Abstract

The invention relates to the field of medicine technology and provides an injection for curing ischemic-reperfusion damage of brain, heart, kidney and other tissue organs. The preparation method includes placing a medical injection flexible bag under low pressure for degasification, carrying out low-temperature pretreatment after air extraction, then injecting hydrogen for pressurized dissolution and dissolving hydrogen in the injection and storing under constant pressure and about 4 DEG C for standby. The injection can be used after 24-hour stabilization. The animal experiment proves that the injection of the invention can reduce focal cerebral ischemic-reperfusion damage in rats, neuron injuries and apoptosis number, decrease the activity of apoptosis enzyme in pallium and hippocampus, reduce the ischemic-reperfusion damage extent of heart and kidney and protect the function of ischemic-reperfusion heart and kidney. The hydrogen-included injection can be used as the medicine for curing the ischemic-reperfusion damages of brain, heart, kidney and other important organs.

Description

technical field [0001] The invention relates to the technical field of medicine, and is a hydrogen-containing injection that can be used for treating ischemia-reperfusion injury. Background technique [0002] Ischemia is one of the common causes of clinical diseases. Ischemic diseases can usually be treated by early measures such as thrombolysis and anti-free radical damage, but secondary ischemia-reperfusion injury may occur, which is an important pathophysiological process of diseases such as cerebral infarction. In the field of medical technology, hydrogen has been used in the treatment of saturation diving and decompression sickness. So far, there are no relevant reports on the use of hydrogen-containing injections to prevent and treat ischemia-reperfusion injury. Contents of the invention [0003] The invention provides a hydrogen-containing injection, which can be used for treating tissue damage and organ dysfunction caused by ischemia-reperfusion. [0004] The pr...
