Abstract

Background: Therapy for chronic ulcer in diabetic patient is by modifying local inflammation response using drugs that acts as immunomodulator, neuromodulator and growth factors stimulator. Topical zinc is one of drug that can modifiy local inflammation response, immunostimulation or immunosuppresion. Purpose: This study was to prove about the number of macrophage in oral ulcer between normal and diabetes microscopically and the difference if treated by 1% ZnSO4 gel topically. Method: Ulcer in lower labial mucosa was made in normal and diabetic Wistar rats (induced by STZ), then applied 1% ZnSO4 gel and CMC-Na gel as control. They were decapitated in third and fifth day and specimen was made by processing lower labial mucosa Result: Microscopically, the result showed the number of macrophages in oral ulcer in diabetic condition was significantly higher than normal and the application of 1% ZnSO4 increased the number of macrophages in fifth day. Conclusion: The number of macrophages was higher in diabetic than normal condition, and was proven that topical application of 1% ZnSO4 increased the number macrophages of oral ulcer diabetic and normal condition.

Abstract

Background: The most common fungal infection found in oral cavity is oral candidiasis, largely caused by Candida species, particularly Candida albicans (C. albicans). Candida infection can get worse since it is difficult to be treated and resistant with antifungal drugs. Therefore, new drugs and compounds as well as alternative therapies involving natural sources that have antifungal activities have continually been developed. Limonene, β-pinene, and ɣ-terpinene contained in Citrus limon essential oil have been known to have quite good antifungal activities against C. albicans. Purpose: This research aimed to examine and analyze the effects of Citrus limon essential oil on cytomorphometric changes of C. albicans. Method: The research used post test only control group design. Based on the results of the pre-elementary research on antifungal activities of Citrus limon essential oil against C. albicans, Citrus limon essential oil used in this research was on concentrations of 1.56%, 1.37%, 1.17%, 0.98%, and 0.78%. Citrus limon essential oil by C. albicans inoculum and incubated for 24 hours and 48 hours. After the incubation, those C. albicans cells were fixed, dried, and then observed using a scanning electron microscopy. Result: The most effective concentrations of Citrus limon essential oil triggering cytomorphometric changes of Candida albicans were at 1.37% and 1.56% with the incubation period of 48 hours. Conclusion: C. albicans can undergo necrosis process through cytomorphometric changes after the administration of Citrus limon essential oil at concentrations of 1.56% and 1.37% with the incubation period of 48 hours.
