RESUMO

AIM: To examine the morphometric properties of the vessels forming the Willis polygon (WP) in patients with type 2 diabetes mellitus (T2DM) and hypertension (HT) and compare them with healthy individuals. MATERIAL AND METHODS: Cranial Tomography Angiography (CTA) of 168 individuals were analyzed retrospectively. The individuals included in the study were divided into four groups according to the diagnosis. Group 1 included 40 individuals who were diagnosed with HT, Group 2 included 43 individuals who were diagnosed with DM, Group 3 included 42 individuals who were diagnosed with DM and HT, and Group 4 was the control group and included 43 individuals. The diameter and length measurements of the vessels forming the WP were included in our study. RESULTS: According to the results of the Kruskal Wallis H test, in female patients statistically significant differences were detected in the diameter measurements of the right and left A1 segment of the ACA, the diameter measurement of the left A2 segment, the diameter measurements of the right and left P1 and P2 segments of the ACP, the diameter measurements of the right and left AComP. (p < 0.05), in male patients statistically significant differences were found in the diameter of the right A1 segment of the ACA, the diameter and segment length measurements of the right and left P1 segments of the ACP, of the right and left P2 diameter measurements, and segment length measurements of the left AComP (p < 0.05). CONCLUSION: We also found that the vessel diameters were similar in the HT, DM and HT+DM groups, and smaller than the control group. In addition, we think that knowing WP morphometric measurements will both guide the radio-anatomical evaluations to be made and increase the level of microanatomical knowledge in surgical treatment.

RESUMO

PURPOSE: Teratogens cause birth defects and malformations while human development is being completed. In pregnancy, urinary tract infection (UTI) is a common health problem caused by bacteria. The fluoroquinolones such as ciprofloxacin, levofloxacin, moxifloxacin, and gemifloxacin can treat various types of bacterial infections successfully. The aim of this study is to determine whether the use of ciprofloxacin during pregnancy causes oxidative stress on brain tissues of the fetus, and whether quercetin contributes to prevent this damage if stress has already occurred. MATERIALS AND METHODS: In our study, 22 young female Wistar albino rats weighing 250 g were used. Rats were mated overnight in separate plastic cages. Female rats were regarded as pregnant when a vaginal plug was observed, and these were divided into four groups of control, ciprofloxacin, quercetin, and cipro + quercetin. Two daily i.p. 20 mg/kg doses of ciprofloxacin were administered to ciprofloxacin group between 7 and 17 d of pregnancy. Throughout the study, daily (20 d) 20 mg/kg quercetin was dissolved in corn oil and administered to the quercetin group by oral gavage. Rats were fed ad libitum throughout the study. Fetuses were taken by C-section on the 20th day of pregnancy. Thereafter, the brain tissues were subjected to histological assessments and biochemical analyzes. RESULTS: The experimental groups were compared with the control group; ciprofloxacin affected fetal development, especially caused damage to neurons in brain tissue and cause hemorrhagic defects. And also, it was determined that many parameters were affected such as antioxidant parameters, enzyme levels and levels of malondialdehyde (MDA) (a marker of lipid peroxidation). Quercetin is a member of flavonoid with strong antioxidant properties, and our results indicate that the use of ciprofloxacin in pregnancy can result damage to fetal brain tissue. CONCLUSIONS: Unlike these results when some parameters are evaluated it is understood that this harmful effects suppressed by quercetin.

RESUMO

OBJECTIVE: This study was conducted to evaluate the effect of vaginal delivery and aging on anal sphincter anatomy and function. METHOD: Asymptomatic thirty women were included in this prospective study. Group 1 included 10 women (age range: 18-50) who had never been pregnant. Group 2 included 10 women (age range: 18-50) who had vaginal delivery. Group 3 included 10 women over 50 who had vaginal delivery. RESULTS: There was no statistically significant difference between the three groups in terms of resting and squeeze pressures. It was found that sphincter thickness showed statistically significant difference between the group 1 and group 3, and also group 2 and group 3. There was not statistically significant difference between the group 1 and group 2 in terms of sphincter thickness. There was a positive correlation between the age and sphincter thickness in all groups. In terms of sphincter thickness and pressure findings there was a positive correlation between the squeeze pressure and external anal sphincter thickness only in group 3. CONCLUSION: The vaginal delivery did not have a negative influence on the structure and function of the anal sphincter in asymptomatic women. However, it was found that anal sphincter thickness changed strongly in a positive manner with aging.
