ジャーナル フリーLocalization of motoneurons for each muscle innervated by the nucleus ambiguus (AM) was studied by means of the horseradish peroxidase (HRP) method' in 201 cats. Also, the exact extent of AM in the rostrocaudal direction was determined using the same technique. HRP labeled neurons were observed ipsilaterally for all the muscles except for the esophageal (E) muscle. The motoneurons of the stylopharyngeus (STP) were recognized in the retrofacial nucleus (RF). The motoneurons of the cephalopharyngeal (CeP), the hyopharyngeal (HP), the thyropharyngeal (TP), the cricopharyngeal (CP), E and the cricothyroid (CT) muscles were found in RF and the rostral part of AM. For the levator veli palatini (LVP) muscle, the motoneurons were observed in the rostral part of AM. The motoneurons of the posterior cricoarytenoid (PCA), thyroarytenoid (TA), lateral cricoarytenoid (LCA) and interarytenoid (IA) muscles were found in the caudal part of AM.
Beginning at the level immediately caudal to the superior olivary nucleus, the cell column of AM extended caudally to the level of the caudal end of the inferior olivary nucleus. The length of the cell column was 5.5-6.0 mm in adult cats. The cell column were divided into three sections cytoarchitecturally: the rostral one sixth which was loose, the next two sixths which was compact and the caudal half which was loose in formation. The rostral loose formation contained most of the cells innervating STP and a part of the cells innervating CeP and HP. The compact formation consisted of two portions: the large cell group which occupied large part of AM and was located ventrolaterally and the small compact cell group which was located dorsomedially. The former innervated E and CT, whereas the latter innervated Cep, HP and LVP. However, the motoneurons for TP and CP were supplied from both of them. The caudal loose formation was connected to those groups of the compact formation. It contained the cells innervating of PCA, TA, LCA and IA.
Following HRP injection into the nodose ganglion, the recurrent laryngeal nerve and the external branch of the accessory nerve, the junction between the caudal end of the cells column of AM and the motoneurons of the accessory nerve was clearly differentiated. There was no connection between these two groups of neurons.抄録全体を表示PDF形式でダウンロード (35589K) -

ジャーナル フリーForty-nine patients undergoing nasal and paranasal surgeries were anesthetized with the use of neuroleptics or tranquilizers, analgetics, nitrous oxide and oxygen.
Seventeen patients were anesthetized with a combination of droperidol and fentanyl, i. e., the so-called original neuroleptanesthesia. Twelve patients were anesthetized with a combination of diazepam and pentazocine, eleven patients droperidol and pentazocine. These combinations are referred to as the so-called modified neuroleptanesthesia. Nine patients were anesthetized with a combination of diazepam and ketamine which was given with a micro-mini drip administration technique. The results were summarized as follows:
1) Neither remarkable respiratory depression nor ventilatory difficulty was found.
2) Five×10-6% of epinephrine was locally injected for the purpose of hemostasis. A mean dose of 0.2ml/kg of its solution proved to be safe for use. Blood pressure remained stable during the operation in the majority of cases.
3) Renal, adrenal and liver functions were in good conditions without any remarkable side reactions.
4) The amount of bleeding was significantly greater during operation when using neuroleptanesthesia than traditional local anesthesia.
5) Patients were rapidly recovered from anesthesia and were tranquil during postoperative period.
These results suggest that neuroleptanesthesia is one of the most promissing methods of anesthesia for nasal and paranasal surgeries.抄録全体を表示PDF形式でダウンロード (2054K) -

ジャーナル フリーA comparative investigation of the histological structure of the vocal fold mucosa was conducted with 11 different mammalian species. The results are summarized as follows:
(1) The histological structure of the lamina propria of the vocal fold mucosa significantly varies between the mammalia investigated.
(2) The lamina propria can be divided into a certain number of layers according chiefly to the distribution and density of fibrous components in all the mammalia studied except for one. Men, horses, monkeys, guinea pigs, oxen and rats have 3 layers, while dogs, pigs, rabbits and sheep have 2 layers. Only cats present a single layer.
(3) Structures equivalent to the human anterior and posterior maculae flavae are found in the following 6 animals: dogs, monkeys, cats, guinea pigs, oxen and rats. The elastic fibers in the lamina propria are continuation of these flavae. In the other 4 animals, i. e. horses, pigs, rabbits and sheep, no such structures as maculae flavae are observed.
(4) All the species investigated have an anterior commissure tendon which consists of collagenous fibers. Most collagenous fibers in the lamina propria run between this tendon and the perichondrium of the vocal process of the arytenoid cartilage.
(5) It should be emphasized that reasonable interpretation of data obtained from animal experiments on phonation calls for a thorough understanding of the differences in vocal fold7structure between men and the animals employed.抄録全体を表示PDF形式でダウンロード (49817K)
