Serotonergic projections from the midbrain periaqueductal gray and nucleus raphe dorsalis to the nucleus parafasccicularis of the thalamus

By a double-labeling method combining the retrograde tracing of horseradish peroxidase and the immunocytochemical technique, serotonin-like immunoreactive neurons in the midbrain periaqueductal gray (PAG) and nucleus raphe dorsalis (DR) of the rat were observed to send projection fibers to the nucleus parafascicularis of the thalamus bilaterally with an ipsilateral dominance. These serotonin-containing projecting neurons were observed mainly at the middle-caudal levels of the ventrolateral subdivision of the PAG and less at the middle-rostral levels of the DR.

Segmental hyperintensity on T1-weighted MRI of the liver: Indication of segmental cholestasis

The purpose of this study was to determine the relationship between segmental hyperintensity of the liver on T1-weighted images and segmental cholestasis in patients with obstructive jaundice. T1-weighted and T2-weighted MR images were obtained of 73 patients with obstructive jaundice caused by various diseases. Fat-suppressed T1-weighted images were also obtained of 10 patients. Eleven patients with segmental intra-hepatic bile duct dilatation (cholestasis) showed segmental hyperintensity on T1-weighted images and/or fat-suppressed T1-weighted images and no signal intensity difference on T2-weighted images. Sixty-two patients with widespread intrahepatic bile duct dilatation showed no intensity difference on T1-weighted and T2-weighted images (P < .01). Segmental hyperintensity on T1-weighted images was correlated with intrahepatic cholestasis.     

Day-Night Variation of Urine Volume in Parkinson's Disease

Abstract: Studies on the circadian rhythm of urine excretion in healthy men have demonstrated that the maximal urine flow occurs in the early afternoon and the minimal around midnight. In this study, an abnormality in the variation of urine volume was found in parkinsonian patients. Urine samples were collected during daytime (9:00–21:00) and nighttime (21:00–9:00). Fifteen healthy control subjects were examined and found to excrete 60% during the daytime and 40% during the nighttime of the total urine volume. Sixteen parkinsonian patients excreted 43% during the daytime and 57% during the nighttime. In contrast to the control subjects, the parkinsonian patients excreted a smaller volume of their urine during the daytime than during the nighttime. This finding might be related to the degeneration of dopaminergic and/or nondopaminergic neurons in the brain which control urinary excretion.

二子合剂对糖尿病大鼠肾脏的保护作用

目的：探讨富含木脂素成分的中药牛蒡子、五味子组成的二子合剂对糖尿病大鼠肾脏的保护作用。方法：将SD大鼠建成链脲佐菌素诱导的糖尿病模型，设正常对照组、模型对照组、苯那普利治疗组、二子合剂大剂量治疗组及小剂量治疗组．4周后检测血糖、24h尿量、尿蛋白总量、尿白蛋白总量、血胆固醇、尿ET-1、TNF-α及肾组织病理变化。结果：与模型对照组相比，苯那普利组及二子合剂大剂量治疗组各项检测指标均有改善，两疗效近似。二子合剂小剂量治疗组仅见尿白蛋白总量及毛细血管襻面密度有减少。结论：牛蒡子、五味子合剂对糖尿病肾脏损害有一定的保护作用，其作用与剂量有相关性。     

单孔钻颅引流术治疗慢性硬膜下血肿80例临床分析

慢性硬膜下血肿（chronic subdural hematoma，CSDH）为受伤3W后出现硬膜下的血肿，是中老年患者轻微颅脑损伤后最为常见的颅内病变。约占颅内血肿的10％，起病隐匿，且临床表现无特征。虽然CSDH的治疗方法多种多样，但单孔钻颅闭式引流方法简单，操作容易，已成为神经外科医师普遍采用的方法。我们近3年来采用单孔钻颅闭式引流术治疗慢性硬膜下血肿80例，效果满意，现报告如下。     

重型颅脑损伤后应激性溃疡防治与胃肠道感染的相关性及对策

目的探讨重型颅脑损伤患者应用洛赛克对应激性溃疡进行防治与胃肠道感染几率增加之间的关系及治疗对策。方法回顾近3年来我院收治的重型颅脑损伤并存活30 d以上病人176例,测定不同时间胃液pH值并分析防治应激性溃疡与发生胃肠道感染的相关性以及相应对策。结果在126例持续应用洛赛克的患者中,持续应用＞7 d的患者胃肠道感染发生率明显高于持续应用≤7 d的病人。其余50例间隔应用洛赛克患者与126例持续应用洛赛克患者相比,应激性溃疡发生率无明显差别,但间隔应用洛赛克患者胃肠道感染发生率较持续应用洛赛克＞7 d的患者明显下降。结论重型颅脑损伤患者应激性溃疡防治＞7 d者,由于胃酸分泌严重抑制,增加胃肠道感染发生率。间隔性应用洛赛克治疗在抑制胃酸分泌,减少应激性溃疡发生的同时,可明显减少胃肠道感染的发生。
