Abstract

The invention belongs to the technical field of medicines and discloses a Lugua polypeptide injection. According to a preparing method of the injection, a preparing method of a deer bone extract liquid includes adding composite enzymes into deer bone, extracting the deer bone with high-temperature water, adjusting the pH value with an acid, heating, allowing the mixture to stand at 20-30 DEG C, concentrating, allowing the concentrate to stand at 20-30 DEG C, adjusting the pH value with an alkali, concentrating, allowing the concentrate to stand at 20-30 DEG C, adjusting the pH value with an acid, performing gradient ultrafiltration, and storing at a low temperature to obtain the deer bone extract liquid; a preparing method of a muskmelon seed extract liquid includes extracting muskmelon seeds with high-temperature water, adjusting the pH value with an acid, allowing the mixture to stand at 20-30 DEG C, concentrating, centrifuging, performing ultrafiltration, adjusting the pH value with an alkali, freezing and storing with gradient temperatures, unfreezing, concentrating, centrifuging, adjusting the pH value with an acid, performing gradient ultrafiltration, and storing at a low temperature to obtain the muskmelon seed extract liquid; and the deer bone extract liquid and the muskmelon seed extract liquid are mixed, subjected to ultrafiltration and prepared into the injection.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an injection preparation of lugua polypeptide. Background technique [0002] The pharmaceutical preparations made from deer bones and melon seeds are mainly deer melon polypeptide injection preparations, which can regulate bone metabolism, stimulate osteoblast proliferation, and promote new bone formation, and can also regulate calcium scale metabolism and increase bone calcium deposition , prevent osteoporosis, and has anti-inflammatory, analgesic, anti-rheumatic effects, and has been widely used clinically. Clinical application shows that the injection preparation made of deer bone and melon seeds is an effective drug for the treatment of nonunion of fracture, osteoporosis, rheumatism, rheumatoid arthritis, avascular necrosis of scaphoid bone and soft tissue injury, etc. The application prospect of orthopedics is broad.
