Leukocytes or white blood cells have a characteristic characteristic of different cells. Determination of the impression of the number of leukocytes is determined in the number of cells in the field of view. While the number of viewable field cells expressed is still quite varied. The purpose of this study was to determine the number of leukocytes in the field of view and expressed the impression of a sufficient amount. This research was conducted at the Laboratory of Health Analyst Department Panrita Husada Bulukumba on 9 April 2017 to 14 July 2017. This type of research is a laboratory observation that aims to determine the criteria for assessing the impression of the number of leukocytes on a peripheral blood smear. Data analysis using statistical analysis is the average and standard deviations to determine the impression of the number of leukocytes and use 3 inspection zones. The results of this study obtained results in zone IV the number of leukocyte impressions said to be sufficient was 7-10, in zone V the number of leukocyte impressions said to be sufficient was 4-9, and in zone VI the number of leukocyte impressions said to be sufficient was 3-8.

Diaphragmatic Function

Free radicals are known to play an important role in modulating the development of respiratory muscle dysfunction during sepsis. Moreover, neutrophil numbers increase in the diaphragm after endotoxin administration. Whether or not superoxide derived from infiltrating white blood cells contributes to muscle dysfunction during sepsis is, however, unknown. The purpose of the present study was to examine the effect of apocynin, an inhibitor of the superoxide-generating neutrophil NADPH complex, on endotoxin-induced diaphragmatic dysfunction. We studied groups of rats given saline, endotoxin, apocynin, or both endotoxin and apocynin. Animals were killed 18 h after injection, a portion of the diaphragm was used to assess force generation, and the remaining diaphragm was used for determination of 4-hydroxynonenal (a marker of lipid peroxidation) and nitrotyrosine levels (a marker of free radical-mediated protein modification). We found that endotoxin reduced diaphragm force generation and that apocynin partially prevented this decrease [e.g., force in response to 20 Hz was 23 ± 1 (SE), 12 ± 2, 23 ± 1, and 19 ± 1 N/cm2, respectively, for saline, endotoxin, apocynin, and endotoxin/apocynin groups; P < 0.001]. Apocynin also prevented endotoxin-mediated increases in diaphragm 4-hydroxynonenal and nitrotyrosine levels ( P < 0.01). These data suggest that neutrophil-derived free radicals contribute to diaphragmatic dysfunction during sepsis.

Introduction. The search for methods of correcting pathogenetic disorders related to Mycobacterium tuberculosis, the causative agent of tuberculosis, a highly hazardous communicable and socially significant disease, determines the relevance of the research and its objective to study the role of citric and succinic acids in protective and adaptive processes in warm-blooded animals with connective tissue disorders induced by inactivated mycobacteria. Materials and methods. The study was conducted on male Wistar rats with diseases induced by complete Freund’s adjuvant (a mineral oil emulsion containing heat-killed Mycobacterium tuberculosis). The animals were given a feed-added mixture of organic acids at 17 mg/kg body weight (minimum) and 88 mg/kg body weight (maximum) for 4 weeks. Hematology and bio�chemistry tests were performed using standard methods. The activity of succinate dehydrogenase in blood lymphocytes was determined by the cytobiochemical method. X-rays were obtained using stationary veterinary imaging equipment. Results. The protective effect of carboxylic acids in the exposed animals with Freund’s adjuvant-induced leukocytosis (expressed by a 28 % increase in white blood cells compared to the negative control, p < 0.05), oxidative stress (expressed by an increase in the concentration of malondialdehyde (MDA) by 40 %, p < 0.001, and in inhibition of catalase by 4 %), and subchondral bone sclerosis was characterized by a dose-dependent reduction in immunotoxic manifestations of the disease such as normalization of the number of white blood cells (p < 0.05 compared to model animals); a 27 % reduction in MDA, p < 0.001, a 10 % catalase activation, p < 0.01; succinate dehydrogenase normalization, and a decrease in dystrophic changes in the articular system of animals. Conclusion. The results of hematological, biochemical and radiological tests prove that pathological biochemical and morphological changes related to administration of inactivated M. tuberculosis to warm-blooded animals can be modified by a mixture of citric and succinic acids added to feed, which allows a better understanding of the pathogenesis and an increased therapy effectiveness.

SUMMARYWhen ten cats were infected orally with undiluted or a 10−1 dilution of virulent feline infectious enteritis (panleucopaenia) virus, all developed severe leucopaenia followed by the development of demonstrable antibody, but none died. Eighteen of 29 cats given a 10−2 dilution of virus died of the disease. Three of the survivors had white blood cell counts of less than 4000 and three had counts between 4000 and 6000 cells. Although the remaining five animals never had individual counts of less than 6000 cells, the geometric means of these counts showed that a marked depression in the leucocyte counts had occurred. All surviving cats developed antibody.Among the ten cats dosed with either 10−3 or 10−4 dilution of virus, four died of feline infectious enteritis and three developed antibody after falls in the leucocyte counts. It is suspected that low dilutions of feline infectious enteritis virulent virus in cats produce a phenomenon similar to that reported by von Magnus (1954) with influenza virus in eggs.Leucopaenia is commonly defined as less than 4000 white blood cells/mm.3 of blood. Counts lower than this are usual in cats which either die of the disease or have received large doses of virus; they are less common in cats surviving after administration of diluted virus. Challenge of cats with pre-existing antibody did not provoke a depression in the leucocyte counts.

In many departments of cytology, cytogenetics, hematology, and pathology, research projects using high-resolution computerized microscopy are now being mounted for computation of morphometric measurements on various structural components, as well as for determination of cellular DNA content. The majority of these measurements are made in a partially automated, computer-assisted mode, wherein there is strong interaction between the user and the computerized microscope. At the same time, full automation has been accomplished for both sample preparation and sample examination for clinical determination of the white blood cell differential count. At the time of writing, approximately 1,000 robot differential counting microscopes are in the field, analyzing images of human white blood cells, red blood cells, and platelets at the overall rate of about 100,000 slides per day. This mammoth through-put represents a major accomplishment in the application of machine vision to automated microscopy for hematology. In other areas of automated high-resolution microscopy, such as cytology and cytogenetics, no commercial instruments are available (although a few metaphase-finding machines are available and other new machines have been announced during the past year). This is a disappointing product, considering the nearly half century of research effort in these areas. This paper provides examples of the state of the art in automation of cell analysis for blood smears, cervical smears, and chromosome preparations. Also treated are new developments in multi-resolution automated microscopy, where images are now being generated and analyzed by a single machine over a range of 64:1 magnification and from 10,000 X 20,000 to 500 X 500 in total picture elements (pixels). Examples of images of human lymph node and liver tissue are presented. Semi-automated systems are not treated, although there is mention of recent research in the automation of tissue analysis.
