The conclusion is fennel could reduce an inflammation and there is no difference of healing either by crushed or distilled fennel."

"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 215-220The purpose of this study was to disclose one of the etiopathogenesis of recurrent aphthous stomatitis (RAS) at molecular level by analyzing the expression of protein anomaly in oral mucosa. This was a cross-sectional explorative and analytic observational study. Samples, who met inclusion and exclusion criteria, were taken from total population. Samples of protein swab were obtained from oral mucosa, serum weretaken from 15 patients with major RAS, 20 patients with minor RAS and 15 were control. The characterization of protein anomaly expressed on the surface of oral mucosa epithelium was carried out using SDS-PAGE 12% and Westemblot methods. The result of oral mucosa protein anomaly expression analysis in patients with major RAS using SDS-PAGE 12% revealed five protein bands with molecular weights of 87,65, 30, 25, and 20 kDa. In minor RAS cases with protein anomaly expression there were four proteins with molecular weights of 87, 65, 25, and 20 kDa, and the protein in remission RAS had four proteins bands with molecular weight of 87, 65, 25 and 20 kDa. The band disappearances by using Westemblot test, of 30 kDa of major cases, 87 and 20 kDa of minor cases and 20 and 25 kDa of remission cases, indicated that those patients were not reacted with polyclonal antibodies of rabbit serum; therefore they had no role in the induction of RAS. ln conclusion, the antigenic protein expressed in oral mucosa of major, minor, and remission RAS was predominantly 65 kDa molecular weight."

ABSTRACTBackground: Long-term aspirin therapy can induces gastroduodenal mucosal injury, even in a very low dose (10 mg daily). The frequency of gastroduodenal injuries among long-term low-dose aspirin users in Indonesia is currently unknown.Aim: To determine the gastroduodenal mucosal injury prevalence, endoscopic findings, and influencing factors among long-term low-dose aspirin users in RSCM. Methods: This study was a cross-sectional study conducted in Cipto Mangunkusumo Hospital, Jakarta. Subjects were ≥ 18 years old patients that have been using low-dose aspirin (75-325 mg) for at least the preceding 28 days. Ninety five subjects were recruited consecutively in the period of December 2015 ? April 2016. Endoscopic findings such as erosions and ulcers were assessed as mucosal injuries. Results: Mucosal injury was found in 49 subjects [51.6% (95% CI 41.6?61.7%)]; mucosal erosion in 38 subjects [40% (95% CI 30.2?49.9%)] and ulcers in 11 subjects [11.6% (95% CI 5.2?18.0%)]. Only 44.9% patients with mucosal injury had dyspepsia symptoms. Double antiplatelet therapy increases the risk of mucosal injury [OR 3.3 (95% CI 1.3?8.5)]. However, proton pump inhibitor (PPI) decreases the risk [OR 0,2 (95% IK 0,04 ? 0,60)]. Conclusions: Gastroduodenal mucosal injury was found in more than half of long-term low-dose aspirin users. Double antiplatelet therapy increases the risk of mucosal injury, while PPI effectively reduced the risk.;"

"Recurrent Aphthous Ulceration (RAU) is a type of local inflammation of the oral mucosa with symptomatic soft tissue damage. The prevalence of RAU is about 17-67 %. Dominant factors causing this disease are understood, but there are predicted internal and external factors that cause related immune disorders. RAU is initiated by mucous proteins which continuously stimulate a physiological response required for a pathophysiological reaction. The aim of this study was to characterize specific anomaly proteins in oral mucosa as causing the initiation of RAU. Samples of mucosal proteins from 30 RAU patients were analyzed with sodium dodexylsulphate polyacrylamid gelelectrophorese (SDS-PAGE) and visualized with silver stain (AgNO3) showing proteins with a range of molecular weight 27 - 180 kDa. Western blotting using a polyclonal antibody specific to RAU showed that the specific proteins of RAU have molecular weights of 23, 27, 65, 70 and 87 kDa. The finding of so many proteins appears to be a new phenomenon, suggesting that the initiation of RAU is possibly due to a continuous induction of internal and external reactions by several mucosal proteins, that become anomaly proteins of high reactivity and antigenicity. This situation can cause overreaction on the oral mucosa with specific symptoms that are known as a RAU."
