SummarySix parameters related to the release reaction were measured simultaneously in 10 human volunteers prior to the intake of one single dose of 1 g acetylsalicylic acid and 1, 4, 5, 6 and 7 days later: ΔE5 with diluted collagen, ΔE10 with Thrombofax® and the serotonin-14C release by undiluted and diluted collagen, by Thrombofax and by bovine plasma. The duration of the inhibitory effect varied according to the test used. It was the most prolonged (through the 7th day) if serotonin-14C release by diluted collagen was measured.A systematic investigation of the platelet release reaction in women taking a combined oral contraceptive was also performed. There were no statistically significant differences from a control group. No difference in acetylsalicylic acid sensitivity, measured 24 hours after intake of 1 g of aspirin, could be demonstrated.

Background: Dysfunctional uterine bleeding is one of the most often encountered gynecologic problems causing anemia, reduced quality of life and unnecessary hysterectomies. A prospective study was conducted on women with DUB to study the effect of ormeloxifene versus combined oral contraceptive pills in controlling blood loss in them.Methods: 100 Women with DUB were enrolled randomly in three groups. After baseline assessment each patient in group A was treated with iron tablets, containing 100 mg elemental iron and folic acid 1.5 mg, for three months and were termed as control group. Group B patients were treated with ormeloxifene in dose of 60 mg twice a week for twelve weeks. Group C patients were treated with combined oral contraceptive pills for twenty- one days starting from third day of their LMP. The treatment was continued for three consecutive cycles. The efficacy of the studied drugs was analyzed by comparing the baseline and post treatment PBAC score, haemoglobin level and endometrial thickness, using appropriate statistical tests.Results: Ormeloxifene was more effective than only iron or combined oral contraceptive therapy in controlling menstrual blood loss (79.11% versus 58.57%). There was a reduction in endometrial thickness in group receiving ormeloxifene as well as in the group receiving combined oral contraceptive pills (p=0.486), however this was statistically not significant.Conclusions: Ormeloxifene was significantly better than combined OCP in reduction of menstrual blood flow in cases of DUB. It has better compliance and marked improvement in subjective symptoms as compared to OCP.

Background. Autophagy is likely altered in patients with endometriosis. Ovarian steroid hormones seem to affect this changing of the autophagic process. Objective. To study the effect of combined oral contraceptive (COC) pills on the expression of autophagic-related gene BECN1 and LC3B in the ectopic and eutopic endometria of patients with endometriosis. Material and Methods. The present quasiexperimental study recruited 36 women (18–45 years old) with endometrioma and nonendometrioma who were scheduled for surgery. Patients with endometrioma were randomly assigned to either a no-treatment group ( n = 12 ) or a COC group ( n = 12 ). The COC group was prescribed a daily oral pill composed of 3 mg drospirenone and 0.03 mg ethinyl estradiol for 6 weeks before surgery. The control group ( n = 12 ) was composed of women without endometrioma. Ectopic endometriotic and endometrium tissues were collected from the no-treatment and COC groups, whereas the only endometrium was collected from the control group. These tissues were used for real-time PCR to measure the expression of the BECN1 and LC3B genes. Results. The baseline demographic data were not different among the three groups. The BECN1 gene expression in endometrium tissue in the COC group was significantly less than that in the no-treatment and control groups ( P = 0.011 and 0.029, respectively). No significant difference of endometriotic cyst BECN1 and LC3B gene expression was found between COC and no treatment. Conclusions. Oral COC pills for 6 weeks continuously before surgery decreased the eutopic endometrial expression (mRNA) of the BECN1 gene compared to those from healthy normal women and nontreated patients with an endometriotic cyst. The change in the expression of autophagy-related genes was more distinct in eutopic than ectopic endometria. This trial is registered with TCTR20170720002. Registered and enrolled the first patient on 20 July 2017.

SummaryThe differences among human, rabbit and guinea-pig platelet adhesiveness as for inhibitions by adenosine, dipyridamole, chlorpromazine and acetylsalicylic acid are described, and the influence of measurement conditions on platelet adhesiveness is also reported. Platelet adhesiveness of human and animal species decreased with an increase of heparin concentrations and an increase of flow rate of blood passing through a glass bead column. Human and rabbit platelet adhesiveness was inhibited in vitro by adenosine, dipyridamole and chlorpromazine, but not by acetylsalicylic acid. On the other hand, guinea-pig platelet adhesiveness was inhibited by the four drugs including acetylsalicylic acid. In in vivo study, adenosine, dipyridamole and chlorpromazine inhibited platelet adhesiveness in rabbits and guinea-pigs. Acetylsalicylic acid showed the inhibitory effect in guinea-pigs, but not in rabbits.

Abstract. It has been suggested that treatment of intact male rats with oestradiol benzoate (OeB) causes an interference with testosterone (T) production by the testes by a direct inhibitory effect on steroidogenesis. To test this hypothesis, different doses (5, 10 or 25 IU) of hCG were administered concomitantly with 50 μg of OeB to adult intact or hypophysectomized male rats. The testicular and plasma testosterone, and serum hCG levels were determined. The sex accessory weights were recorded. In the intact OeB-treated group of animals, hCG stimulated both the secondary sex organs and plasma testosterone levels above the intact control group. However, in hypophysectomized animals, although plasma testosterone levels increased above that of intact controls, their secondary sex organ weights did not. Moreover, inspite of high circulating hCG levels, the testicular testosterone content and concentration remained suppressed in OeB-treated animals. The reason for such dichotomy of hCG action on OeB-treated animals is not clear at present.

Androgen-dependent dermopathy, as well as premenstrual syndrome of varying severity in young women, can cause emotional depression, difficulties in social adaptation and even depressive disorders. The aim of the study was to study the safety and efficacy of using a combined oral contraceptive (COC) Dimia® containing 20 μg ethinyl estradiol and 3 mg drospirenone in young women, as well as its therapeutic effects in androgen-dependent dermopathy. Materials and methods. The study included 57 young women aged 23.1±2.2 years with signs of androgen-dependent dermopathy. The evaluation of the change in the character of menstrual bleeding, the anthropometric parameters (body weight, waist circumference and hips), the therapeutic effect of the drug on the symptoms of androgen-dependent dermopathy, as well as the dynamics of arterial pressure, hemoglobin level, serum iron have been studied. The psycho-emotional state was assessed using the SAN questionnaire (well-being-activity-mood). Results. During 6 months of observation, there was no significant change in the body mass index, waist circumference, and hips, and the drug did not affect the blood pressure numbers. Against the background of taking the drug, there was an increase in the parameters of iron metabolism (hemoglobin content, serum iron). After 3 months of taking the contraceptive with drospirenone, the number of patients with a complaint about the abundance of menstruation decreased more than twofold (from 22.8 to 10.5%), and after 6 months of taking the drug no patient noted the profuse nature of menstruation. Before the start of taking COC with drospirenone, 57.9% of women reported painful menstrual bleeding. Against the background of taking the contraceptive within 3 months, this complaint was stopped in all patients. Sufficient efficacy of treatment of androgen dependent dermopathy in young women with the help of a microdosed drospirenone-containing combined oral contraceptive is estimated from the dermatological acne index. The analysis of the SAN questionnaire made it possible to reveal the improvement in the psychoemotional state of patients on the background of taking the drug. The conclusion. The results obtained proved the effectiveness and safety of the microclinized COC Dimia®. The drug has no significant effect on body weight, blood pressure, provides reliable control of the cycle and a decrease in menstrual bleeding, which results in stabilization of iron metabolism in the body. Dimia® is effective in the treatment of androgen-dependent dermopathy and can be recommended to young women for starting contraception.
