ABSTRACT
Objective To observe the expression and distribution of myofibroblasts in the healing process of bile duct and discuss its function and significance in the process of iatrogenic biliary stricture formation. Methods A model of trauma-repair of bile duct in the dog was made . The anastomosis tissues on week 1,3 and month 3,6 after operation were studied with TEM and immunohistochemical SP staining of SMA. Results Myofibroblasts functioned actively and lasted for the whole process, extracellular matrix overdeposited. SMA staining was observed in myofibroblasts and highly expressed from 1 week to 6 months after operation. The consequence easily leaded to scar contracture and anastomoctic stenosis. Conclusion Myofibroblast is the main cause of scar contracture of bile duct.
ABSTRACT
Objective To study the correlation between splenic macrophage (M?) phagocytosis and peripheral blood cell count in cirrhotic portal hypertensive (CPH) patients Methods Spleen M? phagocytosis was measured in 20 CPH patients with hypersplenism and 6 patients with traumatic spleen rupture Results The M? phagocytosis rate in CPH patients was (12 6?3 0)% compared with (6 9?0 5)% in traumatic patients ( P
ABSTRACT
Baicalein is an important component of traditional Chinese herb, Scutellariae Radix(Huang Qin), and has various efficacies, including anti bacterial, antivirus, anti inflammation, protecting the liver function, diuresis, anti tumor, and shows good values in clinical application. It was majorly applied to acute or chronic inflammation. This article reviews developments in its pharmacological action and mechanism and provides theoretical evidences for exploiting of baicalein.
ABSTRACT
The vein s near the cardiac area of the stomach were studies in 60 cases of Chines cadavers (26 adults, 34 children). The main results are as follows: The coronary vein (lefe gastric) may be divided into 3 types. Type Ⅰ (2 branches) was found in 55 cases (91.66%.t In 33 cases (55.00%), the gastropancreatic fold was situated on the left side of the vertebral colum, and it ended in the splenic vein in 36 cases (60.00%). The average diameter at its terminal end was 3.81 (2.0-6.0) mm. The cardioesophageal branch may be classified into 2 types. Type Ⅰ (1 branch) was found most frequently in 55 cases (93.22%), and it ended in the arched portion of the coronary vein in 55 cases (87.30%). The right gastric vein (pylorus) opened into the portal vein in 49 cases (89.09%). The posterior gastric vein may be divided into 2 types. Type Ⅰ (1 branch) occurred in 45 cases (90.00%). The end of this vein was located in the mid-third of the splenic vein in 41 cases (74.55%). Short gastric veins two to six branches in number, among which three or four branches were most frequently observed.
