[Clinical manifestations of syphilis in maxillofacial area. Part II].

The article presents a review of the literature with a description of typical manifestations in the maxillofacial area in secondary, tertiary period of syphilis and the description of photo-images of the authors' clinical observations. In the secondary period of syphilis rashes can be found both on the skin and mucous membranes. In secondary reccurent syphilis the oral cavity is affected in 56% of the cases.

[To the issue on the optimization and regulation of microclimate in the subway trains and stations].

There is presented an overview of currently existing regulatory framework governing the parameters of the microclimate in the salons of subway passenger cars and stations. Analysis of the normative documents indicated that they contain very incomplete, contradictory, often unfounded information about the parameters of microclimate parameters in salons of subway rolling stock. Also, there are no clear cut hygienically-sound requirements for the work of imposed on the rolling stock subway systems provide microclimate, including new systems for air conditioning and disinfection.

Does a concomitant exposure to lead influence unfavorably the naphthalene subchronic toxicity and toxicokinetics?

Rats were given 20 times during 40 d either naphthalene per gavage or the same and lead acetate intraperitoneally in single doses corresponding to 5% of the respective 50% lethal doses. The concomitant exposure to lead not only added some typical indicators of lead toxicity to the moderate naphthalene intoxication picture but also exaggerated some less specific indices for intoxication. However, a number of such indices testified to attenuation of naphthalene's adverse effects under the impact of lead.
