As diverse physiological functions of taurine have been reported, taurine-containing health drinks and products are marketed worldwide for the treatment of various conditions such as improvements of liver, heart and circulatory functions or as an aid to athletic performance. Although animal studies have shown that taurine is fairly safe when supplemented in the diet for an extended period, the effective dose range of taurine for dietary supplements is in controversy. Reports on dietary taurine intakes have been sparse, and would serve as a guideline for determining an appropriate taurine dosage. The present study was aimed to estimate dietary intake level of taurine using the taurine content database of commonly used food stuffs established recently in our laboratory, and also to evaluate plasma concentration and urinary excretion of taurine in adolescents and adults residing in Seoul area. Dietary taurine intakes of the subjects were 219$\pm$16.9mg/day for 16-19 years old(n=123), 177$\pm$18.1mg/day for adults older than 20 years old(n=123). Male subjects(n=115) consumed 216$\pm$21.1mg of taurine/day, while female subjects(n=131) consumed 181$\pm$14.3mg of taurine/day(p<0.05). The level of dietary taurine intake was positively correlated with the levels of dietary intakes of energy, carbohydrate, total lipids, cholesterol, vitamin A, vitamin B$_1$, niacin, vitamin C, calcium, phosphorous, sodium and potassium at p<0.01, and with dietary intakes of iron and animal lipids at p<0.05, respectively. Plasma taurine concentration of subjects were 135$\pm$5.9$\mu$mol/L, which is considered to be within a normal range for healthy subjects. The subjects excreted 1158$\pm$72.7nmol/ of tarine mg creatinine in their urine, which is approximated as 150-170mg of taurine/24hr urine based on the assumption that 18mg creatinine/kg/day is excreted in the urine of healthy adults, and this would be about 80% of the daily taurine intake observed in the same subjects. Dietary taurine intake level was positively correlated with plasma taurine concentration, as well as with urinary taurine excretion corrected by creatinine excretion at p<0.05. The present study was the first report of taurine intake, and plasma concentration and urinary excretion of taurine in a Korean population so far, and these results would serve as an index for the future study evaluating taurine status in a diverse population within and outside Korea.

The purpose of this study was to investigate dietary taurine intakes, plasma taurine levels and urinary taurine excretions of women in Seoul(Kangbuk-ku) and Kyunggi(Yeoju) area, Korea. Seventy married women aged 39.7$\pm$8.9 have volunteered for this study: 36 from Seoul area and 34 from Kyunggi area. Diet samples were collected from the participants and the samples included three meals (breakfast, lunch and supper), snacks, drinks and whatever the participants had eaten for 24 hours. The plasma was obtained by allowing a 5 $m\ell$ fasting blood sample to be in a heparinized tube for 30 min and centrifuging it at 11,000${\times}$g for 20 min. The collected diets were blended, centrifuged and deproteinized. Taurine levels in the diet and plasma were determined as the dabsyl derivative using HPLC with Rf-detector. The intake of taurine ranged from 6.8 to 837.8 mg/day and its mean value was l45.5$\pm$164.0 mg/day (mean$\pm$SD). The 90th, 50th and 10th percentile values of the taurine intake were 280.0, 94.3 and 26.8 mg/day, respectively. There was a significant difference between two groups: 202.0$\pm$204.9 for Seoul area and 85.5$\pm$67.2 mg/day for Kyunggi area(p<0.00l). The taurine level in plasma ranged from 42.1 to 201.9 $\mu$mol/L and its mean value was 74.9$\pm$22.8 $\mu$mol/L. The 90th, 50th and 10th percentile values of the plasma taurine were 101.1, 70.7 and 54.6 $\mu$mol/L, respectively. There was no significant difference between Seoul area and Kyunggi area in plasma taurine level.

The purpose of this study was to determine the effects of taurine supplementation and taurine depletion on blood glucose and blood lipid concentrations in insulin-treated diabetic rats. Four groups of Sprague-Dawley male rats were fed the purified diet for 3 weeks ; nontaurine-supplemented diabetic rats(E0), nontaurine-supplemented diabetic rats with insulin treatment(E0＋I), 1% taurine-supplemented diabetic rats with insulin treatment(E1＋I) and taurine-depleted diabetic rats with insulin treatment(EA＋I). Diabetes was induced by streptozotocin injection(50mg/kg B.W.). Isophane insulin was given subcutaneously into the abdominal wall of the diabetic rats(4 unit/rat/day). E1＋I were supplemented with 1% taurine in drinking water. To induce taurine depletion, EA＋I were treated with 5% $\beta$-alanine in drinking water. E1＋I had significantly higher body weight compared to that of E0. The food intakes of E1＋I and E0＋I were significantly decreased compared to that of E0. There was no sigfniciant difference in food intake between E1＋I and E0＋I. The water intake of rats was significantly different among the groups ; E0>E0＋I>E1＋I>EA＋I. The urine volume of E0 was significantly increased compared to those of insulin-treated goups. The blood glucose concentration of E0 was significantly increased compared to those of insulin-treated groups. In the oral glucose tolerance test(OGTT), E0＋I and E1＋I had significantly lower blood blucose concentrations compared to E0 after 30 min. Also EA＋I had significantly lower bloodglucose concentrtion compared to E0 and E0＋I. The plasma total cholesterol and LDL-cholesterol concentratons of EA＋I were significantly incrased compared to those of other groups. Therefore, it may be suggested that tuarine supplementation is useful for insulin-dependent diabetes in order to prevent diabetic complications suchas cardiac vascular diseases.

Awamori is produced by fermenting steamed indica rice. Awamori-pressed lees is a by-product of the Awamori production process. Tofu lees is a by-product of the Tofu production process. Research was conducted to test if dried Awamori-pressed lees and Tofu lees can be used as a mixed feed ingredient for raising male goats. Eighteen male kids were divided into three groups of six animals (control feed group (CFG), Awamori-pressed lees mixed feed group (AMFG), Tofu lees mixed feed group (TMFG)). The CFG used feed containing 20% soybean meal as the main protein source, while the AMFG and TMFG used feed mixed with 20% dried Awamori-pressed lees or dried Tofu lees. The groups were fed mixed feed (volume to provide 100 g/d increase in body weight) and alfalfa hay cubes (2.0 kg/d) twice a day (10:00, 16:00). Klein grass hay and water was given ad libitum. Hay intake was measured at 10:00 and 16:00. Body weight and size measurements were taken once a month. At the end of the experiment, a blood sample was drawn from the jugular vein of each animal and the carcass characteristics, the physical and chemical characteristics of loin were analyzed. DCP and TDN intakes in AMFG and TMFG showed no significant difference to the CFG. Cumulative measurements of growth in body weight and size over the 10 mo period in the AMFG and TMFG were similar to the CFG. Blood parameter values were similar to those in normal goats. Dressing carcass weight and percentages, and total weight of meat in the AMFG were similar to that in the CFG, but smaller in the TMFG. The compressed meat juice ratio was higher in both the TMFG and AMFG than the CFG. While the fat in corn, Awamori-pressed lees, and Tofu lees contains more than 50% linoleic acid, the loin fat in both the AMFG and TMFG was very low in linoleic acid due to the increase in the content of oleic acid, stearic acid, and palmitic acid. This indicates that feeding on AMF and TMF does not inhibit hydrogenation by ruminal microorganisms. As in the CFG, the total essential and non-essential amino acids in the loin of the AMFG and TMFG were well balanced. Compared to the CFG, the AMFG and TMFG were high in taurine and carnosine. The results indicate dried Awamori-pressed lees and Tofu lees can be used as a feed ingredient for raising male goats.
