ABSTRACT
Objective To explore the effect of mesenteric lymphatic ligation on liver injury induced by severe acute pancreatitis. Methods 54 SD rats are randomly divided into sham-operation group (A), severe acute pancreatitis group (B) and severe acute pancreatitis and ligation group (C). Liver tissues were collected from each rat in 6, 12, and 24 h after ligation. Pathological changes in liver tissues were observed by haematoxylin and eosin staining. Levels of serum glutamic-pyruvic transaminase and glutamic oxalacetic transaminase were detected. Levels of TNF-α and IL-1 in liver homogenate were examined by enzyme linked immunosorbent assay. Results Under light microscopic examination, neutrophils and inflammatory exudate in hepatic lobule was increased as time prolonged in group B. Inflammation was reduced in group C as compared with group B.Levels of serum glutamic-pyruvic transaminase and glutamic oxalacetic transaminase were more significantly increased in groups B and C than in group A (P<0.05);while they were more significantly decreased in group C than in group B. Levels of TNF-αand IL-1 in liver homogenate were significantly increased in group B as compared with group A (P < 0.05); whereas they were more significantly decreased in group C than in group B at 24 h (P < 0.05). Conclusions Mesenteric lymphatic ligation can reduce liver injury in severe acute pancreatitis. Mesenteric lymphatic fluids may play an important role in severe acute pancreatitis.
ABSTRACT
Aim To investigate the effect of effective fraction of Xie-Xin decoction and their compatibilities(EFX)on NF-?B and I?B expression of lung injury rats induced by LPS.Methods Rats were pretreated for 4 days with total flavones(TFL),total free anthraquinones(TFA),total conjugated anthraquinones(TCA),the high(low)dose of compatibility of TFL and TCA(A high,A low),the compatibility of TFL and TCA(B)and dexamethasone respectively 4 days,then injected intravenously with LPS to induce lung injury.6 rats were sacrificed respectively in every group at 1,2,4 h after LPS administration,and the right middle of the lung was harvested at every time point,the expression of NF-?B and I?B was evaluated by Western blot.Results TFA、A high and Dex can inhibit the nuclear translocation of NF-?B at 1,2,4 h(P
ABSTRACT
Objective To investigate the preventive and therapeutic effects of Tiaozhi Baogan Capsule (TBC) on fatty liver in rats and to explore its therapeutic mechanism. Methods SD rat models of fatty liver were set up by feeding high fat diet. After the treatment of TBC, the general physical state, liver index (the ratio of liver weight with body weight) , hepatic pathological changes , blood biochemical indices were observed in model rats. Results TBC could obviously ameliorate liver pathological changes in model rats, relieve hepatic steatosis and hepatocellular necrosis, decrease the content of malondialdehyde( MDA) and increase the vitality of superoxide dismustase (SOD) in serum and liver, lower the content of total cholesterol (TC) and low- density lipoprotein (LDL) in serum and decreae the liver index (P
ABSTRACT
AIM: To study the effect and mechanism of Baogan Xiaoshi Capsule(BXC) (Rhizoma Coptidis,Fructus Evodiae,Rhizoma Alpiniae Officinarum,Rhizoma Cyperi ,Rhizowa Atractylodis Macro cephalae,Fructus Aurantii Immaturus,Fel Bovis) preventing lithogensis of pigment gallstones in guinea pigs. METHODS: Feeding guinea pigs on lithogenous diet,BXC was taken for 3 months at the same time.In the end,the gallstone formation rate,biochemical indicators and liver morphology were observed. RESULTS: The gallstone formation rate was 76.92% in model group,and in BXC group,at middle or upper dose,it was 25%,20% respectively.BXC could increase the concentration of conjugated dilirubin and glycocholic acid,and decrease that of unconjugated dilirubin,Ca~(2+) and H~+.It could weaken the activity of endogenous ?-Glucuronidase and Ca~(2+)Mg~(2+)-ATPase,and also could strengthen that of Na~(+)K~(+)-ATPase.It could improve the fatty degeneration of liver. CONCLUSION: The results show that BXC could prevent pigment gallstone formation and the fatty degeneration of liver.The mechanism may be that BXC can weaken the activity of ?-Glucuronidase and decrease [Ca~(2+)].
ABSTRACT
OBJECTIVE:To study the litholytic,bacteriostatic and spasmolytic effects of Baoganxiaoshi capsule(BXC) in vitro.METHODS:Observed the effects of BXC on human bile pigmental and cholesterol gallstone, bacteria, duodenum smooth muscle of rabbits in vitro.RESULTS:The litholytic concentration of 7.568,15.135 and 30.270g(crude drug)/ml solutions of BXC on human bile pigmental gallstone were 5.4mg,8.3 mg and 14.7 mg respectively,and on human bile cholesterol gallstone were 2.9mg,5.1 mg and 7.1 mg respectively.So BXC have the litholytic function of bile pigmental and cholesterol gallstone.It can strongly inhibit or sterilize staphylococcus aureus, enterococcus, diphtherial bacillus, hemo1ytic streptococcus, and the MICs were 23.65mg(crude drug)/ml ,23.65mg(crude drug)/ml,23.65mg(crude drug)/ml and 47.297mg(crude drug)/ml respectively, and all of the MBCs were 47.297mg(crude drug)/ml.It can inhibit or sterilize coliform,salmonella and pneumococcus, and all of the MICs were 378.375mg(crude drug)/ml, and all of the MBCs were 756.75mg(crude drug)/ml.5.3 414mg(crude drug)/ml solutions of BXC could obviously inhibit the average tension amplified,the frequency accelerated,and the activity increaced,on the duodenum smooth muscle induced by ach(P
