Problems solved by technology

Because the Philippine leech is not easy to grow in cold areas, and it is not easy to raise it, there is no documented record of raising the Philippine leech
[0007] In terms of the extraction of hirudin, there are many methods for hirudin at

Embodiment 1

[0022] Embodiment 1, will capture strong and robust Hirudo phenanthae in the wild, put on small pool (generally every 4-8 square meters is good) by size and carry out meticulous feeding and cooking, every cubic meter of water can put finished product 600-1500 In the breeding process, flowing water and oxygenation measures can be used. The food to be fed includes fresh cow blood, pig blood, sheep blood, etc. with sodium salts, the sodium salts include sodium acetate, sodium phosphate, lemon sodium arginine, sodium lysine, sodium ascorbate, sodium cystine, mainly to prevent blood coagulation, put the uncoagulated blood on a dish containing sponge during feeding, and then put the dish on Go to the foam board floating in the water of the breeding pond, and at the same time stir the water to attract the leeches to feed. When breeding, it is mated with the robust Hirudo phenanthae that introduces excellent provenance.

Embodiment 2

[0023]Embodiment 2, introduces the robust Hirudo phenanthae of fine provenance, puts in small pool (generally every 4-8 square meters is good) by size and carries out meticulous feeding and cooking, and every cubic meter of water can put finished product 600-1500 In the breeding process, flowing water and oxygenation measures can be used. The food to be fed includes fresh cow blood, pig blood, sheep blood, etc. obtained by treating with 0.05-0.2% sodium salt. The sodium salt includes acetic acid Sodium, sodium phosphate, sodium citrate, sodium arginine, sodium lysine, sodium ascorbate, sodium cystine, mainly to prevent blood coagulation, packed with bovine small intestine, pig small intestine or artificial casing, and then wrapped with thin wire The small intestines are bundled into nodules of 2-3 cm each to prevent them from entering the breeding water for feeding. When breeding, use the wild to catch the strong pheasant to mate with it.

Abstract

This invention provides a method for culturing a fluke. Culture introduced elite or wild strong flukes by manpower in clean pool or tank. The culturing process is feeding breeding seedling and feeding seedling in a small pool with anticoagulant-treated fresh blood of cattle, pig, sheep or fowls, or feeding with the packaged treated fresh blood packaged with pig small intestine and put in the pool after bundled to nodular of 2-3cm each membered. This feeding technology is modern; especially this invention adopts noncondensing blood that can guarantee both quality and novelty of the blood, so as to guarantee health and good growing of flukes.

Description

technical field [0001] The invention relates to an artificial cultivation method of medical leeches, in particular to an artificial cultivation method of the leeches phenanthrene. Background technique [0002] Hirudin is an anticoagulant substance extracted from blood-sucking leeches (leeches). Leeches were first recorded in my country's "Shen Nong's Materia Medica", and later in monographs such as "Compendium of Materia Medica" and "Chinese Animal Medicine". In 1884, Haycraft discovered that the leech extract had anticoagulant effect. In 1955, MarkwMdt pointed out that the anticoagulant substance was a protein and named it hirudin. After 1986, genetically recombined hirudin came out, which was the in-depth research and clinical practice of hirudin. Applications open up vast prospects. According to literature records, natural hirudin is a low-molecular-weight polypeptide composed of 65 amino acids, and its functions have the following aspects: 1. It has anticoagulant effec...
