[Assessment of workplace pollution with furadan during centalized treatment of sugar-beet seeds and recommended protective means]. / Otsenka zagriazneniia rabochikh mest furadanom pri tsentralizovannom protravlivanii semian sakharnoi svekly i rekomenduemye sredstva zashchity.

Having evaluated work conditions in sugar-beet seeds treatment with furadan, the authors justified use of an individual protective means for the workers. The recommendations are coveralls of nonwoven materials like Tyvek F, C that are resistant against concentrated and working solutions of furadan. To protect respiratory organs against furadan vapors and aerosols, one should use respirator of sorption filter half mask.

[Quantitative evaluation of ultrasonic images in differential diagnosis of bulky intraocular formations]. / Kolichestvennaia otsenka ul'trazvukovykh izobrazhenii v differentsisal'noi diagnostike ob''emnykh vnutriglaznykh obrazovanii.

A method for evaluating ultrasonic gray-scale images by plotting amplitude histograms is proposed. From amplitude histogram analysis, echogenicity and homogeneity indexes of the examined tissues were estimated. A total of 213 images of bulky intraocular formations in 58 patients were analyzed by this method. Confidence intervals of the image echogenecity and homogeneity of choroidal melanomas did not overlap the confidence intervals of the above indexes of images of pseudotumorous intraocular formations. This permits using the homogeneity and echogenicity indexes as a test for differential diagnosis of bulky intraocular formations.
