Objective To develop an advanced two-cuff technique orthotopic liver transplantation model in rats. Methods On the basis of the previous two-cuff-technique, some hypercoagulable blood was released from the recipient's PV and IVC before the cuffed donor PV and IVC were inserted into the lumen of the recipient's PV and IVC. The anastomosis of recipient's SVC was between the donor's diaphragm venaccaval hiatus and recipient's SVC. Results Every anastomosis was effective. The operative successful rate and one-week survival rate were 96.7?% and 90.0?% respectively. Conclusion This model could be used as an effective measure for the study of liver transplantation in rats.

Objective To investigate the protective effects of transection of the cervical sympathetic trunk (TCST) on the gastric mucosal lesions in rats fastened to a board and immersed vertically in water, up to the level of xiphoid with the animals' heads up water for 6 hours. Methods Thirty male SD rats weighing 200-250 g were randomly divided into 3 groups ( n = 10 each): group A sham operation; group B sham operation + water immersion and group C TCST + water immersion. The animals were anesthetized with intraperitoneal 2.5% pentobarbital 40 mg?kg-1. Cervical sympathetic trunk was exposed at right common carotid artery bifurcation and cut. The gastric mucosal blood flow (GMBF) was measured with Doppler blood flow monitor after 6 h water immersion. Blood samples were taken from abdominal aorta for determination of plasma concentration of ET-1 and serum concentration of NO. Gastric mucosal ulcer index was determined according to Guth criteria.Results There was gastric mucosa bleeding and erosion in group B and C and the degree of injury was severer in group B than in group C. Plasma concentration of ET-1 and serum concentration of NO were significantly higher in group B than in group C and A.Conclusion TCST has protective effect on gastric mucosal blood flow in rats under stress by reducing blood ET and NO concentrations.

Objective To investigate the effect of hypoxia adaptation on cerebral ischemai hypoxic injury Methods Hypoxia pretreatment mouse was placed in a tightly closed 150 ml bottle with large opening Once the mouse developed dyspnea, it was taken out and placed in another tightly closed 150ml bottle filled with fresh air When the mouse was short of breath it was again taken out This process was repeated 4 times Ischemia hypoxia model the left common carotid artery was ligated under ether anethesia and 1h later the mouse was placed in a hypoxia chamber in which the oxygen concentration was maintained at 8% Twenty four Kunmin mice weighting 18 25g were divided into six groups of four animals each:(1) control group; (2) hypoxia pretreatment group; (3) ischemia hypoxia group I (group I H1): the mice stayed in hypoxia chamber for 1 h; (4) ischemia hypoxia group 2 (group I H2): the mice stayed in hypoxia chamber for 2h; (5) hypoxia pretreatment +I H1; (6) Hypoxia pretreatment +I H2 The animals were sacrificed immediately at the end of the experiment Neural apoptosis was identified by terminal deoxynucleotidyl transferase mediated dUPT biotin nick end labelling (TUNEL).Results Apoptosis cells could be seen scattered in the cerebral cortex in hypoxia adaptation group and group I H1 No apoptosis cells were found in control group and group I H2 But hypoxia adaptation increased the number of apoptosis cells in severe hypoxia ischemia group (group I H2) Conclusions Hypoxia adaptation protects brain against hypoxia ischemia injury Hypoxia adaptation induces apoptosis Hypoxia adaptation can have neurons end up in apoptosis instead of nacrosis during cerebral ischemia hypoxia
