The purpose of this study was to investigate encouragement experience on breastfeeding of health professionals, and the support in their hospitals on breastfeeding. A questionnaire on breastfeeding was administered to the obstetricians, pediatricians and nurses at the department of pediatrics or obstetrics of university hospital and private hospital in Seoul and Choong-Chung Province in South Korea. Total numbers of study subjects were 346 (pediatrician 67, obstetrician 41, nurse 238). Data was statistically analyzed according to descriptive statistics, Chi-square test and multivariant analysis. The results were as follows : 1. Most of the respondents (93.6%) had a knowledge regarding breastfeeding which had more advantage than formula-feeding. But their experience to educate the mother about breastfeeding was very limited (34.8%). The major problems were insufficient concern of healthcare professionals, no trained personnel's and lack of education programs on breastfeeding. 2. Most of the respondents (82%) had learned breastfeeding management in class at the university. But 2/3 of them had not been educated on breastfeeding management after graduation. 3. More than half of the hospitals had no breastfeeding education programs. And they recommended the formula-feeding to the mothers. 4. Seventy percent of the respondents recognized that breastfeeding information offered to the mothers in their hospitals might help to increase the rate of breastfeeding. But only 40% of hospital had offered breastfeeding information using pamphlets or brochures. In our study, a majority of respondents had not been educated on breastfeeding after graduation. A personal experience in breastfeeding is known predictor of confidence in breastfeeding. Educational programs may have an effect to change the health professionals behavior. Therefore, it is necessary to assist health professionals in obtaining more knowledge about breastfeeding. Continuing education programs to health professionals should be offered by nation and regional organization.

The antiulcer effects of newly synthesized prostaglandin derivatives were investigated in various experimental ulcer models and on gastric secretion in rats. HK-3 and HK-4, PG $E_2$derivatives, prevented the formation of acute gastric ulcer induced by ethanol or aspirin in pylorus-ligated rats. The ulcer formation was moderately inhibited by HK-1 and HK-2, PG $F_{2{\alpha}}$ derivatives, and aggravated by SK-1, SK-2 and SK-3, PG $F_{2{\alpha}}$ derivatives. HK-3 and HK-4 reduced the volume, acid output and pepsin output of gastric juice in pylorus-ligated rats. The gastric perfusion with physiologic saline(pH 6.0) showed relatively constant acid secretion and indomethacin increased the acid secretion. The acid secretion was markedly decreased by PG $E_2$but PG $F_{2{\alpha}}$ caused little change. Prostaglandin derivatives, especially HK-3 arid HK-4, significantly inhibited the acid secretion induced by indomethacin. The results show that, PG $E_2$ derivatives, HK-3 and HK-4, inhibit acid secretion and also have protective effects on gastric ulceration induced by ethanol or aspirin.

Purpose: This study was performed to systematically review the recently published nursing intervention studies. Methods: The literature was identified through the Korean Education and Research Information Service (KERIS), the Korean Information Service System (KISS), and National Assembly Library websites. Key words such as breast cancer, nursing, and intervention were used. The factors analyzed are as follows: 1) the characteristics of studies and study populations, 2) the classification of interventions, 3) outcome indicators and their effects, and 4) effective interventions. Results: Thirty two studies were included. Seventeen studies used a single intervention such as aerobic dance, TaiChi, foot massage, aromatherapy, or a stress-reduction method. Fifteen studies used combined interventions, including education, exercise, counseling, support, yoga or meditation. The data on 47 outcome indicators and their effects were segregated into psycho/spiritual outcomes, stress coping, physical outcomes, cardiorespiratory function, symptom management, arm and shoulder functions, fatigue, and quality of life. Some interventions had positive effects on stress, fatigue, and functions of shoulder. Conclusion: Various interventions are available for breast cancer patients, and some have had positive effects. However, more studies are required to develop evidence-based practice guidelines for nursing interventions.

Objectives: The aim of this review was to investigate whether evidence of complementary and alternative medicine (CAM) was reflected in clinical practice guidelines (CPGs) for insomnia based on relevant clinical trials. Methods: We conducted a systematic search on domestic and international CPG databases and medical databases. In addition, we conducted manual searches of relevant articles. Three authors independently searched and selected relevant studies; any disagreement was resolved by discussion. We extracted and analyzed the following data: published language, country, development group, participants, interventions, presence or absence of recommendations for CAM, level of evidence, grade of recommendation for CAM, and methods of development. Results: We identified 8,241 records from domestic and international databases, and 22 CPGs were included. Eleven of the 22 CPGs mentioned CAM interventions including herbal medicine, relaxation, acupuncture moxibustion, Tai Chi, meditation, hypnosis, biofeedback, Tuina, and external herbal medicine. However, most of the CPGs indicated 'no recommendation' or 'weak recommendation' for CAM interventions. Only Valeriana dageletiana Nakai and relaxation were considered to have experimental evidence. Valeriana dageletiana Nakai was recommended for improvement of sleep latency, sleep maintenance, total sleeping time, and sleep cycle. Relaxation was recommended as effective intervention for relieving physical and psychological arousal. Conclusions: Despite systematic reviews and randomized controlled trials on CAM for insomnia, most of the CPGs for insomnia did not reflect the evidence obtained. Further CPGs for insomnia should be developed by considering the current advanced studies in the field of CAM.

Chewing betel quid is associated with an increased risk of oral cancer. The betel quid chewed in Taiwan includes the inflorescence of Piper betle, which contains high concentrations of safrole (15 mg/fresh weight). Piper betle leaf is also used in betel quid; however, the concentration of safrole in betel leaf has not been documented. Chewing betel quid may contribute to safrole exposure in man (420 mm in saliva). Using $a^{32}$P-postlabeling method, we have recently demonstrated the presence of stable safrole-like DNA adducts in human oral tissues following betel quid chewing. Safrole is a rodent hepatocar-cinogen, and the real nature of safrole-DNA adducts in human tissues beside oral has not been elucidated. In this paper, we tested the safrole DNA adducts forming potential in human hepatic and oral derived cells by the ${32}^P$-postlabeling technique. The results suggest that oral cancer derived cell OC-2 alone is not able to form safrole-DNA adduct. However, safrole DNA adducts can be detected following I'-hydroxysafrole, a proximate safrole metabolite, treatment. In addition, pretreament of cytochrome P450 inducers also enhanced the formation of previously undetectable safrole DNA adducts. This finding couples with our previous results suggest that oral may serve as a target tissue for safrole, and safrole may be involved in oral carcinogenesis.

Objectives: This study surveyed doctors of Korean medicine on how they treat hypertension in their Korean clinical practices. Methods: An invitation to take an Internet-based questionnaire was sent to doctors who were registered in the Association of Korean Medicine in September 2016. Participants were first asked general profile questions, which included age, gender, work experience as a practitioner, and specialties. Second, they were asked whether they had experience with hypertension treatment and additional questions related to hypertension. Results: A total of 991 replies were received to the questionnaire. Most of the Korean medical doctors (95%) had blood pressure units and had monitored blood pressure. A majority of the Korean medicine doctors (55%) had provided hypertension treatment. Acupuncture and herbal medicine were commonly used for the treatment of hypertensive patients. In addition, bloodletting, moxibustion, pharmacopuncture, cupping, Chuna, Qigong exercise, meditation, and Tai Chi were used. Many doctors also recommended lifestyle modification. The respondents said that Korean medicine improves general health conditions (42.6%) and has low adverse effects (29.9%). One of the most common opinions about the revitalization measures of Korean medicine was expanding health insurance benefits (20.8%). Conclusions: Through this survey, we found out information about the present situation of hypertension treatment in Korean medicine. In the future, it is possible that hypertension treatment using Korean medicine will be demanded and used by practitioners if it is covered by public health insurance.

This study was carried out to select oyster mushroom strains tolerant to salinity and characteristic cultivation by different NaCl concentration. Among the 64 strains, Kimjae-10ho, Nongki-2-1ho, Myungyul, Byungneutari-1ho, Bupyungsoyae-1ho, Sambok and Chunchu-2ho resulted in higher mycelial growth and density on PDA medium containing NaCl. The maxium NaCl concentration possible to fruit body formation was 0.5% NaCl in Myungyul, 1.0% NaCl in Kimjae-10ho and Bupyungsoyae-1ho, 1.5% NaCl in Nongki-2-1ho, Byungneutari-1ho, Sambok and Chunchu-2ho, respectively. Increased NaCl concentration on sawdust medium prolonged culture period, while decreased total quantity and come to be short and thin in Length and thickness of stipe. Higher NaCl concentration in the medium decreased the uptake rate of $K_2O$ and CaO, whereas increased the NaCl uptake rate.

Objective: This study assessed the effects of probiotics on cecal microbiota, gene expression of intestinal tight junction proteins, and immune response in the cecal tonsil of broiler chickens challenged with Salmonella enterica subsp. enterica. Methods: One-day-old broiler chickens (n = 240) were randomly allocated to four treatments: negative control (Cont), multi-strain probiotic-treated group (Pro), Salmonella-infected group (Sal), and multi-strain probiotic-treated and Salmonella-infected group (ProSal). All chickens except those in the Cont and Pro groups were gavaged with 1×10⁸ cfu/mL of S. enterica subsp. enterica 4 days after hatching. Results: Our results indicated that body weight, weight gain, and feed conversion ratio of birds were significantly reduced (p<0.05) by Salmonella challenge. Chickens challenged with Salmonella decreased cecal microbial diversity. Chickens in the Sal group exhibited abundant Proteobacteria than those in the Cont, Pro, and ProSal groups. Salmonella infection downregulated gene expression of Occludin, zonula occludens-1 (ZO1), and Mucin 2 in the jejunum and Occludin and Claudin in the ileum. Moreover, the Sal group increased gene expression of interferon-γ (IFN-γ), interleukin-6 (IL-6), IL-1β, and lipopolysaccharide-induced tumor necrosis factor-alpha factor (LITAF) and reduced levels of transforming growth factor-β4 and IL-10 compared with the other groups (p<0.05). However, chickens receiving probiotic diets increased Lactobacillaceae abundance and reduced Enterobacteriaceae abundance in the ceca. Moreover, supplementation with probiotics increased the mRNA expression of Occludin, ZO1, and Mucin 2 in the ileum (p<0.05). In addition, probiotic supplementation downregulated the mRNA levels of IFN-γ (p<0.05) and LITAF (p = 0.075) and upregulated IL-10 (p = 0.084) expression in the cecal tonsil. Conclusion: The administration of multi-strain probiotics modulated intestinal microbiota, gene expression of tight junction proteins, and immunomodulatory activity in broiler chickens.
