Severe disease onset of COVID-19 may result in alveolar injury and respiratory failure. Apoptosis and inflammation are the main causes of respiratory distress syndrome. Berberine is used in medicine as an analgesic, anti-asthmatic, anti-inflammatory, and antiviral. In the current investigation, the effect of berberine on COVID-19 outpatients was studied. The present clinical trial was performed on 40 outpatients who were randomly assigned to berberine (300 mg, TID, 2 weeks) (n=19) or placebo groups (n=21). Both groups received standard therapy and they were monitored on days 3, 7, and 14 after the beginning of the therapy for clinical symptoms’ improvement, quantitative CRP, lymphopenia, CBC, and SpO2. The severity and frequency of these symptoms and the level of the parameters were statistically compared between the two groups. On days (0, 3, 7, and 14, there was no significant difference between the berberine and placebo groups in the improvement of clinical symptoms (cough, shortness of breath, nausea, loss of smell and taste, diarrhea, dizziness, sore throat, stomachache, body aches, and body temperature), quantitative CRP, lymphopenia, WBC, neutrophils, platelets, or SpO2. Berberine (300 mg, TID, two weeks) is ineffective in treating COVID-19. More research with a larger sample size is needed to investigate different berberine dosages in other pharmaceutical formulations.

Cancer development is a multi-stage process in which apoptosis plays an important role. Apoptotic agents from natural products like phenolic compounds can be used effectively in the treatment of cancer. Berberis vulgaris L. fruits are a rich source of natural phenolic compounds and have been evaluated for their apoptotic effects.

this study was carried out to evaluate the apoptotic effect of B. vulgaris fruits in normal and cancerous cells by investigating p53, Bax, and Bcl-2 genes expression and identifying an active compound.

B. vulgaris fruits were extracted with ethanol using maceration method. To yield an active compound, the extract was divided into fractions and subfractions that could be evaluated using chromatography techniques, and the purified compound structure was determined by nuclear magnetic resonance (NMR). The cytotoxic activity of the selected fraction against 3T3 and MCF-7 cell lines along with its effect on the mRNA apoptosis regulating genes like p53, Bax, and Bcl-2 were investigated subsequently.

Results showed that B. vulgaris extract increased the mRNA level of p53 and Bax and decreased Bcl-2 mRNA level in cancer cell lines. The structure of the purified compound was determined as the 3-caffeoylquinic acid (chlorogenic acid).

B. vulgaris fruit has in vitro antineoplastic activity by stimulating cellular apoptosis via increasing the levels of p53 and Bax proteins and decreasing Bcl-2 and comprises chlorogenic acid as one of its phenolic phytochemicals.

Modern treatment of peptic ulcers includes antibacterial and gastroprotective medications. However, current anti-ulcer drugs possess severe side effects. Therefore, all attempts to find new effective medications free from side effects are justified. Though Berberis vulgaris is a medicinal plant commonly used for the treatment of numerous disorders, gastroprotective effect of its leaf extract was not investigated before. Gastric ulcer was modelled in Sprague-Dawley rats after treatment with B. vulgaris leaf extract containing 0.07% of alkaloids, 0.48% of flavonoids and 8.05% of tanning substances, 10 or 50 mg of dry extract/kg, changes in the stomach mucosa were assessed semi-quantitatively, and the gastric wall was evaluated for prostaglandin E2 level using ELISA and assessed histologically by calculation of the lesion index. B. vulgaris leaf extract at the dose of 50 mg/kg reduced the macroscopic ulcer score and the microscopic lesion index, increased prostaglandin E2 concentration in the gastric wall significantly higher than atropine and B. vulgaris leaf extract 10 mg/kg. The gastroprotective effect of the high dose of B. vulgaris leaf extract may be due to stimulation of prostaglandin E2 secretion in the stomach, and anti-oxidative and anti-inflammatory properties of polyphenolic complex of flavonoids and tannins present in the leaves of this plant.

Ionotropic glutamate NMDA receptors are multi-subunit proteins with few selective pharmacological ligands and are tentatively implicated in MS and other neurodegenerative disorders. The present study was aimed at evaluating the antioxidant properties of Berberis vulgaris extract-loaded magnetite nanoparticles on the Grin1 gene expression in NMDA receptor in EAE Syrian mice.
EAE mice models were generated through active immunization with MBP and PTx and kept for days 9-14 until EAE signs appeared followed by administration of barberry extract loaded magnetic nanoparticles.
Pure BE concentrations did not show recovery signs until days 7-9, but partial recovery in tail movement was seen on days 11 and 14, which was significant as compared to the control group in terms of improvement of the clinical scores. Meanwhile bare nanoparticles had neither disease recovery/progression properties nor EAE mice mortality as compared to controls, but 1 mg BE + Fe3O4 reduced EAE symptom severity and resulted in significant improvement of hind limb sensitivity to toe pinching and improved tail movements. Meanwhile 2 mg Be + Fe3O4 showed much better sensitivity to toe pinching and complete tail recovery. qRT-PCR analysis showed a significant decrease in relative Grin1 expression in female mice after treatment with 0.2 and 1 mg BE. However, a profound decrease in Grin1 expression was seen at 0.2, 1 and 2 mg BE + Fe3O4 treated groups in a dose-dependent manner.
The results indicated that Fe3O4+ BE could alleviate the EAE severity and progression

In this research, nitrite was partially replaced with different concentrations of Berberis vulgaris and Rosmarinus officinalis (0, 30, 60, 90 mg/kg) extracts in the unfermented sausage. Samples were kept at refrigerator temperature and physicochemical and organoleptic evaluations of treatments were performed. The findings showed an increase in moisture and ash content and a decrease in fat and protein content, and IC50 by increasing the storage time. The highest level of antioxidant activity was reported for treatment with 90 mg/kg R. officinalis extract. As for sensory properties, 60 mg/kg treatment showed the highest sensory score after the control sample; however, 30 mg/kg treatment had the highest score in terms of consistency after the control sample. It can be concluded that 60 mg/kg R. officinalis extract has a better potential to improve the qualitative characteristics of unfermented sausage and it can be a proper substitute for decreasing the nitrite in sausage formulations.

 Recently, due to the numerous applications of silver nanoparticles (AgNPs) in industry, various routes to synthesize them have been developed.

 The current study was aimed at synthesizing silver nanoparticles by the leaf extract of Berberis vulgaris and evaluating the cytotoxic effects on human breast cancer MCF-7 cell line.

 The leaf extract of Berberis vulgaris and silver nitrate solution were used to synthesize silver nanoparticles. Ultraviolet (UV)-visible, Fourier-transform infrared, and X-ray diffraction analysis spectroscopy and transmission electron microscopy methods were used to characterize and confirm the nanoparticles’ synthesis. The cytotoxic activity of synthesized nanoparticles (0, 5,10, 20, 40 µg/mL) was also studied by MTT assay.

 The results showed that Ag nanoparticles were polydisperse and spherical in shape and had a size of about 19.9 nm. Silver nanoparticles reduced the growth of cancerous cells based on time and concentration. The IC50 for MCF-7 cells at 48 hours was 20.27 µg/mL.

 The findings showed that synthesized nanoparticles have an appropriate cytotoxic effect on cancer cells. This impact may be due to the production of free radicals through the release of Ag ions.

Although the efficacy of selected training and antioxidant herbs in the treatment of diabetes mellitus has been determined, the interactive effect of selected training and aqueous extract of barberry on insulin resistance and risk factors of type2 diabetes mellitus is not well understood. The aim of the present study was to investigate the effect of aqueous extract of barberry and selected training on some blood factors in men with type2 diabetes.

In this study, 48 middle-aged men an age range of 40-50 years with type2 diabetes participated in the study. The participants were randomly divided into four groups of 12 subjects, including(1)control, (2)aqueous extract of barberry consumption, (3)aerobic training, and (4)aerobic training+ barberry consumption, based on insulin resistance index. The participants in the aqueous extract of barberry consumption group received200 ml of barberry juice daily for8 weeks and the training and training+ barberry consumption groups performed the training protocol designed in the study for 8 weeks, while the control group did not receive any intervention.

After 8 weeks of exercise training and consumption of aqueous extract of barberry, insulin resistance index, fasting insulin level, fasting blood glucose level, triglyceride level, low density lipoprotein (LDL)and total cholesterol were significantly decreased compared to the control group and high density lipoprotein (HDL)had a significant increase; on the other hand, regarding the intergroup changes, only the levels of LDL and CHO were significant compared to the aqueous extract of barberry consumption and aerobic training.

In general, aqueous extract of barberry consumption and regular exercise training seems to be effective in improving insulin resistance index and blood lipids levels in type2 diabetic patients.

There are several studies reporting the therapeutic effects of Berberis vulgaris on liver diseases. This study was done with the purpose of examining the effect of B. vulgaris oxymel (BO) in patients with refractory primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC), who did not respond to current treatment.

Patients with PSC or PBC who were receiving ursodeoxycholic acid (UDCA, 13-15 mg/kg/day) for at least six months, but their serum levels of alkaline phosphatase (ALP) were still 1.5 folds higher than the normal upper limit during the last six months, were asked to participate in this quasi-experimental study. Patients were asked to take 0.5 ml/kg/day of BOtwo times a day for three months along with UDCA. At the end of the study, serum levels of ALP, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), total bilirubin (TB), direct bilirubin (DB), and creatinine as well as prothrombin time (PT), international normalized ratio (INR) and quality of life  (QOL) based on PBC-40 questionnaire were assessed as outcomes.

Our results showed that BO notably attenuated the serum levels of ALP, AST, ALT, GGT, TB, and DB, as well as PT and INR and significantly improved QOL.  

For first time, we showed that additional therapy with BOhas a promising effect in the treatment of refractory PSC and PBC.

Although there are improvements in breast cancer diagnosis and treatment methods, some breast tumor cells still are resistant to current therapies. Thus, there are attempts all over the world to find an effective way with more toxicity to tumor cells and less to normal cells. In recent years, mesenchymal stem cells (MSCs), due to their native tumor homing property, have been introduced as expression vectors for anticancer proteins, such as TNF-related apoptosis-inducing ligand (TRAIL). However, most tumor cells are resistant to TRAIL or show low sensitivity to it. Thus, it is necessary to find a way to increase the sensitivity of cancer cells and decrease their resistance. One of these ways is combination therapy with herbal drugs.

This study aimed to investigate the combination of sub-toxic doses of aqueous extract of Berberis vulgaris (AEBV) and MSC-TRAIL on MCF-7 cells as a human breast cancer cell line.

Experiments were set based on in vitro cell culture. Combination therapy was carried out in transwell co-culture plates. The cell viability was determined by the MTT assay. The cell cycle was measured using the Propidium Iodide (PI) staining flow cytometry method. All experiments were performed in triplicate. The data were analyzed by One-way ANOVA test using SPSS software.

MCF-7 cells were relatively resistant to MSC-TRAIL and AEBV alone, while a sub-toxic concentration of AEBV (0.5 mg/mL) combined with MSC-TRAIL significantly increased death in MCF-7 cells, showing a synergistic effect.

Berberis vulgaris contains antioxidants that can inhibit DNA cleavage. The purpose of this study was to evaluate the antioxidant and protective activity of B. vulgaris on DNA cleavage. In this study, the antioxidant capacity of B. vulgaris was investigated using DPPH and its protective effect was evaluated on pBR322 plasmid and lymphocyte genomic DNA cleavage induced by Fenton reaction, by DNA electrophoresis. Aqueous extract of B. vulgaris presented dual behavior with a potent antioxidant activity at 0.25and 0.75mg/ml for pBR322 plasmid and lymphocyte genomic DNA, respectively, but a pro-oxidant activity was observed at higher concentrations. Our results indicated that B. vulgaris extract an inhibit Fenton reaction-induced DNA cleavage and oxidative cleavage of double-stranded DNA assay is a powerful technique that can be used to determine the antioxidant and pro-oxidant properties of a compound on cellular components such as DNA.

Hepatic sickness is a serious problem for human health. The researchers are interested in using medicinal plants including barberry to cure many of these sicknesses. In this study, the effect of hydroalcoholic extract of Berberis vulgaris leaf on hepatic protection was assessed in rats.

Forty healthy male Wistar rats were divided randomly into five groups (n = 8): Group 1 (healthy control), intraperitoneal injection of olive oil; Group 2 (hepatotoxic control), intraperitoneal injection of carbon tetrachloride and daily gavage of distilled water; and testing groups, intraperitoneal injection of carbon tetrachloride along with daily gavage of B. vulgaris leaf extract 40, 80, and 120 mg/kg of weight, respectively. After 6 weeks, the following were checked: enzyme level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), as well as serum level of total protein (TP), albumin (ALB), and histopathological status of the liver.

The level of AST, ALP, and ALT was increased to 109 (IU/L), 95(IU/L), and 71(IU/L), respectively, in hepatotoxic control group than healthy control group, and there was a decrease of 0.86 (g/dl) and 0.04 (g/dl) in TP and ALB levels, respectively. The B. vulgaris extract in every three doses caused a significant decrease in hepatic enzymes level. However, the TP had a significant increase in 80 and 120 mg/kg of body weight. Regarding ALB, there was no significant difference among these groups. The histopathological results were not conformed to biochemical findings.

Using the appropriate dose of B. vulgaris leaf extract can help the improvement of laboratory symptoms of fatty liver.

Surgery is one of the most common strategies to treat hydatidosis reserved as a complementary treatment with chemical agents. Due to low efficacy and the adverse effects of these chemical agents, it is necessary to develop a new and effective scolicidal agent to prevent the recurrence of hydatidosis after surgery. The current study aimed at investigating the scolicidal effects of Berberis vulgaris, Peganom harmala, and Zataria multiflora methanolic extracts on protoscolices of hydatid cyst. Protoscolices were aseptically obtained from sheep livers infected with hydatid cyst in Hamadan slaughterhouse (Hamadan, Iran). After methanol extraction of herbs, different concentrations of extracts were used in various exposure time for mortality rate assay of protoscolices in laboratory. The obtained results showed that various concentrations of B. vulgaris and Z. multiflora extracts could kill 100% of protoscolices after five minutes of exposure and the mean of mortality rate of protoscolices was remarkably higher in the experiment group comparison with that of the control group (P < 0.05). However, the current study findings showed that P. harmala extract at a higher concentration (100 mg/mL) killed 14%, 12%, 12.67%, 15.67%, and 17% of the protoscolices after 5, 10, 15, 20 and 40 minutes of exposure, respectively. There was no significant difference between the experiment and control groups in terms of the mean of mortality rate (P > 0.05). The current study findings showed that B. vulgaris and Z. multiflora extracts can be natural sources to develop new scolicidal agents used in hydatid cyst surgery to prevent recurrence of the disease. However, the in vitro examination revealed that the P. harmala extract had no strong scolicidal activities.

Dendritic cells (DCs) have been recently employed as carriers for vaccines against several viral infections. The present study was designed to develop a prophylactic vaccine against hepatitis C virus (HCV) using DCs treated with Berberis vulgaris root extract (BRE), as a preclinical study.
BRE was prepared and injected to female BALB/c mice for DCs expansion. The expanded splenocyte cells (EDC) were purified and efficiently loaded ex vivo with HCV-nonstructural protein 3, NS3, (EDC-NS3). Mice were subcutaneously inoculated with EDC-NS3 vaccine candidate thrice with 4-week-intervals and IL-12, IFN-γ, IL-4, IL-10, MHC class II, CD3, CD16, indoleamine 2, 3 dioxygenase (IDO) and total protein levels were measured, post-vaccination by PCR and flow cytometry. Moreover, cytotoxic T lymphocyte and humoral immune responses were examined.
Our data revealed that immunization with EDC-NS3 vaccine elevated IL-12, IFN-γ and IL-4 expressions as well as MHC II and CD16 at protein levels. It also elicited strong HCV-NS3-specific humoral and cellular immune responses. However, the expressions of CD3, IDO, and IL-10 were down-regulated, post-vaccination.
EDC-NS3 immunization serves as an innovative modality for immunoprophylaxis against HCV infection.

Researchers have recently focused on the use of natural compounds, especially essential oils of high antioxidant and antimicrobial properties in order to reduce the risks of synthetic preservatives.
Also Therefore, the present study examined the antimicrobial and antioxidant properties of Zataria multiflora Boiss essential oil and Berberis vulgaris water and ethanol extract (BGE).
In this experimental study, the components of the essential oil were analyzed by GC/MS. The minimum inhibitory concentration (MIC) was determined by the last well without turbidity, the minimum bactericidal concentration (MBC) was determined by culturing the wells without turbidity, and the least concentration of essential oil that inhibits bacterial growth was determined by microdilution method. The antioxidant activity of different concentrations of ZEO and BGE was measured by 2, 2-diphenyl, 1-picrylhydrazyl (DPPH) radical scavenging, β-carotene-linoleic acid assays and the level of total phenolic.
Thymol was found to be the major component of ZEO through chemical composition analysis (44.82%). The results of antioxidative tests indicated that BGE was significantly more potent (P The results of this study showed that water and ethanol extracts of BG and essential oil of ZEO have antibacterial and antioxidant properties. Hence, it is suggested that these compounds be added to food products to increase their shelf life

Toxicopathological effects of herbs have always been a major concern. There is scant information available about the toxicopathological effects of barberry in the fetus. Since the embryogenesis in chicken is similar to human beings, the objective of this study is to evaluate the lesions of the various dosages of Berberis vulgaris using a chicken embryonic model. Fertile chicken eggs were divided into four equal treatment groups; phosphate buffered saline-injected group and barberry-injected groups whose individuals were injected with Berberis vulgaris fruit-extract at dosages of 10, 50 and 100 mg per Kg egg-weight, respectively. Embryos were re-incubated post-treatment and allowed to develop until day 18, after which they were examined for macroscopic and microscopic lesions. Results showed that embryos were stunted in the barberry-injected groups. Defect in feather growth and general congestion was accompanied by pathological changes in brain, liver, kidney, heart and lung. Histopathological lesions include congestion, hemorrhage, edema and micro-thrombosis in the affected organs. Based on findings, it is concluded that Berberis vulgaris at the above-mentioned concentrations is toxic to the chicken embryo in a dose dependent manner. Further studies are needed to clarify the toxic effects of this herb on the development of human fetus.

The methanolic extracts of Nigella sativaL. seeds (MENS) and Berberis vulgaris L.(MEBV) were investigated for treatment of Haemoproteus columbae-infected pigeons (Columba livia domestica).
One hundred twenty naturally-infected pigeons were randomly divided into four groups of thirty each. Two groups were treated separately with the extracts, while the positive and negative control groups were given buparvaquone (Butalex®) and distilled water, respectively. The parasitaemia rate was calculated in all groups before and after the experiment at four-day intervals for16 days.
The results showed a high therapeutic effect for MENS with a progressive decrease in average parasitaemia rate from 18.17% before treatment to 0.73% at the end of treatment (p0.05).
Methanolic extracts of N. sativa showed therapeutic effects against H. columbae and may be regarded as a suitable choice for further studies to develop new drugs against blood parasites, in both animals and human beings.

BACKGROUND/ The aim of this study was to investigate the effect of Berberis vulgaris (BV) juice consumption on insulin homeostasis, glycemic profiles of patients with benign breast disease (BBD).
SUBJECTS/ This parallel design, triple-blind, randomized and placebo controlled clinical trial was conducted on 85 eligible women diagnosed with BBD who recruited from Nour-Nejat hospital, Tabriz, Iran. Participants were randomly allocated into either intervention group who received BV juice (480 ml/day, n=44) or BV juice placebo group at the same time (480 ml/day, n=41). After a 7 day run-in period, treatments were administered for the duration of 8 weeks. Participants, care givers and those who assessed laboratory analyses were blinded to the assignments (IRCT registry no: IRCT2012110511335N2).
The relative treatment effects of BV supplementation showed decreased serum levels of insulin for 19%, C-peptide for 8%, homeostasis model assessment of insulin resistance index (HOMA-IR) for 16% and glucose to insulin ratio for 22% but HOMA-B increased 44% relative to placebo group over 8 weeks BV supplementation. Although these changes were not statistical significant, the mean changes for C-peptide and HOMA-B were significant just after adjusting for baseline data and covariates.
Administration of BV juice showed controlling effects on HOMA related indices, consequently might have beneficial effects on insulin signaling-related functions in women with benign breast tumor.
