The objective of this study was conducted to investigate growth and development status of infants fed soy-based formulas over 3 months. The height and weight were measured and Z-scores were calculated by using standard of the same age groups. Their mothers were interviewed using questionnaires including general and environmental characteristics, total food intakes, soy based formula intakes and Ewha infant development screening test. Main results were as follows: 1) Nutrient intake levels of subjects were similar to or more than the level of Korean Recommended Dietary Allowances except for intakes of vitamin E (79.89% RDA), and the average status of nutrient intakes of infants were fairly good. 2) Z-scores of height for age (HAZ) and Z-scores of weight for age (WAZ), Kaup index, WLI and Ewha Infant Developmental Screening Test score of subjects were in the normal growth range. 3) There were no significant differences among soy based formula intake percentile groups in HAZ, WAZ, Kaup index, WLI and Ewha Infant Developmental Screening Test score. 4) Total energy intake was positively correlated with HAZ (p < 0.00, WAZ (p <0.00, and WLI (p < 0.05) in infants less than 12 month. Also, soy based formula energy intake was positively correlated with HAZ (p < 0.05) in infants less than 12 month. However, energy and soy based formula intake levels of infants over 12 month were not significant among variables. Considering results of this study, infants fed soy-based formulas over 3 months showed normal growth and development status. Further studies are needed to evaluate longterm growth and development in infants fed soy based formulas.

Special formulas are those in which one of the basic nutrients (usually the protein and/or carrbohydrate) has been changed to an alternative nutrient that an individual baby may better tolerate. The following are specialized formulas : Soy formulas, hypoallergenic formulas, Lactose free formulas, Premature baby formulas, Low phosphate formulas, Formulas for inborn errors of metabolism. Less is known about the long-term effects of feeding babies these special formulas and each formula has its unique properties and indications. The pediatrician must acquaint themselves with all commercially available infant formulas so as to provide the parent with reliable and unbiased information about them.

Infant formula in nursing bottle, with inappropriate feeding habits, is major factor associated with the development of nursing caries. Although each infant formula has different carbohydrate and protein composition, studies comparing cariogenic potential of many Korean-branded infant formulas are deficient. In addition, it is on the point of being difficult to evaluate the cariogenecity of milk due to development of many infant formulas. In this study, to evaluate the cariogenic potential of many infant formulas, after oral rinse with six Korean-branded infant formulas(three milk based formulas, one soy based formula and two specific formulas for infants with allergy to milk protein and with lactose intolerance) for ten adult volunteers(eight males and two females), plaque pH change was measured with In vivo/In vitro combination technique and results were as follows. 1. All six different kinds of Korean-branded commercial infant formulas dropped the plaque pH significantly(p<0.05) and at an hour after rinse, plaque pH was not recovered in most of subjects. 2. Soy based infant formula and casein-hydrolyzated infant formula containing no casein dropped the plaque pH significantly more than milk based infant formula containing casein (p<0.05). 3. In the milk protein of infant formulas, casein had more effect on buffering the pH change of the infant formula than whey protein and casein-hydrolyzated infant formula had a reduced effect of casein. 4. In infant formulas with similar protein composition, infant formula containing sucrose dropped plaque pH more than infant formula containing lactose, but there was no significant difference (p>0.05).

대두 단백 제조유는 우유에 대해 알레르기를 일으키는 소아들에게 우유 알레르기를 치료하며 아토피의 예방을 위해 대체식품으로 1929년이래 사용되어 왔다. 그러나 대두 단백 제조유는 알레르기 반응을 유발시킬 수 있어서 이의 효용성에 대해서는 아직도 많은 논란이 지속되고 있다. 우리나라 식품 알레르기 환아에 대한 상황파악은 유럽이나 미국과 비교해 볼 때 아직도 잘 이루어지고 있지 않다. 본 연구의 목적은 국내 소아들의 우유 알레르기와 상관하여 대두 알레르기 발생 빈도 조사에 있다. 본 연구에서 임상적 증상을 나타내는 153명의 환아들 중에서 대두 또는 우유 단백질에 알레르기를 일으키는 환자가 각각 21% 또는 51.6%로 나타났다. 그리고 22명(14%)의 환아들은 우유와 대두 두가지 단백질에 모두 알레르기 증상을 나타내었다. 우유알레르기 환자의 경우는 27.8%의 소수 환아가 대두단백질에 알레르기 반응을 보여 주었으나, 대두 알레르기 환자는 대부분(68.8%)이 우유에 대한 알레르기 반응을 나타내는 것으로 확인되었다.

To evaluate the effect of feeding methods on growth and zinc nutritional status of infants early in life, we monitored from birth to 36 months in 51 infants who were exclusively fed human milk (HM, n=20), casein-based formula (CBF, n=12), or soy-based formula (SBF, n=19) during the first five months of life. Zinc status was assessed by analyzing serum zinc concentrations and zinc intakes. Zinc contents in HM and formulas were measured. Zinc intake was estimated by weighing infants before and after feeding in the HM group and by collecting formula-intake records in the CBF and SBF groups. After solid foods were introduced, all foods consumed were also included to estimate zinc intake. The growth of infants in all groups was similar to that established for normal Korean infants. Human milk zinc concentrations declined as lactation progressed. Zinc concentrations in all formulas tested in this study were higher than HM and were also higher than those claimed by the manufacturers. During the first twelve months, mean serum zinc concentrations of infants were similar in all groups, although infants in the HM group consistently had the lowest zinc intake among the groups, and the overall zinc intake in infants fed SBF was highest. This finding could be explained by the difference zinc bioavailability of HM and formulas. In conclusion, infants fed HM, CBF or SBF has normal growth up to three years of age, although HM contained the lowest zinc concentration followed by CBF, then SBF.

Selenium contents of infant formulas that were commerically available in Japan and Korean were determined by the method of atomic absorption spectrometry with hydrode generation. Total means of selenium contents were 45.2$\pm$22.1ng/g(n=34) in all the Japaneses formulas and 58.3$\pm$18.9ng/g(n=22) in all the Korean formulas. selecnium contents of milk-based formulas (54.7$\pm$23.2ng/g in Japan, n=20 and 64.8$\pm$12.6ng/g in Korean , n=18) were significantly higher than those of soy-based formulas (36.8$\pm$11.0ng/g in Japanes brands, n=11 and 36.4ng/g in Korean one , N=1). Based on selenium data of these formulas the selenium intakes of infants have been estimated to be about 6.6$\mu\textrm{g}$/day and 8.1$\mu\textrm{g}$/day in Korean by milk-based formula feeding.

In Korea, the concerns about the consumption of soy-based infant formulas have received considerable public attention. In has been known that the n-3/n-6 ratio of soy has a beneficial effect on the health. This study was conducted to investigate whether the soy-based infant formula has an effect on the composition of fatty acids in erythrocytes with regard to the plasma lipid levels in full-term infants. The infants who were delivered at Kyung Hee Medical Center were recruited. Experimental groups were the breast milk group(n=17), soy-based infant formula group(n=12) and casein-based infant formula group(n=19). Anthrophometic and dietary assessments were performed and the composition of RBC fatty acids and blood lipid levels were measured. The body weight, length, chest circumference and head circumference of the subjects were normal growth range showing no significant difference among the experimental groups. The ratio of n-3/n-6 ratio in breast milk, soy-based infant formula and casein-based infant formula were 0.11, 0.14 and 0.13, respectively. N-3/n-6 ratio of the subjects erythrocyte fatty acids for each groups were 0.18, 0.21 and 0.17, respectively. Most of the fatty acids of erythrocyte were not significantly different among the three experimental groups. The blood lipid levels of each experimental group were normal range. The total lipid level of casein-based formula group was higher than that of other experimental groups and LDL-cholesterol level of soy-based formula group was the lowest among the three groups.

Some pediatric patients who can not eat orally depend on enteral tube feedings, and some patients require more nutrients and calories to achieve the catch-up growth. If a patient is counting on the parenteral nutrition, early initiation of enteral feeding, orally or enterally, is a very good for the intestinal mucosal maturity and motility. There are numerous kinds of formulas and supplements for the enteral feeding for neonates, infants, and children. Depending on the intestinal symptoms, allergic symptoms, requirement of special nutrients, we can choose regular infant formula (milk-based, soy-based), protein hydrolysate formula, amino acid hydrolysate formula, elemental formula. Proper use of these formulas would help for the pediatric patients to recover from their diseases, to facilitate the intestinal mucosal maturity and to achieve their goal of growth.

Upon the assumption that the available components in the soil evaluated by present analytical procedures, are as effective as the components applied to the soil as fertilizer, some formulas for the calculation of fertilizer requirements (F. R) for crops are suggested. Basically, the formulas are derived by combining the country average values of soil test data(${\overline{ST}}$) and of the optimum rate of fertilizers (ORF) for crops obtained from N.P.K. trials in farmer's field, as following. $$F.R(kg/10a)={\overline{ST}}(kg/10a)+ORFkg/10a-ST(kg/10a)$$ where, ST denotes the available components tested in the soil under question. Although this formula can be used both for P and K fertilizers, considering the significance of the potassium saturation rate of the soil for the availability of K, for the calculation of K fertilizer requirement, following formula is suggested. $$F.R(kg/10a)=(C.E.C.{\times}B.S.R.K.-KST(me/100g){\times}CF$$ where, B. S. R. K. is the basic potassium saturation rate of the soil and CF is conversion factor for the conversion of K me/100g into $K_2O$ kg/10a. The B. S. R. K. for different crops are obtained from the country average values of soil exchangeable K (${\overline{KST}}$), cation exchange capacity (CEC) and the optimum rates of K fertilizers for crops (ORF $K_2O$). $$B.S.R.K.=\frac{{\overline{KST}}{\times}CF+ORF(K_2O)}{CEC{\times}CF}$$ Using these formulas, equations for P and K fertilizer requirements for rice, barley, wheat, corn, italian millet, soy bean, sweet potato, potato and rape are derived.
