[Outline of a sociological approach to the psychopathology of women].

It will only be possible to understand and explain the facts peculiar to the psychopathology of women if they are related to the specific characteristics of the positions occupied by women in various domains of society. Women's place therein is discriminated against or deemed inferior in several respects, whether in the family, the profession, the periods of education or social participation. Their image in society as well as certain cultural values and norms are evidence of and confirm this situation. It is clear that identical factors are behind the minor deviations in the form of limited maladjustment, the cases of more profound maladjustment and the psychopathological facts noted. The processes of adjustment of the latter as well as the psychiatric treatment vary greatly according to the social class to which the patient belongs. The specific traits of the psychopathology of woman incorporate and express at the same time her social status, her image and the characteristics defined and attributed to her by culture.

[Light and electron microscopic studies of slowly adapting abdominal stretch receptors of the American river crayfish Orconectes limosus (RAF)].

The slowly adapting abdominal stretch receptors of Orconectes limosus (RAF) have been investigated morphologically; 1. Despite their variety of size and shape all slowly adapting receptor neurons show common characteristic features which in addition distinguish them clearly from the fast adapting receptor neuron type SN2. The slightly globular cells have always several dendrites (often 4-6). They originate apical or lateral to the neuron, are oriented mainly longitudinal to the muscle fibres and are brodly ramified. The fine dendrites form a 3-dimensional fibrilar network. 2. The structure and distribution of the connective tissue in the "intertendon" of the muscle receptor organ correspond to the dendrite ramification; In this area, some muscle fibres end direktly at tendon-like connective tissue structures, but a number of different fibres run uninerruptedly through the whole muscular fascicle. 3. The perikaryon of every sensory neuron shows 2 "cytoplasm types" which are clearly distinguishable one against the other. A characteristic feature of the granular-lamellar neuroplasm that closely surrounds the nucleus are many flat vesicles of the granular endoplasmatic reticulum, accumulations of free ribosomes, numerous mitochondria and Golgi fields. The fibril-rich neuroplasm on the contrary contains only few mitochondria, but very many neurofilaments, here and there also neurotubuli. It projects directly into the dendrites and neuritek. Cell bodies, axon and dendrites are surrounded alternatingly by sheath cells and connective tissue of collagenous nature. The innermost layer of the coat cells borders directly on the neuron membrane. Finer dendrites are enclosed by nothing more but a thin layer of sheath cell plasm and intercellular substance. The dendrite terminals are either stored directly in connective tissue ground substance or border immediately on the sarcoplasm. 5. The axo-dendritic or axo-somatic synapses, respectively, contain numerous ellipsoidal (250-350 X 400-500 A), but also many spherical, vesicles. Some vesicles have a slightly larger diameter (700-900 A) and contain an electron-dense core. The synaptic gap measures 150 to 200 A. The neuromuscular (supposedly excitatory) synapses are filled much lighter with vesicles as compared with those just mentioned, which show a relatively unique form and size (nearly all spherical, phi 400-500 A). There are less vesicles with an electron-dense centre. On the average, the synaptic gap is broader (200-250 A) and the contact zone is larger. Apart from these, terminals could be observed in the dendritic ramification area, too, resembling the axo-dendritic and axo-somatic ones, respectively. 6. Finer dendrite branches contain vesicles differing slightly from those mentioned above as far as shape and size are concerned. Their diameters vary between 500 and 1 000 A. "Dense bodies" could be observed sporadically in these vesicles.

[Value of colpocystography for the diagnosis of incontinence].

Striving to improve diagnosis of the functional urinary incontinence in female patients, we carried out colpocystographic examinations in 78 women. With inconspicuous X--ray photos (22) the rest of the diagnostic parameters--with the exception of one--indicate mostly an irritable bladder (4) or at the very least a notable component of an irritable bladder (56). With radiographic findings suggesting stress incontinence (56) a complete (19) or least a partial (27) coincidence with the clinical findings, was likewise more often than divergent findings (only 10 prevalent irritable bladders). Methodology of examination and analysis are explained. The essential advantage of the colpocystographic method over the traditional urethrocystographic methods is according to our hitherto existing experiences, that we can additionally recognize adhesions between urethra, bladder and vagina, which we have to operate. These adhesions can involve both a stress incontinence and an irritable bladder. Consequently this method is suitable for the complex diagnosis of the functional urinary incontinence in female patients.
