[Self cleaning of natural waters].

The planting of the waters left the question open as to whether the necessary expenditure of work is really worthwhile and should be encouraged. The investigations reported here with higher and particularly emersed plants, show what an astonishing influence the higher plants exert on organic and inorganic matter, on pH regulation, destruction of pathogenic bacteria, worms' eggs, and viruses, and also how they influence the waters and waste waters.

On the evocability of a positive oestrogen feedback action on LH secretion in transsexual men and women.

In transsexual men with homosexual behaviour and intact testicular function, as well as in homosexual men with normal gender identity, following a negative oestrogen feedback effect a delayed positive oestrogen feedback action on LH secretion was evoked. By contrast, in transsexual men with hypo- or asexuality and intact testes or hypergonadotrophic hypo- or agonadism, as well as in heterosexual men with normal gender identity, a negative oestrogen feedback effect was not followed by a positive feedback action on LH release. In transsexual women with homosexual behaviour and oligo- and/or hypomenorrhoea, only a weak or at best moderate positive oestrogen feedback action on LH release was evocable, similarly as in castrated and oestrogen-primed heterosexual men. By contrast, in a transsexual woman with bisexual behaviour and eumenorrhoea, a strong positive oestrogen feedback action on LH secretion was evocable, as well as in heterosexual women with normal gender identity.

[Critical remarks on the concept of "osteopathia antiepileptica"].

A study of the available specialized literature shows that it is not yet possible to provide clear evidence for a direct causal relationship between anticonvulsive medication and skeletal demineralization caused by it. Therefore, it is strongly recommended that such disorders of ossification be not overhastily described by terms declaring the changes in bones to be complications caused by drugs used in antiepileptic therapy. Relationships between the tetanic and epileptic syndrome are discussed by reference to the author's own clinical experience and to the latest results obtained in the field of calcium and vitamin D metabolism, with special consideration being given to a corresponding intermediate group that is characterized by the presence of components of both of the syndromes referred to above.
