Researches of Thai Herbs for Osteoarthritis Treatment

งานวิจัยสมุนไพรไทยสำหรับการรักษาโรคข้อเสื่อม

วารณี ประดิษฐ์ สิริวดี ชมเดช และ กรกฎ งานวงศ์พาณิชย์

Osteoarthritis is a chronic joint disease mostly found in elder people and animals. Gradual degradation of articular cartilage is the important symptom causing joint pain. Pathogenesis of this disease is complex and involves with many responsive mechanisms particularly inflammation. This mechanism can induce imbalance of joint homeostasis resulting in over production of enzyme that could digest extracellular matrix components of cartilage. Treatment of osteoarthritis using analgesic drugs including non-steroidal anti-inflammatory drugs (NSAIDs) is only one way to alleviate pain which brings some unwanted side effects. Nowadays, searching of plant extracts which has potential to resist inflammation with chondroprotective properties for osteoarthritis treatment has been increasing continuously. There are some scientific evidences showing the efficiency of some common Thai herbs for anti-arthritis. This article reviewed the efficacy and proposed mechanisms of some Thai herbs including turmeric, ginger, betel and moringa that can relieve osteoarthritis symptoms particularly inflammation and pain management.

3D Electron Backscattered Diffraction by Using Focused Ion Beam

การเลี้ยวเบนของอิเล็กตรอนกระเจิงกลับแบบ 3 มิติโดยใช้ลำไอออน

นาท เสาวดี

Electron backscattered diffraction (EBSD) is an electron microscopic technique used in investigating of specimen crystallographic grains and grain boundaries in solid crystalline. This technique is mainly used to measure crystal orientation of grains in a specimen. This information is used in analysis of microstructural properties of the crystalline. Two dimensional crystal orientation maps cannot provide information about grain boundaries inclination and true structure of grains and grain boundaries. In specific site analysis for deep detail, it needs 3D orientation map. Currently, a technique widely used in 3D-EBSD data collection is using focused ion beam (FIB) serial sectioning. In the technique, the specimen is milled by the FIB to create a new plane and 2D-EBSD data on each milled plane is collected. The data set is restacked to reconstruct 3D-EBSD. Material issues to be considered in 3D-EBSD data collection are material’s conductivity, complexity of crystal structure and surface damage due to FIB milling.

The objectives of this study were to compare the raw material qualities (degraded solar dried banana) of four experimental samples (different storage times at 4oC), and to evaluate the optimal storage times of degraded solar dried banana for banana syrup production. The physical, chemical and microbiological qualities of raw materials which stored for 4 different storage times (7, 14, 21 and 30 days) at 4oC were significantly different (P≤0.05). The results showed the color, moisture content, total acidity (lactic acid), the microbial quantities such as total count, yeast and mold count and lactic acid bacteria were increasing when the storage time was increased. However, total soluble solid (TSS), and pH were decreasing. Four samples of solar dried banana syrup were obtained by extraction of solar dried bananas with added pectin digested enzymes. The yield of those were ranging from 30.49–32.67% (v/w) and its qualities were significantly different (P≤0.05). L*, b* values and pH were determined ranging from 7.48–13.1, 1.40–3.59 and 3.80–4.49 respectively. Consequently, solar dried banana syrups contained 2.22–4.27, 2.49–3.66 และ 1.85–3.66 log CFU/ml of total count, yeast and mold and lactic acid bacteria respectively. In the conclusion, degraded solar dried banana exhibited good potential as substrate for banana syrup production; however, it should not be stored more than 21 days. คำ

พรทิพย์ อติชาติ

This research was conducted to study survival rate and cell characteristic of Dendrobium chrysotoxum after treated with colchicine. The protocorms were submerged in various concentrations of colchicines (0, 0.01, 0.02, 0.03, 0.04 and 0.05%) for 1, 2, 3, 4 and 5 days. The survival rate, chrolophyll content and size of parenchyma cell were evaluated after two months of the culture on Vacin and Went (1949) medium. It was found that higher concentration of colchicine and longer treatment duration reduced protocorm survival. Chrolophyll content of treated protocorms were higher than the control. The treated protocorms with 0.03% colchicine for 1 day provided the largest parenchyma cell (107.77±6.08 μm in diameter). Whereas the largest size of parenchymatous nucleus could be observed when protocorms were treated with 0.05% colchicine for 2 days.

Reduction of Earthy-flavour and Geosmin content in Frozen Thai Panga Fish (Pangasius sp.) Fillets

การลดกลิ่นโคลนและปริมาณสารจีออสมินในเนื้อปลาสวายโมงแล่แช่แข็ง

ปิยะวิทย์ ทิพรส

Thai Panga fish (Pangasius sp.) is promoted as an economic freshwater fish in Thailand. Geosmin (GSM) caused an earthy odour which was unacceptable to consumers. The purpose of this study is to compare the effects of ozone, banana leaf ash or sodium chloride solutions (NaCl) on reducing GSM off-flavor and quality acceptance of Thai Panga fish fillets after one frozen-thawed cycle. The preliminary study showed that the freshness of fish is acceptable to assessors. Proximate chemical and nutritional evaluations were presented as follows: pH 5.98, TVB-N (4.85 mg-N/100g), Omega-3 (173 mg/100g), Omega-6 (831 mg/100g), Omega-9 (2,536 mg/100g), and without trans fatty acid. The Thai Panga fillet samples were defrosted at a temperature 15°C. The fish were single fillets to ensure that the fatty tissue of the fish (where off-flavors are most likely to deposit) was still attached. Sub-samples of Thai Panga fillets were spiked in several spots with a syringe just underneath the skin with 200 ng/L of the standard GSM solution. It was then placed into a PE-plastic Ziploc bag and frozen for at least 12 hours at -21oC. After the Thai Panga fish fillets were exposed to ozonated water (200 or 400 mg/L), banana leaf ash (3% or 5% w/v) or sodium chloride (3% or 5% w/v) solutions, all treated samples including the control sample were analyzed for GSM by SPME-GC/MS analysis. The results showed that in all of the treatments (pH 6.54-6.93) there was no detection of the GSM content by SPME-GC/MS in all samples, which corresponds to the scoring test by assessors that all interaction treatment effects could not be detected for the GSM off-flavour when cooked by microwave, except the fish fillets contacted with 3% NaCl which had slightly GSM off-flavour (4.27). In addition, the 9-point hedonic scale sensory evaluation by trained assessors presented that all treatment and /or interaction effects displayed fairly to very good acceptibility.

The research was to design and develop shell-and-tube and coil-tube economizers for once-through boiler generating steam with 250 kg/h steam producing rate at 408 kPa pressures. The measured temperature of exhaust gas boiler was 453 K entering the cross-flow economizer used to preheat the feeding water with the heating surface area and tube length of 3.55 m2 and 34 m. The research found that the economizer shell and tube exhaust with gas at 7.65 m/s produced the heat transfer coefficients of the tube outer and inner area at 33.42 and 5.71 W/m2K, respectively while the pressure drops for shell and tube were 25.69 and 2.27 Pa. The effectiveness of the economizers was 0.40 and the energy saving cost was 78,600 Baht/year. The payback period is around 2.66 years. When compared the coil tube economizer exhaust gas at 5.33 m/s, the heat transfer coefficient of the tube outer and inner area were 54.42 and 0.89 W/m2K, respectively while the pressure drops for shell and tube were 87.42 and 0.65 Pa. The effectiveness of the economizers was 0.36 and the energy saving cost was 75,300 Baht/year. The payback period is around 2.52 years. The compared shell-and-tube economizer and coil-tube economizer were suitable for once-through boilers generating steam of 500 kg/h rate at pressure steam test of 102-408 kPa.

การเพิ่มสมรรถนะการถ่ายเทความร้อนในท่อสี่เหลี่ยมจัตุรัส โดยตัวสร้างวอร์เทคแผ่นติดครีบวีคู่

ธีรพัฒน์ ชมภูคำ

The paper presents an experimental study on turbulent flow and heat transfer characteristics in a square duct fitted diagonally with double V-ribbed tapes. The tested duct has uniform heat-fluxed walls and the flow rate of air used as the test fluid is presented in terms of Reynolds number from 4,000 to 25,000. The insertion of the ribbed tape is performed with three blocked ratios of rib-to-duct height (b/H) = 0.10, 0.15 and 0.20, three attack angles () = 20, 30 and 45, pitch ratios of rib pitch to duct height (PR = P/H) = 1 and pointing downstream of the flow with respect to the main flow direction. Influences attack angles and blocked ratios on thermal and flow friction characteristics of the inserted duct are investigated. The experimental result of heat transfer in the form of Nusselt number and pressure drop in term of friction factor are compared between the duct mounted with double V-ribbed tapes and the smooth duct. The experimental result shows that the rise of the attack angle and the blocked ratio results in the increase in Nusselt number and friction factor values. The maximum thermal performance is found to be 1.92 for using the ribbed tape at  = 20 and BR = 0.20 at the lowest value of Reynolds number.

การจำลองพลวัตเชิงโมเลกุลสำหรับกระบวนการแพร่ของก๊าซผสมระหว่างไฮโดรเจนและมีเทนในวัสดุโครงข่ายโลหะอินทรีย์ชนิด Zn(tbip)

คมพิชิต สีหามาตย์

Molecular dynamics simulations were used to study the diffusion of H2, CH4 and their equimolarmixtures inmetal-organic framework Zn(tbip) at 298 K. The results were analyzed to obtain the self-diffusivities ( s D ) and the diffusion selectivities ( diff S ) of the molecules. In both pure and mixture, the s D values of H2are in the range of 2.0×10-8-1.0×10-7 m2/sandlarger than that of CH4, 3.0×10-9-2.0×10-8 m2/s. In mixtures, the diff S was determined to be different from the Knudsen selectivity ( diff ,Kn S ), giving the values of , / diff diff Kn S S in the rage of 1-2.5. This different is attributable to the fact that methaneis more strongly adsorbed than hydrogen at pore walls of Zn(tbip). The diff S values are in the range of 3-7, indicating that Zn(tbip) can be useful for separating H2/CH4 mixtures.

Using Generalized Linear Models in Analysis of Risk Factors to Infant Death Considering from Birth Weight of Infant

การใช้ตัวแบบเชิงเส้นนัยทั่วไปในการวิเคราะห์ปัจจัยเสี่ยงต่อการเสียชีวิต ของทารกที่พิจารณาจากน้ำหนักแรกเกิดของทารก

จุฑามาศ สสิโรจน์ ชฎายุรัตน์ ชิตชิกูล ดารารัตน์ ศรีเดช และ วีรานันท์ พงศาภักดี

The analysis of risk factors to infant death considering from birth weight of infant has been performed by classifying the birth weight into 3 categories: risky group, monitored group, and normal group. The risk factors obtained from literature reviews consist of mother age, smoking during pregnancy, premature labor, historical hypertension, and uterine irritability from the real data set of 189 babies (Hosmer and Lemeshow, 1989). The models under consideration are cumulative logit model, logit model for binary response, loglinear model, and Poisson regression model compared with generalized Poisson regression model. The results reveal that every model provides significance at 0.05 for goodness-of-fit test. The three risk factors affecting the response of cumulative logit model and the logit model are the same: premature labor, historical hypertension and uterine irritability. From loglinear model, history of hypertension and presence of uterine irritability are obtained. From Poisson regression model, the age of mothers is obtained. Hence almost all risk factors under studies, except for the smoking during pregnancy, are statistically affecting the birth-weight risk of death significantly at 0.05 with a highly predicted probability of a corresponding model.

This research aimed to study the problems, managerial ways, and quantities, compositions and characteristics of solid waste in Surindra Rajabhat University (SRRU), Surin, Thailand. The results found that there were 302 kg/d and 0.023 kg/c/d of the solid waste average quantity and production rate, respectively. The compositions were 37.49%, 24.95%, 23.88% and 13.68% of paper, plastic, recycled plastic bottle and food waste, respectively. With regards to the problems and managerial ways of solid waste, students and staffs had the knowledge of solid waste and its management at medium level equal to 53.76%. The problem condition of solid waste was in the highest severe level at 4.19±0.87. The satisfactions in working performance and in university community participation of solid waste management were in high levels at 3.74±1.09 and 4.00±0.96, respectively. However, students and staffs had the knowledge of solid waste and its management at medium level and the satisfactions of the working processes and participation were at high level, but the severe problem conditions were still at highest level. Therefore, SRRU should urgently have a training project about solid waste and its management. The managerial ways of solid waste in SRRU need to be improved in terms of collection, separation (must have separate-type waste containers), recycling system, and solid waste removal system (incinerator or sanitary landfill). Besides, university administrators should distinctively create an environmental policy as zero-solid waste discharge and support campaigns for creating awareness of students and staffs in solid waste management.

A study of the types and amount of airborne micro-organisms that cause allergies and infections found in six laboratories in the Faculty of Science, Payap University was carried out. A settle plate method was used to collect airborne microbes in a four-week period between January to February 2012. Samples were taken each day, in the morning and early afternoon. The results showed that the average amount of bacteria in the morning in the six rooms were in a range between 10.1 to 93.1 CFU/plate/h. By the afternoon they were between 4.9 to 63.9 CFU/plate/h. The average amount of fungus in the morning samples was between 32.1 to 87.0 CFU/plate/h and by the afternoon in the range between 17.1 to 76.3 CFU/plate/h. The average microbial count in the morning samples was higher than the afternoon. Comparison with The Index of Microbial Air Contamination (IMA) found average levels in the six rooms were very good to very poor. Six types of airborne pathogens were found: Bacillus sp. appeared the most, followed by Staphylococcus aureus and gram-negative rods, respectively. The greatest number of fungi was Penicillium sp. followed by Aspergillus sp. and Curvularia sp., respectively. We also found the allergy causing fungus Cladosporium sp. in high-volume in the laboratories. It was found that the relationship between the amount of bacteria and fungi in all the six laboratories were different with statistical significance (p<0.05). The relationship between the number of microorganisms in the air at different times in the morning and afternoon also found a statistically significant difference (p<0.05).

Protein Modification Using Proteases and its Applications

การดัดแปรสมบัติของโปรตีนโดยใช้เอนไซม์โปรติเอสและการประยุกต์ใช้

เกียรติศักดิ์ ดวงมาลย์ และ บูรฉัตร ศรีทองแท้

Proteolytic enzymes catalyse hydrolysis of peptide bond in proteins resulting in oligopeptides, peptides and amino acids. The functional properties of modified protein are different from those of native proteins. The properties of modified protein can be monitored through degree of hydrolysis (DH). Limited proteolysis, partial hydrolysis at low DH, causes a change in conformation, molecular weight distribution, stability, flexibility and interfacial properties of modified protein. These changes affect solubility, water holding capacity, emulsifying properties and foaming properties. Extensive proteolysis occurs at high DH. The obtained product contains a large amount of peptides and free amino acids compared to limited proteolysis. Some of these peptides not only improve nutritional value but also possess regulatory functions in humans and health benefits. Thus, applications of modified protein with different degree of hydrolysis in food product is dependent on its functional properties and the objective of utilization.
