Problems solved by technology

[0005] At present, the preparation methods of oral protein pharmaceutical preparations are mostly freeze-dried, and there are many problems: how to ensure stability, how to eliminate the bad taste and reduce the patient's compliance, so as to prepare an oral protein that does not affect its activity and is easy to be accepted by patients. protein preparation

Embodiment 1

[0076] Embodiment 1: Preparation of earthworm active protein

[0077] Take fresh earthworms and wash them repeatedly in water, drain their digestive tract dirt, wash them, weigh them, add 2 times the amount of 20mM phosphate buffer with a pH value of 6.8, and mash them in a tissue grinder to make Homogenize, extract at room temperature for 4-6 hours, centrifuge at 4°C for 20 minutes at high speed, take the supernatant, slowly add the ground ammonium sulfate solid at 4°C, and stir while adding, so that the saturation of ammonium sulfate reaches 80 %, place overnight at 4°C, centrifuge at 4°C for 10 minutes at high speed, take the precipitate, suspend the precipitate with 20mM phosphate buffer saline with a pH value of 6.8, and put it in a dialysis bag with a molecular weight of 3500 for 20mM phosphate buffer with a pH value of 6.8 Dialyze for 48 hours, change the medium 4-5 times in the middle, centrifuge the obtained protein solution at 4°C for 20 minutes at high speed, and th...

Embodiment 2

[0078] Example 2: Preparation of Dilong Active Protein Oral Containing Instant Preparation

[0079] Add 5‰ aspartame, 10% pineapple essence, and 10% deodorizing essence to earthworm active protein, stir evenly, and freeze-dry according to the following steps:

[0080] Step 1: The heating rate is 2.1°C / min, the sample temperature is -30°C, and the freeze-drying time is 0.5 hours;

[0081] Step 2: The heating rate is 1.16°C / min, the sample temperature is 0°C, and the freeze-drying time is 6.0 hours;

[0082] Step 3: The heating rate is 1.01°C / min, the sample temperature is 5°C, and the freeze-drying time is 10.0 hours;

[0083] Step 4: The heating rate is 1.16°C / min, the sample temperature is 20°C, and the freeze-drying time is 20.0 hours.

Embodiment 3

[0084] Example 3: Research on the antiasthmatic effect of earthworm active protein

[0085] 1. Modeling method

[0086] Ovalbumin (III grade) was dissolved in physiological saline to prepare 5% ovalbumin physiological saline solution. Each guinea pig was injected intramuscularly with 0.5 ml and intraperitoneally with 1 ml in both hind legs. After 2 weeks, the sensitized guinea pig was placed in an airtight glass bell jar and stimulated with 0.1% ovalbumin atomization.

[0087] 2. Grouping and dosage

[0088] 40 guinea pigs, half ♀♂, were randomly divided into 5 groups, 8 in each group, the five groups were: blank group, positive drug (montelukast sodium tablets) control group, high, middle and low administration concentration group. The concentration is set to be 0.12g / kg of fresh Dilong antiasthma active protein as the middle concentration, and then rise and fall to 0.06g / kg and 0.24g / kg respectively. The dosage was set at 10ml / kg. The preparation of protein solutions wi...

Abstract

The invention relates to an animal protein medicament buccal instant preparation, and particularly discloses an earthworm protein-containing buccal instant preparation and a preparation method thereof. The preparation consists of 75 weight percent of earthworm protein extract and 25 weight percent of composite flavoring agent, wherein the protein content of the earthworm protein extract is more than 50 percent. In addition, the invention also discloses the preparation method and application of the preparation. The preparation has the obvious antiasthmatic effect, and can effectively inhibit asthma reaction caused by antigen attack of eggalbumin sensitized guinea pigs; and the action mechanism of the preparation is possibly related to anti-leukotriene effect through preliminary analysis of isolated trachea smooth muscle.

Description

technical field [0001] The invention relates to an oral instant preparation of animal protein drugs and a preparation method thereof, in particular to an oral instant preparation of earthworm protein and a preparation method thereof. In addition, the present invention also relates to the application of the preparation. Background technique [0002] The name of the earthworm medicine is Dilong, and its medicinal use is first recorded in "The Book of Songs", and "Shen Nong's Herbal Classic" is listed as a lower grade. The traditional Chinese medicine Dilong has the effects of clearing away heat and calming convulsions, dredging collaterals, relieving asthma and diuresis, and is a commonly used animal medicinal material. The earthworms recorded in the Chinese Pharmacopoeia 2005 edition are Pheretima aspergillum (E.Perrier), Pheretimavulagris Chen, Pheretima guillelm (Michaelsen) or Pheretimaectinifera Michaelsen. dry body. In addition to the species recorded in the Pharmacop...
