Academic Journal of Second Military Medical University 1985;0(06):-
UW solution has bean considered the gold standard for abdominal organ preservation. Celsior solution and HTK solution, with low potassium and low viscosity, are becoming more widely used in the preservation of the kidney, liver and pancreas, and are gradually accepted as an ideal alternative for UW solution. Recent studies have found that addition of trophic factors can attenuate hypothermic ischemic injury to the donor organ, thus improving the preservation outcome. This paper reviews the progress in laboratory research and looks foward to the clinical application of multi-organ preservation solution.

Retrospective analysis of 761 case-times successive color Doppler sonography for 518 renal transplant patients was carried out.six parameters of sonography were used to compare, the CsA-NT hemodynamic changes among the patients with normal function, rejected and hy-dronephrotic kidney.It revealed that during rejection of the rendl srafts, besides an elevation of resistance index(RI)and a decrease of D/S ratio, the velocity and volume of renal blood flow were also slowed down and decreased respectively.After combating rejection, the renal function recovered to normal gradually, and RI dropped below 0.75 subsequently.Otherwise R1 would be persistently elevated, which indicated an irreversible rejection.The diagnosis of acute rejection was given at RI≥0.83, with the sensitivity rate being 82.70%and specificity being 80.10%.It was suggested that RI is a relatively sensitive and relialble parameter for the diagnosis of rejection.In combination with the clinical manifestations RI is of great important clinical value for the early diagnosis and treatment of acute rejection.

Objective To study the therapeutic effects and side effects of foscarnet in the treatment of active(IgG+,IgM+)and inactive(IgC+,IgM-)cytomegalovirus(CMV)infection after cadaver renal transplantation.Methods Forty-one cases of active cytomegalovirus infection and 22 of inactive cytomegalovirus were selected to receive foscarnet treatment.Besides,10 cases of inactive cytomegalovirus infection served as control group without receiving foscarnet.The usage of foscarnet was 40 mg/kg,iv.,2 ~3 weeks in the active stage,50 mg/kg,iv.,3~4 weeks in the inactive stage.Results Clinical symptoms of patients in the active stage were controlled,and serologic CMV IgG turned negative.Moreover,no positive infection was found after 3-month follow-up for those who received foscarnet.At the same time, 3 patients in the control group turned into active infection. Only one receiving foscarnet appeared urine volume cutting down temporarily,and the renal function had a reversible change;2 patients had skin red reaction.Conclusion Foscarnet could control CMV active infection quickly,markedly and firmly.and no recurrence was found during a 3-month follow-up.Foscarnet may protect the inactive patients from turning positive.And foscarnet had no obvious damage to the renal graft function and didn't interfere with the metabolism of blood calcium and cyclosporine A.Foscarnet is a safe and effective drug to treat CMV infection.
