There are provided a pharmaceutical raw material capable of exhibiting a uniform functionality and producing magnetic particle-containing drugs for diagnosis and medical treatments with a high reproducibility. The pharmaceutical raw material comprises a monodisperse colloid sterile aqueous solution of magnetic iron oxide fine particles having an average particle diameter of 5 to 30 nm, a saturation magnetization of 50 to 90 Am2 / kg and a coercive force of 0.1 to 1.6 kA / m. The pharmaceutical raw material can be produced by forming magnetic iron oxide fine particles in the form of a colloid aqueous solution, purifying the resultant colloid aqueous solution of superparamagnetic iron oxide particles by water-washing and removing water-soluble salts by-produced upon the reaction from the reaction solution by an ordinary method, and replacing a dispersing medium of the purified colloid aqueous solution with ultrapure water.

The invention discloses a purely-natural all-fruit sea-buckthorn chewable tablet. A preparation method of the purely-natural all-fruit sea-buckthorn chewable tablet comprises the following steps: (1) carrying out drying treatment on sea-buckthorn fruits; (2) carrying out tabletting treatment; (3) carrying out anti-bacterial and anti-mildew film laminating treatment; and (4) drying and sterilizing to obtain the purely-natural all-fruit sea-buckthorn chewable tablet. The anti-bacterial and anti-mildew film laminating treatment in the step (3) is finished by adopting an aqueous sterile solution containing 2-5% of licorice extract and 1-2% of water-soluble oligomeric chitosan to soak for 25-35 seconds and then draining. The purely-natural all-fruit sea-buckthorn chewable tablet without containing chemical additives has the advantages that the sea-buckthorn fruits can be intuitively seen, a user can obtain single-particle-restored sea-buckthorn fruits by brewing with boiling water, the convenience in eating, the pure natural property and the visibility of the chewable tablet are better than those of an existing sea-buckthorn product on the market; and simultaneously, based on the fact that the sea buckthorn is rich in vitamin C, the usage amount of the tablets can be determined by fully considering the recommended amount of the vitamin C for a human body on the production specifications, so that the need of the human body on the vitamin C can be met by only taking 1-2 tablets every day.

The invention relates to a reagent and a method for the quick release of nucleic acid. The reagent for releasing the nucleic acid is prepared by dissolving 0.01 to 0.5 milliliter per liter (the concentration of the surface bioactive peptide in the sterile aqueous solution of KCl is 0.01 to 0.5 mm / l) of the surface bioactive peptide in 50 to 200 milliliter per liter of sterile aqueous solution of KCl, and adding 0.01 to 2 percent (the concentration of the SDS, the LLS or the Chelex-100 in sterile water is 0.01 to 2 percent) of the SDS, the LLS or the Chelex-100, and 0.05 to 1 percent (volume) of ethanol, wherein the percentages are calculated based on the volume of the sterile water. The method for releasing the nucleic acid comprises the following steps of: taking the reagent for releasing the nucleic acid, and performing equivalent dilution on the reagent by using the sterile water according to different experimental purposes; balancing the diluted reagent to the room temperature, and then mixing the reagent uniformly; sub-packaging the mixture into a sample tube to be tested; adding a sample to be treated in the sample tube; and absorbing and beating the sample repeatedly for 5 to 10 times by a pipettor. The reagent for releasing the nucleic acid is safe to use and has a low production cost; and the method for releasing the nucleic acid is simple and convenient to operate.

The invention discloses a method for improving the efficiency of killing retained bacteria by aminoglycoside antibiotics through low ion shock. The method comprises the following steps of: preparing antibiotics into an antibiotic pretreatment solution with a certain concentration by adopting an isotonic solution or a sterile aqueous solution, wherein the isotonic solution is a 0.3M glycerol solution or a 0.9% Nacl solution, and the sterile aqueous solution is double distilled water. The antibiotic pretreatment solution is used for carrying out resuspension treatment on bacterial liquid containing retained bacteria to be killed. The method can greatly improve the efficiency of killing the remained bacteria by the aminoglycoside antibiotics, effectively eliminate the retention of bacteria, reduce the tolerance of the bacteria, and reduce the dosage and the administration time on the premise of achieving the same treatment effect, thereby reducing the side effect of the antibiotics.
