Effect of mRNA COVID-19 vaccine on ovarian reserve of women of reproductive age

OBJECTIVES

To evaluate the effect of messenger ribonucleic acid (mRNA) vaccines developed for severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) on the ovarian reserve of women of reproductive age.

MATERIAL AND METHODS

This prospective study was conducted between July and December 2022 in a tertiary care hospital affiliated with a university. A total of 117 patients were included in the study. The patients were divided into two groups. The first group (n = 62) consisted of women of reproductive age who received two doses of Pfizer-BioNTech COVID-19 vaccine administered 21 days apart. The control group (n = 55) included women with the same demographic characteristics who did not plan to be vaccinated. Hormonal values and basal antral follicle count were compared between two groups.

RESULTS

The mean age of the study group was 26.3 ± 3.6 years, and the mean age of the control group was 25.4 ± 6.2 years (p = 0.332). In the vaccinated group, mean follicular stimulating hormone (FSH) on day 2 was 5.29 ± 2.28; luteinizing hormone (LH): 5.18 ± 1.3; E2: 46.43 ± 24.51; anti-Mullerian hormone (AMH): 4.17 ± 2.1; antral follicle count: 16.23 ± 8.04; right ovarian volume: 6.4 ± 1.7; left ovarian volume: 6.2 ± 2.1. FSH measured at D2 in the control group was 5.68 ± 1.89; LH: 5.22 ± 2.2; E2: 48.41 ± 27.12; AMH: 4.30 ± 1.74; number of antral follicles: 15.64 ± 9.04; right ovarian volume: 6.1 ± 1.8; left ovarian volume: 6.3 ± 1.4. There were no statistically significant differences for FSH, LH, E2, AMH, ovarian volume, and number of antral follicles on the second day of menstruation between the groups.

CONCLUSIONS

According to the results of the present study, the mRNA SARS-CoV-2 vaccine does not affect the ovarian reserve of patients.

Lateral suspension with V-NOTES for the treatment of pelvic organ prolapse with the Salman-Ketenci Gencer technique

INTRODUCTION AND HYPOTHESIS

Pelvic organ prolapse (POP) is a common morbidity and 10-20% of the patients need surgical correction. Sacrocolpopexy or sacrohysteropexy procedures are satisfactory but still difficult. Lateral suspension (LS) as a safe and simple technique has become an alternative technique recently. Vaginal natural orifice transluminal endoscopic surgery (V-NOTES) is also a new modality and LS using V-NOTES has not been performed previously and should be promising.

METHODS

This prospective observational pilot study was conducted with a total of 38 women with stage 3 and 4 POP according to the Pelvic Organ Prolapse Quantification grading system (POP-Q). Lateral suspension via V-NOTES was performed with the Salman-Ketenci Gencer technique using a mesh for POP. The preoperative and postoperative 6-month POP-Q stages together with Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) scores were recorded and compared.

RESULTS

Comparison of the preoperative and postoperative 6-month POP-Q stages of the patients were statistically significant except for the total vaginal length (p<0.01). Compared with the preoperative total and subscale scores of PISQ-12, the postoperative values were considerably improved (p<0.001).

CONCLUSIONS

With the Salman-Ketenci Gencer technique not only good anatomical but also good functional results were obtained with V-NOTES. Surgeons may focus on uterine sparing while using the Salman-Ketenci Gencer technique for apical prolapse owing to the higher rate of complications related to the colposuspension and better sexual results after the cervicosuspension.

Uterine-sparing laparoscopic lateral suspension in the treatment of pelvic organ prolapse

AIM

Apical prolapse is an important component of pelvic organ prolapse. The aim of our study was to investigate the effectiveness of laparoscopic lateral suspension (LLS) surgery, which we performed while sparing the uterus.

METHODS

LLS surgery was performed on 62 patients due to apical prolapse, preserving their uterus. The patients' pelvic organ prolapse quantification system (POP-Q) points and sexual function using pelvic organ prolapse/urinary incontinence sexual function questionnaire (PISQ-12) prior to and 12 months following the surgery were compared, and the results were evaluated.

RESULTS

The POP-Q points and PISQ-12 scores evaluating sexual function of the patients who underwent LLS were significantly improved compared to pre-operation values (p ˂ 0.001). No intraoperative complications were observed in the patients. Recurrence was observed in 6 (9.6%) of 62 total cases in post-operative follow-up. Apical prolapse was seen in two patients (3.2%), and anterior vaginal wall recurrence was observed in one patient (1.6%). Posterior vaginal wall recurrence was seen in three patients (4.8%). Pelvic pain complications were observed in four patients (6.4%) in the postoperative follow-up. Mesh erosion was not observed in any of the cases. It was observed that 5 (38%) of 13 patients with stress urinary incontinence (SUI) had improved SUI complaints after surgery. The mean operation time was 66.3 ± 12.3 min.

CONCLUSION

LLS is an effective and safe method for patients with apical prolapse who want to preserve their uterus. LLS can be applied as an alternative to the sacrocolpopexy procedure, which has risks such as potentially serious neurological and life-threatening vascular injury in the sacral region.

Uterine preserving technique in the treatment of pelvic organ prolapse: Laparoscopic pectopexy

OBJECTIVE

Apical prolapse constitutes an important part of pelvic organ prolapse. In this study, our aim was to investigate the effectiveness of laparoscopic pectopexy that we made by preserving the uterus in the surgical treatment of apical prolapse.

METHODS

A total of 36 patients with apical prolapse who wanted to preserve their uterus underwent laparoscopic rectopexy. Apical prolapse and sexual function of the patients were evaluated preoperatively and 12 months after surgery using the Pelvic Organ Prolapse Quantification (POP-Q) scale and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) sexual questionnaire form. Preoperative medical records and postoperative clinical results were recorded.

RESULTS

There were no intraoperative or postoperative complications in the patients who underwent laparoscopic pectopexy. The average duration of surgery was 48.7 ± 9.8 min. Two patients had a recurrence of apical prolapse. In the Aa, Ba, C, and D points in the POP-Q staging, significant changes were observed. Postoperative PISQ-12 scores improved significantly (p < 0.05).

CONCLUSION

Uterine-preserving laparoscopic pectopexy is a safe, feasible, and effective method for treating pelvic organ prolapse. It also improved the PISQ-12 and POP-Q scores in POP patients. Laparoscopic pectopexy may increase a surgeon's technical perspective for pelvic organ prolapse surgery.

Comparison of Unilateral and Bilateral Sacrospinous Ligament Fixation Using Minimally Invasive Anchorage

Objective The aim of this study was to determine the effectiveness of a newly developed anchoring system for unilateral sacrospinous ligament fixation (USSLF) and bilateral sacrospinous ligament fixation (BSSLF) procedures.

Material and Methods Ninety-three patients with pelvic prolapse who were treated surgically with the Anchorsure System ^® between 2013 and 2018 were included in the study. USSLF was performed in 52 patients (group 1), and BSSLF was performed in 41 patients (group 2). Pelvic organ prolapse was assessed preoperatively and 6 months postoperatively.

Results There were no significant differences between groups 1 and 2 with regard to age, parity, and demographic characteristics. Anatomical improvement rates were similar, irrespective of the type of SSLF used. No bleeding requiring blood transfusion or organ injuries occurred in any patient. Three patients in the group that received BSSLF developed small asymptomatic cystoceles (grade 1 to 2); there was no recurrence of rectoceles or enteroceles. Mild cystocele was found in 1 patient from the USSLF group. There was no significant difference between the groups with respect to the recurrence of cystocele. Recurrence of vaginal vault prolapse was found in 2 patients from the USSLF group (3.84%). There was no significant difference between the groups with regard to recurrence. Febrile morbidity, clinical outcomes, blood loss, duration of operation, intraoperative complications, and length of hospital stay were similar for the two groups.

Conclusions Unilateral and bilateral SSLF techniques produce similar clinical outcomes. USSLF and BSSLF performed using the new anchoring system are safe and effective methods to treat pelvic organ prolapse.

Evaluation of complications developing during and after transvaginal ultrasound - guided oocyte retrieval

OBJECTIVES

To investigate the complications of the oocyte retrieval procedure currently used in in vitro fertilisation.

MATERIAL AND METHODS

We examined 1.031 patients who underwent oocyte retrieval in the IVF unit of our hospital for complications developed during and after the procedure.

RESULTS

No complications developed related to sedation or general anaesthesia. Vaginal bleeding was observed in 3.1% of the patients. There was no intra-abdominal bleeding or pelvic organ injuries requiring surgery. Two patients developed pelvic abscesses. Ovarian hyperstimulation syndrome (OHSS) occurred in 1.45% of the patients. Almost all of the patients tolerated the oocyte retrieval process well. After the procedure, only 2% of the patients described their pain as severe, and 0.4% as the worst pain they had ever experienced.

CONCLUSIONS

The most common complication during oocyte retrieval is vaginal bleeding, which is largely controlled by buffer application. In conclusion, the oocyte retrieval process can be considered a safe procedure.

Does feticide shorten termination duration in second trimester pregnancy terminations?

Backround

A retrospective (case-controlled) study was conducted with the aim of identifying the effect of the use of misoprostol on termination time in patients who did and did not undergo feticide procedures in second trimester pregnancy terminations.

Methods

The sampling of the study consisted of 144 pregnant women who were diagnosed as having major fetal anomalies incompatible with life, and were recommended for termination of pregnancy. The investigation showed that feticide procedures were performed for 99 women, and feticide procedures were not performed for 45 women. Misoprostol protocol was administered for 48 hours in the termination period; whether the feticide procedure directly affected the termination duration in patients who did and did not undergo feticide was evaluated.

Results

Abortion/birth was achieved in 103 (71.5%) women during the first 48 hours. There was no significant difference between the termination duration of the misoprostol protocol among the women who did and did not undergo feticide. There was no significant difference between the termination durations and fetal biometric measurements (BPD, HC) except head diameters (p=0.020 and p=0.015).

Conclusions

The misoprostol protocol is shown to be effective and safe for the termination of pregnancies during the second trimester. Feticide has no affect on the duration of termination.

Evaluation of the effect of indomethacin and piroxicam administration before embryo transfer on pregnancy rate

AIM

The aim of this study was to evaluate the effect of non-steroidal anti-inflammatory drug (NSAID) administration before embryo transfer (ET) on pregnancy rates in women undergoing in vitro fertilization/intracytoplasmic sperm injection ET.

METHODS

Our study included 255 patients diagnosed with primary or secondary infertility caused by a male or tubal-related factor, endometriosis or unexplained factors. The patients were divided randomly into three groups. Two groups were administered oral piroxicam (10 mg capsules) or 100 mg indomethacin (rectal suppository), respectively, 1-2 h before ET. As a control, the third group did not receive any form of treatment before ET. Basal levels of follicle-stimulating hormone, luteinizing hormone, and level 17β-estradiol on the day of human chorionic gonadotropin administration, the collected and transferred number of embryos, and the number of grade A embryos obtained were determined in all patients.

RESULTS

The implantation, clinical pregnancy, and miscarriage rates of the groups were compared. The clinical pregnancy rate per ET and the implantation rate were 35.2% and 12.15% in the piroxicam group, 31.7% and 10.9% in the indomethacin group, and 32.9% and 12.5% in the control, respectively. The miscarriage rates of groups 1, 2 and 3 were 12%, 11.7% and 11.7%, respectively (P = 0.964). The differences in clinical pregnancy rates among the groups were not statistically significant (P = 0.887). There were also no significant differences in the implantation rates (P = 0.842).

CONCLUSION

These results suggest that NSAID administration before ET has no additional effect on pregnancy outcome in patients undergoing in vitro fertilization.

The relationship of urocortin-2 with insulin resistance patients having PCOS

In this study, we aimed to compare the serum urocortin-2 (UCN2) levels in women with polycystic ovary syndrome (PCOS) and healthy women. Thirty-eight patients with PCOS and 41 healthy women were included in the study whose age and BMI matched. The fasting serum glucose, insulin, free testosterone, hs-CRP and UCN2 levels of the all participants were examined. HOMA-IR formula was used in order to calculate the insulin resistance. Circulating UCN2 levels were significantly elevated in women with PCOS compared with controls (142.93 ± 59.48 versus 98.56 ± 65.01 pg/ml, p = 0.002). FBG, serum insulin, hs-CRP and HOMA-IR levels were found to be increased in women with PCOS. There was a positive correlation between UCN2 and free-testosterone in only PCOS group (r = 0.235, p = 0.027). Multivariate logistic regression analyses revealed that the odds ratio for PCOS was 2.31 for patients in the highest quartile of UCN2 compared with those in the lowest quartile (OR = 2.31, 95% CI = 1.88-2.83, p=0.021). Multiple linear regression analysis revealed that HOMA-IR, hs-CRP and free-testosterone independently predicted UCN2 levels (p < 0.05). UCN2 levels were significantly higher in PCOS cases when compared to control group. UCN2 is thought to be effective on pathophysiology of PCOS by paracrine and autocrine pathways.

Comparison of GnRH antagonist and agonist mini-dose long protocols in infertile cases undergoing controlled ovarian hyperstimulation

AIM

The purpose of the present study was to determine if there is a difference between multi-dose gonadotropin releasing hormone (GnRH) antagonist protocol and long GnRH agonist protocol.

MATERIALS AND METHODS

This retrospective study compared the data pertaining to patients chosen as per predetermined acceptance criteria, 113 of whom were administered multi-dose antagonist protocol for controlled ovarian hyperstimulation (COH) while 133 were administered long agonist protocol for COH at Suleymaniye Teaching Hospital of Obstetrics and Gynecology.

RESULTS

While cancellation rate was found to be significantly higher in antagonist group (17.7% vs 11.28%), the number of follicles > 14 mm and > 16 mm, E2 level, and the number of retrieved oocytes on the day of hCG trigger were significantly lower in the same group. However, there was no difference between fertilization rates and embryonic development rates. The pregnancy rates per transfer and per cycle were found to be 40.9% and 31.7%, respectively; in the antagonist group they were lower, though not significantly, when compared to agonist group (44.1% and 39.1%, respectively). Ongoing pregnancy rates were found to be similar between the groups.

CONCLUSION

GnRH antagonist treatment protocol has a level of efficacy similar to agonist treatment protocol in terms of pregnancy results for all groups.

Evaluation of the efficacy of transobturator tape surgery in the treatment of stress urinary incontinence using urodynamics and questionnaires

OBJECTIVE

To measure the efficiency of transobturator tape (TOT) surgery using urodynamics and questionnaires in stress urinary incontinence.

MATERIALS AND METHODS

Ninety-two patients with stress and mixed urinary incontinency who underwent TOT surgery were selected for the study. We retrospectively examined the patients' urodynamics, ultrasonography, demographic characteristics, incontinency surveys, life quality scores [incontinence impact questionnaire, (IQ-7) and urinary distress inventory (UDI-6)], diagnostic findings, Q-type test, surgical records, and complications. Patients treatment adherence, life quality scores, and urodynamics were evaluated as per the findings and complications following discharge of the patients between 12 and 36 months. Patients with a surgical history as the result of incontinence were excluded from the study.

RESULTS

Prior to surgery, 57 (61%, 95) patients had stress urinary incontinence (SUI), and 35 (38%, 05) patients had mixed urinary incontinence (MUI). During surgery, 45 (48%, 91) patients underwent extra pelvic surgical intervention. The mean follow-up time was 22.17±7.55 months. Our subjective success rate was 91%, 3 and the objective success rate was 78%, 3. In the life quality evaluation, a statistically significant improvement was found between IIQ-7 and UDI-6 scores. Parity over 4 was an important failure reason. Two (2%, 17) patients developed vaginal erosion, 2 (2%, 17) of the patients developed temporary urine retention, and 1 (1%, 08) patient developed nova urge incontinence.

CONCLUSION

Our study demonstrates that TOT surgery provides high objective and subjective success and has a positive impact on life quality. The ease of application and lower complication rate makes TOT a valuable alternative for other treatment approaches in the surgical treatment of SUI.

The effect of metamizole on ischemia/reperfusion injury in the rat ovary: An analysis of biochemistry, molecular gene expression, and histopathology

Objectives:

In this study, we investigated the effect of metamizole on ischemia/reperfusion (I/R) injury an analysis of biochemistry, molecular gene expression, and histopathology in the rat ovary of female albino Wistar rats.

Materials and Methods:

Animals were divided into four groups; control group with induced ischemia-reperfusion (IRC), ischemia-reperfusion +100 mg/kg metamizole sodium (MS) (IRM-100), ischemia-reperfusion +200 mg/kg MS (IRM-200), and healthy group applied sham operation (SG).

Results:

Myeloperoxidase (MPO) activity and gene expression increased significantly in IRC and IRM-100 group rat ovarian tissue compared with the SG group (P < 0.0001). However, MPO activity and gene expression in IRM-200 group ovarian tissue decreased significantly compared with the IRC and IRM-100 groups (P < 0.0001). Histopathologically, pronounced congestion, dilated vessels, hemorrhage, edema, degenerative cells, and neutrophil migration and adhesion to the endothelium were observed in the IRC and IRM-100 group ovarian tissues. A small number of congested dilated vessels, mild congestion, and edema were observed in the IRM-200 group, but no neutrophil migration and adhesion to the endothelium or degenerative cells.

Conclusions:

At 200 mg/kg dose metamizole prevented ovarian injury induced with I/R. This data show that metamizole can be used in the ovarian I/R injury treatment.

Retrospective analysis of factors that affect the success of single-dose methotrexate treatment in ectopic pregnancy

OBJECTIVE

Detection of factors that affect the success of single-dose methotrexate treatment in ectopic pregnancy.

MATERIALS AND METHODS

We investigated 99 patients who had been treated with single-dose methotrexate for ectopic pregnancy in our clinic between January 2009 and June 2014. Demographic, clinical, and laboratory results of possible factors that affect treatment success were retrospectively analyzed. Successfully and unsuccessfully treated patients were compared based on their pre-treatment results.

RESULTS

The success rate of single-dose methotrexate treatment was found to be 70.7%. No significant difference was found between succesfully and unsuccessfully treated patients before treatment in terms of factors such as gestational weeks, mass size, presence of yolk sac, and presence of free fluid (p=0.224, p=0.201, p=0.200, p=0.200). Serum β-hCG values in patients whose treatment was unsuccessful was found to be higher compared with the successfully treated group (mean β-hCG value of unsuccessful group: 4412±3501 mIU/mL; mean β-hCG value of successful group: 1079±942 mIU/mL; p<0.001).

CONCLUSION

Single-dose methotrexate treatment is an effective and reliable method in the treatment of ectopic pregnancy. Elevation of serum β-hCG value stands as the main prognostic factor that affects the success of single-dose methotrexate treatment.

Controlled reperfusion for different durations in the treatment of ischemia-reperfusion injury of the rat ovary: evaluation of biochemical features, molecular gene expression, and histopathology

High numbers of proinflammatory cells (PMNLs), which are carried by the blood to ischemic tissue during reperfusion, are considered responsible for inducing the inflammatory response that occurs in ischemia-reperfusion (I/R) injury. Our objective was to determine the controlled reperfusion (CR) interval duration (CRID) that would minimize the injury caused by the PMNLs that infiltrate ischemic tissue. Animal groups were divided into the following groups: Sham group, ovarian I/R group (OIR), and ovarian ischemia controlled-reperfusion groups OICR-1, OICR-2, OICR-3, OICR-4, OICR-5, OICR-6, which had their ovarian artery opened and then closed for 10, 8, 6, 4, 2, or 1 s, respectively. The results show that the COX-2 activity and the gene expression decreased while the COX-1 activity and the gene expression were found to be increased in parallel to the shortening of the period in CRID. From the histopathological examinations, the findings of hemorrhage, edema, congested vascular structures, degenerated cells, and migration and adhesion of PMNLs were scaled as follows: Sham group < OICR-6 < OICR-5 < OICR-4 < OICR-3 < OICR-2 < OICR-1. The results from the histopathological assessments were consistent with the molecular and biochemical findings. In conclusion, our findings suggest that increased COX-2 activity plays a role in I/R injury of the rat ovary, and that controlled reperfusion for 3, 2, or 1 s following 2 h of ischemia may attenuate the effects of I/R injury.

The effect of metyrosine/prednisolone combination to oophorectomy-induced osteoporosis

BACKGROUND

Osteoporosis is a chronic disease characterized by a decrease in bone mineral density (BMD) and corruption of the microarchitectural structure of bone tissue.

OBJECTIVE

It was investigated whether methylprednisolone had a favorable effect on osteoporotic bone tissue in Oophorectomy induced osteoporotic rats whose endogenous adrenaline levels are suppressed with metyrosine.

MATERIALS AND METHODS

Bone Mineral Density, number of osteoblast-osteoclast, bone osteocalcin levels and alkaline phosphatase (ALP) measurements were performed. Obtained results were compared with that of alendronate.

RESULTS

Oophorectomy induced osteoporosis was exacerbated by methylprednisolone. Alentronate prevented ovariectomised induced osteoporosis, but it couldn't prevent methylprednisolone +ovariectomised induced osteoporosis in rats.

CONCLUSION

Combined treatment with methylprednisolon and metyrosine was the best treatment for preventing osteoporosis but metyrosine alone couldn't prevent osteoporosis in ovariectomised rats.

Investigation of the effects of the chronic administration of some antihypertensive drugs on enzymatic and non-enzymatic oxidant/antioxidant parameters in rat ovarian tissue

OBJECTIVE

In this study, effects of chronic antihypertensive drug (clonidine, methyldopa, amlodipine, ramipril, and rilmenidine) treatment on antioxidant-oxidant parameters were investigated in rat ovarian tissue.

STUDY DESIGN

Chronic drug administration for 30 days and at the end, biochemical examinations (total glutathione (tGSH), glutathione peroxidase (GPO), glutathione reductase (GR), glutathione s-transferase (GST), superoxide dismutase (SOD), nitric oxide (NO), catalase (CAT), malondialdehyde (MDA), and myeloperoxidase (MPO) analyses) were performed.

RESULTS

The levels of glutathione (GSH) and NO, and the activities of GPO, GR, GST, SOD, and CAT were measured the lowest in ramiprile group. Also in ramiprile group, the level of MDA and the activity of MPO was the highest.

CONCLUSION

We divided the drugs into four groups according to their biochemical side effect potentials in ovarian tissue: (I) Drugs which have no clear negative effect on ovarian tissue: clonidine, rilmenidine; (II) Drugs which have mild negative effect on ovarian tissue: methyldopa; (III) Drugs which have moderate negative effect on ovarian tissue: amlodipine; (IV) Drugs which have severe negative effect on ovarian tissue: ramipril. These data might be useful in the selection of the least toxic antihypertensive drug in pregnant and/or normal females.

Role of adrenal gland hormones in the anti-inflammatory effect mechanism of tamoxifen, a partial antagonist for oestrogen receptors, and relation with COX levels

OBJECTIVE

There is limited study about anti-inflammatory effect mechanism of tamoxifen. We aimed to investigate the anti-inflammatory activity of tamoxifen to see whether adrenal gland hormones have roles in the anti-inflammatory effect mechanism of tamoxifen and to evaluate the relationship between anti-inflammatory activity and cyclooxygenase (COX) level.

STUDY DESIGN

Effects of tamoxifen, indomethacin and prednisolon on carrageenan-induced inflammatory paw oedema were investigated in intact and adrenalectomised rats. Also blood adrenalin and corticosterone levels and paw tissue COX levels determined biochemically.

RESULTS

Tamoxifen (5, 10 and 20 mg/kg), indomethacin (5, 10 and 20 mg/kg) and prednisolon (5 mg/kg) produced anti-inflammatory effects in intact rats, however, they could not in adrenalectomized rats. 20 mg/kg tamoxifen produced low anti-inflammatory effect. Tamoxifen and indomethacin decreased COX-2 levels in intact rats, but not in adrenalectomised rats. Tamoxifen produced anti-inflammatory effects by decreasing adrenalin levels, as indomethacin does. 20 mg/kg tamoxifen decreased corticosterone levels.

CONCLUSIONS

Tamoxifen was seen to suppress carrageenan-induced inflammation significantly. The dose of tamoxifen that decreases adrenalin levels maximally and decreases corticosterone levels minimally was found to produce the most potent anti-inflammatory effect. The reason why indomethacin is more potent in high doses may be that it decreases adrenalin levels strongly at these doses, without decreasing corticosterone levels.

Investigation of the relationship of some antihypertensive drugs with oxidant/antioxidant parameters and DNA damage on rat uterus tissue

BACKGROUND

In this study, we investigated the effects of treatment with chronic antihypertensive drugs (clonidine, methyldopa, amlodipine, ramipril and rilmenidine) on oxidant-antioxidant parameters and toxic effects on DNA in rat uterus tissue. In addition, uterus tissues were examined histopathologically.

MATERIALS AND METHODS

A total of 36 albino Wistar rats were divided into the following six groups: 0.075 mg/kg clonidine group; 100 mg/kg methyldopa group; 2 mg/kg amlodipine group; 2.5 mg/kg ramipril group; 0.5 mg/kg rilmenidine group; and the healthy group. Rats underwent chronic drug administration for 30 days and at the end, biochemical and histopathological examinations were performed. All data were subjected to one-way ANOVA test.

RESULTS

We divided these drugs into the following three groups according to their effects on rat uteri: (I) mild negative effects (clonidine), (II) moderate negative effects (rilmenidine, methyldopa) and (III) drugs which had severe negative effects (amlodipine, ramipril).

CONCLUSION

These data may help with selection of antihypertensive drugs, in order to determine which drugs have the lowest toxicity in pregnant and non-pregnant (pre-pregnancy) women.
