Sequential clinical and hematological examinations were carried out during thermal loads on the steers, and pathological examinations after their death or slaughter. All the steers manifested panting, rise of rectal temperature, reduction or disappearance of peristalsis, hypersalivation, dysfunction of the skin reflex, and remarkable decrease in white blood cell count and pressure of CO2 (Pco2) value of jugular blood. At the end of heat stress, an animal would be survived if it meet the following conditions: (1) rectal temperature was below 42.7 degrees C, (2) the respiration rate did not decrease to one half (about 100/minute) of the maximum rate during the exposure period, (3) peristalsis and skin reflex disappeared almost completely, (4) the white blood cell count did not decrease to less than 50 per cent of the normal level, and (5) the Pco2 value of venous blood was maintained at a level of more than 15 mmHg. Cloudy discoloration with a boiled-meat appearance was noticed in the skeletal muscle of the hind part of the body in two dead cases. No significant changes were detected in any other steer slaughtered several days after release from the thermal stress.","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"20 4","pages":"138-47"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17843823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sulfur granule of actinomycosis was large, and oval or horsehoe-shaped. In it, there were a number of gram-positive, filamentous or short rod-like hyphae beneath clubs. Ultrastructurally, the center of the sulfur granule was composed of a cluster of hyphae, and the periphery was surrounded by clubs arranged radially. The clubs were made of electron-dense fine granules and had a degenerated hypha at the center. These granules varied in amount from small to large. As for the host reaction, neutrophil infiltration appeared first around the sulfur granule. Then epithelioid cells proliferated and phagocytized hyphae. Finally, proliferating fibroblasts enclosed them and formed tiny granulomas. The sulfur granule of actinobacillosis was small and lobulated. In it, a number of gram-negative, short rod-like bacteria were present beneath clubs. Ultrastructurally, the center of the sulfur granule contained intact or degenerated bacteria, and the periphery was composed of radially projecting clubs. These clubs were made of electron-dense amorphous material, in which several layers of tubular structures surrounded the bacterium conentrically. The host reaction was almost the same as that of actinomycosis. The proliferation of fibroblasts was prominent. There was a strong tendency for these cells to form many tiny granulomas.","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"20 2","pages":"53-9"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18453696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight of the affected cattle were divided into two groups from the results of some examinations. Radiographical changes, such as the deformation, atrophy and lack of the apex of the third phalanx, were remarkable in five affected cattle (Nos. 1, 2, 4, 5 and 6; group A), but not so remarkable in three (Nos. 7, 8 and 9: group B). The blood composition was within a normal range in group A. On the other hand, total serum protein, urea nitrogen, calcium and inorganic phosphorus were a little lower and magnesium and potassium higher in blood level in group B than in control cattle. The pH of rumen juice was within a range of 6.0 to 6.5 in all the effected cattle. The differences of components of phalanges were remarkable between the two groups. Namely, in group A, the magnesium and sodium levels of phalanges were higher than in control cattle. Ash and calcium contents increased distinctly at the tip of the third phalanges were higher than in control cattle. On the other hand, in group B, ash, calcium, sodium and potassium contents were lower than in control cattle. The fat content was much higher in the affected groups than in the control group. There wer slight changes in the inorganic component levels of the ungual layer. These changes were proportional to those of the phalanges.","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"20 1","pages":"23-9"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18443644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Mouth breathing in chickens under rebreathing conditions, cervical vagotomy of heat load.","authors":"T Itabisashi","doi":"","DOIUrl":"","url":null,"abstract":"By recording the lower beak movement, open-mouth breathing was monitored in adult hens restrained in a supine position with the cannulated trachea under rebreathing conditions, bilateral cervical vagotomy or heat load. Tidal volume and respiratory carbon-dioxide and oxygen contents were recorded simultaneously. The beak movement can be a significant indication of hypercapnia and/or increase in respiratory CO2 content, but not of hypoxia or decrease in respiratory O2 content. Vagotomy causes big oscillatory movements of the beak, which do not mainly depend on hypercapnic hypoxia induced by the vagotomy. If the dysfunction of the vagus is aggravated progressively, it will be unable for the pattern and amplitude of beak movement to be any differential indication of this dysfunction from hypercapnia and/or increase in respiratory CO2 content seen at respiratory failure. Two patterns of beak movement are noticed. One appears at an early stage of beak movement and at a certain direct level superimposed with or without small beak-oscillation. The other indicates a bigger oscillatory beak movement than the former. This oscillatory movement is synchronous with the inspiration after vagotomy and hypercapnia. This is the case with hyperthermia at a remarkably high breathing frequency. The amplitude of beak movement is not always proportional to the tidal volume. The onset and end of inspiration cannot precisely be indicated by those of a beak movement.","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"20 4","pages":"148-60"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18279609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They were subjected to passage in splenectomized calves 4 approximately 8 months old by the infectation of infected ticks or the inoculation of infected blood. As a result, the average of incubation of the Japanese strain was proved to be 23 days by the tick infection and 21 days by the inoculation of infected blood stored in a frozen state. The rate of detection and the average size of various forms of Theileria in the proliferative stage of the Japanese strain were as follows: Comma-shaped and bacilli forms, 86.8%; bacilli from 2.15 x 0.73 micron; oval and spherical forms, 11.3% and 1.97 x 1.22 and 1.46 micron, respectively; tetracoccal form and anaplasma-like form, 0.9 and 1.0%, respectively, and 0.54 micron in diameter. The highest parasitic rate of the Japanese strain was 11.9% on the average, and the rate of decrease in erythrocyte count 70.6% on the average. Rods were seen in protozoa particularly rich in cytoplasm. Such symptoms as pyrexia, depression, and anorexia appeared as Theileria propagated. No hemoglobinuria occurred or no schizonts were detected. Essentially the same results were obtained from the Russian strain as from the Japanese. Besides, Haemaphysalis longicornis produced in Japan acted also as a vector for the Russian strain. There was a good serological agreement between the Japanese and the russian strain in the results of the cross complement fixation test and the cross indirect fluorescent antibody test. There was no difference in the results of the complement fixation with the eight strains of the Japanese strain.","PeriodicalId":76197,"journal":{"name":"National Institute of Animal Health quarterly","volume":"20 2","pages":"44-52"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17829762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
