[Microcirculatory changes in chronic venous insufficiency].

Introduction: The venous system of lower leg can be topographically divided into two subsystems: superficial (extrafascial) and profound (subfascial). Functionally, we can divide circulation in to macrocirculation (arteries and veins) and microcirculation (arterioles, capillaries, and venules). Blood flow towards heart can be disturbed by different pathological conditions, and than chronic venous insufficiency (CVI) develops.

[Ovulation induction in women in the in vitro fertilization program].

In-vitro fertilization presents a method of assisted reproduction where fusion of two gametes (fertilization) occurs in laboratory conditions. In this way part of the process which normally happens in the fallopian tube is being imitated. By ovulation the number of follicles increases, thus increasing the number of oocytes, that is the number of embryos and at the same time increasing chance of pregnancy.
