Abstract

The invention discloses application of silkie melanin extract to preparation of a medicine for preventing and treating parkinson disease. The silkie melanin extract is used as active ingredients of the medicine. The silkie melanin extract can be prepared by a double enzyme hydrolysis method and a method for removing protein by using alkali liquor. The silkie melanin extract can effectively prevent degeneration of dopaminergic neurons during development of parkinson disease, and has the effects of protecting dopaminergic neurons, so the silkie melanin extract can effectively prevent and treat parkinson disease.

Description

Technical field [0001] The invention relates to the medicinal use of a black-bone fowl melanin extract, in particular to the use of the black-bone fowl melanin extract in the preparation of drugs for preventing and treating Parkinson's disease. Background technique [0002] Parkinson's disease (PD), also known as tremor paralysis, is second only to cerebrovascular disease and senile dementia in the elderly. It is clinically manifested as a series of symptoms such as resting tremor, increased muscle tone, slow movement and postural instability. At present, the cause of Parkinson's disease is not yet clear, and it is generally believed that it may be related to factors such as mitochondrial dysfunction, proteolytic stress, immune abnormalities, apoptosis, and genetic factors. The main pathological feature of Parkinson's disease is the degeneration of dopaminergic (DA) nerve cells in the substantia nigra dense zone of the midbrain. The onset of Parkinson's disease is related to ag...
