摘要:

Presence of immunoglobulin A (IgA) and of secretory component in epithelial cells and in the lumen of the human endolymphatic sac was demonstrated by two different immunohistochemical methods. IgA was also detected in perisaccular plasma cells. The findings connote the existence of a local immune system of the inner ear.

摘要:

Free-floating cells (FFC) in endolymphatic sac (ES) were microscopically examined, counted, and statistically studied in 8 squirrel monkeys after the unilateral section of the utricular nerve (UNS). After the operation these monkeys were kept for 17–38 days until the acquisition of functional (locomotor balance) compensation was completed. The result showed twice more FFC in the ES on the operated side, than those on the nonoperated side. The result showed a significant increase (p < 0.05) of FFC in the ES under the pathological condition with autogenous debris in the endolymphatic space, and proved the existence of some reactive role of the ES to the labyrinthine insul

摘要:

Guinea pigs were used in this study. Physiological saline, india ink, and Staphy-lococcus aureus were injected into the cisterna magna, and S. aureus was also injected into the scala tympani. Changes in the microstructure of the cochlear aqueduct were observed by light microscopy and also by scanning electron microscopy, mainly by means of fracture preparations. From these experimental results, it could be confirmed that the periotic duct tissue of the chochlear aqueduct reacted especially to bacterial infection.

摘要:

The number of saccades, vestibular gain and visual suppression as a function of smooth pursuit gain were determined in 10 cerebellar cases. Visual suppression increased and the number of saccades decreased with increasing smooth pursuit gain while a high vestibular gain was found in most cases but without relation to the gain of smooth pursuit. An eye-motor model is presented according to which all findings could be related to a disturbance of proper cerebellar processing of optic impulses and of impulses to the vestibular nuclei in the parame-dian reticular formation.

摘要:

The influence of the predictive adaptability on saccades was studied in 20 normal subjects ranging in age from 18 to 43 years. The average velocity of random and constant saccades showed almost the same results. The maximum velocity of constant saccades was slightly faster than that of the random saccades. The latency of the random saccades was shorter than that of the constant ones. Thus, the predictive adaptability of the stimuli has little influence on the maximum velocity and on the latency of saccades in normal subjects.

摘要:

This paper studied the incidence of secretory and chronic otitis among a random group of 5,950 children, aged from 4 to 9, coming from four different climatic regions of Spain, and including a group of Gypsy children. Each of the children was given a questionnaire regarding socio-economic and environmental situation and pathological antecedents; the results for sick and normal children were then statistically analysed. The most significant aetiological factors to emerge were: low economic level, prior respiratory infection, climatic conditions, cases of rhinosinusitis and acute otitis, and family history. Among Gypsy children a much greater incidence was observed, due not to racial origin but to the greater incidence of the factors cited above.

摘要:

The desquamation and squamotransformation of rhinomucosa is described in 10 patients who developed typical atrophic rhinitis later. It may be considered a prodromal sign of atrophic rhinitis, and may be helpful in early diagnosis.
