Abstract

The invention discloses a mesoporous lime-silicate xerogel, which contains silicon oxide, or silicon oxide and calcium oxide. In the power X-ray diffraction (XRD) pattern, 1 to 3 peaks are between 0 to 2 degrees on the abscissa 2 theta and holes of the mesoporous lime-silicate xerogel are orderly arranged. The invention also discloses the preparation method and the application in preparing drugs or materials for curing skin ulcer. The mesoporous lime-silicate xerogel of the invention, with even aperture size, high porousness, even arrangement of holes and good hole appearance, can effectivelypromote the healing of ulcer in a simple use method and can cure skin ulcer by compounding with drugs or growth factors. Te mesoporous lime-silicate xerogel can be used for curing skin ulcer on different medical occasions, such as cervical erosion, diabetic ulcer, wound surface due to operation and trauma, bedsore, stress ulcer, skin and mucosal ulcer, erosive lesion, local II or III burn and scald wound, wound difficult to heal, etc.

Description

technical field

[0001] The invention relates to a xerogel and its preparation method and application, in particular to a mesoporous calcium silica xerogel and its preparation method and application. Background technique

[0002] Skin ulcer refers to a class of diseases caused by different causes of body surface tissue necrosis, ulceration, and defect. Skin ulcer is a disease characterized by ulcerative lesions of the skin and mucous membranes. During the course of the disease, there are pathological changes such as wound exudation, infection, and erosion, as well as skin and mucous membrane ulceration and soft tissue damage, and ultimately rely on connective tissue and epithelial tissue to repair the wound. However, after human skin and mucous membranes are injured, not only the morphology and function of the cells in the injured area undergo pathophysiological changes, but also the injured cells and dead cells release a large number of active substances, such as histamine,...
