A small proportion of cases of chronic granuloid leukemia is associated with an extraordinary concentration of leukocytes in the blood. As a result of the hyperleukocytic syndrome, these cases present special problems and complication that may seriously affect on patients’ life and the quality of life to the physicians. Leukapheresis is an effective method of therapy in these cases which can reverse the hyperleukocytic syndrome rapidly and decrease the tumor cell mass so as to minimize the extent of chemotherapeutic-induced cytolysis and the cytolysis- induced complications.

The count and recognition of white blood cells in blood smear images play an important role in the diagnosis of blood diseases including leukemia. Traditional manual test results are easily disturbed by many factors. It is necessary to develop an automatic leukocyte analysis system to provide doctors with auxiliary diagnosis, and blood leukocyte segmentation is the basis of automatic analysis. In this paper, we improved the U-Net model and proposed a segmentation algorithm of leukocyte image based on dual path and atrous spatial pyramid pooling. Firstly, the dual path network was introduced into the feature encoder to extract multi-scale leukocyte features, and the atrous spatial pyramid pooling was used to enhance the feature extraction ability of the network. Then the feature decoder composed of convolution and deconvolution was used to restore the segmented target to the original image size to realize the pixel level segmentation of blood leukocytes. Finally, qualitative and quantitative experiments were carried out on three leukocyte data sets to verify the effectiveness of the algorithm. The results showed that compared with other representative algorithms, the proposed blood leukocyte segmentation algorithm had better segmentation results, and the mIoU value could reach more than 0.97. It is hoped that the method could be conducive to the automatic auxiliary diagnosis of blood diseases in the future.

The purpose of this experiment is to examine if purified Korean red ginseng extracts could have an effect on leukocyte migration and to select the best chemotactic factor for leukocyte migration. When chemotactic factor such as TC-199 medium, milk and filtrate of E.coli culture for 48hrs at 37'C extracts was used and adquet incubation periods was 60 minutes at 37'C. The various purified Korean red ginseng extract was stimulated for the leukocytes migration in modified Boyden chamber, however fraction number 2 and 4 were shown most active migration through the filter. This mean was effect an enhancement of immunological activity to leukocyte migration in vivo.
