Haematological parameters, plasma iron concentration, and bodyweight were monitored in Melanoma-bearing Libechov Minipigs (MeLiM) from 5 to 18 weeks old. Animals with melanoma progression (P group) and spontaneous regression (SR group) were compared. The P group showed the lowest median values of red blood cell counts (RBC), haematocrit (HCT), haemoglobin concentration (HGB), and bodyweight, whereas the control white (tumour-free) pigs (C group) revealed the highest mean values of these parameters. The mean values of pigs with SR fell between the P and C groups. In addition, a stable concentration of plasma iron was found in the C group, while iron deficiency that increases with age was observed in the MeLiM groups. These results indicate that MeLiM are affected by cancer-related microcytic hypochromic anaemia. The lowest values of HGB, RBC, and HCT, together with the highest number of platelets (PLT) in the P group correspond to melanoma progression. Higher values of these parameters and lower PLT in the MeLiM pigs with SR reflected health improvement due to the destruction of melanoma cells during spontaneous regression. Monitoring of these haematological parameters can help distinguish MeLiM piglets with progression and spontaneous regression of melanoma in the early stages of postnatal development. The findings of this study correspond to findings in human patients in which cancer-related anaemia, thrombocytosis, and iron deficiency are often diagnosed.

OBJECTIVE: The aim of the study was to compare the haematological and biochemical profiles of eight sighthound breeds. DESIGN: Samples were taken from 192 individuals of the sighthound breeds (Whippet, Greyhound, Italian Greyhound, Sloughi, Saluki, Borzoi, Pharaoh Hound and Azawakh). Routine haematological and biochemical examinations were performed and the results were evaluated statistically. RESULTS: There were significant differences in haematology and clinical biochemistry among the sighthound breeds. The most similar laboratory profile to Greyhounds was found in Whippets. Italian Greyhounds had significantly higher alanine aminotransferase activity than other sighthounds, except Pharaoh Hounds. CONCLUSION: Application of the Greyhound laboratory profile to other sighthounds is not recommended because of the frequent differences in haematological and clinical biochemical reference intervals.

We studied the effects of social rank on the haematologic profile in a herd of 24 female Iberian red deer hinds. Social rank hierarchy was determined and blood samples were taken and analysed. After adjusting for age and body mass, dominance ranking showed a significant negative effect (ie, lower values in dominant hinds) on white blood cell (WBC) count, haemoglobin and haematocrit. Our results are similar to those reported for stressed individuals due to physical immobilisation, but do not support the predicted enhanced erythropoiesis due to higher levels of androgens. The results for WBC numbers may also reflect that subordinate hinds must allocate a higher amount of resources to immunity as a result of injuries incurred from dominant hinds, while simultaneously facing restricted access to food sources. For red blood cell (RBC) counts, the results may be due to subordinate hinds likely needing increased haematocrit and haemoglobin levels for fast flight responses. Our data show that social rank influences haematologic profile, and thus it should be considered when correctly interpreting blood analyses in social cervid species.

OBJECTIVES: Currently, many questions regarding the effect of anaesthetics to fish remain unresolved. Fish species may differ widely in their response to an anaesthetic, the screening of dosages is often necessary. The aim of this study was to compare the effect of tricaine methane sulphonate (MS 222), clove oil, 2-phenoxyethanol and Propiscin on haematological profiles, oxidative stress biomarkers and antioxidant enzymes in barbel (Barbus barbus). DESIGN: The haematological profiles, oxidative stress biomarkers and antioxidant enzymes of barbel were evaluated immediately after a 10 min anaesthesia (MS 222--100 mg.L(-1), clove oil--33 mg.L(-1), 2-phenoxyethanol--0.4 mg.L(-1), Propiscin--1.0 mg.L(-1)), and 24 h after anaesthesia. RESULTS: The 10 min exposure in the recommended concentrations of tested anaesthetics have no significant effect on haematological profiles, levels of thiobarbituric acid reactive substances, and activity of glutathione reductase of barbel. The activity of superoxide dismutase (SOD) was significantly decreased (p<0.01) in the muscle in all experimental groups. The activity of SOD showed a significant decrease (p<0.01) in the liver 24 h after all anaesthetics; however in the gill the activity of SOD was significantly increased (p<0.01) in Propiscin (10 min). The activity of catalase (CAT) was significantly increased (p<0.05) in the muscle 24 h after all anaesthetics. CONCLUSIONS: The observed effects on barbel antioxidant systems may be a defence against oxidative damage. The results of this study suggest that the antioxidant systems of barbel are altered by Propiscin anaesthesia, but are slightly affected by MS 222, clove oil, and 2-phenoxyethanol anaesthesia.

OBJECTIVES: The objectives of the study were to compare the effects of Propiscin, 2-phenoxyethanol, clove oil and tricaine methane sulphonate (MS 222), anaesthetics frequently used in aquaculture. DESIGN: The haematological and biochemical blood profiles of pikeperch (Sander lucioperca L.) anesthetized with Propiscin (1.5 ml L-1), 2-phenoxyethanol (0.3 ml L-1), clove oil (33 mg L-1), MS 222 (150 mg L-1) and non-anesthetized control group were tested. Each tested group was divided into two subgroups, the first subgroup was sampled in anaesthesia 10 min after application of the anaesthetic and the second one live on 24h. RESULTS: The erythrocyte count and haematocrit was significantly decreased in 2-phenoxyethanol (24 h) compared with control group (CG). The mean corpuscular haemoglobin concentration was significantly increased in 2-phenoxyethanol (10 min), Propiscin (10 min and 24 h) compared to CG. The 2-phenoxyethanol (10 min and 24 h), MS 222 (24 h), clove oil (24 h), and Propiscin (10 min and 24 h) showed significantly lower leukocyte count compared with CG. The level of glucose was significantly (p<0.05) elevated with MS 222 (10 min) and clove oil (10 min) compared with CG. The 2-phenoxyethanol (10 min and 24 h), MS 222 (24 h), clove oil (24 h), and Propiscin (24 h) showed significantly lower (p<0.01) ammonia levels compared with CG. The triacylglycerols was significantly decreased (p<0.01) with Propiscin (10 min and 24 h), MS 222 (24 h), clove oil (24 h) and with 2-phenoxyethanol (24 h) compared with CG. After 24 hours MS 222 (24 h) and Propiscin (24 h) anaesthesia, fish showed significantly lower (p<0.01) concentration of inorganic phosphate compared with CG. CONCLUSIONS: On the basis of this experiment, it appears that clove oil was associated with the lowest effects in pikeperch and therefore would be recommended as an alternative to MS 222, while Propiscin and 2-phenoxyethanol are not suitable for manipulation with pikeperch in aquaculture.

OBJECTIVES: Effect of long-term oral administration of three different concentrations (0.5, 1.0, and 2.0%) of micronized β-1.3/1.6-D-glucan derived from oyster mushroom (Pleurotus ostreatus, Hiratake) on biometrical, haematological, biochemical, and immunological indices of half-year-old rainbow trout (Oncorhynchus mykiss) was assessed in the study. Design: Rainbow trout were feed commercial feed pellets containing β-1.3/1.6-D-glucan in the concentrations of 0.5, 1.0, and 2.0% for 85 days. Biometrical indices consisted in total and standard length, body and liver weight, from which derived somatic parameters such as Fulton´s condition factor and hepatosomatic index were calculated. Haematological parameters were evaluated according to unified methods for haematological examination in fish. Plasma biochemical profile was analysed using biochemical analyser Konelab 20i and Easy Lyte Analyzer. A phagocyte cells metabolic activity (induced chemiluminescence of phagocytes) was determined as an immunological parameter by a microplate luminometric method on Immunotech LM-01T. Results: No clinical signs of behavioral, respiratory, or neurologic distress were observed in rainbow trout. Fish showed normal feeding behavior. As for biometric parameters, no significant changes in total and standard length, body weight, liver weight, as well as in condition factor and hepatosomatic index of experimental and control fish were found. In the course of the study, weight gains in rainbow trout were similar and continuous. Shifts in PCV (p<0.05), haemoglobin (p<0.05), and MCHC (p<0.01) were found within haematological indices. Plasma concentration of glucose, lactate, total protein, cholesterol, calcium, natrium, potassium (all p<0.05), albumins and chlorides (both p<0.01), as well as catalytic activities of ALT and AST (both p<0.05) were changed in the course of the study. A phagocyte cells metabolic activity (luminol-induced chemiluminescence) in rainbow trout was not altered by oyster mushroom β-1.3/1.6-D-glucan administration. Conclusion: After long-term oral administration of three concentrations of micronized β-1.3/1.6-D-glucan derived from oyster mushroom (Pleurotus ostreatus, Hiratake) shifts in haematological and biochemical profiling were found in half-year-old rainbow trout (O. mykiss) in environmental conditions of a commercial rainbow trout fishery. Biometrical indices were not found significantly altered. No specific effect of β-glucan on immune system response of rainbow trout was found in the study. The use of β-glucan in prosperous, clinically healthy aquaculture is still an issue, nevertheless, its use in breedings endangered by stress stimuli, infectious diseases or adverse environmental factors is indisputable.

Nádory krvi, krvotvorného a lymfatického tkaniva sú v zásade všetky malígne. Napriek povzbudivým výsledkom v liečbe sa rizikový profil pacienta s hematologickou malignitou plne odhalí napr. až v čase operačného zákroku. Existuje celý rad rizikových faktorov v predoperačnom a pooperačnom čase, ktoré môžu mať zásadný význam na ovplyvnenie výsledku operačného výkonu. Medzi najdôležitejšie patrí samotný nádorový proces (jeho anatomická lokalizácia, vplyv na hemostázu a krvný systém), ako aj efekt protinádorovej liečby.

Tumours of blood, hematopoietic and lymphoid tissues are all basically malignant. Despite very encouraging results in the treatment, the risk profile of the patients with haematological malignancies will be fully revealed e.g. at the time of surgery. There are a number of risk factors in the preoperative and postoperative time, which may have a crucial influence on the outcome of the surgery. The most relevant factors are: the tumour process itself (its anatomical location, the effect on haemostasis and blood system), as well as the effect of the cancer therapy.

The aim of the study was to evaluate the effect of micronized β-1.3/1.6-D-glucan (BG) derived from the oyster mushroom Pleurotus ostreatus Hiratake and tetracycline antibiotic oxytetracycline (OTC) on biometrical, haematological, biochemical, and immunological indices, and histopathological changes in tissues of one- to two-year-old common carp (Cyprinus carpio L.). The fish tested were divided into five experimental groups and one control. Carp in the control group were fed commercial carp feed pellets. Fish in the five experimental groups were fed the same pellets supplemented with either OTC, a combination of OTC and BG, or BG as follows: 75 mg oxytetracycline kg(-1) bw (OTC group), 75 mg oxytetracycline kg(-1) bw and 0.5% β-glucan (OTC + 0.5% BG group), 75 mg oxytetracycline kg(-1) bw and 2.0% β-glucan (OTC + 2.0% BG group), 0.5% β-glucan (0.5% BG group), and 2.0% β-glucan (2.0% BG group). OTC- and BG-supplemented diets and the control diet were administered to experimental and control carp for 50 days (i.e. samplings 1-3, the exposure period); for the following 14 days, fish were fed only control feed pellets with no OTC or BG supplementation (i.e. sampling 4, the recovery period). Blood and tissue samples were collected both during, and at the end of the study. No significant changes in biometrical indices (i.e. total length, standard length, total weight, hepatosomatic and spleen somatic index, and Fulton's condition factor) were found in experimental carp compared to control in any sampling. In haematological indices, significant changes were found only in sampling 2, in which shifts in PCV (P < 0.01), Hb (P < 0.01), and WBC (P < 0.01), and in the counts of lymphocytes (P < 0.01), monocytes (P < 0.01), and neutrophil granulocytes-segments (P < 0.05) were revealed. As for biochemical profiling, plasma concentrations of glucose, albumins, cholesterol, natrium, and chlorides (all P < 0.01), and total proteins, lactate, phosphorus, and potassium (all P < 0.05) as well as the catalytic activity of ALP (P < 0.05) were altered in common carp. A significant change in induced (opsonizedzymosan particles, OZP) chemiluminescence (P < 0.05) in sampling 3 and no shifts in serum immunoglobulins concentration were found in the immunological analysis. Histopathological examination of skin, gills, liver, spleen, and cranial and caudal kidneys revealed no obvious specific changes in any tissue analysed. The use of β-glucans in clinically healthy aquaculture remains an issue. Nevertheless, their use in breeding endangered by stress stimuli, infectious disease, or adverse environmental factors is defensible.

In this multi-centre study, we analysed the prognostic impact of mutations in 19 genes associated with myeloid malignancies in 258 newly diagnosed acute myeloid leukaemia patients (aged 19-70 years) undergoing intensive therapy. We identified five patient groups with different prognostic risks and different benefits from allogeneic hematopoietic stem cell transplantation (alloHSCT) within the intermediate cytogenetic risk group patients (n = 184). The most adverse prognosis was observed in patients with DNMT3A and FLT3-ITD co-mutation, whose survival could be significantly improved with alloHSCT. In contrast, the most favourable prognosis without any further benefit from alloHSCT was identified in patients with mutations in NPM1 or CEBPA, after exclusion of the unfavourable prognostic groups defined by mutations in DNMT3A, RUNX1 or genes from chromatin/spliceosome group. An additional analysis of 113 diagnosis-remission paired samples revealed that persistence of non-DNMT3A mutations (above 2% VAF) represented a further negative prognostic factor. The proposed model offers a possible molecular stratification and treatment guidance for intermediate cytogenetic risk group patients.
