ABSTRACT
@#Introduction: Cancer is one of the leading causes of deathworldwide. Chemotherapy like as doxorubicin is the most common treatment procedure given to cancer patients. Doxorubicin is a cytotoxic drug that triggers the production of Reactive Oxygen Species (ROS) affect to body cells including taste bud cells to induced the expression of Metallothionein 3 (MT-3), eventually cause cell damage that leads to a metallic taste. Antioxidant therapy can be an alternative to overcome metallic taste as it counters ROS effect and lowers the expression of MT-3. The aim of this study is to evaluate MT-3 expression in the taste bud cells of male Wistar Rats after induction of doxorubicin combined with vitamin E and mung bean sprouts (Phaseolusradiatus L.) juice. Methods: 27 male Wistar rats weighing 250-300 g aged 3-4 months were divided into 3 groups randomly; control group, treatment group 1 (receiving doxorubicin and vitamin E), and treatment group 2 (receiving doxorubicin and mung bean sprouts juice). After 5 days, the rats were sacrificed, and the tongue was taken for immunohistochemistry analysis. Data were then analyzed by One Sample Kolmogorov-Smirnov, Levene Test, and Oneway-ANOVA statistical test (p<0.05). Results: The MT-3 expression increases in the following order; control group (4.93), treatment group 2 (7.08), and treatment group 1 (9.95). Treatment group 1 and 2 both show remarkable increases of MT-3 expression compare to control. Conclusion: The induction of doxorubicin and antioxidant can increase the level of MT-3 expression.
ABSTRACT
@#<p style="text-align: justify;"><strong>INTRODUCTION:</strong> The healing process of tooth extraction is desired to take place faster to restore the normal tissue. Physical exercise is proven to accelerate wound healing through various physiological mechanisms. Aerobic exercise increases oxygen perfusion which leads to wound healing process. On the other hand, anaerobic exercise stimulates reactive oxygen species and may interfere with the wound healing process.</p><p style="text-align: justify;"><strong>OBJECTIVE:</strong> To observe if there are differences in the effectiveness of wound healing after tooth extraction based on the number of fibroblast and neovascularization in Wistar rats (Rattus norvegicus) that performed interval aerobic or anaerobic exercise.</p><p style="text-align: justify;"><strong>METHODS:</strong> Rats were divided into 3 groups, a control group and two treatment groups which performed the aerobic physical exercise or the anaerobic physical exercise. Fibroblast and neovascularization were calculated 7 days after the tooth extraction. Data were analyzed using Krusskal-Wallis statistical tests.</p><p style="text-align: justify;"><strong>RESULTS:</strong> The aerobic exercise group showed the higher number of fibroblasts and neovascularization compared to anaerobic exercise group, while the control group showed the lowest number of fibroblast and neovascularization.</p><p style="text-align: justify;"><strong>CONCLUSION</strong>: This study demonstrated that aerobic physical exercise accelerates wound healing in the proliferation phase better than anaerobic exercise and no exercise.</p>

Background@#Traumatic ulcer is a lesion formed by a local tissue damage due to trauma on epithelial layer. Vascular Endothelial Growth Factor (VEGF) plays an important role in wound healing, especially in angiogenesis. Golden sea cucumber (Stichopus hermanni) is believed to accelerate the wound healing process. @*Objective@#To prove that golden sea cucumber extract can increase VEGF expression in oral mucous membrane traumatic ulcer in rat.@*Method@#S. hermanni extract was prepared by freeze-dry method, then an extract was made using PEG 400 or PEG 4000 at 40% and 80% concentrations, respectively, and applied to the animal’s oral wounds. The animals were divided into three groups: control; 40% S. hermanni extract gel; and 80% S. hermanni extract gel. The ulcers that formed on day 3 were rubbed gently with S. hermanni extract gel. After being sacrificed on day 4, sample tissues from the lower lips were prepared for histopathology to count the number of VEGF expression. The results were analyzed using the One-Way ANOVA statistical test. @*Results@#A significant increase in the VEGF expression of 80% concentration S. hermanni extract gel was found compared with those in the control group (p=0.00).@*Conclusion@#Golden sea cucumber extract (Stichopus hermanni) gel increased the VEGF expression in oral mucous traumatic ulcer.
