Comparison of rat liver preservation with Eurocollins and a modified University of Wisconsin solution: transplantation and isolation of hepatocytes for culture

The efficiency of Eurocollins or modified University of Wisconsin (UW) solution (MUW) in preserving rat livers was compared. After cold storage with one of the solutions, the livers were transplanted or perfused by collagenase for isolation of hepatocytes. Five of the 6 rats receiving a graft preserved with MUW versus none of the 6 rat receiving a graft preserved with Eurocollins solution survived 24 h or more. A significantly greater number of hepatocytes were isolated from livers preserved with MUW than from livers preserved with Eurocollins solution. This suggests a better reperfusion of MUW-preserved livers by collagenase resulting from less endothelial injury. LDH release by cultured hepatocytes, ketone body production and stimulation by glucagon were not significantly different between the two groups. These results confirm the superiority of MUW solution over Eurocollins in preserving liver grafts. They suggest that the advantage of MUW solution results from better protection of vascular endothelium rather than of hepatocytes.     

HLA-DPB1 gene polymorphism and multiple sclerosis: a large case-control study in the southwest of France

The polymorphism at the HLA-DPB1 locus has been characterized in a large number of patients with multiple sclerosis (n = 112) and in healthy controls (n = 115). Both patients and controls lived in the southwest of France (in the Pyrénées Atlantiques) and had similar ethnic background. The typing procedure involved the selective amplification of the second exon of the DPB1 locus by polymerase chain reaction, followed by hybridization of the amplified DNA with 14 sequence-specific oligonucleotide probes. Individual alleles were identified by the pattern of hybridization of the different probes. The distribution of the DPB1 alleles was not significantly different in multiple sclerosis patients and controls (p = 0.11). This does not corroborate the reported association of multiple sclerosis with the primed lymphocyte typing (PLT)-defined DPw4 specificity and is not in favour of a role played by polymorphic residues of the DP molecule in susceptibility to multiple sclerosis.     

West Nile virus quantification in feces of experimentally infected American and fish crows.

To better understand the potential environmental health risk presented by West Nile virus (WNV)-contaminated feces, we quantified the amount of WNV present in the feces of experimentally infected American crows (Corvus brachyrhynchos) and fish crows (Corvus ossifragus). Peak fecal titers ranged from 10(3.5) to 10(8.8) plaque-forming units (PFU)/g for 10 American crows and from 10(2.3) to 10(6.4) PFU/g for 10 fish crows. The presence of infectious WNV in bird feces indicates a potential for direct transmission of WNV. Thus, handlers of sick or dead birds should take appropriate precautions to avoid exposure to fecal material.     

腔内聚乙烯十二指肠-空肠导管对体重调节的作用:猪动物模型可行性研究

目的评估十二指肠-空肠导管（Endoluminal Duodeno-Jejunal Tube，EDJT）在活体猪实验动物模型中减缓体重增加的可行性，及其在中短期生存中的安全性。方法本项研究共用8只45kg重的Yorkshire猪，其中3只置入180emEDJT，1只置入360cm EDJT，另4只猪作为对照组。切开十二指肠，将EDJT导管缝合固定在十二指肠近Vater壶腹起始处。结果评估全部猪的不适反应和体重，每日一次，共7周，未发现严重并发症发生。术后7周3组动物的平均体重变化百分率：对照组、180cm组和360cm组分别是22．5％，6％和-2．8％。EDJT组（180cm组、360cm组）体重增加明显减慢，与对照组相比，有统计学意义（P=0．05）。结论EDJT可以安全使用，无肠梗阻、肠套叠或胰腺炎等并发症发生。EDJT可明显减缓体重增加。
