The clinical use of paclitaxel (PCL) may cause nephrotoxicity. Antioxidants have shown potential benefits in some disease conditions. This study examined the protective abilities of coenzyme Q10 (CoQ10) and resveratrol (RSV) against PCL-induced nephrotoxicity in albino rats. Adult male albino rats (n=45) were divided into 9 groups of n=5. The rats were supplemented orally with CoQ10 (20mg/kg), RSV (20mg/kg) and CoQ10+RSV (ip) daily for 5 days respectively before the administration a dose of PCL (20mg/kg) i.p on day 5. The rats were euthanized; blood samples were collected and assessed for serum biochemical markers. Kidneys were assessed for melondialdehyde, antioxidants (superoxide dismutase, glutathione, glutathione peroxidase and catalase) and histology. Body and kidney weights were normal (p>0.05) in PCL administered rats when compared to control. Serum total protein, albumin, potassium, chloride, sodium, bicarbonate and kidney malondialdehyde levels were significantly (p

The manifestation of acute hepatotoxicity caused by 5-fluorouracil could be characterized by asymptomatic elevations of liver enzymes, hepatic steatosis and fuminant hepatitis. Natural antioxidants have potential as excellent treatment strategy against diseases and drug-induced toxicities. This study assessed the potential of resveratrol (RSV) to abrogate the hepatotoxic effect of 5-FU in rats. Forty adult male albino rats (240g± 20g) were randomized and orally supplemented with RSV (10, 20 and 40 mg/kg/day) prior to the administration of 5-FU (20mg/kg/day) intraperitoneally for 5 days. On day 6, after weighing, the rats were anesthetized, blood samples were collected and centrifuged and sera obtianed. Liver tissues were harvested and weighed. Sera and liver samples were evaluated for biochemical parameters. Liver tissues were assessed for histology. Body weight was significantly (p

Background and aims: Zea mays L. (Poaceae) husk extract is used traditionally in Ibibio traditional medicine for the treatment of various diseases such as malaria, pains, inflammatory diseases and central nervous system disorders.Methods: The husk extract (187-748 mg/kg) was evaluated for antidepressant activity in mice using open field, force swimming and tail suspension tests. Determination of median lethal dose (LD50) and phytochemical screening of the husk extract were also carried out using standard methods.Results: The husk extract increased significantly the line crossing, walling and rearing activities of mice in open field test (P

Psychotic depression is an identified subtype of major depression that has many features of a distinct psychiatric disorder. Recent studies support previous findings that psychotic depression is associated with a less favorable course of illness. Moreover, the presence of a single psychotic symptom appears to predict decreased responsiveness to antidepressant monotherapy. Recent studies also support biological differences between psychotic and non-psychotic depression. Previous findings of greater HPA axis dysregulation are supported by evidence of diminished cortisol suppression with the mineralocorticoid antagonist fludrocortisone in psychotic depression. Moreover, a functional neuroimaging study demonstrated greater activation in parahippocampal and tempoparietal regions in psychotic depression during a memory task. In support of several previous treatment studies, a recent meta-analysis of studies that compared an antidepressant-antipsychotic combination to antidepressants or antipsychotics alone found a therapeutic advantage with the combined treatment over monotherapy. A recent clinical trial suggests that mifepristone, a glucocorticoid antagonist, may be an effective adjunctive treatment for psychotic depression. [ABSTRACT FROM AUTHOR]

The aim of the present work is a preliminary set of groups that make up the Crust Lateritico Niqueliferas Cobaltiferas of Punta Gorda Reservoir in Cuba by neural networks applied to a sef of radioactive well logs according to a predetermined geolical classification . It also undertakes assesment of nickel content in each of the defined groups also implementing neural networks.
