background facial wrinkles develop over the natural aging process. the demand to treat these wrinkles is increasing. several treatment options are available. objectives we aimed to investigate the effect of fat injection and its combination with platelet-rich plasma (prp) on facial wrinkles. patients and methods we recruited 28 patients who were candidates for the treatment of facial wrinkles i...

frozen shoulder is a glenohumeral joint disorder that perturbs movement because of adhesion and the existence of fibrosis in the shoulder capsule. platelet-rich plasma can produce collagen and growth factors, which increases stem cells and consequently enhances the healing. to date, there is no evidence regarding the effectiveness of platelet-rich plasma in frozen shoulder. a 45-year-old man wi...

Abstract Background Autologus platelet gel is easy to prepare and is relatively low cost. The aim of this study was to prepare and evaluate in vitro efficacy of autologus platelet gel. Materials and Methods In this experimental study, platelet concentrate and platelet poor plasma were prepared with aphaeresis method. Thrombin was prepared by mixing the plasma with calcium. Thrombin activity...

background  many biomaterials are used during the open sinus lift surgery, beneath the elevated scheniderian membrane and maxillary sinus bony floor but the search for ideal material continues. methods  in the maxillary posterior atrophic ridges with the bone height less than four millimeters the open sinus lift surgery performed. the autologous platelet-rich plasma (prf) was used as the sole g...

objectives effect of using autologous platelet-rich plasma (prp) on pain reduction in patients with pilonidal abscess, subjected to extensive surgical removal tissue, was investigated through a clinical trial. patients and methods the trial was conducted on two groups from the center for surgical research at mashhad university of medical sciences located at ghaem hospital in mashhad city in 201...

objective: at present, growth factor-containing products such as enamel matrix derivatives, recombinant bone morphogenetic protein (rh-bmp), recombinant platelet derived growth factor and platelet rich plasma (prp) have gained increasing attention. prp is an autologous source of platelet growth factors used to enhance healing of soft and hard tissues. prp has gained popularity due to its autolo...

OBJECTIVES The purpose of this study was to investigate whether platelet-rich plasma (PRP) enhances osseous healing in conjunction with a high tibial osteotomy in dogs. STUDY DESIGN Randomized controlled trial. METHODS Sixty-four client-owned pet dogs with naturally occurring rupture of the anterior cruciate ligament and that were to be treated with a high tibial osteotomy (tibial plateau l...

background the platelet-rich plasma (prp) and hyaluronic acid (ha) constitute a system of tissue growth that can regenerate damaged tissue. this study was performed to evaluate the effect of prp and ha in treatment of complications of achilles tendon reconstruction. methods we selected ten patients affected by achilles tendon injuries resulting from post-surgical complications subsequent to ten...

background clinical tendon injuries represent serious and unresolved issues of the case on how the injured tendons could be improved based on natural structure and mechanical strength. the aim of this studies the effect of aquatic activities and alogenic platelet rich plasma (prp) injection in healing achilles tendons of rats. methods forty rats were randomly divided into 5 equal groups. sevent...

background:the utility and efficacy of novel materials in tissue regeneration and antimicrobial therapy are contingent upon the employment of either blood derivatives rich in platelets or platelet-poor-plasma (ppp). this effect is largely mediated by the increased or decreased concentration of platelets in the plasma. the current study aimed to analyze and evaluate the impact of platelet-rich (...
