妊娠合并病毒性肝炎15例肝穿刺病理检查 总被引:3,自引:0,他引:3
材料和方法自1986年8月至1986年12月我们对本组15例妊娠并发较重或重症肝炎住院孕产妇进行了肝穿刺,其中妊娠早期1例,中期5例,晚期7例,产后1个月及30个月各1例。术前准备及穿刺部位的定位:本组穿刺均按常规进行,穿刺时借助B 超进行穿刺部位的定位,采用Menghini 氏1秒钟针刺吸引法。①血尿常规、出凝血时间、血小板计数和凝血酶原时间测定均应在正常范围以内。血小板计数不应低于50×10~(?)/L。②术前三日肌注维生素K_110mg qd。③术前2~3日静脉滴注凝血酶原复合物(PPSB)1瓶(400U)qd。手术当日再给予PPSB400U 静脉滴 相似文献

The rhesus monkeys receiving 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) produces typical parkinsonian syndrome close to the nature of human Parkinson's disease (PD), including the triad of akinesia, rigidity and tremor, the reduction of dopamine (DA) contents in the nigrostriatum, and severe degeneration of nerve cell in the substantia nigra (SN). Thus, the MPTP-treated monkey provides a useful animal model that can be used to study the etiology and pathogenetic mechanisms of PD and to explore new approaches for the treatment of PD. 相似文献

宫内节育器引起出血机制的探讨 总被引:1,自引:0,他引:1
本文用萤光桃红——肼黄染色法观察了放置与未放置IUD的妇女子宫内膜颗粒细胞变化。发现IUD组内膜颗粒细胞提早出现在增殖期子宫内膜;分泌期内膜中出现内膜颗粒细胞集聚现象的比例明显高于对照组(p<0.05)。并发现内膜颗粒细胞集聚处有网状纤维溶解现象。文内对IUD引起子宫出血的机制进行了探讨,认为可能与内膜颗粒细胞释放松弛素有关。 相似文献

STUDY ON MPTP-INDUCED PARKINSONIAN ANIMAL

L-methyl . 4 - phenyl-1,2,3,6 - tetrahydropyridinc
(MPTP) was used to produce thesus monkey parkin
scnian animal models. We also studied the mechan
ism of action of MPTP by testing with monoaminc
oxidase B (MAO-B) inhibitor, L-deprenyl, and a
neuropeptide, L-prolyI-L-leucyl-glycinamide (PLG),
::gainst MPTP ncurotcxicity. The experimental
results indicate that MPTP can produce a useful
thesus monkey parkinsonian animal model. Pretreat
ment with L-deprenyl can effectively prevent MPTP
neurotoxicity, and the mechanism of action of L
deprenyl against MPTP seem to be blocking of MPTP
conversion t0 1 methyl-4-phenyl-pyridinium (MPP)
by inhibiting MAO~B activity. Whether PLG can
prevent or alleviate MPTP neurotoxicity remains to
be studied. 相似文献
