Anatomical studeis of the epidermal structures of the various organs at different developmental stages of different citrus species indicate that the density and maturity of the natural pores are intimately related with the amount of infection by the canker organism, Xanthomonas citri. Leaf and stem infections have been found to be heaviest during the stage of shoot elongation when large number of new stomates and lenticels are in the process of formation. No infection occurs at the top of new shoots where the...

Anatomical studeis of the epidermal structures of the various organs at different developmental stages of different citrus species indicate that the density and maturity of the natural pores are intimately related with the amount of infection by the canker organism, Xanthomonas citri. Leaf and stem infections have been found to be heaviest during the stage of shoot elongation when large number of new stomates and lenticels are in the process of formation. No infection occurs at the top of new shoots where the natural pores have not yet been formed. Old shoots with mature pores also cease to be susceptible to infection. Fruits are exposed to infection longer than the shoots. They are most susceptible from the end of May to the middle of June when stomatal development is most active. Few infections take place after 60 days of the fruit growth. Susceptibility is correlated with the density and size of stomates of various organs of different species in the following descending order: Citrus senensis, C. aurantium, C. lirnon and Poncirus trijolia.

利用柑桔不同品种的同样器官或同一品种同一株上不同部位以及不同发育时期的器官,作表皮組織結构的比較观察,証明气孔的形成及发育状态与柑桔潰瘍病的自然侵染(即非伤損侵染)有密切的关系。当柑桔枝梢生长到伸长停止期,枝叶上的表皮气孔的形成量为最大,此时达到最大的侵染,当枝梢停止生长后,枝叶表皮組織不再形成新气孔,原有气孔已漸老熟,此时便进入侵染的末期。徒长性枝梢的生长期較长,延迟了伸长的停止期,頂端不断形成新組織,而下部的組織已形成气孔,因此枝梢下部生长較久的茎叶先得病,而其頂部組織不受侵。果实的生长期甚长。在5月底至6月間果实的增长最快,形成气孔最多,故不断受侵染。当幼果生长60天左右,果实趋于定形,原有气孔已老熟,从此便絕少侵染。在器官上大量气孔形成时期如遇天旱,侵染便因病原菌的限制而減低或避免;如遇多雨时,侵染期可以延长。气孔分布最密的組織或器官最易侵染。品种間的抗病性亦与此有关,例如各器官的表皮气孔密度及气孔中隙的尺度均以甜橙为最高,順次为酸橙、檸檬及枳壳等。不产生气孔的表皮組織例如叶片的上表面不易受侵。伤損及人工接种可以使任何气孔形成时期受侵,說明突破表皮时便失去抗病力。但在自然情况下虫伤及其他損伤极易栓化,...

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...

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...

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。

1.以130只一个月雄性小鸡,将肱二头肌中1/3部切除,在机体内甲状腺素浓度不同条件下,观察了骨骼肌的再生恢复过程。2.正常小鸡的肱二头肌中1/3部被切除后,约在40—50天以内无论在外形上或组织学构造上都可达到相当程度的恢复。不过,在再生的肌纤维间仍存在着较多的纤维组织,而且新生的肌纤维粗细不一,排列也不规则。3.小鸡长期服用甲基硫氧嘧啶之后,在甲状腺素不足条件下,骨骼肌的再生恢后过程是非常缓慢地进行。损伤肌纤维的退化过程迟缓,而新的肌纤维又不能迅速形成。与此相反,结缔组织积极增生和分化,到了手术后20天就形成了致密的结缔组织瘢痕。此后,在外形上虽可恢复,但内部结构却多为纤维组织所充塞。直到70天后,损伤肌肉在构造上仍不能得到完全恢复。4.小鸡长期服用甲状腺素之后,由于处于代谢亢进状态下,骨骼肌的再生恢复过程迅速地进行。受伤的肱二头肌在外形上恢复的较快,新的肌肉成分在创伤里能迅速的生长和分化。因此,手术后40天的再生肌无论在外形上或在构造上都比前两组动物的同期再生肌要好得多。本组动物的损伤肌到手术后70天,可得到完全的恢复。
