PRP). These case series study...

BACKGROUND Platelet-rich plasma (PRP) is an autologous concentration of human platelets in plasma. In this paper, we aimed to investigate the effect of PRP on hair growth. METHODS Platelet-rich plasma and platelet-poor plasma were prepared by sterile centrifugation and injected into shaved dorsal skin of mice (n = 10). Saline injection was used in the control group. The length of randomly plu...

Due to controversial evidence in the literature pertaining to the activity of plasminogen activator inhibitor-1 in platelets, we examined the effects of residual platelets present in plasma (a potential pre-analytical variable) on various plasminogen activator inhibitor-1 and plasminogen activator inhibitor-1-related assays. Blood samples were collected from 151 individuals and centrifuged at 3...

Introduction: Platelets are small, anucleated cytoplasmic fragments that play an essential role in blood clotting and wound healing. Platelets are routinely stored in plasma for five days at 220C. Aim: Our objective was to assess platelet morphology and function in random donor platelet stored for seven days in platelet additive solution. Methods: The random donor platelet was prepared by PRP m...

Treatment of severe Immune Thrombocytopenic purpura (ITP) accompanied by life-threatening bleeding events is challenging and a combination of treatment measures should be undertaken to rapidly increase the platelet count. Herein, we report a case of severe ITP in a seven-year-old boy who suffered from massive bleeding which was totally unresponsive to conventional therapeutic interventions. Sin...
