Effect of digoxin, sodium valproate, and celecoxib on the cerebral cyclooxygenase pathway and neuron-specific enolase under the pentylenetetrazole-induced kindling in mice.

Neuroinflammation plays an important role in the pathogenesis of epilepsy, so it is necessary to clarify the influence of standard antiepileptic drugs as well as adjuvant agents (e.g., cardiac glycoside digoxin, which previously showed a clear anticonvulsant potential) on cyclooxygenase pathway and neuron-specific enolase under the conditions of chronic epileptogenesis.

Effect of Oligopeptides-Homologues of the Fragment of ACTH on Morphogenetic Markers of Stress in the Adrenal Glands on the Model of Acute Cold Injury in Rats.

Objectives: Aim of the current study was to evaluate the stress-protective effect of oligopeptides-homologues of the adrenocorticotropic hormone (ACTH) fragment 15-18 on morphogenetic signs of stress reaction of the adrenal glands under acute cold exposure (CE) in rats.

Materials And Methods: The acute cold stress was reproduced by placing random-bred male rats in a freezer at a temperature of -18°C for 2 hours. The peptides-homologous of ACTH acetyl-(D-Lys)-Lys-Arg-Arg-amide (KK-1) and acetyl-(D-Lys)-Lys-(D-Arg)-Arg-amide (KK-5) and the reference medicine (Sema) were administered intranasally in a dose of 20 mg/kg 30 minutes before and after CE.

Promising anticonvulsant N-[(2,4-dichlorophenyl) methyl]-2-(2,4-dioxo-1H-quinazolin-3-yl) acetamide: dose-dependent study and evaluation of anticonvulsant action spectrum in vivo and in silico.

The anticonvulsant spectrum of the original promising anticonvulsant N-[(2,4-dichlorophenyl) methyl]-2-(2,4-dioxo-1H-quinazolin-3-yl) acetamide was studied. The compound had a pronounced anticonvulsant effect, significantly reducing the mortality of mice in models of seizures induced by pentylenetetrazole, picrotoxin, strychnine, and caffeine. In the thiosemicarbazideinduced seizure model, the test compound did not reduce mortality.
