Fig. 5. Expression of NF-kB protein in gingiva using immunohistochemical methods. *Data are presented as mean ± standard deviation. For each treatment, testing was carried out in four repetitions. * NC: Negative control, PC: Positive control (Bacterial induced rats), BC: Base cream control (1 × oral BC applied), CC: Comparative control (1× kenalog cream applied), SWC1: Sappan cream 1 (PC + 1 times cream applied), SWC2: Sappan cream 2 (PC + 2 times cream applied). Different superscripts (a,b,c,d) mark significant differences among treatments based on Tukey HSD post hoc test (p < 0.05). The black arrows indicate the cell positive with NF-kB protein. SC: stratum corneum; SS: stratum spinosum; SB: stratum basalis.
