It has been found, that the extracts of different tissues (liver, spleen, muscles, kidney), made according to Filatov, are capable of stimulating adrenal cortex as judged by their ability to cause a decline in adrenal ascorbic acid after intraperitoneal administration into albino rats. But this adrenocorticotropic action requires the presence of an intact pituitary gland, that is to say, all the tissue extracts examined, contain an ACTH releasing factor, which stimulates the release of ACTH from anterior...

It has been found, that the extracts of different tissues (liver, spleen, muscles, kidney), made according to Filatov, are capable of stimulating adrenal cortex as judged by their ability to cause a decline in adrenal ascorbic acid after intraperitoneal administration into albino rats. But this adrenocorticotropic action requires the presence of an intact pituitary gland, that is to say, all the tissue extracts examined, contain an ACTH releasing factor, which stimulates the release of ACTH from anterior pituitary. It has been found, that the ACTH releasing factor is ultrafiltrable. The possible role of this factor in the regulation of anterior pituitary secretion of ACTH in stress and in clinical tissue-therapy is discussed.

以腎上腺抗壞血酸降低法證明不同的組織浸液(肝、脾、腎、肌)均具有興奮腎上腺皮質的作用,但此作用是通過腦垂體前葉ACTH的分泌而發揮的,在割出腦垂體的動物組織浸液即不再呈現作用。由於此組織浸液所含有的有效成份可以透過超瀘膜,故其可能為小分子的代謝產物。最後並將此實驗的結果聯系腦垂體前葉ACTH的分泌機制及組織療法的功效加以討論。

The action of Wave on vertical wall is one of the important problem. in wave theory. The invstigation of it is valuable not only because of the fiact that it will enable us to learn more deeply the important phenomena of the wave motion of the ocean. Since Sainflou established his theory of standing wave, many famous scientists have been waking researches on that problem. This problem should be studied not only theoretically and experimentally, but also should be studied in the light of experiences of the breakwater failures occured in the past. Therefore when-ever a failure of breakwater occurs in any part of the world, the investigatort attention will be at once taken upon it. On the 19th Feb. 1955, a great damage of the breakwater at port Genoa, Italy occured. At the suggestion of the Soviet specialist A. A. Kasparson(A. A. ), then working with us, a model test for investigating the cause of failure of breakwater at Port Genoa was conducted in our laboratory. After observing and analyzing many times the failure of breakwater in the process of this experiment, We find that it may be classified as concern to the phenomena of failure into two types, namely, types of long-wave failure and that of short-wave failure. As to the failure which occured at port Genoa, it belongs to the type of short-wave failure. In this experiment, the ware pressure on the face of the vertical wall has also been measured. Besides that, for the purpose of increasing the wall's ability to resist against long-wave failure, several tests of strengthening the stone bed near the harbour side are made.

波浪对直立堤的作用是波浪理论中的一个重要问题。这个问题的研究不仅是进行港口设计所必需的,而且还有助于我们深入地了解海洋中的波浪运动。 自从森弗罗(Sainflou)建立了他的立波理论以来,许多知名的科学家进行了这方面的工作。这今问题不仅是需要在理论上和在实验室内加以研究,而且还应该深入地去研究已经发生了的外堤破坏事故。因此一旦在某处发生这类的事故,就必然会引起各国科学家们的注意。 1955年2月19日,在意大利热那亚港发生了一件巨大的外堤破坏事故。那时苏联专家A.A.卡斯巴申(A.A.Каспарсон)还在我院工作,在他的建议下,在我们的实验室内进行了模型试验以研究热那亚港外堤的破坏原因。 在实验中,我们观察和分析了外堤的许多破坏现象,根据这些观察和分析,我们可以把破坏按其现象分成二类:即长波破坏和短波破坏。而热那亚港的破坏事故则属于第二类。 在这个实验中,我们还测了直立堤上的波压力。此外,为了增加外堤抵抗长波破坏的能力,我们还做了几个加强港侧基床的试验。

Chinese rape, varieties of Brassica campestris and B. chinensis and many cruciferous crops including radishes, but except varieties of B. oleracea, are generally affected by a mosaic disease, causing serious losses amounting occasionally to a death rate of over 90%, while an infection rate of over 30% is not uncommon.

Chinese rape, varieties of Brassica campestris and B. chinensis and many cruciferous crops including radishes, but except varieties of B. oleracea, are generally affected by a mosaic disease, causing serious losses amounting occasionally to a death rate of over 90%, while an infection rate of over 30% is not uncommon. The symptoms involved were vein-clearing, yellow or green veinbanding, typical mosaic, rugosity of leaf lamina, dwarfing and rosetting. They may appear in different combinations. Flower stalks may not come out or are shortened, deformed and twisted. Flowers appeared pale yellow and become abortive, or forming only small and twisted seed pod, which are sometimes spotted with black necrosis, and bearing small and deformed seeds. When the winter temperature is low, diseased plants may succumb first, forming missing hills. Late infections may result only in vein-banding of the upper leaves and partial abortion of the seeds. On several varieties of radish, mostly of the green type, which apparently are more resistant, only fine mottling appears on the leaves while infected. On varieties of B. napella, another oil-bearing group, the symptoms are entirely different (plate 1, fig. 5), appearing as systemic bright yellow spots on the leaves. Necrotic flecking can eventually be found at the center of these spots. Necrotic streaks and spots develop on the flower stalks and seed pods. Dwarfing and distortion occur on leaves, stalks and pods, and death may even be resulted from severe infections. However, this species showed certain degree of resistance to the disease in the form of late infection and the lower incidence of the disease. The viruses from different host plants are cross-inoculable, although some strains do not infect B. napella. None of them can infect the cabbage group by sap inoculation. 3 viruses were identified: differentiated by their physical properties and the host reactions they induced (Tables 1 and 2 for the viruses 1 and 2): 1. Thermal inactivation below 70℃. 2. Producing necrotic local lesions only on N. tabacum var, "Nungling 400" …… virus 1 2. Producing necrotic local lesions and systemic mottling on the same host……virus 2 1. Thermal inactivation above 90℃., necrotic local lesions on N. glutinosa…… virus 3 The first two viruses can be subdivided into 2 strains each by their ability to infect B. napella. Virus 1 is considered to be a strain of Brassica virus 2 or the Turnip mosaic virus; from the type, it differs in not infecting the cabbage group. Virus 2 is identified as a strain of Cucumis virus 1 or the Cucumber mosaic; virus; from the type, it differs in having lower thermal inactivation point (55℃.), lower dilution end point (1: 1,000—3,000); and shorter longevity invitro (2 days), in producing local lesions on tobacco, and in that the typical strain of Cacumis virus 1 gives only a partial protection to this strain on tobacco. The 3rd virus was less studied. It shows affinity to Nicotiana virus 1 or the tobacco mosaic virus. A limited test showed that the first virus was the only virus found present in the field in 1957. An analysis of 17 isolates of virus from the Chinese rape, exhibiting various syndromes of symptoms in the field, gave an Unanimous result in host reactions, indicating that these isolates belong to a single virus. Virus 1 was found to be easily transmitted by sap, by aphids, including peach aphid (Myzus pcrsicae), false cabbage aphid (Rhopalosiphum pseudobrassicae), and cotton aphid (Aphis gossypii). In insect relationship, the virus belongs to the nonpersistent group, a single feeding will enable an active transmission of about 20 minutes. Peach aphid seems to be an effective vector that 2 or more viruliferous aphids per plant are capable of 100% transmission. The virus is not seed-transmitted. Fresh residue of diseased plant in the soil may cause occasional infection of the replanted plants. The virus can infect several cruciferous weeds, but, among them, only Rorippa montana (wall.) Small grows all the year round and possesses a perennial crown. It is also foundto be commonly infected in the nature. Rubbing with infected sap or using aphid as vector, the virus from this weed can easily be transmitted to the Chinese rape, producing the typical mosaic symptoms. This weed, therefore, seems to be capable of beoming a source of inoculum for the primary infection of the Chinese rape.

南京及华东地区的油菜与十字花科蔬菜普遍发生花叶病。病原病毒經抗性(失毒温度、稀释終点、体外保毒期)測定和寄主反应測定,认为可以分作三大类型:分别为芸苔病毒2号,黄瓜病毒1号与烟病毒1号的株系。前两种病毒都能为害油菜、大白菜、白菜、芥菜、蘿卜等,但不为害甘蓝型的蔬菜,并都能引起菠菜和茼蒿的花叶,和在烟上引起局部枯斑。第一型在烟农特400号和心叶烟上不引起花叶,而第二型在烟和心叶烟上都能引起系統性花叶。第一型不为害心叶烟,而第三型可在心叶烟上引起小枯斑。第一型与凌立、楊演的油菜花叶病毒相近似,而和范怀忠、柯冲从十字花科蔬菜中所分离出的分离物1号最为相象。与裘維蕃、王祁楷在白菜上所发現的孤丁病毒的差别,在于不能侵害甘蓝类的蔬菜。第二型病毒与范怀忠、柯冲的分离物3号相近似,但与典型的黃瓜花叶病毒仍具有一定的差异。这些病毒在油菜上所引起的症状却沒有明显的差別。1、2两个类型的病毒都有一部分能为害早生朝鮮型的油菜,引起系統性黄斑及枮斑,病重的也能早期死亡。大田中的油菜病株的病毒,大多属于第一型病毒。病毒主要由桃蚜和蘿卜蚜传染,病毒系非持續性的,蚜虫一次吸毒后,传病期不超过20分钟。两个以上的桃蚜传病率就可达100%。种子...
