Although many efforts have been made to characterize the functional properties of hazelnut constituents (mainly its oil, protein, and phenolics), those of dietary fibers (DFs) have not been elucidated yet....
Paracetamol (PAR) is an analgesic and antipyretic drug that is frequently used during pregnancy in many countries of the world. Although the fetal and maternal effects of toxic or long-term therapeutic doses used during pregnancy are known, the data on fetal effects during trimesters are insufficient. In this study, the possible effects of PAR exposure on both maternal and fetal tissues were investigated during pregnancy and in different trimester periods. Pregnant rats were exposed to different doses of PAR (low dose: 50 mg/kg and high dose: 500 mg/kg) in first trimester (1-7th days), second trimester (8-14th days) and third trimester (15-21st days) of pregnancy. On the 21st day, fetuses were removed by cesarean section under anesthesia. Maternal and fetal lung tissues samples were taken for biochemical analysis. PAR exposure decreased antioxidants levels and increased oxidative stress parameters levels in maternal and infant lung tissues. TBARS and TOS values increased compared to the control group, and it was statistically significant in all groups except the 1LD group (p <0.05). SOD, CAT, GPX, TAS, and GSH parameters decreased compared to the control group, which was statistically significant in maternal lungs (p <0.05). In infant lungs, it was also statistically significant for all groups in SOD, CAT, and TAS parameters. This experimental study demonstrates that exposure to PAR during pregnancy caused toxic damage to both maternal and fetal lung organs, especially in long-term usage during pregnancy, and in the third trimester.
Background Gabapentin is a drug commonly prescribed to adult pregnant women with neuropathic pain and epilepsy. Since the effect of antiepileptic drugs used in pregnant women with epilepsy on prenatal bone development is controversial, this study was conducted to demonstrate the toxic effects of gabapentin use during pregnancy on the skeletal system. Methods In the study, pregnant Wistar albino rats were randomly selected and divided into 5 groups (n = 4) as control and 10 mg/kg/day, 30 mg/kg/day, 60 mg/kg/day and 120 mg/kg/day gabapentin groups. The pups were subjected to double skeletal staining (DSS) and the ossification lengths and areas of the fore and hind bones of the pups were measured. Immunohistochemistry (IHC) was used to evaluate the ossification sites and the levels of alkaline phosphatase (AP) and tartrate resistant acid phosphatase (TRAP) immunoreactivity in the pups' femurs. Results: According to the results, the weights and morphometric sizes of the pups were lower than those of the control group. It was found that ossification rates in the fore and hind bones were statistically significantly lower. It was revealed that AP and TRAP intensities which is metabolic markers for bone development were reduced in the experimental groups compared to the control group. Conclusions We have shown that continuous use of gabapentin during pregnancy in rats results in lower birth weight offspring, delayed ossification in the offspring and adverse effects on bone metabolism as the dose increases.
OBJECTIVE:The aim of this study was to examine the changes on the Purkinje cells in the cerebella of male rat pups born to pregnant dams that were exposed to an electromagnetic field in the prenatal period. METHODS:The first stage of the study involved 12 Sprague-Dawley rats, 6 male and 6 female, weighing between 180 and 250 g. The female rats in the experimental group were exposed to a 900-MHz electromagnetic field for 1 h at the same time every day, and no procedure was performed on the control group. Following pregnancy, six male pups from each group were divided into experimental and control groups without any procedure on the pups. After 2 months, they were sacrificed and their cerebella were removed. Histopathologically, following routine processing and fixation procedures, the cerebella were embedded in the tissue blocks. The sections taken from these blocks were stained with cresyl violet. The Purkinje cells in the cerebella were then counted on sections using the optical dissector method on an image analysis system. RESULTS: The estimation of number of the Purkinje cells in the groups revealed more cells in rats in the control group than in the experimental group. Histopathologically, Purkinje cells exhibited a normal morphological structure in the control group, while the cells in the experimental group showed damage. CONCLUSIONS: It might be asserted that the exposure of mothers to an electromagnetic field in the prenatal period may affect the development of Purkinje cells in the pup cerebella.
Electro-acupuncture is widely used in gynecology. Adnexal torsion is an important threat to ovarian reserves in women of reproductive age. This is the first study to investigate whether electro-acupuncture is beneficial in protecting ovarian reserves in case of adnexal torsion resulting in reperfusion injury. Thirty-two female Wistar Albino rats were randomized into four groups: the first group—sham operation, the second group—torsion/detorsion model, the third group—pre-acupuncture + torsion/detorsion + post-acupuncture, and the fourth group—torsion/detorsion + post-acupuncture. The acupoints used were CV4 and bilateral SP6, Ex-CA1, Kid3, and ST36. In the third group, the acupoints were needled for two weeks before torsion, continuing for a further two weeks after torsion. In the fourth group, needling began after torsion and was maintained for two weeks. Both histological and biochemical parameters indicating ovarian reserves showed that electro-acupuncture applied to the above points exhibited an ameliorating effect on ovaries injured during ischemia/reperfusion. Electro-acupuncture may be capable of protecting against and preventing ischemia/reperfusion injury in case of ovarian torsion.
