Background: There is strong evidence to support the claim that periodontitis may be more prevalent among diabetic individuals. Collagen degradation represents one of the key events in periodontal destructive lesions. The level of matrix metalloproteinase 8 (MMP-8) and tissue inhibitor of metalloproteinase 1 (TIMP-1) are key to periodontal collagenolysis and associated with the severity of periodontal inflammation and disease. Host modulatory therapy has been proposed as a treatment for periodontal diseases. Sardinella longiceps (lemuru) fish oil containing polyunsaturated fatty acids (PUFAs), including omega 3 and 6, has been shown to possess therapeutic anti-inflammatory and protective properties effective against inflammatory diseases, including periodontitis. Purpose: The study aimed to examine the effect of dietary supplementation of Sardinella longiceps fish oil on protection against periodontal destruction resulting from the expression of MMP-8 and TIMP-1. Methods: Wistar rat samples are divided into four groups: a negative control group and three groups receiving Sardinella longiceps fish oil treatment (4 ml/ weight (Kg), 8 ml/ weight (Kg) and 16 ml/ weight (Kg). One week before treatment, all groups were administered with streptozotocin (STZ) 65 ml/ weight (Kg) and nicotinamide 110 ml/ weight (Kg) to induce diabetic conditions. Immunohistochemistry slides of periodontal tissues were prepared after three weeks of treatment. The expression of MMP-8 and TIMP-1 was counted using the HSCORE index, data was analyzed by means of non-parametric methods using Kruskal-Wallis, and Mann-Whitney tests. Results: Statistical analyses confirmed a significant increase in MMP-8 expression and a reduction in TIMP-1 expression in the negative control group compared to the treatment group (p<0.05). Meanwhile, the treatment group showed a significant reduction in MMP-8 expression and a marked increase in TIMP-1 expression, with the best result produced by the administering of 16 ml/ weight (Kg) Sardinella longiceps fish oil to the treatment group (p<0.05). Conclusion: Dietary supplementation of Sardinella longiceps fish oil can protect against periodontal destruction under diabetic conditions, by decreasing MMP-8 expression and increasing TIMP-1 expression.

Objectives This study aimed to examine the impact of hyperbaric oxygen therapy (HBOT) on serum C-reactive protein (CRP) levels, osteoclast numbers, and osteoprotegerin (OPG) expression in periodontitis-induced diabetic rats Materials and Methods This study constituted an in vivo laboratory-based experiment incorporating a posttest only control group design. Thirty male Wistar rats were divided into three groups of research subjects: a healthy group (K0), periodontitis-induced diabetic group (K1), and periodontitis-induced diabetic group treated with HBOT for 7 days (K2). After treatment, the subjects were sacrificed to determine the level of serum CRP by the ELISA method. Immunohistochemical analysis was conducted to check the level of OPG expression, while a histological analysis was undertaken to quantify the number of osteoclasts. Statistical Analysis The data was analyzed using a one-way ANOVA and Least Significant Difference (LSD) test on which a result of p < 0.05 was considered statistically significant. Results HBOT appreciably decreased serum CRP levels, significantly enhancing OPG expression in periodontitis-induced diabetic (p < 0.05) and decreasing the number of osteoclasts in -periodontitis-induced diabetic (p > 0.05). Conclusion HBOT reduced the serum CRP level, increased OPG expression, and decreased osteoclast numbers in periodontitis-induced diabetic rats.

Methanolic extract from the leaves of Acanthus ilicifolius L. (A. ilicifolius L.) is a potent inhibitor of Candida albicans (C. albicans) growth and anti-inflammatory. C. albicans causes oral candidiasis in immunosuppressive condition. Mitogen-activated protein kinase (MAPK) signalling via p38 appears to discriminate between yeast and hyphal cells of C. albicans. Activation of p38 MAPK by hyphae results in the upregulation of proinflammatory cytokines. The p38 MAPK activation is known to impair corticosteroid action. The research was conducted to investigate the effect of methanolic extract A. ilicifolius L. treatment of oral candidiasis with the immunosuppressive condition through enhancement of p38 MAPK expression in the epithelial cells. Immunosuppressed conditions were obtained when 16 healthy male Rattus norvergicus (Wistar) was given oral administration of dexamethasone and tetracycline for 14 days and induced with C. albicans (ATCC-10231) 1 McFarland. The subjects were divided into four groups (n = 4/group): immunosuppression (IS), immunosuppression with oral candidiasis without treatment (ISC), immunosuppression with oral candidiasis and nystatin treatment (ISC+N), and immunosuppression with oral candidiasis and A. ilicifolius L. treatment (ISC+AI), and were treated for 14 days. Later, the rats were euthanised, and their tongue were biopsied. The p38 MAPK expression was subjected to immunohistochemical examination, observed under a microscope (400× magnification) and statistically analysed (one-way ANOVA, LSD-test, p < 0.05). The p38 MAPK expression of ISC+AI (36.05 ± 1.54) was higher than IS (26 ± 2.32), ISC (26.4 ± 3.71), IS+N (34.2 ± 0.99). Significant differences existed between ISC+AI and ISC+N to IS and ISC (p < 0.05). No significant differences were present between IS and ISC; ISC+AI and ISC+N (p > 0.05). Therefore, this treatment could enhance p38 MAPK expression in oral candidiasis with the immunosuppressed condition.

Background: Oral candidiasis is the most prominent oral fungal infection with Candida albicans (C. albicans) as 75% of ethiologic factor. Golden sea cucumbers (Stichopus hermanii) have been consumed by Asian community as folk medicine. It has been known to have antifungal and immunomodulator agent thus potential to be explored as treatment in oral candidiasis. Purpose: The aim of this study was to examine the potency of Stichopus hermanii extract as oral candidiasis treatment. Method: The study was an experimental laboratories research with post test only control group design. Thirty male wistar rats were divided into 5 groups i.e negative control, positive control and 3 treatment groups. Oral candidiasis condition were induced by spraying C. albicans suspension on dorsal tongue of wistar rats, once in 2 days for 14 days. The treatment groups were given Stichopus hermanii extract on the dose of 4.25 ml/kgBW, 8.5 ml/kgBW, 17 ml/kgBW once daily for 14 days. The expression of anti C. albicans antibody and TNF-α were examined by immunohistochemistry on ephitelial tongue. Data was analyzed by Manova and LSD test. Result: Anti C. albicans antibody expression were higher in positive control group than in negative control group while TNF-α expression were lower in positive control group than in negative control group (p<0.05). Treatment with Stichopus hermanii extract on all doses decreased the expression of anti C. albicans antibody and increased the expression of TNF-α (p<0.05). Conclusion: Stichopus hermanii extract decreased the expression of anti C. albicans antibody and increased the expression of TNF-α in epithelial rat tongue.
