A randomized study comparing the use of a pelvic lead shield during trans-radial interventions: Threefold decrease in radiation to the operator but double exposure to the patient.

Objectives: To determine the efficacy of a 0.5-mm lead apron across the patient's abdomen in addition to standard operator protection for the reduction of scatter radiation on operator and patient radiation exposure

Background: Cardiac angiography using the radial access compared to the femoral approach is associated with reduced complication rate and improved patient comfort but has significantly increased radiation dose. Improvements in radiation protection are needed

Methods: We randomly assigned 332 patients undergoing coronary angiography to a group with pelvic lead shielding and a group with standard protection.

[Ecology of the geohelminths of Karakul sheep in the Kyzyl Kum].

Data on the ecology of geohelminths and epizootiology of main geohelminthiases of Karakul sheep under conditions of desert-pasture biocoenoses of the Kyzyl Kum in the Bukhara and Navoi Provinces of the Uzbek SSR are given. 23 species of geohelminths belonging to 14 genera and 8 families are reported from this zone. Age and seasonal dynamics of the infection rate of Karakul sheep with geohelminths are established.
