Iranian homograft tissue processing

Tissue transplantation is a life-enhancing therapeutic modality for damaged or non-functioning tissues. In most cases, there is no alternative other than human tissue as replacement, and taking into account the ever-increasing demand for tissue grafts, it makes sense to set up an establishment in charge of human tissue procurement to meet local needs. A quality assurance system, clearly defined...

Host-homograft Tissue Interactions following Exchange Blood Transfusions in Rabbits

Under ordinary conditions musculofascial cross-grafts made between pairs of rabbits of the same strain and species elicited classical host-homograft tissue interactions. When the cross-grafting was done 7 to 10 days after exchange transfusions leading to introduction of about 40 per cent of foreign blood, the classical host-homograft reaction failed to develop. In its stead there was an harmoni...

Homograft Immunity in Pregnancy

The effect of homograft sensitization of a mother against her fetuses has been studied. A female rabbit was repeatedly grafted from both members of a breeding pair. Their offspring should and do become objects of homograft sensitization induced in the female by grafts from the parents. After sensitization was established, fertilized ova were transplanted from the breeding pair to the sensitized...
