This study investigated the effects of insoluble dietary fibers from pine (Pinus radiata D. Don) inner bark powder (PIBP) on loperamide constipation in rats. Male Sprague-Dawley rats were administered PIBP in their diets at concentrations of 5% and 10% for 4 weeks. Rats were divided in to four groups, normal diet group (Cont), a normal diet and loperamide group (Lop), 5% PIBP experimental diet and loperamide group (Lop+PIBP 5%), and 10% PIBP experimental diet and loperamide group (Lop+PIBP 10%). Constipation was induced by oral administration of loperamide (2 mg/kg, twice per day) for the last three days of the experiment. Food intake, body weight, properties of feces, gastrointestinal transit time, and serum lipid profiles were measured. When compared with the normal diet and loperamide group (Lop), there were increases in fecal pellet number (p<0.05), wet weight (p<0.001), and water content (p<0.001). Positive results were derived from relevant indicators to improve constipation. In addition, the number of fecal pellets in the colon was not significant, and decreased as PIBP content increased. PIBP had a concentration-dependent effect on reduction of total cholesterol, LDL-cholesterol, and triglycerides and elevation of HDL-cholesterol. These results indicate that PIBP may effectively prevent constipation.

Purpose: We evaluated the efficacy and safety of combined oral and enema therapy using polyethylene glycol (PEG) 3350 with electrolyte solution for disimpaction in hospitalized children. Methods: We retrospectively studied 28 children having functional constipation who received inpatient treatment between 2008 and 2016. The amount of oral PEG 3350 electrolyte solution administered was 50-70 mL/kg/d (PEG 3350, 3-4.1 g/kg/d), and an enema solution was administered 1-2 times a day as a single dose of 15-25 mL/kg (PEG 3350, 0.975-1.625 g/kg/d). A colon transit time (CTT) test based on the Metcalf protocol was performed in some patients. Results: Administration of oral and enema doses of PEG 3350 electrolyte solution showed $2.1{\pm}0.3$ times and $2.9{\pm}0.4$ times, respectively. After disimpaction, the frequency of defecation increased from $2.2{\pm}0.3$ per week to once a day ($1.1{\pm}0.1$ per day). The number of patients who complained of abdominal pain was reduced from 15 (53.6%) to 4 (14.3%). Before hospitalization, nine patients underwent a CTT test, and 5 of 9 patients (55.6%) were classified as belonging to a group showing abnormalities. And in some patients, mild adverse effects were noted. We examined electrolytes and osmolality before and after disimpaction in 16 of 28 patients, and no abnormalities were noted. Conclusion: In terms of therapeutic efficacy and safety, combined oral and enema therapy using high-dose PEG 3350 with electrolytes is considered superior to conventional oral monotherapy or combined oral and enema therapy on an outpatient basis.

Purpose: This literature review was performed to assess the effect of raisins on human health. Methods: A review of Medline was conducted using the keywords: 'raisins, raisins and health, raisins and cardiovascular disease (CVD), raisins and cancer, raisins and diabetes, raisins and fiber, raisins and colon health, raisins and antioxidants, raisins and inflammation, raisins and dental caries'. The reference lists from previous review articles on raisins and human health and the California Raisin Marketing Board files were reviewed for additional studies. Results: Raisins have one of the highest polyphenolic content and antioxidant ORAC levels compared to other traditional dried fruits. Many of the polyphenols in raisins are well assimilated and bioavailable. Raisin consumption reduces low density lipoprotein (LDL) cholesterol, blood pressure and blood sugar, when compared to equal caloric carbohydrate snacks and is associated with a reduced risk of CVD. The anti-inflammatory and cancer chemopreventive effects of raisins are mixed. Raisin consumption reduces intestinal transit time and positively affects gut microbiota. Raisins produce sustained energy during long term athletic competitions equal to traditional sports energy gels, shots and jelly beans. Raisins produce a non-cariogenic oral environment and do not fit the American Academy of Pediatrics criteria to be considered a choking hazard. Conclusions: Based on the review of literature, consumption of raisins provide numerous health benefits for promoting general wellness and in the prevention of many chronic diseases including: CVD, type 2 diabetes mellitus (T2DM) gastrointestinal diseases, and dental caries.

본 연구는 고지방식이 섭취시 RS섭취가 장기능 및 혈액지방성분에 미치는 영향을 알아보고자 하였다. 생후 4주된 실험동물을 구입하여 6주간 고지방식이로 사육하여 성장 시킨 후 RS함량이 다른 실험식이로 4주간 더 사육한 후 실험한 결과는 다음과 같다. 4주간의 실험식이를 섭취하였을 때 식이 섭취량과 식이효율은 실험군간의 차 가 없었고, 대조군에 비해 RS30군에서 체중과 부고환지방무게가 유의적이지는 않으나 감소하는 경향이었다. 소장과 대장의 길이, 맹장의 무게는 실험군간의 유의적인 차이가 없었다. 분변내 수분함량을 보면 RS를 30%섭취한 군에서 유의적이지는 않으나 증가하였고, 실험식이 섭취후 3주째 측정한 장통과시간은 RS 30군에서 감소하는 경향을 보였다. 대장세포의 증식은 RS30 군에서 유의적이지는 않으나 증가하는 경향을 보였다. RS섭취량에 따라 총지방량, 중성지방량은 유의적으로 감소하였으나 콜레스테롤과 HDL-콜레스테롤량은 실험군간에 차이가 없었다. 이상의 결과에서 고지방을 섭취한 성장이후의 쥐에서 RS섭취는 유의적 이지는 않으나 체중과 체내 저장지방, 장통과시간을 감소시키는 경향을 보였으며 , 혈액 내 총지방량과 중성지방량을 유의적으로 감소시켰다. 그러므로 난소화성전분의 섭취는 저열량원으로의 가능성을 보여주고 있으며 , 고지방식이시 혈액내 총지방량과 중성지방을 낮추는 효과가 있는 것으로 사료된다 그러나 이러한 효과는 dose dependent 하지는 않았으며 난소화성 전분을 식이무게의 30%로 섭취할 경우에 유의적으로 나타났다.
