Early effects of high concentrations of progesterone and mifepristone A gene expression study of endometrial cancer cells (Ishikawa).

Anne Ørbo et al.

The Journal of steroid biochemistry and molecular biology, 113(1-2), 139-149 (2009-01-14)

Patients with endometrial hyperplasia representing preliminary stages of endometrial cancer have shown to respond to therapy in 100% of the cases when treated with levonorgestrel-impregnated intrauterine device. Anti-proliferative effect has also been reported after application of an anti-progestin impregnated intrauterine

Serum modifies the concentration-dependent effects that sex steroids exert on cgmp and cAMP levels, and the growth of human c4-I cells (carcinoma of the uterine cervix).

A Orbo et al.

International journal of oncology, 5(3), 619-625 (1994-09-01)

About 50% of the cases with invasive carcinoma of the uterine cervix occurs before menopause. Cyclic changes of sex steroids may therefore interfere with the ratio between extracellular levels of cGMP and cAMP (cGMP(ex)/cAMP(ex)). This ratio has been proposed as

Mechanism of death in avalanche victims.

H Stalsberg et al.

Virchows Archiv. A, Pathological anatomy and histopathology, 414(5), 415-422 (1989-01-01)

The autopsies of 12 victims from two snow avalanches in North-Norway are reported. Supportive evidence from non-autopsied and surviving victims is included. Consistent autopsy findings were prominent lung oedema, moderate cerebral oedema, extreme contraction of the left ventricle, petechiae in

Bcl-2, BAX, and apoptosis in endometrial hyperplasia after high dose gestagen therapy: a comparison of responses in patients treated with intrauterine levonorgestrel and systemic medroxyprogesterone.

Anne Beate Vereide et al.

Gynecologic oncology, 97(3), 740-750 (2005-05-12)

The aim of the study was to investigate apoptosis as a growth regulatory mechanism of gestagen in endometrial precancers and to compare differences in the apoptotic cascade after high and low dose gestagen regimens. Pre- and post-treatment paraffin-embedded endometrial hyperplasia

Relapse risk of endometrial hyperplasia after treatment with the levonorgestrel-impregnated intrauterine system or oral progestogens.

A Ørbo et al.

BJOG : an international journal of obstetrics and gynaecology, 123(9), 1512-1519 (2015-12-03)

To investigate relapse rates after the successful treatment of patients with non-atypical endometrial hyperplasia who were randomised to either a levonorgestrel-impregnated intrauterine system (LNG-IUS; Mirena(®) ) or two regimens of oral medroxyprogesterone acetate (MPA) after primary histological response.
