[Thrombocyte storage in plasma. Preparation and storage of thrombocyte concentrates in polyvinyl chloride PL 146 standard bags].

Platelet concentrates (PC) were prepared from CPD-blood using PL-146 triple bag system (Fenwal). They were stored in 60 ml plasma at room temperature for 72 h with gentle agitation by side-over-side rotation with 2 rpm. PC contained on average more than 0.55.10(11) platelets form 450 ml blood. There were significant correlations between pH-values and platelet number as well as percentage of disc-shaped platelets. pH-values, number of platelets and morphology were well maintained in all PC, but 4 of 18 had pH-values below 6.0 after 72 h. This means that 95% of the stored PC had sufficient quality after 48 h and only 78% had it after 72 h.

[Evaluation of occupational risk for workers producing polyvinyl chloride resin pipes, profiles and fixtures].

Studies are performed on work and hygienic conditions in the production of pipes, profiles and fittings from polyvinylchloride resin, in relation to the toxic factor. Concentrations above TLV are established for vinylchloride, vinylchloride resin dust, phthalates and lead aerosols. Complex clinico-laboratory examinations are carried out on 133 workers, as special attention is paid to the nervous system, liver function, cardio-vascular system and the skeleton system. In 15 workers are established data for toxic effect of vinylchloride, and in other 5 workers - toxic pneumosclerosis, which is a result both from vinylchloride and vinylchloride resin dust. Hygienic and medico-preventive measures are developed.
