    varthemia iphionoides
    Opis:
    Varthemia iphionoides is a perennial plant that belongs to Asteraceae family. This study investigates the cytotoxic effect of V. iphionoides essential oil on breast (MCF7), prostate (PC3), and chronic myelogenous leukemia (K562) and normal human fibroblast cell lines using MTT assay and flow cytometric analysis. In addition, GC-MS of the oil was carried out. The IC50 values for PC3, MCF7, K562 and fibroblast were 145.3, 188.8, 87.88 and 173.3 µg/ml, respectively. V. iphionoides essential oil was most effective against K562. Flow cytometric results for IC50 dose of V. iphionoides oil on K562 cells showed 32.2 % apoptosis in 24 h. GC-MS analysis resulted in the identification of 25 compounds. 1,8-Cineole, borneol, and α-cadinol were the major constituents of V. iphionoides volatile oil. In conclusion, this study reveals for the first time the cytotoxic activity of V. iphionoides essential oil on K562 cell line which may occur through apoptosis induction.

    Opis:
    Natural polyphenolic compounds produced by plant exhibit many pharmacological effects including antioxidant, chemopreventive as well as anticancer properties. This study was conducted to investigate the effect of cynarin ( from Artichoke, Cynara scolymus) and isoliquiritin (from Licorice, Glycyrrhiza uralensis) on doxorubicin (positive control) cytotoxicity in different cell lines including normal (Fibroblasts MCR-5 and Myoblasts H9c2) and cancer (colorectal HCT-116 and hepatocellular HEP-G2) cell lines. The cytotoxic effect of doxorubicin, isoliquiritin and cynarin alone or in different combination was studied on cancer cell lines as well as normal cell lines. The results obtained indicated that both cynarin and isoliquiritin enhance the cytotoxicity of doxorubicin. Both cynarin and isoliquiritin also reduce the cardiotoxicity of doxorubicin on normal cardiac cell lines. The combination of the three compounds (cynarin, isoliquiritin and doxorubicin) result in decrease the cytotoxicity of doxorubicin, which may indicate the presence of interaction and/or antagonism effect between cynarin and isoliquiritin. Cynarin was found to enhance the growth of (HCT-116 and HEP-G2) this might suggest avoiding use of Artichoke in subjects’ susceptibility for these cancers. All results were evaluated using statistical path and showed significant findings. The mechanism of enhanced doxorubicin’s cytotoxicity by cynarin or isoliquiritin also require further investigation to explain the increasing and/or the decreasing effect of these polyphenolic compounds on cytotoxicity of doxorubicin. The current finding can help to start with safe minimum dose of two or three combination of compounds in the context of clinical trials and practice.

    Opis:
    Ononis spinosa (spiny restharrow) is a perennial herb that belongs to the Fabaceae family. Among several uses, the aerial parts of O. spinosa are used in traditional medicine for toothache. In this study, analgesic activity of the methanolic extract of leaves was studied. In writhing test, the 300 mg/kg and 600 mg/kg doses of O. spinosa extract produced 90.1% and 94.5% inhibition of abdominal cramps, respectively compared to 23.6% inhibition produced by 30 mg/kg diclofenac sodium. O. spinosa methanolic extract reduced the time of licking in early and late phases of formalin test. The inhibitory effect of O. spinosa extract was more pronounced in late phase. The lowest dose tested (300 mg/kg) of O. spinosa extract produced 81.0% inhibition compared to 50.5% inhibition in 30 mg/kg diclofenac sodium in the late phase of formalin test. This effect was not abrogated by glibenclamide, naloxone or atropine indicating that the action of O. spinosa in formalin test is not mediated by ATP-sensitive K+ channel, opioid or muscarinic receptors. In tail-flick and hot-plate tests, O. spinosa increased the latency time at 30 min and 150 min. Naloxone antagonized the action of O. spinosa in both tests suggesting an interaction with opioid receptor as a possible mechanism of O. spinosa in thermal pain models at the spinal and supraspinal levels. Phytochemical screening indicated the presence of phenolics, saponins, flavonoids, and terpenoids. Alkaloids, sterols, and anthraquinone glycosides were absent. HPLC analysis confirmed the presence kaempferol, apigenin and myricetin in the extract.

    Opis:
    The aim of study was to evaluate the release kinetics of domperidone maleate (DM) from immediate release (IR) tablets prepared by wet granulation method. Box behnken design (BBD) was used to optimize and evaluate the main, interaction and quadratic effects of independent variables i.e. crosslinked carboxymethyl cellulose (CMC) (X1), sodium starch glycolate (SSG) (X2) and starch (X3) on responses R2 of first order (YI) and β value of weibull model (Y2). Prepared tablets were characterized by various physical tests, in-vitro drug release, fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD) and differential scanning calorimetry (DSC). Accelerated stabilities studies were performed on optimized formulation D9. Y1 and Y2 were ranged from 0.9959 to 0.9994 and 0.041 to 0.912 respectively. β value of weibull model indicated the parabolic shape of dissolution curve. The quadratic model fit the data well and the resulting equations were used to predict the responses in the box behnken design. FTIR spectra showed the compatibility of DM with CMC and SSG. XRD presented diffraction lines indicates crystalline nature of drug. DSC thermograms indicated endothermic peak at 220 0C for DM. Stabilities studies revealed that no significant change in hardness, friability, disintegration time and dissolution release profile of DM. It is concluded that a combination of CMC and SSG can be used to enhance the dissolution and release kinetics of IR tablets of DM.
