This study had a standardization of rat strains for the transplant-immunology and establishment for screening systems of imuunosupresive matters as the purpose.
1. The grasping base line data of each rats strains
The base line datas were settig up datas that measured the breeding, growing (body and organs weight) and hematological of 7 rat strains (ACI/N,BN/SsN,F344/SsN,WF/N,WM/Ms, and WKAH/HoK). These datas were showed individuality of each rat strains that the strains of WF/N and BN/SsN were low number of delivery, the strain of ACI/N was small body weights, the strain of LEW/SsN was heart and liver of large size, the strain of WF/N was testis of small size, the strain of WKAH/HoK was large number of lymphocytes and the strain of WF/N was small number of platerets.
2. To estabulished the experimental animals for screening systems of imunuosupresive matters
The two combination of donor and recipient for rat cadiac allotransplantation were useful for screening systems of imuunosupresive new matters which took the strong rejector of ACI/N colony to LEW/SsN colony and the middle rejector of LBNF1 colony to LEW/SsN.colony
3. The basis investigation for rat immune system
Beige rat of low NK cell activity and nude rat of losing T cell activity were used throughout the experiment that wer rat cadiac allo-and xeno-transplantation. Its tested graft suvival time and pathology.
There was not significantly correlation of allogeneic cardiac grafts survival between Beige rat and allo and xeno cardiac graft. The nude rat recipients prolonged allografts survival, but xenograft survival was not prolongation. Then T cell immune system were responsed to rejection of allograft, but the rejection of xenograft were unresponsed.
