で表わされる蛍光偏光度Pを求めれば良い。The lymphocytes of cancer patients react specifically to cancer antigens (cancer proteins), and when the lymphocytes come into contact with this antigen or a substance similar to it, they are stimulated in some way. Changes in the cytoplasm caused by this lymphocyte stimulation are detected in an extremely short time as changes in the physical properties of the cells, such as fluorescence polarization. Therefore, as mentioned above, only lymphocytes are separated from the blood of a subject, mixed with cancer protein, stained with FDA, and when polarized excitation light is applied to the lymphocytes, the excitation of the fluorescence emitted is If the component with the same vibration direction as the light is I"' and the component with 10 vibration directions perpendicular to this is 11, then I' is QI, P - (Q is a constant) I" + QI, the degree of fluorescence polarization P expressed as All you have to do is ask for it.

In cancer patients, the number is 15, whereas in cancer patients it is 0.66 to 0.86.
It is. If the subject is a cancer patient, this method can also determine the type of cancer by changing the cancer protein. The present invention is based on the above-described diagnostic method, in which a sample is exposed to 20 polarized excitation light to generate fluorescence, and the degree of polarization of this fluorescence is electrically processed to diagnose whether or not it is cancer. To provide a cancer diagnostic device that can automatically perform the following.

In such an optical system,
First, the sample to be determined as to whether it is cancer or not is placed, the shutter 13 is opened, the shutter 19 is closed, the sample is illuminated with the observation transmission illumination system, and the sample is observed with the eyepiece 15. While doing so, the pits of the objective lens are aligned, and the part of the sample to be photometered is determined.

。Next, the shutter 13 is closed, the shutter 19 is opened, and illumination is performed using an epifluorescence polarization photometric illumination system. The sample illuminated with the polarized excitation light emits fluorescence, and this fluorescence is transmitted through the Wollaston prism 16 to the light receiving element 17a.
, 17b, the two orthogonal polarized components are received, and the aforementioned degree of polarization P is calculated through an amplifier and an arithmetic processing circuit, it is determined whether or not it is cancer, and the result is displayed on the display device 20. Ru. As explained above, according to the cancer diagnostic device of the present invention, the results are not only displayed dynamically but also photometrically measured using a microscope, so the amount of sample required is extremely small, and if used for mass cancer screening, it will be extremely It is valid.

照明にすることも可能である。In addition, a shutter is provided for each of the observation illumination system and the fluorescence polarization photometry illumination system, so that both illumination systems can be switched and used with a simple operation, making it possible, for example, to illuminate the sample with excitation light only during photometry. It is possible to make highly accurate judgments, such as by being able to prevent the effects of fluorescence quenching. Although epi-illumination is used as the photometric illumination system in the description of the embodiment, it is also possible to use transmitted illumination.

い。Also, a Wollaston prism is used in the analyzer to separate the two components and detect both components, but by rotating the analyzer for 90 minutes and synchronizing this with the light receiving element, both components can be detected. It's okay. Further, since the fluorescence is weak, a highly sensitive light receiving element is used, but it is not preferable that strong illumination light for observation be incident on this light receiving element. Therefore, a shutter may be provided at an appropriate position in front of the light receiving element so that light enters the light receiving element only during photometry.
