1.. An enzyme derived from the testes of mammals that hydrolyze glass polysaccharides, a white or yellowish powder, soluble in water and insoluble in ethanol, acetone, or ether. Odorless. Stability is good, 420C continuous heating, 60min vitality without loss, 1000C continuous heating 5 min, vitality can be retained 80%. It is easy to inactivate in low concentration aqueous solution and can be protected against inactivation by gelatin or Arabia gum. Fe2+ and Cu2+ ions have reversible inhibitory effects on enzymes. Pb2+, Hg2+, Ni, 2+ and plasma have no obvious effect on enzyme activity. In the presence of sodium chloride (0.15mol/L) or protamine sulfate, the inhibitory effect of chondroitin sulfate, B (heparin), heparan sulfate, heparan sulfate, heparin sodium, and high concentration of hyaluronic acid on the inhibition of hyaluronidase could be reversed.
Hyaluronic acid enzyme injection is glass acid enzyme plus proper excipient, and the freeze-dried aseptic product is white or white like freeze-dried lump or powder. The aqueous solution is unstable and should be prepared before use.

1. glass acid enzyme can be used as egg splitting enzyme. It can be used to accelerate the absorption of muscle and subcutaneous injection of liquid medicine, reduce the pain of injection site, promote the infiltration of local anesthetic, and promote the local edema or hematoma dispersion after operation and trauma. It can also be used for intestinal adhesion. But salicylic acid inhibits the action of hyaluronidase. Intravenous injection. Try skin test before use so as to avoid allergic reaction. Infection and sore sites are forbidden to prevent proliferation. The mice were subcutaneously injected with LD50>25 million units of /kg; the mice were injected with LD50>1.25 million units of /kg.
Subcutaneous or intramuscular injection, 150 ~ 1500U/, 1, 1 ~ 2 times, first with saline injection or dissolved in water, and then mixed with other injections; subcutaneous infusion, infusion plus the product 150U 100ml.
This product is an antihypertensive drug. Mice orally took LC50 as 122ml/kg, and LD50 in rats was 90ml/kg

2-8 C airtight, cool and dry place

Acute toxicity:
The mice were orally treated with LC50 as 122ml/kg
The rat LD50 was 90ml/kg
The mice were injected with LD50>25 million units /kg;
The mice were injected with LD50>1.25 million units of /kg. Subcutaneous or intramuscular injection, 150 ~ 1500U/, 1, 1 ~ 2 times, first with saline injection or dissolved in water, and then mixed with other injections; subcutaneous infusion, infusion plus the product 150U 100ml.

The substance may be hazardous to the environment, and particular attention should be paid to the body of water.
