Human blood is liquid in human body, which functions to transport oxigen needed by cells to the whole body. Considering the important blood function, the Indonesian Red Cross (PMI) has to maintain its blood stock stability to ensure the blood availibility. But the problem that PMI has to encounter with is its blood over-supply which leads to blood disposal. To minimize its unnessary blood disposal, estimation of blood need is required. Data of blood demand is normalized first, then estimation is made using Neural Network Backpropagation. In this study the estimation is made to the blood type of Packet Red Cells (PRC), the blood cells stocked at PMI Kota Surabaya. The best simulation result is at epoch 3000 with function Y = 4542,33 – 1,64595 x – 0,244018 x^2 and an error of  0,020314.

The identification of human blood type stillrequires a fast and accurate device considering the number ofblood samples that need to be distributed and transfusedimmediately. In this study we propose a hardwareimplementation of human blood type identification devices usingfeedforward neural network algorithms on grayscale images ofblood samples. The images to be used are 32x32 pixels, 48x48pixels, 64x64, 80x80, and 9x96 pixels. The algorithm wereimplemented using VHSIC Hardware Description Language.With artifical neural network implemented on Xilinx FPGASpartan 3S1000, the success rate of detection by grouping by themean and median ratios of the number of '1' bits is more than75%.


On July 31, 1908, my preliminary communication on this subject was received by the Royal Society and was read on November 12, 1908. In this report attention was drawn to certain phenomena occurring when normal and immune human serum was allowed to act in the presence of normal and immune human blood cells. The whole of the investigations were carried out with human blood obtained from various infective and non-infective diseases in man. The technique adopted in all experiments was referred to in detail, and will not be described in the present communication. The most important results were obtained in the examination of the agglutinative properties of the blood when an interaction took place between serum and red cells. It was shown that auto-agglutination was a rare phenomenon, but iso-agglutination was common. In some instances hæm-agglutinated red cells were altered in shape and size, especially when the clumps were exceptionally large. Attention was drawn to the distinction between agglutination of red blood corpuscles and agglutination of rouleaux. Saturation experiments were performed, and the specificity of the various reactions was demonstrated. Immune serum from cases of infection with the bacillus typhosus was rendered specifically inactive by saturation with suitable red cells, although the bacterial agglutinins remained.

1. There is constantly some breaking down of red cells in the circulation by fragmentation. 2. The fragments of red cells, as well as whole red cells, are phagocytized and destroyed by clasmatocytes or endothelial phagocytes. 3. When there is an increase in fragmentation in abnormal or pathological states, desquamated endothelial cells of the blood stream, as well as the clasmatocytes of the tissues, increase proportionately and take in these fragments. These cells are to be distinguished from eosinophilic leucocytes by the nature of their granules, by the type of motility of the cells, and by a negative peroxidase test. 4. The desquamated endothelial cells, clasmatocytes, in the circulating blood are positive to the peroxidase test only when they have taken in positive material. 5. The monocytes show marked variations of the oxidase reaction in different species and to different techniques. With the Sato and Sekiya technique most monocytes of human blood are positive, while most of them in rabbit blood are negative, but both positive and negative reactions are found in both human and rabbit blood.

This is a combined study of two diffirent branches, photogrammetry and morphology of blood cells. The three dimensional quantitative analysis of erythrocytes using SEMP technique, electron computation technique and photogrammetry theory has made it possible to push the study of mophology of blood cells from LM, TEM, SEM to a higher stage, that of SEM P. A new path has been broken for deeply study of morphology of blood cells.In medical view, the abnormality of the quality and quantity of erythrocytes is one of the important changes of blood disease. It shows the abnormal blood—making function of the human body. Therefore, the study of the change of shape on erythrocytes is the indispensable and important basis of reference in the clinical diagnosis and research of blood disease.The erythrocytes of one normal person, three PNH Patients and one AA patient were used in this experiment. This research determines the following items: Height;Length of two axes (long and short), ratio; Crevice in depth and width of cell membrane; Circumference of erythrocytes; Isoline map of erythrocytes; Section map of erythrocytes.

SummaryGlu-plasminogen binds to platelets; the monocytoid line, U937, and the human fetal fibroblast line, GM1380 bind both plasminogen and its activator, urokinase. This study assesses the interaction of these fibrinolytic proteins with circulating human blood cells. Plasminogen bound minimally to red cells but bound saturably and reversibly to monocytes, granulocytes and lymphocytes with apparent Kd values of 0.9-1.4 μM. The interactions were of high capacity with 1.6 to 49 × 105 sites/cell and involved the lysine binding sites of plasminogen. Both T cells and non-rosetting lymphocytes and two B cell lines saturably bound plasminogen. Urokinase bound saturably to gianulocytes, monocytes, non-rosetting lymphocytes and a B cell line, but minimally to T cells, platelets and red cells. Therefore, plasminogen binding sites of high capacity, of similar affinities, and with common recognition specificities are expressed by many peripheral blood cells. Urokinase receptors are also widely distributed, but less so than plasminogen binding sites. The binding ol plasminogen and/ or urokinase to these cells may lead to generation of cell- associated proteolytic activity which contributes to a variety of cellular functions.
