Problems solved by technology

Some drugs can be injected directly into the brain or the eye, but for chronic diseases or special conditions that require long-term treatment, this method is really difficult to implement, which is why proteins are difficult to use in eye treatments.

Embodiment 1

[0033] (1) Preparation of medium:

[0034] Preparation of pig heart extract: take fresh pig heart, remove blood clots, fat and fascia, wash it with water, crush it, weigh it, add twice the amount of water for injection, store it at 4°C for 14 hours, take it out, and boil it for two hours. Heat and filter with eight layers of gauze, and then use a Buchner funnel to suction filter to obtain a clear yellow liquid for later use.

[0035] Preparation of pig heart peptone medium: Weigh 2 g of peptone and 0.9 g of sodium chloride, measure 20 ml of pig heart extract, add water for injection to 100 ml, heat to dissolve, stir evenly, and sterilize to prepare pig heart peptone medium for later use.

[0036] (2) Preparation of Staphylococcus aureus yellow subspecies seed solution:

[0037] After opening the strain of Staphylococcus aureus subsp. yellow, transfer it to the pig heart peptone medium, cultivate it at 36°C±1°C for 24 hours, then transfer it to the nutrient agar plate, divide ...

Abstract

A process for preparing the eye drops used to prevent and suppress senile macular degeneration includes such steps as revival of Staphylococcus aureus, preparing the seed culturing liquid and fermenting culture bacterium liquid in hog heart pepton as culture medium, proportionally mixing cultured bacterial liquid, sodium chloride and the water for injection, filtering and sterilizing.

Description

(1) Technical field: [0001] The invention relates to a method for preparing Yandikang eye drops for preventing and inhibiting age-related macular degeneration by using metabolites of Staphylococcus aureus subsp. , has a regulating effect on the ciliary muscle, and can also improve eye microcirculation. (two) background technology: [0002] Age-related macular degeneration (AMD) is also known as age-related macular degeneration or aging macular degeneration. Most of them start around the age of 50, and the older the age, the higher the incidence rate. The incidence has no obvious relationship with gender and race. Both eyes are affected simultaneously or successively. Due to different clinical manifestations, it can be divided into two types: atrophic (dry) and exudative (wet). The former is more common, while the latter is only 1 / 15 to 1 / 10 of the former. Black dots or dark shadows appear, visual fatigue, difficulty in reading, severe impact on vision in the middle and l...
