Whole-mount airway preparations isolated from the lungs of mice treated by intraperitoneal injection of naphthalene and allowed to recover for 5 days were examined for the distribution and abundance of solitary pulmonary neuroendocrine cells (PNECs) and neuroepithelial bodies (NEBs) along the main
An auxin-binding protein can be solubilized from microsomal membranes of Zea mays using either Triton X-100 extraction of the membranes or buffer extraction of the acetone-precipitated membranes. This paper describes the properties of the binding protein solubilized by these two methods. The binding
Quinone metabolites of naphthalene (NAP) are known to produce lipid peroxidation. However, the ability of naphthalene to induce oxidative stress in experimental animals has not been extensively investigated. Furthermore, the effects of vitamin E succinate [(+)-alpha-tocopherol acid succinate; VES]
Airway epithelial damage and repair represents a novel therapeutic target in asthma and chronic obstructive pulmonary disease. An established mouse model of airway epithelial damage involves the Clara cell cytotoxicity of parenterally administered naphthalene, an important environmental toxicant
The effect of two plant growth regulators, alpha-naphthalene acetic acid (NAA) and thidiazuron (TDZ) on the growth of sweet corn (Zea mays), cowpea (Vigna sinensis) and cucumber (Cucurmis sativus) seedling planted in 1-100 mg kg(-1) of endosulfan sulfate spiked sand was investigated. Endosulfan
Naphthalene is a bicyclic aromatic compound that is widely used in various domestic and commercial applications including lavatory scent disks, soil fumigants and moth balls. Little information is available regarding the mechanism of naphthalene toxicity. We have assessed the oral, low dose (0.05
The purpose of this study was to define the sites of cytotoxicity within the respiratory tract (nasal cavity and tracheobronchial airway tree) resulting from administration of naphthalene, an organic chemical whose cytotoxic properties require metabolic activation via the cytochrome P-450
Recent evidence suggests that epithelial-mesenchymal transition (EMT) is involved in the pathogenesis of airway obstructive diseases, such as chronic obstructive pulmonary disease, asthma and bronchiolitis obliterans syndrome after lung transplantation. However, whether EMT occurs in an experimental
The aim of this study was to investigate the possible protective effects of aqueous garlic extract (AGE) against naphthalene-induced oxidative changes in liver, kidney, lung and brain of mice. Balb/c mice (25-30 g) of either sex were divided into five groups each comprising 10 animals. Mice received
This study presents a model to simulate the organic substance concentrations in corn grains assuming that the substances in soil solution are absorbed via the transpiration stream by plants growing in soils fertilized with sewage sludge (SS). The model was applied and validated using soil and corn
OBJECTIVE
To investigate protective effect of Coleus aromaticus leaf extract against naphthalene induced hepatotoxicity in rats.
METHODS
Eighteen male rats were divided into three groups. Group I rats were treated as control. Group II rats were intraperitoneally administered with naphthalene (435
Repeated exposures to the Clara cell cytotoxicant naphthalene (NA) result in target cell populations that become refractory to further injury. To determine whether tolerance occurs from specific adaptations favoring glutathione (GSH) resynthesis without broad shifts in cellular phenotype, mice were
Random bred CD-1 mice were used to evaluate the acute oral toxicity and subchronic toxicity of naphthalene administered in corn oil. The acute oral LD50 of naphthalene was 533 and 710 mg/kg in male and female mice, respectively. Subchronic toxicity was evaluated with 14- and 90-day daily oral gavage
The ability of the water-soluble protein extracts from Zea mais L. cv. PR32-B10 to degrade some representative polycyclic aromatic hydrocarbons (PAHs), has been evaluated. Surface sterilized seeds of corn (Zea mais L. Pioneer cv. PR32-B10) were hydroponically cultivated in a growth chamber under
In a search for membrane "docking proteins" interacting with Zea mays auxin-binding protein (ABP1) the binding of purified ABP1 to maize coleoptile plasma-membrane vesicles was investigated. Concentration-dependent, saturable binding of ABP1 to the membrane vesicles was observed in binding assays
