To elucidate the role of N-phenylhydroxylamine (PHA, N-hydroxylated metabolite of aniline) in the selective toxicity of aniline to the spleen, dose-dependent studies were conducted with PHA in rats. Male Sprague-Dawley rats were given four doses each (1 dose/day) of 0.025, 0.05, 0.1, or 0.2 mmol/kg
9-(4'-Aminophenyl)-9H-pyrido [3,4-b] indole (aminophenylnorharman, APNH) is a novel mutagenic heterocyclic amine, produced by the reaction of norharman with aniline in the presence of S9 mix. In the present study, the maternal and developmental toxicity of APNH were investigated in ICR mice
In an attempt to elucidate the biochemical mechanism of acetaminophen-induced hepatic necrosis, the present study in hamsters was undertaken to evaluate the possible changes in lipid peroxidation and microsomal enzyme activities. The protective action of cysteamine was likewise assessed in the light
Metabolic activation of thioacetamide (CH3CSNH2) to a toxic metabolite which is responsible for its hepatotoxicity and/or its carcinogenicity has been proposed by a number of investigators. In this investigation thioacetamide and one of its metabolites, thioacetamide sulfine (CH3CSONH2), have been
The Cordyceps species has been a good source of compounds with anticancer and anti-inflammatory activities. Recently, we reported a novel compound (4-isopropyl-2,6-bis(1-phenylethyl)phenol, KTH-13) with anticancer activity isolated from Cordyceps bassiana and created several derivatives to increase
Fourteen substituted 4-anilinoquinazolines have been tested for cytotoxic effect and structure activity relationships. The most active derivatives were substituted by chlorine or bromine group in the aromatic ring, in the pyrimidine ring by morpholine group and in the aniline skeleton by nitro group
The p38 mitogen-activated protein (MAP) kinases are a family of serine/threonine protein kinases that play important roles in cellular responses to inflammation and external stress. Inhibitors of the p38 MAP kinase have shown promise for potential treatment of inflammatory disorders such as
Oral administration of diethyldithiocarbamate (DTC) and carbon disulfide (CS2) protected mice against CHCl3-induced kidney injury, as evidenced by normalization of delayed plasma phenolsulfonphthalein clearance, suppression of increased kidney calcium content and prevention of renal tubular
BACKGROUND
The aim of this study was to show the clinical and pathological characteristics of anti-centromere-antibody (ACA)-seropositive Sjögren's syndrome (SS) in two anti-human T-cell leukemia virus type I (HTLV-I)-seropositive patients.
METHODS
One patient was an HTLV-I carrier whereas the other
Callose is a β-l,3-glucan with diverse roles in the viral pathogenesis of plants. It is widely believed that the deposition of callose and hypersensitive reaction (HR) are critical defence responses of host plants against viral infection. However, the sequence of these two events and their
OBJECTIVE
To evaluate histologically the integration process of cellulose gel produced by Zoogloea sp when implanted into rabbits' eviscerated eyes.
METHODS
This experimental study employed 36 eyes of 18 rabbits subjected to evisceration of their right eyes. The sclerocorneal bag was sutured and
The protective effects of saponins isolated from the root of Platycodon grandiflorum (Changkil saponins: CKS) against alcoholic steatosis in liver injury induced by acute ethanol administration were investigated. Pretreatment with CKS prior to ethanol administration significantly prevented the
OBJECTIVE
To evaluate the repair process in rats with experimentally induced arterial hypertension. This study aimed to evaluate lesions in the ventricular myocardium and the repair process during experimental hypertension induced by systemic blockage of nitric oxide using N-omega-nitro-L-arginine
Solanum alatum Moench. has been shown to have a protective effect against carbon tetrachloride (CCl4)-induced liver injury. Solanum alatum treatment (100 mg/kg, p.o.) decreased the elevation of serum alanine aminotransferase (ALT; GPT) and aspartate aminotransferase (AST; GOT) induced by
Administration of anesthetic doses of halothane to hyperthyroid male rats results in the development of hepatic necrosis. The severity of the hepatic lesion was dependent on the dose of triiodothyronine (T3) and the length of time it was administered. Pretreatment of rats with iodinated metabolites
