The ocular fundi of 20 patients were examined before and after pneumoencephalography. In four of these, fresh venous retinal haemorrhages were seen, and a further patient had developed an exudate. Possible reasons for a rise in retinal venous pressure include bodily inverting the patient, compression of the thorax, the use of positive pressure respiration, and the air injection itself. It may be advisable to take steps to limit the effects of such possible causative factors. 相似文献

Reactogenic properties and survival of the smallpox vaccine virus in the organism of the vaccinated rabbits were studied for the purpose of experimental substantiation of the subcutaneous-jet method of smallpox vaccination; serological shifts were determined, and also the intensity of the immunity created to the intracerebral and intranasal infection with the pathogenic strain of the causative agent was assessed. The results of experiment were confirmed in revaccination of humans pointing to weak reactogenic properties and high immunological efficacy of the subcutaneous-jet method of smallpox vaccination. 相似文献

The disinfecting effect of decametoxin, antibiotics, such as bensylpenicillin, streptomycin, monomycin and their combinations was studied on surgical threads of various thickness previously infected with Staph. aureus, Pr. vulgaris, Bac. anthracis, E. coli, Ps. aeruginosa and Bac. subtilis. It was shown that disinfection of the surgical silk with 0.1% solution of decametoxin for 15 minutes followed by its treatment with an antibiotic solution for 105 minutes provided absolute sterility. Treatment of the surgical silk with decametoxin and antibiotic combinations alone did not provide absolute destruction of the above test-microbes. It was found that treatment of the silk with 0.1% decametoxin solution for 24 hours did not decrease its strength. 相似文献
