Background Patients with Sjögren's syndrome (SS) typically present clinically with xerostomia (dry mouth) because of progressive damage to the exocrine glands. We developed a new, low-dose pilocarpine/sodium alginate (LPA) solution with pilocarpine hydrochloride to inhibit systemic adverse effects by administering via the oral mucosa. The purpose of this study was to assess its stability, safet...

UNLABELLED Selective neuronal loss following status epilepticus (SE) was first described just under 100 years ago. The acute pathology following SE was shown to be 'ischemic cell change' and was assumed to arise through hypoxia/ischemia. Recently, erythropoietin (Epo) has been shown to have potent anti-apoptosis activity in central nervous system neurons in animal models of ischaemic injury. ...

A variety of observations suggest that decreasing glycolysis and increasing levels of reduced glutathione, generated by metabolism of glucose through the pentose phosphate pathway, would have an anticonvulsant effect. Because fructose-1,6-bisphosphate (F1,6BP) shifts the metabolism of glucose from glycolysis to the pentose phosphate pathway, it was hypothesized to have anticonvulsant activity. ...

BACKGROUND AND OBJECTIVES In patients with epilepsy, a common comorbidity diagnosed is depression. Temporal lobe epilepsy or post status epilepticus (SE) animal model establish and validate the co morbidity and common pathogenesis of depression and epilepsy. Elevation in serotonin concentration gives an inhibitory response to epileptic discharge and stabilizes the depressed mood disorder. Piper...

Pilocarpine-induced rat epilepsy model is an established animal model that mimics medial temporal lobe epilepsy in humans. The purpose of this study was to investigate neuroimaging abnormalities in various stages of epileptogenesis and to correlate them with seizure severity in pilocarpine-induced rat epilepsy model. Fifty male Sprague-Dawley rats were subject to continuous video and electroenc...

In previous experiments it has been demonstrated that the synthesis of BDNF (brain-derived neurotrophic factor) and NGF in neurons of the hippocampus is regulated by neuronal activity. The glutamate system is predominantly responsible for upregulation and the GABAergic system for downregulation both in vitro and in vivo (Zafra et al., 1990, 1991). The aim of the present study is to examine the ...

Nimodipine has been shown to have an inhibitory action on seizures and brain damage in rodents. However, the pharmaceutical applicability of this drug is limited by its low solubility in gastrointestinal fluids and high first-pass effect in the liver, which leads to low bioavailability. These difficulties can be overcome through the use of liposomes. The aim of the present study is to evaluate ...

OBJECTIVES To determine the effects of H-7 on (1) iris and ciliary muscles (CMs) in living monkeys; (2) isolated monkey CM strips; (3) actomyosin contractility in cultured Swiss 3T3 cells. METHODS (1) Pupillary diameter (calipers) and accommodation (refractometer) in living monkeys were measured after topical, intracameral, or intravitreal administration of H-7 followed by systemic pilocarpin...

We have generated an experimental 'double-hit' model of chronic epilepsy to recapitulate the co-existence of abnormal cortical structure and frequently recurrent seizures as observed in human focal cortical dysplasia. We induced cortical malformations by exposing rats prenatally to methylazoxymethanol acetate and triggered status epilepticus and recurrent seizures in adult methylazoxymethanol a...

The effect of pilocarpine on visual acuity and on the dimensions of the cornea, anterior chamber, and lens were studied in two groups of subjects. Significant changes in ocular tension, corneal curvature, anterior chamber depth, and lens anterior radius were found in a group of 55 glaucomatous eyes as a result of pilocarpine treatment, but there was no change in corneal thickness. Out of 102 gl...
