Inhibitory effect of glycyrrhiza uralensis fish and chelidonium majus L on gastrocarcinogenesis induced by N-methyl-N′-nitron-N-nitrosoguanidine

In order to investigate the antagonistic effect of Glycyrrhiza Uralensis Fish (GUF) and Chelidonium maJus L (CML) on gastrccarcinogenesis induced by MNNG in Wastar rats, we treated the rats with MNNG alone (group 1) and with MNNG plus GUF and CML (group 2 and 3) respectively. The incidence of infiltrating adenocarcinoma of the glandular stomach and duodenum in group 2 was significantly lower than that in group 1 (26.7% vs. 67.8%). The differentiation and aggressivenees of carcinomas occured in group 2 were much better and mild than those in group 1. Present study also demonstrated that the inhibitory effect of CML on proliferation of human stomach carcinoma cell line MGC-803 was very remarkable; in addition, GUF and CML were able to antagonise the mutagenic activation of MNNG. These results suggest that GUF and CML may be empoyed in prevention of gastric carcinoma.     

短暂性脑缺血发作患者血浆中TXB2和PGF1α含量检测

本文用放射免疫法测定47例短暂性脑缺血发作(TIA)患者血浆中血栓素B_2(TXB_2)和6酮-前列腺F_(1α)(PGF_(1α))的含量。结果发现TIA患者血浆中TXB_2含量增高,PGF_(1α)降低;头颅CT或MRI示有小灶性梗塞者及TIA发作持续时间长于30min者TXB_2升高和PGF_(1α)降低更显著。治疗3个月后,血浆PGF_(1α)显著增高。TXB_2和PGF_(1α)在体内的失平衡是急性脑血管疾病发病的重要机理之一。     

应用聚合酶链反应（PCR）检测乙型肝炎患者的HBV一DNA

应用聚合酶链反应（ｐｏｌｙｍｅｒａｓｅｃｈａｉｎＲｅａｃｔｉｏｎ，ＰＣＲ）检测１０８例乙型肝炎患者血清中ＨＢＶ一ＤＮＡ，在不同类型的ＨＢＶ感染标志物（ＨＢＶＭ）的血清中结果有所不同：（１）在ＨＢｓＡｇ、ＨＢｅＡｇ和抗ＨＢｃ阳性血清中，ＰＣＲ阳性率８６．１１％（３１／３６）；（２）在ＨＢｓＡｇ、抗ＨＢｅ和抗ＨＢｃ阳性血清中，ＰＣＲ阳性率５５．８８％（１９／３４）；（３）在抗ＨＢｓ、抗ＨＢｅ和ＨＢｃ阳性血清中，ＰＣＲ阳性率为２０％（２／１０）；（４）在抗ＨＢｅ和抗ＨＢｃ阳性血清中，ＰＣＲ阳性率为２５％（２／８）；文中就ＰＣＲ检测的结果及临床意义作了扼要的讨论。     

The subdivisions of the intermediolateral nucleus in the sacral spinal cord of the cat

The subdivisions of the sacral intermediolateral nucleus (IML) of the cat have been studied by using a double-labeling technique of retrograde Fluoro-gold (FG) and wheat germ agglutinin-conjugated horseradish peroxidase (WGA-HRP) tracing. The parasympathetic preganglionic neurons (PGNs) that were labeled by the FG injected into the pelvic nerve formed a ‘V’-shaped column known as the sacral parasympathetic nucleus (SPN) in the sacral IML. The neurons that were labeled by the WGA-HRP applied to the lateral parabrachial nucleus (PBL) formed an elongated spindle-shaped column extending throughout the IML of the sacral segments. We designated it by the name of sacral visceral sensory nucleus (SVSN). These findings indicate that the sacral IML of the cat contain two distinct subdivisions, SPN and SVSN.     

BGM细胞,Hela细胞,HEL细胞与A549细胞对HSV—1敏感性的比较

用单纯疱疹病毒－１型（ＨＳＶ－１）感染ＢＧＭ细胞、Ｈｅｌａ细胞、ＨＥＬ细胞及Ａ５４９细胞，利用空斑试验，比较四种细胞对ＨＳＶ－１的敏感性。结果示，ＨＳＶ－１在ＢＧＭ细胞培养中空斑形成单位（ＰＦＵ）数最多，出现细胞病变的时间早。提示ＢＧＭ细胞可为ＨＳＶ－１的分离培养提供一种新的、敏感细胞。     

急性心肌缺血时红细胞变形性的变化及其机理

本实验观察了犬急性心肌缺血时体循环血与缺血区局部静脉血中红细胞变形性（ＲＣＤ）的变化。结果表明，阻断冠脉血流后高切变率下全血粘度（ηｂｈ）和红细胞刚性指数（ＥＲＩ）明显增高，而缺血区局部血液中此二者的变化明显大于体循环静脉血。事先切断内脏大神经，可使阻断冠脉后体循环血（而不是局部静脉血）的ηｂｈ和ＥＲＩ变化基本消失。缺血区局部血液ｐｈ和ｐＯ２明显降低，ｐＣＯ２明显增高，红细胞内ＡＴＰ含量减少和钙含     

Graves病患者血甲状旁腺激素、钙、磷、碱性磷酸酶基础值的观察

对照观察了28例Graves病患者及29名正常人血浆甲状旁腺激素、(PTH)血钙、血磷、碱性磷酸酶的基础值。Graves病组血碱性磷酸酶明显高于对照组,而PTH、钙、磷无显著差异。Graves病组血钙>2.75mmol/L者占21%,与某些文献大致相符。正常组血钙与PTH基础值间呈负相关,而Graves病组该两值间无相关,提示Graves病时血钙浓度的平衡调节中PTH以外的因素如甲状腺激素等可能对其影响较大。     

胃粘膜上皮“适应性细胞保护”机制防止胃肿瘤发生的作用

投用致癌剂的对照组其胃肿瘤发生率为22.2％。若同时给予40％Z醇液空腹灌胃,则胃肿瘤发生率达55.9％。如在给乙醇液前15分钟,先给予4％的辣椒煎液灌胃,则胃肿瘤发生率只有20.0％,相近于对照组的水平(后2组差别有极显著意义,P<0.01)。这种给损伤剂(乙醇)之前先给予微刺激剂(辣椒)所产生的胃粘膜的保护作用,是通过促使胃粘膜上皮细胞合成内源性前列腺素(PGs)来实现的,是一种“适应性细胞保护”机制。这种保护胃粘膜的作用可降低胃肿瘤的发生率。
