Spatio-temporal course of macrophage-like cell accumulation after experimental embolic stroke depending on treatment with tissue plasminogen activator and its combination with hyperbaric oxygenation.

What Researchers Did

Researchers investigated the spatio-temporal accumulation of macrophage-like cells and glial reactions in rats after experimental thromboembolic stroke, assessing the effects of tissue plasminogen activator (tPA) alone and in combination with hyperbaric oxygen (HBO).

What They Found

Macrophage-like cell accumulation distinctly increased from 24 hours to 7 days post-ischaemia in all groups. The combination of tPA and HBO tended to decrease macrophage-like cell accumulation at day 14 and 28, with a trend towards an association between increased accumulation and pronounced reduction of the neurological deficit.

Canadian Relevance

This study has no direct Canadian connection as it was conducted internationally using an animal model.

Study Limitations

The findings are based on an experimental animal model, limiting direct generalizability to human patients.
