An apparatus and method of automated blood cell analysis uses technologies from other systems to create a new, robust, improved type of automated microscope, which uses electronic motors and a closed loop control system to minimize ambient factors, such as jarring and temperature changes. Pre-stained blood smear slides are first coated with a thin film of oil and are loaded into a carousel from which they can individually be analyzed. The slides are moved under a low magnification microscope; an optimal area of examination is determined; a focal plane map is calculated for that area, and the positions of white blood cell candidates are computed. The slide is then moved under a high power microscope where a refined focal plane map is computed and the individual white blood cell candidates are imaged. The cells are preclassified and the images are made available for analysis by the technician. Additionally, samples of red blood cells, equivalent to what the technician would do manually, are imaged and presented to the technician for evaluation. The technician may make notes on those cells, both red and white blood cells and archive them.

The invention discloses an anti-tumor agent, beverage and food using the agent and a manufacturing method of the anti-tumor agent. The antitumor agent of the present invention exhibits specific effects on human tumor cell A4573 and mouse melanoma B16 cell. In addition, according to the microscopic observation of the live blood cell analysis method, it was found that each erythrocyte in the blood was separated and formed into a perfect circle, and abnormally shaped erythrocytes such as acanthocytes were normalized, and the diameter of white blood cells was more than 2.5 times that of erythrocytes. The anti-tumor agent exhibits multiple immune activities in addition to having immune activities against tumors. Beverages and food containing the antitumor agent can be used as health food and the like. The production method of the anti-tumor agent comprises: heating wheat germ and the like at 110° C. with steam for 3 hours, and then fermenting with microorganisms such as koji at 30° C. for 48 hours.

The present invention relates to a treatment method capable of making biological red blood cell volume be stable for a long-period, and is used for preparing quality control material and reference material for blood cell analysis. Said treatment method includes the following steps: (1), stopping or reducing melabolism of red blood cell; (2), phospholipids component treatment for stabilizing red blood cell membrane; and (3), treatment for stabilizing red blood cell membrane protein. The effective component of chemical reagent used in step 2 includes manganic acid, cadmic acid, chromic acid and picric acid or metal salts correspondent to these acids, and the effective component of chemical reagent used in step 3 includes aldehyde material, and the chemical reagents used in the step 1 include the chemical reagents used in step 2 and step 3. Said treatment process can be implemented at room temperature.
