Abstract

Background: Stress that is induced by sleep deprivation can modulate the damage of periodontal tissue by elevating the levels of proinflammatory cytokines (i.e. IL-1β and TNF-α). The effects of sleep deprivation can be resolved with sleep recovery. Gingival crevicular fluid (GCF) is fluid in sulcular gingiva which acts as an oral biomarker for evaluating periodontal abnormalities. Purpose: The aim of this study was to determine the effect of various induction methods of sleep deprivation stress on cytokine levels in GCF of white male Wistar strain rats (Rattus novergicus). Methods: The study method was true experimental with a posttest-only control group design. Thirty male Wistar rats were randomly divided into five groups: paradoxical sleep deprivation (PSD), total sleep deprivation (TSD), partial sleep deprivation with sleep recovery for five days (PSD+SR), total sleep deprivation with sleep recovery for five days (TSD+SR) and a healthy control group. Data were analysed via one-way ANOVA to determine differences between groups. Result: The results showed the highest level of IL-1β and TNF-α was found in the PSD group. One-way ANOVA analysis showed significant differences (p<0,05) of IL-1β level between PSD and control groups, PSD and PSD+SR groups and PSD and TSD+SR groups; in contrast, the analysis of TNF-α levels showed significant differences (p<0,05) between PSD group to control group, PSD to PSD+SR group and TSD to TSD+SR group. Conclusions: There is an effect of various induction methods of sleep deprivation stress on proinflammatory cytokines (IL-1β and TNF-α).

Abstract

Background: Oral squamous cell carcinoma (OSCC) is an oral cancer with a low life expectancy, less than five years after diagnosis. The drug therapy often used for OSCC patients is cisplatin, but it is considered to cause tumour persistence, drug resistance, and high toxicity. Therefore, it is important to test the development of alternative drugs from natural ingredients. One potential ingredient is green chilli pepper (Capsicum frutescens L.). It contains capsaicin that functions as an anticancer agent by suppressing BCa tumorigenesis so that proliferation is inhibited, as well as increasing and preventing p53 antibody mutations that play a role in cancer cell apoptosis. Purpose: This study aimed to compare effectiveness using capsaicin nanoparticle gel from green chilli pepper extract levels of 1% and 3.3% to reduce OSCC nodules. Methods: This study used 20 Rattus norvegicus that were randomly divided into five groups; C- (rat without treatment), C+ (rat induced to 7,12-Dimethylbenz(a)anthracene (DMBA)), E1 (DMBA exposed and given cisplatin, E2 (rat induced to DMBA and capsaicin extract nanoparticle gel with a concentration of 1%), and E3 (rat induced to DMBA and capsaicin extract nanoparticle gel with a concentration of 3.3%). The data were analysed statistically with the one-way ANOVA and least significance difference (LSD) test. Results: The comparison of mean nodule volume between C+ (5.834 ± 2.77 mm3) with E1 (1.75 ± 0.37 mm3), E2 (1.747 ± 0.36 mm3), and E3 (1.812 ± 0.11 mm3) had a significant difference (p = 0.00, p ≤ 0.05). Conclusion: Capsaicin nanoparticle gel with green chilli pepper extract at levels of 1% (E2) reduces OSCC nodules by more than gel with green chilli pepper extract at 3.3% (E3) concentration.
