Enzyme activity of PGM1 in erythrocytes

The enzyme activity of phosphoglucomutase (PGM) has been investigated in red cell haemolysates from 142 individuals and compared to the sub-type as determined by isoelectric focusing. The 10 phenotypes showed significant differences in PGM-activity which indicates that there is a correlation between the level of activity and the isolelectric point of homozygotes. No indication of silent alleles or alleles with reduced activity was found in this collective.

Perceived helpfulness and use of professional services by abused women

Many abused women use professional and community services and begin to talk to professionals about the abuse they have endured. This article presents and discusses results of a study of 270 abused women who used the services of professionals and service agencies. The article presents information on the frequency of contact and the perceived helpfulness of different professions. Also presented are the types of responses which were considered to be useful and ineffective. This study revealed that the most frequently contacted professions were not necessarily perceived to be the most helpful. Further, certain responses of the service providers were more frequently reported to have value.     

Explanation of nonspecific serologic reactions in decomposed bone tissue

Bone fragments were stored in water for 2 years at room temperature and investigated serologically using the following methods: Absorption-elution, extraction of blood group substances and immunohistochemistry (PAP). All 3 methods gave essentially specific results for fresh bone tissue but with putrid bone tissue unspecific reactions were found predominantly with the absorption-elution and PAP techniques. In contrast, more specific reactions were obtained from the extracts although they were much weaker. From this it can be concluded that pure physical binding plays a substantial role in the unspecific reaction between antibodies and bone material. It is suggested that the relevant physical properties are altered by putrification.
