Effects of melatonin on hepatic glutathione-peroxidase (GSH-Px) and glutathione-reductase (GSH-reductase) activities were studied in Sprague-Dawley (SD) rats administered i.p. (10 mg/kg body weight) with melatonin during 15 days. The activity of cytosolic GSH-reductase in the liver was not changed by melatonin. However, melatonin injection increased significantly the activity of liver cytosolic GSH-Px activity compared with those in saline-treated rats. At the same time, plasma GSH-Px was also...

It is becoming increasingly clear that the inflammatory reaction can be ascribed to a complex array of mediators generated and released from activated phagocytes. In this study, the effect of PAF on interleukin-1(IL-1) activity by rat alveolar macrophages(AM) was examined using thymocyte proliferation assay in the supernate of sample obtained after 24 hr culture. When AM were cultured with PAF alone, no change in IL-1 activity was observed. However, the combined addition of PAF and muramyl...

of northern blot and reverse transcriptase-polymerase chain reaction (RT-PCR). Hemorrhage produced a profound hypotension with tachycardia, but blood pressure and heart rate recovered close to the basal level at 7 h. Plasma and renal renin levels were significantly increased at 7 h. Hemorrhage induced rapid upregulation of gene expression of both AT1A and AT1B receptor subtypes in the brainstem and hypothalamus, downregulation of them in the adrenal gland and liver. However, renin mRNA level...

We studied the effects of ginseng protopanaxadiol (PD) and protopanaxatriol (PT) saponins on the analgesia using several pain tests such as writhing, formalin, and tail-flick test. Using mouse, pretreatment of PD or PT saponins (i.p.) induced inhibition of abdominal constrictions caused by 0.9% acetic acid administration(i.p.). The AD50 was around 27 (17-43) mg/kg for PD and 13.5 (3-61) mg/kg for PT saponins in writhing test. Both PD and PT saponins also showed the inhibition of bitings and...

their metabolites. Synaptosomes were prepared from the rat forebrains and assays of catecholamines and metabolites were made using HPLC with an electrochemical detector. Lithium of 1mM decreased the extrasynaptosomal concentrations of NE from the control group of 3.07⁑1.19 to the treated group of 0.00⁑0.00 (ng/ml of synaptosomal suspension) but not that of DHPG. It can be suggested that lithium increases synaptosomal uptake of NE. Increased intraneuronal uptake of NE would decrease...

The N-methyl-D-aspartate (NMDA) receptor-mediated glutamatergic neurotransmission is involved in synaptic plasticity, developmental processes, learning and memory and many neuropathological disorders including age-related diseases. In the present study, regulation of the NMDA receptor properties by various ligands was investigated using [3H]MK-801 binding studies in the synaptic membranes of young and aged rat forebrains. The binding in the presence of glutamate and glycine increased...

I receptor (AT1), TGF-Ղ1, and fibronectin gene expression in rats with unilateral ureteral obstruction (UUO). We also investigated the change of AT1 density during UUO. Reverse transcription-polymerase chain reaction (RT-PCR) technique and receptor binding assay were used to detect mRNA expression and receptor density, respectively. At one day after UUO, renin mRNA level of the obstructed kidneys was decreased transiently and then subsequently increased to the level of sham kidneys. In the...

streptozotocin (STZ) treatment (55 mg/kg, i.p.), rats were randomly divided into LPS-treated (1.6 mg/kg, i.p.) and control rats. At 6 hours after LPS treatment, the rats were killed and the kidney was removed from each rat. Northern blot and reverse transcription-polymerase chain reaction (RT-PCR) techniques were used to detect mRNA expression. STZ treatment markedly attenuated body weight gain and significantly increased blood glucose level. Renal renin content (RRC) was significantly decreased...

Cis-dichlorodiammine platinum II (Cisplatin), an effective chemotherapeutic agent, induces acute renal failure by unknown mechanisms. To investigate direct toxic effects of cisplatin on the renal proximal tubular transport system, LLC-PK1 cell line was selected as a cell model and the sugar transport activity was evaluated during a course of cisplatin treatment. Cells grown to confluence were treated with cisplatin for 60 min, washed, and then incubated for up to 5 days. At appropriate...

Carbamazepine (CBZ), an anticonvulsant, has beeen reported to displace ligands at adenosine receptors. Several studies have demonstrated that as far as A2 adenosine receptors is concerned, CBZ acts as an antagonist. However, the situation with regard to A1 receptors is less straightforward. In this study, we describe the effects of one-week CBZ treatment (25 mg/kg/day) on cerebrocortical A1 adenosine receptors. A1 adenosine receptor bindings as determined by using [3H]DPCPX was not...
