Ulcerogenic potential of the tested compounds 4, 9, 12, 13, 18, diclofenac and celecoxib in mice^*.

Compound no.	Average number of ulcers	Mean sum of lengths of elongated ulcer (mm ± SEM)
Control	0.0	0.0
Celecoxib	5	5.8 ± 0.77
Diclofenac	10	7.6 ± 0.89
4	6	4.7 ± 0.54
9	4	1.7 ± 0.21
12	5	2.4 ± 0.13
13	5	2.1 ± 0.23
18	2	0.9 ± 0.08

*Significantly less than the celecoxib and diclofenac sodium treated group using unpaired. Student’s t-test p < 0.05.
