A suspension of washed human erythrocytes (2%) in PBS was mixed with an equal volume of 1 mM glutaraldehyde (GA) and allowed to stand at laboratory temperatures, followed by washing with normal saline. The agglutinability of the erythrocytes toward anti-A, anti-B, anti-M and anti-N reagents remained unchanged after GA treatment shorter than 20 minutes, and the agglutinability toward anti-C, anti-c, anti-D, anti-E, anti-e, anti-Lea, anti-Leb and anti-P1 did not decrease after treatment for 10 minutes. GA treatment for longer periods of time than the above caused a decrease of the reactivities. The agglutinability toward an anti-H (Ulex europaeus) and other lectins increased after 10 to 30 minutes of GA treatment and decreased after 40 minutes or more of exposure to GA. These results indicate that the immunologic agglutinability of erythrocytes were practically unchanged after a 10 minutes treatment with 1 mM GA (a mild fixation procedure hereafter called "partial fixation"). The properties of the partially fixed erythrocytes were closely similar to those of untreated erythrocytes as regards cell volume, membrane fragility in hypotonic solutions (measured by a modification of the Ribiere method), and membrane fragility under continuous
shaking
. The resistance of the partially fixed erythrocytes heating up to 50 degrees C was superior to that of the untreated erythrocytes. From these results, the deformability of the partially fixed erythrocytes was concluded to be similar to that of untreated erythrocytes. After storage for 6 months at 4 degrees C in Alsever solution containing adenine and inosine, the shapes of the untreated erythrocytes changed to "spherocytes" or "echinocytes", whereas the partially fixed cells retained the original discocyte shape. Blood grouping laboratory tests were performed with the partially fixed erythrocytes as indicators. Both anti-A and anti-B agglutinins in normal human sera could be detected without difficulty. Presence of irregular agglutinins, such as anti-H and anti-N, in healthy donors' sera could also be detected, as with the freshly obtained erythrocytes. The detection limits of an incomplete anti-D agglutinin were equal to those in the tests with untreated erythrocytes. The partially fixed erythrocyte (stored at 4 degrees C for 2.5 to 3 months) were used as indicators of
ABO
-blood grouping from blood stains, saliva stains and hairs by the agglutinin-inhibition test, absorption-elution test or mixed agglutination test. The results obtained were practically equal to those of the tests with freshly obtained erythrocytes, indicating the availabilities of the partially fixed erythrocytes.

The new immunosuppressive agent FK506 was used with steroids to treat 22 pediatric patients who received living-related partial liver transplantation. Seventeen recipients survived and 5 died between one and 16 months after transplantation. Three of the 5 patients who died had required intensive care preoperatively. Autopsy findings showed no evidence of rejection. There was no episode of rejection that required retransplantation in any of the patients. Liver allograft dysfunction, which was suspected to be a rejection response, was encountered in 2 recipients with
ABO
-nonidentical but compatible grafts. However, their clinical and biochemical findings were ameliorated upon steroid pulse therapy or upon augmented FK506 administration without additional potent immunosuppressive agents. Steroid treatment has been discontinued in all surviving patients at 1-9 months after transplantation. Infectious complications encountered in 9 patients included 2 bacterial, 5 viral, and 2 fungal infections. One recipient died of fungal pneumonia. Abnormal increase of serum creatinine level was confined to the complicated patients. Hypertension was a temporary adverse reaction in the early postoperative period, and only one patient needed an antihypertensive drug at 2 months after transplantation. Acute pancreatitis with hyperamylasemia was observed in one patient who was treated successfully with reduction of FK506 administration.
Tremor
was observed in 8 patients, itching in 4, insomnia in 2, and vomiting in one. Hirsutism, gingival hypertrophy, and lymphoma were not observed. FK506 was highly effective in living-related partial liver transplantation not only in terms of immunosuppressive potential but also because it produced fewer adverse effects.

Recently, new calcineurin inhibitors, such as tacrolimus (FK-506) and microemulsion cyclosporin, have been approved for maintenance immunosuppression in renal transplant recipients and short-term outcomes have been accumulating. In the majority of patients, these calcineurin inhibitors have been used in combination with new immunosuppressive drugs, such as mycophenolate mofetil (MMF) or sirolimus. Under these circumstances, a comparison of cyclosporin and tacrolimus provides the answer to a very important controversial issue. Which drug should we choose in individual patients? In an attempt to answer this question, this review compared the use of tacrolimus and cyclosporin in modern immunosuppressive regimens, which have already been published in well designed clinical studies, and discusses how immunosuppression should be individualised in renal transplant patients.Overall, short-term patient and graft survival with cyclosporin microemulsion and tacrolimus is almost identical. The incidence of acute rejection is generally lower in tacrolimus/azathioprine- than in cyclosporin/azathioprine-treated patients. However, in conjunction with MMF, the difference in the incidence of acute rejection between tacrolimus- and cyclosporin-treated patients became smaller. Adverse events, such as hypertension, hyperlipidaemia and cosmetic changes (gum hypertrophy, hirsutism) seem to be less frequent in tacrolimus-treated than in cyclosporin-treated patients. Recent randomised studies showed that the incidence of post-transplant diabetes mellitus was almost identical between low-dose tacrolimus- and cyclosporin-treated patients. According to the data discussed in this review, the recommendation on the choice of calcineurin inhibitors at this moment is that either cyclosporin or tacrolimus can be used safely and effectively for patients without any risk factors. However, at our centre, we prefer tacrolimus to cyclosporin in patients with a high risk for rejection, such as those with
ABO
-incompatibility, delayed graft function, sensitisation, and African American race and some other risk factors, such as hypertension and hyperlipidaemia. Moreover, tacrolimus may be preferable to cyclosporin for women because of hirsutism and for children because of the steroid-sparing effect. We consider that cyclosporin should be chosen when patients experience tacrolimus-related adverse events, such as severe chest pain,
tremor
, gastrointestinal symptoms and encephalopathy. In conclusion, well tolerated and effective immunosuppression is feasible with both cyclosporin and tacrolimus. In the current immunosuppressive regimens, a calcineurin inhibitor, either tacrolimus or cyclosporin, is the essential basic standard immunosuppressant. Clinicians need to decide the best means of optimising therapy for individual patients, based on various risk factors, such as risk of rejection, i.e. sensitisation, delayed graft function and
ABO
-incompatibility, and some adverse events, such as hypertension, hyperlipidaemia and cosmetic changes.
