- چکیده:
- چکیده انگلیسی: Objective(s): The purpose of this study was to investigate cytotoxicity and membrane toxicity effects induced by Mesobuthus eupeus venom (MEV) on the HT-29 cell line.
Materials and Methods: To determine the in vitro cytotoxicity via MTT assays, HT-29 (as cancer cell line) and Hek-293T (as normal cell) were treated through different concentrations of MEV, and cytotoxicity effects were then measured through assessment of mitochondrial membrane potential (ΔΨm), reactive oxygen species (ROS) generation, and apoptosis induction. The colony formation assay was performed to measure the antiproliferative effect of MEV on HT-29 cells. Nuclei alterations were also observed during apoptosis following DAPI staining. Besides, atomic force microscopy (AFM) was used to detect alterations in morphology and ultrastructure of the cells at a nanoscale level.
Results: According to MTT and clonogenic assays, MEV caused a significant decrease in cell viability and proliferation of HT-29 cells while it did not have any impact on normal cells and the IC50 value was found to be 10 µg/ml. Induction of apoptosis was also confirmed by flowcytometric analysis in HT-29 cells. Moreover, the results indicated that MEV had led to a suppression of proliferation and induction of apoptosis through increased ROS and depolarization of mitochondria. Furthermore, AFM imaging demonstrated apoptosis cell death after being treated with MEV in HT-29 cells.
Conclusion: This study showed that MEV had an antiproliferative effect on HT-29 cells by inducing apoptosis through the mitochondria signaling pathway. These findings suggested that MEV could be used as a promising natural remedy for cancer treatment.- انتشار مقاله: 13-03-1398

- چکیده:
- چکیده انگلیسی: Objective(s): Recognized as a distinguished environmental and global toxicant, Bisphenol A (BPA) affects the liver, which is a vital body organ, by the induction of oxidative stress. The present study was designed to investigate the protective effect of quercetin against BPA in hepatotoxicity in Wistar rats and also, the activity of mitochondrial enzymes were evaluated.
Materials and Methods: To this end, 32 male Wistar rats were divided into four groups (six rats per group), including control, BPA (250 mg/kg), BPA + quercetin (75 mg/kg), and quercetin (75 mg/kg).
Results: The BPA-induced alterations were restored in concentrations of alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) due to the quercetin treatment (75 mg/kg) (all P<0.001). While the levels of mitochondrial membrane potential (MMP), reactive oxygen species (ROS), and malondialdehyde (MDA) decreased by the quercetin treatment in the liver mitochondria (P<0.001), Catalase (CAT) and glutathione (GSH) increased (P<0.001).
Conclusion: According to the results, the potential hepatotoxicity of BPA can be prevented by quercetin, which protects the body against oxidative stress and BPA-induced biochemical toxicity. Moreover, the reproductive toxicity of BPA after environmental or occupational exposures can be potentially prohibited by quercetin.- انتشار مقاله: 19-04-1397

- چکیده:
- چکیده انگلیسی: Background and Purpose: Candida species are opportunistic fungi, capable of causing acute and chronic infections in the gastrointestinal tract, vagina, and oral mucosa, among which Candida albicans is the most important species. The Securigera securidaca L. is used as an antiseptic to treat some diseases in traditional Iranian medicine. The aim of this study was to evaluate the antimicrobial activity of S. securidaca extracts and vaginal gel against different Candida species.
Materials and Methods: Antifungal effects of different extracts and vaginal gel of S. securidaca were investigated against Candida species. By using well diffusion test, different concentrations of the collected S. securidaca extracts and vaginal gel were examined to test their antifungal activity against C. albicans, C. parapsilosis, and C. krusei.
Results: The ethanol extract and vaginal gel with the ethanol extract of S. securidaca showed the most anti-fungal activity against all three strains.
Conclusion: The S. securidaca extract had a significant inhibitory effect on the different species of Candida; however, the highest inhibitory effect was found against C. albicans. In order to treat candidiasis, more research is required to check the efficacy of this plant in this domain.

- چکیده:
- چکیده انگلیسی: Background: Drug abuse is one of the major socio-medical problems of our time with a global scope. Abusing street drugs is on the rise among adults and is considered as a public health concern. In addition, limited studies are available in this regard. The aim of this study was to investigate the frequency of street drug poisoning in the Razi Hospital of Ahvaz in Iran during 2008-2013.
Methods: This is an epidemiological cross-sectional study based on hospital information. All admitted cases with street drug poisoning were included during 2008 to 2013 (70 patients). Data were analyzed by SPSS software using descriptive statistics and Chi-square.
Results: In the current study, out of 70 cases aged 13-53 years old, the highest frequency of abusers was related to 30 years of age, and male/female ratio was 4 to 1. Among the drugs used, methamphetamine accounted for the highest rate. In this study, 55.7% of the cases needed to be admitted to the intensive care unit and 2 deaths were observed. The most common symptom among poisoned patients includes loss of consciousness and the least common symptom is respiratory distress.
Conclusion: According to the results, it can be concluded that the poisoning will be rarely fatal in case of dangerous exposure, if they are under supervision of emergency medical attentions, including the careful management of airways and respiratory failure, hypotension monitoring, seizure and impaired management of body temperature.- انتشار مقاله: 21-08-1397
