Problems solved by technology

[0004] Cordycepin has biological activities such as anti-tumor, anti-virus, anti-fungal, and immune regulation. The main mechanism of action is to replace adenosine and participate in cell metabolism, inhibit mRNA tailing, and cordycepin 5'triphosphate is connected to the 3' end of mRNA. Due to the lack of 3'-OH, the mRNA cannot be extended, and the mRNA cannot be matured, which ultimately inhibits the growth of tumor cells or pathogenic cells
[0005] At present, there is no report on the application of the Acremonium acremonium culture to prepare the medicine for relieving visual fatigue.

Abstract

The invention belongs to the technical field of biological medicines and in particular relates to an acremonium terricola culture and application thereof. The acremonium terricola culture provided by the invention can effectively alleviate visual fatigue symptoms such as eye distension, sore eyes, photophobia, blurred vision, dry eyes and fading eyesight. The acremonium terricola culture provided by the invention is low in production cost, can be easily obtained in large scale and can be applied in preparation of medicines for relieving visual fatigue conveniently.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a culture of acremonium acremonium and its application. Background technique [0002] Visual fatigue is a common disease in ophthalmology at present. The symptoms of patients are various. The common ones are short-distance work cannot last long, pain in the eyes and around the eyes, blurred vision, dry eyes, tears, etc. In severe cases, headache, nausea, dizziness. It is not an independent disease, but a group of fatigue syndromes caused by various reasons. The reasons for its occurrence are also various, and the common ones are: (1) The reasons of the eye itself, such as myopia, hyperopia, astigmatism and other refractive errors, adjustment factors, eye muscle factors, conjunctivitis, keratitis, inappropriate glasses etc.; (2) Systemic factors, such as neurasthenia, physical fatigue, hysteria or menopausal women; (3) Environmental factors, such as insufficient ...
