Asexual propagation through cuttings is an appropriate method used for most ornamental plants. Success in increasing the percentage of rooting, reducing root emergence and increasing proliferation efficiency depends on several factors like plant growth regulators, especially auxins. Rooting of Forsythia × intermedia is difficult and requires specific hormonal treatments and proper cultivation b...

barfabad river is one of the most important surface water resources in the west of iran which passes from the south of kerend and through the islamabad city and receives high volume of human and industrial sewage. for assessing the water quality of the river, 8 stations were chosen and 72 samples were taken during 9 months from april 1997 to january 1998 and were analysed according to the stand...

The effect of Positive End Expiratory Pressure (PEEP) on the hepatic elimination of low to moderate extraction ratio drugs has not been clearly defined. We prospectively investigated the effect of PEEP on the clearance of theophylline in 30 (20 males and 10 females) intubated critically ill adult patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). The Mean (±SD) age ...

the abscission of alstroemeria petals is the serious problem at the industry of cut flowers of this plant. in this study, cut alstroemeria cv. bridal flowers were pulsed with solutions containing natural essential oil carvacrol, gibberellic acid and benzyladenine (50 and 100 mg l-1), -5-sulfosalicylic acid (1 and 1.5 mm) and sucrose (5 and 10%) for 24 hours. the distilled water was used as cont...

PURPOSE To study the effect of a nitric oxide synthase inhibitor on tissue circulation in the optic nerve head (ONH) of conscious rabbits. METHODS N(G)-nitro-L-arginine methyl ester (L-NAME) (1, 10, or 100 mg/kg), D-NAME (10 mg/kg), or physiological saline was administered intravenously to albino rabbits. A quantitative index of blood velocity, the normalized blur (NB), was measured in the ON...

OBJECTIVES Xanthorrhizol, isolated from the methanol extract of Curcuma xanthorrhiza Roxb., was investigated for its anticandidal activity using six Candida species. METHODS The in vitro susceptibility tests for xanthorrhizol were carried out in terms of MIC and minimal fungicidal concentration (MFC) using the NCCLS M27-A2 broth microdilution method. Time-kill curves were determined to assess...
