Effects of galactagogue herbal tea containing Chrysanthemum indicum as the main component on milk production in postpartum rats / 한국영양학회지

Purpose@#Breastfeeding is the optimal method for feeding a newborn. But insufficient breast milk is the major reason why mothers give up breastfeeding. Herbal galactagogues have been used increasingly to treat postpartum hypogalactia. This study examined the effect of an herbal tea containing Chrysanthemum indicum, as the main ingredient, on milk production in lactating rats. @*Methods@#The herbal tea contained C. indicum (27%), Foeniculum vulgare Mill (21%), Pimpinella anisum (18.2%), Carum carvi (16.1%), Urtica dioica (14.7%), and Gardenia jasminoides (3%). Sixteen lactating Sprague-Dawley (SD) rats were divided randomly into 2 groups, the normal control group (NC; n = 8), and the galactagogue herbal tea group (GHT; n = 8) for 7 days. Lactating rats were administered the decoction of an herbal galactagogue mixture by oral gavage or the same amount of distilled water and milk production was assessed by measuring the pups' weights during the suckling period. The blood concentrations of prolactin, cortisol, oxytocin levels and mammary gland tissues were examined to assess the effects of the galactagogue. @*Results@#Milk production was 9.2% higher in the GHT group given the herbal tea than in the NC group and the difference was statistically significant. The cortisol level in the GHT group was 17.2% higher than the NC group. The herbal tea containing C. indicum increased the size of the alveoli epithelium cells and the mammary lobe. @*Conclusion@#The present study revealed the potential of herbal tea containing C. indicum to enhance milk production in postpartum SD rats.

Nutritional Management of a Patient with a High-Output Stoma after Extensive Small Bowel Resection to Treat Crohn's Disease

For patients with short bowel syndrome who undergo ileostomy, nutritional management is essential to prevent complications associated with a high-output stoma (HOS). We report a practical example of ostomic, medical nutrition therapy provided by an intensive nutritional support team (NST). A 42-year-old male with a history of Crohn's disease visited Seoul National University Hospital for treatment of mechanical ileus. He underwent loop ileostomy after extensive small bowel resection. As his remaining small bowel was only 160 cm in length, the stomal output was about 3,000 mL/day and his body weight fell from 52.4 to 40.3 kg. Given his clinical condition, continuous tube feeding for 24 h was used to promote adaptation of the remnant bowel. Thereafter, an oral diet was initiated and multiple, nutritional educational sessions were offered by dietitians. Constant infusion therapy was prescribed and included in the discharge plan. Two months after discharge, his body weight had increased to 46.6 kg and his hydration status was appropriately maintained. This case suggests that the critical features of medical nutritional therapy for ostomy management are frequent assessments of fluid balance, weight history, and laboratory data and after nutritional interventions.

Involvement of heme oxygenase-1 induction in anti-vascular inflammation effects of Xanthoceras sorbifolia in human umbilical vein endothelial cells.

OBJECTIVE: To define the effects of Xanthoceras sorbifolia (EXS) on vascular inflammation and the mechanisms in endothelial cells. METHODS: Vascular protective effects of an ethanol extract of seeds from EXS (1-50 µg/mL) against tumor necrosis factor-α (TNF-α)-induced vascular inflammation were examined in human umbilical vein endothelial cells (HUVECs). RESULTS: EXS significantly decreased TNF-α-induced expression of cell adhesion molecules, such as intracellular adhesion molecule-1, vascular cell adhesion molecule-1, and endothelial cell selectin, in a dose-dependent manner. Pre-treatment with EXS significantly inhibited translocation and transcriptional activity of nuclear factor-κB (NF-κB) increased by TNF-α. EXS also significantly inhibited formation of intracellular reactive oxygen species (ROS). Moreover, the vascular protective effects of EXS were linked to up-regulation of heme oxygenase-1 (HO-1) and nuclear factor E2-related factor-2 (Nrf-2) expression. EXS-induced HO-1 expression was significantly decreased in SnPP (HO-1 inhibitor)- and HO-1 siRNA-treated cells, whereas an increase was found in cobalt protoporphyrin IX (CoPP) (HO-1 inducer)-treated cells. In addition, pretreatment with EXS increased HO-1 and Nrf-2 expression under TNF-α stimulation with or without N-acetyl-L-cysteine. Furthermore, the inhibitory effects of EXS on TNF-α-induced vascular inflammation were partially reversed in SnPP- and of HO-1 siRNA-treated cells but increased by CoPP. CONCLUSION: These results suggest that EXS may have important implications for prevention of vascular complications associated with vascular inflammation by inhibition of the NF-¦ÊB/ROS pathway and activation of the Nrf-2/HO-1 pathway.

Beneficial Effect of Berberis amurensis Rupr. on Penile Erection / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate whether the methanol extract of Berberis amurensis Rupr. (BAR) augments penile erection using in vitro and in vivo experiments.</p><p><b>METHODS</b>The ex vivo study used corpus cavernosum strips prepared from adult male New Zealand White rabbits. In in vivo studies for intracavernous pressure (ICP), blood pressure, mean arterial pressure (MAP), and increase of peak ICP were continuously monitored during electrical stimulation of Sprague-Dawley rats.</p><p><b>RESULTS</b>Preconstricted with phenylephrine (PE) in isolated endotheliumintact rabbit corus cavernosum, BAR relaxed penile smooth muscle in a dose-dependent manner, which was inhibited by pretreatment with NG-nitro-L-arginine methyl ester (L-NAME), a nitric oxide synthase inhibitor, and H-[1,2,4]-oxadiazole-[4,3-α]-quinoxalin-1-one, a soluble guanylyl cclase inhibitor. BAR significantly relaxed penile smooth muscles dose-dependently in ex vivo, and this was inhibited by pretreatment with L-NAME H-[1,2,4]-oxadiazole-[4,3-α]-quinoxalin-1-one.

An Adequate Intake of Carbohydrates for Gestational Diabetes Mellitus / 임상당뇨병

Gestational diabetes mellitus (GDM) is commonly defined a frequent metabolic condition associated with pregnancy that leads to substantial maternal and perinatal complications. Medical nutrition therapy (MNT) is the cornerstone treatment on patients with GDM, and accordingly, it has a significant impact in women and newborns. The main purpose of MNT in GDM is carbohydrates because they are the major nutrient affecting postprandial euglycemia. Recent epidemiological studies suggest that low-carbohydrate intake is related to beneficial effects on maternal and newborn outcomes. Current evidence consistently supports the advantages of using the glycemic index for additional benefit. Therefore in this context, we will discuss from summarize studies involving carbohydrate in GDM. In addition, this article describes the efficacy of low glycemic index diet for the management of GDM.

Use of Dietary Supplements and Determinants of Taking Dietary Supplements by Gender in the Korean Population: Using the 4(th) Korean National Health and Nutrition Examination Survey (2007-2009) / 대한지역사회영양학회지

OBJECTIVES: Although dietary supplements use in Korea has been rapidly increasing and women are more likely to take dietary supplements more than men, only a few studies have been conducted to investigate factors contributing to gender differences in dietary supplement use in the Korean population. The aim of this study is to evaluate the prevalence of dietary supplement use and also identify gender-specific key factors that contribute to it using the data of the 4th KNHANES. METHODS: Subjects were divided into user and non-user groups according to the answer given to the question that asked whether they had used any dietary supplement for more than 2 weeks on a regular basis during the previous year. Factors related to dietary supplement use were examined by general characteristics, health behavior and eating behavior. RESULTS: Prevalence of dietary supplement use was 13.6% for men and 20.6% for women. Users were more likely to be middle-aged, have higher income and education, have a spouse, or reside in dong areas in both men and women. Regarding health behaviors, men with desirable lifestyle behavior were more likely to take dietary supplements, while men who smoked were less likely to take dietary supplements. Regarding disease history, both men and women with a current disease had higher odds of taking supplements. With regard to dietary behavior, frequent eating out and nutrition attitude were associated with higher odds of taking supplements in both men and in women. CONCLUSIONS: Health or dietary behavior related factors that were associated with taking supplements differed by gender. These findings can be useful for planning gender-specific dietary education and health programs.

Recurrent Anencephaly in A Same Pregnant Women: Report of Two Cases / 대한산부인과학회잡지

The etiology of neural tube defects, a category encompassing spina bifida, anencephaly and encephalocele, remains highly controversial and unclear, However, there is overwhelming evidence supporting a multifactorial etiology for this group of defects. Recent studies have shown that folic acid supplements taken periconceptionally can reduce a woman's risk of having a child with a neural tube defect. Qenetic screening could identify women who will require folic acid supplements periconceptionally to reduce their risk of having a child with a neural tube defects. Recently, we encountered two cases of recurrent anencephaly that had occurted in a same pregnant woman in our hospital. We report these two cases with brief review of the literatures.

A case report of suprerior mesenteric vein thrombosis associated with diverticulitis / 대한내과학회지

Mesenteric vein thrombosis is a rare disease that can be fatal, as it can cause ischemia or infarction of bowels. The mortality rate is 13~50%. The predisposing factors of mesenteric vein thrombosis are numerous, and one of them is diverticulitis. Diverticulitis is a rare disease and mesenteric vein thrombosis caused by diverticulitis has not been reported in Korea. We report a patient with superior mesenteric vein thrombosis associated with diverticulitis of ascending colon, and it was diagnosed by computed tomography and barium enema. After antibiotic therapy, the thrombosis was resolved and the patient was completely recovered.
