RESULTSdiabetic rats showed typical symptoms involving elevated serum glucose and weight loss (2)The rats in DM+VaD group reacted slower and made more error numbers in Y-maze than the rats in VaD group did, with a prolonged total reacting time in a whole day.(3)More neurons with serious damages, such as edema, ischemia or pyknosis could be found in DM+VaD group than in VaD group. More disarrangement of cone neurons, obvious glia proliferation, and more neuron apoptosis were found in CA area of hippocampus. CONCLUSIONS (1)2-VO in STZ-induced diabetic rats succeeded in establishing VaD animal models.(2) The cognitive dysfunction induced by VaD rats had been deteriorated by diabetes mellitus.(3)Morphology evidences proved that diabetes mellitus aggravated brain damages induced by VaD.PART II Effect of diabetes mellitus on the cholinergic nervous systemin CA1 area of hippocampus of VaDOBJECTIVE To estimate the role of cholinergic nervous system in hippocampus during the process of cognitive dysfunction aggravated by diabetes mellitus in DM+VaD group. METHODS Observe the changes of ChAT protein by immunohistochemistry stain. Chose three rats randomly from each group at each pointat two week, four week, and eight week, then sepa

Each has a 25-1/2 scale, mahogany neck, and ebony fingerboard.

每个型号拥有25-12的有效弦长，桃花心木琴颈和乌木指板。

We sutureed the fascia and muscle in front of the vertebral tansverse process and got the result of aneurysm outpocketing. Another case was an injury of the internal jugular vein (0.3cm near the skull fundus) with shock, we pressed the distal internal jugular vein with a conglomeration of gelatin songe.

其一为椎动脉在第二颈椎左侧横突处的损伤并伴假性动脉瘤，缝合横突前方残余颈长肌及筋膜，达到与动脉瘤外包裹术相同的效果；另1例为颈内静脉出颅处的不全离断伴休克，远心端在不能结扎和缝合止血的情况下，用明胶海棉揉成团块填塞、压迫，止血疗效肯定。

Plenty of modern features for big sounds! The Jim Root Telecaster (designed for the Slipknot/Stone Sour guitarist) will go to 11! Special features include a mahogany body, EMG pickups, 22 Dunlop 6100 jumbo frets, black locking tuners and hardware, and a single volume knob.

JimRoot (Slipknot 和 Stone sour 的吉他手)的新款Fender Telecaster，桃花心木琴身，琴颈EMG60 和琴桥EMG81 拾音器22品，漆面琴身，黑色部件，琴头弦锁，三档拾音器切换以及单音量控制旋钮。

In view of product quality of cross wedge rolling semifinished product of automotive power-shift box middle shaft which has heavy sectional shrinkage,numerical simulation and experimental method were adopted to analyze single wedge rolling and second wedge rolling method.

针对用楔横轧工艺生产具有大断面收缩率特点的汽车变速箱中间轴毛坯所存在的产品质量问题，利用数值模拟与实轧试验对汽车变速箱中间轴毛坯一次楔成形和二次楔成形进行了分析研究，发现采用一次楔成形方法加工汽车变速箱中间轴毛坯，轧件不易发生弯曲，中间断面收缩率最大处没有发生缩颈现象，心部质量也较二次楔成形好。

In view of product quality of cross wedge rolling semifinished product of automotive power-shift box middle shaft which has heavy sectional shrinkage, numerical simulation and experimental method were adopted to analyze single wedge rolling and second wedge rolling method. It is found out that contrast second wedge rolling, single wedge rolling will not make workpiece bend easily, and after rolling the workpiece has no neck shrinkage.

In an attempt to determine non-invasively the sino-atrial conduction time, we recorded the sinus node electric activity by placing bipolar electrodes at the level of the right atrium anteroposteriorly across the chest of the dog.

本实验采用成年狗，以6极心导管电极从颈外静脉插至上腔静脉与右心房交界处，能记录到一个在心电图P波以前19—26毫秒的&P前波&。通过夹除窦房结和高血钾等实验证明，&P前波&可与P波分离而存在，并随窦房结夹除而消失。

The slip knot was tightening by the drawn-string through the cardiac catheter which can be removed after decannulation. The modified Dennis cannulation was done with left ventricular assistance from the left atrium (via right external jugular vein) to the right subclevian artery in 6 dogs.

这种方法用于从右颈外静脉到左心房插引流管，和从右锁骨下动脉插灌注管行左心辅助的试验犬6例，在拔管后房间隔插管处可被闭合。

The autonomic efferent pattern of the baroreflex resetting induced by DPN stimulation was observed through recording renal sympathetic nerve activity , splanchnic nerve activity , cardiac sympathetic nerve activity , ganglioglomerular nerve activity and lumbar sympathetic nerve activity , discharge of single sympathetic fiber separated from the deep peroneal nerve and discharge of single sympathetic fiber separated from the superficial peroneal nerve , and cervical vagal efferent single fiber discharge .

通过记录肾、内脏、心、颈和腰交感神经的放电以及记录腓深和腓浅神经中交感单纤维和颈迷走传出单纤维的放电，观察了刺激DPN重调定压力感受性反射的自主神经传出型式。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
