Soluble form of the scavenger receptor for hemoglobin (sCD163) in pregnancies complicated by preterm prelabor rupture of membranes
Kacerovský, Marian ; Tošner, Jindřich (advisor) ; Calda, Pavel (referee) ; Procházka, Martin (referee)
Preterm prelabor rupture of membranes (PPROM) is responsible for approximately 30% of all preterm deliveries. Histological chorioamnionitis (HCA) has been found in 50-80% of PPROM cases and is associated with higher rates of adverse maternal and neonatal outcome. The scavenger receptor for hemoglobin (CD163) is a transmembrane glycoprotein expressed almost exclusively on monocytes and macrophages. Its main function is the binding of hemoglobin-haptoglobin complexes. CD163 also serves as a surface receptor that recognizes intact bacteria and triggers cytokine production function. Moreover, it participates in the late down-regulatory phase of both acute and chronic inflammation. The soluble form of CD163 (sCD163) most likely represents the extracellular domain of CD163, which can be shed from the surface and released into the body fluid. The main aim of this thesis was to investigate sCD163 in pregnancy complicated by PPROM and relationships with HCA and funisitis. The first specific aim was to determine amniotic fluid sCD163 levels in uncomplicated pregnancies. Amniotic fluid samples were taken from 31 women who underwent amniocentesis for genetic testing in the second trimester, as well as from 32 women at term, 21 of whom had and 11 of whom did not have uterine contractions. The sCD163 levels in...

Influence of contraceptives and hormonal substitution therapy on the receptors of sex steroid hormones
Krasulová, Hana ; Tošner, Jindřich (referee) ; Hochmann, Jiří (advisor)
The thesis deals with questions about levels of estrogen and progesteron receptors (ER and PR) in normal breast tissue and in tumorous tissue and explains their changes. The aim of our effort was to find the publications which deal with possibilities of false positivity or negativity in a breast cancer and clarify the time period after which we can expect relevant results of the receptor levels after contraception therapy or hormonal substitution therapy and which concentration of hormones we can expect in serum. First we listed contraception therapy and hormonal therapy. We focused on physiological concentrations of estradiol and progesterone in serum and their potential affection by contraception and hormonal substitution therapy. We found that most of contraceptives contain now such dose of ethinylestradiol to reach such concentration in the serum which are nearly physiological. In postmenopauzal women the estradiol levels decreases in comparison with premenopausal women. The doses of ethinylestradiol during substitution therapy are essentially higher than during contraception therapy. Subsequently we searched for the releationship between levels of ER and PR and their potential affection by contraception or hormonal substituonal therapy. As the Czech literature does not include this questions -...

Mucocutaneous candidiasis and women's sexual hormones
Košťálová, Marie ; Tošner, Jindřich (advisor) ; Kudela, Milan (referee) ; Mencl, Karel (referee)
The aim of this work was to study relationship between mucocutaneous candidiasis (MCC) and women's sexual hormones. This problem is usually solved by dermatologists, gynaecologists and mycologists separately. Our approach is original, because it is primarily based on skin and/or cutaneous appendagies affection and searches for possible coincidence or other relation in vulvovaginal region. We examined 81 women in our study and divided them into two groups according to hormone-level investigation (women in fertile and perimenopausal period, women in postmenopausal period). We also developed "Candida" questionnaire for further anamnestic data correlation. The relationship between MCC and women's sexual hormones was studied both, in vivo and in vitro. We found C. albicans in vagina in both studied groups most frequently at the time of cutaneous candidiasis. In postmenopausal period the incidence of vaginal C. albicans was significantly lower (significantly lower levels of E2, PG). The cultivation identity between skin and vulvovaginal region was more frequent in fertile and perimenopausal period than in postmenopausal one, too. Predominantely concerned C. albicans again, the conformity was considerable in women with established ovulation (significantly higher levels of PG). In presence of C. albicans in...
