[Experience with clindamycin in stomatologic diseases].

In 114 patients suffering from dental inflammatory diseases (periostitis, gingivitis, sinusitis, periodontitis etc.) and in 41 cases of dental surgical procedures (implantation, dentoalveolar surgery etc.) 3 x 300 mg/day clindamycin was applied during 7 days in the framework of GCP phases IV. In 150 cases (97%) the product proved to be effective and only in 2 cases a mild side effect was observed. On the base of the results clindamycin can be advised for the treatment of stomatological diseases.

[Cholinergic innervation of the oviduct in rabbits].

Distribution of cholinergic nerves in the oviduct wall in rabbits was investigated by a neurohistochemical method after El Badawi and Schenk (1967). Higher density of cholinergic nerve fibres was confirmed to occur mainly in the isthmic part, but in contrast with literary data it was also found in the ampullar part of oviducts. In the basal parts of oviduct mucosa there were only few cholinergic nerve fibres unlike their density in woman's oviduct. A major part of cholinergic nerves are concentrated in a thick muscular tissue; this is probable to be related with its influence on oviduct motility. In the course of pregnancy, progesterone reduces the number of cholinergic nerves in rabbit oviducts, the number is largely reduced in all layers. These results are considered as preliminary with respect to the number of test rabbits; they indicate that the rabbit oviduct is not any ideal model to study the development of cholinergic innervation in dependence on oestrous cycle phase and pregnancy duration and that they should not be applied to changes in the functional neuromorphology of tuba uterina in woman.

[Changes in cholinergic innervation in the human oviduct during pregnancy].

Using a neurohistochemical method for visualization of ACHE positive nerves according to El Badawi and Schenk (5), the authors investigated the distribution of the cholinergic innervation in the oviducts of pregnant women. The cholinergic nerve fibres were present in the oviducts during all trimesters of pregnancy. ACHE positivity of nerve structures in the musculature did not display substantial changes. On the other hand, the authors observed in the mucosa of the oviduct marked changes. In the first trimester they found few cholinergic fibres, in the second and third trimester the number of cholinergic nerve fibres increases. The findings provide evidence that the cholinergic innervation of the mucosa of the oviduct is oestrogen dependent. It will be necessary to elucidate the problem of increasing ACHE positivity of nerve structures during pregnancy by further observations.

[Adrenergic and cholinergic innervation of the kidneys in several mammals].

In dogs and some other mammals, the major neuronal sources for plexus renalis, distribution, architectonics and topographic interrelations of intrarenal neuronal plexus were studied. Adrenergic nerve fibres were revealed by the luminiscent histochemical technique; cholinergic--by the cytochemical method for acetylcholinesterase identification. Peculiar patterns of the intrarenal adrenergic and cholinergic neuronal plexus around the preglomerular arterial bed (main periarterial and adventitial plexus), innervation of efferent arterrioles and vasa recta are described. The system of fine varicous fibres forming neuronal plexus in the marginal zones of the connective tissue and at the cortico-medullar border, that of cortical tubes, venous, pelvic and fibrous capsule innervation of the organ are considered. Some species differences are discovered. The data obtained are compared with those from literature and discussed in terms of functional neuromorphology.

Relationship of blood vessels to small intensely fluorescent cells in the autonomic ganglion.

In our experiments we observed the relationship of the blood vessels to the small, intensely fluorescent cells (SIF cells) in the lower mesenteric ganglion of the cat. We injected the solution of Evan's blue into the ganglia and processed them with the fluorescent histochemical method by Falck and Hillarp. We observed that the SIF cells are placed in the ganglia closely to the blood vessels or closely round them. When observing lager groups of SIF cells placed at the edge of the ganglia a dense network of the blood vessels was observed among these cells.
