Embodiment 1
[0016] Embodiment 1, the preparation of calf serum deproteinized oral ointment
[0017] To produce 1,000 calf serum deproteinized mouth creams (calf serum deproteinized extract dry powder content: 0.1%, equivalent to calf serum deproteinized extract containing 2.5%), the specific process includes the following steps:
[0018] 1. Preparation of calf serum deproteinized extract dry powder
[0019] Prepare calf serum deproteinized extract dry powder under sterile conditions. The specific method is: take venous blood from Northeast purebred yellow cattle aged 1-6 months, centrifuge at 4000rpm and 4°C for 15 minutes to separate serum; take 5L serum, add 10L of 96% ethanol, stirring constantly, let stand for 60 minutes to denature and precipitate the protein, then centrifuge at 20,000rpm, 4°C for 30min, discard the precipitate, obtain 12.5L of supernatant, use vacuum rotary evaporator, 37°C, 1 atmosphere pressure decompression Remove ethanol; add 1.5g complex protease to the remain...
Embodiment 2
[0024] Embodiment 2, the preparation of calf serum deproteinized oral ointment
[0025] To produce 1,000 calf serum deproteinized mouth creams (calf serum deproteinized extract dry powder content: 0.2%, equivalent to 5% calf serum deproteinized extract), the specific process includes the following steps:
[0026] 1. Preparation of calf serum deproteinized extract dry powder
[0027] Prepare calf serum deproteinized extract dry powder under sterile conditions. The specific method is: take venous blood from Northeast purebred yellow cattle aged 1-6 months, centrifuge at 4000rpm and 4°C for 15 minutes to separate serum; take 5L serum, add 10L of 96% ethanol, stirring constantly, let stand for 60 minutes to denature and precipitate the protein, then centrifuge at 20,000rpm, 4°C for 30min, discard the precipitate, obtain 12.5L of supernatant, use vacuum rotary evaporator, 37°C, 1 atmosphere pressure decompression Remove ethanol; add 1.5g complex protease to the remaining liquid, h...
Embodiment 3
[0032] Embodiment 3, the preparation of calf serum deproteinized oral ointment
[0033] The specific process of producing 1000 calf serum deproteinized oral ointment (calf serum deproteinized extract dry powder content: 0.4%, equivalent to containing calf serum deproteinized extract 10%) includes the following steps:
[0034] 1. Preparation of calf serum deproteinized extract dry powder
[0035] Prepare calf serum deproteinized extract dry powder under sterile conditions. The specific method is: take venous blood from Northeast purebred yellow cattle aged 1-6 months, centrifuge at 4000rpm and 4°C for 15 minutes to separate serum; take 5L serum, add 10L of 96% ethanol, stirring constantly, let stand for 60 minutes to denature and precipitate the protein, then centrifuge at 20,000rpm, 4°C for 30min, discard the precipitate, obtain 12.5L of supernatant, use vacuum rotary evaporator, 37°C, 1 atmosphere pressure decompression Remove ethanol; add 1.5g complex protease to the remain...
