The toxic effects of the combinations of amphotericin B (AmB) and actinomycin D or AmB and 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea were measured against the human promyelocytic leukemia cells HL-60. The toxicities of both drug combinations were greater than the additive toxicity of each of the drugs used singly, but the exact conditions under which synergism was achieved differed for each ...

Three umami substances (glutamate, 5'-inosinate, and 5'-guanylate) were found by Japanese scientists, but umami has not been recognized in Europe and America for a long time. In the late 1900s, umami was internationally recognized as the fifth basic taste based on psychophysical, electrophysiological, and biochemical studies. Three umami receptors (T1R1 + T1R3, mGluR4, and mGluR1) were identifi...

Fludarabine-containing combinations have additive cell killing against leukemic blasts in vitro. It has also been shown that imatinib mesylate combined with fludarabine or cladribine had an additive effect on CML CFU-GM cells. In this regard, we aimed to investigate the effect of fludarabine-imatinib mesylate combination against CML blastic phase cell lines K562 and Meg-01. XTT test was perform...

Propolis is a natural resinous substance collected by bees from tree exudates and secretions. Its antimicrobial activity has been investigated and inhibitory action on Staphylococcus aureus growth was evaluated. The in vitro synergism between ethanolic extract of propolis (EEP) and antimicrobial drugs by two susceptibility tests (Kirby and Bauer and E-Test) on 25 S. aureus strains was evaluated...

OBJECTIVE To study the synergism between neuropeptides and lithium ions. MATERIAL AND METHODS An experimental model of stroke (chronic bilateral occlusion of the common carotid arteries in rats), neuronal culture studies, histomorphological analyses, determination of micronutrient profile of brain substrates were used. RESULTS A complex of experimental studies revealed that the effect of ce...

the aim of this investigation was to assess the in vitro interaction of two antifungal agents, econazole-nitrate and chelerythrine, against ten fluconazole-resistant clinical isolates and one atcc type strain 10231 of candida albicans. the checkerboard microdilution method was performed according to the recommendations of the national committee for clinical laboratory standards, and the results...

objective(s): to evaluate the in vitro interaction between different extracts of thymbra spicata l. and certain antimicrobial drugs of different mechanisms, including ampicillin, cefotaxime, amikacin and ciprofloxacin. this study was performed against multidrug-resistant strains of staphylococcus aureus and klebsiella pneumoniae. materials and methods: evaluation of antibacterial activity and s...

accelerating wound healing is now considered as a principle clinical treatment and increasing the quality and speed of healing which has always been emphasized by the scientists. propolis and honey are natural bee products with wide range of biological and medicinal properties. this study was aimed to determine the synergistic effect of honey and propolis in wound healing of rat skin. a total o...
