naphthalene/edema

A method for isolation and maintenance of the mouse lung ex vivo suitable for the study of the relationship between metabolism and toxicity is described. Physical, biochemical and morphological evaluations revealed that the lung is viable for up to 5 hr. No significant alterations in the

BACKGROUND Naphthalene is one of the abused inhalants. It has been associated with acute and chronic health problems. To the authors' knowledge, prenatal exposure to naphthalene has never been discussed in humans. METHODS The authors discuss a case of naphthalene-addicted pregnant women with

Hexabrominated naphthalenes (HBNs) have been identified as contaminants in the commercial PBB mixture, Firemaster. Similarities between polyhalogenated naphthalenes and polyhalogenated biphenyls, dibenzofurans, and dibenzo-p-dioxins with regards to structure and capacity to elicit certain

A series of 2,3-(alkylidenedioxy)naphthalene (5a-p) analogues of lonapalene (RS-43179, 1), a 5-lipoxygenase inhibitor currently under clinical investigation for the treatment of psoriasis, has been prepared and evaluated for topical inhibitory activity against arachidonic acid induced mouse ear

On the basis of previous observations that both 2,3-dihydro-2,2,3,3-tetrahydroxy-1,4-naphthoquinone (oxoline, 1) and 6-chloroisonaphthazarin (2) had demonstrated antipsoriatic activity in vivo, a series of structural derivatives of 2 were prepared and examined in the Scholtz-Dumas topical psoriasis

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common genetic defect and enzymopathy worldwide, affecting approximately 400 million people and causing acute hemolysis in persons exposed to prooxidant compounds such as menthol, naphthalene, antimalarial drugs, and fava beans. Mouse

The synthesis, biological evaluation, and structure-activity relationships of a series of 1-naphthols bearing carbon substituents at the 2-position are described. These compounds are potent inhibitors of the 5-lipoxygenase from RBL-1 cells and also inhibit bovine seminal vesicle cyclooxygenase.

SQ 26,490, (11 beta, 16 beta)-9-fluoro-1',2',3',4'-tetrahydro-11, 21-dihydroxypregna-1,4-dieno[16,17-b]naphthalene 3,20-dione hydrate (1 : 1), was a moderately potent inhibitor of edema formation in the rat. After extended topical application, SQ 26,490 totally inhibited edema formation without

Despite widespread exposure to military jet fuels, there remains a knowledge gap concerning the actual toxic entities responsible for irritation observed after topical fuel exposure. The present studies with individual hydrocarbon (HC) constituents of JP-8 jet fuel shed light on this issue. To mimic

Polycyclic aromatic hydrocarbons (PAHs) can cause a variety of effects in early life-stages of fish that have been chronically exposed as embryos, including mortality, deformities, and edemas. Mechanistic models of the chronic toxicity of complex mixtures of PAHs in fish have not been reported, with

JP-8 is the major jet fuel used by US Army and Air Force. The purpose of the present study was to investigate the percutaneous absorption of JP-8 across pig ear skin and human skin in vitro and to study the effect of JP-8 exposure on the skin barrier function and irritation in Yucatan minipigs. JP-8

In this study, we investigated the skin irritation, macroscopic and microscopic barrier alteration in vivo in rabbits from aliphatic and aromatic components of jet propellant-8 (JP-8) jet fuel. Macroscopic barrier properties were evaluated by measuring transepidermal water loss (TEWL), skin

Crude oils from distinct geographical regions have distinct chemical compositions, and, as a result, their toxicity may be different. However, developmental toxicity of crude oils derived from different geographical regions has not been extensively characterized. In this study, flounder embryos were

JP-8 is the major jet fuel used by US Air Force. JP-8+100 is a new jet fuel recently introduced by the US Air Force, which contains JP-8 plus three performance additives [butylated hydroxytoluene (BHT), metal deactivator (MDA) and 8Q405]. The purpose of the present study was to investigate the

As a part of ongoing studies in developing new potent anti-inflammatory and analgesic agents, a series of novel 6-methoxy naphthalene derivatives was efficiently synthesized and characterized by spectral and elemental analyses. The newly synthesized compounds were evaluated for their
