摘要:

Effects of plasma fraction I (‘fibrinogen’) on post-tonsillectomy bleeding were compared with surgical treatment and infusions of saline on randomized groups of adult patients. Surgical revision of the bleeding site arrested bleeding in every patient (13 cases), whereas infusion of 2 g of plasma fraction 1 effectively controlled bleeding in 32 out of 42 patients without any additional surgical treatment. In all of the patients receiving plasma fraction 1 without permanent arrest of bleeding the additional surgical revision was successful. Infusion of saline alone failed to influence post-tonsillectomy bleeding (6 patients). The difference in the effects of plasma fraction I and saline is statistically significant. Hemostatic and clinical evaluation of the patients with post-tonsillectomy bleeding did not demonstrate any apparent causes which would explain a bleeding tendency in comparison with a control group undergoing tonsillectomy without abnormal hemorrhage. In conclusion, infusion of 2 g of plasma fraction I is a partially effective treatment of post-tonsillectomy hemorrhage, but the mechanisms of action of this treatment remain unkn

摘要:

The epithelium lining of trachea and lung in rats and mice after administration of 5% dextran iron solution, ferritin and charcoal particles were investigated with the aid of electron microscopy. An enzyme for fluid transport, adenosine triphosphatase, has also been studied by electron microscopy. The microvilli in ciliated cells of the trachea increased in their number after administration of foreign substances, and many micropinoeytosis vesicles take up the ferritin into the ciliated cells but no dextran iron particles were found within the ciliated cell. A large amount of charcoal particles were observed within the ciliated cells with no cilia in cases of inspiration for long hours. All tracers used in this study were found within (he alveolar epithelial cells, so-called dust cells and capillary endothelial cells in lung. ATPase activity could be demonstrated on the surface of the microvilli and cell membrane of ciliated cells but not on cilia.

摘要:

This report pertains to a case of ceruminoma of the middle ear, in which the treatment and microscopical picture of the tumour are accounted for. To judge from the relevant literature, there seems to be some uncertainty as to the nature of ceruminomata. In some instances this uncertainty is the result of inadequate histopathological examination, but also of the tendency of the tumour to relapse and even metastasize, which contrasts with the seemingly benign histological picture. The number of reported cases of ceruminoma is not great. Thus, in order to clarify the pathogenesis of ceruminal tumours, additional reports based on thorough clinicopathological examinations, would seem to serve a useful purpose.

摘要:

The pneumatisation of the temporal bone after mastoidectoniy in early childhood was checked by X-ray examination in 79 cases. The younger the children have been at the time of the operation, the higher was the percentage of a new good pneumatisation of the temporal bone in the later age. A characteristic finding was a difference in the size of the cells, even if the pneumatisation has developed good again. The statistic evaluation showed, that the application of antibiotics had no significant influence on pneumatisation. In addition there was no connection between finding’s at the time of operation, duration of healing, results of the bacteriological examination and pneumatisation. On the contrary years later all cases with recurrent mastoiditis developed a sclerotic mastoid. The swabs of the auditory cannal showed much more staphylococci, than out of the mastoid cavity. In the mastoid cavity the streptococci were the most seen germs. As a result of the audiomelric examination patients with sclerotic mastoids after mastoidectoniy in childhood had a higher percentage of hearing loss, than those with a good pneumatisatio

摘要:

Temperature differences (ΔT) were recorded from the horizontal semicircular canal of the squirrel monkey during caloric stimulation. A precise, well-defined relationship was found to exist between the onset of nystagmus and temperature difference between the ampulla and crus of the horizontal canal

摘要:

Rheographic recording of circulatory variations on the forearm following caloric-vestibular stimulation in 33 tests on 25 subjects showed no significance in 10 subjects (30° water, fasting), while 5 persons (30° water, non-fasting) exhibited significance during the periods 60–70 sec and 80–90 sec after the start of the irrigation. In 10 persons (20°C water, non-fasting) there was significance 80–90 sec and 100–110 sec after the irrigation was started. In a control group of 8 out of the 25 subjects (37°C water, non-fasting) significance was found 100–110 sec after the irrigatio

摘要:

It is rare to find vestibular disorders in the course of purulent acute otitis media when simple serous labyrinthitis has been excluded as possible cause. Twelve such cases are presented, in which the symptom is interpreted as an isolated manifestation of acute, non-suppurating encephalitis. It is characterized by the sudden onset, the transitory nature and rapid change of the nystagmus, in which no regular pattern can be discerned, and by the normal sensitivity of the auditory passage to heat and the absence of signs of inner-ear hearing defects. Thrombosis, congestion as a result of damage to the vessel walls by bacterial toxins, with subsequent localized oedema, reflex mechanisms from the diseased focus, vasodilating vagus influence via the superficial petrosus major or an allergic process in the region of the central vestibular nerve pathway are all discussed as possible causes for this generally quite benign condition.
