Abstract
AIM
To observe the concentration of circulating ADM and its side effects by hepatic artery infusion of Adriamycin(ADM) combined with hemoperfusion (HP).
METHODS
ADM was infused through the dogs hepatic artery. At the same time, the femoral artery and femoral vein catheters were inserted and HP(NK-107 resin (HPI) and Japanese activated charcoal(HP II) as adsorbents) was performed. The concentration of circulating blood ADM was determined and blood routine, myocardiac enzymes, liver and kidney function were observed.
RESULTS
The plasma concentration of ADM at 1 h, 2 h; 3 d and 14 d in HP I, II groups (89±9, 60±15, 21±5, 10±2; 99±14, 61±13, 26±5, 12±2 mg.l-1) were decreased apparently as compared with the control group (312±23, 237±12, 116±15, 58±8 mg.l-1) (P<0.01). After HP 24 h (0.9±0.4, 11.9±6.4, 1.0±0.3; 1.1±0.3, 4.3±3.7, 1.9±0.6 μkat.l-1) and 72 h (0.9±0.4, 8.2±4.5, 0.8±0.3; 1.1±0.1, 2.6±2.3, 2.7±2.3 μkat.l-1), myocardiac enzymes (LDH, CPK-MB, α-HBDH) had no change (P>0.05). But in control group, after HP 24 h (1.6±0.2, 23.9±12.9, 2.7±0.3 μkat.l-1), they began to increase (P<0.05) and increased markedly after 72 h (3.1±0.1, 33.7±10.4, 8.5±0.3 μkat.l-1) (P<0.01) as compared with before HP (0.8±0.1, 11.1±10.7, 1.4±0.1 μkat.l-1). Before and after HP, the peripheral WBC, RBC, Hb and Pt at 3, 7 and 14 d had no significant change (P >0.05). But in the control group WBC, Pt, RBC and Hb were lower than before (16.3±4.2×109/L, 131±38×109/L, 5.9±1.6×1012/L, 131±28 g/L) at 7 d (8.5±5.4×109/L, 77±35×109/L, 4.8±1.2×1012/L, 94±27 g/L) (P<0.05) and much lower than before at 14 d (6.2±4.4×109/L, 69±39×109/L, 5.2±1.6×1012/L, 109±28 g/L P<0.01). Before and after HP, no obvious changes were found in liver function (ALT, AST and TBil) and kidney function (BUN and Cr) (P>0.05).
CONCLUSION
ADM hepatic artery infusion combined with HP, using NK-107 resin and Japanese activated charcoal as adsorbents, can decrease the concentration of circulating blood ADM and its side effects.
