The anterior cruciate ligament injury dependency on the menstrual cycle phase in young women
Posekaná, Pavlína ; Pešicová, Lucie (advisor) ; Havlíčková, Michaela (referee)
The aim of this diploma thesis was to summarize the topic of the anterior cruciate ligament (LCA) injury dependency on the menstrual cycle phase of young women with regular sport activity. The general part describes basic knowledge about connective tissue, LCA, issues of LCA injury and related risk situations. Large chapter is dedicated to sex hormones and menstrual and ovarian cycle, which is crucial for understanding the whole topic. The main part is focused on impact of sex hormones and hormonal contraception on connective tissue, but also on muscle and nervous tissues, which might be as well important for LCA injury incidence. Next part of the thesis consists of a questionnaire survey. 52 respondents aged 15-35 with rupture or partial rupture of LCA answered the non-standardized questionnaire compiled specially for this thesis and the results were statistically processed. 14 respondents were using hormonal contraception, remaining 38 had physiological menstrual cycle. Based on the theoretical findings we expected highest incidence of LCA injuries among women without contraception in phases of menstrual cycle with highest levels of oestrogen (10th -15th day). That was confirmed (P-value: 0,0218) as well as overall lower incidence among women using contraception (P-value: 0,0006). Expected higher...

The hypothalamic-pituitary-gonadal axis and epilepsy: mutual relationships
Čuchalová, Marcela ; Herink, Josef (advisor) ; Semecký, Vladimír (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Science Author: Marcela Čuchalová Supervisor: doc. MUDr. Josef Herink, DrSc. Title of diploma thesis: The hypothalamic - pituitary - gonadal axis and epilepsy: mutual relationships The content of the diploma thesis is an overview of the anatomy and physiology of the hypothalamic-pituitary-gonadal axis (HHG). Further chapters are devoted to the influence of epilepsy on HHG function, the effect of HHG hormones on epileptic activity itself. The effect of anti-epileptics on HHG functions will also be elucidated. The second part of the diploma thesis deals with separate chapters - catamenial epilepsy and epilepsy during pregnancy. Keywords: antiepileptic drugs, gonadotropin, hypothalamic-pituitary-gonadal axis, prolactin, sex hormones, temporal lobe epilepsy.

Selected differences in pathophysiology of cardiovascular system in women
Yang, Shiann-Guey ; Kittnar, Otomar (advisor) ; Ošťádal, Petr (referee) ; Danzig, Vilém (referee)
(summary of doctoral dissertation) It has become increasingly apparent in recent years that there are important differences of many cardiovascular disorders including ventricular tachycardias in men and women. Gender differences have been observed in the epidemiology, pathogenesis and clinical presentation of various ventricular arrhythmias. Physiological menopause occurs as a part of a woman's normal aging process being based on the natural cessation of estradiol and progesterone production by the ovaries. The dramatic fall in circulating estrogens levels at menopause impacts many tissues including cardiovascular system. Because the incidence of coronary heart disease (CHD) rises significantly after menopause, it has been hypothesized that women's CHD advantage before menopause (in comparison to men of the same age) could be due to the protective effects of estrogens. However, controversial results have been reported since early nineties until today. While some studies found reduction in the incidence of CHD and in mortality from cardiovascular diseases some other studies failed to provide any evidence for an independent role of estradiol levels in determining CHD in postmenopausal women and some studies even found positive association of endogenous estradiol with the risk of CHD among women above...
