Background: The flexible flatfoot is characterized by a flattening of the foot arch due to excessive bodyweight. The use of shoe insoles or taping methods has been identified as effective in realigning the navicular or calcaneus bones and addressing supination in pronated feet. Objects: This study aimed to analyze the difference between the arch taping attachment method, introduced in a previous study, and a novel taping method designed to provide support to the inner aspect of the heel bone in cases of flexible flatfoot. Methods: A navicular drop test was performed to discriminate flexible flatfoot. To analyze the differences in pressure distribution during walking for each taping method, the subjects underwent testing in the barefoot state with no attachments. The procedure included a sequence of arch taping and heel taping. Subsequent analysis of pressure distribution during walking utilized the GaitRite^® system (GAITRite Gold, CIR Systems Inc.). Results: Arch taping and calcaneus taping significantly reduced the integrated pressure over time and peak pressure on the medial side of the midfoot for both feet compared to the barefoot state. Conclusion: The findings of this study suggest that supporting the inside of the heel through calcaneus taping, without direct stimulation to the longitudinal arch and navicular bone, is an effective intervention for flexible flatfoot.

The influence of fermented red ginseng (FRG) and red ginseng extract (RGE) on the growth, nutrient digestibility, and meat quality of growing-fattening pigs was evaluated in the present study. In total, 120 growing-fattening crossbred pigs with a bodyweight of 21.77 kg (_SE1.88) were allocated to 3 treatments with 8 repeats of 5 pigs (2 boars and 3 gilts) for a 22-week experimental period. The pigs were supplemented with a basal diet (CON group) or a basal diet containing 0.1% FRG or 0.1% RGE. Pigs fed the FRG diet had a higher (p < 0.05) average daily gain (ADG) from days 1 to 42 and during the whole period. The apparent nutrient digestibility of dry matter (DM) and nitrogen (N) was improved (p < 0.05) in the FRG treatment in week 6 and that of DM in week 10. Moreover, the drip loss of the meat from the FRG pigs was reduced (p < 0.05) on days 1, 5, 7, and 9. Taken together, this study revealed that the supplementation of 0.1% FRG in the diet improved the ADG and the apparent nutrient digestibility of DM and N and decreased the drip loss of the meat. However, the addition of RGE did not affect the growth of the growing-fattening pigs.

Two growth performance experiments were undertaken in order to compare the nutritional benefit of micronized dehulled barley (MDB) with wheat and maize. In the first experiment, ninety-six 24 d old Cotswold pigs with an average body weight of 9.5 kg were randomly allotted into one of four dietary treatments. The wheat and MDB ratio in the four complex diets were 100% wheat, 75% wheat+25% MDB, 50% wheat+50% MDB and 100% MDB; cereal was about 47% of the whole diet and varied by using different ratios of wheat and MDB. Starter phase was started at a bodyweight 9.9 kg; grower phase continued at liveweight 37.1 kg and finished at 74.0 kg. The ADFI, ADG and feed efficiency (F/G) were not affected (p>0.05) by the level of MDB in the diet from 9.9 to 37.1 kg live weight. However, ADFI was (p<0.05) less (14%) for the pigs fed the 75 or 100% of MDB based diets without affecting F/G during the second phase (37.1 to 74.0 kg live weight). Pigs fed the MDB based diet had a lower (p<0.05) plasma urea nitrogen (PUN) concentration than the pigs fed the wheat-based diet. In the second experiment, the trial started at 9.9 kg body weight and ended at market weight (107.6 kg), with three different phases in the trial. One hundred and twenty Cotswold pigs were randomly assigned to one of three dietary treatments. The maize and MDB ratio in the three diets were 100% maize, 50% maize+50% MDB and 100% MDB. Diet treatments did not affect (p>0.05) growth performance, PUN level, carcass characteristics and organ size, except for an improvement (p<0.05) in ADG for the pigs in the starter phase fed 50% and 100% MDB based diets.

An experiment was conducted to increase the quality of rice bran by fermentation using Bacillus amyloliquefaciens and humic substances and its utilization as a feed ingredient for broiler chickens. The experiment was carried out in two steps. First, the fermentation process was done using a completely randomized design in factorial with 16 treatments: i) Dosage of B.amyloliquefaciens ($2.10^8cfu/g$), 10 and 20 g/kg; ii) Graded levels of humic substances, 0, 100, 200, and 400 ppm; iii) Length of fermentation, three and five days. The results showed that the fermentation significantly (p<0.05) reduced crude fiber content. The recommended conditions for fermentation of rice bran: 20 g/kg dosage of inoculums B. amyloliquefaciens, 100 ppm level of humic substances and three days fermentation period. The second step was a feeding trial to evaluate the fermented rice bran (FRB) as a feed ingredient for broiler chickens. Three hundred and seventy-five one-day-old broiler chicks were randomly assigned into five treatment diets. Arrangement of the diets as follows: 0%, 5%, 10%, 15%, and 20% level of FRB and the diets formulation based on equal amounts of energy and protein. The results showed that 15% inclusion of FRB in the diet provided the best bodyweight gain and feed conversion ratio (FCR) values. In conclusion, the nutrient content of rice bran improved after fermentation and the utilization of FRB as a feed ingredient for broiler chickens could be included up to 15% of the broiler diet.

The purpose of this study was to confirm that regular physical exercise habit and calcium intake play a role reducing the risk of cardiovascular diseae, particularly to confrim that regular exercise is important in reducing serum lipid levels. Subjects were classified into regular exercise group(more than 3 times/wk, more than 30 min per exercise) and non-regular exercise group. A convenient frequency method was used to assess the nutritional intake of subjects. Anthropometric measurement such as bodyweight and hight, and blood pressure were measured. There was no significant difference between nonexercisers and exerciser in energy intake, calcium intake and blood lipid levels. The strength of frequency of exercise may not by adequate to modify lipid profiles in premenopausal woman with normal lipid level, Although we found no significant difference in blood lipid levels, this result does not imply there are no benefits of exercise subjects. There were no signigicant correlations between age or weight with blood lipids in regular exercise group, while there were significant positive correlations between age of weight with blood lipids in non-regular exercise group. The levels of serum cholesterol, and triglyceride, blood pressure and atherogenic index increased with age in nonexercise women, Especially, atherogenic index was lower in regular exercise group. The blood pressure in nonexercise group was significantly higher than that in regular exercise group There was a highly significant negative correlation between calcium intake and blood pressure in nonexercise women, There was a highly significant negative correlation between calcium intake and blood pressure in nonexercise women. The results suggest that increased habitual physical activity and calcium intake may have desirable effects on serum lipid levels and blood pressure in premenopausal women.(Korean J Nutrition 34(1):62-68, 2001)

The use of the dairy male calf for beef production has been found to be economically unprofitable during the past due to high cost of feeds and relatively low beef price. However, due to current shortage of domestic beef supply and rising beef price, this research aimed to assess feeding methods and costs and returns in raising dairy male calves for beef production under changing economic conditions. Two diets were compared: calves on an optimal feeding level were given milk replacer for 44 d and a concentrate (with ad lib. hay) to 150 kg bodyweight that contained 16% crude protein; those given a sub-optimal diet, more appropriate for smallholder farms, received milk replacer for 30 d and 14% CP concentrate. Twelve pairs of dairy male calves (average age 32 days) of Holstein-Friesian high grades were used, each pair having similar influencing factors such as weight, age, and genotype. Each animal was kept in a separate feeding stall until reaching the final weight of 150 kg. The results from this experiment showed that the differences of traits concerning growth performance and feed efficiency of the animals raised under the two feeding regimes were statistically nonsignificant. The optimal group was just slightly better, but the cost of production of the sub-optimal group was 24 percent lower (4,667 vs. 6,144 baht per animal) and the cost difference was highly significant. The results from this investigation showed that beef production from dairy male calves can be economically viable when sub-optimal feeding method is used and market beef price is at current level.

The objective of this study was to determine the levels of nutritionally related blood metabolites, age and body weight at puberty in gilts fed on corn cob-based diet in Mukota and Landrace${\times}$Mukota crossbred gilts. Ten gilts of each of Mukota and crossbred genotypes were fed two diets for 14 weeks in a 2${\times}$2 (breed${\times}$diet) factorial treatment arrangement. A corn-cob based diet, designed to contain 2,304 kcal ME/kg, and a standard pig grower diet, were used. The corn cob constituted 20 percent of the total ration. Fortnightly, bodyweights and feed conversion ratios (FCR) were recorded. Blood samples were collected to determine blood glucose, urea and creatinine levels. The average daily bodyweight gain (ADG) in the Mukota was lower (p<0.05) than in the crossbred gilts. Crossbred gilts fed on the corn cob-based diet had lower (p<0.05) urea values from eight weeks from the start of the experiment (p<0.05) compared to Mukota gilts fed the same diet. There were no differences in blood glucose and creatinine concentrations between diets and genotypes. The lack of differences in the nutritionally-related blood metabolites suggest that corn cobs could be incorporated at 20 percent inclusion without compromising blood metabolite concentrations and age at puberty of the Mukota and Landrace${\times}$Mukota gilts.

The possible effects of 10% carbohydrate containting diets on the serum glucose and lipids values were studied with normal and alloxan - diabetic male rats for a period of 28 days. The diets were supplemented with either glucose, cornstarch or sucrose, fructose or the basal diet containing no added carbohy drates. After this period, 3 to 4 rats among the each group were killed and samples of serum, liver, spleen and kidney were collected. The others were rendered diabetic by the intraperitoneal injection of alloxan ($190mg/\frac{wt}{kg}$). Then original feeding scedule was continued for 3 days in all five diabetic groups, before the collection of tissue samples and serum. Feeding the nondiabetic rats with glucose and fructose delayed the bodyweight development relatively compared with nonsugar group. The weight deductions after alloxan injection were similar in all feeding groups. All diabetic animals exhibited increased blood glucose triglceride levels but almost unchanged total cholesterol values. Blood glucose values for nondiabetic rats were normal ranges, and then glucose feeding group was the highest. Total - cholesterol values were the highest in nondiabetic rats fed glucose, fructose and in diabetics fed sucrose, glucose. Triglyceride values were the highest in nondiabetic rats fed sucrose, and no difference in diabetic rats. Some cornstarch group exhibited fatty-livers in diabetic and nondiabetic, and more studies need.

Objective: Leejung-tang (Rechu-to in Japanese) is a traditional Korean herbal formula used for treatment of gastrointestinal disorders such as vomiting, stomach pain, chronic gastritis and gastrointestinal ulceration. The present study was carried out to investigate the potential acute toxicity of Leejung-tang water extract (LJT) by a single oral dose in Crl:CD (SD) rats in compliance with current guidelines. Methods: In the preliminary study, there were no adverse effects such as death, clinical signs, and body weight changes at dose levels of 500, 1000, and 2000 mg/kg/day body weight. Based on the results, a dose of 2000 mg/kg was selected as the toxicological limited dose. LJT was administered once by gavage to male and female rats at dose levels of 0 and 2000 mg/kg bodyweight. During the study period, mortalities, clinical findings, and body weight changes were observed for 14 days following the administration. On day 14 after the treatment, the animals were sacrificed by carbon dioxide overdose and complete gross postmortem examinations were performed. Results: In present study, no treatment-related deaths were observed. There were no adverse effects on clinical signs and body weight changes. In addition, there were no observed gross findings in all groups except for a kidney cyst in the 2000 mg/kg/day female group. Conclusion: The results indicated that LJT did not induce toxic effects at a dose level up to 2000 mg/kg in rats and its median lethal dose ($LD_{50}$) was considered to be over 2000 mg/kg/day body weight for both genders.
