ジャーナル フリーIn 34 cases with unilateral Bell's palsy which had both normal hearing and tympanogram of Type A, crossed SR was evaluated chronologically under the same stimulus range of sound pressure level by means of the oscilloscope to record the entire pattern of sound-induced waveform in addition to SR threshold. Amplitude, reflex contraction time (RCT) and reflex relaxation time (RRT) induced were set up for measurements as a parameter.
The present investigations are chiefly concerned with how these parameters, described above, change according to the time course of facial palsy, on one hand, and on the other hand, which parameters can be the best indicators to reflex the recovery of the paralysis.
Results obtained are as follows. 1. As for chronologic changes of SR parameters, on the paretic side, SR threshold decreases rapidly, amplitude increases, RCT is shortened and RRT is prolonged gradually according to the time course of facial palsy. 2. On the normal side, SR threshold increases, amplitude decreases and RRT is shortened gradually according to the time course of facial palsy. 3. RRT, on the normal side, is prolonged temporarily within 20 days after the onset of facial palsy. 4. Amplitude and RRT on the paretic side, and RRT on the normal side can be used for the prognostic diagnosis of facial palsy as the one of the best parameters to indicate the rcovery signs of facial palsy. 5. The function of stapedius nerve and muscle on the paretic side is reflected indirectly in SR parameters on the normal side. Therefore, if the time course of SR parameters on the normal side is investigated, the time course of the function of stapedius nerve and muscle on the paretic side can be made clear even before the restoration of SR.抄録全体を表示PDF形式でダウンロード (3087K) -

ジャーナル フリーThe relationships between thermograms and the physiological nasal conditions were inverstigated by thermography which indicates the temperature distribution of the body surface. It was cleared that the nasal thermogram indicated low temperature in subjects without nasal obstruction, on the contrary in those with nasal obstruction high temperature was indicated.
To clear such phenomenon, the naris was plugged with a cotton ball, and the nasal respiration was loaded. From the results, the temperature on thermogram was increased. This change was greater in hyperesthetic rhinitis than normal.
The nasal thermogram was rapidly creased after stimulation to hands with cold water and increased gradually until slightly over than before the stimulation and recovered in normal subjects. In hyperesthetic rhinitis, the patterns were divided into three types; unstabilized luctuation of temperature at 5-10 minutes after stimulation and followed by increased of temper ature (Type 1), no change of temperature (Type 2), decreased of temperature (Type 3).
From these results, it was cleared that the nasal thermogram was closely related with nasal obstruction, and with the autonomic nervous system which controlled the current of blood at nasal mucous membrane, because the fluctuation of nasal thermogram with stimulation of cold water and the fluctuation of the current of blood at nasal mucous membrane with same stimulation seemed identical.
Therefore, the techniques of nasal thermography seemed the useful method to clear the autonomic nervous system in the nasal cavity.抄録全体を表示PDF形式でダウンロード (2686K) -

ジャーナル フリーIn order to know the validity of allergic theory on Meniere's disease, influence of the antigen-antibody reaction on the guinea pig's labyrinth were investigated. This experiment was performed and confirming that carbon particles injected through the foram. stylomastoideum could reach the labyrinth.
Thirty-one guinea pigs were sensitized by horseradish peroxidase (HRP) for this experiments, and the product of antibody was confirmed by the immunological examination. On the other hand, 17 normal (non-sensitized) guinea pigs were used for the control study.
HRd was challenged through the foram. stylomastoideum to the left labyrinth of all guinea pigs.
In sensitized guinea pigs, horizontal nystagmus appeared to the right side (opposite side) about 15 minutes after challenging, and continued for 24 hours. This nystagmus was not observed in control guinea pigs except injecting dense HRP solution.
Guinea pigs were divided into three groups.
Group I was sacrified at 1 hour after challenging.
Group II was sacrified at 24 hours after challenging.
Group III was sacrified at 48 hours after challenging.
In group I and II, endolymphatic hydrops was not observed. But, particles of HRP were detected in the basement membrane of Reissner's membrane and marginal cells of the stria vascularis by electromicroscopy.
On the other hand, group III has already lost these HRP particles, but endolymphatic hydrops could be observed.
These findings were not observed in the control study, and suggested that the place of antigen-antibody reaction would be Reissner's membrane and stria vascularis. It was thought that hyperpermeability of Reissner's membrane and hypersecretion of the stria vascularis induced by the antigen-antibody reaction were probable cause of endolymphatic hydrops.抄録全体を表示PDF形式でダウンロード (2322K) -

ジャーナル フリーIn order to clarify autonomic dysfunction as a cause of Meniere's disease, the difference between the pupillary areas of both eyes, the light reflex test and mecholyl test by means of conjunctival instillation were examined in normal subjects and patients with Meniere's disease. The results obtained were as follows; 1. The difference in the pupillary area between both eyes was not found even at attack stages of Meniere's disease. 2. In the light reflex test, both the mean velocity of miosis and the velocity of miosis at the half contraction were slower in patients with Meniere's disease than normal subjects, however, they did not differ between the eyes of the affected and unaffected sides. This shows suppression of the contraction phase in patients with Meniere's disease. Shortend half dilatation time found on the affected side at the attack stage shows activation of dilatation phase. On the other hand, the mean velocity of half dilatation on the affected and unaffected sides were slower in patients with Meniere's disease at the interval stage than normal subjects, showing suppression of dilatation phase.
In summary, the patients with Meniere's disease seem to be under the condition with activated parasympathetic nerve at the interval stage and under the condition with suppressed parasympathetic nerve at the attack stage. 3. In the conjunctival instillation test with 5% mecholyl, patients with Meniere's disease showed high appearance rate of significant miosis. However, the appearance rate of abnormalities were higher and the affected- than the unaffected side at both the quasi-attack and attack stage. Furthermore, as the pathological stage advanced, the rate of contration (miosis) became higher in the same patients. 4. The advantages of the light reflex test and the mecholyl test were comparatively evaluated in the same patients. The results revealed that the mecholyl test is more sensitive than the light reflex test in detecting abnormalities in autonomic nerve system of the patients with Meniere's disease.
From these results, it was surmised that the suppression of parasympathetic nerve system on the affected side may play a role to involve attacks of Meniere's disease.抄録全体を表示PDF形式でダウンロード (1446K) -

ジャーナル フリーA closed technique of the middle ear surgery for cholesteatoma has been widely used because an open method has disadvantage to form a wide cavity and debris accumulation. However, elimination of the bony bridge is sometimes necessary for complete removal or debridement of the cholesteatoma matrix. In such a procedure, it becomes important to reconstruct the bridge which can protects postoperative retraction of the ear drum and succeeding so-called pocket formation. For the purpose of bridge reconstruction, we try to use sintered hydroxyl apatite ceramic.
Preceding the clinical application, an animal experiment was performed, that is, the apatite was embedded in the tibia of the rabbit and postoperative course was observed. The experiment revealed that the apatite did not cause inflamatory or foreign body reaction in the surrounding tissue and adhered strongly to the host bone and the covering soft tissue.
Following this animal experiment, we applied the porous apatite with 55% of pore rate, the same as used in the animal experiment, to the middle ear surgery. The apatite plate has a curvature to fit the external canal wall. After trimming of the apatite plate, it was inserted to the site of removed bridge and covered by fascia at the canal side. Mastoid cavity was obliterated by collagen sponges.
Our 1 and 1/2 years experience with the use of the apatite is limited to 16 cases. Although the follow-up on these cases was too short for final evaluation, the initial results showed a satisfactory condition without infection or extrusion. We propose that this material can be valuable in the reconstruction of bony defect in the external ear canal.抄録全体を表示PDF形式でダウンロード (1976K) -

ジャーナル フリーMembrane colors of inferior nasal turbinate and lower lip vermilion were measured by newly designed photoelectric colorimeter connected with selfoc needle scope as a senser.
Measurement was performed by way of Tristimulus Value Method under JIS-Z-8722 based on modern science of color. The subjects were 61 adults with ages from 19 to 45.
Chromaticity diagram was figured from tristimulus values of the subject color. Compared with the chromaticity diagram and the systematic color name recommended by international society of color council, it was found that membrane color of nasal turbinate belongs to yellowish or orange pink zone, color of lip belongs to pink or reddish pink zone. According to result from another measurement with Fast spectrophotometric colorimeter, absorption bandsaround 540nm to 576nm were found on specter of nasal turbinate and lip vermilion. Also forehead skin color showed similar spectral pattern. Since these absorption bands on wave length of the color well coincide with that of oxy-hemoglobin in blood stream, hemoglobin pigment always have large influence upon the membrane color or skin in human body. Measurement under ischemic condition with pressure upon the membrane and skin was also performed.
A bibliographical review of photoelectric colorimetry since 1978 was also included.抄録全体を表示PDF形式でダウンロード (2663K) -

ジャーナル フリーSince various types of tympanograms (T. G.) are obtained in the cases of otitis media with effusion (OME), it may be rather difficult to determine the actual pathophysiological states of the middle ear cleft by mean of impedance audiometry.
In this paper, we attempted to investigate how various types of T. G. are formed by experimentally modified middle ear clefts. The plastic models, the guinea pigs' middle ear bulla and the human temporal bone which is obtained at the time of autopsy, are used in the present experiments. The results; 1) B type of T. G. is often produced by an occlusion of the aditus-equivalent-site of the plastic models and of the epitympanic isthmus of the human temporal bone. 2) Even if the middle ear effussion is present in the mesotympanum, B type of T. G. is not detected in the plastic ear models, guinea pig and human middle ear specimens without blockage of the aditus-equivalent-site. 3) A blockage of the aditus as well as a diminution of the capacity-volume of the mastoid cavity are chief causatives of the pathological types of T. G. 4) The present experiments could not draw any conclusions about a question how does a viscosity of the effusion affect to the form of T. T. G. 5) Middle ear pressure is almost equivalent to the pressure at the peak of the compliance.抄録全体を表示PDF形式でダウンロード (675K)
