RESUMO
OBJECTIVE: To observe the effects of Qingdan Capsule (QDC) and Yanggan Lidan Granule (YGLDG), two kinds of compound traditional Chinese herbal medicines, on biochemical parameters in guinea-pigs with pigment gallstones. METHODS: An animal model of pigment gallstones was established in male guinea-pigs by hypodermic injection of lincomycin. The guinea-pigs were randomly divided into blank control group, untreated group, QDC group and YGLDG group. There were 8 guinea-pigs in each group. After ten-day treatment, animals were sacrificed and sampled to calculate the rate of stone formation, total bilirubin (TB), unconjugated bilirubin (UCB) and Ca2+ density in bile of the four groups. RESULTS: In comparison with the untreated group, the rates of stone formation in the QDC and YGLDG groups were significantly decreased (P<0.01). TBIL, UCB and Ca2+ content of bile in both QDC and YGLD groups was also significantly decreased (P<0.05, P<0.01). CONCLUSION: QDC and YGLD have good effects on biochemical changes of animal model of pigment gallstone in reversing the lithogenesity of bile by reducing the content of TB, UCB and Ca2+, hence resulting in clinical treatment and prevention of pigment gallstone disease.
RESUMO
OBJECTIVE: To observe the effects of Shengqing Capsule (SQC), a compound of traditional Chinese herbal medicine, on biochemical parameters in C57BL/6J mice with cholesterol gallstone. METHODS: Thirty-eight C57BL/6J mice were randomly divided into normal control group (n=10), untreated group (n=15) and SQC group (n=13). Cholesterol gallstone was induced in mice of the latter two groups by feeding high cholesterol diet. Mice in the SQC group were intragastricly administered SQC 0.22 g/(kg.d). After 8-week treatment, animals were sacrificed and sampled to calculate the incidences of stone formation. The contents of serum cholesterols and Ca(2+), and the malonaldehyde (MDA) content and superoxide dismutase (SOD) activity in liver tissues were detected. RESULTS: The incidences of stone formation were 73.33% in untreated group, 0% in normal control group, and 23.08% in the SQC group. And the INCIDENCE in untreated group was significantly higher than those in the normal control group and the SQC group (P<0.01). Contents of serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the SQC group were lower than that in the untreated group (P<0.01), and high-density lipoprotein cholesterol (HDL-C) in the SQC group was higher than that in the untreated group (P<0.01). SQC could increase the SOD activity and decrease the MDA content in liver tissues, showing significant differences as compared with those in the untreated group (P<0.05). CONCLUSION: SQC can decrease the incidence of stone formation and improve the biochemical parameters, which may be one of the mechanisms in the treatment and prevention of cholesterol gallstone disease.
RESUMO
OBJECTIVE: To study the role of estrogen receptor (ER) and progesterone receptor (PR) in the formation of cholesterol calculus and investigate the effects of Shengqing Capsule (SQC), a Chinese patent herbal medicine with the function of soothing liver and draining gallbladder, on ER and PR expressions. METHODS: A total of 80 female guinea pigs were divided into normal control group, untreated group, ursodeoxycholic acid group (UDCA group) and SQC group. The cholesterol gallstone was induced by feeding the guinea pigs with high-fat lithogenic diet. SQC and UDCA were separately administered to the guinea pigs in the SQC group and UDCA group. After 7-week administration, all the animals were sacrificed to calculate the incidence of calculus formation and detect the expressions the ER and PR in the epithelial tissue of gallbladder by immunohistochemical method. RESULTS: Gallstone was cholesterol calculus detected by infrared spectrum. The incidence of calculus formation in the SQC group (27.78%) was significantly lower than that in the untreated group (81.25%) (X(2)=9.721 5, P=0.001 8). On the basis of Reiner standard, the expression distribution of ER and PR increased gradually from the normal control group through the SQC group and UDCA group to the untreated group. Except for the former two groups and the latter two groups, the differences between the other groups and UDCA group were statistically significant (P<0.05). Besides, the differences of positive expression rates between groups were statistically significant (P<0.05). CONCLUSION: Increased expressions of ER and PR are closely related to the formation of cholesterol stone. And Shengqing Capsule can down-regulate the expressions of ER and PR.
RESUMO
OBJECTIVE: To explore the mechanism of the inhibiting effects of recipe for dispersing stagnated liver qi to promote bile flow (Danshijing Tablets) on cholesterol gallstone formation and provide experimental evidence for its clinical application. METHODS: Eighty guinea pigs were randomly divided into 4 groups, which were normal control group, untreated group, ursodeoxycholic acid (UDCA)-treated group and Danshijing Tablets-treated group. The gallstones in guinea pigs were induced by high-cholesterol diet. UDCA and Danshijing Tablets were given orally to guinea pigs in the corresponding group respectively for seven weeks. Then the physical signs of the guinea pigs, the rates of gallstone formation and the histomorphological changes of the gallbladder were examined. RESULTS: The behavior of guinea pigs in the Danshijing Tablets-treated group was obviously improved and the rate of gallstone formation was significantly decreased as compared with those in both untreated and UDCA-treated groups (P<0.05). The inflammation reaction of mucous membrane in gallbladder was evidently reduced in the Danshijing Tablets-treated group and its morphological appearance turned to be approximately normal. CONCLUSION: Recipe for dispersing stagnated liver qi to promote bile flow may decrease gallstone formation. Its mechanism may be related to reducing pathologic changes in gallbladder tissues, which will reduce the damages of cholesterol to the smooth muscle in gallbladder and enhance the contractility of gallbladder.
