It applies to both groups of rats that a significant age-related increase of graded glomerular basement membrane thickness and of measured mesangial area developed. In time, however, this increase was significantly more pronounced in the diabetic than in the nondiabetic group. Tubular and interstitial changes were also observed, both in nondiabetic and in diabetic rats. The importance of using an adequate number of nondiabetic, age-matched controls in studies of the mentioned glomerular changes in diabetic rats is emphasized. A quantitation of the changes in “blind” studies is advisable.","PeriodicalId":6953,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

Inflammatory reactions, varying from small focal to severe, confluent infiltrations, were observed. In inflamed areas the follicular cells were hypertrophied. In perfusion-fixed thyroids focal accumulations of leucocytes adherent to the vessel wall of capillaries and venules could be seen. Studies with fluorescein isothiocyanate conjugated anti-γ-globulin serum revealed that the inflammatory cells contained γ-globulin. In general the intensity of the fluorescence was moderate, but especially in the more severe forms of thyroiditis scattered strongly labelled cells were seen in the interstitium. In the electron microscope the leucocytes adhering to the vessel wall turned out to be almost exclusively lymphocytes in different stages of transformation, from small lymphocytes to immunoblasts. The transformed lymphocytes traversed the vessel wall through the endothelial cell cytoplasm, and not through the intercellular junctions. Most of the inflammatory cells in the interstitium were lymphocytes exhibiting the same continuous picture of transformation as intravascularly. Further differentiated cells, from the plasmablast, through the proplasmacyte to the mature plasma cell were, however, also found. The thyroid follicles and their lumina were invaded by leucocytes, mainly transformed lymphocytes, but also a few granulocytes. Some of the lymphocytes bulged deeply into the cytoplasm of the follicular cell, often indenting its nucleus, but true emperipolesis was not observed. Penetration of the leucocytes into the follicular lumina appeared to take place through the intercellular spaces. The only changes noted in the follicular cells were the hypertrophy and their occasional deformation by the lymphocytes.","PeriodicalId":6953,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

Contrary to the concentration of renin in uterus, the plasma renin concentrations were not increased either during pregnancy or in the post partum period. The renin-substrate concentration was unchanged during the first part of pregnancy but was increased 2–3-fold in the days around delivery. This increase resulted in a corresponding increase in plasma renin activity. It was concluded that the rapid inactivation of uterine renin post partum was due to a local inactivation and not to a release of renin to the blood.","PeriodicalId":6953,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.

Of all persons who had died in Malmo, 46 per cent were necropsied in the first year of the study and 70 per cent in the last (altogether 62.6 per cent). The series was examined in a uniform way at one department of pathology. Carcinoid tumours were found in 1.22 per cent (199 patients) of patients comprised in the entire necropsy series (16,294 autopsies). Bronchial carcinoid accounted for 0.1 percent, the remaining lesions were found in the digestive tract. About 90 per cent of the carcinoids were found incidentally at necropsy. During the same period, 44 carcinoids were diagnosed in surgical specimens examined in Malmo. The average annual frequency of carcinoid in the entire series was about 8.4 per 100,000 inhabitants, which is about 7 times as high as that recorded in the National Cancer Register applying to the whole of Sweden. The value of such country-wide reports is discussed. The carcinoid syndrome is extremely rare and was observed only once during the entire 12-year-period.

The light microscopy is described and the differential diagnosis is discussed. Most of the atypical fibroxanthomas (32 out of 57 cases) were originally diagnosed as soft tissue sarcomas, e.g. fibrosarcoma, dermatofibrosarcoma, neurofibrosarcoma, myosarcoma and unspecified sarcoma. The tumour occurred chiefly in middle-aged and elderly patients; three patients were 15 years old or younger. The median age was 73 years in patients in whom the tumour occurred in the head and neck, and 34 years in patients in whom the tumour developed on the extremities and trunk. The sex ratio (male to female) was almost equal. Follow-up information about 43 patients was available. The follow-up period ranged from 1 year to 25 years with a median of 9 years. Eight patients died from intercurrent disease; all the other 35 patients are alive and well. The clinical course was benign in all but one patient in whom a recurrence developed and metastases to the regional lymph nodes appeared 7 years after the initial excision. The tumour in this case did not differ histologically from the other atypical fibroxanthomas with respect to cellularity, cellular and nuclear atypia or mitotic activity. It is suggested that the recurrence per se might be of prognostic importance.","PeriodicalId":6953,"journal":{"name":"Acta pathologica et microbiologica Scandinavica.
