Airway inflammation by eosinophils, neutrophils and alveolar macrophages is a characteristic feature of asthma that leads to pathological subepithelial thickening and remodeling. Our previous study showed that oxidative stress in airways resulted in eosinophilia and epithelial apoptosis.
BACKGROUND
The molecular and functional basis of allergen-induced inflammation seen in atopic dermatitis (AD) remains undefined.
OBJECTIVE
The objective of this study is to establish a murine model to dissect the pathological mechanisms of inflammatory reactions leading to the development of
With the use of a percoll gradient separation procedure, eosinophils of individuals with asthma and with allergy could be separated into normal- and low-density cell fractions. The presence of low-density eosinophils possibly reflects an ongoing process of activation of these cells induced by the
Glutathione S-Transferases Omega Class 1 (GSTO1-1) is a unique member of the GST family regulating cellular redox metabolism and innate immunity through the promotion of LPS/TLR4/NLRP3 signaling in macrophages. House Dust Mite (HDM) triggers asthma by promoting Type 2 responses and Chronic airway inflammation is a hallmark of asthma, which is an immune-based disease. We evaluated the ability of saucerneol D, a tetrahydrofuran-type sesquilignan isolated from Saururus chinensis, to regulate airway inflammation in an ovalbumin (OVA)-induced airway inflammation model. Furthermore,
BACKGROUND
Drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DIHS/DRESS) is a rare and severe adverse drug reaction with an associated mortality of 10-20%. Clinical worsening despite discontinuation of the culprit drug is considered a characteristic
Interrelationships among induction of cytochrome P-450 (CYP) 1A1/2, decrease in connexin 32 (Cx32), and liver tumor-promoting activity by beta-naphthoflavone (BNF) in the promotion stage were examined in a 2-stage liver carcinogenesis model. A total of 20 male Fischer 344 rats were initiated with a
Homeostasis of the reduction-oxidation (redox) state is critical to protection from oxidative stress in the lungs. Therefore, the lungs have high levels of antioxidants, including glutathione, heme oxygenase, and superoxide dismutase. The numbers of inflammatory cells -- particularly eosinophils --
The leading cause of drug-induced liver injury in the developed world is overdose with N-acetyl-p-aminophenol (APAP). A comparative metabonomic approach was applied to the study of both xenobiotic and endogenous metabolic profiles reflective of in vivo exposure to APAP (300 mg/kg) and its structural
Owing to its lipophilic property, carbon tetrachloride (CCl4) is rapidly absorbed by both the liver and brain. We investigated the protective effects of crocin against brain damage caused by CCl4. Fifty rats were divided into five groups of ten: control, corn oil, crocin, CCl4 and CCl4 + crocin.
Hepatic histologic changes and induction of mixed function oxidases were examined and compared after administration to the chick embryo of four highly purified polychlorinated biphenyl (PCB) congeners: 3,4,3',4'-tetrachlorobiphenyl (TCB) and 3,4,5,3',4',5'-, 2,4,5,2',4',5'-, and
To examine the relationship between the decrease in connexin 32 (Cx32) and induction of P450 isozymes in the early phase of clofibrate hepatocarcinogenesis, a total of 20 male F344 rats were initiated with a single intraperitoneal injection of 150 mg/kg of diethylnitrosamine (DEN) or given the
We have shown that a single dose of streptozotocin (STZ) (50 mg/kg body weight) injected into rats caused significant changes in some antioxidant enzyme activities, such as glutathione peroxidase, glutathione reductase, glutathione-S-transferase, glucose-6-phosphate dehydrogenase, and
OBJECTIVE
To determine the chemical structure of a contaminant, X1, previously found in eosinophilia myalgia syndrome case-implicated 5-hydroxytryptophan (5-OHTrp), and also present in over-the-counter (OTC) commercially available 5-OHTrp.
METHODS
Case-implicated 5-OHTrp as well as 6 OTC samples
In male F344 rats pretreated with diethylnitrosamine (DEN), subsequent administration of clofibrate increased the proportion of eosinophilic foci, to become the most abundant type, and reduced numbers of basophilic, clear and vacuolated foci, the total not being changed. A similar shift towards
