During the years 1972--1975, the author performed nitrate determinations, using the xylenol method according to E. Bohm, to verify if the standard or maximum permissible values established by the Ministry for Health of the GDR in 1972-1973 for spinach and spinach preserves for babies had been respected. The relative standard deviation of the method is +/- 5%. The values found in spinach samples of the same harvest and from the same area varied considerably (up to +/- 40% of the mean). Taken altogether, the nitrate content, especially in autumn spinach, exceeded by far the maximum permissible values for baby food as well as for general consumption in spite of contractual agreement with the farmers on the use of nitrogenous fertilizers. It is recommended to study systematically all the factors of nitrate accumulation in order to secure safe spinach products.

[The gerontopsychiatric team in the specialized department].

People 65 years and older constitute a group with high risk for psychiatric disease, and their numbers are increasing. At the same time familial networks and financial resources are weakening. In order to improve psycho-geriatric therapy, we developed teamwork within our department. In the present work we describe the psycho-geriatric ward and the special functions of team members. It seems to be important that there are enough staff members who are well trained and motivated; it should be guaranteed that members regularly meet in conferences and have regular supervision; work hours should be favorable. Team process is described as consisting of imaging a comprehensive idea of the personality and the problems of the patient; agreeing on a therapeutic proceeding and-as a result-translating into action. Finally, it focuses on the necessity for further development and research.
