Differential diagnosis of reasons for the accumulation of abdominal fluid is a significant clinical problem. The examination and analysis of ascites fluid is a practical method which may provide a lot of useful information enabling the diagnosis of ascites fluid etiology. The aim of the study was to evaluate the usefulness of examining abdominal fluid and laboratory parameters in differential diagnosis of ascites in dogs and to examine ascites etiology. The study was conducted on 72 dogs with ascites. On the basis of the obtained results, the dogs were divided into 5 groups: 1. 38 dogs with ascites resulting from circulatory insufficiency, 2. 23 dogs with ascites resulting from a neoplastic disease, 3. 7 dogs with ascites resulting from a liver disease, 4. 2 dogs with ascites associated with septic peritonitis, 5. 2 dogs with ascites associated with intestinal diseases. The examinations were conducted according to the following pattern: anamnesis and clinical examination, USG, ECG, morphological and biochemical examination of selected blood parameters, abdominocentesis and peritoneal fluid examination. The fluid collected from the peritoneal cavity was evaluated according to Light’s criteria modified by the author (colour, translucency, special gravity, pH, total protein concentration, glucose, triglycerides, cholesterol, amylase activity, lactic dehydrogenase, leukocyte count, microbiological and cytological examination of the fluid). Based on the results of biochemical blood and ascites fluid examinations, the serum-ascites protein gradient and serum-ascites albumin gradient were calculated. The conducted research led to the following conclusions: the most frequent cause of ascites in dogs is a chronic heart failure, the fluid composition depends on the location and the character of the disease process resulting in ascites, the determination of the leucocyte count in the peritoneal fluid is a significant criterion enabling differentiation of ascites caused by a neoplastic disease, the determination of amylase activity, lactic dehydrogenase and glucose concentration in the peritoneal fluid enables differentiation of ascites of neoplastic etiology, the determination of triglycerides and cholesterol concentration in the peritoneal fluid enables differentiation of ascites caused by liver diseases.

Mozliwosci retencjonowania wod w zlewni rzeki Dadaj

63%
Spośród wszystkich elementów budujących przestrzeń krajobrazową, najbardziej zagrożone jest środowisko wodne. Znaczący na skalę globalną ubytek zasobów dyspozycyjnych wód doprowadził do upowszechnienia metodologii retencjonowania wód powierzchniowych i podziemnych. W badanej zlewni rzeki Dadaj (334,6 km²) istnieje możliwość powiększenia retencji powierzchniowo-gruntowej o wartość 45,9 mln m³ przy obecnym poziomie 190,8 mln m³. Wymieniony efekt magazynowania wód możemy uzyskać drogą piętrzenia jezior przepływowych, reaktywizacji mokradeł dolinowych, regeneracji „oczek wodnych”, a także poprzez wykonanie zabiegów agro- i fitomelioracyjnych na glebach użytków rolnych i leśnych. Warunkiem powodzenia proponowanych przedsięwzięć jest realizacja melioracji ekologicznych (biologiczna regulacja rzek, przestrzenne rozmieszczenie zbiorników wodnych oraz zadrzewień śródpolnych i brzegowych), które w tej sytuacji stanowiłyby bazę wyjściową do rozwoju rolnictwa ekologicznego.
Thyroid hormones have an effect on every tissue of the organism because they carry out the functions of a catalyst of the oxidize reaction and the main regulator of metabolism. The thyroid hormones have an effect on the heart and cardiovascular system through β-receptors and they are synergistic with catecholamine. The excess and the deficiency of thyroid hormones in an organism is a cause of disorders in the cardiovascular system. These disorders are demonstrated as strong and nagging signs in animals and humans with hyperthyroidism and hypothyroidism. The disorders of heart functioning in hyperthyroidism may result in congestive heart failure (CHF). The development of heart failure in hyperthyroidism is connected with multidirectional changes in the cardiovascular system.
The aim of the study was to determine the characteristic clinical symptoms and discuss the laboratory results in correlation with histopathology test results in dogs having blood detected in the peritoneal cavity. The examinations were performed on 11 individuals in whom diagnostic abdominal punctures had revealed blood in peritoneal cavity. All the dogs were subjected to clinical examination, morphological and biochemical blood tests, abdominal USG and peritoneal cavity fluid examination. Seven out of the 11 dogs were put to sleep and autopsy was carried out. Diagnostic laparoscopy was performed on 4 dogs. Clinical examinations in all the dogs revealed pale mucous membranes, prolonged capillary filling time, muffled heart sounds, accelerated pulse. Laboratory blood tests showed a decrease in hematocrite, hemoglobin and albumin values. USG diagnoses confirmed the presence of fluid in the peritoneal cavity of all the dogs. Cytological examination of the peritoneal cavity fluid sediment smears demonstrated the presence of adenocarcinoma cells in 2 cases, and cancer cells in one case. The results of the histopathology examination of the malignant tumors in these 2 dogs facilitated the diagnosis of colon adenocarcinoma and ovary cancer in one of the dogs. As far as the benign tumors were concerned cavernous angioma of the liver was diagnosed in one dog and spleen angioma in 3 dogs. In the remaining 4 dogs the reason for bleeding into peritoneal cavity was liver and spleen hematomas. Determining the hematocrite value in the abdominal fluid and peripheral blood which facilitated distinguishing acute bleeding from chronic bleeding was a clinically significant examination allowing perceiving a differentiation within the peritoneal cavity fluid.
The aim of the study was to determine the effectiveness of total protein (AFTP), serum-ascites total protein gradient, and serum-ascites albumin gradient (SAAG) determination for the diagnostics of ascites in dogs. The examinations were conducted on 68 dogs of both sexes and different breeds, aged 5 months to 12 years, manifesting signs of ascites. All the animals underwent ECG, abdominal USG, blood testing (total protein, albumin). The concentration of total protein, albumin and leukocyte count was additionally determined in the ascites fluid. On the basis of the obtained results the dogs were divided into 3 groups depending on the disease etiology: group 1 - 38 dogs with the signs of ascites connected with cardiac insufficiency, group 2 - 23 dogs with the signs of ascites connected with neoplastic diseases, group 3 - 7 dogs with the signs of ascites connected with liver parenchyma pathology. The statistical analysis of the obtained results showed statistically significant differences between 3 examined groups in total protein concentration in ascites fluid (p=0.001), serum-ascites total protein gradient (p=0.003) and serum-ascites albumin gradient (p=0.0027). The determination of the serum-ascites total protein gradient and serum-ascites albumin gradient is a useful diagnostic test in the diversification of transudes and exudates. The serum-ascites total protein gradient and serum-ascites albumin gradient is significantly lower in the group of dogs with liver disease than in the group with cardiac insufficiency and neoplastic diseases. The serum-ascites albumin gradient is useful as a marker for portal hypertension.
