The inability of standard therapy to provide adequate protection against poisoning by organophosphorus compounds (pesticides and nerve agents) motivated us to search for new, more effective oximes. We investigated the pharmacotoxicological properties of six experimental K-oximes (K027, K033, K048, K074, K075, and K203) in vivo. The therapeutic efficacy of K-oximes (at doses of 5 or 25 % of their LD50) combined with atropine was assessed in paraoxon-poisoned mice and compared with conventionally used oximes HI-6 and TMB-4...

INTRODUCTION: In the mid-twentieth century, the health care of women and children was inadequate in the post-war Yugoslavia, including the city of Novi Sad, due to the severe post-war reality: poverty in the devastated country, shortage of all commodities and services and especially of medical supplies, equipment and educated staff. OUT-OF-HOSPITAL MATERNITY UNIT: One of the serious problems was parturition at home and morbidity and mortality of the newborns and women. Soon after the World War II the action programme of improving the women's health was realized on the state level by establishing out-of-hospital maternity units but under the expert supervision...
