Abstract
Description
technical field
[0001] The invention relates to a biodegradable polymer microsphere loaded with insulin and a preparation method thereof. Background technique
[0002] Diabetes is a worldwide disease, mainly manifested as glucose metabolism disorder caused by endocrine disorders. The incidence of diabetes is increasing year by year, and it has become the third leading cause of death after cardiovascular disease and cancer.
[0003] There are two types of diabetes, one is insulin-dependent diabetes mellitus (IDDM), also known as type 1 diabetes, which mostly appears in children and young adults and can be attributed to a genetic factor or an abnormal immune mechanism As a result, almost no insulin is produced in the body. The other, non-insulin-dependent diabetes mellitus (NIDDM), also known as type 2 diabetes, is diabetes that often begins in middle age. The patient can secrete insulin, but its function cannot be performed normally.
