嗜铬细胞瘤患者围手术期处理的改进

目的：探讨提高嗜铬细胞瘤患者围手术期安全性的措施。方法：对15例嗜铬细胞瘤患者、术前采用选择性α1受体阻滞剂多沙唑嗪控释片(可多华)控制高血压；11例患者采用3D DCEMRA进行肿瘤定位；术中均采用联合高容量血液稀释(AHH)和术中患者自体血回输纠正血容量。结果：除1例持续性高血压患者需联合钙离子拮抗剂和ACEI药物降压外．其余患者血压控制均为满意；根据3D DCEMRA定位选择手术径路者均顺利完成手术；AHH联合术中自体血回输使14例患者避免了异体输血。结论：本文围手术期处理改进．可多华可明显减少药物的不良反应；采用3D DCEMRA进行肿瘤定位，可增加手术安全性；AHH联合术中自体血回输可减少医疗成本和异体输血，以及由此而引起的并发症。

Role of endothelin in the pathogenesis of hypertension in spontaneously hypertensive and 2 kidneys 1 clip rats.

The plasma endothelin (ET) level in spontaneously hypertensive rats (SHR) and 2K1C hypertension animal models and its vasoconstrictive effect on renal and tail arteries were studied. The results demonstrated that there was no difference in plasma ET level between the hypertensive groups SHR, 2K1C, normotensive control groups Wistar Kyot (WKY) and Sprague Dawley (SD), while the vasoconstrictive effect of ET in SHR was more dominant than in WKY. The EC50 of the renal and tail arteries in SHR (0.8912 +/- 0.1662 x 10(-8) M, 0.6103 +/- 0.0878 x 10(-8) M) was apparently lower than that in WKY (1.77 +/- 0.2991 x 10(-8) M, 1.2267 +/- 0.2502 x 10(-8) M, P less than 0.05), but no difference was found in 2K1C and SD rats. The four groups of animals exhibited no difference of such effects as response to norepine-phrine (NA). The findings suggested that the increased arteriole sensitivity to ET be an important factor in the pathogenesis of hypertension in SHR.

Changes of Intestinal Caicitonin Gene-related Peptide in Acute Intestinal Radiation Sickness in Rats

The characteristic distribution of calcitonin gone-related peptide(CGRP)inthe small intestine of rats and its changes in acute intestinal radiation sickness(AIRS)were studied with immunocytochemistry(whole mount stretch preparations of the smallintestine and cryostat sections)and radio-immunoassay.It was found that in all the lay-ers of the intestinal walls,there were large amounts of CGRP immunoreactive(CGRP-I)nerve fibers which existed in especiaUy high density in the myenteric,submucosal andmucosal plexuses.There was also a rather high density of the nerves around the smallvessels of the small intestine and the intestinal crypts.Some CGRP-I neurons were seenin the myenteric and submucosal plexuses.In AIRS,the intestinal CGRP showed a dip-hasic change,in a lower level in the 24th h and a higher level in the 48th and 72nd h af-ter irradiation.The results indicate that CGRP may be related to the regulation of the motility,se-cretion,absorption,sensation,and regional blood flow of the gastrointestinal tract.Pro-bably,CGRP is released under the stress of AIRS and participates in the mechanism ofinjury through many ways especially through the influence on the regional blood flowand the increase of the permeability of blood vessels.     

单核吞噬细胞应答伤寒沙门菌的实验研究

目的 研究单核吞噬细胞应答伤寒沙门菌的机理。方法 采用体外培养的PMA分化的THP－1细胞，检测其内化和杀伤胞内伤寒沙门菌的活性，以及伤寒沙门菌诱导PMA分化的THP－1细胞产生TNF－α和IL－12的情况。结果 PMA分化的THP－1细胞内化和杀伤Vi阴性伤寒沙门菌的活性明显高于内化和杀伤Vi阳性伤寒沙门菌的活性。IFN－γ明显中此活性。伤寒沙门菌诱导PMA分化的THP－1细胞可以产生一定量的TNF－α和IL－12，然而，IFN－γ活化的PMA分化的HTP－1细胞产生TNF－α和IL－12的量明显增加。结论 伤寒沙门菌在单核吞噬细胞中的存活可能与Vi抗原的存在有关；IFN－γ在调节机体细胞免疫，防循伤寒沙门菌感染中起着重要的作用。
