Bone structure of the temporo-mandibular joint in the individuals aged 18-25

Osteohistometric studies were performed in 15 female and 15 male cadavers aged 18-25. Condyloid process and right and left acetabulum of the temporo-mandibular joint have been studied. Density has been investigated using monitor screen linked with microscope (magnification 80x). Density in the spongy part of the condyloid process was 26.67-26.77%; in the subchondrial layer--72.13-72.72%, and in the acetabular wall 75.03-75.91%. Microscopic structure of the bones of the temporo-mandibular joint revealed no differences when compared with images of compact and cancellous bone shown in the histology textbooks. Sex and the side of the body had no influence on microscopic image and proportional bone density. Isles of chondrocytes in the trabeculae of the spongy structure of the condyloid process were found in 4 cases and isles of the condensed bone resembling the compact pattern in 7 cases.

Carcinosarcoma of the lung. Report of three cases

This article presents three cases of carcinosarcoma of the lung which is considered to be a rare neoplasm. The authors describe supposed etiology, clinical symptoms, preoperative diagnostic difficulties, surgical interventions performed, postoperative course and follow-up. The role of modern histopathological techniques like use of monoclonal antibodies reaction against keratin, vimentin and neurofilaments in differential diagnosis is emphasized. Short review of other authors reports is presented.

[Churg-Strauss syndrome: two cases histories]

Two cases of Churg-Strauss syndrome with severe polyneuropathy have been diagnosed according to clinical and histopathologic criteria. Perforation of small intestine, successfully treated with surgery, was observed in one of two cases. The resected part of gut presented specific histologic picture of Churg-Strauss syndrome.

Salbupart effect on rabbit heart and brain

In connection with the widespread use of the product Salbupart POLFA in the treatment of imminent premature labour the effect of this medicament on rabbit fetuses was studied. In all, 29 fetuses were examined, particularly with histological examination of the heart and the central nervous system. No harmful effects of the medicament on these organs was found. In the fetal central nervous system Salbupart produced more intense staining of myelin sheaths by Heidenhain's method which may suggest earlier maturation of the brain.

[A case of mitochondrial enzymopathy]

A case of mitochondrial enzymopathy, called also ophthalmoplegia plus, was observed in a 31-year-old man. Histoenzymatic investigations demonstrated in the myocytes decreased and irregularity of reactions for succinic dehydrogenase, tetrazole reductase and mitochondrial ATPase. In electron microscopy paracrystalline structures, lamellar bodies and concentrically condensed cristae were seen in the mitochondria, and increased glycogen stores outside the mitochondria.
