This study aimed to observe cardiotoxicity induced by three kinds of addictive drugs (i.e., methamphetamine (METH), ketamine (KT), and methadone) in zebrafish embryos. Zebrafish embryos were exposed to various doses of METH, KT, and methadone solutions. The qualitative and quantitative cardiotoxicities were recorded at 24 h and 48 h posttreatment using specific endpoints, i.e., heart rate, heart malformation, pericardial edema, and circulation abnormalities. Results showed that METH at 500 mg/L dose induced a heart rate decline and pericardial edema at 24 h posttreatment, whereas a 1,000 mg/L dose induced significant cardiac malfunctions (i.e., heart rate, pericardial edema, and circulation decrease/absence) at 12 h and 24 h posttreatment compared with the control group. The heart rate of zebrafish embryos treated with KT at 500 mg/L dose decreased compared with the control groups at .. Read More»
