Medullary locomotor strip and column in the cat

Responses of lateral medullary neurons to microstimulation of two points in the locomotor strip—rostral and caudal to the obex—were recorded intracellularly in mesencephalic decerebellated uncurarized cats. Excitatory and inhibitory postsynaptic potentials and orthodromic action potentials occurred up to 20 ms after a single stimulus. A number of cells responded to stimulation of a locomotor point by a repetitive discharge, and in some cells synaptic responses were evoked by contralateral stimulation. The responsive neurons were scattered among other cells in the lateral medullary tegmentum. At least one-third of neurons with synaptic responses to stimulation of the rostral locomotor point were antidromically invaded from the caudal one. The characteristic length of these descending axons was between 4 and 9 mm, although there were longer axons too.The lateral medullary cells which give synaptic responses to stimulation of the locomotor strip form the locomotor column located medial to the strip, and a portion of these cells send their axons to the strip. It is suggested that the activity is propagated polysynaptically along the column through axonal collaterals of its neurons. One can assume that when repetitive stimulation achieves a threshold for locomotion such a propagation occurs without decrement. As a result, spinal stepping generators are activated.

Pseudophakic accommodation with translation lenses – dual optic vs mono optic

PURPOSE: To investigate the pseudophakic accommodation effect in dual and mono optic translation accommodative intraocular lenses (AIOL) using linear matrix methods in the paraxial space. METHODS: Dual (anterior optic of power +32 D linked to a compensatory posterior optic of negative power) and mono lens power was determined in the non-accommodated state using linear geometric optics based on the Gullstrand model eye. The position of the AIOL was calculated from a regression formula. Pseudophakic accommodation was assessed with three systems: (1) forward shift of the mono optic lens, (2) anterior translation of the anterior optic in the dual optic lens system with an unchanged position of the posterior minus lens and (3) symmetrical anterior and posterior translation of the anterior and posterior lens. The Gullstrand model eye was modified by changing the axial length (and proportionally changing the phakic anterior chamber depth) to investigate the accommodative effect in myopic and hyperopic eyes. RESULTS: The dual optic lens system (2) yields a nearly constant accommodation amplitude of 2.4-2.5 D mm(-1) movement over the total range of axial lengths. The mono optic lens (1) provides a higher accommodative effect only in extremely short eyes (high refractive power of the lens), whereas for normal eyes (1.4-1.5 D mm(-1) movement) and for long (myopic) eyes the accommodative effect is much less than the dual optic lens. The dual optic lens system under condition (3) yields less accommodation amplitude compared with the dual optic system under condition (2) over the total range of axial length but provides higher accommodation amplitude compared with the mono optic lens system (1) with axial lengths greater than 22.3 mm (lens power 25.5 D). In the accommodated state, with lens translation of 1 mm, the absolute value of the lateral magnification increases with the refractive power of the mono optic lens (1) and decreases in both dual optic lens systems (under conditions 2 and 3). CONCLUSIONS: A mathematical strategy is presented for calculation of the accommodative effect of mono-optic and dual optic AIOL. The dual optic lens yielded a nearly constant accommodation amplitude of about 2.4-2.5 D mm(-1) translation, whereas the mono optic lens yielded an accommodative response of <2 D mm(-1) translation in long myopic or normal eyes. Only in extremely short eyes is the accommodative amplitude of the mono-optic lens higher than the dual optic lens.     

乙醇氧化酶两点速率法测定血清微量乙醇

目的：建立一个灵敏、准确、特异、试剂稳定的乙醇氧化酶法用于测定血清微量乙醇浓度。方法：利用乙醇氧化酶与过氧化物酶偶联，通过优化反应体系及自动生化分析仪分析参数，采用两点速率法对乙醇进行分析。结果：乙醇浓度在2000mg／L以下线性良好；批内RSD小于2．81％，批间RSD小于4．51％；平均回收率为100．7％；本法（Y）与气相色谱法（X）比较具有良好的相关性，Y=0．996X＋3．58，r=0．981。胆红素159．1μmol／L、甘油三酯14．31mmol／L、血红蛋白5．8g／L以下对本法测定乙醇结果无干扰。结论：建立的两点速率法测定乙醇灵敏度高、准确度、特异性均较好，特别适合于血清乙醇浓度处于轻度超标的疑似酒后者的标本检测。     

月经前后手三阴经原穴伏安特性

目的:观察健康女性月经前后穴位伏安特性的变化规律,研究穴位伏安特性与人体气血变化的关系,创建气血变化定量研究新方法。方法:应用自制的穴位伏安特性计算机检测系统对健康女性月经前、月经时及月经后手三阴经原穴太渊、大陵、神门进行伏安特性检测。结果:月经前后太渊、大陵、神门穴均有部分扫描点电阻发生了明显的变化,以大陵最为明显、太渊次之、神门最不明显,差异均有统计学意义。在三个穴位所有电阻发生明显变化的扫描点中,穴位电阻随月经进程变大的比率为70.6%。结论:穴位伏安特性随月经的进程而变化,这种变化具有穴位特异性。穴位电阻随月经进程而变大,这可能与月经后机体血量减少有关。穴位伏安特性有可能作为研究气血变化的定量指标。
