a completely randomized design (crd) with three replications was conducted at greenhouse of urmia university in 2013 to study the effect of different methyl jasmonate concentrations (0, 0.1 and 0.5 mm) on the activity of enzymes polyphenol oxidase, phenylalanine ammonia lyase, catalase, ascorbate peroxidase, guaiacol peroxidase and total protein content in basil. activity of the enzymes and tot...

The gametogenesis and the embryogeny of Sesamum indicum L. were reported by Nohara (1934). He observed the embryo sac formation but did not completed the study up to the stage of the embryo. However,. Johansen (1950) states that the embryogeny of the Pedaliaceae probably follows the Onagrad type, judging from the inadequate illustrations accompanied by the rather meager accounts of the embryoge...

In recent years, nanotechnology has gained serious attention for diagnosis, prevention and treatment roles. In this study we synthesized nanoceria or CeO2NPs (cerium oxide nanoparticles) and compared toxicity of cerium oxide powder in nano and bulk forms in two cancerous and one normal cell lines. The cell lines were cultured in a standard humidified incubator, at 37 °C in a 5% CO2 atmosphere, ...

OBJECTIVE To investigate the changes in the currents of voltage-dependent calcium channels (VDCCs) in smooth muscle cells of basilar artery in a rabbit model of subarachnoid hemorrhage (SAH). METHODS New Zealand white rabbits were randomly divided into five groups: sham (C), normal (N), 24 hours (S1), 48 hours (S2) and 72 hours (S3) after SAH. Non-heparinized autologous arterial blood (1 ml/k...

Ultrastructural changes in the exocrine pancreas 24, 48, 72 and 168 hours after a single intravenous injection of 4-hydroxyaminoquinoline-1-oxide (4-HAQO), at a dose of 14 mg.per kg., were observed in male rats. At 24 hours after administration, multiple focal degenerative lesion-like large vacuoles in the acini, and a decrease in zymogen granules with dilation of the rough endoplasmic reticulu...

OBJECTIVE We investigated the effects of hyperbaric oxygen (HBO2) and/or 5-fluorouracil (5-FU) on the proliferation and metastasis of human nasopharyngeal carcinoma (NPC) cell line CNE2Z and the underlying mechanisms involved. METHODS Nasopharyngeal carcinoma (NPC) CNE2Z cells were randomly divided into four groups: Group A: control group; Group B: 5-FU group; Group C: HBO2 group; Group D: 5-...

The renal effects of frusemide treatment in infants with respiratory distress syndrome shortly after birth and during the first three postnatal days were evaluated. Eighty five infants were randomly assigned to two groups. Forty two received three doses of intravenous frusemide (1 mg/kg) starting at age, mean (SD) 7.5 (4.1) hours and given at approximately 24 hour intervals. Forty three control...

PURPOSE To examine whether the activity of peripheral sympathetic nerves in animals with spinal cord injury can be controlled using therapeutic electrical stimulation. METHODS The spinal cords of 6 Wistar rats were severed at T12/T13 disk level and were given continuous therapeutic electrical stimulation. Microneurography was used to record sympathetic nerve activity at 24, 48, and 72 hours a...

BACKGROUND Transforming growth factor beta (TGF-beta) regulates hepatocyte proliferation and biosynthesis of the extracellular matrix. AIMS This study investigated alternations in sensitivity to TGF-beta1 and binding properties for ligand in hepatocytes and hepatic stellate cells (HSC) after CCl(4) administration. METHODS Plasma TGF-beta1 levels in rats after CCl(4) administration were dete...
