Abstract:
This study follows 94 patients, age 45 to 60, by controlled, random and prospective studies in time period of six months. Out of total number of patients, 53 were divided into research group and treated with hormonal therapy (2 mg of estradiol and 0,5 mg of norgestrel), 41 patients were divided into control group and treated with refemin (Cimicifuga recemosa). Results were statistically processed using Student test and ANOVA, giving us following results: use of HNL resulted with statistically significant changes--increase of heart frequency (*p<0,01), QTc-intervals (**p=0,01), increase of systolic pressure (**p=0,01), increase of diastolic pressure (**p=0,01), increase of body mass index (**p=0,01), endometrial thickness decrease (**p=0,01); use of Cimicifuge recemose resulted with statistically significant changes--increase of diastolic pressure(*p=0,01), increase of body mass index (BMI) (*p=0,01) and endometrial thickness decrease (*p=0,05). By testing research and controlled group with ANOVA test, we have determined that there is statistical difference in operating between recovered hormone therapy and Cimicifuge recemose within parameters of hearth frequency and diastolic pressure.

Menopause
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
