Abstract (2. Language): 
Effect of İmmıııısııpressive drııgs in Wodified WLC with activated IL-2. SMLC is a method which is used in choosing an adequate donor for allogeneic bone marrow transplantation (BMT) patients by detecting human leukocyte antigen (HLA)-D antigens. Besides, with this method HLA-DP and minör histocompatibility and eventually graft versus host disease (GVHD) may not be detected. Proliferative responses if exist between donor and recipient and to ameliorate BMT outcomes standart mixed lymphocyte culture (sMLC) can be modified. IL-2 was added in 25 donor-recipient combinations undergoing BMT and sMLC and we tried to detect the difference due to antigens. In 19 patients, modified MLC (mMLC) test results are found be increased. This increase is suggested to result from the differences mentioned above. Susceptibility of individuals to different immunosupressive agent varies. Susceptibility and re-sistance is important in the acceptance and rejection of the graft for this reason, this agent are added to mMLC and compare their antiproliferative effect are compared. 12 out of 26 tests show susceptibility to MeP where is 13 tests to Cyc-A. Only one test show equal resistance to Mep and Cyc-A.
Abstract (Original Language): 
Standart mixed lymphocyte culture (Standart karışık lenfosit kültürü-sMLC) allogeneik kemik iliği transplantasyonu (KİT) yapılacak hastalara uygun vericinin seçilmesinde, özellikle human leukocyte antigen (HLA)-D grubu antijenlerini saptamak için kullanılan bir yöntemdir. Bununla birlikte sMLC ile HLA-DP ve minör histokompatibilite antijenlerinin uyumsuzluğu ve bunun sonucunda oluşan graft versus host hastalığı (GVHH) belirlenemeyebilir. Alıcı ve do-nör arasında, eğer varsa saptanamayan proliferatif cevapları saptamak ve KİT'da başarıyı arttırmak amacıyla sMLC modifiye edilebilir. Bu nedenle KİT'na hazırlanan ve sMLC sonucu negatif olan, 25 bireyin farklı yönlerdeki 26 alıcı-verici hücre kombinasyonuna aynı zamanda interlökin-2 (IL-2) ilave ederek modifiye ettiğimiz MLC (mMLC) ile de bu antijenlere bağlı farklılığı saptamayı amaçladık. 19 mMLC testinde SI değerlerindeki artışında bu farklılıktan kaynaklanabileceğini düşündük. Immunsupresiflere karşı oluşan duyarlılık ve direnç bireyden bireye değişiklik göstermektedir. Bu da graftın kabul veya reddedilmesinde rol oynamaktadır. Bu nedenle mMLC testine, nakil sonrası kullanılan ajanlardan çyclosporine-A (Cyc-A) ve methylprednisolone (MeP) ekleyerek, bu ajanların antiproliferatif etkilerini karşılaştırdık. Sonuçta 26 testten 12'sinin MeP'e, 13'ünün Cyc-A'ya daha duyarlı olduğunu gördük. Bir testte ise MeP ve Cyc-A'ya karşı olan duyarlılığın eşit olduğunu saptadık.
