Some thermodynamic parnmeters of Pd-In alloys with 2 to 70 at. H indium have been determined in the temperuture range 800 to 1000℃ from e.m.f measurements ongalvanic cells with an onsen-cotzducting solid electrolyte. Heats of tnising calculated hem the activities are in excellent agreement with calorimetric data. The relative partial excess hee enengy of indiurn assumes unnsually larpe negative values ap to-174kJ/mol for Pd-rich alloys. Two efficts are discussed to account for the non-idealproperties: The rise Of Fermi enerpy as the valence electron8 of indium enter the 4dand 5sP bands of the alloy and the lattice distortion brought about by the differentmolar volumes of the cofnponents. The rise of the Fermi enerpy, as determlned fromthe activity data, indicates a strict adherence of the alloys to the rigid band model.

BACKGROUND: Liver revascularization is frequently required during the enlarged radical operation for hilar cholangio carcinoma involving the hepatic artery. Researchers have carried out a number of experiments applying partial porta vein arterialization (PVA) in clinical practice. In this study we aimed to establish a theoretical basis for clinical application o partial PVA and to investigate the effects of partial PVA on ra hilar bile duct and hepatic functions. METHODS: Thirty rats were randomly and equally assigned into 3 groups: control (group A), hepatic artery ligation+bile duct recanalization (group B), and partial PVA+bile duc recanalization (group C). Proliferation and apoptosis o rat hilar bile duct epithelial cells, arteriolar counts of the peribiliary plexus (PBP) of the bile duct wall, changes in serum biochemistry, and pathologic changes in the bile duc were assessed 1 month after operation. RESULTS: The proliferation of hilar bile duct epithelial cells in group B was greater than in groups A and C (P0.05), but the coun was lower in group B than in group A (Pyltransferase value was higher in group B than in groups A and C (P<0.01) The hepatic tissues of groups A and C showed no significan abnormality. Chronic inflammatory changes in the hilar bile duct walls were observed only in group B. CONCLUSION: Partial PVA can restore the arterial blood supply of the hilar bile duct and significantly extenuate the injury to hilar bile duct epithelial cells resulting from hepatic artery ligation.

目的:观察延迟复苏大鼠远隔脏器的能量代谢情况。方法:实验于2001-05/2004-08在长海医院烧伤中心实验室完成。取24只SD大鼠随机分为假烫组、烧伤组、早期复苏组、延迟复苏组4组,每组6只。①除假烫组外,其他3组大鼠用恒温水烫仪100℃水烫12s,制成体表面积30%Ⅲ度烧伤模型(病理证实),假烫组于37℃水中假烫12s。②伤后假烫组和烧伤组不液体复苏,早期复苏组在伤后30,90min分别用30mL/kg乳酸林格氏液腹腔注射液体复苏;延迟复苏组大鼠在伤后6,7h分别用40mL/kg乳酸林格氏液腹腔注射液体复苏。③所有大鼠伤后9h取材,测定肺、心、肝、肾组织Na+-K+-ATP酶活性,Ca2+-Mg2+-ATP酶活性,髓过氧化物酶活性,一氧化氮代谢产物量。结果:24只大鼠进入结果分析。①烧伤后9h延迟复苏组大鼠肺、心、肝、肾组织的Na+-K+-ATP酶活性分别为(0.16±0.03),(2.82±0.41),(1.96±0.29),(3.94±0.40)μkat/g,明显低于烧伤组和烧伤后早期复苏组(P<0.05或0.01)。②烧伤后9h延迟复苏组大鼠肺、心、肝、肾组织的Ca2+-Mg2+-ATP酶活性分别为(0.40±0.08),(3.71±0.70),(2.44±0.56),(2.39±0.57)μkat/g,也明显低于烧伤组和烧伤后早期复苏组(P<0.05或0.01)。③烧伤后9h延迟复苏组大鼠肺、心、肝、肾组织的髓过氧化物酶活性分别为(9.91±1.13),(0.80±0.09),(0.75±0.08),(0.76±0.09)μkat/g,明显高于烧伤组和烧伤后早期复苏组(P<0.05或0.01)。④烧伤后9h延迟复苏组大鼠肺、心、肝、肾组织中一氧化氮代谢产物量明显少于烧伤组和烧伤后早期复苏组(P<0.01)。结论:烧伤延迟复苏大鼠远隔脏器存在能量代谢紊乱,中性粒细胞积聚和一氧化氮产生减少可能是其重要机制。
