Embodiment 1
[0045] Prepare raw materials according to weight ratio as follows:
[0046] Pituitary adrenal cortex extract 8mg×1000
[0047] Reduced glutathione 1.2mg×1000
[0048] Lecithin or soybean lecithin 9.8mg×1000
[0049] Cholesterol 9mg×1000
[0050] Phosphate buffer solution of 0.01mol / L, pH value 2.5-3.0 2000mg×1000
[0051] Packed into 1000 sticks
[0052] Production operation:
[0053] (1) Dissolve 9800mg of lecithin or soybean lecithin with 30ml-50ml of absolute ethanol (analytically pure), and add dropwise to about 1200ml of phosphate buffer solution with a pH of 2.5-3.0 and a concentration of 0.01mol / L under stirring In the process, stir the mixture evenly, and distill under reduced pressure at 60°C±5°C until the ethanol evaporates completely.
[0054] (2) Put the liquid obtained in step 1 into a tissue pounder and stir for 5-10 minutes, then steam sterilize at 115°C-121°C for 15 minutes. Ultrasonic stirring was performed twice, each time for 10 minutes.
