Abstract

The invention discloses a minipig chronic pulmonary hypertension animal model. A monocrotaline solution is injected to an abdominal cavity of a male or female healthy minipig which is 1-5 months old and is 3-15kg in weight; and the minipig chronic pulmonary hypertension animal model is obtained after the monocrotaline solution is injected for 4-9 weeks. Correspondingly, the invention discloses a construction method of the minipig chronic pulmonary hypertension animal model. With the adoption of the minipig chronic pulmonary hypertension animal model and the construction method thereof, the body size and structure of the minipig adopted by the minipig chronic pulmonary hypertension animal model are similar to the body size and structure of a human body, so that the minipig chronic pulmonary hypertension animal model can be determined and observed in clinic by clinical equipment; and pathological changes of the minipig chronic pulmonary hypertension animal model approach to clinical pathological changes of human beings, thus being beneficial for observation, treatment and research for a long time.

Description

technical field [0001] The invention relates to the field of animal models of chronic pulmonary hypertension, in particular to a miniature pig animal model of chronic pulmonary hypertension and a construction method thereof. Background technique [0002] Pulmonary hypertension (Pulmonary Hypertension, PH) is one of the major cardiopulmonary vascular diseases in humans. The establishment of PH animal model is a platform for basic and clinical research on the disease. Currently, animal models of PH are divided into two types: acute and chronic. The establishment of acute animal models is mainly based on hypoxic or / and hypobaric hypoxic PH animal models, and rats are more commonly used (Chen Liyan et al. Resveratrol glycosides on phospholipase A_2 in chronic normobaric hypoxic pulmonary hypertension model , nitric oxide and endothelin levels. Chinese Journal of Pathophysiology 2006), followed by experimental animals such as mice and rabbits. [0003] The establishment of chr...
