This study was conducted to assess the relationships between maternal dietary intakes and milk contents of minerals and trace elements, and the correlation among levels of these milk constituents. Maternal dietary intakes were measured and milk samples were collected at 2∼5 days, 2, 4, 6 and 12 weeks postpartum from 29 lactating women. The results obtained are sumarized as follows: 1) The overall mean nutrient intakes of lactating women in this study were below the recommended allowances and there were extensive individual variations between subjects. 2) Concentrations of minerals and trace elements in matured human milk showed the same range reported from different countries with the exception of calcium, magnesium, manganese and molybdenum which were relatively high. 3) There were no significant relationships between maternal dietary intakes of minerals and the corresponding mineral levels of human milk. In addition, no significant correlations were found between maternal vitamin C intake and the iron contents of milk. These were significant positive correlations between maternal calcium intake and the magnesium level of milk ; between maternal protein intake and the contents of zinc and copper in human milk. Maternal energy intake was negatively correlated with milk sodium level. 4) Pearson correlation coefficient showed positive significant relationships between levels of 17 pairs of various mineral and trace elements : sodium and potassium, iron ; potassium and calcium, phosphors, magnesium, iron, copper, manganese ; calcium and magnesium, iron manganese, molybdenm, nickel ; magnesium and iron, molybdenum ; iron and copper ; nickel and manganese.

The most abundant long-chain polyunsaturated fatty acid in brain lipids is docosahexaenoic acid(C22 : 6 N-3, DHA). It is incorporated into nerve tissues mostly in utero and during the first year of life. DHA in brain is derived from either pre-formed DHA in human milk or by infant hepatic synthesis from linolenic acid in milk. This study was designed to investigate the effects of DHA supplementation on fatty acid profiles in maternal plasma lipid and breast milk. Twenty lactating women participated in the study. Seven women took 3g of fish oil per day and vitamin E for 28 days starting from the day of giving birth. Five women consumed 1.5g of fish oil as well as tivamin E, and the rest took vitamin E supplements for the same period of time. Dietary questionnaires and 3 consecutive 24-h recalls were collected to evaluate theri nutritional status and food habits. Finding that DHA intake from fish was not significantly different among three experimental groups, the partcipants were instructed to continue eating their usual home diets. Milk samples were taken on the day of giving birth, as well as the 7th, 14th and 28th day being the supplement phase, and finally 2 weeks after the cessating of DHA supplements. The amounts of the fish oil supplements produced significant dose-dependent increased in the DHA content of milk and plasma, but to a lesser degree. Base-line for 28 days raised the level to 2.05$\pm$0.43% and 1.5g/day supplement produced DHA levels of 1.02$\pm$0.19%. The results of this study indicated that relatively small amount of dietary DHA supplementation significantly elevats DHA content in milk. This would clearly elevate the infant's DHA intake which in turn may have implications for the infant's brain development.

Background & Objectives: Polycystic ovarian syndrome (PCOS) is one of the commonest endocrine abnormality in women of reproductive age affecting from 4% - 21% of the reproductive women and is characterized by chronic anovulation and hyperandrogenism. The aim of the study was to evaluate the effect of majoon idraare haiz in menstrual regulation and morphological changes in ovaries in poly cystic ovarian syndrome. Methods: A Pilot study was carried out in the department of Ilmul qabalat wa amraze niswan, National institute of unani medicine, hospital, Bengaluru. Fifteen Patients of PCOS aged 18-35 diagnosed using Rotterdam criteria were included in the study. Patients with insulin sensitizing treatment within 3 months, hormonal treatment and those with h/o diabetes mellitus, hypertension, pregnant and lactating women were excluded.Majoon idraare haiz was administered orally at a dose of 10 g with 20 ml arqbed mushk once daily from fifth day of cycle for 21 days for three consecutive cycles. Primary outcome measure was menstrual regularity while changes in USG pelvis(normal ovarian morphology) was considered as secondary outcome measure. In addition, duration of flow and changes in basal metabolic index (BMI), modified Ferriman Gallwey (mFG) score, acanthosis nigricanswere observed. Data were analyzed using, ANOVA, paired student 't' test, fisher exact test. Results: Changes in duration of cycle, duration and amount of flow was achieved in 93.3% patients with p<0.0001 and 46.6% patients showed normal findings on pelvic ultrasonography with p=0.006. In addition, significant changes were also observed in BMI, hirsutism and acanthosis nigricans with p value of 0.0001, p=0.003 and p=0.009 respectively Conclusion: Majoonidraare haiz can be used as an effective alternative in management of PCOS patients. It has significant effect on menstrual regulation and changes in polycystic ovarian morphology to normal.

This study was conducted to identify the factors affecting breastfeeding in adult women based on socio-demographic and health-related characteristics using the results of KNHANES VII-3. The data was analyzed by applying weights, using the complex sample analysis method of the SPSS Win 22.0 program. Breastfeeding was influenced significantly by age, education level, and the current smoking status. Women in the age group of 30-39 years had a breastfeeding rate that was 3.06 times higher than 19-29 year old women. Also, the breastfeeding rates for women with an education level under elementary school were 4.70 times higher than those with a college degree or higher education level and non-smokers and ex-smokers had levels 2.51 times higher than smokers. Therefore, for mothers under the age of 30, education on breastfeeding should be further strengthened. For mothers over 40 years old, lactation support to increase the milk supply should be provided as well as assistance toward care for other children in the family. Also, better-educated mothers will need to learn effective breastfeeding methods in limited environments such as work-life, and a social atmosphere needs to be established that is considerate to lactating women. Furthermore, education related to pregnancy and lactation should be provided for use in smoking cessation programs for female smokers.

This study was to investigate the intake of human milk, sodium and potassium of breast-fed infants at 7, 15, 30, 60 and 90 days postpartum. Milk samples were obtained from 20 healthy lactating women living in In-Cheon area. Milk intakes of 20 breastfed infants were determined by the test-weighing method and soldium and potassium contents of human milk were analyzed by Atomic Absorptin Spectrophotometer after Wet-Digestion. Infant milk intakes per day tended to increase during lactation. The mean($\pm$SD) intakes at 7, 15, 30, 60 and 90 day were 460(164), 547(202), 626(199), 718(139) and 688(162)g/day, respectively. The sodium contents decreased significantly from 9.7(1.1)mEq/kg at 7 day to 6.3(1.8)mEq/kg at 90 day(p<0.05). The sodium intakes of infants were 100.8(39.6), 103.3(46.7), 107.2(47.9), 115.5(41.5) and 105.2(41.2)mg/day, respectively and average intake was 107.2(43.9)mg/day. The potassium contents were ranged from 10.5(1.3) to 13.3(2.3) mEq/kg and the potassium intakes of infants were 241.8(11.2), 267.8(98.8), 314.1(98.6), 318.0(66.1) and 276.1(62.6)mg/day, respectively and average intake was 288.3(91.8)mg/day. The mean sodium and potassium intakes of infants between boys and girls were not significantly different at 5% level.

This study was longitudinally conducted to evaluate the intakes of protein, Ca, Mg and P of exclusively breast-fed infants compared with the Recommended Dietary Allowances (RDA) for Korean infants. Twenty Korean lactating women and their infants during the first 3 months of lactation in Incheon area were participated. Protein, Ca and Mg, and P contents in the milk were determined using semimicro Kjeldahl (N ${\times}$ 6.38) , atomic absorption spectrophotometer and colorimeter, respectively, and also the milk consumption of the infants was measured by the test-weighing method. Protein contents of the milk were 1.96, 1.63, 1.51, 1.25 and 1.16 g/100 ml, and protein intakes of the breast-fed infants were 9.00, 9.85, 9.17, 8.97 and 7.76 g/day at 7, 15, 30, 60 and 90 days postpartum. The average protein intake per body weight of the breast-fed infants was 1.84 g/kg/day. The average intakes of Ca, Mg, P were 172.1 mg/day, 15.2 mg/day and 91.4 mg/day, respectively, and the average Ca/P ratio was 1.91. There was positive correlation between protein and Ca, protein and p, and Ca and P contents while negative correlation between Mg and P, The body weight of breast-fed infants increased normally from 3.6 $\pm$ 0.41 g at birth to three month during lactation. It is suggested that the breast-fed infants in Incheon area consume almost adequately protein, Ca and P from the milk compared with RDA for Korean infants.

Taurine is only supplied to the infants from the breast-fed or formula milks because the enzyme activities of taurine biosynthesis are limited in early stages of infants . The objectives of present study were to quantitate the contents of tarurine in human milk and to estimate the intake of taurine by breast-fed infants during early period of lactation. Thirty -three lactating women, volunteered and delivered in R hospital in Serou. were recruited. Milk samples were collected every day at B1-B5 day(from 1 to 5 day dafter start of milk secretion), 15th and 30th day postpartum. Taurine contents were determined by HPLC equipped with RF-detector. The intake of taurine by infants was estimated by multiplization with the infant milk intake reported in our laboratory. The content of taurine was 406$\pm$174nmol/ml at B1-B5 day, and then gradually decreased to 359$\pm$125nmol/ml at 15th day and to 304$\pm$94nmol/ml at 30th day postpartum. The estimated intake of taurine was almost same as 24-25mg/day at B1-B5 day, and 15th , 30th days postpartum . This results was due to the increase of the intake of milk by infants.

This study was longitudinally conducted to evaluate vitamin A intake of exclusively breast-fed infants compared with the Recommended Dietary Allowances (RDA) for Korean infants. Twenty-seven Korean lactating women and their infants during the first 6 months of lactation in Cheongju and Anseong areas were participated. Retinol and $\beta$-carotene contents in the milk were determined using HPLC and also the milk consumption of the infants was measured by the test-weighing methods. Vitamin A (retinol and $\beta$-carotene) contents of the milk were 65.7, 57.2, 48.1, 43.9, 38.2, 38.7 and 44.0 R.E./100 ml, and vitamin A intakes of the breast-fed infants were 361, 402, 348, 331, 304, 305 and 322 R.E./day at 0.5, 1, 2, 3, 4, 5 and 6 month of lactation, respectively. The average intake of vitamin A was 339.1 R.E./day and the percentage to RDA was 96.9% during 6 months. Vitamin A intakes per body weight of the breast-fed infants were 96.7, 88.3, 62.1, 50.0, 41.8, 39.3 and 39.6 R.E./kg/day at 0.5, 1, 2, 3, 4, 5 and 6 month. The body weight increased normally from 3.4 $\pm$ 0.5 kg at birth during lactation. It is suggested that the breast-fed infants in Cheongju and Anseong areas consumed adequately vitamin A from the milk compared with RDA for Korean infants.

This study was performed to investigate the vitamin A intake of exclusively breast-fed infants and to compare the value with the Recommended Dietary Allollwances(BDA) for Korean infants. We examined retinol and ${\beta}$-carotene contents of breast milk in 32 lactating women by HPLC analysis and also the consumed volume of the milk of their infants by the test-weighing method during the first 5 months of lactation. Total vitamin A contents of the milk shelved 67.3, 56.5, 51.2, 45.2, 39.0 and 34.lR.E./100m1 at 0.5, 1, 2, 3, 4 and 5 months of lactation respectively. Vitamin A intake of breast-fed infants were 320, 371, 368, 325, 292 and 251R.E/day during the five-month nursing period. Vitamin A intake per body weight of breast-fed infants was measured at 86.4, 79.8, 63.6, 49.1, 40.0 and 31.9R.E/kg/day. Body weight gain of infants was not affected by the vitamin A intake from the milk during the lactation. We conclude that breast-fed infants most likely receives vitamin A from the milk adequately compared with the RDA for Korean infants. (Korean J Nutrition 31(9) : 1433-1439, 1998)

The purpose of this study is to investigate zinc and copper intakes of exclusively breast-fed infants. We measured consumed volume and the minerals concentrations of human milk from thirty three lactating women and their infants during the first 5 months of lactation , Zinc concentrations of human milk showed 0.394, 0.290, 0.191, 0.147 and 0.139mg/100g at 0.5, 1, 2, 3, 4 and 5 months of lactation respectively. Copper concentrations in the milk showed 61.04, 45.97, 37.15, 3.94, 26.22 and 26.21$\mu\textrm{g}$/100g respectively. Consumed volume of the milk of infants were 515, 650, 718, 731, 746 and 769g/day. There is significant difference between boys and girls in consumed volume of the milk at 2, 3 and 4 months of lactation. Zinc intakes of breast-fed infants declined(p<0.05) from 2.13mg/day at 0.5 months to 1.21mg/day at 3 months with no change thereafter significantly. Copper intakes of the infants declined(p<0.05) from 323.2$\mu\textrm{g}$/day at 0.5 months to 238.9$\mu\textrm{g}$/day at 3 months with no change thereafter. Form this survey, the reevaluation of zinc and copper intakes and recommended dietary allowance of those minerals during infancy are merited. (Korean J Nutrition 33(8) : 857-863, 2000)
