Results: MR demonstrated capsule wall and papillary solid lesions in one case with cystic and solid lesions of hepatobiliary cystadenoma. Poly cystic form tan if different sine in sew case, capsule wall and septation was thick, part of capsule wall was obviously thickened and nodes form, intrahepatic bile duct was dilated, large poly-antrum cystic keen form structure in one case, capsule wall and septation were smooth, part of capsule wall was uniformly thicken, capsule wall, septation, mural nodus form and solid lesions in three cases wee all slightly hyperintense on T2WI and slightly hypointense on T1WI. Part of cyst fluid was hypointense on T2WI the diameter if tumor ranged from 3.4cm to 13.5cm. Part of capsule wall, septation, solid lesions and mural nodus west obviously enhanced in arterial phase in three cases, the extent of enhancement showed a little degrade in port vein phase, balance phase and delay phase, but dense to liver parenchyma at synchronization.

IL-1βmRNA expression in the developmental brain in Wistar rat: IL-1β mRNA in hippocampus, cerebral cortex and subcortex was detected by postnatal day 1 and gradually increased with development, reached a peak at postnatal day 21, and then gradually decreased to lower level at adult; In P77PMC rat, IL-1β mRNA expression was similar to Wistar rat before postnatal day 14, then gradually increased and surpassed Wistar rat at postnatal day 28, reached a peak in adult.
原位杂交显示谷氨酸诱导Wistar大鼠惊厥和P77PMC大鼠听源性惊厥后脑内IL-1βmRNA表达情况。结果发现,两种不同惊厥模型大鼠惊厥后脑内IL-1βmRNA表达存在明显的差异。谷氨酸引起惊厥诱导脑内皮层、海马和丘脑IL-1βmRNA表达增高的程度远较P77PMC大鼠听源性惊厥为低,而且惊厥后IL-1βmRNA表达增加较慢,于4-8h达高峰,而听源性惊厥可于惊厥后2h迅速达高峰。但两种形式惊厥诱导脑内IL-1βmRNA表达最高的部位均是海马。
