Background: Platelet Rich Plasma (PRP) contains Growth Factors (GFs) and antiinflammatory agents with possibility of application in regeneration of damaged cartilage in the treatment of osteoarthritis (OA). In the most trials, three injections of PRP have been done but in this research we assessed the efficacy and safety of single injection of PRP in the management of OA. Methods: In th...

In some patients, however, symptom relief is not achieved even after surgery, or the disease recurs and patients must return for revision surgery .many patients whose symptom...

سابقه و هدف: روش اصلی جداسازی میکروپارتیکل‌های پلاکتی(PMP) بر اساس دور سانتریفیوژ و زمان می‌باشد. با توجه به هزینه ‌بالای تعیین تعداد PMP از طریق میکرو‌ذرات (micro-bead) و هم‌چنین ضرورت استفاده از دستگاهی پرهزینه مانند فلوسایتومتر، به نظر می‌رسد تعیین غلظت PMP به روش برادفورد روشی ارزان، سریع و به‌صرفه می‌باشد. بنابراین در این مطالعه تاثیر فاکتورهای دور و زمان‌های مختلف سانتریفیوژ و زمان فریز ...

Platelet-rich plasma (PRP) is a solution derived from whole blood that is enriched in the platelet fraction. Platelets serve as a reservoir of growth factors and cytokines. When platelets are activated in vivo, signaling molecules are released into the immediate microenvironment and activate receptors for various pathways. PRP has been applied to bedsores to promote healing. Over the last decad...

Introduction: Several methods have been proposed for the treatment of knee osteoarthritis pain like as platelet rich plasma. The aim of this study is to compare adding intraarticular growth hormone to platelet rich plasma under sonographic guidance on joint function in knee osteoarthritis . Materials and Methods: Fifty four patients with knee osteoarthritis divided into two equally groups inclu...

Background: Velopharyngeal insufficiency causes hypernasal vocal quality and can also result in audible nasal air emission and difficulty in producing pressure consonants. The resulting speech is often socially unacceptable and can be difficult to understand. Platelet-rich plasma is an autologous derivative of whole blood. Today, the importance of clinical use of Platelet-rich plasma in the pla...
