The expression of HB-EGF (heparine binding epidermal growth factor) in cells of mice increased just after partial level removal in hapatectomy and reached maximal value 3 hours later. TGF-A expression in mice cells after 2/3 hepatectomy reduced in comparing with control in 3 first hours later and increased in 6 hours later

In Viet Nam, the method of liver resection developed by Prof. Ton That Tung at Viet Duc Hospital was approved worldwide. After that realisation liver trasplantation had been considered. In 1965 Ton That Tung and his collaborators had carried an experiment to graft total liver on dog and had preliminary success, afterwards human liver tranplantation began to prepare. In 2002, in Viet Duc hospital, 15 cases of experimental liver tranplantation were performed totally in pig to get experience and the results were encouraged. For implementing a first case of liver transplantation in late year 2003 and for developing this technique in some main institution in next time, some preparation must be started

The study was divided into 2 phases: In phase 1 (1997), the left lobes were removed and transplanted autogenously to other sites. Phase 2 (1998 - 2000) was performed according to the human liver transplantation model. Results: In phase 1, the left lobes were removed in 6 animals, 4 animals were transplanted autogenously at spleen holes. 3/4 grafts had good outcomes. One out of 4 grafts discoloured with poor circulation. In second phase, 23 animals were removed left lobes, 21/23 grafts met requirements, and 5/23 animals had complications and dead soon postoperation. 18/23 animals remained to be survival postoperation. Among liver-received pigs, 5 animals were dead perioperation. 14/18 grafts had good outcomes. 4/18 grafts discoloured. The average extra survival of liver-received pigs was 14.6 hours

PURPOSE: Healey divided segment IV of the live as the 'superior portion (IVa) ' and the 'inferior portion (IVb) '. On the contrary, Couinaud suggested that there was no useful purpose in dividing segment IV because of several reasons. Our goal is to evaluate the safety of the 'isolated IVb (inferior) resection of the liver' via performing the dissection of cadavers. METHODS: There were ten total cadavers. Cadaver dissection proceeded with respect to the Glissonian pedicle, the portal vein and the bile duct, respectively. The total number of Glissonian pedicles at segment IV was measured. The distance between the origins of the IVa and IVb branches was measured. Additional pedicles that were known to exist at segment IVa were also evaluated. RESULTS: The mean number of Glissonian pedicles in segment IV, IVa, and IVb was 5 (+/-1.3), 1.6 (+/-7), and 3.4 (+/-0.9), respectively. The mean distance between the origins of the IVa and IVb branches was 5.6 mm (+/-3.9 mm). Two of 10 cases had a very short distance between the origins that were considered as having common origin. Additional pedicles were identified at the Lt. main Glissonian pedicle in all the cases (8 cases: 1 each, 2 cases: 2 each). CONCLUSION: Considering the possible existence of a common origin of segment IVa and IVb Glissonian pedicles, there is the risk that the segment IVa will be injured during 'iso lated IVb resection'. Inevitable ligation of the additional pedicle of segment IVa from the Lt. main Glissonian pedicle can be made during the 'isolated IVb resection'. Therefore, we think that 'isolated IVb resection of the liver' can be safe only when the surgeon divides the branches of segment IVb with meticulous preservation of the IVa branches.

168 healthy livers from lead patients were studied. The results have shown that 4 basic anatomical forms of the right liver and 6 basic anatomical forms of left liver have been found. 36.9% of cases can be dissected the left hepatic vein. This finding can be applied for the liver transplantation and heapatectomy and plastic reconstruction of hepatic veins.

To study on 65 HBsAg positive mothers and 61 their newborns received differents dosages and types of hepatitis B vaccine at 0, 1, 2 months. HBeAg was detected in 25 (38.5%) mothers and all of them were HBV DNA positive. HBsAg and HBV DNA was detected in 19 (76%) and 23 (92%) respectively of the 25 cord blood from HBeAg positive mothers, while detected in 16 (40%) and 12 (30%) respectively of the 40 cord blood from HBeAg negative mothers. Testing at 6 months after completion of the vaccineation schedule, the failure risk (HBsAg positive) of vaccines for dosage of 2.5 g/ml is higher than others (5 g/ml and 10 g/ml). Hepatitis B vaccine with hepatitis B immune globulin or vaccine dosages of 5 and 10g alone may be recommended for high-risk neonates.
