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...

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。

The regeneration of corneal nerves were observed after experimental penetrating keratoplasty in 40 rabbits by the cholinesterase histochemistry. It has been demonstrated that the first signs of regenerating axons were seen 1 week postoperatively in the severed end of nerves. After 4 weeks several single regenerating axons extended into the graft through he scar between host and graft, while a teural proliferating reaction were apparnantly observed in the host cornea. The new neurites and the regenarating fibers all grew in the direction of the graft so that the neural density significantly incre ased in the host and near the scar. 6-10 weeks after the operation the number of regenerating fibers were increased in the peripheral graft, but only a few fine regenerating axons were seen in central part in spite of 3 months after the operation.

本文应用胆碱酯酶组织化学技术观察了实验性穿透角膜移植术后角膜AchE阳性神经的再生,证实术后一周,神经断端已有再生轴突形成;术后4周,可见单根纤维穿八植片,同时植床内神经呈明显增生反应;新生与再生纤维均向植片方向生长,使植床内及植床与植片交界区神经密度明显增大;术后6~10周,植片周边再生纤维数量逐渐增多,但植片中央至术后3月仍仅有少数细纤维形成。本文讨论了穿透性角膜移植术后角膜神经再生与角膜知觉恢复的关系。

In the present investigation, seven biotinlabelled lectins and avidin biotin-peroxidase complex were used to study the localisation and distribution of lectin receptors in skeletal muscle tissues of 16 patients with DMD and 11 normal controls. In DMD muscle, we found local absences in distribution of RCA-I. WGA. ConA and PNA receptors in theplasmalemma-basement membranes. The intracellular staining of small muscle fibers, was,observed with RCA-I. WGA and ConA. WGA and PNA staining apn parently increased in the proliferative endomysial and perimysial connective tissues. The results suggested that (1) the local absences of lectin receptors in muscle membrane might play an important role in pathogenesis of DMD; (2) the small muscle fibers with the intracellular positive staining might be regenerating fibers; (3) the increased lectin receptors in proliferative connective tissues might affect the myogenesis of the dystrophie human muscle.
