A method for manufacturing medicinal fabric that provides enhanced dermatological comfort for the user / patient, especially those with sensitive skin conditions (e.g., acne, contact dermatitis, atopic dermatitis, eczema, psoriasis, rosacea, urticaria, etcetera) including the steps of: (1) selecting a cotton fiber, wherein the cotton fiber is long staple cotton and 100 percent organic; (2) processing the cotton fiber as greige cotton; (3) optionally verifying that the cotton fiber is organic per Global Organic Textile Standards or comparable standards; (4) fermenting or otherwise naturally preparing an herb or plant into a medicinally potent agent / substance and hypoallergenic dyeing agent; (5) using a skin-friendly binding technique, such as binderless dyeing the cotton fiber with the agent / substance via ultrasonic energy or using a technique that similarly uses no irritative chemical binders; (6) selecting a suitable weave type for the specific use / case to reduce mechanical irritation to the user / patient; (7) optionally verifying that the woven cotton fiber has not been contaminated during the manufacturing process through toxicological verification methods; and (8) optionally verifying that the woven cotton fiber passes the standardized dermatological Human Repeat Insult Patch Test.

The invention provides a method for rat or mouse intraperitoneal injection and determining that an injection needle enters the rat or mouse intraperitoneal state. The rat intraperitoneal injection method comprises the steps that a rat is fixed; at the injection position, the injection needle penetrates subcutaneously and penetrates through the abdominal muscle of the mouse to pierce into the abdominal cavity; determining that the injection needle enters an abdominal cavity state. Standardized operation procedures are carried out on a rat or mouse fixing method, injection position determination and judgment on whether an injection needle enters the abdominal cavity state, the success rate of intraperitoneal injection is effectively increased, the mechanical stimulation and bleeding risk of abdominal tissue are reduced, the cecum and small intestine puncture risk is reduced, stress response is reduced, and the safety of intraperitoneal injection is improved. And technical support is provided for drug research and development and disease model construction.

The invention discloses a sustained-release microcapsule and a preparation method thereof as well as a sunscreen lotion and a preparation method thereof, and relates to the technical field of cosmetics, the sustained-release microcapsule comprises the following components in percentage by mass: 82.3%-85.5% of a microcapsule carrier and 14.5%-17.7% of an embedding material, wherein the material of the microcapsule carrier comprises a cross-linking material formed by triethoxy silane polyethylene glycol hydroxyl and dihydroxyl-terminated polysiloxane, and the embedding material comprises lycopene; the sustained-release microcapsule can effectively reduce the degradation rate of lycopene, the embedding rate is high, and the friction coefficient of the sustained-release microcapsule is low, so that the mechanical stimulation to the skin is reduced, and meanwhile, the sustained-release microcapsule has the effect of intelligently and slowly releasing lycopene.
