This salt was synthesized by sulfonating 1-methyl tetradecanoic acid derived from palm oil and coconut oil with sulfur trioxide. The tests were attempted in accordance with the OECD (Organization for Economic Cooperation and Development) Guidelines for the Testing of Chemicals. The 72 h ErC<sub>50</sub> exceeded 100 mg/L in the alga growth inhibition test. In the daphnia acute immobilization and reproduction tests, 17.2 mg/L of 48 h EC<sub>50</sub> and 4.10 mg/L of NOEC were derived, respectively. These ecotoxicities of C14MES were equivalent to or lower than that of other similar anionic surfactants, such as LAS (linear alkylbenzene sulfonate) or AOS (alpha olefin sulfonate).<br>

The aquatic risk of 2-sulfonato fatty acid methyl ester sodium salt (MES) used in household detergents was assessed. The environmental exposure assessment expressed as predicted environmental concentration (PEC) was determined on the basis of monitoring results from the seven sites of four rivers in the urban area in Tokyo and Osaka. The 95 percentile as well as geometric mean of the MES concentration was found to exhibit a good correlation with the geometric mean of the Biochemical Oxygen Demand (BOD; the latter's regression was grater than 0.99). The predicted no effect concentration (PNEC) for the aquatic environment was estimated by performing chronic assays of algae and daphnia. The risk characterization ratio (RCR: PEC/PNEC) was less than 1. Therefore, it is concluded that MES will not adversely affect the aquatic environment in Japan.<br>

The effect of consumption of fatty acids and selected nutrients, along with regular physical activity, on cardiovascular risk factors in rats was investigated.Male rats were divided into the seven groups: Group 1: regular food and drinking water, Group 2: same as Group. 1 + physical activity (whole body vibration; WBV), Group 3: same as Group. 2 + calcium, vitamin D, boron, Group 4: same as Group. 3 + canola oil, Group 5: same as Group. 3 + sunflower oil, Group 6: same as Group. 3 + mix of sunflower oil and canola oil, Group 7: same as Group. 3 + coconut oil. Rats were treated for 8 weeks, and analysis of the frozen plasmas was performed. A- Analysis between the treatment groups and control revealed that vibration training in Group 2 increased body weight (P = 0.04), plasma creatin kinase (CK), (P = 0.02), and estradiol (E2), (P = 0.03). Rats in Group 5 consumed less food and plasma levels of cholesterol and LDL-cholesterol (LDL-C) increased significantly (P = 0.02) in Group 6 and in Group 7 (p

A novel method to quantify glycidol fatty acid esters (GEs), supposed to present as food processing contaminants in edible oils, has been developed in combination with double solid-phase extractions (SPEs) and LC-MS measurements. The analytes were five species of synthetic GEs: glycidol palmitic, stearic, oleic, linoleic and linolenic acid esters. The use of selected ion monitoring in a positive ion mode of atmospheric chemical ionization-MS with a reversed-phase gradient LC provided a limit of quantification of 0.0045-0.012 μg/mL for the standard GEs, which enables the detection of GEs in μg ranges per gram of edible oil. Using the double SPE procedure first in reversed-phase and then in normal-phase second, allowed large amounts of co-existing acylglycerols in the oils to be removed, which improved the robustness and stability of the method in sequential runs of LC-MS measurements. When the method was used to quantify GEs in three commercial sources of edible oils, the recovery% ranged from 71.3 to 94.6% (average 79.4%) with a relative standard deviation of 2.9-12.1% for the two oils containing triacylglycerols as major components, and ranged from 90.8 to 105.1% (average 97.2%) with a relative standard deviation of 2.1-12.0% for the other, diacylglycerol-rich oil. Although the accuracy and precision of the method may not be yet sufficient, it is useful for determining trace levels of GEs and will be helpful for the quality control of edible oils.

Examination was made of the effects of tea catechins (TC) on diet-induced obesity. Exposure to high-fat-diet (30% fat) in C57BL/6J mice for 4 weeks induced significant increase in body weight, visceral fat (epididymal, mesenteric, retroperitoneal, perinephric) weight and plasma concentrations of glucose, triacylglycerol and leptin, compared to low-fat diet (5% fat). Treatment with 0.1%TC (high-fat diet +0.1%TC group) had little effect on diet-induced obesity. Relative to high-fat diet and 0.1%TC treatment, 0.5%TC treatment (high-fat diet +0.5%TC group) was noted to bring about significant decrease in body weight, visceral, fat weights and plasma leptin. Lipid absorption rate was the same with the high fat diet and 0.5%TC treatment. An oral soluble starch and sucrose (SS-S) tolerance test was conducted on C57BL/6J mice to evaluate the effects of TC to sugar absorption. When the ratio of TC to sum of SS-S was the same as that in the diet composition for the 0.5%TC treatment, the plasma glucose level showed no response. These results demonstrate for the first time TC to have antiobesity effects on diet-induced obesity in mice, and suggest these effects to be exerted through a mechanism that would not involve inhibition of intestinal absorption of sugar and lipid.

The body fat reducing effect of tea catechins was previously confirmed in humans. The effects of tea catechins for reducing body fat were thus studied as basis for actual application. Three experiments on healthy male adults (n=82) were conducted to determine the effects of long-term tea catechins administration on body fat and biochemical blood parameters. First experiment: tea catechins were given as oolong tea-like beverage for 12 weeks. In 600 and 900 mg groups, visceral fat was significantly loss than in the control (600 mg group p=0.0317, 900 mg group p=0.0098). The effects were more pronounced at greater of tea catechins administration. No significant changes in biochemical blood parameters including fat-soluble vitamins were detected. Second experiment : oolong tea-like beverage containing tea catechins at nearly same amounts on in the 600 mg group was given for 20 weeks. Abdominal fat, including visceral fat, was significantly loss than in the control (total fat area p<0.0001, visceral fat area p=0.0004, subcutaneous fat area p=0.0001). Plasma PAI-1 was also significantly decreased (p=0.0080). Third experiment : green tea-like (GT group) and oolong tea-like (OT group) beverages containing approximately 540 mg tea catechins were given for 12 weeks. In the two groups, visceral fat was significantly loss than in the control (GT group p=0.0284, OT group p=0.0095) and the effects of two beverages were similar. Long-term tea catechins administration at 500 to 600 mg/day in humans would thus appear to reduce body fat without influencing fat-soluble vitamins, of which the absorption may be inhibited, and various serum and plasma indices regardless of the kind of beverages.

We evaluated the allergen inactivating effect of colloidal silica by performing enzyme-liked immunosorbent assay (ELISA) whose wells were coated with 150 ng/mL of Japanese cedar pollen allergen (Cry j 1) or mite allergen (Der f 2). The allergens were almost 100% inactivated by 100 μg/mL of colloidal silica having a particle size 5 nm, and the inactivating effect was increased by aluminum binding to the surface of the colloidal silica. The results show that colloidal silica is a promising material for allergen inactivation. Since colloidal silica forms an insoluble nondispersive solid when dried, it is expected that airborne allergens can be reduced by binding them to colloidal silica.
