Influence of segmentation of textiles to surface wettability

katedra: KTC; přílohy: 1 CD; rozsah: 119 This diploma paper describes influence of segmentation to surface wettability. In theoretic part are mentioned basic terms.  In this work were examples of fibers and textiles examined by optic method and on these bases were determined surface characteristics and compared by published values. For examination of dynamics of wettability was used LUCIA G analyzer.   Tato diplomová práce se zabývá vlivem členitosti povrchu plošných textilních útvarů na smáčivost. V teoretické části jsou charakterizované základní pojmy týkající se dané problematiky. V této práci byli vlákna a modelové textilie podrobené optické metodě a následně na nich stanovené povrchové charakteristiky, které byli porovnané s publikovanými hodnotami.   Na studium dynamiky smáčení byl použit obrazový analyzátor LUCIA G

Changes in C-reactive protein, haptoglobin concentrations and some haematological parameters in female dogs before mating, during preg-nancy and after parturition

SUMMARY Background: Acute phase proteins (APP) are generally used as non-specific markers of inflammation in dogs. The production of APP may be triggered also by physiological factors, for example pregnancy. Objectives: The aim of our study was to compare serum concentrations of C-reactive protein (CRP) and haptoglobin (Hp) between pregnant and non-pregnant bitches. Materials and Methods: We determined serum concentrations of CRP, Hp, haematocrit (HCT), haemoglobin (HGB), erythrocytes (RBC), leukocytes (WBC) and mean corpuscular volume of erythrocytes (MCV) in a group of 25 healthy, non-pregnant bitches. From these animals we formed a subgroup of 6 pregnant bitches. Samples of blood were collected from them before mating during oestrus. Second sampling of blood was performed at days 26−30 of pregnancy and the third one between days 58 and 62 of pregnancy. The fourth, fifth and sixth samplings were performed on days 3, 18 and 33 post-parturition, respectively. Results: Examinations of healthy, non-pregnant bitches showed that concentrations of CRP reached 7.23 ± 4.65 mg/l. Before mating CRP was at the level of 3.2 ± 1.90 mg/l and abruptly increased to 27.91 ± 2.60 mg/l by the second sampling. By the third sampling, CRP decreased to 13.25 ± 4.23 mg/l. On day 3 post-parturition, CRP increased to 14.44 ± 7.92 mg/l. At fifth sampling, CRP concentration decreased to 6.58 ± 2.81 mg/l. At third sampling, Hp decreased almost to the initial level before mating. Differences in concentrations of CRP and Hp at individual samplings were significant (α = 0.05). Discussion: Our investigations showed significant changes in CRP during pregnancy with maximal values reached between days 25 and 30 of pregnancy
