| description | <b>Aim:</b> Doxorubicin (DOX) is used to treat various human cancers, but
its use is limited due to its cardiotoxicity and heart failure effects. Pimobendan
(PIMO) is used to treat heart failure. Although PIMO has
been reported to suppress proinflammatory cytokines no studies have
investigated the effect of PIMO on antiinflammatory cytokines in cardiotoxicity.
The purpose of this study was to determine the effects of
PIMO on tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6 and
IL-10 in the DOX-induced cardiotoxicity.<p>
<b>Materials and Methods:</b> The 54 male Swiss mice were categorized as
Control (n:6), DOX (n:24), and DOX+PIMO (n:24). The Control group
received physiological saline solution intraperitoneally (IP) and gavage.
DOX group received a single IP injection of 18 mg/kg DOX, and
DOX+PIMO group received a single IP injection of 18 mg/kg DOX + 1
mg/kg PIMO SID for 5 days by gavage. Blood samples were collected
from the heart by cardiac puncture under general anesthesia at 2, 24,
72 and 120 h following DOX administration. Cytokines levels were measured
using ELISA.<p>
<b>Results:</b> This study showed an increase in proinflammatory cytokines
and a decrease in antiinflammatory cytokines, dependent on DOXinduced
cardiotoxicity. PIMO administration did not prevent TNF-α
and IL-6 increase or IL-10 decrease. Previous studies have focused on
the effect of PIMO on proinflammatory cytokines in cardiotoxicity, but
no study has evaluated the effect of PIMO on IL-10 level. Interestingly,
in the present study, PIMO did not increase IL-10 levels.<p>
<b>Conclusion: </b>It may be stated that PIMO has no protective affect against
DOX-induced cardiotoxicity. |
