[The analysis of dosage inaccuracy and its minimization modes].

The article deals with the analysis of factors impacting dosage inaccuracy and input of this inaccuracy into total inaccuracy of analysis. The total dosage inaccuracy includes both the value of inaccuracy mentioned in the technical passport of dosage device and inaccuracy values occurring at all stages of dosage during implementation of technique. The characteristics of dosage devices and their merits and shortcomings are taken into account.

[Our method of functional rheography of eye].

The technology of rheoophthalmogram obtaining and processing is modified by creating an automated rheographic complex (ARGC). The test for assessing the function of ocular vessels includes recording of the background rheoophthalmogram, local 10-min hypothermal exposure (+10 +/- 2 degrees C), and repeated recording of rheoophthalmogram 10 and 20 min after hypothermal exposure. The test helps determine the type of neurovascular reaction and the index of ocular vessel elasticity.

[The toxicological hygienic evaluation of the manufacture of epoxy resins based on complex glycidyl ethers].

The workers engaged in the processing of the UP-671, UP-671D, UP-677, UP-680 and UP-682 epoxide resins are influenced by both initial and intermediate industrial products, as well as the resins' volatile components in MAC threshold concentrations. The workers engaged in major professions displayed upper respiratory allergic diseases, contact and allergic dermatitis, sensibilization to epichlorhydrine, staphylococci and kidney allergen. Euthyroid goiter was diagnosed in most workers, along with thriiodothyronine decrease in blood serum and a higher rate of chromosomal aberrations in lymphocytes.
