AIM:To study the effect of remifentanil on monophasic action potential and transmural dispersion of repolarization (TDR) in the 3-layer myocardium of isolated rabbit hearts .METHODS:Adult rabbits (n=18, 2.0 ~2.5 kg) were used to isolate the hearts for preparing Langendorff perfusion model .The hearts were randomly divided into 3 groups after perfusion with K-H solution for 15 min: the perfusion in control group ( C group ) continued for 60 min; the hearts in remifentanil group ( R group ) were perfused with 12 μg/L remifentanil K-H solution for 60 min; the hearts in remifentanil+aminophylline group ( RA group ) were given 60-min perfusion of 12 μg/L K-H remifentanil +30 mg/L aminophylline .The HR and 3 layers of myocardial monophasic action potential ( MAP) in the left ventricular anterior wall were recorded at time points after balanced infusion for 15 min ( T0 ) , and continued perfusion for 15 min ( T1 ) , 30 min ( T2 ) and 60 min ( T3 ) .The monophasic action potential duration of repolarization at 90%( MAPD90 ) and the transmural dispersion of repolarization (TDR) were calculated.The early afterdepolarization, delay afterdepolarization and arrhythmia were also observed.RESULTS:In R group, slower HR and prolonger MAPD90 and TDR at T1 ~T3 were observed as com-pared with those at T0(P<0.05).R group showed slower HR and longer MAPD 90 and TDR than C group and RA group (P<0.05).CONCLUSION:Remifentanil slows the HR, extends the MAPD90 and increases the TDR, thus being prone to induce reentry.Aminophylline makes HR faster and MAPD90 shorter, thereby reducing the TDR.

Objective To evaluate the effect of aminophylline on monophasic action potential (MAP) during remifentanil-induced negative chronotropic effect in the isolated rabbit hearts.Methods Eighteen healthy adult rabbits,weighing 2.0-2.5 kg,wereused in the study.Their hearts were excised and retrogradely perfused in a Langendorff apparatus.After 15 min of stabilization with K-H solution,the isolated hearts were randomly divided into 3 groups (n =6 each) using a random number table:control group (group C),remifentanil group (R group),and remifentanil + aminophylline group (RA group).Group C was perfused with 37 ℃ K-H solution for 60 min.Group R was perfused with K-H solution containing remifentanil 12 ng/ml for 60 min.Group RA was perfused with K-H solution containing remifentanil 12 ng/ml and aminophylline 30 μg/ml for 60 min.At 15 min of stabilization and 15,30 and 60 min of perfusion,HR and MAP in the myardium of left ventricle were recorded:MAP duration at 90％ and 50％ repolarization (MAPD90,MAPD50) was calculated.The early after depolarization,delay after depolarization and arrhythmia were recorded.Results Compared with group C,HR was significantly decreased at 15,30 and 60 min of perfusion,and MAPD50 and MAPD90 were prolonged in goup R,and HR was increased in group RA.HR was significantly higher,and MAPD50 and MAPD90 were shorter in RA group than in group R.No early after depolarization,delay after depolarization or arrhythmia developed in each group.Conclusion Aminophylline antagonizes remifentanil-induced negative chronotropic effect through shortening monophasic action potential duration in the myocardium of left ventricle of the isolated rabbit hearts.

Objective: To explore the bidirectional solid fermentation transformation of 25 different edible fungal strains with Isatidis Radix (IR) and Isatidis Folium (IF) to get the synergism antibacterial effect of fermentation substance. Methods: The dominant strains grown on IR and IF were obtained through initial screening and repeated screening.

Objective To study the effects of dexmedetomidine on the monophasic action po-tential duration and the transmural dispersion of repolarization during ischemia-reperfusion of isolated rabbit hearts and thus explore its effect on myocardial ischemia-reperfusion electrophysiological char-acteristics.Methods Eighteen healthy adult rabbits,weighing (2.0±0.5)kg,were randomly divided into 3 groups after successful preparation of Langendorff isolated heart perfusion model and 1 5 min perfusion and balance of K-H fluid.In the control group (group C),37 ℃ K-H fluid was continuously perfused and balanced for 1 50 min.In the ischemia/reperfusion group (group IR),K-H fluid was stopped after continuous perfusion and balance for 1 5 min and cardiac arrest was induced for 60 min with the injection of Thomas solution (4 ℃,10 ml/kg)while the heart was protected by the low tem-perature Thomas solution (4 ℃)around it.Reperfusion of Thomas solution (4 ℃,5 ml/kg)was performed for 30 min and the heart was resuscitated by the perfusion of K-H fluid for 60 min.In dexmedetomidine group (group DEX),dexmedetomidine (25 ng/ml)was added in the K-H fluid and the Thomas solution.Other procedures were same as in group IR.Heart rate(HR),monophasic ac-tion potential amplitude (MAPA)of the three layers of heart [endocardium (Endo),myocardium (Mid)and epicardium (Epi)],0 phase maximal increase rate (Vmax),90% monophasic action po-tential duration (MAPD90 )and transmural dispersion of repolarization (TDR)were recorded at the time of continuous balance perfusion 1 5 min(T0 ),continuous perfusion 1 5 min/balance 30 min(T1 ), reperfusion 30 min/balance 120 min(T2 )and reperfusion 60 min/balance 1 50 min(T3 ).Cardiac ar-rhythmia and resuscitation time at cardiac reperfusion were observed,without using drugs to restore normal cardiac rhythm.Results In group DEX,cardiac resuscitation time was significantly shorter (1 6.67±3.78)s than that in group IR (46.33±7.29)s (P <0.05);At T2 ,in group IR,arrhythmia was seen in 6 rabbits and normal cardiac rhythm was restored within 2 min in two rabbits,while in group DEX,arrhythmia was seen in 2 rabbits and normal cardiac rhythm was restored within 2 min in one rabbit,without the use of any drugs.When compared with T0 ,HR was slower at T2 and T3 in group IR and at T1-T3 in group DEX (P <0.05);Compared with T1 ,HR was slower at T2 and T3 in group DEX (P <0.05);Compared with T2 and group C,HR was slower at T3 in group DEX;At T1-T3 ,HR in group DEX were significantly slower than that in group IR (P <0.05).Compared with T0 ,MAPD90 of Mid at T1 and Epi,Mid,Endo at T2 and T3 in group DEX were significantly extend-ed (P <0.05);Compared with T1 ,MAPD90 of Epi,Mid,Endo in group DEX were significantly ex-tended at T3 ;MAPD90 of Mid in group DEX was significantly longer than that in group C at T3 (P <0.05);At T2 and T3 ,MAPD90 of Epi,Mid,Endo in group DEX were longer than that in group IR (P <0.05).Compared with T0 and group C,TDR at T2 and T3 in group IR and at T1-T3 in group DEX significantly increased (P <0.05),while TDR in group DEX were less than that in group IR at T2 and T3 (P <0.05).Conclusion Dexmedetomidine appeared to prolong MAPD and restrain the dis-proportion of resuscitation of myocardial ischemia-reperfusion injury.Dexmedetomidine could have the effect of stabilizing myocardial ischemia-reperfusion electrophysiological characteristics.

Objective To investigate the effects of hypothermia combined with dexmedetomidine on myocardial monophasic action potentials (MAPs) in isolated rabbit hearts.Methods Adult rabbits,weighing 2.0-2.5 kg,were heparinized and anesthetized with pentobarbital sodium 30 mg/kg.Their hearts were rapidly removed and retrogradely perfused in a Langendorff apparatus at 37 ℃.Eighteen hearts were randomly divided into 3 groups (n =6 each) using a random number table:control group (group C),hypothermia group (group H),and hypothermia+dexmedetomidine group (group HD).The hearts were continuously perfused for 60 min with 37 ℃ K-H solution in group C,with 32 ℃ K-H solution in group H,or with 32 ℃ K-H solution containing dexmedetomidine 25 ng/ml in group HD.At the end of equilibration (T0) and at 15,30 and 60 min of perfusion with K-H solution,HR and MAPs of left ventricular epicardium,mid-myocardium and endocardium were recorded.MAP duration at 50％ repolarization (MAPD50) and at 90％ repolarization (MAPD90),monophasic action potential amplitude (MAPA) and maximal velocity (Vmax) were calculated.Results Compared with group C,HR was significantly decreased,and MAPD50 and MAPD90 were prolonged at each time of perfusion with K-H solution in H and HD groups.There was no significant difference in HR,MAPD50 and MAPD90 between H group and HD group.There was no significant difference in MAPA and Vmax between the three groups.Conclusion Hypothermia combined with dexmedetomidine can lead to prolongation of myocardial repolarization,and dexmedetomidine exerts no effect on hypothermia-induced change in MAPs in isolated rabbit hearts.
