RESUMO
AIM: The authors determined the impact of antenatal counseling against exposure to environmental cigarette smoke on the prevention of reduced neonatal birth weight according to gestational age. MATERIALS AND METHODS: A cross-sectional study was conducted in pregnant women, with 77 passive smokers and 88 non-smokers. During motivational interviews, passive smoking status was monitored and additional follow-up visits were arranged to increase the knowledge regarding perinatal risks of passive smoking, including intrauterine growth restriction and low birth weight. The authors aimed to increase the woman's motivation to avoid second-hand tobacco smoke exposure. RESULTS: The demographic and clinical findings of the study groups were found considerably similar, in this context, and the authors found positive and strong correlations between the gestational age and neonatal birth weight (r = 0.80 and r = 0.76, respectively; p < 0.05). CONCLUSIONS: During antenatal care of women, regular counseling against second-hand smoke exposure may prevent negative effect of passive smoking on neonatal birth weight according to gestational age. This promising finding needs to be supported by further studies with larger sample size considering covariates relevant to passive smoking.

BACKGROUND: Familial Mediterranean Fever (FMF) is an autosomal recessive disease characterized by short lived, febrile serosae inflammatory attacks. FMF has various effects in multiple systems and organs. AIM: In the present study, our aim was to evaluate adrenal steroidogenesis in female FMF patients. PATIENTS AND METHODS: There were 71 women in the study including 41 women with FMF and 30 women as healthy control group (HC group). Of 41 FMF patients, twenty were evaluated in attack period (AP-FMF group) whereas 21 of them were evaluated in attack-free period (AFP-FMF group). In all subjects; serum free testosterone, 17-OHP levels as hormones, IL-1 beta, TNF-alpha, IL-6, IL-18 as proinflammatory cytokines, CRP, fibrinogen, white blood cell (WBC) counts, and erythrocyte sedimentation rate (ESR) as acute phase reactants were measured in samples of venous blood taken in the morning before breakfast. RESULTS: Serum 17-OHP levels in AP-FMF group and AFP-FMF group were higher than in HC group (p < 0.001). A positive correlation was detected between serum levels of 17-OHP and IL-1 beta in FMF patients (p = 0.006; r = 0.486). There was no difference between FMF patients and HC group in terms of free testosterone levels (p > 0.05). CONCLUSIONS: Our results showed an increase in 17-OHP levels in FMF patients. These results may indicate that, regardless to the attack period adrenal steroidogenesis could be affected negatively in FMF patients.

UNLABELLED: We aimed to investigate the effect of allograft amniotic membrane utilization to prevent the post-operative adhesion formation. BACKGROUND: In 24 pregnant inbreed Wistar-Albino rats, pregnancy was terminated by forming bilateral uterine horn defect via cesarean section at 20th gestational day. Rats were assigned in three groups randomly. METHODS: In the first group, abdomen closure was achieved without administration of any intra-peritoneal material following standard surgical intervention. In the second group Seprafilm was used to cover the defect at anterior horn of uterus; whereas amniotic membrane of the rat itself was used in the third group. After 3 weeks, all rats were sacrificed and re-laparotomy was performed to determine adhesions scores. RESULTS: No significant difference was found in adhesion scores between the group 1 and group 3 and also between group 2 and group 3, supporting the previous findings in the literature. CONCLUSION: We observed that direct application of allograft amniotic membrane, which is an adhesion barrier used after cesarean section, to injured surface had no effect in the prevention of adhesions (Tab. 3, Fig. 5, Ref. 28).

OBJECTIVE: Postoperative adhesions still remain as a common and serious problem leading to morbidity, mortality and economic loss. Adhesions are the major cause of postoperative intestinal obstruction, infertility, and chronic pelvic pain. In this study, we aimed to compare adhesion prevention effects of pentoxyphylline, enoxaparin and methylene blue and to investigate the effects of these agents on angiogenesis, which is suggested as an important step in wound healing, in rat a uterine horn model. MATERIAL AND METHODS: Forty female Wistar albino rats were randomized into four subgroups and underwent laparotomy. Adhesions developed following cauterization at the anti-mesenteric surfaces of both uterine horns. After 14 days, adhesions were investigated by using macroscopic, histopathological and immunohistochemical [vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), transforming growth factor (TGF-beta), platelet-derived growth factor (PDGF)] methods. RESULTS: We found that enoxaparin significantly reduced adhesion formation. Pentoxyphylline had no significant effect on adhesion formation, whereas methylene blue had a significant decreasing effect on histopathologically determined adhesion markers and it may affect angiogenesis through PDGF. CONCLUSION: Among three agents, which were intraperitoneally given by a single dose manner in order to prevent postoperative adhesions, methylene blue and enoxaparin exhibited a positive effect, while no such effect was shown with pentoxyphylline.

OBJECTIVE: Postoperative adhesions are a serious problem. In this study, we aimed to observe the effects of sorafenib in postoperative adhesions and, to examine the effects of sorafenib on tissue levels of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF). MATERIAL AND METHODS: Twenty female Wistar albino rats were randomized into two equal groups; sorafenib group (sorafenib treated) and control group; then all rats underwent laparotomy. Adhesions were developed by scalping on the anti-mesenteric surfaces of the right uterine horns. After 14 days, adhesions were investigated by using macroscopic, histopathological and immunohistochemical (for VEGF and PDGF) methods. RESULTS: The sorafenib group had lower scores of total adhesions [1 (0-2.5) vs 1.5 (1-4); p: 0.037], staining of VEGF [1 (0-1) vs 1 (1-3); p: 0.029] and PDGF [1 (0-2) vs 2 (1-3); p: 0.006], and vascular proliferation [1 (0-2) vs 2 (1-3); p: 0.038] than the control group. CONCLUSION: The findings of the present study show that sorafenib, a tyrosine kinase inhibitor, significantly reduced postoperative adhesion formation. This effect may be explained by inhibition of VEGF, PDGF, and thus vascular proliferation.

OBJECTIVE: The effects of fibrin glue (FG) and suture were investigated and compared with experimental induction in an endometriosis model. MATERIAL AND METHODS: A randomized, controlled, and double-blind study was performed with 25 adult female Wistar Albino rats. Two autologous endometrial grafts were obtained from each of the rats. The endometrial grafts were transplanted by gluing with FG on the right abdominal wall and suturing with only 5/0 prolene on the left in ten rats. Gluing+suturing and after suturing over the covering with FG of the endometrial graft were performed, respectively, on the right and left in another ten rats. Covering with FG glue of the endometrial graft was performed in another five rats. The endometriosis-like lesions and intraperitoneal adhesions were evaluated macroscopically and histopathologically. RESULTS: The mean volume (31.4 +/- 17.3), adhesion (0.8 +/- 0.7) and inflammatory reaction (1.2 +/- 0.7) score of the implants in the group using only FG were significantly lower than in the group using suture [respectively, (49.2 +/- 20.6), (2.4 +/- 0.8), (2.2 +/- 0.8)] (p < 0.05). CONCLUSIONS: Our results demonstrate the general feasibility of reproducible and reliable endometrial graft fixation with FG onto the inner abdominal surface in rats. Furthermore, several advantageous characteristics could be demonstrated such as less inflammation and fewer adhesions.

The aim of the study was to investigate maternal (hemoglobin, hematocrit, and biochemical parameters of blood and urine) and fetal parameters (number and weight of alive fetus) of preeclampsia in a rat model. Placental oxidative stress markers (protein carbonyl, malondialdehyde) and placental antioxidant values (CuZn-superoxide dismutase, glutathione peroxidase) were also measured. Preeclampsia was induced experimentally in timed-pregnant Sprague-Dawley rats by using the reduced uterine perfusion pressure (RUPP) model. Placental oxidative stress that plays a key role in the pathophysiology of placenta-related disorders, most notably preeclampsia (PE) and intrauterine growth restriction (IUGR) were demonstrated by using RUPP model. On day 14 of gestation, silver clips were placed around the aorta below the renal arteries and on the left and right uterine arcade at the ovarian artery. In the RUPP model animals (n = 15), when compared with the normotensive controls (n = 15), arterial pressure on day 19 of gestation was significantly higher in the RUPP rats (151.7 ± 17.6 mmHg) than normal pregnant rats (113.9 ± 11.4 mmHg). The RUPP rats showed a significant increase in protein excretion when compared with the normal pregnant rats (0.3 ± 0.04 vs 0.47 ± 0.07 g/dL) (p < 0.05). Associated with the hypertension in RUPP rats, placental levels of malondialdehyde (2.4 ± 0.2 vs. 1.6 ± 0.2 umol/gm tissue) and protein carbonyl (1.4 ± 0.3 vs. 0.9 ± 0.3 nmol/mg protein) were increased, while superoxid dismutase (0.03 vs 0.42 U/mg protein) and glutathione peroxidase (1.04 ± 0.31 vs 0.76 ± 0.22 U/g protein) were decreased. Pup number (6.6 ± 3.1 vs. 9.93 ± 2.0) and litter weight (17.4 ± 7.7 vs. 22.9 ± 6.7 g) were lower in the preeclamptic group. None of the complete blood counts and biochemical values other than sodium and chlorine were significantly different in preeclamptic group. Our findings suggest that the RUPP model cannot mimic severe preeclampsia; however, further studies using different settings may be helpful to obtain a preeclampsia model that is capable of successfully producing severe preeclampsia findings.
