Paraneoplastic intestinal pseudo-obstruction associated with high titres of Hu autoantibodies

Anti-Hu autoantibodies in high titres, as revealed with immunocytochemistry and Western blot, were present in a patient with gastrointestinal pseudoobstruction and small-cell lung cancer (SCLC) bearing the Hu antigen. Marked neuron and nerve fibre loss were found in the myenteric plexus at postmortem. These findings show that neuronopathic Hu-associated gastrointestinal pseudo-obstruction can occur as the only paraneoplastic neurological symptom in patients with SCLC.

Pretreatment with human serum butyrylcholinesterase alone prevents cardiac abnormalities, seizures, and death in Göttingen minipigs exposed to sarin vapor

Human serum butyrylcholinesterase (Hu BChE) is a stoichiometric bioscavenger that is being developed as a prophylactic countermeasure against organophosphorus nerve agents. This study was designed to evaluate the efficacy of Hu BChE against whole-body inhalation exposure to a lethal dose of sarin (GB) vapor. Male Göttingen minipigs were subjected to: air exposure, GB vapor exposure, or pretreatment with Hu BChE followed by GB vapor exposure. Hu BChE was administered by i.m. injection 24 h prior to exposure to 4.1 mg/m³ of GB vapor for 60 min. Electrocardiograms (ECG), electroencephalograms (EEG), and pupil size were recorded throughout exposure. Blood drawn before and throughout exposure was analyzed for blood gases, electrolytes, metabolites, acetylcholinesterase and BChE activities, and amount of GB present. Untreated animals exposed to GB vapor exhibited cardiac abnormalities and generalized seizures, ultimately succumbing to respiratory failure. Pretreatment with 3.0 or 6.5 mg/kg of Hu BChE delayed blood gas and acid–base disturbances and the onset of cardiac and neural toxic signs, but failed to increase survivability. Pretreatment with 7.5 mg/kg of Hu BChE, however, completely prevented toxic signs, with blood chemistry and ECG and EEG parameters indistinguishable from control during and after GB exposure. GB bound in plasma was 200-fold higher than plasma from pigs that did not receive Hu BChE, suggesting that Hu BChE scavenged GB in blood and prevented it from reaching other tissues. Thus, prophylaxis with Hu BChE alone not only increased survivability, but also prevented cardiac abnormalities and neural toxicity in minipigs exposed to a lethal dose of GB vapor.     

温、湿度变化对木质人造板材甲醛释放影响

目的研究温、湿度对木质人造板材甲醛释放影响，建立不同温、湿度甲醛释放预测模型。方法利用环境气候舱获得不同温、湿度板材甲醛释放量。结果温度和甲醛释放量呈线性关系（P〈0．05，校正R^2=0．9963）；湿度和甲醛释放量呈抛物线关系，拟合线性回归方程为：Yhat=0．6368＋0．0821Te-0．0695Hu＋0．0007Hu^2，在温度固定的情况下，湿度为46．9％时，甲醛释放量达最小值。结论甲醛释放量随温度增高而增大。随湿度增加先小幅下降后上升，提示夏天预防高浓度室内装修污染的危害尤为重要。

Appraisal of anti-inflammatory and free radical scavenging activities of ethanol extract of Ilex ficoidea Hemsl and Ilex centrochinensis S.Y. Hu

This study was to appraise the anti-inflammatory and free radical scavenging activities of ethanol extracts of Ilex ficoidea Hemsl (EIFH) and Ilex centrochinensis S.Y. Hu (EICC). Anti-inflammatory activities were evaluated using xylene-induced ear edema and the cotton pellet granuloma tests. Some antioxidants produced during chronic inflammation were quantitated and the DPPH, superoxide anion and hydroxyl free radicals scavenging activities in vitro were also investigated. EICC showed a significant anti-inflammatory effect during the acute inflammation and chronic inflammation without any acute oral toxicity. However, EIFH exhibited a negligible anti-acute inflammatory and a moderate anti-chronic inflammatory activity. EICC significantly inhibited the formation of MDA and markedly raised the activities of SOD, CAT and GSH-Px. EIFH could reduce the level of MDA and elevate the activity of SOD only at the high dose. The free radical scavenging activities of EICC are higher than that of EIFH. These results suggest that EICC possesses significant anti-inflammatory and free radical scavenging activities. The anti-inflammatory mechanism is attributed, in part, to enhance the activities of antioxidant enzymes.
