[Evaluating guidelines for "selection and training of staff for odor analysis"--a 7-year longitudinal study].

During a 7 years longitudinal study on a representative group the guideline "selection and schooling of personal for odour analysis" was reexamined. It could be shown that the selection in two steps is well suited to recognize anosmia and hyposmia, respectively and that normal osmia is well to be characterized by smell scores of 30-42. A statistical significant training effect could be shown with the qualitative test for training of the odour memory as well as the articulation in describing of smell impressions. The result of the rank order test demonstrate the practicable subdivision of the odour intensity into 5 degrees.

[Gas chromatography studies of exhaust air from an animal body waste salvage industry].

The proceedings of animal body waste salvage plants are-as you know-connected with intense smell importunities of the immediate environment. Suited desodorization plants are required to limit this problem of the environmental hygiene. The presupposition for a high effectiveness of these plants is to know the qualitative composition of the exhaust air, the analysis of which is the subject of the article in hand.

[Atrial arrhythmias after surgical repair of an atrial septal defect (secundum-type). Six years follow-up in adults (author's transl)].

Atrial arrhythmias before and after repair of an atrial septal defect (secundum-type) were analyzed in 100 patients. The mean postoperative follow-up was 5.8 years, the mean age at the last check-up was 33.4 years. Preoperatively, 10 patients showed atrial arrhythmias (6 pts atrial flutter or fibrillation [AF], 3 pts sinus node [SN] dysfunction, 1 pt atrial tachycardia). About 6 years after operation, 29 patients showed atrial arrhythmias (16 pts AF, 10 pts SN dysfunction, 3 pts atrial tachycardias). The 26 patients with AF and SN dysfunction were 10 years older and had a 3 years longer follow-up period postoperatively than those with sinus rhythm. In addition, they had a higher pulmonary artery pressure preoperatively. Especially the occurrence of AF after operation was strongly related to the age and the pulmonary artery pressure. All other factors had no significance. The data show that closure of an atrial septal defect cannot prevent the occurrence of AF in the following period. In addition, SN dysfunction is found postoperatively in a significant number of patients probably due to the intraoperative injury to the sinus node. However, it cannot be excluded that the unfavorable results may in part be due to the selection of the patients.

The transfer of J blood-group activity from J-containing bovine serum to J-negative erythrocytes.

The J blood-group activity of bovine serum is contained both in a lipid and in a nonlipid fraction. This is also true for calf serum. It demonstrated that the J determinant is transferred from a serum protein onto the erythrocyte membrane by incubation in vitro. Even though the donor of J activity is a lipid-free serum protein (probably a glycoprotein), the transferred J activity is detectable only in the lipid fraction of erythrocytes. Thus, the J determinant (probably a carbohydrate unit) must have been detached from a serum glycoprotein and transferred to a lipidic receptor (probably a glycosphingolipid) at the erythrocyte membrane. It is suggested than an enzyme system located in or at the erythrocyte membrane is responsible for the transfer of J substance. The transfer of J substance is inhibited by a polar lipid present in bovine serum.
