Abstract Background The present study was designed to investigate the therapeutic effects against oxidative stress and alleviative effects of Peganum harmala seeds (PH) in rats with Complete Freund’s Adjuvant (CFA) induced arthritis. Methods The extract was evaluated for its phytoconstituents, antiarthritic and antioxidant properties. The action of chloroform (PHC) and ethanolic (PHE) extracts of PH was evaluated in adult Lewis rats (150-200 g).with CFA induced arthritis. Arthritic rats received PH extracts 100 mg/kg orally for 28 consecutive days (Prophylactic treatment) and from 14th day of CFA injection (Therapeutic treatment). Results PHE significantly suppressed the arthritis severity in rats than PHC in 28 days. All complications shown significant reduction (p< 0.05) in arthritic rats including paw volume (63.09%), body weight loss, decreased locomotor activity, erythrocyte sedimentation rate and synovial/hepatic tissues lipid peroxidation and increase in cellular antioxidants superoxide dismutase (U/mg) activities and hemoglobin counts. The results showed the presence of alkaloids and flavonoids in PHE. Histology and radiographic analysis of arthritic ankle joints indicated abnormal changes. Marked reduction in inflammation and arthritic changes were observed after treatment with PHE. Conclusion Therefore, the investigation suggests that PHE at 100 mg/kg will be useful in the management of rheumatoid arthritis complications which may possibly be due to boosting the intracellular antioxidant defense.

Background: Growing evidence has shown that the apoptosis of cells plays an important role in the advancement of the Diabetic nephropathy (DN). Objectives: This study attempted to discover the therapeutic potential of Peganum harmala leaf extract in the apoptosis of diabetic kidney disease. Methods: In the present experimental research, 32 male Wistar rats were studied, and diabetes was induced by streptozotocin (STZ) (65 mg/kg). The animals were randomly divided into four groups (n=8, in each group) as follows: control, diabetic, control+leaf extract, diabetic+leaf extract. For our purposes, the methanolic extract of P. harmala leaves (150 mg/kg) was given by gavage for 28 days. Flow cytometry and real-time polymerase chain reaction (PCR) analyses were utilized to determine the percentages of apoptotic cells. Also, histological alterations and blood biochemical parameters were evaluated. Results: The P. harmala leaf extract has a high amount of flavonoids (25.84%), a lower percentage of alkaloids (0.14%), and some antioxidant properties. Serum urea (P<0.001) and apoptosis (P<0.05) significantly elevated in diabetic rats relative to the control ones. The mean of fasting blood creatinine, urea, and albumin level was not significantly changed in diabetic+leaf extract rats as compared to the diabetic ones. Histopathological results also displayed that diabetic complications in the kidney could not be improved following treatment by the leaf extract of P. harmala. In addition, the leaf extract could not significantly reduce the apoptosis and caspase-3 expression compared to diabetics in renal cells. Conclusion: Based on our findings, the leaf extract of P. harmala is unable to inhibit apoptosis in the diabetic kidney model.

The objective was to determine the effect of Brassica oleracea var Botrytis "cauliflower" inflorescences on cachectic syndrome in Mus musculus var. swiss with induced cancer. Cachectic syndrome is characterized by progressive loss of body weight, anorexia, asthenia, immunosuppression and metabolism of carbohydrates, lipids and proteins, with loss of muscle and adipose tissue. It used dry cauliflower inflorescence extract (ESC) and male mice 35-45 g with induced cancer, divided into groups: G1 untreated control, G2 and G3 treated with ESC, doses 10 and 20mg/kg/bw/vo and G4 treated with quercitin, dose 7.14mg/Kg/bw/vo for 90 days. Some manifestations of cachectic syndrome were determined. It was observed that G1 had thinning and progressive increase in alopecia, asthenia and conjunctival xerosis due to energy and metabolic imbalance compared to G2, G3 and G4 that had higher body weight and fewer cachectic manifestations, being significant by time and treatment group (P<0.01). It has been reported that cauliflower contains flavonoids quercitin and kaemferol, with anti-inflammatory properties for its action on cyclooxygenase, lipooxygenase, interleukins and chemosins, with antioxidant properties on intracellular glutathione, in redox reactions and favoring the expression of caspases in cell apoptosis. Therefore, it is concluded that cauliflower prevents body weight loss and decreases cachectic syndrome because it contains kaempferol and quercitin that act synergistically with anti-inflammatory, antioxidant and anticancer properties.

Antirhea borbonica (A. borbonica) is an endemic plant from the Mascarene archipelago in the Indian Ocean commonly used in traditional medicine for its health benefits. This study aims (1) at exploring polyphenols profiles from two types of extracts—aqueous (herbal infusion) and acetonic (polyphenol rich) extracts from A. borbonica leaves—and (2) at evaluating their potential toxicity in vivo for the first time. We first demonstrated that, whatever type of extraction is used, both extracts displayed significant antioxidant properties and acid phenolic and flavonoid contents. By using selective liquid chromatography–tandem mass spectrometry, we performed polyphenol identification and quantification. Among the 19 identified polyphenols, we reported that the main ones were caffeic acid derivatives and quercetin-3-O-rutinoside. Then, we performed a Fish Embryo Acute Toxicity test to assess the toxicity of both extracts following the Organisation for Economic Cooperation and Development (OECD) guidelines. In both zebrafish embryos and larvae, the polyphenols-rich extract obtained by acetonic extraction followed by evaporation and resuspension in water exhibits a higher toxic effect with a median lethal concentration (LC50: 5.6 g/L) compared to the aqueous extract (LC50: 20.3 g/L). Our data also reveal that at non-lethal concentrations of 2.3 and 7.2 g/L for the polyphenol-rich extract and herbal infusion, respectively, morphological malformations such as spinal curvature, pericardial edema, and developmental delay may occur. In conclusion, our study strongly suggests that the evaluation of the toxicity of medicinal plants should be systematically carried out and considered when studying therapeutic effects on living organisms.

Licorice and dried ginger decoction (Gancao-ganjiang-tang, LGD) is used for nausea and anorexia, accompanied by excessive sweating in Traditional Chinese Medicine. Herein, we investigated the therapeutic effects of LGD using the activity-based anorexia (ABA) in a mouse model. Six-week-old female BALB/c AnNCrl mice were orally administered LGD, water, licorice decoction, dried ginger decoction, or chronic olanzapine, and their survival, body weight, food intake, and wheel activity were compared in ABA. Additionally, dopamine concentration in brain tissues was evaluated. LGD significantly reduced the number of ABA mice reaching the drop-out criterion of fatal body weight loss. However, LGD showed no significant effects on food intake and wheel activity. We found that in the LGD group the rise of the light phase activity rate inhibited body weight loss. Licorice or dried ginger alone did not improve survival rates, they only showed longer survival periods than chronic olanzapine when combined. In addition, LGD increased the dopamine concentration in the brain. The results from the present study showed that LGD improves the survival of ABA mice and its mechanism of action might be related to the alteration of dopamine concentration in the brain.

Chronic Inflammatory Condition

Abstract Background Ulcerative colitis (UC) is a chronic inflammatory condition with no known medical cure. 5-Aminosalicylic acid (5-ASA [mesalazine]) represents the cornerstone of first-line therapy for mild-to-moderate UC. Sulfasalazine (SASP) is the original agent in this class of drugs. Meta-analyses of patients with mild-to-moderately active UC comparing 5-ASA to placebo showed 5-ASA to be significantly superior to placebo. However, about two-thirds of patients treated with 5-ASA fail to enter clinical remission. It is therefore most important to identify strategies to accelerate and maximise the therapeutic effects of 5-ASA. Therapeutic intervention against NFκB activation is a useful strategy for treatment of UC. The 4-alkanoylaminobenzamide PM0503 inhibits the breakdown of the NFκB inhibitor IκBβ, and SASP/5-ASA inhibits the breakdown of IκBα. This elicited a hypothesis of a possible synergistic action and converging effect on NFκB signalling. In the present study, we investigated the effect of combining SASP/5-ASA with PM0503 in experimental colitis. Methods SASP and PM0503 alone or in combination were administered for 5 days to Balb/c mice with colitis triggered by 5% dextran sulphate sodium (DSS). Blood in the stool, stool consistency and body weight loss were evaluated daily on a 0–4 point scale. The disease activity index (DAI) was calculated by summarising the total score of these three parameters. Results Addition of 5% DSS in the drinking water for 5 days produced reproducible symptoms of colitis. PM0503 was shown to inhibit DSS induced colitis by reducing mean DAI at day 5 from 6.9 in controls to 1.7 (a 75% decrease). Mean DAI recorded with SASP treatment at optimal doses in the same series of experiments was 4.4 (a 36% decrease). Furthermore, and most important, lower doses of PM0503 acted synergistically with SASP in ameliorating DSS-induced disease severity. The combination of PM0503 and SASP using suboptimal doses having minimal beneficial effects as monotherapies, showed more than 50% disease inhibition at day 5. In addition, no toxicity was observed with PM0503 alone or in combination with SASP. Conclusion Our findings offer a preclinical rationale for simultaneous coadministration of PM0503 and a 5-ASA agent such as SASP or 5-ASA as first-line treatment for patients with UC.

Ginger has been proven to possess various therapeutic effects, including antibacterial, anticancer, anti-inflammatory, and antioxidant effects. However, data on the comparison of ginger antioxidant activity with that of other natural products are still lacking. This study aimed to analyse and compare the antioxidant properties of two types of Malaysian ginger extracts (GE1 and GE2) with that of selected natural products. The antioxidant activities were measured by 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and ferric reducing antioxidant power (FRAP) assays, while cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfonyl)-2H-tetrazolium (MTS) assay. The order of the DPPH scavenging activities was as follows: vitamin C > palm tocotrienol-rich fraction (TRF) > á-tocopherol > N-acetylcysteine (NAC) > Ficus deltoidea > butylated hydroxytoluene (BHT) > Centella asiatica > GE2 > GE1 > Moringa oleifera > Kelulut honey; the order of the mean FRAP value was as follows: NAC > á-tocopherol > BHT > TRF > Ficus deltoidea > Moringa oleifera > GE2 = GE1 > Centella asiatica > Kelulut honey. The viability assays showed that both ginger extracts significantly increased the percentage of viable cells (p < 0.05). In conclusion, neither of the ginger extracts was cytotoxic toward cells and both possessed comparable antioxidant properties, indicating their potential for ameliorating oxidative stress.

Abstract Background We have demonstrated that endometrial regenerative cells (ERCs) are mesenchymal-like stromal cells and can attenuate experimental colitis, however, its underlying mechanism needs further investigation. Dickkopf-1 (DKK1), a glucoprotein secreted by mesenchymal stromal cells (MSCs), is a classical inhibitor of Wnt/β-catenin pathway which is closely associated with the development of colitis. Therefore, the objective of this study was to investigate whether ERCs could also secret DKK1, and whether the downregulation of DKK1 (DKK1low-ERCs) would enhance the therapeutic effects of ERCs in attenuation of experimental colitis. Methods BALB/c mice were given 3% dextran sodium sulfate (DSS) for 7 consecutive days and free tap water for 3 days sequentially to induce experimental colitis. Unmodified ERCs, IL-1β-treated ERCs (DKK1low-ERCs) and glucocorticoid-treated ERCs (DKK1high-ERCs) were injected (1 million/mouse/day, i.v.) on day 2, 5 and 8 respectively. Colonic and splenic samples were harvested on day 10 after DSS-induction. Results It was found that DKK1low-ERC treatment markedly attenuated colonic damage, body weight loss and colon-length shortening in colitis mice. Compared with other treatments, cell populations of CD4+IL-4+Th2, CD4+CD25+FOXP3+Treg, and CD68+CD206+macrophages in spleens were also significantly upregulated in DKK1low-ERC group (p < 0.05). In addition, lower expression of pro-inflammatory (TNF-α and IFN-γ), but higher levels of anti-inflammatory cytokines (IL-4 and IL-10) and β-catenin were detected in colons in DKK1low-ERC group (p < 0.01 vs. other groups). Conclusions DKK1low-ERCs display augmented immunoregulatory ability and therapeutic effects in DSS-induced colitis.

Topicality. In Ukraine, the number of patients with diabetes is growing rapidly, it ranks the 4th in the structure of diseases of the endocrine system, and it is one of the main causes of incapacitation and disability among the population and takes the second place by the number of deaths. Polyphenolic extracts from leaves of the heather (Ericaceae) family, in particular blueberries, cranberries and bearberry, in the previous studies demonstrated the presence of antioxidant, hypoglycemic and lipotropic properties. However, the pharmacological activity of extracts from cranberry leaves has not been sufficiently studied. Aim. To study the effect of polyphenolic extracts from cranberry leaves on the processes of LPO and the state of the antioxidant defense in the liver and serum in rats with the experimental insulin resistance. Materials and methods. The study was performed on white outbred male rats weighing 180 ± 15 g, kept in the vivarium of the NUPh. Insulin resistance was induced by keeping animals on a high fructose diet for 6 weeks according to the recommendations. The extracts were administered intragastrically in the dose of 200 μg/100 g of the body weight from the fourth week of the experiment for 14 days. The POL activity was assessed by the level of TBA reactants, diene conjugates and conjugated trienes in the liver and serum. The state of the antioxidant defense was assessed by the level of reduced glutathione, as well as the activity of catalase and superoxide dismutase. Indicators were determined by the spectrophotometric method. Results and discussion. The development of the experimental resistance was accompanied by an increase in LPS activity in the liver and serum of rats. In the serum of animals with IR the content of primary products of LPO increased in 1.75 times, the content of triene conjugates in 1.7 times, respectively, while the content of TBA reactants in 1.61 times. The introduction of the polyphenolic concentrate from cranberry leaves was accompanied by a sharp decrease in the products of lipid peroxidation both in the eserum and liver to almost ascending levels. There was normalization of the activity of enzymes of the first line of the antioxidant defense compared to animals with insulin resistance due to the presence of plant flavonoids in the extract. Conclusions. Thus, the data obtained indicate that the polyphenolic extract from cranberry leaves exhibits antioxidant properties in the liver and serum of rats with the experimental insulin resistance. The polyphenolic extract also restored the antioxidant defense of cells and the body as a whole. The data obtained indicate the need for further research to create a new herbal medicine for use in the treatment of insulin resistance and diabetes.

One of the richest natural sources of resveratrol - the rhizome of Reynoutria japonica in East Asia is a well-known traditional herb (Hu zhang) used in various inflammatory diseases, infections, skin diseases, scald, hyperlipidemia. Although, it has been recently included in the European Pharmacopoeia, still in Europe is an untapped resource. Some of the therapeutic effects are likely to be influenced by its antioxidant properties and this in turn is frequently associated with a high stilbene content. However, some literatures suggested that other compounds than stilbenes may add to the total antioxidant capacity. Hence, the aim of this research was to examine rhizomes of R. japonica and less studied, morphologically similar species, R. sachalinensis and R. x bohemica for their phytochemical composition and antioxidant activity and to clarify the relationship between the antioxidant activity and compounds by statistical methods. HPLC/UV/ESI-MS studies of three Reynoutria species revealed 171 compounds comprising stilbenes, carbohydrates, procyanidins, flavan-3-ols, anthraquinones, phenylpropanoids, lignin oligomers, hydroxycinnamic acids, naphthalenes and their derivatives. Our studies confirmed the presence of procyanidins with high degree of polymerization, up to decamers in the rhizomes of R. japonica and brings new data on the presence of these compounds in other Reynoutria species. A procyanidin trimer digallate was described for the first time in the studied plants. Moreover, we suggested a presence of new for these species, dianthrone glycosides and previously unrecorded phenylpropanoid disaccharide esters and hydroxycinnamic acid derivatives, mainly in R. sachalinensis. Furthemore, compounds tentatively annotated as lignin oligomers were observed for the first time in studied species. The rhizomes of all Reynoutria species exhibited strong antioxidant activity. Statistical analysis demonstrated that proanthocyanidins should be considered as important contributors to the total antioxidant capacity.
