Callus induction and regeneration of fennel from embryo explants were stabilized in the presence of cefotaxime antibiotic and different plant growth regulators (PGRs). The experiments were conducted under a factorial experiment, based on a completely randomized design (CRD). Genotypes; Fasa, Meshkinshar and Hajiabad were applied under different concentration of cefotaxime (0 and 100 mg l-1...

To assess the cardiovascular actions of magnesium in neurally intact animals, magnesium chloride (1-4 mM/min) administered i.v., producing a peak arterial magnesium level between 4.7 and 7.2 mg/dl, was given to alpha-chloralose-anesthetized, open-chest dogs. Magnesium lowered heart rate by 36 +/- 11 beats/min (P less than .05), cardiac output by 0.7 +/- 0.2 liters/min (P less than .05), left ve...

The postharvest life of cut Eustoma grandiflorum flowers is limited in open flowers. Therefore a factorial experiment based on a completely randomized design with ascorbic acid (AsA) at 4 levels (0, 100, 200, 300mg L-1) and citric acid (CA) at 3 levels (0, 100, 200 mg L-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. Results indicated that a significa...

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...

Phosphodiesterase-5 (PDE-5) inhibitors induces vasodilation in several organs by blocking cyclic GMP (guanosine monophosphate) degradation. However, the existence of alternative mechanism of action in case of an impaired nitric oxide (NO) system remains controversial. Previous studies suggested that decreased NO bioavailability may result in the downregulation of klotho expression, but the rela...

Aglaonema widuri is an evergreen and indoor ornamental plant. This study aimed to investigate the effect of some plant growth regulators on micropropagation of A. widuri. A protocol was developed for high frequency in vitro multiplication of ...

Linum usitatissimum L is traditionally used for relief of pain and inflammation. In this study, the analgesic and anti-inflammatory effects of this plant were evaluated. Xylene test was used for anti-inflammatory evaluation in which 48 mice were randomly designated into 6 groups of 8 each including: control, dexamethasone as positive control (15 mg/kg), and experimental groups (42, 85, 170, and...
