Example Embodiment

[0028] Example 1

[0029] 1. Material:

[0030] The methods used in this embodiment are conventional methods known to those skilled in the art unless otherwise specified, and the reagents and other materials used, unless otherwise specified, are all commercially available products.

[0031] 2. Method

[0032] 2.1 Preparation of NK cell stock solution

[0033] Step 1: PBMC extraction:

[0034] Centrifuge the fresh blood at 740g for 10 minutes to obtain the upper layer of light yellow plasma and the lower layer of blood cells. Mix the lower layer of blood cells with saline in a volume ratio of 1:1, take a 50ml centrifuge tube, and spread the diluted blood cell suspension on 15ml of lymphocyte separation solution Centrifuge at 400g for 30 minutes. The middle white membranous cell layer was collected, washed with physiological saline, centrifuged at 400g for 10 minutes, the supernatant was discarded, and the washing was repeated once. Finally, resuspend the cell pellet with an appropriate...

Example Embodiment

[0065] Example 2

[0066] This embodiment provides a SNK solution, by weight, the SNK solution is composed of 70.0% of NK cell stock solution, 5.0% of glycerin, 0.03% of ethyl p-hydroxybenzoate, 0.08% of borax, 1.5% of peppermint oil and an appropriate amount of sterile Water composition, wherein the preparation method of the NK cell stock solution is the same as in Example 1.

[0067] Select 3 patients with acne vulgaris and 2 patients with pruritus, spray the above-mentioned SNK liquid directly on the affected area for treatment, use it 2-3 times a day, and count the clinical treatment results.

Abstract

The invention discloses an externally-applied medicine for treating cutaneous appendages and skin pruritic disease and a preparation method and application thereof. The main component of the medicine is an NK cell stock solution which is obtained by amplifying and culturing NK cells. The NK cell stock solution is mixed with different medicine auxiliaries, and an externally-applied liquid preparation or externally-applied paste preparation can be prepared. Compared with the prior art, the externally-applied medicine can be directly used for treating acne, seborrheic dermatitis, pruritus, prurigo nodularis and other cutaneous appendages and skin pruritic disease and is rapid in treatment effect and meanwhile can improve the skin immune system and repair damaged skin according to the characteristics that protein and cell factors secreted by the NK cells can be easily absorbed by skin and can directly act on target cells. Secreted factors in the NK cell stock solution can kill fungi and bacteria, and the medicine achieves the aim of comprehensively treating acne, dermatitis and pruritus, is wide treatment range and can prevent repeated aggravation of pathogenetic conditions.

Description

technical field [0001] The invention relates to the field of biopharmaceuticals, in particular to a medicine for external use for treating skin appendages and pruritus skin diseases, a preparation method and application thereof. Background technique [0002] Acne vulgaris is a very common skin disease with 650 million patients worldwide. It is caused by the blockage of hair follicles and sebaceous glands, which leads to the proliferation of acne bacilli in the skin.
