Endometriosis (END) is a chronic inflammatory disorder marked by the existence of endometrial-like tissue in the abnormal sites, resulting in immunological and inflammatory dysregulation. This study was to examine the impact of resveratrol and the AhR antagonist, CH223191, on the modulation of inflammatory and immunological responses in an experimental rat model of endometriosis. Adult female rats and adult male rats were employed in the current study. The female rats were randomly divided into the following: Naïve rats, donor rats for endometrial tissue transplantation, recipient endometriotic rats, and fertile male rats utilized for fertility tests. All endometriotic rats were equally divided into four groups, as follows: END group: Rats in this group served as positive controls and received no treatments; END+RES group: Endometriotic rats received a daily oral dose of resveratrol for four weeks; END+AhR‾ group: Endometriotic rats received intraperitoneal injections of CH223191 every three days for four weeks; END+DMSO group: Endometriotic rats were given dimethyl sulfoxide (DMSO), which was utilized in the preparation of resveratrol and AhR‾ treatments intraperitoneally every three days for four weeks, while Naïve rats served as the negative control group. At the endpoint of the experiments, three female rats from each group were mated with two pre-examined fertile male rats for fertility tests. Additionally, nine female rats from each group were euthanized to collect blood for biochemical assessments, peritoneal exudates (PE) for further analysis, spleens for Tgfβ gene expression, and uterine horns for histopathological examination. Statistical analysis of collected data revealed a significant (P<0.05) reduction in the litter size in all endometriotic rats, except END+RES, in comparison with the control group. Endometriosis in END and END+DMSO rats led to significant (P<0.05) upregulation of Tgfβ gene expression in splenocytes; these conditions significantly (P<0.05) increased TGF-β levels in the circulatory system and PE of these groups. Cancer antigen (CA-125) levels in circulation and PE significantly (P<0.05) increased in all endometriotic rats in comparison with the control, except those that were treated with RES did not show statistical change from controls. Upregulated biomarkers TGF-β and CA-125 resulted in deleterious changes in the uterine histological features. In conclusion, this study found that RES could have protective influences in endometriosis pathophysiology via its canonical pathway to suppress inflammatory responses.
Background: Hypothyroidism is a decrease in the production of the thyroid hormones and leads to gland dysfunction. Ashwagandha extract was used as an ayurvedic treatment and supposed to be as antihypothyroidism agent.
Objectives: to investigate the impact of ashwagandha (Ash) extract on propylthiouracil (PTU)-induced hypothyroidism in rats.
Subjects and Methods: The rats were divided into three groups, control group, PTU (hypothyroid) group (6mg/kg/day by oral route), PTU (6mg/kg/day by oral route) +Ash (50mg/kg/day by oral route) treated group. All treatment continued for

Show MoreA significant increase in the incidence of non-O157 verotoxigenic Escherichia coli (VTEC) infections have become a serious health issues, and this situation is worsening due to the dissemination of plasmid mediated multidrug-resistant microorganisms worldwide. This study aims to investigate the presence of plasmid-mediated verotoxin gene in non-O157 E. coli. Standard microbiological techniques identified a total of 137 E. coli isolates. The plasmid was detected by Perfectprep Plasmid Mini preparation kit. These isolates were subjected to disk diffusion assay, and plasmid curing with ethidium bromide treatment. The plasmid containing isolates were subjected to a polymerase chain reaction (PCR) for investigating

Green synthesis with broccoli offers an environmentally friendly way to produce stable and biocompatible nanomaterials. In this study, Brassica oleracea aqueous extract served as both the reducing and capping agent, producing AuNPs with a characteristic surface plasmon resonance peak at 560 nm and a well-defined cubic crystalline structure confirmed by XRD. TEM analysis showed uniformly dispersed, semi-spherical nanoparticles with an average size of 7.5 ± 3.6 nm. The biosynthesized AuNPs exhibited potent antioxidant activity, achieving 91.2 % DPPH scavenging at 100 µg/

Valerian (VAL) is a popular herbal product which should be prescribed to treat insomnia and anxiety. The study was designed to investigate the presence of significant pharmacokinetic (PK) interaction between Valerian (VAL) at different concentrations on Carbamazepine (CBZ) pharmacokinetic parameters in healthy male rabbits. In an in vivo, parallel-randomized controlled trial, the rabbits in three groups "first (control), second and third" were given oral doses of CBZ (50 mg/kg), for "second and third" groups (as test groups) rabbits were given (20 and 40 mg/kg/day) of the VAL respectively, as suspensi

Show MoreThis study aimed to investigate the ability of clove and cinnamon extracts to make pathogenic multidrug-resistant (MDR) Klebsiella pneumoniae more sensitive to the host’s immune system and thereby interrupt the bacterial infection process in the rat model. Therefore, 60 Wistar male rats were used in this study. The phytochemical constituents of the plant extract were analysed using the gas chromatography-mass spectrometry (GC-MS) technique. Then, the capability of the plant extracts, as prophylactic and treatment, against K. pneumoniae in rats was studied by estimating the complete blood counts (CBCs) and the serum concentrations of interleukin-4 (IL-4) and interferon-gamma (IFN-γ) before and after the treatment. The results showed that
