Inquire into the mechanism of inner ear pathological physiology in autoimmune sensorineural hearing loss (ASHL). With the auditory electric-physiological techniques and enzyme-histochemical method, the change of inner ear hearing function and enzyme activity were observed. These animals, which threshold of auditory nerve compound active potential (CAP) and(More)
OBJECTIVE Research into the technique and signification of reducing remnant tumor with utilizing endoscopic technique during removal of acoustic neuroma. METHOD 15 patients proceeded the removal of acoustic tumor through retrosigmoid approach (as routine retrosigmoid-approach operation group, RRSO-G), 11 patients utilized endoscope for inspecting and(More)
Twenty one cases of kaposi's sarcoma (KS) with manifestation in the field of otolaryngology are reported. The incidence of KS is increasing following epidemic of AIDS all over the world. Epistaxis, nasal obstruction, sore-throat, dry of foreign body filling in throat and nodal mass are most frequent manifestation. The relationship of KS with HIV, it's(More)
7 Conclusions EOS is a storage manager that has been prototyped at AT&T Bell Laboratories as a vehicle for research into distributed storage architectures for database systems and specially those that integrate programming languages and databases. EOS is the storage manager of ODE 1], an object oriented database management system also being developed at(More)
It was investigated that the clinical unspecialized immunological factors and special immune reaction against to inner ear antigens relate with the cause of Meniere's disease. Every of the relative immune tests and special humoral and cellular immune reaction tests were proceeded in the breaking out and intermittent period of Meniere's disease patients, and(More)
This paper describes the client-server software architecture of the EOS storage manager and the concurrency control and recovery mechanisms it employs. Unlike most client-server storage systems that use the standard two-phase locking protocol, EOS o ers a semi-optimistic locking scheme based on a multigranularity two-version two-phase locking protocol.(More)
~-Amino-6-mercapto-9fl-D-ribofuranosylpurine (thioguanosine) has been used orally and intravenously in the t reatment of 82 patients with leukemias and disseminated tumors. The oral dose of thioguanosine required to produce toxic or therapeutic responses was less than half the oral dose of thioguanine necessary to produce comparable results calculated on a(More)
OBJECTIVE To research the therapy effect of perennial allergic rhinitis (PAR) with anterior-ethmoid neurotomy, and to observe the pathological changes of SP nerve fibres. METHOD In 46 cases (neurotomy group, NG) of PAR anterior-ethmoid neurotomy were performed, the surgery effect was evaluated according to the Chinese Hai Kou allergic rhinitis diagnosis(More)
OBJECTIVES To inquire into whether the different inner ear tissue antigens could cause different kind of hearing loss, and to find out the disorder positions of auditory system. METHODS The basilar membrane (BM), spiral ligament (SL), and spiral ganglion (SG) of guinea pigs were removed for making antigens, respectively. Then, we used these antigens to(More)
