Known and newer manifestations by mycoplasma pneumoniae in adults.

Although M. pneumoniae is a well recognised respiratory pathogen both in children and in young adults, its infections have shown recently some pathomorphism and may also involve other organ systems. The paper reviews the various clinical syndromes in adults by M. pneumoniae, with particular emphasis on those more unusual and nevertheless seen by us. In this connection the possibility of pleural effusions (with a well defined cytology) associated or not with typical Mycoplasma pneumoniae and of chronic bronchopneumonias eventually evolving even in pulmonary fibrosis is stressed. Moreover, the development of M. pneumoniae respiratory infections during the course or hematological malignancies and their characteristics are described in some detail because of the relative rarity of this kind of infections in the above patients. Finally, some less frequently reported manifestations of M. pneumoniae infections, as hemolytic anemia, hepatitis and others are described and discussed.

'Cleavage fields': hypothesis on early embryonic development.

The hypothesis is put forward that events of the early embryonic development can be interpreted on the basis of a radial distribution of cytoplasmic components, i.e. of a 'cleavage field', progressively established during the growth of the oocyte. The orientations of the cleavage spindles and the corresponding furrows' positions are assumed to be correlated to the field's temporal evolution which, in turn, is determined by flows of cytoplasmic components originated by the changes in the membrane shape. From this viewpoint, a simple explanation of egg regulation is proposed, and the particular case of the sea urchin embryo is briefly discussed.
