Provided is an oral care composition capable of completely preventing cavities by inducing the secretion of saliva in large quantities and thereby maintaining and improving the health of the oral cavity. Specifically provided is an oral care composition that is placed in the oral cavity to improve the health of the oral cavity, said oral care composition being characterized by comprising, in termsof mass% relative to the total mass of the composition, 1-30% phosphoryl organosaccharides of calcium, 0.01-10% lactoferrin, and 1-5% magnesium carbonate or 1-5% suicralose.

The invention relates to a perfusion bioreactor system which comprises a circulating perfusion system, a constant temperature system, a gas exchange system and an on-line monitoring system, wherein the circulating perfusion system comprises a culture chamber, a liquid storage bottle and a peristaltic pump which are sequentially connected through a pipeline to form a perfusion culture loop; the constant temperature system comprises a constant temperature water bath device of which the inside is provided with a circuitous circulating pipeline, and is applicable to an electric heating and refrigerating control part; the gas exchange system is composed of a gas filter, a gas flowmeter, a high-pressure gas bottle, a pressure relief valve and a connecting pipeline; and the on-line monitoring system is composed of a monitoring probe, a monitor terminal, monitoring software, a data conversion chip and a mass transfer regulator. The perfusion bioreactor system provided by the invention can maximally simulate the in-vivo microenvironment in the tissue or organ in-vitro construction process, ensures sufficient substance exchange and normal physiological functions of seed cells in the biological material, enhance the yield of the seed cell / biological stent material, shorten the culture period and lower the culture cost.
