INTRODUCTION In a large proportion of patients with chronic urticaria, a coexisting autoimmune type of Hashimoto's thyroiditis is being diagnosed. An intradermal test with autologous serum has been generally considered as a screening procedure indicating the presence of triggering autoimmune inflammatory factors in the sera of patients with urticaria. These factors could be possibly involved in...

Hebbel and colleagues have proposed that increased adherence of sickle red cells to vascular endothelium may initiate vasoocclusive events in sickle cell disease. We have developed a micropipette technique to obtain direct, quantitative measure of the adherence of individual red cells to vascular endothelial cells. Using this technique, we found that the vast majority of sickle cells suspended ...

The etiological factors of erythema the face in rosacea are analyzed article. role vasoactive peptides, inflammatory mediators and ticks genus Demodex pathogenesis disease has been determined. main methods treatment considered, including phototherapy with narrowband pulsed radiation platelet autologous plasma (TAP). Current data indicate acceleration natural mechanisms skin regeneration due to ...

The purpose of this study was to evaluate a new technique of harvesting and preparing autologous platelet gel and autologous fibrin glue (body glue) and to evaluate their effectiveness in stopping capillary bleeding in the surgical flaps of patients undergoing cosmetic surgery. A convenience sample of 20 patients ranging from 25 to 76 years of age undergoing cosmetic surgery involving the creat...

The current study aims to evaluate the macroscopic and histological effects of autologous mesenchymal stem cells (MSC) and platelet-rich plasma on knee articular cartilage regeneration in an experimental model of osteoarthritis. Twenty-four rabbits were randomly divided into four groups: control group, platelet-rich plasma group, autologous MSC undifferentiated group, and autologous MSC differe...

OBJECTIVE The present study was performed in order to evaluate the use of platelet rich plasma associated to bone marrow aspirate, substituting autologous iliac bone graft in medial opening wedge osteotomy (OWHTO). METHODS Twenty-five patients were submitted to tibial opening wedge osteotomy, being divided into two groups. Iliac group: 14 patients submitted to OWHTO, using autologous iliac bo...

Two hundred patients were selected and comprised two statistically balanced group of 100 each. Group one received whole bank blood and plasma following extracorporeal circulation and again when further blood replacement was necessary. Group two received autologous transfusion following extracorporeal circulation and homologous bank blood and plasma when further blood replacement was necessary. ...

INTRODUCTION Worldwide estimates are that 9.6% of men and 18.0% of women aged over 60 years have symptomatic osteoarthritis. The current treatment options vary from conservative to joint replacement. Recently, debridement of the joint has become an option for symptomatic relief. We evaluated the outcome of arthroscopic debridement with autologous conditioned plasma. The latter helps to promote ...

BACKGROUND To explore the possibility that antibody-mediated complement lysis contributes to viremia control in HIV-1 infection, we measured the activity of patient plasma in mediating complement lysis of autologous primary virus. METHODS AND FINDINGS Sera from two groups of patients-25 with acute HIV-1 infection and 31 with chronic infection-were used in this study. We developed a novel real...
