Kidney damage is markedly accelerated by high-salt (HS) intake in stroke-prone spontaneously hypertensive rats (SHRSP). Epoxyeicosatrienoic acids (EETs) are epoxygenase products of arachidonic acid which possess vasodepressor, natriuretic, and anti-inflammatory activities. We examined whether up-regulation (clofibrate) or inhibition [N-methylsulfonyl-6-(2-propargyloxyphenyl)hexanamide (MS-PPOH)...

Myocardial infarction (MI) has been associated with an inflammatory response and a rise in TNF-α, interleukin (IL)-1β, and IL-6. Peroxisome proliferator-activated receptors (PPARs) promote a decreased expression of inflammatory molecules. We aimed to study whether PPAR stimulation by clofibrate decreases inflammation and reduces infarct size in rats with MI. Male Wistar rats were randomized int...

Clofibrate is a glucuronosyl transferase inducer that has been proposed to increase the elimination of bilirubin in neonates with hyperbilirubinemia. This study was conducted to determine the therapeutic effect of clofibrate in term neonates with non-hemolytic jaundice. This study was conducted on 52 newborns with pathologic unconjugated jaundice in Qazvin children hospital. Newborns divided ra...

The dose-dependence of di(2-ethylhexyl)phthalate (DEHP) hepatocarcinogenicity was investigated in male F344 rats which were initially injected with diethylnitrosamine (200 mg/kg, i.p.) and subjected to partial hepatectomy at week 3. The animals were administered DEHP in the diet at concentrations of 30, 300, 3,000, or 12,000 ppm starting 2 weeks after the DEN injection for up to 46 weeks and ki...

1. Chlorpropamide, carbamazepine and clofibrate have an antidiuretic action in patients with neurohypophyseal diabetes insipidus which is qualitatively similar to that of antidiuretic hormone (ADH). 2. An additive antidiuretic effect is produced by combination of chlorpropamide and carbamazepine with small dosages of ADH. 3. After an immediate and transient antidiuresis, a single intravenous bo...

The subcellular localization of dihydroxyacetone phosphate acyltransferase (DHAPAT) activity in rat small intestine was investigated by Nycodenz-gradient centrifugation. We found that DHAPAT had a predominant peroxisomal distribution, with a separate enzyme activity located in the microsomal fraction, the same distribution as found in rat liver. The effect of feeding rats on a diet with 20% (w/...

Peroxisome proliferators such as the fibrates act via the peroxisome proliferator activated receptor (PPAR)-alpha as hypolipidemic agents. Many peroxisome proliferators are also nongenotoxic hepatic carcinogens and hepatotoxicants in rodents. We performed transcription profiling using cDNA microarrays on livers of rats treated for 5 days with 3 doses of the peroxisome proliferator clofibrate. A...

Intravascular coagulation (IVC) was evaluated in 19 patients with type II and 11 with type IV hyperlipoproteinemia before and after clofibrate therapy by measurements of soluble fibrin complexes (SFC) in plasma; fibrinolysis was estimated by quantitation of fibrin (ogen) degradation products in serum. Untreated type II and type IV patients had increased SFC (P less than 0.01). The former also h...

Icariin is effective in the treatment of hyperlipidemia. To understand the effect of icariin on lipid metabolism, effects of icariin on PPARα and its target genes were investigated. Mice were treated orally with icariin at doses of 0, 100, 200, and 400 mg/kg, or clofibrate (500 mg/kg) for five days. Liver total RNA was isolated and the expressions of PPARα and lipid metabolism genes were examin...
