Results and discussion

Details on results:
Carrageenan injected into the plantar tissue of the hind paw of the test animals produces an edematous condition with simulates, in parts, the inflammatory process found in human arthritis. The subsequent oral application of 200 mg/kg 4-Chlorobenzonitrile led to an 30% reduction of the edema.The LD50 was reported to be > 300 mg/kg bw

Applicant's summary and conclusion

Conclusions:
Oral application of 200 mg/kg bw 4-Chlorobenzonitrile has an anti-inflammatory effect in the carrageenan-induced pedal edema assay in rat. An LD50 of > 300 mg/kg bw was reported.
