Assessment of the effects of bean extract on axillary hair reduction.

Objective: Body hair removal plays an important role in beauty standards, particularly for women. Finding a method that is easy to use, cheap, and can be done without supervision can significantly affect long-term hair reduction and reduce the side effects of hair removal. The present study investigated the impact of a containing 20% broad bean (Vicia faba) extract cream on axillary hair removal. Materials and Methods: Twenty-five female volunteers were randomly divided into A (right axillary intervention - left axillary placebo) and B (right axillary placebo - left axillary intervention). Depending on the group, each person used a cream containing 20% broad bean extract )"The extract made from the seeds and pods of broad beans.") on one side and a placebo on the other twice a day for three months. Volunteers shaved their axillary hairs three days before each visit and took pictures of both sides on the day of the visit with a trichoscope (to check the diameter and thickness of the hairs). Results: We found a decrease in thickness on the intervention group (the axilla where a cream containing broad bean extract was applied); however, this difference was not significant between the intervention side and the placebo. In terms of the number of hairs, the difference between the two groups was significant only in the second month despite the decrease on the intervention side. Evaluation based on the personal judgment of the volunteers showed that there was a substantial difference in terms of the number of hairs (p=0.012) and thinning of hair (p=0.02). Conclusion: Our findings showed that 20% broad bean extract cream could potentially reduce axillary hair growth.

The Effect of Citrus Aurantium Vaginal Cream on Vaginal Atrophy in Postmenopausal Women: A Quasi-experimental Study.

Background: Vulvovaginal atrophy (VVA) is a common condition and a silent epidemic affecting many postmenopausal women who suffer from it in silence. This study aimed to evaluate the effect of Citrus aurantium vaginal cream on vaginal atrophy in postmenopausal women. Methods: This single-group pretest-posttest quasi-experimental study was conducted on 30 postmenopausal women who were referred to the Gynecology Clinic of Imam Khomeini Hospital in the city of Noor, Iran, from June to November 2020. Citrus aurantium vaginal cream was administered to women diagnosed with vaginal atrophy (based on subjective symptoms of atrophy, descriptive evaluation of the vagina, vaginal pH measurement, and degree of vaginal maturation determined by vaginal smear) every night in the first two weeks and every other night for the second two weeks. Data were collected using the scale of subjective symptoms of vaginal atrophy; descriptive evaluation checklist of vaginal mucosa; laboratory results registration form (vaginal maturation index, vaginal maturation value, and vaginal pH) before the intervention and two and four weeks after the intervention. Data were analyzed using SPSS software (version 24) through the analysis of variance with repeated measurements, and LSD post-hoc test. A P value less than 0.05 (P<0.05) was considered statistically significant. Results: Citrus aurantium vaginal cream improved subjective symptoms of vaginal atrophy (P<0.001), reduced the score of descriptive evaluation of vaginal mucosa (P<0.001), decreased vaginal pH (P<0.001), and increased vaginal maturity (P<0.001). Conclusions: The results showed that citrus aurantium vaginal cream could improve the symptoms of vaginal atrophy without causing serious complications. However, further studies with a control group are suggested to confirm the findings of this study.Trial Registration Number: IRCT20200215046494N.

Effects of Viola odorata syrup on sleep quality in menopausal women: a randomized, triple-blind, controlled trial.

PURPOSE: The present study aimed to assess the effects of Viola odorata syrup on the sleep quality of postmenopausal women. METHODS: This triple-blinded randomized clinical trial was conducted on menopausal women presenting to the healthcare centers in Mashhad, Iran, in 2019. The participants were selected using simple random sampling. Participants received 5 ml syrup V. odorata or placebo twice a day for 1 month. Data were collected using the Pittsburgh Sleep Quality Index. The data were analyzed using SPSS version 25. RESULTS: The 118 eligible women enrolled in the study were divided into two groups of V. odorata syrup and placebo (n = 59 each). The analysis was conducted on only 84 menopausal women (42 in each group) due to exclusions. Exclusions consisted of 12 participants who withdrew from the study due to unwillingness to cooperate, 8 who had irregular consumption of the therapeutic syrup, 6 with inaccurate completion of the questionnaire, and 8 due to lack of accessibility. The two study groups were homogenous in terms of demographic characteristics. Before the intervention, no significant difference was observed in the mean PSQI score between the two groups (9.2 ± 2.9 vs. 8.4 ± 2.5) (P = 0.18). However, a significant difference was seen in the mean PSQI score between the two groups (4.9 ± 1.9 vs. 8.1 ± 2.1, P < 0.001) after the intervention. CONCLUSIONS: The findings of this study suggest that V. odorata syrup may be a useful therapeutic agent to improve the sleep quality of menopausal women. REGISTRATION CODE: IRCT20180514039660N1.

Endovascular therapy for acute stroke with a large infarct core: A systematic review and meta-analysis.

OBJECTIVE: In this meta-analysis, we aimed to investigate the efficacy and safety of endovascular treatment (EVT) for acute ischemic stroke (AIS) patients with large core infarct. METHODS: Three online databases of Web of Science, PubMed and Scopus were systematically searched. Original studies which evaluated AIS participants with large core infarction who underwent EVT were included. R statistical software was used for statistical analyses. Effect sizes were presented with odds ratios (ORs) with their 95% confidence intervals (CIs). The effect sizes were pooled using random effects modeling. RESULTS: Including 47 studies and 15,173 patients, this meta-analysis showed that compared with medical management (MM), EVT was significantly associated with decreased odds of mortality (0.67, 95% CI: 0.51-0.87) and increased odds of favorable outcomes, including a modified Rankin Scale of 0-3 (2.36, 95% CI: 1.69-3.291) and of 0-2 (3.54, 95% CI: 1.96-6.4) in 90 days and remarkable improvement in National Institutes of Health Stroke Scale within 48 h after the procedure (3.6, 95% CI:1.32-9.79). Besides, there was a higher chance of intracranial hemorrhage (ICH) development (1.88, 95% CI: 1.32-2.68) but not symptomatic ICH (1.34, 95% CI: 0.78-2.31) in those who underwent EVT. CONCLUSION: Our study suggests that EVT might be an effective and relatively safe treatment option for the treatment of AIS patients with large vessel occlusion who have large core infarcts, although more large-scale trials are needed to consolidate the results and to make inclusion criteria and the patient selection process clearer.

A promising impact of oral administration of noscapine against imiquimod-induced psoriasis-like skin lesions.

Objective: Psoriasis is a chronic inflammatory autoimmune disease. The effectiveness of noscapine has been employed as a helpful treatment for various disorders and subjected to recent theoretical breakthroughs. Materials and Methods: Psoriasis-like lesions were induced by topical application of 5% imiquimod (IMQ) (10 mg/cm2 of skin) in male Balb/c mice and then medicated with a single oral dose of methotrexate (MET) as a positive control or daily oral treatment of noscapine (5, 15 and 45 mg/kg). In this way, skin inflammation intensity, psoriatic itchiness, psoriasis area severity index (PASI) score, ear length, thickness, and organ weight were daily measured. At the end of the study, histological and immunohistochemical and enzyme-linked immunosorbent assays (ELISA, for pro-/anti-inflammatory factors) were performed in each ear. Results: IMQ caused psoriasis-like lesions. Noscapine markedly alleviated macroscopic parameters, namely ear thickness, ear length, skin inflammation, itching, and organ weight, as well as microscopic parameters including, pathology and Ki67 and p53, and tissue immunological mediators, such as tumour necrosis factor (TNF-α), interleukin (IL)-10, transforming growth factor (TGF-ß), interferon-γ (IFN-γ), IL-6, IL-17, and IL-23p19 in the psoriatic skin in a concentration manner (p<0.05-<0.001). Conclusion: Therefore, noscapine with good pharmacological properties has considerable effects on psoriasis inflammation.

Antifungal activity of three different varieties of Capsicum annuum against clinical isolates of Candida species.

OBJECTIVE: Acquired resistance to antifungal agents is rising among Candida species. Herbal extracts including Capsicum annum extracts have biological profits, which can be employed to overcome drug resistance in fungal species. The present study investigated the efficacy of different varieties of C. annum extracts against Candida species. METHODS: Aqueous and alcoholic extracts of three different varieties of C. annum were prepared using the succulent method. Total values for compound extracts of C. annum var. cayenne, C. annum var. cayenne cultivar sabzevari, and C. annum var. cerasiforme were 43, 42, and 38 g, respectively. The clinical Candida isolates including C. albicans (n = 13), C. dubliniensis (n = 2), C. parapsilosis (n = 2), and C. tropicalis (n = 1); and reference strains of C. albicans (TIMML 1292 and TIMML 183), C. krusei (TIMML 1321), C. parapsilosis (TIMML 2201), and C. tropicalis (TIMML 731) were examined based on the M27-A3 guideline. RESULTS: Aqueous and alcoholic extracts of Capsicum annum showed a minimum inhibitory concentration (MIC) range of more than 512 µg/ml against clinical and reference strains of Candida. There was no justifiable difference between the effects of these extracts on Candida species. CONCLUSION: Both aqueous and alcoholic extracts of Capsicum annum could not exert a significant effective impact on clinical and reference strains of Candida. The difference in pepper spiciness did not show a significant role against Candida isolates. However, their possible effects might be different among other yeasts or filamentous fungi.

Effect of Tomato (Solanum lycopersicum) Extract in Patients with Primary Insomnia: A Double-blind Randomized Study.

OBJECTIVE: Insomnia is a condition that causes sleep problems, and many people suffer from it. Patients with this disorder have difficulty with beginning or continuation of sleep, so they are exhausted all day long, and their performance reduces. This study was designed to assess the efficacy of capsules that contain tomato extract in patients with primary insomnia. METHODS: In this study, 70 patients with primary insomnia were assigned to 2 groups randomly: intervention and control. The intervention group used to take tomato capsules every night for 2 weeks, and the placebo one used to take placebo capsules every night for 2 weeks. All patients used to fill out Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) questionnaires before and after the intervention. ISI and PSQI results were analyzed separately on SPSS software. RESULTS: A total of 70 patients (35 in the intervention group and 35 in the control group), including 50 females and 20 males, were studied. Female to male ratio and the rate of unemployment were significantly higher in the intervention group (in both cases P < 0.001), but there was no significant difference between the intervention and control groups in other characteristics (Age, marital status, weight, height, education; in all cases P > 0.05). At the end of the study, the amount of actual sleep had increased, and the delay in falling asleep decreased in both groups; the two groups at the end of the study were not significantly different in terms of these two variables (P > 0.05). The ISI score in both groups decreased significantly at the end of the study, and the PSQI score in both groups decreased significantly at the end of the study (In both cases, P < 0.05). The absolute value of ISI score change in the intervention group was significantly higher than the control group (P < 0.001); But the absolute value of PSQI score change was not significantly different between the two groups (P = 0.102). Most importantly, the improvement of both ISI and PSQI scores in the intervention group was significantly better than the control group (P > 0.05). CONCLUSION: This study showed that tomato capsules have sleep-inducing effects, although there was no significant difference in the amount of actual sleep, and the delay in falling sleep in the intervention group compared to the control group.

Evaluating the effect of an Iranian traditional medicine-based herbal candy on body composition and appetite in overweight and obese adults: A preliminary study.

Objective: Obesity is an important public health concern in the world. Considering the limited medications and their side effects and lack of a known effective way to reduce appetite, traditional herbs have been considered a complementary treatment for obesity. Therefore, this study was conducted to evaluate the effect of an Iranian Traditional Medicine (ITM)-based herbal candy on body composition and appetite in obese and overweight adults. Materials and Methods: In this preliminary study that conducted in nutrition clinic of Ghaem Hospital of Mashhad, participants were selected from overweight and obese people and randomly assigned to either groups. Participants in the intervention group received herbal candy which contained a combination of Portulaca oleracea, Plantago psyllium, and peanut oil, while participants in the control group received placebo candy for 8 weeks. The primary (appetite response, and weight changes) and secondary (body mass index (BMI), anthropometric parameters, blood pressure, and laboratory variables) outcomes were collected at baseline and during the intervention. Results: Fifty participants between the age of 18 and 65 years old were included in this study. Herbal candy resulted in a greater reduction in mean weight and BMI compared to placebo (p<0.001). Mean of hunger, satiety, and eating capacity indicators decreased more significantly at all three intervals (30 min after herbal candy, 1 hour after meal and 2 hours after meal) at lunch and dinner meal in the intervention group compared to the control group (p<0.05). Conclusion: A combination of produced herbal candy at a dose of 4 g (2 pcs), given half an hour before each meal for 8 weeks, can be effective in reducing weight and appetite in obese and overweight people.

Edible Herbal Medicines as an Alternative to Common Medication for Sleep Disorders: A Review Article.

Insomnia is repeated difficulty in falling asleep, maintaining sleep, or experiencing low-quality sleep, resulting in some form of daytime disturbance. Sleeping disorders cause daytime fatigue, mental confusion, and over-sensitivity due to insufficient recovery from a sound sleep. There are some drugs, such as benzodiazepines and anti-histaminic agents, which help to sleep induction and insomnia cure. However, the prolonged administration is unsuitable because of tolerance and dependence. Therefore, the researchers attempt to find new medicines with lesser adverse effects. Natural products have always been good sources for developing new therapeutics for managing diseases such as cancer,cardiovascular disease, diabetes, insomnia, and liver and renal problems. Ample research has justified the acceptable reason and relevance of the use of these herbs in the treatment of insomnia. It is worth noting that in this study, we looked into various Persian herbs in a clinical trial and in vivo to treat insomnia, such as Artemisia annua, Salvia reuterana, Viola tricolor, Passiflora incarnata, lettuce, and Capparis spinose. According to research, herb extracts and fractions, particularly n-butanol fractions with non-polar agents, impact the benzodiazepine receptors and have hypnotic properties. Also, alkaloids, glycosides, flavonoids, saponins, and tannins in practically every plant are mentioned making them the popular natural compounds to help with sleep disorders and promote calmness.

The effect of nettle vaginal cream on subjective symptoms of vaginal atrophy in postmenopausal women.

BACKGROUND AND OBJECTIVE: Vaginal atrophy is a condition where the vaginal epithelium gets thinner and includes symptoms, such as vaginal dryness, abnormal vaginal discharge, vaginal bleeding, dyspareunia, and sexual problems. Hormone therapy is associated with some problems and some women prefer herbal medicine to reduce vaginal atrophy. Considering the phytoestrogenic compounds present in the nettle, this study aimed to investigate the effect of the nettle vaginal cream on subjective symptoms of vaginal atrophy in postmenopausal women. MATERIALS AND METHODS: This triple-blind randomized placebo-controlled clinical trial study was conducted on 84 eligible postmenopausal women aged 45-60 years, who referred to comprehensive health service centers in Aliabad Katul in 2021-2022. Women eligible for the study received 5% nettle vaginal cream and placebo for 8 weeks. Subjective symptoms of vaginal atrophy were assessed before, four and eight weeks after the intervention. Data collection tools included a checklist for research unit selection, individual and midwifery characteristics questionnaire, vaginal assessment scale (VAS), vaginal pH, laboratory results of the vaginal maturation value (VMV). Data analysis was performed using SPSS software (version 21) and independent t-test, Mann-Whitney, chi-square, Two-way analysis of variance and analysis of covariance. P value less than 0.05 was considered significant. RESULTS: Subjective symptoms of vaginal atrophy decreased significantly after the intervention compared to before the intervention in both the nettle and placebo groups (p < 0.001), but in the comparison between groups four weeks and eight weeks after the intervention, the subjective symptoms of vaginal atrophy in nettle group decreased significantly (p < 0.001). In the nettle group, the scores of vaginal burning, vaginal dryness, vaginal itching and dyspareunia significantly improved after the intervention compared to before the intervention (p < 0.001). Also, in the nettle group compared to the placebo group, after the intervention, vaginal burning and vaginal dryness score (p < 0.001) and vaginal itching score (0.004) improved significantly. CONCLUSION: Based on the results of the present study, Nettle vaginal cream reduced subjective symptoms of vaginal atrophy, including vaginal burning, vaginal dryness, vaginal itching, and dyspareunia in postmenopausal women, so it is a cost-effective, available and do not have the side effects product that can be useful for menopausal women.

Peritoneal lavage with Glycyrrhiza glabra is effective in preventing peritoneal adhesion in a rat model.

BACKGROUND: Intraperitoneal adhesion formation is a significant problem following surgeries, resulting in substantial clinical and economic consequences. Glycyrrhiza glabra has several pharmacological properties consisting of anti-inflammatory, anti-microbial, anti-oxidant, anti-cancer, and immunomodulatory activities. AIM: Therefore, we aimed to investigate the impacts of G. glabra on the development of post-operative abdominal adhesion in a rat model. METHODS: Male Wistar rats weighing 200-250 g were divided into six groups (n = 8): Group 1: normal group (non-surgical), and the surgical groups including Group 2: control group received the vehicle, Group 3: G. glabra 0.5% w/v, Group 4: G. glabra 1% w/v, Group 5: G. glabra 2% w/v, and Group 6: dexamethasone, 0.4% w/v. The intra-abdominal adhesion was performed utilizing soft sterilized sandpaper on one side of the cecum, and the peritoneum was slightly washed with 2 ml of the extract or vehicle. In addition, macroscopic examination of adhesion scoring and the levels of inflammatory mediators [interferon (IFN)-γ, prostaglandin E2 (PGE2)], fibrosis markers [interleukin (IL)-4, transforming growth factor (TGF)-ꞵ], and oxidative factors [malondialdehyde (MDA), nitric oxide metabolites (NO), and reduced glutathione (GSH)] were evaluated. In vitro toxicities were also done on mouse fibroblast L929 and NIH/3T3 cell lines. RESULTS: We found higher levels of adhesion (P < 0.001), IFN-γ(P < 0.001), PGE2(P < 0.001), IL-4(P < 0.001), TGF-ß(P < 0.001), MDA(P < 0.001), and NO(P < 0.001), and lower levels of GSH(P < 0.001) in the control group. In contrast, G. glabra concentration dependent and dexamethasone alleviated the levels of adhesion (P < 0.05), inflammatory mediators (P < 0.001-0.05), fibrosis (P < 0.001-0.05), and oxidative (P < 0.001-0.05) factors, while propagating the anti-oxidant marker (P < 0.001-0.05) in comparison to the control group. Results also showed that the extract did not significantly reduce cell viability up to 300 µg/ml (P > 0.05). CONCLUSION: G. glabra could concentration-dependently mitigate peritoneal adhesion formation through its anti-inflammatory, anti-fibrosis, and anti-oxidant properties. However, further clinical investigations are required to approve that G. glabra may be a promising candidate against post-surgical adhesive complications.

The effect of oral capsule of Ocimum basilicum leaf extract on sleep quality and insomnia severity in menopausal women: A randomized clinical trial.

One of the complications of menopause is sleep disorders, which affect women's health. Ocimum basilicum contains compounds that may affect sleep. The aim of this study was to determine the effect of an oral capsule of O. basilicum leaf extract on sleep quality and the severity of insomnia in menopausal women. This triple-blind, randomized clinical trial study was performed on 60 Iranian menopausal women aged 40 to 65 years. Subjects were randomly assigned into two groups of intervention (each capsule containing 250 mg of O. basilicum extract and 250 mg Avicel) per day for 1 month and placebo. The Pittsburgh Sleep Quality and Insomnia Intensity Index were used to assess sleep quality and severity of insomnia before, 2 weeks after and 1 month after the intervention. There was no statistically significant difference in the baseline variables between the intervention and placebo groups (p > .05). The total sleep quality scores in the two groups of intervention and placebo were 6.2 ± 0.3 versus 9.3 ± 0.3 (p < .001) and 3.7 ± 0.3 versus 9.1 ± 0.3 (p = .015) 2 weeks and 1 month after the intervention, respectively. The total insomnia severity scores in the two groups of intervention and placebo were 9.0 ± 0.3 versus 12.1 ± 0.3 (p < .001) and 5.6 ± 0.5 versus 11.0 ± 0.5 (p < .001) 2 weeks and 1 month after the intervention, respectively. Consumption of O. basilicum capsules improved sleep quality and insomnia in menopausal women. This study was approved (code IR.MUMS.NURSE.REC.1398.070) by the Ethic committee of Mashhad University of Medical Sciences and registered at the Iranian Registry of Clinical Trials, with the No. IRCT20200104046001N1 in January 2020.

HPLC/MS characterization of Syzygium aromaticum L. and evaluation of its effects on peritoneal adhesion: Investigating the role of inflammatory cytokines, oxidative factors, and fibrosis and angiogenesis biomarkers.

The dried flower bud of Syzygium aromaticum L. (S. aromaticum) (Myrtaceae), cloves, have been used for their analgesic and anti-inflammatory activities. Peritoneal adhesion (PA) is the most common complication of abdominal and pelvic surgeries, which causes significant adverse effects and severe economic burden. The present study aimed to evaluate the preventive effect of S. extract (SAE) on PA formation in a rat model. Male Wistar 8-week-old rats were randomly divided into sham, control (received vehicle), and treatment (0.25%, 0.5%, and 1% w/v of SAE) groups. The adhesion and related factors were examined using the Nair scoring system and immunological and biochemical kits for the levels of inflammatory cytokines [interleukin (IL)-6 and tumor necrosis factor (TNF)-α], growth factors [transforming growth factor (TGF)-ß1 and vascular endothelial growth factor (VEGF)], oxidative [nitric oxide (NO) and malondialdehyde (MDA)], and anti-oxidative [glutathione (GSH)] factors. Our results figured out that the adhesion score and IL-6, TNF-α, TGF-ß1, VEGF, NO, and MDA levels were significantly increased, but the GSH level was decreased in the control group compared to the sham group (p < 0.001-0.05). On the other hand, the 0.25% SAE group had a lower adhesion score, and IL-6, TNF-α, TGF-ß1, VEGF, NO, and MDA levels were significantly decreased compared with the vehicle group, and the level of GSH was increased (p < 0.001-0.05). SAE could efficiently reduce adhesion score and regulate inflammatory cytokines, oxidative and anti-oxidative factors, and biomarkers of fibrosis and angiogenesis. Therefore, clove extract can be considered a potential candidate for PA management.

The effects of Artemisia absinthium L. on scopolamine-induced learning and memory impairment and brain tissue oxidative damage in adult rats.

Objective: The present study examined the effects of Artemisia absinthium L. on scopolamine-induced memory dysfunction and brain tissue oxidative damage in rats. Materials and Methods: Fifty rats were used in five groups: Control: received dimethyl sulfoxide (DMSO)/saline, Scopolamine: scopolamine (2 mg/kg) was administered along with DMSO/saline, and Scopolamine-Ext 50, Scopolamine-Ext 100, and Scopolamine-Ext 200 groups: A. absinthium hydroalcoholic extract 50, 100 and 200 mg/kg were administered before scopolamine. The Morris water maze (MWM) and passive avoidance (PA) tasks were used for assessment of behavioral parameters. Malondialdehyde (MDA), nitric oxide (NO) metabolites, total thiol, catalase (CAT), and superoxide dismutase (SOD) were measured in the cortex and hippocampus. Results: A. absinthium decreased the delay time and distance traveled to reach the platform in the MWM test (p<0.05-p<0.001). Besides, the extract increased the delay time to pass in the dark and the light time while decreasing the number of entrances and the dark time in the PA task (p<0.05-p<0.001). In biochemical assessments, A. absinthium attenuated NO metabolites (p<0.001) and MDA (p<0.05- p<0.001) while enhanced total thiol (p<0.001), CAT and SOD (both p<0.05-p<0.001). Conclusion: This study revealed that A. absinthium improved memory and learning impairment and brain tissue oxidative damage in scopolamine-treated rats.

The possible mechanism of Datura stramonium on pentobarbital-induced sleep in mice.

BACKGROUND: Insomnia leads to the development of mental problems and missing of accuracy in affected persons. Various investigations have previously revealed which medicinal plants play a role in the improvement of insomnia. In this study, we evaluated the effect of hydro-alcoholic extract of Datura stramonium on insomnia in mice. METHODS: The extracts and fractions at different concentrations were injected intraperitoneally (i.p.) to mice 30 min before the sodium pentobarbital (30 mg/kg, i.p.). Additionally, the blood was collected from cardiac and serum separated to measure brain-derived neurotrophic factor (BDNF). The LC-MS was done to identify the active components. Flumazenil or naloxone were also applied to study the possible mechanism of extract. The PC12 cells were then exposed to different doses of extract and fractions, in order to evaluate cytotoxicity by MTT assay and the measured LD50. RESULTS: The hydro-alcoholic extracts of calyx, seed and petal elevated sleep duration and decreased sleep latency. In addition, water, ethyl acetate and n-butanol fractions of hydro-alcoholic extract of petal increased sleep duration. Of note, Naloxone significantly reversed the hypnotic effect of the extract. The extract increased the level of BDNF in serums. As well, the toxicity assessment revealed that the extracts had not toxic on PC12 cells. The LD50 value was obtained as 4.8 g/kg. CONCLUSION: This research demonstrated that D. stramonium (including seed, petal and calyx) increased the hypnotic effect without neurotoxicity on PC12 cells. Sleep induction may be related to its active ingredients as well as the effect on opioid receptors.

The Effects of Urolithin B and Auraptene on Quinolinic Acid-induced Toxicity in the SH-SY5Y Neuroblastoma Cell Line.

The pathological accumulation of quinolinic acid (QA) is often associated with neuritis and neuronal cell death in several neurodegenerative diseases, through the overproduction of free radicals. Urolithin B and auraptene have been reported to exert potent antioxidant effects - however, little is known about the protective effects of these compounds against QA-induced neurotoxicity. Therefore, this study aimed to explore the in vitro protective effects of urolithin B and auraptene against QA-induced neurotoxicity in the SH-SY5Y neuroblastoma cell line. The MTT assay was used to evaluate cell viability, and flow cytometry was carried out to evaluate effects on the cell cycle and apoptosis. The intracellular levels of reactive oxygen species (ROS) were also determined. Our findings showed that auraptene at non-toxic concentrations had no protective effect on QA-induced toxicity. However, urolithin B at concentrations of 0.6 µM and 2.5 µM enhanced the viability of cells treated with QA. Moreover, while the percentage of apoptotic cells (i.e. in the sub-G1 phase) was shown to significantly increase after QA treatment, pre-treatment with urolithin B reduced the number of these apoptotic cells. Furthermore, urolithin B, as an antioxidant, also significantly reduced QA-induced ROS production. Our findings suggest that urolithin B may possess potent antioxidant and neuroprotective effects against QA-induced neurotoxicity that merit further investigation.

The Effect of Pomegranate Juice and Sumac Consumption in the Treatment of Outpatients with COVID-19.

Introduction: COVID-19, an epidemic of coronavirus infection, has become a major global threat. The coronavirus mainly targets the human respiratory system, followed by cytokine storm, and altered immune responses associated with disease progression and adverse outcomes. Sumac and pomegranate juice are rich in bioactive compounds, which potentially have antiviral activities. This study is aimed at investigating the effect of a diet based on the use of sumac and pomegranate juice on the treatment of outpatients with COVID-19. Methods: In this study, 182 outpatients with COVID-19 were randomly divided into two groups receiving a diet containing pomegranate juice and sumac along with standard treatment and the control group (group 2) receiving standard treatment. Results: Consumption of a diet containing pomegranate juice and sumac in outpatients with COVID-19, who were receiving standard-of-care treatment, led to a significant decrease in fever, chills, cough, weakness, smell and taste disorders, shortness of breath, diarrhea, nausea and vomiting, and abdominal pain compared with outpatients with COVID-19 who received only standard treatment. Conclusion: Clinical trials of outpatients have limitations such as patients' resilience to post-COVID-19 follow-up. However, the use of pomegranate juice and sumac can be efficacious in reducing COVID-19 symptoms. This trial is registered with IRCT20190406043175N3.

Neuroprotective effects of the fractions of Ocimum basilicum in seizures induced by pentylenetetrazole in mice.

Objective: Neuroprotective and antioxidant effects of Ocimum basilicum (O. basilicum) against pentylenetetrazole (PTZ)-induced seizures were investigated. Materials and Methods: Mice were divided as follows: (Group 1) Control, (Group 2) PTZ, (Groups 3-5) 50,100 and 200 mg/kg hydro-ethanolic (HE) extract, and (Groups 6-8) 200 mg/kg ethyl-acetate (EAF), N-hexane (NHF) and water (WF) fractions. Minimal clonic seizures (MCS) and generalized tonic-clonic seizures (GTCS) latencies were measured. Biochemical and histological studies were done. Results: MCS and GTCS latency in HE groups were longer than the PTZ group (p<0.05 to p<0.001). EAF and NHF prolonged the onset of MCS and GTCS (p<0.001). PTZ increased malondialdehyde (MDA) and dark neuron (DN) production while decreased thiol, catalase (CAT) and superoxide dismutase (SOD) (p<0.05 to p<0.001). Pre-treatment by HE and all fractions of the plant attenuated MDA and DN while increased thiol, CAT and SOD (p<0.01 to p<0.001). Conclusion: EAF and NHF had anticonvulsant properties. The extract and fractions protected the brain from PTZ-induced oxidative damages and showed neuroprotective effects.

Punica granatum seed oil detracts peritoneal adhesion: Perusing antioxidant, anti-inflammatory, antifibrotic, and antiangiogenic impacts.

Peritoneal adhesion is a significant problem following gastrointestinal surgeries, accompanied by a significant economic burden and morbidity for patients. Punica granatum seed oil (PSO) possesses antioxidative, anti-inflammatory, and anticancer effects. Thus, we aimed to evaluate the antiperitoneal adhesive properties of PSO in rats. Forty-eight Wistar rats (200-250 g) were randomly and equally divided into six groups: sham group, control group; peritoneal adhesion without any treatment, vehicle group; peritoneal adhesion with saline + Tween-80.5% treatment, and experimental groups; peritoneal adhesion with 0.5%, 1.5%, and 4.5% v/v PSO treatment. In addition, peritoneal adhesion was examined macroscopically along with evaluating the oxidative stress (malondialdehyde [MDA], nitric oxide [NO], and glutathione [GSH]) inflammatory (interleukin [IL]-6, IL-1ß, and tumor necrosis factor-α [TNF-α]), fibrotic (transforming growth factor-ß [TGF-ß]), and angiogenic (vascular endothelial growth factor [VEGF]) factors. Our results revealed that the levels of adhesion scores, MDA, NO, IL-6, TNF-α, IL-1ß, TGF-ß, and VEGF, were propagated in the vehicle group while the GSH level was alleviated (p < 0.001). In contrast, premedication with PSO, especially at the lowest concentration, notably lessened the levels of adhesion scores, MDA, NO, IL-6, TNF-α, IL-1ß, TGF-ß, and VEGF as well as GSH in comparison to the vehicle group following the peritoneal adhesion induction (p < 0.001-0.05). As a result, PSO may prevent peritoneal adhesion through its antioxidant, anti-inflammatory, antifibrotic, and antiangiogenic properties. Therefore, PSO could be considered a beneficial candidate for the treatment of postoperative peritoneal adhesion.
