Kolm lookust HLAA, B ja C determineerivad seroloogiliselt määratavaid transplantatsiooni ehk koesobivusantigeene, mis kuuluvad I klassi, teada on umbes 80. Põhjustavad T8 rakulise vastuse. On olemas veel nn MLC lookused (ingl k mixed lymphocyte culture). Need on lookused, mis determineerivad lümfotsüütide segakultuuride abil kindlaks tehtavaid antigeene. Sellisteks lookusteks on HLADR, HLADQ, HLADP. Need lookused determineerivad koesobivusantigeene, mis kuuluvad II klassi, teada on umbes 35. Kutsuvad esile T4 rakulise vastuse. Kudede sobivuse määramiseks doonori ja retsipiendi vahel kasutatakse mitmesuguseid uuringuid: 1) ABO-veregruppide määramine retsipiendil ja doonoril;
finding at least one abnormal result. Interfering Factors External factors such as feeding schedule, sample processing, or medications can interfere with test results. A high-fat meal prior to evaluation of a serum chemistry analysis will alter values associated with lipid metabolism and cholesterol. Diuretics may affect sodium and potassium values. Cephalosporins may cause spurious serum creatinine levels. Corticosteroids and most all chemotherapy drugs severely decrease lymphocyte levels. Lipemia may decrease sodium levels, depending on the testing method used. Corticosteroids may increase alkaline phosphatase levels. If blood samples are not processed quickly after being drawn, glucose levels will often be artificially lowered. In general, if test results do not correlate with clinical findings or expected results, the veterinarian should view the results with suspicion and consider repeating them for confirmation.

. 1 public speaking, mental arithmetic tests or benji jump), are the most validated and practical to study stress in psychology. Meta-analyses of 300 empirical studies, conducted by Segerstrom and Miller 2004, implicated that acute stressors were linked with increase in some parameters of natural immunity e.g. natural killer cells and the pro-inflammatory cytokine interleukin-6 (IL-6) and down regulation of some functions of specific immunity (e .g. lymphocyte responses). Although the steroid hormone cortisol has often been used as a psychological measure of stress however, many studies have failed to find changes in cortisol (Manuck et al, 1991), and there has been inconsistency in the effects of psychological stressors on cortisol activity (Biondi & Picardi, 1999). Despite these reports, Dikerson and Kemery (2004) in a meta-analysis of acute psychological stressors and various

T lymphocytes, T cells)- Rakud, mis arenevad luuüdis ja pärast mõningast tsirkulatsiooni vereringes liiguvad tüümusesse (harknäärmesse), kus toimub nende lõplik diferentseerumine. T-lümfotsüüdid on esmavastutavad T-rakkude vahendatud e. rakulise immuunvastuse eest. B-lümfotsüüt, B-rakk (ingl. B lymphocyte, B cell)- Tähtis rakkude klass, mis valmivad luuüdis ja küpsevad seejärel perifeerses veres. Vastutavad põhiliselt antikeha vahendatud e. humoraalse immuunvastuse eest. Nad moodustavad antikehi tootvaid plasmarakke ja mõningaid muid immuunsüsteemi rakke. 16. T-rakkude retseptorid 1.

Kasvajates on sageli apoptoos pärsitud, näiteks liigse anti apoptootilise valgu Bcl2 hulga tõttu (Bcl- B-lymphocyte lymphoma). ~50% kasvajatest on muteerunud p53 valk, mis pidurdab rakutsükli DNA kahjustumisel. Mutatsiooni korral jagunevad ka kahjustatud DNA-ga rakud. mutatsioonid välise apoptoosiraja valkudes (Fas ligand, Fas retseptor jne) võivad põhjustada lümfotsüütide hulga kasvu, mis omakorda põhjustab autoimmuunhaiguste (antikehade produtseerimine lümfotsüütide poolt omaenese valkude vastu) tekkimist. 14.)Nimetage apoptootiliste rakkude avastamise meetodeid: 1.
