In the previous report (Journal of the Japanese Society of Veterinary Science, Vol. IV, No. 1) the author called attention to the precipitin reaction regarding the differential diagnosis of bovine contagious pleuro-pneumonia. In the experiment which he has made later on, he used as precipitin the serum obtainee from affected cattle or calves infected by inoculation with the virus, and found that the precipitin serum prepared in this way was not fit for use, because the normal cattle serum may sometimes contain precipitin. For this reason he intended to get a precipitin serum from rabbit and found it very suitable for the object.Preparation of precipitin serum: From a horse-serum-broth-agar slant culture of the virus kept for 10 days in an incubator at 70°C., an emulsion was prepared with 20c.c. of physiological salt solution (precipitogen). One half (10c.c.) of this emulsion was injected into testicle and the other half into thoracic cavity of a rabbit. At an interval of 4 days, the injection was repeated in the same way, and after 15 days the serum was taken from the animal and tested upon precipitin, as shown in the following table, the results being read after one hour at room temperature (10-15°C.).Precipitation experiments have been made in 4 cases of naturally affected cattle, 9 cases of artificially infected calves and 57 cases of controls. The results obtained are shown in the following table:It must be noted here that in the precipitation experiment, all 4 cases of the affected cattle gave positive reaction in a dilution of from 1:640 to 1:1280 and all 9 cases of infected calves inoculated with the virus the same result in a dilution of from 1:40 to 1:1280, while cases of pericarditis (1), pleuro-pneumonia (1), tuberculosis (1), and influenza (1), as well as 53 cases of controls gave negative results.

A certain pustulous skin disease has long been recognized as an epizootic disease among swine in this country and there have been often severe outbreak of this disease since 1917. This disease appears epidemically in early summer and late autumn. The swine seems to be most predisposed. The eruption may occur without fever or any trouble of health, and there have been often observed some cases of chronic form, in which affected animals happened to die of cachexia. Our knowledge regarding the causal agent had been far from complete till my attention was directed to the study of it.

In the previous number of this journal (Vol. III, No. 3), Matsuba, one of the authors, published the first part of this experiment under the article "On the effect of castration upon the thyroid gland, hypophysis, thymus and adrenal in the albino rat." This paper is the second part of the same experiment, dealing with the growth of various organs and the effect of castration upon them excluding endocrine organs.The material used included 300 rats of male sex, varying from newborn to 300 days of age. The 300 rats were all raised up in our laboratory and divided into 500 lots according to litter and age. One to three rats from each lot which consisted of three to eight rats were fed as controls.All the rats excepting the controls were castrated on the 15th, 30th, 40th, 50th, 60th, 75th, 90th, 120th, and 150th day of age and killed with controls at an interval of about 30 days, extending from 60 days to 300 days of age.During the course of experiment all the rats were weighed every other day and the organs to be examined were obtained immediately after the animal were killed and then precisely weighed.The results obtained from the experiment can be summarized as follows.1. The post-natal growth of the castrated rats was in a fair agreement with that of the controls. No remarkable increase was observed in the body weight of the castrated animals; the fatty condition of the animals employed, possibly due to lack of proper feeding and management, might have caused no difference in the body weight of the castrated and the centrols.2. No effect of castration was observed in the body weight of rats, but the tail length of the castrated animals increased by 5% on an average.3. The hearts of the castrated animals develop as good as those of the controls before 180 days of age, but hereafter they showed decrease in their development. A decrease has also been found in the growth of hearts of animals castrated in younger age than those operated in advanced age.4. The weight of kidneys was less by 20-30% in the castrated than in the controls. In the weight of liver no effect of castration was observed. The spleen of the operated was all heavier than that of the control during a certain course of time after castration, but in the operated animals a decrease was found in its weight after 200 days of age.5. The effect of castration upon the length of long bones was quite remarkable; they have been found especially shorter in the animals castrated before 60 days of age. As in the case of the length, the weight of the long bones was also much less in the animals operaied before 60 days of age.6. The better was the deposit of calcium in the bone, the later the castration was performed. As regards the P and Mg contents in the bone no difference has been constated between the castrated and the controls.7. The resistance of long bones against the artificial fracture seemed to decrease due to castration. The femor was weaker in the animals operated after 60 days of age a

A number of investigations with regard to correlations usually assumed to exist between hemorrhagic septicemia organisms has hitherto been published, but it is at present yet impossible to differenciate them with distinction, as the results obtained by those who have worked with the organisms are not in agreement.Employing B. bubalisepticus, B. suisepticus, B. avisepticus and B. bovisepticus I have made some experiments in connection with these problems and came to the following conclusions:1. Morphology, growth on ordinary culture media, indol production, hemolytic property, bacteriolysis in bile, fermentation test etc. showed no satisfactory evidence as to their identification.2. No distinction could be obtained from their pathogenicity for mice, rats, guinea-pigs, rabbits and pigeons inoculated or fed with the organisms and also from the postmortem appearances of the experimental animals.3. Cross agglutination test employing an immune serum obtained from the rabbit inoculated with dead organisms showed that the correlation between the organisms is highly complicated and no specificity could be distinguished in any of them. Agglutinin absorption test gave likewise no satisfactory results, although when employed an immune serum from the guinea-pig inoculated with living organisms the occurence of group reactions was less remarkable and consequently in a certain organisms specificity could be distinguished. Complement fixation test with those sera showed there are so many group reactions that no specificity could be found in any of the organisms. If, however, the complement fixation titres were taken into consideration the organisms could be specified in more or less noticeable degree, but not satisfactory enough for the identfication of them.4. Active and passive animal protection tests with mice showed in no case so markedly a specificity as to enable us to identify the organisms.Briefly speaking, it may be assumed that some of hemorrha- gic septicemia organisms may have their specificity, but it is quite impossible to differenciate them by virtue of the specificity which is generally so undistinguished.
迄今为止，已经发表了一些关于通常被认为存在于出血性败血症有机体之间的相关性的研究，但目前还不可能区分它们，因为那些与有机体一起工作的人获得的结果并不一致。我利用bubalisepticus, B. suisepticus, B. avisepticus和B. bovisepticus就这些问题做了一些实验，得出以下结论:形态学、在普通培养基上的生长、吲哚的产生、溶血性能、胆汁中的细菌溶解、发酵试验等对其鉴定都没有令人满意的证据。对接种或喂食这些微生物的小鼠、大鼠、豚鼠、兔子和鸽子的致病性，以及实验动物的死后外观，都没有区别。用接种过死菌的兔免疫血清进行交叉凝集试验，结果表明，死菌之间的相关性非常复杂，没有特异性。凝集素吸收试验同样没有令人满意的结果，尽管当使用接种了活生物体的豚鼠的免疫血清时，群体反应的发生不那么显著，因此在某些生物体中可以区分特异性。对这些血清进行的补体固定试验表明，有太多的群体反应，在任何生物体中都找不到特异性。然而，如果考虑到补体固定滴度，这些生物或多或少可以在明显的程度上被指定，但不足以令人满意地识别它们。在小鼠身上进行的主动和被动动物保护试验没有显示出明显的特异性，使我们能够识别出这些生物体。简单地说，可以假定某些出血性败血症菌可能具有其特异性，但由于通常无法区分的特异性，因此完全不可能区分它们。

In recent years, especially in summer time, infectious pneumonia has been very prevalent among lambs of the Government Sheep Farm at Tomobe (Prefecture Ibaraki), causing great losses every year. The results of our investigation on the disease are summarized as follows:At post-mortem of animals dead from the disease were demonstrated severe anaemia owing to numerous nematodes in the stomach and intestine, pneumonia catarrhalis purulenta lobaris (part of middle lobe, and outer half of anterior and posterior lobes affected) with pleuritis fibroplastica. The histological examination of the affected part of lung revealed hyperaemia, desquamation of alveolar epithelium, exudation of serous fluid, large mononuclear cells and leucocytes in alveoli, leucocytic and lymphocytic infiltration as well as connective tissue production around the bronchioli.From the affected areas of the lung were isolated Bacillus pyogenes, Bacillus ovisepticus, a small Gram-positive bacillus, Micrococcus catarrhalis, a streptococcus, and a staphylccoccus, of which the first three organisms are to be considered most significant for the disease in view of high percentage of their occurrence in pulmonary lesions, their great virulence for the lamb and laboratory animals, and of intimate immunological relations between these organisms and the serum of affected lambs.As the mixed vaccine prepared from these three organisms gave a good result in laboratory animals and a few lambs treated, double treatments with the vaccine were practised this year on the Government Sheep Farm where the administration of vermifuges was enforced at the same time. As the result of the prophylactic measures cases of the disease and losses to the Farm were less than one-tenth those in the previous years.
