Abstract

The invention provides an eye drop, which comprises an effective treatment amount of deproteinized calf blood extractive, chitosan and water. The eye drop of the invention is stable and can be used for curing keratonosus, conjunctival lesion and dry eye syndrome.

Description

Technical field: [0001] The invention relates to an eye drop containing calf blood deproteinized extract. Background technique: [0002] Calf blood deproteinized extract is a biological preparation researched and invented by German scholar Professor Jaeger. It is made from the blood of healthy and vigorously developed calves within six months of birth, and the molecular weight is less than 6000, which is made by membrane filtration technology. Deproteinized blood extract. This deproteinized blood extract contains electrolytes, trace essential elements, nucleic acid derivatives, amino acids, oligosaccharides, low-molecular-weight polypeptides, glycolipids, and intermediate products of lipid metabolism. Calf blood protein-free extract can promote the uptake and utilization of glucose and oxygen by cell mitochondria at the cellular level (independent of insulin), increase ATP synthesis, increase cell energy, and activate various enzyme activities. In the case of low blood oxy...
