An unusual case of Whipple's disease is reported. The diagnosis was difficult as the characteristic digestive sign and symptoms (malabsorption, diarrhea, mucosal infiltration by PAS-positive macrophages) were absent. After a ten-year history of seronegative arthritis, myocardiopathy, with aortic insufficiency, basilar pulmonary infiltrates, enlarged lymph nodes, the patient, a 56 years old man, was referred to us for a severe vegetative and neurological dysfunction: stupor, dysarthria, akinesia, hypertonia, hypothermia and abnormal thirst. A CT-scan showed a low-density area of the right hypothalamus, and PAS-positive macrophages were found in a lymph node, in the CSF and in a cerebral biopsy. The patient then received a classical antibiotic treatment, yet the neurologic dysfunction remained severe. Finally, a trial with rifampicin brought a striking improvement of the patient's condition, which has now lasted for three years.

Trandolapril (RU44570) was orally administered to dogs at a daily dose of 2.5, 25 or 250 mg/kg for 13 weeks. After the administration period, 25 and 250 mg/kg groups were observed for recovery for 4 weeks. The results obtained are as follows: 1. One male in the 250 mg/kg group showed decrease of food consumption and body weight, stomatitis, hematemesis, decumbence, hypothermia, and finally loss of reactivity to stimuli. This animal was killed because of these severe changes on the 39th day of administration. Among the surviving animals, a temporary loss of body weight was observed in a few animals of the 25 and 250 mg/kg groups, and a decreased food consumption was sporadically seen in a few animals of the 250 mg/kg group during the administration period. No abnormal changes were found in the clinical observation and water intake in the surviving animals. 2. The changes attributable to the pharmacological effect of RU44570 were a decreased activity of the angiotensin-converting enzyme, increases in plasma renin activity and urine volume, and decreases in specific gravity and concentrations of Na, K and Cl in the urine of every administration group. A decrease in blood pressure and an increase in the PAS and Bowie positive granules in the juxtaglomerular cells were also found in the 25 and 250 mg/kg groups. In addition, thickening of the afferent arteriolar wall of the glomeruli, a basophilic change of the renal tubular epithelial cells, and localized atrophy and hypertrophy of the renal tubules were observed in the 25 and 250 mg/kg groups, and increases in BUN, ALP and creatinine, and a slight dilation of the renal tubules were seen in the 250 mg/kg group. These observations indicated that RU44570 affected renal structure at a dose of 25 mg/kg or more renal function at a dose of 250 mg/kg. The animal killed in a moribund state showed nephrosis which consisted mainly of a moderate dilation of the renal tubules and vacuolation of the renal tubular epithelial cells, stomatitis, severe hemorrhage and necrosis with neutrophil infiltration in the fundus of the glandular stomach, atrophy of the hemopoietic system, and ectopic calcification in the heart, kidneys, stomach, trachea and alveolar wall. Changes in the kidneys similar to those observed in other animals were also detected. These changes suggested that this animal lapsed into a moribund state due to renal dysfunction and the resultant uremia.(ABSTRACT TRUNCATED AT 400 WORDS)

The article describes the features of formation of "spots of Vishnevsky", in general hypothermia. It is proved that the wedge shape of hemorrhages in the gastric mucosa caused by swelling and discrepancy of the paries of stomach pits with the filling of forming wedge-shaped cavity with blood from the arrosive capillaries. It is noted that the dynamics of accumulation of PAS-positive material in the gastric pits in the gastric mucosa in case of total of hypothermia is directly dependent on the growth of intracellular acidosis and disintegration of plasmolemma of parietal cells.

In a study on alcoholics, diabetics, cases of hypothermia, combinations of alcoholism, diabetes and hypothermia as well as 55 controls, ketone body measurements were performed in femoral vein blood, heart blood, vitreous humor, cerebrospinal fluid and urine. Histological investigations were carried out on the kidneys of the deceased. In addition to HE-staining, the cuts were stained with Sudan and PAS to allow differentiation between lipids and glycogens. The degree of stainability in the Sudan stains was correlated with the ketone body concentrations measured. In those cases in which elevated ketone body concentrations were measured, marked fat deposits in the renal tubular epithelial cells could be demonstrated with the Sudan staining method. The higher the stainability the higher the ketone body concentrations. The ketone body concentrations measured in the various body fluids correlated with the intensity of fat stainability.
