Comparative StudyImproved behavioral outcomes after progesterone administration in aged male rats with traumatic brain injury.
Twenty-month-old male Fischer 344 rats with bilateral contusions of the frontal cortex (n=8/group) or sham operations received 16 mg/kg of progesterone or vehicle at 1 and 6 h post-injury, then once every 24 h for the next seven days, with tapering of the dose over the final two treatments. The rats' behavioral recovery was then evaluated on tests of locomotor activity and Morris water maze learning. ⋯ The progesterone-treated rats had better functional outcomes than vehicle-treated rats with similar cortical injuries. The neurosteroid treatment did not affect the size of the necrotic cavity.

Comparative StudyNeuroprotective effects of progesterone and allopregnanolone on long-term cognitive outcome after global cerebral ischemia.
To assess the longterm neuroprotective effects of progesterone (P₄) and allopregnanolone (ALLO) on functional and morphological parameters of the integrity of the hippocampus, after global cerebral ischemia. ⋯ Performance of P₄ or ALLO treated rats in learning and memory tests suggests that these steroids promoted neural conditions accounting for adequate functioning long after ischemia, in spite of the loss of hippocampal pyramidal neurons.

Longitudinal study of wind-up responses after graded spinal cord injuries in the adult rat.
The main objectives of this work were to evaluate the development of neuropathic pain after spinal cord injuries of different severities, and to assess changes in central excitability and plasticity by means of wind-up responses and withdrawal reflexes. ⋯ These results indicate that the graded-force spinal cord contusion model is suitable for studying central neuropathic pain, and for assessing changes in wind-up responses. Wind-up measurements can be used as a non-invasive technique to detect changes in central excitability after SCI of different severities.

Treatment with nerve grafts and aFGF attenuates allodynia caused by cervical root transection injuries.
Nerve root traction injuries induce spinal cord inflammation and lead to neuronal death within days. In the present study, we examined the inflammatory response one week after multiple cervical root transections. ⋯ This study demonstrated a correlation between an increased number of IL-1β-positive astrocytes and the development of allodynia. Our treatment significantly decreased IL-1β-positive astrocytes, thus preventing the occurrence of neuropathic pain following multiple cervical root injuries.

EditorialInstitutional profile: integrated center for research and treatment of vertigo, balance and ocular motor disorders.
In 2009 the German BMBF (German Ministry of Education and Research) established an Integrated Center for Research and Treatment (IFB(LMU)) of Vertigo, Balance and Ocular Motor Disorders in Munich. After the 10-year period of funding by the BMBF, it is envisioned that the (IFB(LMU)) will continue over the long term with the joint support of the University Hospital, the Medical Faculty, and the Bavarian State. Vertigo is one of the most common complaints in medicine. ⋯ This should promote the principles of efficiency and self-reliance; to supplement the existing excellence with up to eight groups of young scientists and up to eight professorships (tenure track). This should also be seen as an incentive that will attract the best young scientists; to incorporate (IFB(LMU)) competence into the existing medical and biological graduate schools. The (IFB(LMU)) is a unique center - worldwide.
