This study examined the effect of self-perception of health and related factors of flood life and disease on health floods intakes among the middle aged(150 men and 159 women) in the Jeonbuk region. The health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), nutritional supplements(NS), and other manufactured health foods supplements(MHFS). Differences of BMI and self-perception for body shape was that overweight was 30% in men and 24.5% in women on BMI, but conversely was 21.3% in men and 43.4% in women on self-perception for body shape. Men thought themselves more than normal weight, but women thought themselves less than normal weight for the criteria of normal weight. Consumption of CM was high in the overweight group on BMI and was a low in the overweight group on self-perception for bodyshape Men thought themselves better than women and those in their 40's thought better than those in their 50's on self perception of health status, and women were better than men on self-perception of food habits. The difference of health foods intakes according to the self-perception of health status and food habits was not significant. The points of food habits, food attitude and nutrition knowledge were 11.21 $\pm$ 2.43, 68.18 $\pm$ 15.56 and 15.53 $\pm$ 1.59 in women and 10.49 $\pm$ 2.71, 67.53 $\pm$ 14.41, and 15.11 $\pm$ 1.79 in men respectively. The points of all were higher for women than for men. Consumption of CM (p < 0.01) and TF(p < 0.01) were a low in groups that scored high points on nutrition knowledge. The points of climacteric symptoms were that men were 48.36 $\pm$ 6.30 and woman were 46.43 $\pm$ 6.70. Men thought themselves in good condition more than women(p < 0.01), and those in their 40's thought themselves in good condition as opposed to those in their 50's in men(p < 0.05). Consumption of TF and NS were high in the low points group on climacteric symptoms(p < 0.01). Women were higher than men on morbidity, but men were more than women on cases of liver disease(p < 0.01). Consumption of CM was high in the liver disease group(p < 0.05), MHFS was high in the kidney disease group(p < 0.05), TF and NS were hgih in the bone disease group(p < 0.05) and NS was hgih in the endocrine disease group(p < 0.05). People in their 40's were higher than those in their 50's in men on morbidity of cold(p < 0.05), women were higher than men by about 2 times on constipation (p < 0.01), those in their 40's were higher than those in their 50's in mein on gastritis(p < 0.05). Consumption of NS was highest for those with diseases in respiratory organs and gastrointestinal tracts. This study suggests that nutritional education for the right recognition of self-perception of health status and food habits, and nutrition knowledge are needed to select for health floods. Consumption of health foods was different according to kinds of diseases. Thus, recognition of etiology, symptoms and dietetics of diseases is needed to select adequate health foods for diseases in middle age.

Effect of Streptococcus faecium(SF) and an antibiotic, Colistin(Col), supplemented to diets singly or in combination, on the performances and changes of intestinal population of microflora of broiler chicks studied. A total of 252, day-old chicks(Arbor Acre) of mixed sex(M：F＝1：1) were alloted into six groups. A diet with no Col and SF was referred as a control diet. The basal diets were added with two levels of SF, 0.04 and 0.08%, singly or in combination with Col 10ppm Another diet was prepared by adding only Col 10 ppm. Numbers of the microorganism in diets added with SF 0.04% and 0.08% were 7$\times$10$^{4}$ and 1.4$\times$10$^{5}$ /g diet respectively The diets consisting of corn and soybean meal as major ingredients were fed for a period of seven weeks . During the feeding trial, fresh excreta were sampled at the end of every week in a sterilized condition to count microbial changes from each dietary group. Microbial changes of large intestine were also measured from nine birds sacrificed at the end of the 4th and 7th weeks each time per dietary group. Excreta from all the groups were also collected quantitatively at the end of 3rd and 6th weeks to measure digestibility of the diets, At the end of 7th week, nine birds from each group were also sacrificed to measure weight changes of gastrointestinal tracts . Average body weight gains of broilers fed the diets added with SF 0.08% (2.37kg) or SF 0. 08%+col 10ppm(2.34kg) were significantly larger than that of the control(2.18kg). The weight gains of the other groups were not statistically different from that of the control Feed/gain ratios of the supplemental groups were better than that of control (P＜0.05) except that of birds fed the diet added only with SF 0.04%. Digestibilities of nutrients such as dry matter, crude protein, crude fat and total carbohydrates were not altered by the consumption of the diets added with SF and/or Col throughout the whole feeding period. As expected, the numbers of Streptococci in the excreta from birds fed diets added with SF increased significantly with a statistical difference between groups with SF 0.04% and SF 0.08% most of the time. However. addition of Colistin to the diets supplemented with SF did not give any effects on the number of the microorganism. Numbers of coliforms in the excreta were apparently reduced by feeding the diets added with SF and/or Col(P＜0.05). There were, however, no additive effects observed between the two feed additives in this regard when supplementing Col to the SF diets. Distributions of intestinal microflora exhibited exactly the same pattern as those of the excreta. Length of small intestine of the birds fed diets added with SF 0.08% with or without Col 10 ppm became significantly longer with a range of about 10% than those of the birds fed diets without SF. However, the empty weight of the small inestine of the former group was lighter than that of control These changes resulted in a significant reduction in weight/unit length of the intestine of the birds fed diets supplemented with Col and SF singly or in combination. In overall conclusion, diet added with SF 0.08% appeared most effective in improving broiler performances. Colistin added at a level of 10ppm was not beneficial at all in itself or in combination with SF in terms of broiler performances or changes of intestinal microflora population. The efficacy of SF and Col could be attributed to the changes of wall thickness of the small intestine.
