Osteoblast Viability of Liquid Smoke Rice Hull and Nanoparticles Form as Periodontitis Treatment.

OBJECTIVE: Rice husk liquid smoke nanoparticles have the potential to be developed as a drug because they have anti-inflammatory effects that can modulate the process of osteoblast stimulation through osteoblast stimulation by thorough small size and enter cells easily. The osteoblast is the key of alveolar regeneration in periodontitis treatment. This present study analyzed the differences of liquid smoke rice husk and nanoparticles of liquid smoke rice husk on osteoblast viability as periodontitis treatment MATERIALS AND METHODS: The liquid smoke rice husk was obtained from the pyrolysis process. The nanoparticles were made with chitosan, maltodextrin, and difference of concentration of liquid smoke rice husk (such as 1, 2.5, 5, 7.5, 10, 12.5, 15, and 17.5%). The viability of osteoblast was analyzed by 2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. STATISTICAL ANALYSIS: The data were analyzed using independent t-test to analyze the differences between liquid smoke rice husk and nanoparticles of liquid smoke rice husk, the significant was set a p<0.05. RESULT: The nanoparticles of liquid smoke rice husk showed higher osteoblast viability compared liquid smoke rice husk. The nanoparticles' concentration of 5, 7.5, and 10% showed higher osteoblast viability compared liquid smoke rice husk (p = 0.002, 0.000, and 0.001, respectively). CONCLUSION: The nanoparticles of liquid smoke rice husk showed higher viability of osteoblast. This confirmed that the nanoparticles were able to reduce the toxicity in the higher concentration of liquid smoke of rice husk.

In Silico Study of Liquid Smoke Rice Husk against COVID-19.

OBJECTIVES: Liquid smoke rice husk has been researched and proved to consist of antibacterial, analgesic, anti-inflammatory, and growth factor stimulatory properties. By these complex properties, the liquid smoke rice hull is able to purpose as a novel coronavirus disease 2019 (COVID-19) inhibitor. The research was conducted to analyze the role of the dominant compound in rice husk liquid smoke against one of the main proteases in complex with inhibitor N3 of COVID-19 and 6LU7 protein data bank (PDB) ID. MATERIAL: AND METHODS: The Molecular Operating Environment (MOE) 2020.0901 (Chemical computing group) was used to analyzed the interaction. The molecular structure test, including phenol, mequinol, 2-methoxy-phenol, 6-octadecenoic acid, oleic acid, 9-cctadecenoic acid, was chosen. The lopinavir as positive control and 6LU7 as COVID-19 protein were chosen. All the protein analyses were conducted using docking molecular. RESULT: The phenol, 2-methoxy-phenol, mequinol and 9-octadecenoic acid have higher binding free energy that causes difficult to bind to the active site of protein 6LU7 (-3.4758, -3.5509, -3.6845, and -5.0173 kcal/mol, respectively). The minor component of liquid smoke, such as 6-octadecenoic acid and oleic acid, has the binding free energy (-5,5327 and -5,4208 kcal/mol) and more factor of binding presumably as active COVID-19 inhibitor. CONCLUSION: The liquid smoke rice husk has active component like 6-octadecenoic acid and oleic acid are presumably as active COVID-19 inhibitor.

Formulation, characteristics and anti-bacterial effects of Euphorbia hirta L. mouthwash.

Objective: Mouthwash is a liquid solution used to improve oral health and breath freshness as well as reduce oral bacteria. This study aims to formulate a Euphorbia hirta L. ethanol extract for mouthwash, evaluate the physical properties, and determine its anti-bacterial effects against Streptococcus mutans. Methods: Each mouthwash formula was created by utilising a solubilisation technique. Three mouthwash formulas were created from different concentrations of Euphorbia hirta L. ethanol extract (0.5%, 1%, and 2%), and referred to as F1, F2, and F3. The organoleptic properties, pH levels, specific gravity, viscosity, flow properties, stability, irritation level, contact time, and anti-bacterial effects were evaluated for each concentration. Result: The resulting formulas featured a distinctive smell of oleum menthae piperitae and had a sweet and spicy taste. These characteristics remained unaffected during storage. The acidity levels ranged from 4.59 to 6.0, the weight masses ranged from 0.9693 to 1.0710 g/ml, and the viscosity ranged from 1.50 to 3.00 cP. F3 concentration was non-irritating with mucus production at 11.325%, had lower contact time with a neutralisation of 57.14% of Streptococcus mutans colonies in 30 seconds, and showed stable anti-bacterial control against Streptococcus mutans (p = 0.000) within the first week of use. Conclusion: The study results offer the first proof of Euphorbia hirta L. used for improving human health. The formulation features the ideal physical and stability characteristics of mouthwash, and possesses anti-bacterial properties that can potentially combat Streptococcus mutans. Clinical use of the formulated mouthwash must be explored in future research.

Oral squamous cell carcinoma with essential thrombocythemia and positive JAK2 (V617F) mutation.

Essential thrombocythemia is a condition caused by a high platelet count and a positive JAK2 (V617F) mutation. There is an increasing occurrence of malignancy, such as oral squamous cell carcinoma (OSCC), in patients with essential thrombocythemia. The objective of this case report is to document the novel instance of a patient with OSCC after being diagnosed with essential thrombocythemia and a positive JAK2 (V617F) mutation. The patient was a 42-year-old female who complained of an ulcer and pain in the dextral lateral tongue for three months. After two weeks, the pain diminished; however, there was swelling and tenderness on the ulcer. The patient was diagnosed with essential thrombocythemia and a positive JAK2 (V617F) mutation and began undergoing hydroxyurea therapy three months prior to the OSCC diagnosis. The diagnosis of OSCC was based on exfoliative cytology and MRI. The patient was treated with an antiseptic mouthwash to prevent secondary infection and referred to an oncologist to manage the OSCC. It is possible to use the suspected markers of thrombocytosis and a positive JAK2 (V617F) mutation to define the OSCC diagnosis.

Growth factor stimulation for the healing of traumatic ulcers with liquid rice hull smoke.

OBJECTIVE: The healing process of a traumatic ulcer requires growth factors to rebuild the lost tissue after the inflammatory process has been completed. Liquid rice hull smoke (LR-HS) has shown unique anti-inflammatory properties. This study analyses the role of LR-HS in growth factor stimulation for the healing of traumatic ulcers, such as fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and collagen type 1 (COL-1) expression. METHODS: We obtained LR-HS from the pyrolysis of rice hulls. Traumatic ulcers were created in the labial fornix incisive inferior of Wistar rats and treated with LR-HS once a day for 3, 5, and 7 days. The control group was treated with sterile water. Each animal was sacrificed after treatment, and its labial fornix incisive inferior tissues were biopsied and immunohistochemically stained to examine FGF, VEGF, PDGF, and COL-1 expression. RESULT: The treatment of traumatic ulcers with LR-HS showed an increase in FGF, VEGF, PDGF, and COL-1 expression. VEGF expression increased under LR-HS treatment compared with the control 7-day treatment groups (p < 0.000). FGF and COL-1 expression increased under LR-HS treatment compared with the control 5- and 7-day treatment groups (p < 0.000). PDGF expression increased after treatment with LR-HS for 3, 5, and 7 days (p < 0.000). CONCLUSION: This study has demonstrated that LR-HS can induce the expression of growth factors during the healing of a traumatic ulcer using immunohistochemical staining. We suggest that LR-HS can be used as a herbal medicine for oral ulcer therapy.
