Cost analysis of therapy for patients with multiple sclerosis (MS) in Poland.

Multiple sclerosis (MS) is a neurological disease of the central nervous system in which dissipated demyelination lesions develop. The currently available pharmacotherapy and rehabilitation for this disease aims to preserve the patients' physical abilities and prevent disease progression and nervous system damage. The study evaluated the direct and indirect costs associated with two different treatment regimens for multiple sclerosis diagnosed patients by comparing two groups of 60 subjects (Group A--patients receiving continuous interferon therapy (Betaferon) and steroids during relapses, and Group B--patients receiving steroid-only (Solu-Medrol, Metypred) treatment).

[Folic acid: new indications for an old well-known drug].

Unlabelled: This review deals with the well known drug--folic acid, for which new indications have been discovered in recent years. The drug was used for 50 years in anemia megaloblastia, other anemias with bone marrow hypofunction, in leucopenia and granulocytopenia, in celiac disease and sprue and folic acid deficit during oral anticonceptive drug use. From recent investigations follows that there are strong indications for the use of folic acid in a periconceptual period and during pregnancy (at least 600 micrograms per day) and during lactation--to prevent neural tube defects.

MSRV pol sequence copy number as a potential marker of multiple sclerosis.

Multiple sclerosis (MS) is a neurological disease in which demyelination in the brain and spinal cord is observed. The causal influence of bacterial/viral infections and genetic/immune factors in the etiology of multiple sclerosis is suggested. Multiple sclerosis-related retrovirus (MSRV) is one of the potential agents, which can lead to development of the disease.

Limited pattern of TCR delta chain gene rearrangement on the RNA level in multiple sclerosis.

Susceptibility to multiple sclerosis (MS) is most likely affected by a number of genes, including HLA and T-cell receptor (TCR) genes. T cells expressing gamma/delta receptors seem to contribute to autoagression in MS, as evidenced by their localization in the MS plaques in the brain. The aim of this study was to analyse the TCRdelta chain gene rearrangement at the RNA (cDNA) level and compare to the DNA pattern rearrangement.

Role of neuropeptides in antidepressant and memory improving effects of venlafaxine.

The aim of this study has been to investigate the effects of vasopressin and oxytocin on antidepressive and memory improving effects of venlafaxine. Male Wistar rats weighing 180-200 g were used in the study. Venlafaxine (20 mg/kg) was administered po 30 min before the test once, and for 7 and 14 days in the chronic experiments.
