Attempts to generate radical anions of acrylonitrile and 2,6-dicyano-1,6-heptadiene were unsuccessful, providing additional evidence against a linear structure as a stable structure for 2,5-dicyano-1,5-hexadiene radical anion. The cyclization of the radical anion of the 2,5-dicyano-1,5-hexadiene is the first example of an electron-catalyzed Cope cyclization.

• Experimental Acute Necrotising Pancreatitis: Evaluation and Characterisation of a Model of Intraparenchymal Injection of Sodium Taurocholate in Rats
  作者：Haim Paran

  DOI：10.1080/110241500447308

  日期：2000.10.20

  ObjectivesTo evaluate a simple model that produces progressive dose dependent pancreatitis, by intraparenchymal injection of sodium taurocholate.DesignOpen laboratory study.SettingTeaching hospital, Israel.MaterialsForty eight Wistar rats.InterventionsSodium taurocholate was injected, 0.3 ml/100 g body weight, in concentrations of 5% and 10% into the pancreatic parenchyma of 32 Wistar rats, resulting in two distinct groups of severity. In 16 sham controls, saline was injected into the pancreas in similar fashion. Blood samples were withdrawn before, and 6, 24, 48, and 72 hours after induction of pancreatitis.ResultsSix hours after taurocholate injection, there was a sharp increase in the plasma activities of amylase, lipase, and lactate dehydrogenase (LDH). After 24 hours plasma activities of amylase and lipase decreased to near normal values while LDH remained slightly increased for 48 hours and decreased only after 72 hours. At 6 hours after the injection, interleukin-6 (IL-6) concentrations had increased slightly in the 5% group and decreased to the baseline values at 24 hours. In the 10% group, the increase in IL-6 values was significantly greater than in the 5% group (p = 0.04), and correlated well with severity of pancreatitis as defined by histology (p = 0.01) and mortality (p = 0.037). Twenty four hours after injection of taurocholate, morphological changes comprising diffuse necrosis of the pancreas, fat necrosis, and intestinal dilatation secondary to paralytic ileus were severe. Histopathological examination of the pancreas showed good correlation with the clinical findings and with mortality.No morphological changes were detected when saline was injected into the pancreas (sham control), and only mild rises of IL-6, lipase, amylase, and LDH activities were seen at 6 hours after injection. The mortality, after 10 days, was 80% in the 10% taurocholate group, 30% in the 5% taurocholate group, and 0 in the sham control group (p < 0.05).ConclusionThe intraparenchymal injection of taurocholate is easy to perform and highly reproducible. The histopathological injury is dose-dependent, as is the mortality. We conclude that this model is valuable for the study of new treatments for pancreatitis.

  干预措施向 32 只 Wistar 大鼠的胰腺实质注射浓度为 5% 和 10% 的牛磺胆酸钠，每 100 克体重注射 0.3 毫升，结果分为两组不同的严重程度。在 16 个假对照组中，以类似方式向胰腺注射生理盐水。结果注射牛磺胆酸钠 6 小时后，血浆中淀粉酶、脂肪酶和乳酸脱氢酶（LDH）的活性急剧上升。24 小时后，血浆中淀粉酶和脂肪酶的活性降至接近正常值，而 LDH 在 48 小时内仍略有升高，72 小时后才有所下降。注射后 6 小时，5% 组的白细胞介素-6（IL-6）浓度略有上升，24 小时后降至基线值。在10%组中，IL-6值的增加明显高于5%组（p = 0.04），并且与组织学定义的胰腺炎严重程度（p = 0.01）和死亡率（p = 0.037）密切相关。注射牛磺胆酸钠 24 小时后，胰腺弥漫性坏死、脂肪坏死和肠扩张等形态学变化严重，继发于麻痹性回肠。向胰腺注射生理盐水（假对照）时未发现形态学变化，注射后 6 小时仅发现 IL-6、脂肪酶、淀粉酶和 LDH 活性轻度升高。10 天后，10% 牛磺胆酸盐组的死亡率为 80%，5% 牛磺胆酸盐组为 30%，假对照组为 0（P < 0.05）。组织病理学损伤与死亡率一样，都与剂量有关。我们认为，该模型对研究胰腺炎的新疗法很有价值。

  The thermal cycloisomerization of the 1,3-hexadiene-5-ynes 1a–e has been studied at temperatures above 500°C and reaction times of about 0.3 s (1a–d) and at a pressure of 1.5 · 10−2 Torr (FVP, 1e), respectively, at low partial pressures in quartz flow systems. While 1a and 1b cycloisomerize exclusively to the corresponding benzenes and pentafulvenes, substrates 1c–e cyclize primarily to 4-substituted
