Ubiquitin Expression in the Lumbar Spinal Cord Motoneurons of Postnatal Mice-- an Immunohistochemical Study

Description: Maturation of spinal motoneurons in rodents is characterized by a period of cell loss in the embryo, but researchers have claimed that some cell death occurs postnatally. This form of cell death is called apoptosis and involves active participation of the cell. Apoptotic cells have certain recognizable morphological and molecular features. I have used a monoclonal antibody against ubiquitin, (a putative marker of apoptotic cells), to do immunochemistry on mouse spinal cords at various postnatal… more

In Vitro Studies of Nuclear Changes in Mammalian CNS Neurons Subjected to Rapid Acceleration Impact Injury

Description: An in vitro model of Rapid Acceleration Impact (RAI) Injury was used to study the effects of multiple impact (220 g/impact, 3-5 sec intervals) trauma on cultures of murine CNS cells. Investigations with spinal cord cultures showed that 1) multiple impacts delivered tangential to the plane of cell growth caused neuronal death (12% after 3 impacts to 46% after 10 impacts); 2) multiple impacts delivered normal to the plane of cell growth were much less effective (8% dead after 10 impacts); 3) most… more

Effects of 5-hydroxytryptamine on Mouse Lumbar Motor Activity During Postnatal Development

Description: The lumbar motor activity in isolated spinal cords of 72 postnatal Balb/C mice aged 2, 5, 10 and 21 days (PN2-21) was electroneurographically recorded (ENG) via bilateral ventral roots following treatment with three different concentrations (25, 100 and 200 pM) of the neurotransmitter, 5-hydroxytryptamine (5-HT), i.e., serotonin, to determine its effects on spinal pattern generation.
