Abstract: Disclosed is a method for identifying lymphatic disease and disease states in mammals. The method uses a multi-angle light scatter flow cytometer to diagnose and treat mammals. The method includes collecting lymph node aspirate from a mammal; scanning the lymph node aspirate in a flow cytometer to generate a diagnostic scan; comparing the diagnostic scan to a known normal scan; identifying differences between the diagnostic scan and the known normal scan; and identifying similarities between the diagnostic scan and known disease scans to identify a cause of lymphadenopathy. Graphical representations of leukocyte identification are generated as a result of the scanning process. By using the graphs, a veterinarian or technician is able to diagnose the effectiveness or ineffectiveness of the treatment.

Abstract: A hydraulic system for a flow cytometry having a reservoir for a sheath solution, at least one syringe connected to the reservoir, the at least one syringe being driven by a motor, a single HGB module connected on an inlet side to a sample inlet which is connected to the flow cell by a single flow path passing through the HGB module, a single flow cell connected to the HGB module and at least one syringe on an inlet side of the flow cell, and to a waste container on an outlet side of said flow cell.

Abstract: The present invention is a flow cytometry-based hematology system useful in the analysis of biological samples, particularly whole blood or blood-derived samples. The system is capable of determining at least a complete blood count (CBC), a five-part white blood cell differential, and a reticulocyte count from a whole blood sample. The system preferably uses a laser diode that emits a thin beam to illuminate cells in a flow cell and a lensless optical detection system to measure one or more of axial light loss, low-angle forward scattered light, high-angle forward scattered light, right angle scattered light, and time-of-flight measurements produced by the cells. The lensless optical detection system contains no optical components, other than photoreactive elements, and does not include any moving parts. Finally, the system uses a unique system of consumable reagent tubes that act as reaction chambers, mixing chambers, and waste chambers for the blood sample analyses.

Abstract: An apparatus for protecting personnel and the environment from harmful emissions of radiation from a source thereof includes a plurality of shielding parts so located as to be in the path of the radioactive emissions and to absorb them so that an electrical potential difference between the shielding parts is established, due to different absorptions of radiation by them, a variable electrical load for consuming electrical power at a location remote from the radioactive source, and electrical conductors communicating the variable electrical load with such shielding parts. Although the invention is primarily intended for protecting personnel and the environment against emissions from radiation sources, such as radioactive wastes, it is also useful for shielding other sources of harmful radiated emissions. Also within the invention are processes for protecting personnel and the environment against radiation hazards.
