In this paper, we implement a real-time surveillance system for image object tracking using PTZ (Pan-Tilt-Zoom) cameras. For this, we use the mean shift tracking algorithm based on the color image distribution of detected object. Mean shift algorithm is efficient for real-time tracking because of its fast and stable performance. In this system, OpenCV environment is used for image processing an...
An integrated system for automatic detection, handover and tracking of an intruder using one fixed camera and one Pan/Tilt/Zoom(PTZ) camera is presented. This system includes automatic detection using an overhead static camera of an intruder who walks into a crowded secure area, intruder handover from the static to the nearest PTZ camera, and tracking using the PTZ camera. The intruder is detec...
The role of opioid receptor and voltage dependent calcium channels on the kindling induced by the convulsant pentylenetetrazole (PTZ) were investigated in the rats. Experiment involved 24 rats which were divided into four groups. Kindling was established with PTZ in subconvulsive dose (37.5 mg/kg i.p.) every 48 h and effects were observed within 20 min using five-point scoring system. All anima...
Cysteinyl leukotrienes (CysLTs) have been implicated in seizures and kindling; however, the effect of CysLT receptor antagonists on seizure frequency in kindled animals and changes in CysLT receptor expression after pentylenetetrazol (PTZ)-induced kindling have not been investigated. In this study, we evaluated whether the CysLT1 inverse agonist montelukast, and a classical anticonvulsant, phen...
The present study aimed at establishing two models of experimental seizures by combination treatment with subconvulsive doses of PTZ and kainic acid in adult male mice and evaluating the modulatory role of cerebroselective dihydropyridine calcium channel blocker, nimodipine. The CD50 +/- SEM value for PTZ was found to be 20.00 +/- 0.92 mg/kg, ip in kainic acid (administered at per se subconvuls...
This study examines the effect of acute administration of caffeine sodium benzoate (CAF) on the anticonvulsant action of four conventional antiepileptic drugs (AEDs: clonazepam - CZP, ethosuximide - ETS, phenobarbital - PB and valproate - VPA) against pentetrazole (PTZ)-induced clonic seizures in mice. The results indicate that CAF at a dose of 92.4 mg/kg significantly reduced the threshold for...
Objectives: This study aimed to investigate the effects of prenatal stress (PS) on hippocampus early acute pentylenetetrazole (PTZ)-kindled offspring in adolescence. Recognition memory, morphological changes and synaptophysin levels were evaluated. Methods: Restraint was induced a group pregnant dams non-stressed (NA) remained undisturbed. Next, male female divided as 1. PS-PTZ, 2. PS -control,...
Neuroactive steroids are naturally occurring or synthetically derived compounds many of which have anticonvulsant, anesthetic, anxiolytic, analgesic or hypnotic properties. The major site of neuronal activity appears to be with a specific steroid-sensitive site on the gamma-aminobutyric acidA receptor/chloride ionophore complex. Ganaxolone (3 alpha-hydroxy-3 beta-methyl-5 alpha-pregnan-20-one) ...
هر موش صحرایی نر ویستار mg/kg 45 ptz را بصورت داخل صفاقی تا 13 تزریق دریافت کرد. از لیدوکائین به منظور غیرفعال سازی lh استفاده شد و رفتارهای تشنجی به عنوان شاخص کیندلینگ هیپوکمپ ارزیابی شدند. محتوای گلوتامات با کیت سنجش گلوتامات اندازه گیری شد. مغزهای فیکس شده برش داده شدند و با کرزیل ویوله رنگ آمیزی شدند تا تغییرات بافتی مشاهده شود. تزریقات ptz باعث کیندلینگ و کاهش محتوای گلوتامات می شود در حا...
Magnesium sulfate (MgSO₄) has been used to prevent seizures in eclampsia. This study examined the central effects of MgSO₄ on different types of pentylenetetrazole (PTZ)-induced seizures. Male Wistar rats were submitted to intracerebroventricular (ICV) administration of MgSO₄ at different doses followed by intraperitoneal administration of PTZ. The latency to the onset of the first seizure indu...
