鸡鼻腔组织学特点及鼻相关淋巴组织分布的研究
鸡 鼻腔 鼻相关淋巴组织
2014/4/9
旨在通过组织学方法对鸡鼻腔结构组织特点以及鼻相关淋巴组织的分布进行系统研究。选用25只3日龄白来航鸡，分别于10、21、35和60日龄宰杀，分离整个鼻腔。经波恩液固定48 h后，一部分鼻腔组织沿矢状面和横断面切成连续断面，实体显微镜下观察解剖学结构；一部分用于组织学结构观察：固定后，10日龄雏鸡的鼻腔直接进行石蜡包埋，21日及以上日龄的鸡鼻腔先用甲酸脱钙再石蜡包埋。所有鼻腔沿纵轴选取5个横断面进行...
T he relative order of mK channels, free radicals and p38 MAPK in ATP preconditioning’s protective pathway in rat heart
Free radicals Infarction Ischemia Mitochondria Preconditioning Signal transduction
2004/3/31
Ischemic preconditioning (PC) reduces myocardial infarction by a mechanism that involves opening of mitochondrial
ATP-dependent potassium channels (mK ), reactive oxygen species (ROS), and possibly a...
Skin electroporation for transdermal and topica l delivery
Electroporation Skin permeability Transdermal delivery Topical delivery Mechanism Safety
2004/3/31
Electroporation is the transitory structural perturbation of lipid bilayer membranes due to the application of high voltage
pulses. Its application to the skin has been shown to increase transdermal ...
Increased vasoconstricti on to noradrenaline by 1400W, inhibitor of iNOS, in rats with streptozotocin-in duced diabetes
Capacitance Mean circulatory filling pressure Noradrenaline Vasoconstrictio
2004/3/31
There is evidence that inducible nitric oxide synthase (iNOS) is activated at the acute phase of diabetes. We examined if selective
inh ibitio n of iNOS by 1400W ( N -3-amino methyl -benz yl- acetami...
Activation of Mitochondrial ATP-Dependent Potassium Channels by Nitric Oxide
ischemic preconditioning nitric oxide myocytes mitochondria
2004/3/31
We measured mitochondrial redox potential as an index of mitoKATP
channel opening in rabbit
ventricular myocytes. The NO donor S-nitroso-N-acetyl- DL-penicillamine (SNAP, 0.1 to 1 mmol/L) oxidized t...
Acute negative inotropic effects of homocysteine are mediated via the endothelium
homocysteine mediated via the endothelium
2004/3/31
This study was designed to determine whether homocysteine
also has acute effects on cardiac systolic function, because
such actions may complement the previously described chronic
effects on cardia...
The augmentation of brain thioredoxin-1 expression after severe hypobaric hypoxia by the preconditioning in rats
Hypobaric hypoxia Preconditioning Antioxidants Thioredoxin-1 Immunocytochemistry
2004/3/31
Induction of endogenous antioxidants is one of the key molecular mechanisms of cell resistance to hypoxia/ischemia. The effect of severe
hypoxia on the expression of cytosolic antioxidant thioredoxin...
On-line programming of simple movement sequences
Electromyography Motor control Reaction time
2004/3/31
The conditions under which subjects can program sequences of forearm extension-flexion
movements on-line and those in which subjects are forced to preprogram was investigated.

Electric fields can induce pore formation and other struc-tural defects in lipid membranes, including cell mem-branes and skin [1,2]. Electroporation is widely used in
the laboratory for gene transfe...
