Pharmacokinetics after Periocular Methylprednisolone Sodium Succinate Injection in Rabbit Eyes.

The present study aimed to determine the pharmacokinetics and distribution of methylprednisolone sodium succinate (MPSS) and its metabolic product methylprednisolone (MP) in plasma and ocular tissues after periocular injection of MPSS in rabbit eyes. Forty-eight healthy New Zealand white rabbits were randomly divided into 12 groups, including the control group and 11 MPSS-treated groups sampling at different time points. Rabbits in the MPSS-treated groups underwent left eye periocular injection of MPSS (10 mg).

Apelin-13 attenuates cisplatin-induced cardiotoxicity through inhibition of ROS-mediated DNA damage and regulation of MAPKs and AKT pathways.

Platinum-based chemotherapy represents one of the most effective ways in combating human cancers. However, the cardiotoxicity subsequent severely limited its clinical application. Increased evidences indicate that oxidative stress plays a crucial role in the pathological process of platinum-induced cardiotoxicity.
