Study on staining methods for mast cells in the nasal mucosa.

Mast cells are widely distributed in various organs. Two classes of mast cells, the mucosal mast cell (MMC) and the connective tissue mast cell (CTMC), have been shown to exist in the intestine of experimental animals. In the present study, we investigated the method of staining suitable for observing the mast cells distributing in the nasal mucosa, and also examined by the use of two fixatives whether the mast cells have properties of MMC or those of CTMC.

[A case of double bronchogenic cysts in the mediastinum].

A 42-year-old house wife had suffered from abnormal mass lesion in the right pulmonary hilum on her chest X-ray film. MRI showed another mediastinal mass between IVC and descending aorta with high T1 and T2 intensity. Thoracic CT done before MRI missed the latter lesion because only upper mediastinal scanning had been performed.

Sneeze-evoking region within the brainstem.

The neuronal mechanisms of sneezing were examined in precollicular-postmammillary decerebrate cats. Mechanical stimulation (frequency 20 Hz, peak-to-peak displacement 0.5 mm) of the nasal membrane evoked a series of sneezes.

[Pacemaker implantation in 7 days or less old of early neonates].

We have implanted cardiac pacemaker (PM) in 3 early neonates ranging from 5 hours old to 7 days old of age with congenital complete or incomplete AV block. They were in advanced stage of rapidly developed cardiac failure with resistance to drug therapy and with ventricular tachycardia or fibrillation. Cardiac failure was improved immediately in the 3 cases after the operation and the effectiveness by the pacing was recognized for a long term observation (4 months to 2 years).

[A case report of pulmonary arterio-venous fistula complicated with hereditary hemorrhagic telangiectasis].

A 5-year-old girl with multiple pulmonary arterio-venous fistulae was reported. Both her mother and grandmother have been diagnosed as the same disease previously. Her grandmother was treated with resection of the right basal segment for arterio-venous fistulae.

[Successful surgical treatment of infective endocarditis complicated with DIC and intracerebral hemorrhage].

This is a case report of a 61-year-old man, suffering from infective endocarditis of mitral valve in association with DIC and intracerebral hemorrhage. He was treated symptomatically and conservatively for 80 days after the onset of the DIC. His multiple cerebral hematomas gradually disappeared 2 months after conservative management.

[A successful surgical treatment of acute dissecting aneurysm of the ascending aorta: repair of the proximal intimal tear necessitating bypass for the right coronary artery].

This is a case report of the successful surgical treatment of acute dissecting aneurysm of the ascending aorta. The patient was a 65-year-old female, who admitted to the hospital 3 hours after the onset of severe back pain. Enhanced CT of the chest and abdomen revealed acute dissection of the ascending aorta from its origin to the bilateral common iliac arteries.

Possible role of plasma neurotensin in regulating the excitatory neural control of the rectum of the fowl.

Effects of neurotensin (NT) applied via the blood vessel on the responses to stimulation of Remak's nerve (RNS) were investigated in the chicken isolated and perfused rectums. NT (5 ng-2 micrograms/ml) produced a concentration-dependent inhibition of the constituent contraction but not relaxation of the responses to RNS. In addition, high concentrations of NT (over 80 ng/ml) produced a contraction of the rectal muscle.

[Emergency aortic valve replacement in active infective endocarditis in a chronically hemodialyzed patient].

A 36-year-old housewife, who had been treated with hemodialysis for 15 years is reported. She had suffered from active infective endocarditis of the aortic valve caused by blood access infection for several weeks. She rapidly fell into severe cardiac failure.

[Evaluation of the efficacy of ceftriaxone in acute suppurative otitis media and acute exacerbation of chronic suppurative otitis media. A comparative study with cefotiam as the control].

In order to objectively evaluate the efficacy and the safety of ceftriaxone (CTRX) using once daily administration of 1 g to cases of acute suppurative otitis media and acute exacerbation of chronic suppurative otitis media, a group comparison study by the envelope method was conducted using cefotiam (CTM) as the control drug (2 g twice daily). The results obtained are summarized as follows. 1.

[Surgery of malignant parotid tumors].

Surgical treatment of malignant parotid tumors was described from the viewpoints of radical cure and postoperative function. The function of the parotid gland is originally the secretion of saliva, but this is generally compensated for by the remaining major and minor salivary glands. Therefore, postoperative dysfunction involves possible facial palsy, deformity of the face and Frey's syndrome due to extirpated gland parenchyma and surrounding tissues.

Relationship between idiopathic peripheral facial paralysis and climate.

We attempted to analyse a relationship between idiopathic peripheral facial paralysis and climate. One hundred and thirty-seven patients, 76 female and 61 male, were studied. The occurrence was not correlated with the mean temperature, mean humidity or mean atmospheric pressure.

Surgical techniques of the parotid tumor.

101 cases with parotid tumors, including fourteen recurrent ones, were operated from 1976 to 1986. Surgical techniques of the recurrent cases were more complicated and difficult and often required plastic and reconstructive procedures for the skin, tissue and nerve defects. From the experiences mainly of the recurrent tumors, it was concluded that uniformly applied superficial or total parotidectomy was not always necessary but modified parotidectomy resecting sufficient and adequate tissues around the tumor should be planned individually from the prudent preoperative examinations.

[Left ventricular isovolumic relaxation time estimated by the aortic root echocardiogram].

Dual echocardiogram was recorded simultaneously with phonocardiogram (PCG) to analyze the isovolumic relaxation time (IRT) of the left ventricle (LV) in 85 patients with various heart diseases and in 23 normal subjects. The measurements used were time intervals from the onset of the aortic component of the second heart sound (IIA) to the onset of the posterior deflection of the posterior aortic wall in the aortic root echocardiogram (X) (IIA-X interval), and to the onset of the most rapid opening motion of the anterior mitral leaflet (D') (IIA-D' interval) during early diastole. 1.

Nasal resistance measured by anterior rhinomanometry.

The technique and principle of the active anterior rhinomanometry were justified by human examination and model experiment. The resistance values obtained from anterior method did not always agree with those from posterior one. Causes of the disagreement were considered to be distortion of the nostrils, air leakage from the apparatus and resistive component in the nasopharynx.

Postural deviation evoked by caloric stimulation during upright standing in man.

To understand a disequilibrium of the peripheral vestibular disorders, we tried to analyze the body sway evoked by unilateral or bilateral caloric stimulation with warm and cold water systematically. As for postural deviation, the results of our study are summarized as follows. Unilateral warm stimulation evokes heterolateral and anterior postural deviation.

Dynamics of mast cell degranulation in human allergic nasal epithelium after provocation with allergen.

The histamine content in the nasal epithelial layer of twenty-five patients with nasal allergy was measured before, 10 min after and 1 hr after nasal provocation with allergen. A decrease in histamine content was observed 10 min after provocation compared to the values obtained before provocation (P less than 0.05).
