sentence: The intraperitoneal administration of oltipraz did not have any significant effects on nociception in either the ipsilateral paw of the sham-operated mice ( Figure 1 ) or the contralateral paw of the CCI-injured or sham-operated animals.In summary , these results indicate that the repeated intraperitoneal administration of oltipraz inhibited mechanical allodynia , thermal hyperalgesia , and thermal allodynia induced by CCI in the mice.Treatment with oltipraz also inhibited depressive-like behavior associated with neuropathic pain .
