The present application relates to the field of concentration detection, and specifically to a kind of experimental drug concentration rapid determination instrument, including extraction assembly, centrifugal component and material taking assembly, the extraction assembly includes extraction cup, stirring assembly is installed in the inside of extraction cup, the stirring assembly includes with the outer stirring rod of extraction cup rotation connection, inner stirring rod and helical blade;It further includes scraping component, the scraping component includes with the inner scraper of helical blade sliding connection, with the middle scraper of inner stirring rod sliding connection and with the outer scraper of outer stirring rod sliding connection.The present application is integrated by stirring extraction and centrifugal purification function, without sample transfer, the degree of automation of high integration equipment, to solve the pain points of sample loss, pollution, cumbersome process, low degree of automation in the prior art, meet the efficient, accurate demand of pharmacokinetic experiment and all kinds of biological, chemical sample pretreatment, provide stable support for subsequent automatic material distribution, detection link.

The utility model discloses a rapid distinguishing device for a control medicine and an experimental medicine, and belongs to the technical field of tea processing equipment. Which comprises a hinge seat, the middle section of the hinge seat is provided with a long rod, and is characterized in that the surface of the hinge seat is sleeved with a plurality of material storage structures, the top of the uppermost material storage structure is provided with a display disc, and the bottom of the lowermost material storage structure is provided with a bottom disc; lamp holders are arranged on one side of the top and one side of the bottom of the rear side of the hinge seat; according to the utility model, the plurality of storage structures are stacked up and down, and the storage structures are rotationally connected through the long rods of the hinge seats on one sides, so that each independent storage structure can be rotationally opened, and actual storage and taking are facilitated; the interior of the material storage disc is divided into two cavities for storing control medicine and experiment medicine through the partition plate, so that the corresponding medicine can be quickly found during subsequent taking.

The invention discloses a research method for reducing atherosclerosis risk mechanism, and belongs to the technical field of medicine application. Selecting laboratory mice, feeding the laboratory mice in a 12-hour light-dark period environment, replacing the laboratory mice with high-phosphorus feed, continuously feeding the laboratory mice, monitoring the serum phosphorus level, and grouping the mice which reach the standard; respectively preparing experimental drugs for each group of mice through calcium carbonate, calcium acetate, sevelamer and a composite drug, administering the experimental drugs to the mice in the group, and monitoring the body weight and the serum phosphorus level and adjusting the administration dosage during the period; dynamic monitoring is alternately carried out during administration, and the dynamic monitoring comprises metabolism cage monitoring and blood fat and inflammation detection; collecting blood, aorta and kidney samples after administration; and atherosclerotic plaques and kidney tissues are detected. The invention verifies whether the phosphorus-binding agent phosphorus-reducing drug can reduce the risk of atherosclerosis of hyperphosphatemia patients by reducing the serum phosphorus level, improving blood lipid metabolism, reducing inflammatory response, improving vascular functions and the like, and provides a theoretical basis for clinical treatment.
