The fingerprint location from the capsaicin spectrum The Raman the spectra of patch-treated and are shown in Figure was compared withcorrelation maps of the patchesuntreated human skin. 8. The Raman correlation maps demonstrated the presence of capsaicin in different regions of human The Raman correlation maps of the patches are shown in Figure 8. The Raman skin. In correlation with the IVRT and IVPT benefits, additional different regions of was observed correlation maps demonstrated the presence of capsaicin ineffective penetration human together with the two.three mg/g patch than with all the 1 mg/g a single.additional efficient penetration was dermis skin. In correlation together with the IVRT and IVPT final results, Capsaicin was detected within the noticed and epidermis. together with the two.3 mg/g patch than together with the 1 mg/g 1. Capsaicin was detected inside the dermisand epidermis. 2.two. Final results of In Vivo Experiments 2.two.1. The Capsaicin-Containing Dermal Patch Alleviates Heat HyperalgesiaIn experiments with patch application instantly right after the incision of hind paws, surgical intervention decreased the thermal pain threshold in animals treated with manage patches compared to the baseline worth, at the same time as to the contralateral intact paw.Anti-Mouse CD209b Antibody In stock The thermal pain threshold from the operated paws in capsaicin-treated rats was nonetheless reduced than the respective baseline worth, nevertheless it was considerably bigger than the threshold from the operated legs of bandage-treated control animals. The thermal sensitivity of the intact paws of capsaicin-treated rats did not differ in the baseline value taken before surgery. Adhesive bandages had no effect around the thermal discomfort threshold of hind paws (Figure 9). In experiments with delayed patch application, the surgical incision of paws significantly reduced the discomfort threshold when compared with contralateral intact paws and respective baseline values. Manage patches without having capsaicin failed to improve this condition. Capsaicin-releasing patches elevated the thermal discomfort threshold compared to the handle patch. The mitigated threshold was nonetheless reduce than the baseline with the paw. Neither manage nor capsaicin-containing patches changed the hyperalgesia of intact paws (Figure 10).FMK Cancer Pharmaceuticals 2022, 15, x FOR PEER REVIEWPharmaceuticals 2022, 15,7 of7 ofPharmaceuticals 2022, 15, x FOR PEER Review Figure 8.PMID:23514335 Raman correlation maps for the distribution of capsaicin in human skin after therapy with patches.
