Hyperbaric oxygen treatment time for cyclophosphamide induced cystitis in rats
1Department of Medical Histology and Embryology, Gulhane Military Medical Academy, 06018 Etlik, Ankara, Turkey.
Summary
Hyperbaric oxygen therapy (HBO2) does not prevent cyclophosphamide-induced cystitis. However, HBO2 treatment after cyclophosphamide administration helps repair bladder damage and reduces hemorrhagic cystitis severity in rats.
Area of Science:
- Urology
- Experimental Medicine
- Pharmacology
Background:
- Cyclophosphamide (CYP) is a chemotherapeutic agent known to induce hemorrhagic cystitis.
- Hyperbaric oxygenation (HBO2) therapy is explored for its potential therapeutic effects in various conditions.
Purpose of the Study:
- To evaluate the prophylactic potential of HBO2 therapy for CYP-induced cystitis.
- To determine the optimal timing for HBO2 administration in mitigating CYP-induced bladder damage.
Main Methods:
- Forty male Sprague-Dawley rats were used, divided into five groups.
- Four groups received a single dose of CYP (100 mg/kg) intraperitoneally.
- Different HBO2 treatment timings (before, during, and after CYP administration) were tested.
Main Results:
- CYP injection induced severe cystitis in rats.
- Prophylactic HBO2 treatment did not prevent the development of severe cystitis.
- HBO2 treatment administered after CYP injection attenuated the severity of hemorrhagic cystitis.
Conclusions:
- HBO2 therapy demonstrates a beneficial effect in repairing and healing bladder damage post-CYP induction.
- HBO2 does not prevent CYP-induced hemorrhagic cystitis but mitigates its severity when applied therapeutically.
