OBJECTIVES To explore the effect of edaravone (ED) on apoptosis of hippocampus neurons in seizures rats induced by pentylenetetrazole (PTZ). MATERIALS AND METHODS Forty-eight adult Wistar rats were randomly divided into normal control (NC) group, PTZ group, and ED group. A dose of PTZ [35 mg/(kg·day)] was intraperitoneally (i.p.) injected into the rats of PTZ group and ED group until the kind...

The aim of the present study was to research the role of nitric oxide (NO) as a mediator of alpha (α)-asarone effect at the pentylenetetrazol (PTZ)-induced epileptiform discharge in rat. α-Asarone that was injected intraperitoneally twenty minutes before PTZ injection suppressed the clonic discharge effectively and the significant actions lasted for 30 min with no change of clonic amplitude. Ad...

Flgure 4. Calibration curve for PTZ and PANA in TMP. Data were collected for solutions prepared by addition of 1.000 g of antioxidant/TMP oil mixture to 5.00 mL of acetonitrile. A 10-pm (diameter) platinum ultramicroelectrode in cell configuration 3 was used. Scan rate was 25 mV/s. PTZ data points, open circles; PANA data points, filled circles. Slope/intercept information (units as given on fi...

Mechanism of photo-induced electron transfer and the subsequent hole transfer in DNA has been studied extensively, but so far we are not aware of any reliable report of the observation of the long-distance hole-transfer process. In this article, we demonstrate the results of direct observation for the long-distance hole transfer in double-helical DNA over 100 A with time-resolved transient abso...

Oral administration of carbaryl to adult male albino rats produced a dose dependent increase in the steady state level of 5-hydroxytryptamine (5-HT) at 1.00 h in pons-medulla (PM). 5-Hydroxyindole acetic acid (5-HIAA) concentration was significantly elevated only in response to a higher dose of this pesticide under similar conditions. A time course study with carbaryl and pentylenetetrazol (PTZ...

advantages as an alternative dosage form (i) avoiding firstpass metabolism, (ii) easy discontinuation of administration, and (iii) reduced side effects; however, the stratum corneum, which is the outermost layer of skin, provides a primary barrier to transdermal drug delivery. Pentazocine (PTZ), a relatively short-acting narcotic-antagonist analgesic, is used clinically for the relief of cancer...

Stress is the body’s reaction to any change that requires adaptive responses. In various organisms, stress a seizure-related comorbidity. Despite exposure stressors eliciting aversive behaviors in zebrafish, there are no data showing whether potentiates epileptic seizures this species. Here, we investigated previous an intense acute stressor positively modulates susceptibility pentylenetetrazol...

The phenotype pantoprazole-C breath test (Ptz-BT) was used to evaluate the extent of phenoconversion of CYP2C19 enzyme activity caused by commonly prescribed proton pump inhibitors (PPI) omeprazole and esomprazole. The Ptz-BT was administered to 26 healthy volunteers and 8 stable cardiovascular patients twice at baseline and after 28 days of PPI therapy to evaluate reproducibility of the Ptz-BT...

The asymptomatic properties and high treatment resistance of ovarian cancer result in poor treatment outcomes and high mortality rates. Although the fundamental chemotherapy provides promising anticancer activities, it is associated with severe side effects. The derivative of phenothiazine, namely, 10H-3,6-diazaphenothiazine (PTZ), was synthesized and reported with ideal anticancer effects in a...

Lafora disease is a rare form of inherited progressive myoclonus epilepsy caused by mutations in the EPM2A gene encoding laforin, or in the EPM2B gene, which encodes malin. It is characterized by the presence of polyglucosan inclusion bodies (Lafora bodies) in brain and other tissues. Genetically engineered mice lacking expression of either the laforin (Epm2a(-/-) ) or malin (Epm2b(-/-) ) genes...
