In this study, the effect of different extracts of Centaurea pterocaula were evaluated on 6 mm wound created by punch biopsy on the rat back. The leaves of the plant were powdered and extracted with distilled water, methanol, n-hexane and ethyl acetate. Extracts were obtained in the form of pomade with vaseline and applied topically to the wounds. The wound measurements performed on day 0, 2, 4, 6, 8, 10 and 12 and the histo-pathological examination performed on day 12. The n-hexane extract had an accelerating effect on wound healing and made a positive contribution to the healing process. In conclusion, C. pterocaula has a promising future for new drug development studies by its wound healing property.

This study aimed to investigate the anti-tumor effects of compound 34 on MCF-7 cells in vitro, and explore its mechanisms. MTT results showed that compound 34 selectively inhibited estrogen receptor-positive cells proliferation. Hoechst 33342 staining showed nuclear pyknosis, nuclear debris associated with apoptotic bodies. JC-1 staining showed the loss of mitochondrial membrane potential. Although compound 34 increased intracellular reactive oxygen species (ROS), compound 34-induced apoptosis was not prevented by pretreatment with ROS scavengers. Western blotting showed apoptosis-related protein like cytochrome c and cleaved PARP protein increased. Furthermore, docking studies exhibited that compound 34 could bind into ERα. In summary, compound 34 selectively inhibited estrogen receptor positive cells proliferation and induced apoptosis in MCF-7 cells via ROS-independent intrinsic apoptosis in MCF-7 cells. It may be a potential targeted drug of estrogen receptor for therapeutic application of breast cancer. Video Clip of Methodology: Assay of Cell Proliferation: 5 min 5 sec Full Screen Alternate

This study explores the pharmacological basis for the folk use of Fagonia indica in constipation using in vivo and in vitro assays. The crude extract of F. indica contained tannins, saponins, anthraquinones, alkaloids, flavonoids, glycosides and phenols. The administration of F. indica extract (100 and 300 mg/kg) to mice caused a partially atropine-sensitive 35 and 42.6% laxation, respectively, similar to ursolic acid which showed 22 and 36% laxation at 10 and 30 mg/kg, respectively. In loperamide-induced constipation mice, F. indica (27.3 and 34.6%) and ursolic acid (15 and 28%) also displayed laxative effects at the aforementioned doses. In mice and rats ileum, F. indica, its fractions (ethyl acetate, aqueous) and ursolic acid produced atropine-sensitive stimulatory effects, while in rats ileum, F. indica and aqueous fraction showed partially atropine-sensitive effects. F. indica and ursolic acid possess laxative and species-specific gut stimulant effects predominantly involving the activation of muscarinic receptor, thus eliciting its folk use in constipation.

An attempt has been made to investigate the role of Zaleya decandra on the survival of HCT colon cancer cells in vitro. The cell viability and apoptosis were assessed using MTT assay and acridine orange/ethidium bromide staining, respectively. Mitrochondrial membrane permeability was assessed using rhodamine-123 staining. The activities of caspases were evaluated using ELISA kits. Treatment with Z. decandra extract increased the production of ROS in HCT cells and impaired the mitochondrial activity as evidenced by decreased reduction of tetrazolium salt and enhanced mitochondrial membrane permeability. The onset of apoptosis was evident in cells treated with the extact in acridine orange/ethidium bromide staining and was associated with elevated levels of initiator and effector caspases in the conditioned medium. In conclusion, Z. decandra treatment promoted the apoptosis of HCT colon cancer cells. Video Clip of Methodology: 6 min 53 sec: Full Screen Alternate

The methanolic extract of Citrus limetta leaves was estimated in the present study for antidepressant activity. This activity was evaluated by using the rat behavioral model i.e. forced swimming and tail suspension model for 14 days, with estimation of neurotransmitters in animals brain. The sedative effect was evaluated by actophotometer. The extract (200 mg/kg) administered orally showed significant (p<0.05) decrease in immobility time against the standard drug fluoxetine (20 mg/kg, i.p), and imipramine (15 mg/kg, i.p.) respectively but no significant reduction was found in the locomotor activity against diazepam (2 mg/kg, i.p.). In depression, the brain reflected low monoamines level like release of norepinephrine, dopamine and serotonin but 14 days after successive administration of the extract, their levels were significantly increased. In conclusion, C. limetta showed significant antidepressant activity. Video Clip of Methodology: Forced swimming test: 6 min 17 sec: Full Screen Alternate

The anxiolytic and antidepressant like effects of Salvia officinalis extract (50, 100 and 200 mg/kg) were evaluated using marble burying, forced swimming and open-field tests in intact and hippocampal lesioned rats. Additionally, S. officinalis was evaluated on rat's memory using conditioned learning test. and we screened the methanolic extract for anti-oxidant activity, phytochemical and high performance liquid chromatography analyses. The administration of sage extract showed a significant reduction of immobility time in lesioned and intact animals during the forced swim test and anxiolytic effect in marble burying test. In the case of conditioned learning paradigm, memory enhancement was observed in sage treated group which indicates a cognition improvement. These activities seem to be related to the anti-oxidant capacity and the phytochemicals (phenolic, flavonoid, and tannin) detected into the extract of S. officinalis. The findings show that the methanolic extract of sage possess antidepressant-like effect, anxiolytic activity and also may contain bioactive compounds that stimulate learning in rat.

Evaluating the effect of herbal extracts has been always interesting for cancer researchers considering that these natural materials could be suitable sources for finding new anti-cancer agents. In the present study, Acroptilon repens methanol extract had been evaluated for its cytotoxic effects in two human breast cancer cell lines, MCF-7 and MDA-MB-468, using MTT assay. The apoptosis potential had also been evaluated using annexin-V/propidium iodide assay, Hoechst 33258 staining and evaluating the cell cycle with flow cytometery. The MTT results showed cytotoxicity with IC50 values of 69.2 and 32.6 μg/mL for MCF-7 and MDA-MB-468 cells, respectively. The results of the apoptosis assays confirmed the apoptosis potential of the plant extract in the breast cancer cell lines suggesting A. repens for further cancer studies.

This study was conducted to investigate the neuroprotective effect of Citrus aurantium essential oil on hippocampal injury induced by transient global cerebral ischemia and reperfusion in rat. In total 50 rats were randomly assigned into five groups; control, sham, ischemia, and essential oil-treated (50 or 75 mg/kg) rats. Ischemia was induced by occlusion of the carotid artery for 30 min. Spatial memory, passive avoidance learning, anti-oxidant capacity, and lipid peroxidation during ischemia/reperfusion were evaluated. The compounds of the essential oil were analyzed by gas chromatography/mass spectrometry. Induction of ischemia/reperfusion caused a decline in learning and passive avoidance memory in rats. C. aurantium exerted protective effects on the spatial memory, passive avoidance learning, anti-oxidant capacity, and lipid peroxidation during ischemia/reperfusion in animals. The main compounds of the essential oil were camphor (45.9%), thymol (11.2%), linalool (6.6%), carvacrol (6.3%) and borneol (2.9%). The essential oil with anti-oxidant compounds significantly decreased the symptoms of ischemia/reperfusion injury.

Herein the antidepressant-like effect of theaflavin-3-gallate, a plant polyphenolic compound in 1-methyl-4-phenyl pyridinium-induced neuronal injury in N2a cells used as an in vitro model of depression as well as in vivo. The results from MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) and lactic dehydrogenase assay revealed that theaflavin-3-gallate exerted a neuroprotective effect in N2a cells. Treatments with mixtures of 1-methyl-4-phenyl pyridinium (20 µM) and four concentration levels of theaflavin-3-gallate increased cell viability from 23.3 to 79.6% while lactic dehydrogenase leakage value decreased from 63.2 to 23.4 U/L. Fura-2-acetoxymethyl ester assay for Ca2+ concentration measurement revealed that different doses of theaflavin-3-gallate or fluoxetine (20 µM) reduced the intracellular Ca2+ overloading in N2a cells induced by 1-methyl-4-phenyl pyridinium. Inverted phase microscopy showed that theaflavin-3-gallate induced neurite outgrowth in 1-methyl-4-phenyl pyridinium-induced neurotoxicity in N2a cells. Theaflavin-3-gallate could significantly reduce the immobility time of mice in both forced swimming test and tail suspension test.Video Clip of Methodology:MTT Assay: 3 min 38 sec Full Screen Alternate
