Background: Polycystic ovary syndrome (PCOS) is a complex endocrine disorder associated with irregular menstrual cycles, hyperandrogenism, obesity, and reduced fertility. Objectives: The present study aimed to formulate herbal syrup based on Iranian traditional medicine (ITM) and evaluate its effect on the letrozole-induced PCOS model in female rats. Methods: The herbal syrup contains anise, fennel, and celery seed extracts. Five different formulations were made with different percentages of additive components. Quality control and stability tests were performed on the selected formulation. During the in vivo step, 6 groups of rats were evaluated: The control group (received carboxymethyl cellulose 1% as a vehicle) and the other 5 groups (received letrozole 1 mg/kg orally for 21 days). During 21 days, daily vaginal smears were examined to detect irregularities of the estrous cycle. After induction of PCOS, rats were orally administered with herbal syrup (1, 2, 4 mL/kg) or metformin (200 mg/kg) for 28 days. Moreover, body and ovarian weights, serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and testosterone were measured. Finally, ovarian tissues were isolated for histological examination. Results: The best formulation of the syrup contained the plant extract (totally 10%), sugar (50%), sodium benzoate (0.1%), and potassium sorbate (0.1%). Body weight was significantly increased in all groups compared to the control group, and after treatment, a significant weight reduction was seen in the metformin and 1-mL/kg dose group. Following PCOS induction, ovary weight was significantly increased, while after treatment, it showed a significant decrease. After 21 days of letrozole administration, induction of PCOS was confirmed by the irregularities in estrous cycles and an increase in testosterone and LH levels. After treatments with the syrup, LH levels significantly decreased in all groups (P < 0.05), and serum testosterone and FSH levels significantly decreased in the 2-mL/kg dose group compared to the PCOS group (P < 0.05). Estradiol and progesterone levels significantly increased in the treatment groups in a dose-dependent manner. Histological studies of metformin and herbal syrup groups exhibited normal follicular development with fewer and smaller cystic follicles compared to the PCOS group. Conclusions: The herbal syrup made from anise, fennel, and celery seed extracts improved serum levels of sex hormones, recovered the ovarian morphology in PCOS-induced rats, and can be a good candidate for further clinical trials.
背景:多囊卵巢综合征(PCOS)是一种复杂的内分泌紊乱，与月经周期不规律、雄激素过多、肥胖和生育能力下降有关。目的:制备伊朗传统药物(ITM)中草药糖浆，并评价其对来曲唑诱导的雌性大鼠多囊卵巢综合征模型的影响。方法:草药糖浆含有大茴香、茴香和芹菜籽提取物。用不同比例的添加剂组成了5种不同的配方。对所选配方进行了质量控制和稳定性试验。在体内步骤中，对6组大鼠进行评估:对照组(以1%羧甲基纤维素为载体)，其余5组(口服来曲唑1 mg/kg，连续21 d)。在21天内，每天进行阴道涂片检查，以检测发情周期的不规则性。诱导多囊卵巢综合征后，大鼠分别口服草药糖浆(1、2、4 mL/kg)或二甲双胍(200 mg/kg) 28天。测定体重、卵巢重、血清促卵泡激素(FSH)、黄体生成素(LH)、雌二醇、孕酮和睾酮。最后，分离卵巢组织进行组织学检查。结果:最佳配方为植物提取物(总含量10%)、白砂糖(50%)、苯甲酸钠(0.1%)、山梨酸钾(0.1%)。与对照组相比，所有组的体重均显著增加，治疗后，二甲双胍和1 ml /kg剂量组的体重均显著减轻。PCOS诱导后卵巢重量显著增加，治疗后卵巢重量显著降低。来曲唑给药21天后，患者的排卵周期异常，睾酮和LH水平升高，证实了PCOS的诱导。治疗后各组LH水平均显著降低(P < 0.05)， 2 ml /kg剂量组血清睾酮和FSH水平均显著低于PCOS组(P < 0.05)。治疗组雌二醇和黄体酮水平呈剂量依赖性显著升高。组织学研究显示，与多囊卵巢综合征组相比，二甲双胍组和草药糖浆组的卵泡发育正常，囊泡更少、更小。结论:以八角、茴香、芹菜籽提取物为原料制备的草药糖浆可改善pcos大鼠的血清性激素水平，恢复卵巢形态，具有良好的临床应用价值。

: Since the outbreak of the COVID-19 pandemic in the last days of 2019 in China, medical experts and organizations worldwide have proposed guidelines for its prevention and treatment. However, despite the availability of state-of-the-art technologies, modern medicine specialists have so far not been successful in controlling it. This has led traditional medicine experts to propagate their knowledge to prevent and cure COVID-19, creating an open debate. According to scientific literature, traditional medicine experts claim beneficial effects of herbal medicines against viral infections and their effectiveness in controlling the symptoms of respiratory disorders. Modern medicine specialists express their concerns about the quality, safety, and efficacy of herbal medicines, in addition to the risk of herb-drug interactions and the lack of randomized clinical studies. Herbal medicines have been popular since prehistoric times, and during the COVID-19 pandemic, they are increasingly used worldwide. The lack of definite cure and the high cost of available modern medicines have also promoted the use of herbal medicines. An evidence-based approach using herbal medicines with proven antiviral activities or containing compounds providing symptomatic relief in COVID-19 can be considered for clinical studies. The interaction of herbal medicines with modern drugs should also be considered in patients taking them. Traditional and modern medicine aim to provide effective and safe treatment and prevent COVID-19 infection. Considering the ground realities of the COVID-19 crisis and keeping in view the worldwide use of herbal medicines, in our opinion, the pros and cons of their use should be carefully weighed, and practical solutions should be considered.

Background: Migraine sufferers seek a range of treatments according to the frequency and severity of their symptoms. Just a few research studies have shown the effectiveness of ginger derivatives for migraine treatment. Ginger has analgesic properties and is effective for the acute treatment of migraines, and there is anecdotal evidence of its effectiveness in migraine prevention. Objectives: The goal of this research was to see whether ginger may help prophylaxis of migraine episodes. Methods: This randomized, double-blind, placebo-controlled clinical study was done in the Neurology Clinic of Golestan Hospital (Ahvaz, Iran). This research enrolled 103 individuals with episodic migraine aged 18 to 50 years. Randomization was used to divide the participants into two groups: control and intervention. For three months, patients were given 500 mg dry extract of ginger (5% active component) or placebo (starch) tablets twice a day. At the baseline and end of the study, MIDAS score, the number and duration of migraine attacks, headache severity, demographic data, dietary intakes, and anthropometric indices were collected. The data were statistically analyzed using the SPSS (version 26). In all tests, a P < 0.05 was deemed statistically significant. Results: At the end of the study, MIDAS score, duration of migraine attacks, and headache severity decreased significantly in the ginger group compared to the placebo group (P < 0.05). Furthermore, there was no statistically significant difference in the number of migraine episodes between the two groups. Conclusions: Compared to the placebo, ginger has a stronger efficacy in the prevention of migraine.

Background: Scutellaria platystegia Juz. is an herbaceous perennial, distributed in the northwest of Iran and southern Caucasian countries? Objectives: This study aimed to examine the antioxidant and antibacterial activities of the aerial part of S. platystegia and to determine the phytochemical constituents of its extract and essential oil. Methods: The ferric reducing ability of plasma (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods were used to examine the antioxidant effects of fractions obtained from the hydroalcoholic extract of the aerial part of S. platystegia. The antibacterial activity screening was also performed using the disk diffusion and microdilution methods. The phytochemical constituents of the most active fractions were investigated using column chromatography. Nuclear magnetic resonance (NMR) imaging and UV-Vis spectral analysis were used to determine the chemical structure of the isolated compounds. The GC-MS technique was also employed to identify the essential oil composition of the plant. Results: In the antioxidant activity assay, the n-butanol fraction was the most potent fraction, with a half maximal inhibitory concentration (IC50) of 16.14 ± 0.8 µg/mL on the DPPH assay and 736.4 ± 4.6 mmol FeSO4.7H2O equivalent per gram of sample on the FRAP assay. The n-butanol fraction exhibited very strong antibacterial activities against Staphylococcus aureus, Staphylococcus epidermidis, and Shigella dysenteriae (inhibition zone diameter: 20 - 25 mm, MIC: 125 - 250 µg/mL). The phytochemical analysis of the most active fractions resulted in the isolation of the following components from the chloroform fraction: 5,7,2'-trihydroxy-8,6'-dimethoxyflavone; 5-hydroxy-6,7,8,2',6'-pentamethoxyflavone; 5,2',6'-trihydroxy-7,8-dimethoxyflavone; 5,2',6'-trihydroxy-6,7,8-trimethoxyflavone; and 5,4'-dihydroxy-7-methoxyflavone. Besides, the following components were extracted from the n-butanol fraction: luteolin-7-O-β-D-glucopyranoside; verbascoside; apigenin; kaempferol; caffeic acid; rosmarinic acid; apigenin-7-O-β-D-glucopyranoside; apigenin-7-O-β-D-(-6''-(E)-caffeoyl)-glucopyranoside; and luteolin. Fourteen compounds were also identified in the plant essential oil; terpinen-4-ol (44.41%), α-terpineol (10.75%), caryophyllene oxide (9.61%), and thymol (8.73%) were the main compounds. Conclusions: This study introduced S. platystegia as a plant rich in bioactive phenolic compounds, with considerable antioxidant and antimicrobial activities. Therefore, it can be suggested as a potential candidate to be evaluated in future biological studies.

Background: Malaria is one of the most momentous transmittable diseases globally. Medicinal herbs like Artemisia species might be possible sources of new, effective, and cheap antiplasmodial products, making up the leading molecules to investigate new antimalarial drugs. The Artemisia genus, which belongs to the Asteraceae family, is a widely distributed medicinal plant in Iran. Methods: In this study, the antimalarial activities of essential oil, different extracts, and vacuum liquid chromatography (VLC) fractions of A. fragrans Willd. were examined by a cell-free β-hematin formation assay. The aerial parts of A. fragrans were extracted by a Soxhlet extractor, and essential oil was obtained by a Clevenger apparatus. Then, GC-MS analysis was used to identify volatile compounds of essential oil and the 100% VLC fraction of chloroform. Results: Among the extracts, chloroform extract illustrated considerable antimalarial activity compared to the control (P < 0.001), with the IC50 value of 1.22 ± 0.05 mg/mL. Among the fractions, 100% VLC fraction of chloroform extract illustrated potent antimalarial effects compared to the control (P < 0.001). The volatile oil demonstrated moderate antimalarial effects (P < 0.001) compared with the control. Besides, GC-MS determined that sesquiterpenes in the 100% ethyl acetate fraction of the chloroform extract and oxygenated monoterpenes in the essential oil might be responsible for the potent antimalarial activity of this plant. Conclusions: The 100% ethyl acetate fraction of chloroform extract along with the essential oil of A. fragrance indicated potent and moderate activity, possibly due to sesquiterpenes and oxygenated monoterpenes, respectively.

Context: Five species of the genus Ajuga (Lamiaceae) having the common name of "bugle" are found in Iran. In Persian medicine (PM), the genus Ajuga (Kamaphytus) is used for treating jaundice, joint pain, gout, amenorrhea, sciatica, and wound healing. This study aimed to review the ethnobotanical, phytochemical, and biological activities of Ajuga species that grow in Iran to determine their therapeutic potentials and suggest further studies on the healing properties of this genus in Iran. Evidence Acquisition: Electronic databases such as PubMed, Scopus, and Google Scholar were comprehensively searched for studies on Ajuga species in Iran, including "Ajuga austro-iranica," "Ajuga chamaecistus," "Ajuga comata" (Syn.: "Ajuga Chia," "Ajuga chamaepitys subsp. Chia"), "Ajuga orientalis," and "Ajuga reptans." The search period was from 1966 to February 2021. The related articles were selected according to the inclusion and exclusion criteria of the current study. Results: Several ethnobotanical and pharmacologic reports have verified the traditional uses of the genus Ajuga for anti-inflammatory, hypoglycemic, hypolipidemic, analgesic, anabolic, anti-arthritis, antipyretic, and hepatoprotective activities. Numerous phytochemicals have been identified from Ajuga species involving phytoecdysteroids, neo-clerodane-diterpenes, iridoids, flavonoids, withanolides, phenylethyl glycoside, and essential oils. Conclusions: Due to the beneficial therapeutic effects of Ajuga genus, it can be considered in future clinical studies as a source of natural antioxidants, dietary supplements in the pharmaceutical industry, and stabilizing food against oxidative deterioration.

Background: Scorpions and other venomous animals are sought with great concern because venom is a source of novel peptides with exciting features. Some toxins of scorpion venom are effectors of potassium channels. Previous studies strongly support the importance of potassium channel toxins for use as pharmacological tools or potential drugs. Objectives: Here, a three-dimensional (3-D) structure and function of a potent acidic blocker of the human voltage-gated potassium ion channel, Kv1.3, previously identified in the scorpion Mesobuthus eupeus venom gland, were interpreted. Methods: The 3-D structure of meuK2-2 was generated using homology modeling. The interaction of meuK2-2 with the Kv1.3 channel was evaluated using a computational protocol employing peptide-protein docking experiments, pose clustering, and 100 ns molecular dynamic simulations to make the 3-D models of the meuK2-2/Kv1.3 complex trustworthy. Results: A CSα/β (cysteine-stabilized α-helical and β-sheet) fold was found for the 3-D structure of meuK2-2. In a different mechanism from what was identified so far, meuK2-2 binds to both turret and pore loop of Kv1.3 through two key residues (Ala28 and Ser11) and H-bonds. The binding of meuK2-2 induces some conformational changes to Kv1.3. Eventually, the side chain of a positively charged amino acid (His9) occupies the channel's pore. All together blocks the ion permeation pathway. Conclusions: MeuK2-2 could block Kv1.3 by a new mechanism. So, it could be a unique target for further investigations to develop a pharmacological tool and potential drug.

Background: Stress-induced cellular senescence is a perpetual state of cell cycle arrest occurring in proliferating cells in response to stressful conditions. It is believed that oxidative stress plays a unique role in this process. As a reactive chemical compound that can induce oxidative stress, acrylamide is widely applied in several fields. Carvacrol is a liquid phenolic monoterpenoid found in essential oils of some plants and is known for its antioxidant and anticarcinogenic properties. Objectives: The current study aimed to evaluate the effects of carvacrol on oxidative stress and cellular senescence induced by acrylamide in the NIH 3T3 cell line. Methods: NIH 3T3 embryonic fibroblast cells were exposed to different concentrations of acrylamide, carvacrol, and H2O2 in a cell culture medium. The level of β-galactosidase (SA-β-gal) activity, as a marker of cellular senescence, was measured using staining and quantitative assays. Furthermore, to measure oxidative stress parameters, the content of glutathione and lipid peroxidation were determined. Results: Acrylamide could induce premature senescence evident by the elevated lipid peroxidation and SA-β-gal activity and declined cell viability and glutathione. Moreover, carvacrol showed beneficial effects on both acrylamide- and H2O2-induced cellular senescence by significantly reversing or subsiding the effect of oxidative stress and mediating its consequences. Conclusions: It can be concluded that carvacrol has protective effects against oxidative cellular senescence induced by acrylamide in the NIH 3T3 cell line.

Background: Acetaminophen (APAP) is a common analgesic and antipyretic medicine that can lead to acute liver injury at high doses. Crocin, a Crocus sativus’ ingredient, has potent antioxidant effects. Objectives: This study examined the protective effects of crocin against APAP-induced oxidative stress in mice. Methods: In this study, 56 mice were randomly divided into seven groups (n = 8 per group), including the negative (normal saline, 10 mL/kg) and positive (oral normal saline for five days + a single dose of APAP (300 mg/kg) on day 6th) control groups. The third group (NAC) received normal saline for up to five days, and on the 6th day, immediately after the administration of acetaminophen, received NAC (50 mg/kg). Groups fourth to sixth received respectively 12.5, 25, and 50 mg/kg of crocin (orally for six days), followed by a single dose of APAP (300 mg/kg) on 6th day. The last group received crocin (50 mg/kg) for six days. Then 24 h after the last injection, the animals were sacrificed, and samples were collected for biochemical and histopathological evaluations. Results: The levels of ALT, AST, and MDA increased, and the activity of CAT, GSH, and GPX decreased in the APAP-treated group compared to the control group. In APAP-treated groups, the administration of crocin decreased the serum levels of AST, ALT, and MDA and increased the activity of CAT, GSH, and GPX. Histopathological evaluations confirmed the above findings. Conclusions: According to our results, it seems that crocin has a protective effect against acetaminophen-induced liver toxicity and can be used as a therapeutic agent to treat APAP-induced hepatotoxicity.
