17. Thrombosis in Children
Sammanfattning : Aims: The general objective was to further elucidate thromboembolic disease in children and thereby help improve the care of these patients. More specific aims were as follows: to determine what children are affected by thrombosis; to discern any gender or age differences related to thrombosis; to identify prothrombotic risk factors; to ascertain whether autoantibodies against coagulation proteins constitute a risk factor for childhood thrombosis; to study girls receiving estrogen treatment with regard to induced hemostatic changes and efficacy of the therapy; to investigate long-term effects on the hemostatic system in children subjected to heart surgery.

18. Behavioral effects of female sex steroid hormones : models of PMS and PMDD in Wistar rats
Sammanfattning : Background Animal models can be used to mimic human conditions of psychopathology, and also as pre-clinical models to evaluate candidate drugs. With hormonal treatment it is possible to produce behavior in the rat which corresponds to the mental symptoms of pre-menstrual syndrome (PMS), and pre-menstrual dysphoric disorder (PMDD). LÄS MER
19. Apoptosis, proliferation, and sex steroid receptors in endometrium and endometrial carcinoma
Sammanfattning : This thesis focuses on the involvement of apoptosis and proliferation in the mechanisms of menstruation and hormonal replacement therapy, HRT, as well as in the mechanisms of progesterone therapy in endometrial carcinoma. The aim of the first study was to investigate endometrium for 4 days before and for 2 days during menstruation. LÄS MER

Sammanfattning : During pregnancy, the basal activity is increased in both of our major stress response systems: the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. At the same time, the reactivity towards stressors is reduced. These alterations sustain maternal and fetal homeostasis, and are involved in the regulation of gestational length. LÄS MER
