Embodiment 1

[0038] prescription:

[0039]

[0040] The specific preparation method is:

[0041] Swell the carbomer with an appropriate amount of water for injection, adjust the pH value to form a transparent gel, then sterilize by autoclaving at 121°C, and cool it for later use; dissolve the recombinant bovine basic fibroblast growth factor and human serum albumin in An appropriate amount of water for injection is sterilized by filtration with a 0.22 μm membrane; under sterile conditions, the above-mentioned transparent gel and filtrate are mixed evenly, and then packaged.

Embodiment 2

[0043] prescription:

[0044]

[0045] The specific preparation method is:

[0046] Swell carbomer, hydroxypropyl methylcellulose and appropriate amount of water for injection, adjust the pH value to form a transparent gel, then sterilize by autoclaving at 121°C, cool for later use; grow recombinant bovine basic fibroblasts Factors and human serum albumin are dissolved in an appropriate amount of water for injection, and sterilized by filtration with a 0.22 μm filter membrane; under sterile conditions, the above-mentioned transparent gel and filtrate are mixed evenly, and then packaged.

Embodiment 3

[0048] prescription:

[0049]

[0050] The specific preparation method is:

[0051] Swell hydroxypropyl methylcellulose with appropriate amount of water for injection, adjust the pH value to form a transparent gel, then sterilize by autoclaving at 121°C, cool for later use; mix recombinant bovine basic fibroblast growth factor and human blood Albumin is dissolved in an appropriate amount of water for injection, and sterilized by filtration with a 0.22 μm membrane; under sterile conditions, the above-mentioned transparent gel and filtrate are mixed evenly, and then packaged.

Abstract

Provided are recombination cattle alkaline fibroblast growth factor gel and preparation method of the same. Components and dosage of the gel are as follows: 10000 to 30000 IU of recombination cattle alkaline fibroblast growth factors, 0.5 to 2.5 mg of protein protective agent, 10 to 30 mg of gel matrix, a right amount of pH regulators and 5ml of water for injection. The gel agent is simple in accessory, can reach good stability and releasing effect and is capable of treating various surfaces of wound caused by scalding and trauma.

Description

technical field [0001] The present invention relates to the field of biological products. In particular, it relates to a recombinant bovine basic fibroblast growth factor gel and a preparation method thereof. Background technique [0002] The skin is an important barrier for the body to avoid infection and dehydration. Severe trauma, burns, and skin ulcers caused by certain diseases such as diabetes can have a huge physical and mental impact on patients. Therefore, the repair of skin wounds is a problem of great concern in the field of medicine. [0003] Since the end of last century, various studies have been carried out on the post-traumatic tissue repair process, mechanism and treatment. The level has been continuously improved. At present, a variety of genes promoting granulation tissue growth, vascularization and re-epithelialization have been constructed, such as epidermal cytokine, basic fibroblast growth factor and transforming growth factor. [0004] It has been...
