ジャーナル フリーAn outbreak of swine toxoplasmosis occurred in a hoggery in Shizuoka Pre-fecture. In the hoggery, pigs had been fed soil with pig-feed for 3 consecutive days from1 week before the outbreak of the disease. Toxoplasma oocysts were detected directly fromthe soil in the hoggery.A combination (Metlaod III) of ultrasonic treatment and sugar floatation method gavesatisfactory results. Moreover, the isolation of Toxoplasma was established by the in-oculation test on mice with the suspension of oocysts collected by Method III. Therefore, the causal agent of swine toxoplasmosis in the hoggery was the Toxopalsma oocyst foundin the soil examined. It was indicated that Toxoplasma oocysts played an important rolein the transmission of toxoplasmosis in natural conditions.抄録全体を表示PDF形式でダウンロード (604K) -

ジャーナル フリーThe boar testes which produced the so-called "multiple headed spermatozoa"in not negligible numbers, when with normal ones (Kojima et al.: 1973, 1974), NVCIC surveyed by means of the electron microscope.In the results of a few nunnbered sets, plural sperms coexisting within a serial plasnaamembrane were apparently proven with tlae micrographs of the cross, oblique and longitudinal sections. They were varied in number from double to octad sperm sets int partialprofile of sperm morphology in a common plasma membrat?e.The new name "multiple sperm syncytium" is postulated for this case by the presentauthors, and it is proposed to be added to the classification of sperm abnormalities, asa new type, on farm animals.Furtlaermore, some abnormalities of the sperm components already reported by Linepioneers were also represented with brief discussion.抄録全体を表示PDF形式でダウンロード (6169K) -

ジャーナル フリーThe development of viral antigen detectable by the fluorescent antibodytechnique and the production of infectious virus were studied iua Vero and E. Derm(NBL-6) cells infected with equine arteritis virus. In both cells the latent period lasted10 to 12 hr, followed by an exponential increase of infectious virus, and the peak Literwas reached 16 to 24 hr after infection. Viral antigen appeared as a small number ofgranules in the perinuclear region of the cytoplasm as early as l0hr after infection ina few cells. Fourteen to 16hr after infection, viral antigen filled the cytoplasm. At 24hr, cell rounding was found in fluoresced cells and some cells became detached from the glasswall. Viral antigen was detected exclusively in the cytoplasm. Although the above find-ings were common in both cells, the intensity of fluorescence was stronger in the E. Derm(NBL-6) cells than in the Vero cells.抄録全体を表示PDF形式でダウンロード (1033K) -

ジャーナル フリーComparative studies were made on blood coagulation in clinically healthycattle and cattle affected with experimentally-induced bracken poisoning by recordingthrombelastograph (TEG). It took 3 hours to record a TEG in normal cattle. The normalrange (mean +s.d.) of the thrombelastogram obtained from a group of 11 healthy cattlewas as follows. r: 15.4+2.2, K: 4.9+l.1, rfK: 20.3+2.7, ma: 80.5+2.4 and me: 420.O+65.0. The TEG of three calves fed bracken exhibited a prolongation or r, K and r-[Kvalue and a reduction of ma value in the initial stage. In addition to these findings, themshowed an extraordinary pattern in which post-maximal thrombus relaxation was nearlydiminished, in the hemorrhagic and the serious stage. This pattern can be explained bythree conditions, thrombocytopenia, an increase of fibrinogen and an increase of heparinlike substance in blood level, occurring in bracken poisoning.抄録全体を表示PDF形式でダウンロード (707K) -

ジャーナル フリーGuirxea pigs infected witlt Angiostrongylus cantonensis were examined forthe occttrrence of antigen sensitixe lymphocytes in variotns lymphoid organs (cervical, mediastinal and mesenteric l)mph nodes, and spleen), as assessed by in vitro incorpora-Lion of tritiated thymidine by lymphocytes following stimulation by adult or young adultworm antigens.Only splenic cells from infected guinea pigs showved significant blastogenic responses toboth adult and young adult worm antigens throtughout the course of infection. Thisresponse gradually increased as the infection progressed.Homocytotropic reaginic antibody was first detected 18 days postinfection and continu-ously demonstrated in some individuals throughout 18 to 47 days postinfection. However, the production of reaginic antibody was observed in only 50% (5/10) of the infectedanimals.No hemagglutinating antibody could be observed in the infected animals during thecourse of infection.抄録全体を表示PDF形式でダウンロード (733K) -

ジャーナル フリーTlae existence and the distribution of the Nymph vessels in the t?amstertestis were studied morphologically in detail. By the perfusion metlaod for fixation, theNymph vessels were observed in the interstitial tissue just adjacent to the seminiferotustubules with tire light and electron microscope.The penetrating of the Nymph vessels through the albuginea testis was confirmed andas a result of tracing these Nymph xessels, the coarse net works of the Nymph capillarieswere reconstructed and figured. The lymphatic net works were recognized to anastomoseeach other and their branches were situated just close to the seminiferous tubules and tlaeinterstitial cells. In the electronmicroscopic observation, these Nymph capillaries sltowedthe closed s)stem and so their free endings were not opened.The tissue spaces had no direct communication to the Nymph capillaries but they weresuggested to form the sinusoidal pathways of the same protein-rich liquid as that in theNymph vessels, and the important role of the interstitial tissue spaces as the passages orextracellular liquid were discussed.抄録全体を表示PDF形式でダウンロード (5640K) -

ジャーナル フリーDevelopmental processes of omasal motility under normal feeding conditionwere studied. Two male Holstein calves were rumenfistulated at an early age. Intra-luminal pressure changes in the reticulum, and the omasal canal and body were recordedsimultaneously on kymographic paper at regular intervals beginning at 2 or 3 weeks ofage.Cyclic contractions of the omasal canal which coincided with those of the reticulumwere first observed at 4-6 weeks of age. Contractions of the omasal body began to berecognized at 8 weeks of age. When the contraction of the omasal body was first observed, it showed a slow and irregular pattern. With the advance in age, it increased slowly infrequency and became more periodic. Then such a contraction of the omasal body ascould be seen generally between diphasic contractions of the reticulum in adult cattlewas first observed at 29-32 weeks of age.抄録全体を表示PDF形式でダウンロード (469K) -

ジャーナル フリーThree experiments were conducted to make clear the function of ingestatransfer in the omasum of calves. In Experiment l, ingesta transfer from the reticulumto the omasum was studied. An elastic tube was inserted into the reticulo-omasal orificethrough the omasum fistula. Outflow of ingesta from the reticulum through the tube wasobserved immediately after the second contraction of the reticulum. Furthermore, simultaneous pressure recording in the reticulum, rumen and omasal canal showed a rapid, pronounced drop in pressure of the canal at the time of the second contraction of tlaereticulum.Nut Experiment 2, auscultation on the body surface of the omasum was carried otzt.Flowing liquid sounds began to be heard periodically at 4-6 weeks of age. They wererecognized immediately after contraction of the omasal canal and about 12 seconds aftercontraction of the reticulum, although no sounds coutld always be heard in each reticularcycle. In Experiment 3, ingesta transfer from the omasum to the abomasum was studied.FIOW of ingesta into the abomasum was recognized about 12 seconds after contraction ofthe reticulum by visual inspection through the abomasum fistula. From the results ofExperiments 2 and 3, it can be considered that the flowing liquid sounds are attributableto the ingesta transfer from the omasum to the abomasum by the contraction of theomasal canal.抄録全体を表示PDF形式でダウンロード (790K) -
