the purpose of this study is determining of some immunity and blood serum parameters in brood stock and grower fish before and after of stripping to evaluate the effect of breeding physiological changes on immunity and serum indexes. in this study 15 male trout fish (oncorhynchus mykiss) including 5 in the stage of grower, 5 before stripping and 5 after stripping randomly were considered. blood...

Objective: To study the analgesic effect of Caryophyllus aromaticus (flower buds) by formalin test in albino rats. Materials & Methods: Albino rats of either sex were taken and divided into 7 groups with 6 animals in each for central and peripheral analgesic activity by formalin test. 5% formalin is injected into the right dorsal surface of a hind paw of rat after half an hour of drug administr...

Carnation (Dianthus caryophyllus L.) cv. Yellow Candy flowers were treated with ethanol solution (4%) in the absence or presence of 1 or 10 mM L-methionine, or ethanol or acetaldehyde solution (0.05%), in the absence or presence of 1 mM aminocyclopropane carboxylic acid (ACC). Spermidine in petals was measured over time in flowers treated with 4% ethanol or distilled water. Ethanol treatment si...

A glutathione S-transferase-like gene, DcGSTF2, is responsible for carnation (Dianthus caryophyllus L.) flower color intensity. Two defective genes, DcGSTF2mu with a nonsense mutation and DcGSTF2-dTac1 containing a transposable element dTac1, have been characterized in detail in this report. dTac1 is an active element that produces reverted functional genes by excision of the element. A pale-pi...

The inhibitory effects of the cyclic olefin 2,5-norbornadiene (NBD) on ethylene action were tested in carnation (Dianthus caryophyllus L. cv White Sim) flowers. Treatment of flowers at anthesis with ethylene in the presence of 500 microliters per liter NBD increased the concentration of ethylene required to elicit a response (petal senescence), indicating that NBD behaves as a competitive inhib...

Temperature, an environmental factor affecting cut flowers' physiological state, is expected to affect scent emission. We investigated emission from carnation flowers of two types (Dianthus caryophyllus L.), exhibiting fruity (because methyl benzoate) and spicy eugenol) scents, at various temperatures (10°C, 15°C, 23°C, 28°C). Cut harvested on the day flower opening were used for analysis. Scen...

The effect of leaf extracts of Psidium guajava and Piper betle on prolonging vase life of cut carnation flowers was studied. "Carola" and "Pallas Orange" carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a "germicide" (leaf extracts of P. guajava and P. betle, 8-HQC, or a copper coin). Flowers tre...
