The viability of chondrocytes in press-fit glycerol-preserved osteochondral allografts was compared to that in fresh autografts, after transplantation into load-bearing and non-load-bearing sites in mature sheep stifle joints. We used macroscopic grading, tonometer pen indentation testing, histology, sulfate uptake and viability as determined by confocal-microscopy to assess cartilage condition...

OBJECTIVES To compare bone-patellar tendon-bone autografts with hamstring autografts for reconstruction of the anterior cruciate ligament. DATA SOURCES Medline, WebSPIRS, Science Citation Index, Current Contents databases, and Cochrane Central Register of Controlled Trials. Review methods All randomised controlled trials reporting one or more outcome related to stability (instrumented measure...

In 1959, experiments were begun to provide a more physiological and permanent pacemaker for chronic heart block by placing an autotransplant of either adrenal medulla or thyroid gland into the ventricular myocardium of dogs with complete heart block. The original concept was that the small area of myocardium surrounding the endocrine transplant would be stimulated by relatively high local conce...

Serial roentgenograms of 40 patients who had 70 cervical intervertebral spaces grafted with ethylene oxide sterilized cadaver bone and 28 patients who received 44 iliac crest auto grafts for anterior cervical spine fusion, were studied. The radiological evaluation was made on the basis of settlement of intervertebral spaces, fusion rate, delayed union, non-union, graft collapse and extrusion of...

The use of cultured epithelial autografts for the treatment of extensive burn wounds has become popular in recent years. We examined extensive burn wounds in 14 patients by using a combination of autograft and cultured epithelial autografts developed in Japan (JACE). METHODS We undertook a skin biopsy at 2, 4, and 6 weeks after transplantation with JACE. By using electron microscopy we observ...

Background Previous meta-analyses have compared bone-patellar tendon-bone (BPTB) with hamstring tendon (HT) autografts for primary anterior cruciate ligament reconstruction (ACLR). Purpose To conduct a systematic review of overlapping meta-analyses comparing BPTB with HT autografts for ACLR to determine which meta-analyses provide the best available evidence. Study Design Systematic review;...

Although grafting is widely used in the agriculture of fruit-bearing crops, little is known about graft union formation in particular when two different species are grafted together. It is fascinating that two different plant species brought together can develop harmoniously as one organism for many decades. The objective of this study was to determine whether grafting two different grapevine g...

In order to develop autologous tissue engineering of the whole wall in the urinary excretory system, we studied the regenerative capacity of the muscular bladder wall. Smooth muscle cell expansion on minced detrusor muscle in vitro and in vivo with or without urothelial tissue was studied. Porcine minced detrusor muscle and urothelium were cultured in vitro under standard culture conditions for...
