Two series of experiments were carried out on 109 young female albinorats.In the first series the spinal cord was hemisected at the mid-thoraciclevel and examined from 1 hour to 240 days after operation for degenerationand regeneration.In the second series the spinal cord was transected at themid-thoracic level.In order to influence the condition of scar tissue,segmentsof degenerated sciatic nerve were used as grafts for auto- and homo-trans-plantations.In the latter case some of the grafts were stored in ice-box (2℃)for 2 days before grafting.After 7 to 120 days the effects of different trans-plantations on regeneration were studied.Sections of the specimens were pre-pared by a modified Glees' silver impregnation method,and some were coun-terstained with Mallory's triple stain.One hour after injury,some of the cut ends of the nerve fibers swelledand showed increased argyrophilia.Six hours later typical Cajal's retractionballs were found at the cut ends of some fibers.Later on they detached them-selves from the axons and broke into fragments and disappeared gradually.Twenty-four hours after injury some ascending fibers showed Walleriandegeneration.On the third day a great number of them had degenerated andthe maximum degeneration was observed on the fifth day.The fragments ofWallerian degeneration persisted for a long time.Twenty-four hours after the operation a few regenerating fibers withgrowth cones at their tips were observed.It was found that as the regenera-tion proceeded some of the regenerating fibers degenerated and disappeared.Transplantation of segments of degenerated nerves resulted in alteration of the structure of scar tissue and enabled regenerating fibers grow along thelong axis of the cord.Most regenerating fibers that grew into the transplantscame from the dorsal root,only a small portion came from the cord proper.The number of regenerating fibers in the transplants varied with their posi-tion,the occurrence of necrosis within them and density of the surroundingscar.It was found that auto-transplantation had the best effect,homo-trans-plantation after cold storage came next and homo-transplantation without coldstorage produced the least effect.It was found that the regenerative capacity of the spinal cord was com-paratively slight and that the nerve fibers did not regenerate uniformly.Mostregenerating fibers in the scar tissue came from dorsal funiculus,some origi-nated from the ventral horn cells,only few of them came from the graymatter and the fasciculus proprius.Other fibers regenerated only occasionally.Transection of spinal cord resulted in paralysis of the hindlimbs but reflexactivity remained intact.In animals whose spinal cord had been hemisected,the coordination of locomotion was recovered in a few days.It is evident,that the central nervous system of albino rat possesses remarkable compensatorypower.The factors causing the failure of regeneration in the central nervoussystem are discussed.

1.本报告系采用体重70—100克较幼的雌性大白鼠,在第6—8胸椎平面半切断脊髓,手术后1小时至240天分期取出脊髓,用改良的Marsland,Glees及Erikson的石蜡镀银法染色,也有部分用Mallory三色法复染,系统观察脊髓内轴突的溃变和再生。另外用已溃变的坐骨神经进行自体、同种和冷藏后再行同种移植的方法来填补脊髓的缺损,观察不同的移植方法和移植块对脊髓再生的影响。2.脊髓内少数纤维的断端,在损伤后1小时初显改变,6小时已形成Cajal式典型的缩回球,24小时已有少数缩回球和轴突分离,经破裂成碎片而逐渐消失。从15天以后,各期都看到少数再生纤维的尖端形成嗜银性很强的类似缩回球的肿大,此现象在240天仍继续发出。3.切断纤维的两端都能形成缩回球,其形状、部位和纤维的直径有密切的关系。棒状缩回球主要由粗纤维形成,离切口较远;球状缩回球大部分紧靠切口的边缘,由细纤维的断端所形成。4.损伤后24小时,少数上行纤维开始华氏溃变,第3天有显著的增加,第5天已达最高峰。华氏溃变产生的碎片的消失极为缓慢,在240天仍有部分碎片散布在结节状肿大的纤维之间。5.带有生长锥的分枝再生纤维,在手术后24小时开始形成,但数量极少。有一些分枝的再生纤维继续生存150天或更长。在再生过程中经常有少数再生纤维发生溃变而消失。6.移植已溃变的神经能够部分改变脊髓内瘢痕的结构,使再生纤维沿着脊髓纵轴生长,有利于纤维的再生;但是移植块常引起较严重的炎性反应,被致密的结缔组织所包绕,阻碍再生纤维长入移植块。7.长入移植块的再生纤维,极大部分来自后根,少数东自后索,也有一些可能来自灰质。移植块内再生纤维的数量是随着移植块所在的部位、放置的方向、周围瘢痕的致密程度及是否发生局部坏死而转移。8.自体移植的效果最好,淋巴细胞的浸润比较轻,再生纤维最丰富。冷藏后同种移植的次之。同种移植由于在移植块中心常发生局部坏死而引起较严重的炎性反应,影响了再生纤维的长入。9.脊髓内神经纤维的再生能力较微弱而且是不一致的,瘢痕内的再生纤维以后索的上行纤维来的较多,前角细胞次之,极少的来自灰质和固有束,其他纤维的再生更为少见。脊神经的后根常有大量的再生纤维长入瘢痕。10.脊髓侧索在损伤后15天初显收缩,随后更为显著。其收缩的程度在近侧段和远侧段相似,在90天受伤侧的侧索的厚度只有正常侧的一半左右。11.所有全切断脊髓和移植动物,除呈现反射活动外,都没有发现后肢的协调运动;但是全部脊髓半切断动物在手术后3—7天都已经恢复正常的协调步态。可见大白鼠的中枢神经系是具有高度的代偿机能。12.中枢神经系再生失败的原因曾加以讨论。

A total of 23 adult rabbits were used in this study. Six were used as control andthe remaining 17 rabbits were injected with adrenaline to produce cardiac lesion. Theseanimals were sacrificed alternatively either by medullary-shock or clacium block after 1,3, 5, 7, 10, 14 and 21 days of experiment. The left ventricle was excised and fixed inCarnoy fixative, embedded in paraffin, stained with either H-E or PAS (McManus)method.

A total of 23 adult rabbits were used in this study. Six were used as control andthe remaining 17 rabbits were injected with adrenaline to produce cardiac lesion. Theseanimals were sacrificed alternatively either by medullary-shock or clacium block after 1,3, 5, 7, 10, 14 and 21 days of experiment. The left ventricle was excised and fixed inCarnoy fixative, embedded in paraffin, stained with either H-E or PAS (McManus)method. Slides of saliva digestion and PAS staining were used for the identificationof glycogen. The following points of conclusion were drawn: 1. More glycogen was present in the left ventricle of animals killed by calciumblock than those killed by medulla-shock. 2. The glycogen content in the outer and inner myocardial layers of the normalanimal killed by calcium block was identical and that of the middle layer was lesser.Since these myocardial layers perform different functions in ventricular contraction, theauthors suggest that the glycogen content of the different normal myocardial layers wasassociated with its function. 3. Medulla-shock causes anoxia of the heart. There were severe exhaustion ofglycogen in the outer layer during anoxia. The influence of anoxia was restricted to theintersinusal region (the parasinusal region was less influenced) of the middle layer. Theinfluence of anoxia to the inner layer was minimal. These phenomena were interpretedas due to the different blood sources of each layer. 4. In the myocardium of the shocked animals, glycogen was constantly stagnatedat the following places: the perisinusal fibers of the middle layer, the lateral boundariesof the papillary muscle, and the inner layer of the myocardium. These phenomena fur-ther proved the relationship between the glycogen distribution and the blood supply. 5. The perilesion deposition of glycogen due to adrenaline was not influenced bythe process of anoxia in any layer of the myocardium. The abnormal glycogen disap-peared coincidentally with other cytoplasmic material during degeneration. So, it wasbelieved that this glycogen probably was combined with the protein. The range ofabnormal glycogen distribution was in accordance with the severity of the lesion. 6. Within the first 5 days of our experiment, the focal lesion had not yet form-ed, the injury of individual fiber was variable and so did glycogen distribution. Afterthe 14th experimental day, the lesion was replaced by scar tissue and the perilesion car-diac fibers reappeared to normal. Thus, there was no abnormal glycogen deposit in thatregion. Only between the 5th and 14th experimental days, the abnormal glycogen de-position was distinct.

作者应用肾上腺素产生实验性心肌病变。从钙杀死及捶死的正常及实验的家兔心肌PAS及H.E染片的观察中,作者得出下列几点结论: 1,钙杀死的动物较之捶死动物的心肌含有更多的糖原。 2,钙杀死动物心肌内层与外层糖原含量相等而其功能皆为缩短心室纵径;司心室横径收缩的心肌中层糖原较少。因此作者认为心肌各层糖原含量与其功能有关。 3,乏氧对心肌糖原的影响以外层最显著,心肌中层的血窦间地区(不包括血窦旁地区)糖原消耗较多,而乏氧对心肌内层亦有一定影响。作者认为以上差别是与其血液来源相关。 4,在捶死动物中,血窦旁及乳头肌两侧以及心肌内层皆保留糖原一事再次证明糖原与血液供应的关系。 5,心肌异常糖原不受乏氧影响,它可能是与蛋白貭结合的糖原。 6,5—14天的病灶周旁异常糖原较多。14天以上的病灶结瘢修复,其周旁纤维康复,无异常糖原。在5天以内的材料中,病灶尚未形成,病变纤维周旁的纤维因受损与恢复程度不同故而糖原分布极不恒定。

This paper is to describe a new ostracode genus,Paramoelleritia,which includes5 new species(P.xiangzhouensis,P.miaohuangensis,P.subovata,P.subtrapezoidalis,P.beiliuensis)and 2 new subspecies(P.xiangzhouensis magna,P.miaohuangensisparva),all collected from the“Sipai Formation”and the“Yingtang Formation”inthe Xiangzhou and Wuxuan districts,and the Beiliu Formation in the Beiliu districtof Guangxi.The new genus Paramoelleritia under study is easily distinguished from theother genera of the Family Leperditiidae by a clear curving-conic mandibular mus-cular scar(known commonly as“chevron”),which has also recently been found inthe Middle Devonian forms from Southern China.It seems probable that such aconic-shaped mandibular muscular scar originated from a V-shaped one in those ofLower Devonian,representing an advanced type.Therefore,it may be suggested thatin the Family of Leperditiidae,the arrangement of mandibular muscular scar haschanged evolutionarily from irregular to V-shaped and then to conic-shaped.Besides,the new genus Paramoelleritia is closely allied to Moelleritia from theMiddle Devonian formations of Canada and U.S.S.R.and the Paramoelleritia-bearingbeds may be referable to the Middle Devonian.
