215 results about "Skin immunity" patented technology

Skin immunity is a property of skin that allows it to resist infections from pathogens. In addition to providing a passive physical barrier against infection, the skin also contains elements of the innate and adaptive immune systems which allows it to actively fight infections. Hence the skin provides defense in depth against will infection.

Preparation method of small molecular weight dendrobium candidum polysaccharides

The invention relates to a preparation method of small molecular weight dendrobium candidum polysaccharides. The preparation method comprises following steps: A, bacterial strain activation and expanding culture are carried out, wherein under aseptic conditions, an appropriate amount of a liquid culture medium is used for preparing a fusarium avenaceum bacterium suspension; B, high pressure homogenization is repeated for 5 to 10 times using a high pressure micro jet homogenizer so as to obtain a dendrobium candidum wall-broken homogenate; C, fermentation culturing is carried out, wherein an appropriate amount of a liquid culture medium is injected into a fermentation tank, the dendrobium candidum wall-broken homogenate and the fusarium avenaceum bacterium suspension are weighed, and are delivered into the fermentation tank for fermentation so as to obtain a fermentation liquid; and D, polysaccharide purification is carried out, wherein after fermentation, active carbon is used for decolouring, an obtained product is allowed to stand for 1h for absorption, filtering is carried out so as to remove residue and obtain a filtrate, vacuum pumping filtration is carried out so as to obtain a precipitate, the precipitate is washed with ethanol for three times, and vacuum drying is carried out so as to obtain the small molecular weight dendrobium candidum polysaccharides. The average molecular weight of the small molecular weight dendrobium candidum polysaccharides is lower than 300kDa; and the small molecular weight dendrobium candidum polysaccharides are capable of promoting propagation of skin probiotics, increasing the density of langerhans cells on skin, and improving skin immunity.
