Opis:
INTRODUCTION: Acute coronary syndromes (ACS) and sudden death cause most ischemic heart disease (IHD)- related deaths, which represent 1.8 million deaths per year, with similar numbers of men and women dying from coronary artery disease (CAD). It’s known that inflammation plays crucial role in atherosclerotic plaque formation and its destabilization. The purpose of this study is to evaluate of white blood cells count in its subpopulation in patients with ACS and modifiable cardiovascular risk factors – arterial hypertension and 2 type Diabetes Mellitus (DM). MATERIAL AND METHODS: In this observational cohort trial we observed of 184 patients with ACS. All patients were randomized into four groups: 1st group - 42 patients with ACS without arterial hypertension (AH) or DM; 2nd group – 56 patients with ACS and previous AH; 3rd group – 42 patients with ACS and 2 type DM; and 4th group – 44 patients with ACS and AH and DM. We studied of leukocytes count and their subpopulations in blood. RESULTS: The mean white blood cells count was significant higher in patients with ASC, compared with control group: 8.23 [6.50; 9.40] vs 5.49 [5.20; 5.70] (p<0.001). Similarly, ACS caused increase of leukocytes subpopulation count in blood. The significant higher count of white blood cells was observed in patients with ACS and co-morbidities: 2 type DM and its association with AH. In patients with ACS and previous AH we observed significant lower neutrophils count (p<0.05), but increased quantity of lymphocytes, compared with patients with ACS without co-morbidities (p<0.001). DM and its association with AH was characterized of neutrophils, lymphocytes and monocytes counts growth. CONCLUSIONS:ACS is characterized of raised white blood cells count and its population, especially in cases of association with 2 type Diabetes Mellitus.

Opis:
The present study was undertaken to contribute to the characterization of the degree of variability in baseline damage in white blood cells from control population, and to investigate how this variability is associated with external and internal factors. Altogether 170 healthy volunteers, randomly selected from the general population of the Republic of Croatia, participated in the study. Two sensitive tests: the alkaline comet assay and the chromosome aberration test were applied to study the background levels of DNA damage in their white blood cells. The results point to inter-individual differences, indicating different genome sensitivity. As revealed by both assays, the background levels of DNA damage were mostly influenced by smoking habit as well as medical exposure (especially to diagnostic X-rays). Sex and age of subjects did not significantly influence the values of DNA damage recorded in the white blood cells. Although higher levels of DNA damage were recorded in blood samples collected during winter and autumn, they were mostly influenced by medicinal exposure and smoking habit. Statistical evaluation of the data confirmed that a positive correlation exists between DNA migration and the number of long-tailed nuclei found with the comet assay and the total number of chromosome aberrations. The data obtained can serve as control values in forthcoming biomonitoring studies.

Opis:
This research was conducted from October 2018 until April 2019 in the Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. This study aims to determine the optimum potassium diformate dosage which was added to feed to increase the immune status of Pangasianodon hypophthalmus (Sauvage, 1878). The research method used is the experimental Complete Random Design (CRD) with 4 treatments and 3 replications. The treatments are A (control), B (0.3% KDF), C (0.5% KDF), and D (0.7% KDF). Observed parameters are survival rate, gross clinical signs, intestine pH levels, total leukocyte count (white blood cells), total erythrocyte count (red blood cells), and water quality. The results showed that the 0.5% KDF addition in feed is the most effective to improve immune status. This treatment also is the most effective to improve Pangasius immune status after being challenged with A. hydrophila with survival rate of 93.33%, leukocyte count 2.98×106 cells/mm3 and erythrocyte count 1.02×106 cells/mm3. Increased leukocyte count was 65.26% and erythrocyte count - 58.23%.

Opis:
The aim our study was qualitative and quantitative analysis of white blood morphometric elements of peripheral blood (determining the quantity, blood cells dimension and several hematological values) in White Stork chicks. One of the aims was to indicate whether the sex relevantly influences the variety of the examined white blood indicators. White blood cells parameters of 53 White Stork chicks, with molecularly marked sex, was examined. Blood samples were collected in southern Poland (around Krapkowice town, near Opole city). Lymphocytes of White Storks (mean 37% for females and males) were identified as round cells with dark purple non-lobed, eccentrically positioned nucleus. Among the whole population we differentiated small lymphocytes: with diameters of 5.31 ± 0.65 μm in males and 5.57 ± 0.59 μm in females, and large lymphocytes with a diameter of 8.10 ± 0.66 μm and 8.28 ± 0.74 μm, respectively in females and males. Monocytes (mean 8% for female and males) were the largest leukocytes found in the blood film of White Stork, measuring 13.40 ± 0.97 μm for males and 13.09 ± 1.05 μm for females in diameter. The cytoplasm was abundant and it stained blue-gray, very often contained vacuoles. Heterophils (mean 42.7%) were the largest in granular leukocytes group. They were round and 11.14 ± 0.65 μm for males and 11.01 ± 0.48 μm for females in diameter. The nucleus of heterophils was lobed, usually with two or three lobes. The cytoplasm contained brick-red, elongated granules. Eosinophils (mean 9.44%) were round cells, with a diameter of 10.72 ± 0.49 μm and 10.97 ± 0.53 μm, respectively in males and females. The nucleus was lobed and mostly stained clear blue and contained red-orange, round or rod-shaped granules. Basophils (mean 1.84%) were round and contained dark blue granules, with average of 9.56 ± 0.78 and 9.13 ± 0.84 μm in diameter, for males and females. The nucleus was usually non-lobed. The H/L ratio was 4/4 for both sexes. No significant differences in levels and types of leukocytes between male and female juvenile storks have been observed.
Celem naszego badania była analiza jakościowa i ilościowa morfometrycznych elementów krwi obwodowej (określenie ilości, wymiarów krwinek i kilku wartości hematologicznych) u piskląt bociana białego. Jednym z celów było wskazanie, czy płeć ma istotny wpływ na różnorodność badanych wskaźników krwi białej. Zbadano parametry białokrwinkowe 53 piskląt bociana białego, z molekularnie oznaczoną płcią. Próbki krwi pobierano w południowej Polsce (okolice miasta Krapkowice, w pobliżu miasta Opola. Limfocyty bocianów białych (średnio 37% dla samic i samców) zostały zidentyfikowane, jako okrągłe komórki z ciemnofioletowym, ekscentrycznie usytuowanym jądrem. Spośród całej populacji wyodrębniliśmy małe limfocyty: o średnicy 5,31 ± 0,65 μm u samców i 5,57± 0,59 μm u samic oraz limfocyty duże o średnicy 8,10 ± 0,66 μm i 8,28 ± 0,74 μm, odpowiednio u samic i samców. Monocyty (średnio 8% dla samic i samców) były największymi leukocytami znalezionymi we krwi obwodowej bociana białego, o średnicy 13,40 ± 0,97 μm u samców i 13,09 ± 1,05 μm u samic. Cytoplazma była obfita i zabarwiona na niebiesko-szaro, często zawierała wakuole. Heterofile (średnio 42,7%) były największymi krwinkami wśród granulocytów. Były okrągłe i miały średnicę 11,14 ± 0,65 μm u samców i 11,01 ± 0,48 μm u samic. Jądro heterofilów było płatowate, zwykle z dwoma lub trzema płatami. Cytoplazma zawierała ceglasto-czerwone, wydłużone ziarnistości. Eozynofile ( średnio 9,44%) były okrągłymi komórkami o średnicy 10,72 ± 0,49 μm i 10,97 ± 0,53 μm, odpowiednio u samców i samic. Jądro było płatowate i przeważnie wybarwione na jasnoniebiesko, cytoplazma zawierała czerwono-pomarańczowe, okrągłe ziarnistości. Bazofile (średnio 1,84%) były okrągłe i zawierały ciemnoniebieskie ziarnistości o średniej średnicy 9,56 ± 0,78 μm i 9,13 ± 0,84 μm u samców i samic. Współczynnik H/L wynosił 4/4 dla obu płci. Nie zaobserwowano istotnych różnic w liczbie jak i frekwencji poszczególnych rodzajów krwinek białych między młodymi bocianami płci męskiej i żeńskiej.
