Comparison between different sources of minerals in horses with nutritional secondary hyperparathyroidism / [Comparação entre diferentes fontes de minerais em cavalos com hiperparatireoidismo secundário nutricional]

Minerals perform several functions in the body, such as coagulation actions, muscle contraction, enzymatic and hormonal production, among others. This study aims to evaluate the effect of a 150 days chelated and not chelated mineral supplementation with and without potassium oxalate on serological parameters and bone mineral density of horses. Twenty-four crossbred yearlings (12 females and 12 males) with an average age of 21±3 months and body weight of 330.8±37.9kg were divided into four groups containing six equines in each (three females and three males) in a completely randomized design with repeated measurements in a 2x2 factorial arrangement. Treatments were: 1 - chelated minerals compound; 2 - chelated minerals compound and potassium oxalate; 3 - not chelated minerals compound; and 4 - not chelated minerals compound and potassium oxalate. Clinical signs of nutritional secondary hyperparathyroidism (NSH) were observed only in treatment 4. Results showed no treatment effect in bone biopsy for calcium, phosphorus and bone density. There were significant reductions of parathyroid hormone (PTH) means concentrations in treatments 2 and 4 during supplementation. Animals supplemented with chelated minerals compounds avoided mineral imbalances and NSH even when in dietary potassium oxalate challenged.(AU)

Os minerais desempenham diversas funções no organismo, como ações de coagulação, contração muscular, produção enzimática e hormonal, entre outras. O objetivo deste estudo foi avaliar o efeito da suplementação de minerais quelatados e não quelatados, por 150 dias, com e sem oxalato de potássio, sobre parâmetros sorológicos e densidade mineral óssea em equinos. Vinte e quatro filhotes mestiços (12 fêmeas e 12 machos), com idade média de 21±3 meses e peso corporal de 330,8±37,9kg, foram divididos em quatro grupos contendo seis equinos cada (três fêmeas e três machos), em delineamento inteiramente ao acaso, com repetição medida em arranjo fatorial 2x2. Os tratamentos foram: 1 - composto mineral quelatado; 2 - composto mineral quelatado e oxalato de potássio; 3 - composto mineral não quelatado; e 4 - composto mineral não quelatado e oxalato de potássio. Os sinais clínicos do hiperparatireoidismo secundário nutricional (NSH) foram observados apenas no tratamento 4. Os resultados não mostraram efeito de tratamento na biópsia óssea para cálcio, fósforo e densidade óssea. Houve redução significativa do hormônio da paratireoide (PTH) em concentrações médias nos tratamentos 2 e 4 durante a suplementação. Os animais suplementados com compostos minerais quelatados evitaram desequilíbrios minerais e NSH, mesmo quando desafiados no oxalato de potássio na dieta.(AU)

A multi-center research on the establishment and validation of autoverification rules for blood analysis / 中华检验医学杂志

Objective@#To establish a set of rules for autoverification of blood analysis, in order to provide a way to validate autoverification rules for different analytical systems, which can ensure the accuracy of test results as well as shorten turnaround time (TAT) of test reports.@*Methods@#A total of 34 629 EDTA-K2 anticoagulated blood samples were collected from multicenter cooperative units including the First Hospital of Jinlin University during January 2017 to November 2017. These samples included: 3 478 cases in Autoverification Establishment Group, including 288 cases for Delta check rules; 5 362 cases in Autoverification Validation Group, including 2 494 cases for Delta check; 25 789 cases in Clinical Application Trial Group. All these samples were analyzed for blood routine tests using Sysmex XN series automatic blood analyzers.Blood smears, staining and microscopic examination were done for each sample; then the clinical information, instrument parameters, test results and microscopic results were summarized; screening and determination of autoverification conditions including parameters and cutoff values were done using statistical analysis. The autoverification rules were input into Sysmex Laboman software and undergone stage Ⅰ validation using simulated data, and stage Ⅱ validation for post-analytical samples successively. True negative, false negative, true positive, false positive, autoverification pass rate and passing accuracy were calculated. Autoverification rules were applied to autoverification blood routine results and missed detection rates were validated, and also data of autoverification pass rate and TAT were obtained.@*Results@#(1)The selected autoverification conditions and cutoff values included 43 rules involving WBC, RBC, PLT, Delta check and abnormal characteristics. (2)Validation of 3 190 cases in Autoverification Establishment Group showed the false negative rate was 1.94%(62/3 190)(P<0.001), autoverification pass rate was 76.74%, passing accuracy was 97.47%; Validation of 2 868 cases in Autoverification Validation Group, the false negative rate was 3.38%(97/2 868)(P=0.002), autoverification pass rate was 42.26%, passing accuracy was 92.00%; Validation of Delta check on 288 cases in Autoverification Establishment Group and 2 494 cases in Autoverification Validation Group showed the false negative rates were respectively 1.39% and 2.61%(P<0.001). (3)Three hospitals adopted these rules of autoverification for 25 789 blood routine samples, and found that the average TAT of blood routine test reports were shortened by 24min, 32min and 7min respectively, the rate of samples reported within 30min were elevated by 33%, 53% and 7%. The autoverification pass rates were 72%-74%.@*Conclusions@#The application of this set of 43 autoverification rules in blood sample analysis can ensure test quality while shortenTAT and improve work efficiency. It is worth pointing out that for the same analytical systems in this research, validation is necessary before application of this set of rules, and periodic validation is required during application to make necessary adjustment; for different analytical systems, as this research provide a way to establish autoverification rules for blood routine tests.Clinical labs may establish their own suitable autoverification rules on the basis of technological parameters.

Toxicological Investigation of Ethanolic Extract of Epipremnum aureum in Rodents.

The present study was aimed to explore the acute and sub chronic toxicity studies with orally administered ethanolic leave extract of Epipremnum aureum. For the acute toxicity study, the animals were divided into four groups and each group receives a dose of (50, 500, 2000) mg/kg except control group which receives only 1% CMC. They were observed for 14days for signs of toxicity. In case of sub chronic toxicity, the Sprague dawley rats were fed with ethanol extract (100, 600, and 1000) mg/kg per day for 28 days. The parameters measured include organ weight, biochemical test, haematological test and histopathological observations. Acute oral administration of Epipremnum aureum did not show any mortality, CNS and ANS toxicities. Similarly in subchronic toxicity studies, Epipremnum aureum did not show any visible signs of toxicity. There were also no significant differences between the control and extract treated groups in terms of their organ weight, haematological and biochemical parameters. Histopathological examination did not reveal any remarkable and treatment related changes. A no-observed adverse-effect level for extract is 2000 mg/kg for rats under the conditions of this study. Hence, the extracts could be considered safe at the doses administered since they did not provoke toxic effect on the key organs examined and also did not alter any biochemical and haematological parameters.

Automatic segmentation and classification of blood components in microscopic images using a fuzzy approach

INTRODUCTION: Automatic detection of blood components is an important topic in the field of hematology. Segmentation is an important step because it allows components to be grouped into common areas and processed separately. This paper proposes a method for the automatic segmentation and classification of blood components in microscopic images using a general and automatic fuzzy approach. METHODS: During pre-processing, the supports of the fuzzy sets are automatically calculated based on the histogram peaks in the green channel of the RGB image and the Euclidean distance between the leukocyte nuclei centroids and the remaining pixels. During processing, fuzzification associates the degree of pertinence of the gray level of each pixel in the regions defined in the histogram with the proximity of the leukocyte nucleus centroid closest to the pixel. The fuzzy rules are then applied, and the image is defuzzified, resulting in the classification of four regions: leukocyte nuclei, leukocyte cytoplasm, erythrocytes and blood plasma. In post-processing, false positives are reduced and the leukocytes (including the nucleus and cytoplasm), erythrocytes and blood plasma are segmented. RESULTS: A total of 530 microscopic images of blood smears were processed, and the results were compared with the results of manual segmentation by experts and the accuracy rates of other approaches. CONCLUSION: The method demonstrated average accuracy rates of 97.31% for leukocytes, 95.39% for erythrocytes and 95.06% for blood plasma, avoiding the limitations found in the literature and contributing to the practice of the segmentation of blood components.

Clinical utility of live blood analysis

BACKGROUND: Recently Live blood analysis was populated in korean society. so we evaluated clinical utility of Live blood analysis, as compared the Live blood analysis result of patients who have confirmed diagnosis of disease with that of controls who have no known health problems. METHODS: We carried out Live blood analysis to patients(n=30) who was entered to an admission in Yongdong severance hospital from February 2000 to March 2000 and to controls(n=30) who worked in that hospital at same time. We examined 3 abnormal finding; rouleau formation, spicule, protoplast, which were often observed in Live blood analysis. RESULTS: At comparison of patient group and control group, rouleau formation was observed in 27 patients except 3 patients and it was observed in all 30 controls. Spicule was observed 2in 9 patients except 1 patients and it was observed in all 30 controls. Protoplast was observed in 16 patients and 13 controls. There was no difference between patients and controls in observing 3 abnormal finding. CONCLUSION: We conclude that Live blood analysis may have no clinical significance.

Studies with the copper sulfate specific gravity method of blood analysis: I. hemoglobin, hematocrit and plasma protein values of normal Filipino students

1. Hemoglobin, hematocrit and plasma protein values calculated from the specific gravities of plasma and whole blood determined by the copper sulfate method in 85 normal male and 30 normal female Filipino students are reported2. The mean hemoglobin is 15.78 +/- 0.97 Gm./100 ml. for males; 13.83 +/- 0.70 Gm./100 ml. for females. The mean hematocrit value is 46.63 +/- 2.84 volume % (cells) for males and 40.97 +/- 2.24 volume % (cells) for females. The mean plasma protein concentration is 7.44 +/- 0.40 Gm./100 ml. for males and 7.41 +/- 0.31 Gm./100 ml. for females, with a mean of 7.435 +/- 0.38 Gm./100 ml. for all subjects3. The values obtained in this study are compared with values previously reported for normal Filipino adults and with values given by foreign authors for normal adults of other races4. The fact that our hemoglobin and plasma protein values are higher than any reported by previous workers on Filipino adult subjects indicates the need at present for a re-evaluation of our physiologic standards.

Comparison of Gas Analysis in Arterial and Venous Blood during Inspiration of High Oxygen Concentration / 대한마취과학회지

This investigation was undertaken to determine whether venous blood, sampled under carefully controlled conditions, was an acceptable alternative to arterial blood for the measurement of arterial blood gas analysis. The arterial values for Pco2, pH, base excess and oxygen saturation were compared with the values of blood samples drawn simultaneously from the cephalic, external jugular and internal jugular vein during inhalation general anesthesia with 50% oxygen concentration in 25 cases. The results were as follows: 1) The blood gas analysis values of cephalic venous blood were closely comparable to those of arterial blood. There was no significant difference between the Pci2, pH and base excess of cephalic venous and arterial blood. 2) Although the oxygen partial pressure in cephalic venous blood was significantly less than that in arterial blood, the difference in oxygen saturation was small. 3) The blood gas analysis values of external jugular venous blood were between the cephalic venous blood and the internal jugular venous blood values. Those show that venous blood was arterialized and in general anesthesia, it's Pco2, pH and oxygen saturation will be near endough to those of the arterial blood. Although the oxygen partial pressure in venous blood was significantly less than that in arterial blood, the difference in oxygen saturation was small. Therefore arterialized venous blood from the cephalic vein may provide a reasonable estimate of presence or absence of hypoxia. in this study, we feel that the use of cephalic venous blood for Pco2, pH and oxygen saturation determination during general anesthesia is a reliable indirect method of arterial blood sampling.
