The objective of this study was to evaluate the effects of Lactobacillus acidophilus ATCC 43121 and L. fermentum MF27 on biochemical indices in the serum, cholesterol metabolism in the liver and mucin expression in the gallbladder in lithogenic diet (LD)-induced C57BL/6J mice to determine the preventive effects of lactobacilli on gallstone formation. By the end of 4 wk of the experimental period, mice fed on a LD with high-fat and high-cholesterol exhibited higher levels of total and low-density lipoprotein cholesterol in the serum compared to mice fed on control diet or LD with L. acidophilus ATCC 43121 (LD+P1; p<0.05). Cholesterol-lowering effects observed in the LD+P1 and LD with L. fermentum MF27 (LD+P2) groups were associated with reduced expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase in the liver compared to the LD group (p<0.05). Furthermore, expression of the gel-forming mucin, including MUC5AB and MUC5B, was suppressed in the LD+P1 and LD+P2 groups compared to the LD group (p<0.05). Therefore, steady intake of both L. acidophilus ATCC 43121 and L. fermentum MF27 may have the ability to prevent the formation of cholesterol gallstones in LD-induced C57BL/6J mice.

Gallstone diseases appear frequently in surgical patients. One of the etiolic factors in the formation of cholesterol gallstones is the supersaturation of bile with cholesterol. The bile stasis in the gallbladder may also play a role in the formation of cholesterol gallstones by supplying the proper condition to nucleation of cholesterol crystal. Author evaluated gallbladder empting in response to fat meal by ultrasonography in 12 patients with gallstones and normal control group of 12 healthy subjects. Of the 12 patients with gallstones, six had radiolucent stones and the rest of them had radioopaque stones. Additionally, author evaluated gallbladder contraction in both cholesterol gallstones and pigment gallstones. The gallbladder was significantly contracted in control group by the fat meal but not by water. The contraction of gallbladder by fat meal with gallstone patients was significantly decreased compared with those in control group. The time of maximum contraction was 30 minutes in patients with gallstones. At 30 minutes, the gallbladder contraction was more significantly decreased in patients with radiolucent stones than in those with radioopaque stones. In conclusion, the more significant decrease of gallbladder contraction in patients with radiolucent stones may be interpretated as the possible factor of pathologenesis for the formation of the cholesterol stone.

Gallstone composition has changed over the past decades in the Korean with a prominent increase in the prevalence of cholesterol gallstone. This trend is possibly due to the westernization of dietary habits. The purpose of this study was descriptive of GB patient's health related eating behaviors and nutrient consumption patterns. One hundred and six gallstone patients who have had cholecystitis surgery enrolled in this study. Anthropomertic indices, such as height, weight, waist circumference, and hip circumference were measured and calculated BMI and WHR. As the biomarker, TC, TG, LDL-C, HDL-C, FBG level and SBP/DBP were measured and analyzed the relationship with GB stone formation. The structured checklist of health related eating behavior and the semiquantitative food frequency questionnaire after pre-test was used in the face to face interview study. The mean age was $54.9{\pm}13.3$ and gallstone disease was more frequent in the fifties and sixties. Mean BMI was $24.3{\pm}2.8$ in males, and $23.4{\pm}3.9$ in females, the average of waist circumference was $91.1{\pm}7.0cm$ in males and females were $85.4{\pm}9.6cm$. The WHR of men and women was $0.93{\pm}0.0,\;0.90{\pm}0.1$, respectively. The obesity and overweight trend was observed in gallstone patients. The mean blood sugar was researched at $114.5{\pm}35.0mg/dL$. And the ratio of both symptoms DM and gallstone was 26.4%. The rate of dramatic eating repast was significantly higher in the females (p<0.01). Males tended to more frequently consume meat, of high fat content meats and greasy food consumption when eating out. The CPF ratio was 57:16.5:26.5. There was a significant positive correlation between WC and energy (r=0.252, p<0.05), carbohydrate (r=0.255, p<0.05) and niacin (r=0.227, p<0.05). In addition, carbohydrate were significantly correlatied with TC (r=0.230, p<0.05). BMI appeared positive in correlation of protein (r=0.201, p<0.05) and fat (r=0.205, p<0.05). These findings provide a little association that dietary habits are related with cholesterol gallstone formation.

A method to discriminate human gallstones by nea. infrared(NIR) spectrometry using a soft independent modeling of class analogy (SIMCA) has been studied. The fifty NIR spectra of gallstones in the wavenumber range from 4500 to 10,000 cm$\^$-1/ were measured. The forty samples were classified to three classes, cholesterol stone, calcium bilirubinate stone and calcium carbonate stone according to the contents of major components in each gallstone. The training set which contained objects of the different known class was constructed using forty NIR spectra and the test set was made with ten different gallstone spectra. The number of important principal components(PCs) to describe the class was determined by cross validation in order to improve the decision criterion of the SIMCA for the training set. The score plots of the class training set whose objects belong to the other classes were inspected. The critical distance of each class was computed using both the Euclidean distance and the Mahalanobis distance at a proper level of significance(${\alpha}$). Two methods were compared with respect to classification and their robustness towards the number of PCs selected to describe different classes.

With changes in human dietary patterns, the proportion of high-fat and high-cholesterol foods in the daily diet has increased. As a result, the incidence rate of cholelithiasis is increasing rapidly. Many studies have reported on the crucial role that the intestinal microflora plays in the progression of gallstones. Although the whole herb of Lysimachia christinae, a traditional Chinese medicine, has long been extensively used as a remedy for cholelithiasis in China, its effects on the intestinal microflora remain unknown. Hence, in this study, we investigated the ability of the aqueous extract of L. christinae (LAE) to prevent cholesterol gallstones (CGSs) in model animals by affecting the intestinal microflora. The effects of LAE on body weight, serum lipid profile, visceral organ indexes, and histomorphology were studied in male C57BL/6J mice, which were induced by a lithogenic diet. After the 8-week study, CGSs formation was greatly reduced after LAE treatment. LAE also reduced body weight gain and hyperlipidemia and restored the histomorphological changes. Moreover, the intestinal microflora exhibited significant variation. In the model group fed the lithogenic diet, the abundances of the genera unclassified Porphyromonadaceae, Lactobacillus and Alloprevotella decreased, but in contrast, Akkermansia dramatically increased compared with the control check group, which was fed a normal diet; the administration of LAE reversed these changes. These results imply that L. christinae can be considered an efficient therapy for eliminating CGSs induced by a high-fat and high-cholesterol diet, which may be achieved by influencing the intestinal microflora.

담석은 담도계의 가장 흔한 질환으로 최근 우리나라에서 콜레스테롤 담석의 비율이 증가하고 있으며 그 대표적인 위험인자로는 연령, 여성, 비만 등이 거론되고 있다. 본 연구는 건강검진자를 대상으로 최근 3년간의 담석의 유병률 및 위험인자를 알아보고자 하였다. 2011년 1월에서 2013년 12월까지 대구지역 종합검진전문병원에서 건강검진을 받은 4,696명을 대상으로 성별과 연령별 분표를 조사하고 키와 몸무게, 공복혈당과 간기능 및 기본 지질 검사를 하였고, 초음파 검사를 통해 담낭의 담석을 진단하였다. 체질량 지수에 따라 저체중, 정상체중, 과다체중, 비만 집단으로 나누었고, 공복혈당 수치는 미국 당뇨 협회에서 제시한 당뇨병의 진단 기준에 따라 분류하였다. 간기능 수치는 본원에서 사용하는 간기능 정상치를 참조하여 대상군을 나누고 지질 수치는 NCEP APTIII에 따라 분류하였다. 분석결과 담석이 발견된 경우는 148명(3.15%)으로 남자 84명(1.79%), 여자 64명(1.36%)으로 남자에서 더 높았으나 성별 간 유병률은 차이는 없었다. 연령별 유병률은 40대 이하 1.84%, 40대 3.38%, 50대 이상 4.66%로 담석이 없는 집단에 비해서 유의하게 높았다(p<0.003). 또한 담낭 담석으로 판명된 대상자의 신체검사 상 고지혈분류 항목에서 비정상군은 Total-cholesterol 52명으로 가장 많았고, LDL-cholesterol 39명, Triglyceride가 36명, HDL-cholesterol 19명이였다. 단변량 분석을 시행한 결과 연령, 공복혈당, 체질량지수는 담석의 유병률과 의미 있는 상관관계를 보였고, 다중 로지스틱 회귀분석에서도 연령, 체질량지수가 담석증의 독립적인 위험인자로 선정되었다. 결론적으로 비록 담석이 대사증후군과의 관계에서 나타나지 않았지만 이를 규명하기 위해서는 건강검진 대상자뿐만 아니라 일반 국민을 대상으로 한 추가적인 연구가 필요하다고 사료된다.

Purpose: We investigated the clinical features and factors affecting the choice of treatment modality and the course of pediatric gallstone (GS) disease. Methods: We retrospectively analyzed the medical records of 65 patients diagnosed with GS using imaging studies between January 2009 and December 2017 were included. Results: This study included 65 patients (33 boys and 32 girls; mean age, 8.5±5.3 years; range, 0.2-18 years) who primarily presented with abdominal pain (34%), jaundice (18%), and vomiting (8%). Idiopathic GS occurred in 36 patients (55.4%). The risk factors for GS included antibiotic use, obesity, hemolytic disease, and chemotherapy in 8 (12.3%), 7 (10.8%), 6 (9.2%), and 4 patients (6.2%), respectively. We observed multiple stones (including sandy stones) in 31 patients (47.7%), a single stone in 17 (26.2%), and several stones in 17 (26.2%). GS with a diameter of <5 mm occurred in 45 patients (69.2%). Comorbidities included hepatitis, choledocholithiasis, cholecystitis, and acute pancreatitis in 20 (30.8%), 11 (16.9%), 11 (16.9%), and 4 patients (6.2%), respectively. Ursodeoxycholic acid (UDCA) was administered to 54 patients (83.1%), leading to stone dissolution in 22 patients (33.8%) within 6 months. Cholecystectomy was performed in 18 patients (27.7%) (mean age, 11.9±5.1 years). Most patients treated surgically had multiple stones (83%) and stones measuring <5 mm in size (89%), and 66.7% of patients had cholesterol stones. Conclusion: Cholecystectomy is feasible in patients with small-sized or large numbers of GS and those with persistent abdominal pain and/or jaundice. UDCA administration with close follow-up is recommended in patients with uncomplicated GS.

담즙내 지방산의 농도와 그 조성이 콜레스테롤의 과포화와 마찬가지로 담석 형성 과정에 관련이 있는 것으로 여겨지고 있다. 본 연구에서는 gas chromatography-mass spectrometry (GC-MS)의 selected ion monitoring (SIM) 방법을 이용하여 담즙내 23종의 지방산 동시 분석을 시도하였다. 전처리 과정의 첫 단계로 유리 지방산과 인지질 지방산을 분리하기 위해 aminopropyl column을 사용하였고 GC-MS에서의 검출을 위하여 유리 지방산은 MSTFA/TMCS 혼합액으로 유도제화를 실시하였으며 인지질 지방산의 경우는 염기를 이용한 가수분해를 실시한 뒤 위와 동일한 과정으로 유도제화하였다. 이 때의 회수율은 61.1-99.0% 이었으며 각각 3.1-25.6%와 3.8-27.0%의 within-a-day와 day-to-day 분석의 RSD 값을 얻었다. 이 방법을 적용하여 정상인과 담석증 환자의 담즙내에 존재하는 유리 및 인지질 지방산의 농도를 알아보았으며 이 때 각 물질들의 농도와 분포가 두 군간에 차이를 나타냄을 알 수 있었다.
