background and aims. since intracanal medicaments can affect the cell viability in periapical tissues, the aim of this study was to evaluate the effect of calcium hydroxide and propolis on pulp fibroblasts. materials and methods. two healthy third molars were used as a source to obtain fibroblasts. the fibroblasts were cultured and subjected to 1 mg/ml of propolis and calcium hydroxide. this ex...

this study was designed to examine the effects of retinoic acid adding to cumulus and/or fibroblast cellsmonolayer on the development of mouse early embryos. one-cell mouse embryos were obtained from nmrimice after superovulation by an intraperitoneal injection of 5 iu equine chorionic gonadotrophin (ecg)followed 48 hrs later by 5 iu human chorionic gonadotrophin (hcg). mouse embryonic fibrobla...

Objectives- Tendons are integral parts of musculoskeletal system and are subjected to injury. Fibroblast is used in tendon healing, however, there is no proved and reported result regarding concurrent use of allogenic fibroblast with static magnetic field in tendon healing. In addition, there are some studies done on the effect of magnetic fields on tendon healing but the results are antithesis...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 one of the prominent types of connective tissue cells is fibroblast that synthesizes and maintains the extracellular matrix of many animal tissues. previous studies illustrated that calprotectin protein has different cytotoxicity effects on fibroblast cells. calprotectin is abundant in the neutrophil cytosol; it has growth...

introduction: one of the major contributing factors, which may cause failure of endodontic treatment, is the presence of residual microorganisms in the root canal system. for years, most dentists have been using calcium hydroxide (ch) as the intracanal medicament between treatment sessions to eliminate remnant microorganisms. reducing the size of ch particles into nanoparticles enhances the pen...

background tendon injuries are common and it takes a long time for an injured tendon to heal. adverse phenomena such as adhesion and rupture are associated with these injuries. finding a method to reduce the time required for healing whichimproves the final outcome, will lead to decreased frequency and intensity of adverse consequences. this study was designed to investigate the effects of basi...

avulsion is one of the most serious emergencies in dental office. in the event of any problem, the tooth should be stored in a medium that supports the periodontal ligament cell viability. in other clinical situations, preserving media, growth factors and mitogenic products may be useful in repairing the traumatized tissues. it has been previously reported that levodopa (l-dopa) accelerates hea...
