We present the case of a 7-month-old girl with Gaucher disease who required anesthetic care during laryngoscopy, bronchoscopy, and central line placement. Gaucher disease is a familial disorder of lipid catabolism with autosomal recessive inheritance. Due to the defective function of the enzyme glucosylceramide beta-glucosidase, glycosphingolipids accumulate, leading to end-organ dysfunction. Three clinical variants of the disease, which differ in age of onset, degree of central nervous system (CNS) involvement, and frequency in the population, have been described. Of concern to the anesthesiologist is the occurrence of significant CNS dysfunction in types II and III, with seizures, gastroesophageal reflux, and chronic aspiration. Bulbar involvement and infiltration of the upper airway with glycolipids may lead to upper airway obstruction. Additionally, hepatosplenomegaly, present in all three variants, may lead to hypersplenism with thrombocytopenia and anemia. Preoperative identification of the associated end-organ dysfunction will allow the safe provision of anesthetic care for these children.

Results of the electron-microscopic investigation of root apices of Arabidopsis thaliana 3-, 5- and 7-days-old seedlings grown in the stationary conditions and under clinorotation are presented. It was shown the similarity in the root apex cell ultrastructure in control and under clinorotation. At the same time there were some differences in the ultrastructure of statocytes and the distal elongation zone under clinorotation. For the first time the sensitivity of ER-bodies, which are derivatives of GER and contain beta-glucosidase, to the influence of simulated microgravity was demonstrated by increased quantity and area of ER-bodies at the cell section as well as by higher variability of their form under clinorotation. A degree of these changes correlated with the duration of clinorotation. On the basis of experimental data a protective role of ER-bodies in adaptation of plants to microgravity is supposed.
