  • Allelopathic inhibition by substance(s) originated from sicklepod(Cassia tora L.) seed on germination of other plant seeds, was confirmed and used to elucidate general mechanism of allelopathy which was occurred widly in natural and/or agricultural ecosystems. The mechanism was deduced from changes in water contents, ${\alpha}$-amylase activities, protease activities, concentrations of abscisic acid and total phenolic compounds during germination of rice and radish seeds treated with water-soluble extracts of sicklepod seeds. The results obtained were summarized as follows. 1. The % germinations of radish, rice, lettuce, barley seeds were decreased by substances originated from crushed sicklepod seeds. 2. By the treatment of water-soluble extracts of sicklepod seeds, the inhibition of germination of radish seeds was occured with the sequential phenomena of increase of protease activity(synthesis), decrease of water content and increase of total phenolic compounds content. 3. In rice, the inhibition of seed germination by the water-slouble extracts of sicklepod seeds was related to increase of abscisic acid concentration and then decrease of ${\alpha}$-amylase activity(synthesis).

  • This study was aimed to examine the antibacterial and antioxidative properties of seven edible plants from Thailand to develop alternative antibiotics as feed additives. The plants include Citrus aurantifolia Swingle (Lime) fruits and its leaves, Sesbania grandiflora L. (Agati sesbania) leaves, Piper sarmentosum Roxb (Wild betal) leaves, Curcuma domestica Valeton (Turmeric) roots, Morinda citrifolia L. (Beach mulberry) leaves, Cassia siamea britt (Siamea cassia) leaves, and Cocos nucifera L. (Coconut) peels. The plants were extracted by methanol, n-hexane, chloroform, ethyl acetate, butanol and water. Antibacterial activities with minimum inhibitory concentration (MIC) were determined by agar diffusion assay against Escherichia coli, Burkholderia sp., Haemopilus somnus, Haemopilus parasuis, and Clostridium perfringens that were considered pathogenic strains in livestock infection. Methanol extracts of C. aurantifolia Swingle fruits and leaves showed the broadest spectrum of antibacterial activities except for C. perfringens. Butanol extract of S. grandiflora L. leaves showed the strongest activity against Burkholderia sp. with MIC, $135{\mu}g/mL$. P. sarmentosum Roxb leaves showed antibacterial activities against E. coli, Burkholderia sp. and H. parasuis. Ethyl acetate and water extracts from C. domesitca Valeton roots showed MIC of $306{\mu}g/mL$ and $183{\mu}g/mL$, respectively against only C. perfringens. Antioxidative activity was determined by 2-diphenyl-2-picryl hydrazyl photometric assay. The methanol extracts of C. aurantifolia Swingle fruits and P. sarmentosum Roxb leaves showed the highest antioxidant activity among all the extracts with 3.46 mg/mL and 2.70 mg/mL effective concentration 50% ($EC_{50}$) values, respectively. Total contents of phenolics and flavonoids were measured from the plant extracts. Methanol extracts of S. grandiflora L. and chloroform extracts of C. domestica Valeton were found to have the highest amount of total phenolics, 41.7 and $47.8{\mu}g/mL$, respectively. Flavonoid content of methanol extracts in S. grandiflora L. T was $22.5{\mu}g/mL$ and the highest among plant extracts tested. These results indicated that C. aurantifolia Swingle, S. grandiflora L., P. sarmentosum Roxb, and C. domestica Valeton have antibacterial and antioxidant activities and can be used as alternative antibiotics or potential feed additives for the control of animal pathogenic bacteria.

  • Four cropping systems, soybean mono-cropping, Cassia tora mono-cropping, soybean-C. tora companion cropping and soybean-C. tora intercropping, were compared for number of soil nematodes and soybean growth in upland field in 1986. Soybean was cultivated as an after-crop of four different cropping systems from 1987 to 1989, and observations were continued. Soil nematode was not found in C. tora mono-cropping plot from mid growing season of C. tora while many nematodes were found in soybean mono-cropping plot in 1986. A few nematodes were found for 3 years in soybean field after one season cultivation of C. tora in 1986. Number of nematodes was lower in soybean-C. tora companion and inter-cropping plots compared with soybean mono-cropping, and was also lower for 3 years in soybean field after one season companion and inter-cropping culture in 1986 compared with continuous soybean cultivation plot. No root nodule was formed on C. tora root, but number of root nodules of soybean plant grown in C. tora companion and inter-cropping plots was not different with soybean mono-cropping plot. Number of pods. number of seeds and seed weight per soybean plant grown in C. tora companion and inter-cropping plots were almost same with soybean mono-cropping plot. When soybean was cultivated in field after one season C. tora mono, companion or inter-cropping, pod and seed number, and seed weight per plant were higher than continuous soybean cultivation field.

  • This study was undertaken to investigate the effect of Cassia tora ethanol extract on the lipid levels in serum and liver of rats fed high cholesterol diet. Experimental rats were divided into the following 4 groups: normal diet group, high cholesterol diet group, high choleslerol-0.25% C. tora ethanol extract group and high cholesterol-0.5% C. tora ethanol extract group. After 4 weeks, rats were sacrificed and analyzed the serum lipid profiles, activities of serum alanine aminotransferase (AST), aspartate aminotransferase (ALT), hepatic glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme (ME). It was also determined the contents of total cholesterol, triglyceride and thiobarbituric acid reactive substances (TBARS) in liver. There was no difference in weight gains between experimental groups. The concentrations of serum total cholesterol, free cholesterol, triglyceride and free fatty acid were tended to be decreased in C. tora groups compared with control group. HDL-cholesterol concentration was significantly decreased in high cholesterol diet group and slightly increased by C. tora ethanol extract feeding. The contents of liver cholesterol and triglyceride were higher in high cholesterol diet group than normal group, but significantly decreased by feeding of C. tora ethanol extract. Supplementation of 0.5% C. tora extract decreased significantly the activities of hepatic G6PDH and ME. Activities of serum AST, ALT and contents of liver TBARS were tended to be increased with high cholesterol diet and reduced by C. tora ethanol extract supplementation but had not significance. These results suggest that C. tora ethanol extract may exert a lipid lowering effect in serum and liver of rats.

  • The prevalence of obesity is increasing worldwide, and since obesity is associated with dietary factors and sedentary lifestyles, it is a disease that is readily developing in the modern population. Because obesity is accompanied by serious complications such as diabetes and cardiovascular disease, prevention and treatment are important. Currently, drugs such as liraglutide and phentermine are used to treat obesity by suppressing appetite and inducing gastrointestinal motility delay. However, various side effects may occur, including thyroid cancer, cardiovascular problems, and central nervous system disorders. Therefore, to explore an obesity treatment method with relatively few side effects, a method known as "fat browning" was introduced to change white adipose tissue into brown adipose tissue to increase energy consumption. Ongoing studies are attempting to find effective natural substances to safely induce browning. Many natural substances have been identified. The induction of browning by treatment with natural substances generally involves three mechanisms: positive control of browning-inducing factors, inhibition of differentiation into white adipose tissue, and the activation of mechanisms related to browning. In this study, we describe plant extracts with known browning-inducing effects, such as strawberry, black raspberry, cinnamomum cassia, and Ecklonia stolonifera extracts. We also summarize the underlying mechanisms of action identified thus far, including the signaling pathway mediated by these extracts to induce browning. Furthermore, the effects of brown adipose tissue generated through browning on heart disease as an endocrine organ disruptor are discussed.

  • Objectives: This study evaluated smear layer removal by different chemical solutions used with or without ultrasonic activation after post preparation. Materials and Methods: Forty-five extracted uniradicular human mandibular premolars with single canals were treated endodontically. The cervical and middle thirds of the fillings were then removed, and the specimens were divided into 9 groups: G1, saline solution (NaCl); G2, 2.5% sodium hypochlorite (NaOCl); G3, 2% chlorhexidine (CHX); G4, 11.5% polyacrylic acid (PAA); G5, 17% ethylenediaminetetraacetic acid (EDTA). For the groups 6, 7, 8, and 9, the same solutions used in the groups 2, 3, 4, and 5 were used, respectively, but activated with ultrasonic activation. Afterwards, the roots were analyzed by a score considering the images obtained from a scanning electron microscope. Results: EDTA achieved the best performance compared with the other solutions evaluated regardless of the irrigation method (p < 0.05). Conclusions: Ultrasonic activation did not significantly influence smear layer removal.
