Text

Objective: The objective of the study is comparative evaluation of some selected pharmaceutical agents administered by stereotactic cerebroventricular route after experimental brain edema in rats.

Method: Six groups of rats, i.e. five experimental and one control, in similar conditions are used in the study. Standard brain trauma is produced by the weight drop method. In therapy groups, 2 microliters of therapeutic agent is administered 6, 12, and 24 hours after neurotrauma by cerebroventricular stereotactic route. The rats are sacrificed after 48 hours and brain tissue is extracted without extra damage. Analyses of GSH, NO, MDA, TNF-alpha, and IL-1-beta are performed on traumatic left hemispheres.

Results: GSH levels in all therapy groups except for the glycerin group revealed a statistically significant increase compared to control group. MDA and NO levels had different ratios of decrease, which showed a trend but without statistical significance. IL-1-beta showed a significant decrease in therapy groups, but TNF-alpha analysis revealed no difference between control and treatment groups.

Conclusions: Study results showed that brain edema and secondary brain injury due to oxidative stress might be decreased by the use of some selected pharmaceutical agents via cerebroventricular route on experimental basis. Additional studies with albumin, mannitol, hypertonic NaCl and dextran may be promising.
