MPTP对鼠肝脂质过氧化作用的影响

本文报道给C57小鼠腹腔注射不同剂量1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP)后,发现组3(MPTP35 mg/kg,每天一次,共7天)鼠肝匀浆、线粒体和微粒体的膜丙二醛含量明显增加,与对照组相比分别增加70.5%,67%和51.4%(P<0.01),而组1(MPTP 35mg/kg,每4小时一次,共3次)和组2(MPTP35mg/kg,每天一次,共4天)鼠肝丙二醛含量与对照组相近。结果表明MPTP有明显地促进鼠肝脂质过氧化的作用,并与其剂量有关。     

Histopathological observations on orbital fatty tissue in dysthyroid ophthalmopathy

Seventeen specimens of orbital fatty tissue taken from cases of dysthyroid ophthalmopathy at the time of operation were observed by light and electron microscopy, and also by immunohistochemical staining. The pathological changes observed were infiltration of the chronic inflammatory cells, deposit of fibrin, sclerosis of vascular wall, occlusion of the vascular lumen, and accumulation of hydrophilic mucopolysaccharide. Immunoglobulin G was detected in fat cells and lymphocytes, and some of the infiltrating lymphocytes were determined to be T cells, by immunohistochemistry. These findings suggested that the pathology of the dysthyroid ophthalmopathy was closely related to the chronic inflammation induced by the immune reaction. The exophthalmos was considered to occur due to edema secondary to chronic inflammation and accumulation of the mucopolysaccharides.     

光照疗法对新生儿红细胞谷胱甘肽还原酶活性的影响

作者对光照疗法（光疗）前及光疗后于口服维生素Ｂ＿２（４３例）和不予口服维生素Ｂ＿２（１７例）的黄疸新生儿的红细胞谷胱甘肽还原酶（ＧＲ）的活性进行了动态观察。结果显示，接受短期光疗的黄疸新生儿其红细胞ＧＲ活性较光疗前的ＧＲ活性有显著下降，光疗后予口服维生素Ｂ＿２可使下降的红细胞ＧＲ活性回升，而不予补充维生素Ｂ＿２者的红细胞ＧＲ活性继续下降。光疗的时间越长，红细胞ＧＲ活性的下降越明显，补充维生素Ｂ＿２使红细胞ＧＲ活性回复到正常水平所需的时间也越长。短期光疗也可引起体内维生素Ｂ＿２的降解，导致红细胞ＧＲ活性的下降，为避免因红细胞ＧＲ活性下降引起的红细胞额外破坏，对接受光疗的黄疸新生儿常规补充维生素Ｂ＿２的是必要的。     

The effect of the selective PAF antagonist CIS-19 on PAF- and antigen-induced bronchoconstriction, microvascular leakage and bronchial hyperreactivity in guinea-pigs

We investigated the effects of a novel platelet-activating factor (PAF) receptor antagonist, CIS-19 [cis-2-(3, 4-dimethoxyphenyl)-6-isopropoxy-7-methoxy-1-(N-methylformamido)-1, 2, 3, 4-tetrahydronaphthalene], on PAF-, histamine-, substance P- and antigen-induced bronchoconstriction and microvascular leakage, as well as PAF- and antigen-induced bronchial hyperreactivity to methacholine in urethane-anesthetized guinea-pigs. Administration of CIS-19 (0.5–5 mg/kg, i.v.) inhibited the increase in lung resistance induced by PAF (30 ng/kg, i.v.) in a dose-dependent manner, but failed to inhibit the increase induced by histamine (30 μg/kg, i.v.) or substance P (6.5 μg/kg, i.v.). CIS-19 (5 mg/kg, i.v.) did not inhibit the increase in lung resistance induced by ovalbumin (2 mg/kg, i.v.) in actively sensitized guinea-pigs. PAF (30 ng/kg, i.v.)-induced microvascular leakage, measured by the extravasation of Evans blue dye, was dose-dependently inhibited by CIS-19 (0.5–5 mg/kg, i.v.) in the trachea, main bronchi and intrapulmonary airways, but it did not affect histamine (30 μg/kg, i.v.)- or substance P (6.5 μg/kg, i.v.)-induced microvascular leakage at all airway levels. CIS-19 (2.5 and 5 mg/kg) did not affect ovalbumin (2 mg/kg, i.v.)-induced microvascular leakage in all airway levels in actively sensitized guinea-pigs. CIS-19 (2.5 and 5 mg/kg, i.v.) significantly inhibited PAF-induced enhancement of the bronchial response to methacholine, but had no effect on ovalbumin (0.05 mg/kg, i.v.)-induced bronchial hyperreactivity in actively sensitized guinea-pigs. It is concluded that CIS-19 is a potent PAF receptor antagonist which inhibits PAF- but not antigen-induced bronchoconstriction, microvascular leakage and bronchial hyperreactivity. These results suggest that PAF plays little or no role in early airway responses following antigen challenge. Received: 29 April 1996 / Accepted: 10 October 1996

目的：研究青山抗癌注射液对动物移植性肿瘤生长的影响．方法：以小鼠移植性肉瘤S180和肝癌H22为模型，以顺铂(DDP)为阳性对照，生理盐水(阳)为阴性对照，观察青山抗癌注射液对肿瘤生长的影响。结果：青山抗癌注射液不同剂量组对小鼠移植性肉瘤S180和肝癌H22的生长均显示了明显的抑制作用，与NS对照组相比，P＜0.01，且呈现出量效关系．结论：青山抗癌注射液具有抑制肿瘤生长的作用.     

阿霉素不同剂量静脉注射的药动学及其临床意义

采用ＨＰＬＣ法测定１４例肿瘤患者使用不同剂量阿霉素的血药浓度，并计算药代参数。４０ｍｇ／ｍ２和２５ｍｇ／ｍ２两组的血药峰浓度、ＡＵＣ、Ｖｃ差异有显著性。阿霉素的药代动力学存在明显的个体差异，血药峰浓度、Ｖｃ、Ｋ１２与疗效相关。
