Opis:: Breast cancer is the most frequently diagnosed type of cancer in women worldwide. Both the development and progression of breast cancer are related to tumour evasion of the immune system through a process called cancer immune-editing, in which regulatory lymphocytes play an important role. The infiltration of Treg cells in patients with breast cancer has been proposed as an independent unfavourable prognostic factor. In the present study, we aimed to evaluate the percentages of the Treg cell populations in the peripheral blood of patients with breast cancer with respect to progesterone receptor expression. Peripheral blood samples were collected from 27 patients with breast cancer treated in the Clinical Department of Breast Cancer and Reconstructive Surgery of the Professor Franciszek Lukaszczyk Oncological Centre, Bydgoszcz. Flow cytometry was used to evaluate the percentage of CD25+/ FOXP3+/CD127 (–/low) T cells within CD3+/CD4+ T cells. The presence of CD25+/FOXP3+/ CD127 (–/low) T cells within CD3+/ CD4+ T cells was identified in all the examined blood samples. A statistically significantly higher percentage of CD25+/FOXP3+/CD127 (–/low) T cells within CD3+/CD4+ T cells was observed in progesterone receptor (PR)-negative breast cancer patients when compared to PR-positive breast cancer patients. The observed high percentage of CD25+/FOXP3+/CD127 (–/low) T cells within CD3+/CD4+ T cells in PR (–) breast cancer patients when compared to PR (+) breast cancer patients seems to confirm the unfavourable prognostic significance of these cells in breast cancer patients. This may indicate a rationale for combining standard oncological treatment in breast cancer patients with Treg-depleting therapy

Opis:: Progestogens share one common effect: the ability to convert proliferative endometrium to its secretory form. In contrast, their biological activity is varied, depending on the chemical structure, pharmacokinetics, receptor affinity and different potency of action. Progestogens are widely used in the treatment of menstrual cycle disturbances, various gynaecological conditions, contraception and menopausal hormone therapy. The administration of progestogen in menopausal hormone therapy is essential in women with an intact uterus to protect against endometrial hyperplasia and cancer. Progestogen selection should be based on the characteristics available for each progestogen type, relying on the assessment of relative potency of action in experimental models and animal models, and on the indirect knowledge brought by studies of the clinical use of different progestogen formulations. The choice of progestogen should involve the conscious use of knowledge of its benefits, with a focus on minimizing potential side effects. Unfortunately, there are no direct clinical studies comparing the metabolic effects of different progestogens.

Opis:: In this study, the effects of isoxsuprine hydrochloride applied 14 and 15 days after insemination in Anatolian Merino Sheep on lamb yield and some blood parameters were investigated. The research was conducted during the breeding season and 54 ewes inseminated on the same day were used. The ewes were assigned to three groups. Group I: For the placebo effect, physiological saline was injected on the 14th day into half of the control group and on the 15th day into the other half after insemination (n=18). Group II: Tocolytic drug was injected on the 14th day after insemination (n=18). Grop III: Tocolytic drug was injected on the 15th day after insemination (n=18). As the tocolytic drug, isoxsuprine hydrochloride (HCl) 3 ml (Utelax, Sanovel, Türki̇ye) was used intramuscularly. The number of pregnant and viviparous ewes, single and multiple birth ewes, lambs per viviparous ewes were determined as reproductive parameters. Blood progesterone, cortisol and calcium concentration were determined. As a result, it was determined that the single application of isoxsuprine hydrochloride (3 ml) in the implantation period did not have a positive or negative effect on reproductive parameters, and did not change the blood progesterone, calcium and cortisol concentration in ewes.
