The incidence of thyroid dysfunction in the area of central Bosnia with special reference to hyperthyroidism was being monitored. Considering that there were disagreements among earlier authors and even their contradictory results, the goal was to determine the percentage ratio between the thyroid hyperfunction and other dysfunctions and to identify the degree of correlation between thyroid hormones and the age structure of women. The study included 76 women aged 20 to 82 years with increased values of thyroid hormones and 49 women with reduced values of thyroid hormones. Thirty female patients with baseline thyroid hormone levels comprised a control group. Hyperthyroidism was observed in 60.8 % of women, with the highest percentage of getting ill in their fourth and fifth decade of life (64 %). The monitoring of TSH, FT4 and FT3 hormone values in thyroid dysfunction compared to women with thyroid gland hormone reference values by age groups showed that there was a statistically significant difference in the age group between 40 and 59 years (p < 0.05). For the age group of 60 years and older, there was no significant difference (p > 0.05). The TSH hormone value and the age of women are positively correlated and mutually dependent (p < 0.05). The observed reduction in the thyroid hormone values with an increase in women’s age can be considered an adaptation of the organism to the reduced need for energy and represents an important metabolic parameter of the biological process of aging.

Total number and types of hemocytes were analysed in hemolymph of Roman snail (Helix pomatia L.). Significant differences in the number and types of hemocytes during the season at different locations were identified. The average number of hemocytes ranged from 154 to 288 per 10 μL of hemolymph. The highest number of hemocytes was recorded in snails at higher altitudes. Significant intergroup differences between all sites were identified. The most numerous hemocytes were granulocytes, followed by agranulocytes, while hyalinocytes were the least common in the post-hibernation period. Post hoc analysis showed certain intragroup differences for most locations except for comparison between wet habitat and habitats with anthropogenic influence, and between wet habitats and urban place with wet vegetation. A large number of transformed hemocytes in the encapsulated phase were identified in snail hemolymph infected with flat worms. Our results represent the first record of data for the number of hemocytes in molluscs and the first data for hemocytes of Helix pomatia. Further investigations and development of a uniform classification of hemocytes and their role in the immune response would be necessary in the future.

Zubčević, N., M. Fočak and D. Suljević, 2018. Highly specifi c hemagglutination activity of plant lectins in specifi c species: case of Fabaceae and Solanaceae. Bulg. J. Agric. Sci., 24 (3): 391–397 Lectins are carbohydrate-binding proteins present in most of the plants and in some animals. They possess the ability to agglutinate erythrocytes with known carbohydrate specifi city since they have at least one non-catalytic domain that binds reversibly specifi c monosaccharides or oligosaccharides. This study investigated the presence of lectins in the plant species of the family Fabaceae and Solanaceae. The results of our study have shown that 6 of 10 plant lectins caused agglutination, and 4 of them did not cause agglutination of human erythrocytes. Blood agglutination activity against A, B, AB and 0 groups was shown after exposing blood to lectin extracts obtained from 80% of tested plants in family Fabaceae, and 20% of tested plants in family Solanaceae. The highest degree of agglutination was obtained in Phaseolus vulgaris (+4) and the highest protein concentration was obtained in Lens esculenta within the family Fabaceae. There was no statistically signifi cant difference for protein concentration and specifi c lectin activity between two compared families (p>0.05).

Abstract The aim of this study was to analyze the values of biochemical parameters in patients with diabetic ketoacidosis and ketonuria. In this prospective comparative study conducted at the Clinical Center of the University of Sarajevo, hundred patients of both genders with diabetes mellitus were enrolled. Newly diagnosed diabetic patients with complications like acute ketoacidosis (n = 50) and ketonuria (n = 50) were included in this study and compared. The values of biochemical parameters in these patients were analyzed. We found that mean values of pH, base excess, hydrogencarbonate, sodium, glucose, urea and creatinine concentrations in patients with ketoacidosis were significantly different compared to patients with ketonuria. The values of potassium and calcium serum concentrations were not significantly different. Also, values of pH, base excess, as well as concentrations of hydrogencarbonate, sodium, potassium, calcium, glucose, urea and creatinine were not significantly different between male and female patients with diabetic ketoacidosis. In patients with diabetic ketonuria we found a correlation between admission glucose concentration and acid-base balance.

Peripheral blood and haematopoiesis in bone marrow and liver tissue were investigated in Bufo bufo during the sexual cycle. A combined touch and imprinting tissue method were applied for the haematopoietic cell isolation. The liver is the primary site of erythropoiesis and partial lymphopoiesis. There was a positive correlation between body mass and liver mass, but it was not significant (P > 0.05). The primary role of yellow bone marrow is the maturation of haematopoietic cells, while red bone marrow is responsible for the production of blood cells. The largest surface, and therefore the largest dimensions, was established for erythrocytes. Significant differences in the number of leukocytes and their size were established between males and females (P < 0.05). Small numbers of leukocytes but very large cells were characteristic for females. The highest percentages of leukocytes were for lymphocytes and eosinophils. The reproductive period showed significant impact on the haematopoietic intensity in the bone marrow and liver, resulting in changes in peripheral blood, regarding the ratio of mature blood cells.

Several haematological parameters in Herzegovinian donkeys based on gender and age were analysed in this study. The study included 30 clinically healthy donkeys (12 males and 18 females), between one and twenty years of age. Donkeys were grouped in three age classes: young (1-2 years, n=10), adult (3-6 years, n=12) and old donkeys (7-20 years, n=8). A total of seven haematological parameters were analysed. In both genders and in all age groups, the mean values of MCHC were slightly above the recommended reference intervals for donkeys in general. The mean values of HCT in females and in adult donkeys were lower than the reference intervals. The PLT mean values in female, and in young and old Herzegovinian donkeys were lower than the reference intervals. Gender significantly affected HCT and Hb values (p=0.049; p=0.046, respectively), which were significantly higher in males. Age significantly affected WBC and LYM count, which were lowest in young donkeys.

Trivalent chromium is an essential trace element for humans and animals and it is the final product of hexavalent chromium reduction in the cell. It is an integral part of the glucose-tolerance factor, which increases the systemic impact of insulin. The aim of this study was to analyse the effect of trivalent and hexavalent chromium on selected biochemical parameters in Japanese quails. Birds were divided into three groups: group I (control group, n=12), group II (treated with trivalent chromium, n=12) and group III (treated with hexavalent chromium, n=12). During 20 days of follow-up, control and experimental groups of quails had identical diet; chromium was added daily into the food (5 mg/kg) and water (5 mg/L) of the experimental groups. Glucose concentrations were the highest in Group III, while lowest glucose concentrations were obtained in Group I. There were higher differencies regarding blood biochemical parameters between control group and quails treated with Cr(VI). Our results showed that hexavalent chromium had negative effects on biochemical parameters in quails, while treatment with Cr(III) showed minor fluctuations in concentrations or activities of blood biochemical parameters.

Summary The aim of this study was to investigate the prognostic significance of troponin I, C-reactive protein and risk factors for the occurrence of complications after myocardial infarction. Troponin I and C-reactive protein values were analyzed in 38% of patients with complications (postinfarction angina, ventricular fibrillation, heart failure and fatal outcome) and in 62% of patients without complications. Values wererecorded on admission and between the eighth and tenth day of hospitalization. It was found that a larger number of risk factors (p = 0.00), diabetes mellitus (p = 0.02) and smoking (p = 0.01) were significantly associated with the complications. It was shown that hypertension increases the risk of developing heart failure after acute myocardial infarction (p = 0.02). It resulted with statistically non-significant difference in the observed values of troponin I between the group of patients with complications and the group without them (p = 0.22, p = 0.327). There was a statistically significant difference in the observed values of C-reactive protein in the two groups of patients (p = 0.00, p = 0.01). It can be concluded that the values of troponin I had no prognostic significance in risk stratification, while the values of C-reactive protein, individual risk factors and a large numberof risk factors hadsignificance in risk stratification after myocardial infarction.

Abstract Urinary tract infections can be uncomfortable, painful and even dangerous for most dog breeds. Clinical signs are often nonspecific and insufficient for diagnosis. Urinalysis in combination with biochemical parameters and urine culture is the best combination of clinical findings for diagnosis of urinary tract infections. The incidence of urinary tract infections in dogs population is growing and 27% of dogs develop an urinary tract infection through their life. Urinary infections occur more often in the elderly than in younger dogs. More than 70% of all urinary tract infections are infections with one bacterial species. Biochemical profile is important aspect for diagnosis establishment, but due to the nature of action infection by different agents may be considered as individual case. The main aim of this research was to analyse biochemical parameters of Maltese and Belgian Shepherd (Malinois) dog breed, who were affected by urinary tract infections. Urea concentration was elevated in Malinois, while urea, phosphates, albumins and alkaline phosphatase activity were elevated in Maltese dogs. Statistical analysis showed differences in concentrations of urea, creatinine, phosphates, so as alanine aminotransferase, alkaline phosphatase and amylase activity between compared breeds during acute urinary infections. Maltese dogs are less resistant to bacterias, that causes urinary tract infections, and have lower chance to maintain homeostasis of biochemical parameters in blood during urinary bacterial infections, in comparison to Maltese dogs.

Abstract Adaptation mechanisms as response to water content, oxygen level and pollutants are very important and they can be interpreted by hematological analysis. The aim of this study was the analysis of hematological and immune adaptations of common carp (Cyprinus carpio Linnaeus, 1758) to thermal stress. All specimens were divided into a control and experimental group. The control group of fish was exposed to a constant water temperature of 10°C. We induced thermal stress in experimental fish by gradually heating water to 28°C, held for 30 minutes and then comparing the obtained results with the control fish. Short-term hyperthermia lead to an increase of the number of leukocytes, especially pseudoeosinophilic granulocytes and monocytes, while the number of neutrophils and lymphocytes was reduced. The analysis of the leukocyte number and differential blood count in the control group showed high individual variation of segmented granulocytes, monocytes and pseudoeosinophilic granulocytes. Statistically significant differences (p=0.00) were found for the white blood cells, nonsegmented neutrophils and pseudoeosinophils between the control and experimental group. The experimental group of males had an increased number of white blood cells, monocytes and pseudoeosinophils, where significant differences were found for nonsegmented and total neutrophils and also for pseudoeosinophils (p=0.00), lymphocytes (p=0.01) and monocytes (p=0.03). Females had an increased total number of white blood cells, lymphocytes, monocytes and pseudoeosinophils, while significant differences (p=0.00) were obtained in the number of white blood cells, nonsegmented and total neutrophils and pseudoeosinophils between the control and experimental group. Adaptation mechanisms in carp after water temperature heating are mostly reflected in the increase of pseudoeosinophils and the decrease of neutrophils.

This research provides the first data on the morphological identification of the leukopoietic lineages (leukopoies) in the bone marrow of the Wistar rats. Seven types of cells were identified: myeloblasts, promyelocytes, myelocytes (neutrophils, eosinophils and basophils), metamyelocytes and band granulocytes. It was necessary to apply standard staining by using Pappenheim and cytochemical peroxidase method protocol for the proper cellular identification. Because of the consistency of the tissue, bone marrow isolation is not possible by the standard methods, it is only possible by the use of the touch technique. Mature neutrophils had high prevalence in the bone marrow, followed by the neutrophilic myelocytes. The largest among observed cells were the myeloblasts and promyelocytes. Identified cells showed great resemblance to human bone marrow cells, which is very important for any future experimental research.

Abstract Plant lectins are carbohydrate binding proteins or phytohaemagglutinins present in most plants, especially seeds and tubers, which include cereals, potatoes and beans. Lectins have great significance in the diet because of their involvement in gastrointestinal difficulties and erythrocyte agglutination. Blood agglutination activity against A, B, AB and O groups was shown after exposing blood to extracts obtained from 55% of tested plants, while in 45% of plants, agglutination was absent. The results of our study have shown that in humans, 40% of plant extracts exhibited activity against A, 40% of plant extracts exhibited activity against B, and 50% of plant extracts exhibited activity against AB and O groups in humans. The concentration of plant lectins depends on the part of the plant. Lectins from the seeds of certain plants cause the greatest percentage of erythrocyte agglutination, while the lowest agglutination was caused by plant bulbs and leaves. However, lectins derived from all plant species of the family Fabaceae agglutinated erythrocytes of all blood types to some extent.

Abstract Glyphosate is a pesticide that influences many blood parameters if taken orally or subcutaneously. This pesticide causes important changes in the metabolic activity which can be measured by organospecific enzyme activity such as liver aminotransferases (AST and ALT), while glucose acts as a stress, energy and metabolism indicator after acute glyphosate exposure. In this research, glyphosate was applied subcutaneously to rats, administrated each 24 hours for a 15 days period. The concentration of the applied glyphosate was 2.8 g/kg. The experimental rats were 13 weeks old. The concentration of serum glucose, the activity of lactate dehydrogenase and liver transaminases (AST and ALT) were observed as indicators of metabolic changes after treatment. It was observed that glyphosate led to a statistically significant decrease of serum glucose level. Statistically significantly increased (p<0.05) AST, ALT and LDH activities are indicators of hepatocyte damage while LDH activity demonstrates damage of other tissues.
