Hydroalcoholic Extract of Fumaria Parviflora L. Can Potentially Detoxificate HepG2 Cell Line Following Carbon Tetrachloride Exposure

Background: Fumaria Parviflora L. (FP) is a well-known herb in Iranian traditional medicine, widely used for gastrointestinal diseases. Additionally, the detrimental effects of carbon tetrachloride (CT) on the liver and kidneys have been scientifically established. Objectives: This study was designed to assess the therapeutic effects of FP on HepG2 cells exposed to CT toxicity. Methods: After treatment with hydroalcoholic extract of the FP plant and/or CT, cell viability (using the MTT technique and lactate dehydrogenase assay) and apoptosis (using the diphenylamine assay and Annexin V/PI staining) were investigated. The ratio of BCL2/BAX mRNA expression levels was measured using real-time PCR. Data were analyzed using SPSS software. Results: A significant (P < 0.05) reduction in cell viability was observed at doses of 100 and 200 µg/mL of FP in HepG2 cells. The decreased survival rate following CT exposure was concentration-dependent and significant (P < 0.05). The IC50 of CT was determined to be 1.05 μg/mL for 24 hours. Effective detoxification associated with CT was found at 6.25 µg/mL in both the pre-treatment and simultaneous treatment groups. Cell apoptosis was significantly (P < 0.05) decreased following FP administration in CT-treated cells, with an increase in the ratio of BCL2/BAX mRNA expression levels. Conclusions: The hydroalcoholic extract of FP demonstrated hepatoprotective effects on CT-treated HepG2 cells.

Antimalarial evaluation of selected medicinal plants traditionally used for treatment of fever, by inhibition test of heme polymerization

World Health Organization (WHO) has reported 249 million cases infected by malaria worldwide and 608 thousands deaths in 2022. Investigations for new antimalarial drugs from traditional medicine have proven to be more effective and less expensive. The medicinal plants that have been used for treatment of malaria, generally known as types of fevers in traditional medicine, can be suitable candidates for evaluating antimalarial effects. The aim of the present study was to evaluate the in-vitro mechanism of antimalarial action of selected medicinal plants by inhibition test of heme detoxification (ITHD). The methanol extract and fractions were prepared through maceration of the dry powdered plants. The ITHD method was carried in 96-wells plate and the percentage of heme polymerization inhibition was determined. The cytotoxicity of the effective plants were examined on MDBK cell line by MTT assay. Bioassay guided fractionation was performed exposing to size exclusion column chromatography and liquid-liquid fractionation and was assayed by the ITHD method for the sample with the least IC50 value and lowest cytotoxic effect. The methanol fraction of Viola odorata whole plant showed the most considerable results among the tested plants with IC50 171.8 μg.mL-1 beside the lowest cytotoxic effects. This fraction by the bioassay guided fractionation led to fraction SB2 and this fraction demonstrated the most effective result with lowest IC50 = 14.8 ± 3µg.mL-1 in ITHD assay. Regarding the results of the present study and the traditional use of V. odorata for overcoming fever in Iranian traditional medicine, the final fraction of the plant could be proper candidate for further phytochemical and antimalarial studies.

Cytotoxic Activity and Phytochemical Analysis of Artemisia biennis Essential Oils at Different Growth Stages

Background: The Artemisia genus is well-known for its medicinal properties, particularly in Iranian traditional medicine. Artemisia biennis, a species within this genus, is widely distributed across Iranian rangelands. Objectives: This study aimed to evaluate the cytotoxic activity and chemical composition of essential oils (EO) isolated from the aerial parts of A. biennis in Iran at different growth stages. Methods: The aerial parts of A. biennis from northeast Iran were collected during June (early vegetative stage), July (pre-flowering stage), August (full-flowering stage), and October (late vegetative stage). The essential oils (EOs) of the A. biennis species were extracted by hydro-distillation using a Clevenger-type apparatus and analyzed using gas chromatography–mass spectrometry (GC/MS). The cytotoxic activity of the EOs against normal fibroblasts, MCF-7, and HT-29 cell lines was evaluated using the MTT assay. Results: Data from GC/MS analysis revealed that (Z)-nerolidol (22.62 - 54.4%), (E)-β-farnesene (6.89-16.38%), and (Z)-tonghaosu (12.33 - 18.61%) were the most abundant chemical constituents. The essential oil (EO) of A. biennis was characterized by a high content of oxygenated sesquiterpenes, with (Z)-nerolidol being the main constituent identified. Based on the MTT assay, the EO of the plant species collected in June exhibited the most potent cytotoxicity against MCF-7 (IC50 = 2.84 ± 0.15 µg/mL) and HT-29 cell lines (IC50 = 2.41 ± 0.2 µg/mL). Conclusions: The growth stage of A. biennis affects EO yields, the composition of extracted secondary metabolites, and cytotoxic activity. A. biennis EOs can be considered potential sources of cytotoxic phytochemicals.

Volatile compositions and glandular trichomes of Zataria multiflora in different phenological stages under normal and drought stress conditions

BackgroundZataria multiflora Boiss. is a medicinal and aromatic plant from the Lamiaceae family. It is extensively used in Iranian traditional medicine, mostly as a replacement for Thyme species. This study was focused on the analysis of chemical composition and the distribution and types of trichomes of Z. multiflora grown under different conditions. Equilibrium headspace analysis in combination with GC-FID-MS was used to identify volatile compounds released by aerial parts of Z. multiflora in development stages of 50 and 100% flowering under normal and drought-stress conditions.ResultsThe main constituents were p-cymene (20.06–27.40%), γ-terpinene (12.44–16.93%), and α-pinene (6.91–16.58%) and thymol (8.52–9.99%). The highest content of p-cymene (27.40%) and thymol (9.99%) was observed in the 50% flowering stage at the 90% field capacity, while the maximum γ-terpinene (16.93%) content was recorded in the 100% flowering stage under normal conditions. Using the SEM method, it was found that peltate glandular and non-glandular trichomes are distributed on the surface of the leaf, stem, and outer side of the calyx. However, capitate trichomes only are detected on the stem and calyx in the 100% flowering and beginning of blooming stages, respectively. The type and structure of trichomes do not vary in different development stages, but they differ in density. The highest number of leaf peltate glandular trichomes was observed in the vegetative and beginning of blooming stages at 50% and 90% field capacity, respectively. Non-glandular trichomes of the stem were observed with high density in both normal and stress conditions, which are more densely in 90% field capacity.ConclusionsSince this plant has strong potential to be used in the food and pharmacological industries, this study provides valuable information for its cultivation and harvesting at specific phenological stages, depending on desired compounds and their concentrations.

Phoenix dactylifera L. pollen versus pentoxifylline on improvement of sperm parameters in idiopathic male infertility: A randomized clinical trial

Ethnopharmacological relevancePhoenix dactylifera L. pollen is the male reproductive dust of palm flowers known as a natural product that is considered a strong stimulant of sexual potency and fertility in Iranian traditional medicine (ITM). In this regard, no evidence-based medications are empirically prescribed to treat IMI. However, applying traditional medicine for the treatment of male infertility has attracted more attention in recent years. Aim of the studyPhoenix dactylifera L. pollen was compared with pentoxifylline (PTX) to evaluate its efficacy on sperm parameters. Materials and methodsDuring this parallel randomized controlled trial, 80 adult men with asthenozoospermia, oligozoospermia, or teratozoospermia (age 20–35 years) were enrolled. In two separate groups of participants with a 1:1 ratio, participants received either 6 g of Phoenix dactylifera L. pollen powder daily or 400 mg of PTX tablets daily for 90 days. We measured the sperm parameters as well as the serum sex hormones in the sample. ANCOVA and t-tests were used to compare groups. ResultsThere was no significant difference between the study groups in terms of baseline characteristics or demographic characteristics. According to the results, participants who took Phoenix dactylifera L. pollen powder had significantly improved sperm concentration (p = 0.016), morphology (p = 0.029), sperm counts (p = 0.012), progressive motility (p = 0.016), total motility (p = 0.018), and reduced immotile sperms (p = 0.014) compared to those who took PTX. ConclusionsIn light of these results, Phoenix dactylifera L. pollen is recommended as a treatment factor for ameliorating IMI by enhancing sperm functional capacity and semen parameters.

Deciphering the antidepressant effects of Rosa damascena essential oil mediated through the serotonergic synapse signaling pathway

Ethnopharmacological relevanceRosa damascena is an ancient plant with significance in both medicine and perfumery that have a variety of therapeutic properties, including antidepressant, anti-anxiety, and anti-stress effects. Rose damascena essential oil (REO) has been used to treat depression, anxiety and other neurological related disorders in Iranian traditional medicine. However, its precise mechanism of action remains elusive. Aim of the studyThe aim of this study was to investigate the impact and mechanism underlying the influence of REO on chronic unpredictable mild stress (CUMS) rats. Materials and methodsGas chromatography-mass spectrometry (GC-MS) technique coupling was used to analyze of the components of REO. A CUMS rat model was replicated to assess the antidepressant effects of varying doses of REO. This assessment encompassed behavioral evaluations, biochemical index measurements, and hematoxylin-eosin staining. For a comprehensive analysis of hippocampal tissues, we employed transcriptomics and incorporated weighting coefficients by means of network pharmacology. These measures allowed us to explore differentially expressed genes and biofunctional pathways affected by REO in the context of depression treatment. Furthermore, GC-MS metabolomics was employed to assess metabolic profiles, while a joint analysis in Metscape facilitated the construction of a network elucidating the links between differentially expressed genes and metabolites, thereby elucidating potential relationships and clarifying key pathways regulated by REO. Finally, the expression of relevant proteins in the key pathways was determined through immunohistochemistry and Western blot analysis. Molecular docking was utilized to investigate the interactions between active components and key targets, thereby validating the experimental results. ResultsREO alleviated depressive-like behavior, significantly elevated levels of the neurotransmitter 5-hydroxytryptamine (5-HT), and reduced hippocampal neuronal damage in CUMS rats. This therapeutic effect may be associated with the modulation of the serotonergic synapse signaling pathway. Furthermore, REO rectified metabolic disturbances, primarily through the regulation of amino acid metabolic pathways. Joint analysis revealed five differentially expressed genes (EEF1A1, LOC729197, ATP8A2, NDST4, and GAD2), suggesting their potential in alleviating depressive symptoms by modulating the serotonergic synapse signaling pathway and tryptophan metabolism. REO also modulated the 5-HT2A-mediated extracellular regulated protein kinases-cAMP-response element binding protein-brain-derived neurotrophic factor (ERK-CREB-BDNF) pathway. In addition, molecular docking results indicated that citronellol, geraniol and (E,E)-farnesol in REO may serve as key active ingredients responsible for its antidepressant effects. ConclusionsThis study is the first to report that REO can effectively alleviate CUMS-induced depression-like effects in rats. Additionally, the study offers a comprehensive understanding of its intricate antidepressant mechanism from a multi-omics and multi-level perspective. Our findings hold promise for the clinical application and further development of this essential oil.

Effects of the Allium jesdianum extract on calcium oxalate crystallization with purification and identification of its major compounds

Allium jesdianum, a plant utilized in traditional Iranian medicine, has been historically recognized for its efficacy in countering urolithiasis and alleviating kidney pain. In this study, we investigated the hydroalcoholic extract of A. jesdianum for its potential inhibitory effects on calcium oxalate crystallization (in vitro).The study employed spectrophotometric analysis and microscopic observation to quantify sodium oxalate-induced crystallization, nucleation, and aggregation. The extract of A. jesdianum at concentration of 32 mg/mL exhibited significant potential in inhibiting crystal growth, aggregation, and reducing crystal particle size. Phytochemical analysis of the extract disclosed the presence of three known phenolic and two identified steroid compounds, offering initial insights into its bioactive constituents. A. jesdianum emerges as a promising candidate for the development of plant-based oxalate anticrystallization drugs. The therapeutic mechanisms might be attributed to pain control and the presence of phenolic compounds acting as free radical scavengers, disrupting stone formation signaling pathways. However, further investigation is required to elucidate specific chemical structures related to these activities.

Investigating the Relationship between Somatotype and Temperament (Mizaj) in Non-athletic Male Students

Introduction: Somatotype is one of the effective factors in predicting the success of athletes in various sports. Somatotype can be a determining factor in individual differences. In traditional Iranian medicine, the relationship between people’s temperaments (Mizaj) on the one hand and their physical structure and physiological and psychological performance on the other has been discussed. Therefore, this study aimed to investigate the relationship between somatotype and Mizaj in male non-athlete university students in Mashhad. Materials and Methods: This analytical cross-sectional study was conducted on male students at Ferdowsi University of Mashhad in the winter of 2016. The sample consisted of 200 individuals who were divided into four groups of 50 people based on their Mizaj: warm and wet, warm and dry, cold and wet, and cold and dry. The relationship between the Mizaj index and somatotype was investigated using the Eta correlation coefficient method. Data analysis and hypothesis testing were tested in SPSS software version 21 with a significance level of p ≥ 0.05. Results: Statistical results showed that the Eta correlation coefficient between the endomorphic type and Mizaj was 0.89. The results of one-way analysis of variance showed that cold and wet Mizaj had a significantly higher endomorphic score than other types of Mizaj (4.91±0.58) (P=0.001). Moreover, the correlation coefficient of Eta between mesomorphic type and Mizaj was 0.924. It was also found that the warm and wet Mizaj had the significantly highest mesomorphic score (5.12±0.49). The correlation coefficient of Eta between ectomorphic type and Mizaj was 0.946 (P=0.001), and cold and dry Mizaj had the significantly highest ectomorphic score compared to other types of Mizaj (4.83±0.45). Conclusion: The results of this study showed that there was a significant relationship between Mizaj and the body type of young men. Therefore, since the structure of a person’s body type can be a predictor of success in any of the various sports, Mizaj can be used to determine a person’s athletic talent.

Iranian Traditional Medicine for Treatment of Attention Deficit Disorder with Hyperactivity in Children: A Systematic Review of Randomized Controlled Trials.

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder with a complex etiology. Stimulants as a first-line treatment are not effective in some cases. In this study, we conducted a systematic review to evaluate the efficacy of traditional Persian Iranian medicine (TIM) for children and adolescents with ADHD. Data were collected mainly from PubMed, Google Scholar, Web of Science, ProQuest, and Scopus databases until Dec 2022. The keywords related to ADHD, traditional Persian medicine (TPM), and (TIM) were searched. Two reviewers independently screened 714 abstracts and eventually, eight trials were included in the systematic reviews. Changes in the severity of ADHD symptoms were considered based on the validated cutoff on recognized rating scales as the result of the effect of TIM on ADHD. Interventions included herbal extracts of Passiflora incarnate, whey protein, Ginkgo biloba, Crocus sativus L, sweet almond syrup, and horse milk. In all studies, except G. biloba, there was evidence of a reduction in the severity of ADHD. Low evidence could be found for G. biloba. Herbal and traditional remedies are an efficient and safe solution to alleviate the symptoms of ADHD. In future studies, TIM as a complementary therapy may be useful to alleviate ADHD symptoms, especially in children who are resistant to stimulant medications.

Investigating the effect of hydroalcoholic extract of Prosopis farcta fruit on the toxicity induced by temozolomide in glioblastoma cell line in vitro

Introduction: Glioblastoma multiforme (GBM) is one of the most common human brain tumors. The use of temozolomide drug can be mentioned among the treatment methods. Researchers are trying to use methods to overcome resistance to temozolomide. Regarding the anticancer effects of Prosopis farcta in traditional Iranian medicine, the present study aimed to investigate the effect of the fruit hydroalcoholic extract of Prosopis farcta on the toxicity induced by temozolomide in the GBM cell line. Method: The T98G cell line was treated with plant extract and temozolomide. The cell survival rate was evaluated by MTT assay. The type of interaction between herbal extract and temozolomide was evaluated using the MTT test and Compusyn software. In addition, the amount of nitric oxide production in cancer cells was measured. Furthermore, the expression of the O-6-Methylguanine-DNA Methyltransferase (MGMT) gene was evaluated by Real-time PCR. Results: Hydroalcoholic extract of the plant and temozolomide decreased cell viability in a concentration- and time-dependent manner. The combination of extract and temozolomide had a synergistic effect in reducing cell survival. The hydroalcoholic extract and/or temozolomide caused a significant decrease in nitric oxide production and secretion (P&lt;0.05). Considering the expression of MGMT, the hydroalcoholic extract and temozolomide significantly decreased and increased the expression of this gene, respectively (P&lt;0.05). Simultaneous treatment caused a significant decrease in MGMT expression compared to the group treated with temozolomide (P&lt;0.05). Conclusion: The combination of Prosopis farcta fruit extract and temozolomide had synergistic antitumor potential in GBM cells. This extract could reduce cellular resistance to temozolomide through the downregulation of MGMT expression.

Antifatigue Effects of the Aqueous Extracts of Myrtle Berries, Apple and Clove: An Animal Study.

Fatigue is one of the most prevalent symptoms, increasing worldwide with no specific medication for fatigue. Iranian traditional medicine (ITM), or Persian medicine, is a reliable source for discovering natural medicine for diseases and their symptoms. Myrtus communis L. (Myrtle), Malus domestica Borkh. (Apple), and Syzygium aromaticum (L.) Merr. & L. M. Perry (Clove) have been utilized as brain and heart tonics in ITM. Based on ITM, cardiac tonics decrease fatigue by enhancing heart function and increasing blood flow to tissues. These plants, particularly myrtle berries, have been utilized as potent enlivening agents that reduce mental fatigue. This study aims to investigate the effects of aqueous extracts of these plants on weight-loaded forced swimming (WLFS) tests and three doses of aqueous myrtle extract in an animal model of chronic sleep deprivation-induced fatigue. Five groups of rats (n = 6) were evaluated: Sham, control, apple-treated, clove-treated, and myrtle-treated groups. After 28 days of treatment, the WLFS test was performed, and swimming time was recorded. Subsequently, central fatigue was induced in rats by chronic sleep deprivation for 21 days. Five groups of rats (n = 6) were evaluated: Sham, control (sleep-deprived, which received water), and three sleep-deprived + treatment groups, which received aqueous myrtle extract (350, 700, and 1000 mg/kg). An open field test on the 20th day and a WLFS test on the 21st day were performed. The myrtle berries significantly increased glucose, reduced lactate dehydrogenase (LDH) levels, and enhanced swimming time. Fatigue caused by chronic sleep deprivation increased malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and LDH while decreased superoxide dismutase (SOD), glucose, and swimming time. In all treatment groups, SOD levels and swimming time were increased, whereas MDA, IL-1β, and TNF-α levels were decreased significantly. Only the 1000 mg/kg dose significantly reduced LDH levels (P < 0.001). The treatment significantly improved the velocity and the total distance moved in the open-field test. According to the results, the myrtle berries reduced fatigue in two animal models, probably due to its phenolic compounds, flavonoids, and polysaccharides.
