摘要:

The interaction of vestibular and optokinetic nystagmus (OKN) was investigated by applying periods of ipsi- and contradirectional optokinetic stimulation during per and postrotatory vestibular nystagmus in healthy humans. Slow phase velocity and cumulative eye displacement of OKN was enhanced by vestibular nystagmus beating in the same direction and decreased by contradirectional vestibular nystagmus. A distinct correlation between the intensity of vestibular stimulation and the modification of OKN could be demonstrated by averaging the responses obtained in different subjects. On the other hand there was also a modification (enhancement or decrease) of vestibular nystagmus slow phase velocity by preceding OKN. Considering the intensity of these modifications, large interindividual differences were observed.

摘要:

Vestibular decruitment is a phenomenon characterized by the presence of less intense responses following stronger vestibular stimulations, and its presence has been considered as indicative of central vestibular pathology. In this study conducted in 24 normal individuals, with normal caloric responses, decruitment was observed in 58.3% of the cases. These decruitments were of types I and II as defined by Torok. Type III decruitment was not seen in these patients. In view of the present findings the actual meaning of the phenomenon must be investigated in larger numbers of patients with peripheral or central vestibular disorders.

摘要:

Vestibular decruitment is a pathological finding which indicates retro labyrinthine disease. In the overwhelming majority of cases, it is consistent with posterior fossa pathology. Weak and strong caloric stimulations must be applied with precision for detecting decruitment. Air-caloric stimulation has inherent limitation in regards to reproducing the strength of the stimulus. Thus, it is inadequate for decruitment detection. It is, therefore, advisable to use water-caloric testing to assess vestibular decruitment or recruitment as one of the most revealing diagnostic clues in our neurotologic armamentarium.

摘要:

Tonsil lymphocytes are labeled in vitro by l4C-thymidine and, respectively, 14C-uridine. The cells are separated by E-rosetting technique, and the fractions are characterised as B and T lymphocytes. Specific radioactivity was highest in the B lymphocytes, and large lymphocytes are enriched in this fraction. The B lymphocytes are located in the germinal centres, the perinodular tissue contains T lymphocytes. The results indicate a selective proliferation of B lymphocytes in the germinal centres.

摘要:

The relation of the infected to nephritis, rheumatic and heart diseases has been recognized but that to dermatoses has not been fully established nor applied clinically by dermatologists or otolaryngologists in the treatment of such patients. In order to assess the attitude of dermatologists as regards the dermatoses due to focal tonsillar infection, a questionnaire was sent to the departments of dermatology of 72 universities in Japan: 44 (61.1%) have replied. There were 40 dermatoses listed as possibly associated with a focal infection. About 60% of the universities endeavoured to detect the focus although the focus was not always removed when identified.

摘要:

Ultrasonography is a useful diagnostic tool in the evaluation of patients with paranasal sinus disease. It is a simple, reliable method with a failure rate of approximately 10%. The increasing use of this diagnostic tool requires the reemphasis and prevention of possible errors in establishing the correct diagnosis.
