Jiro Hozawa, Shigeki Kamata, Takashi Ishida and Noriko Kimura (Hirosaki University) The labyrinths of guinea pigs sensitized by horseradish peroxidase (HRP) were investigated by electronmicroscopy after challenging this antigen through the foram. stylomastoideum. Horizontal nystagmus toward the contralateral side was observed about fifteen minutes after challenging. The animals sacrified in thi...

Broth-culture filtrates of Campylobacter pylori induced non-lethal cytopathic effects in vitro in 7 of 9 mammalian cell lines tested. Transmission electronmicroscopy revealed that the response consisted of intracellular vacuolisation. Intestine 407 cells were among the most responsive and were used for routine assay. About 55% of isolates of C. pylori tested, originating from four geographic re...

Culture samples of Neisseria gonorrhoeae and Escherichia coli were studied by transmission and electron microscopy to evaluate the effect of different preparation procedures on the pilation of these organisms. Unfixed as well as fixed bacteria showed only few, long, filamentous appendages when investigated in ultrathin sections, negatively stained specimens, or critical-point dried preparations...

It has been shown (Still and Boult. 1956) that when teased preparations of the endocardium in congenital endocardial fibroelastosis are studied by electronmicroscopy the superficial zones are largely composed of a material bearing little resemblance to collagen or elastic tissue, as the histological appearances suggest, but having the morphological characters of fibrin. We proposed therefore th...

phenols are toxic organic compounds and which badly affects the flora and fauna of thebiosphere because phenols are persistent pollutant found in wastewater from many industries. in presentresearch article the photocatalytic removal of o-nitro phenol by synthesized magnetic nanoadsorbents(mna) carried out under photocatalytic reactor. the mna were synthesized by co-precipitation methodrequired ...

Background: Chronic intermittent hypoxia is the primary pathophsiological feature of obstructive sleep apnea/ hypopnea syndrome. The characteristics of CIH can be imitated by animal experiment models thus to study CIH related systemic organ injuries, including respiratory systems. Methods: Sixteen male SD rats were randomly divided into two groups: CIH group (n = 8) and control group (n = 8). T...

to investigate the effect of tempering treatment on mechanical properties and the microstructure ofdin 1.4021 martensitic stainless steel, austenite treatment was conducted for the samples at 1000ºc temperature for 60 min and then the samples were oil quenched. later, tempering treatments wereperformed for the samples at 500 ºc and 700 ºc temperatures for 2 and 5 h, respectively; then quenching...

the dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. cu and ni unites nanocatalyst powders sithcomposition of caned], and nife204 were synthesized by a sol-gel auto catalnic combustion process. themolar ratio between metal ions and urea was 11.2. the sob gel process was done at 8...
