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
@#Introduction: Biological process of wound healing in soft tissue injury which include some phase that its highly organized cascade, such as haemostasis, inflammation, proliferation and remodeling. Healing process will be impaired when there is an interference with one of the four of the phase not going well. This study is aimed to proving the role of dragon fruit peel extract towards the interpretation of TGF- β, fibroblast cell and formation of new blood vessels during wound healing process. Methods: 20 rattus norwegicus wistar strain rats are separated into four groups. The one lower incisor is extracted, afterward the wound post extraction of the treatment group was treated with dragon fruit peel extract gel with the concentration of 15%, 30% and 60%, meanwhile, for the control groups, they are treated with polyethylene glycol gel. On the fourth day, the rats were sacrificed and preparation of immunohistochemical and histopathology are made. Observe under the light microscope with 400x magnification. Results: This study shows that the 30% concentration increase the expression of TGF- β (16.6±2.07), fibroblast proliferation (77.6±5.27) and new blood vessels (33.8±2.28) compare to the control group, 15% and 60% concentration in a meaningful way (p=0.00, p=0.00 and p=0.00). Conclusions: The dragon fruit peel extract gel may affect the wound healing process of extraction by increasing the expression of TGF- β, number of fibroblast and formation of new blood vessels.
