The invention belongs to the technical field of biology, and particularly relates to application of an L-type calcium channel inhibitor in resisting porcine intestinal coronavirus infection. The porcine intestinal coronavirus comprises any one or more of transmissible gastroenteritis virus, porcine epidemic diarrhea virus and porcine D-type coronavirus. The L-type calcium channel inhibitor is prepared from any one or more of verapamil, nicardipine and nimodipine. Research finds that the L-type calcium channel inhibitor such as verapamil can significantly inhibit porcine intestinal coronavirus infection and mainly plays a role within one hour when porcine intestinal coronavirus infection occurs, and it is indicated that the L-type calcium channel inhibitor mainly hinders the invasion process of viruses. The invention develops a brand new field for application of L-type calcium channel inhibitors such as verapamil, and also provides a new direction for research and development of novel anti-porcine intestinal coronavirus drugs.

The invention relates to application of an activating agent in promotion of uranium element discharge. Specifically, the activating agent is prepared from rifampicin, erythromycin, progesterone, aldosterone, bilirubin, cholate vinblastine, doxomicin, adriamycin, paclitaxel, bosentan, ambrisentan, digoxin, verapamil, tonavir, amprenavir, indinavir, hypericum perforatum juice, curcumin, atorvastatin beclomethasone, budesonide, divaricasone carbamazepine and caffeine. And phenytoin. The use dosage of the activating agent is 10 to 60 mg / kg. According to the method, the accumulation amount of uranium in important organs such as bones and kidneys can be remarkably reduced, so that the potential toxic influence on the key organs is reduced.

This invention belongs to the field of biomedical technology, specifically relating to a composition for treating ischemic heart disease and its application. This invention combines two or more of ginsenoside Rg1, ginsenoside Rb1, ginsenoside Re, and notoginsenoside R1, which can significantly downregulate the levels of myocardial enzymes, aspartate aminotransferase (AST), creatine kinase (CK), and lactate dehydrogenase (LDH) in myocardial coronary effusion, with an inhibitory effect significantly higher than that of a single saponin component and the positive control drug verapamil. Simultaneously, the composition exhibits better recovery capabilities for coronary flow (CF), left ventricular developmental pressure (LVDP), maximum rate of decrease in left ventricular pressure (-dp / dtmax), and heart rate (HR) in myocardial coronary effusion. Therefore, the composition can alleviate and treat myocardial ischemia-reperfusion injury through multiple targets and mechanisms, fundamentally inhibiting the development of ischemic heart disease.
