Purpose: This study was conducted to investigate the effect on factors related lactation after administration of Palmul-tang in postpartum C57BL/6N mice. Materials and Methods: Experimental groups were divided into control group post-par group and pre-par group. Pre-par and post-par group were administered Palmul-tang(p.o) twice a week for 4 weeks or 3 weeks respectively. Control group was administered normal saline for 3 weeks. Then we observed morphological change, immunohistochemical density and milk protein gene expression of factors related lactation within mammary gland of postpartum mice. Results: In post-par and pre-par groups, adipose tissue within mammary gland significantly decreased, and ductal branch and alveoli prominently developed than that of control group at 1~3 weeks after administraion of Palmul-tang. In post-par and pre-par groups, density of immunoreactivity on oxytocin, prolactin, estrogen and progesterone receptors in mammary glandular tissue significantly increased than that of control group. mRNA expression of $\beta$-casein and placental lactogen (PL)-1 in post-par group was more increased than that of control and pre-par groups. Conclusion: These results suggest that Palmul-tang significantly improved factors related lactation at postpartum period.

Objectives : Many women associate one or more of their pregnancies with the development of adult obesity. This study was designed to determine influencing factors on postpartum weight retention and whether the breast-feeding was available to weight loss in puerperium. Methods : Articles from the literature on 'postpartum weight retention' were examined. Results : These articles show that different factors were related with postpartum weight retention. This study suggests that moderate weight gain during pregnancy is important to prevent postpartum maternal obesity. Especially weight gain from 20 weeks to 36 weeks of pregnancy is important. Falling in depression and anxiety during postpartum period should be avoided and social support is also needed. Delivery at the financially secure status is also recommended. Sufficient physical activity and exercise are needed to prevent from postpartum weight retention. Weight loss with dieting and exercise during lactation don't have a bad influence on the growth of infants.

The longitudinal changes on human milk volume of 27 Korean lactating women (primiparae=10, multiparac=17) from 0.5 to 6 months after parturition have been studied by test-weighing method in Cheongju and Anseong area. The human milk volume per day increased to 2 months postpartum, and then decreased during lactation. The mean volume(g/day) at 0.5, 1, 2, 3, 4, 5, and 6 months were 634, 810, 847, 840, 844, 810, and 732g, respectively. The average volume were 791 ($\pm$149) and 786($\pm$131)g for primiparae and multiparae, respectively. The overall mean volume was 788$\pm$135g/day. The distributions of the individual mean volume during the first 6 months of lactation were found 450~549g(3.7%), 550~649g(11.1%), 650~749g(22.2%), 750~849%(37.1%), 850~949g(18.6%), 950~1049g(3.7%), and 1050~1149g(3.7%). The mean volume between primiparae and multiparase was significantly lower than other periods. The peak milk volume during the lactation was observed at 3 months postpartum for primiparae(40%), 2 months postpartum for multiparae(35.3%), and 2 months postpartum for total lactating women(29.6%). The volume of human milk had a significant positive correlation with peak volume and infant milk intake, but no correlation with maternal age, weight before delivery, height, and birth weight.

The purposes of this study was to investigate selenium content of human milk and selenium intake of breast-fed infants at each period of lactation longitudinally. The human milk intake in breast-fed infants was measured by test weighing method from 20 lactating mothers at 1,2 and 3 months postpartum. Selenium content in the milks was determined by atomic absorption spectrophotometry with hydride generation after wet digestion of samples. Selenium intake in breast-fed infants was calculated by multiplying human milk intakes by selenium contents. The milk intakes were 640, 726 and 715g/day at 1,2 and 3 months postpartum. The selenium contents in human milk were characterized by a pattern of slight decline with advancing stage of lactation;13.1, 11.5 and 9.8$\mu\textrm{g}$/L at 1,2 and 3 months during lactation. There was a large individual variation at any stage of this study. The mean dietary selenium intakes in breast-fed infants were 8.38, 8.32 and 6.97$\mu\textrm{g}$/day at 1,2 and 3 months postpartum, respectively. The mean daily intakes on a body weight basis were gradually decreased during the course of lactation.

Plasma and milk samples of 24 periparturient Holstein cows were collected from 1 week prepartum to 10 week postpartum to measure the effects of parity on mineral status in periparturient cows. Cows were fed mainly mixed ration with the concentrate supplement during the experimental period to meet nutrient requirement of dairy cattle for TDN, protein, and minerals, Plasma Ca of cows decrease as parity increased, but plasma Mg, K, Fe and Zn were lowest in the first lactation cows. Plasma inorganic P, Na, and alkaline phosphatase were not affected by the parity. Plasma Ca, Fe and Zn of cows decreased at parturition, but plasma Mg increase. Plasma Ca of the first, second and third and more lactation cows at parturition were 9.65, 8.96, and 8.92 mg/dl, respectively. Colostral Ca, P, Mg, Na, and Zn were highest in the first lactation cows, although colostrum yield was lower. Milk yield from 1 to 10 weeks postpartum was lowest in the first lactation cows, but mineral concentrations in milk were not affected by the parity.

Major objective was to evaluate three doses of bST (POSILAC(R)) injected into Holstein cows during the transition period and through 56 d of lactation for potential to improve DMI, BCS, BW, metabolites, hormones, IGF-I and milk production. Biweekly injections of bST (0, 5.1, 10.2, or 15.3 mg bST/d) began 28 d before expected parturition and continued through 56 d postpartum. Twenty-three of the 25 multiparous Holstein cows assigned randomly to four groups completed experiment (7, 5, 6 and 5 cows/group, respectively). The DMI, BW and BCS were recorded weekly throughout the prepartum and postpartum periods and blood samples were collected thrice weekly for analyses of ST, insulin, $T_{4}$, $T_{3}$, IGF-I, glucose and NEFA. Milk yields were recorded daily through 60 d postpartum and milk components measured once weekly. Mathematical model for data analyses for prepartum and postpartum periods included treatment, calving month, and the two-factor interaction. Cows injected with 10.2 and 15.3 mg bST prepartum had greater mean prepartum concentrations of ST and IGF-I. Prepartum injections of bST did not affect prepartum BW or BCS. On average, cows injected postpartum better maintained their BCS during first 60 d of lactation (3.15$\pm$0.06, 3.12$\pm$0.007, 3.20$\pm$0.006 and 3.58$\pm$0.009). Treatments did not affect mean prepartum DMI but cows injected with 15.3 mg bST/d had greatest DMI and greatest mean daily MY during the first 3 wk and tended to be greater during first 60 d of lactation. Cows injected with two highest bST doses (10.1 and 15.2 mg/d) had greater mean postpartum concentrations of ST and $T_{3}$, but IGF-I, $T_{4}$, glucose and NEFA did not differ across groups. No adverse effects of bST treatment were observed.

Objective : This study was conducted to investigate the effect of Mokhyangsaenghwa-tang (MS) and Mokhyangsaenghwa-tang plus Cervi Pantotrichum Cornu (MS-C) on postpartum recovery and lactation. Materials and Methods : We used 18-week pregnant Spraque Dawley rats and administered the decoctions of MS and MS-C to rats once a day for 4 days or 8 days. Then we observed changes in the body weight of pup rats and complete blood cell count, liver function test, renal function test, mammary gland tissue, level of serum prolactin, ${\beta}-casein$ and WAP of postpartum rats. Result : A significant increase in body weight was observed in MS-C treated pup rats compared with in MS treated group. The levels of WBC and platelet from MS group and MS-C group were decreased compared with the control group. The levels of RBC, hemoglobin and hematocrit from MS group and MS-C group showed statistically significant increases compared with the control group. The levels of protein, albumin from MS group and MS-C group were increased compared with the control group. The levels of BUN, creatinine from MS group and MS-C group did not show statistically significant changes compared with the control group. The mammary gland tissues from MS group and MS-C group showed increased angiogenesis. The levels of serum prolactin from MS group and MS-C group were increased compared with the control group. The expression of ${\beta}-casein$ and WAP genes from postpartum rats treated with MS and MS-C was increased. Conclusion : This study shows that MS and MS-C improved postpartum recovery and lactation in rats.

Purpose : This study was conducted to investigate the effect of Mokhyangsaenghwa-tang beverage on postpartum recovery and lactation. One theory of oriental medical treatment for postpartum care is focused on increasing vitality and building up blood. Saengwha-tang are representative remedies for these respective principle of treatment. This experiment was carried out to evaluate the clinical effects of Mokhyangsaenghwa-tang on blood components, Body weight, BMI and prolactin level in postpartum. Methods : 65 postpartum women applied for this study, and 30 of them were included in this study. They were divided two groups. The experimental group were treated by Mokhyangsaenghwa-tang beverage, the control group were treated by citron beverage during 40 days. Then we observed the changes of the body weight, BMI, complete blood cell count, liver function test, renal function test, level of serum prolactin, Urine analysis and general conditon Questionnaire among baseline(before treatment), 1st phase(after 20 days treatment) and 2nd phase(after 40 days treatment). Results : After taking Mokhyangsaenghwa-tang beverage, body weight, body water, edema index, prolactin ana general condtion became better, but they were not statistically significant. Conclusion : This study shows that Mokhyangsaenghwa-tang can improve postpartum recovery, but more research is needed.
