A non-invasive method of blood glucose evaluation by tear glucose measurement, for the detection and control of diabetic states.

The development of a quick, simple and sufficiently reliable method for tear glucose measurement is described. The method, based on a color reaction with triphenyl-tetrazolium chloride on special filter paper strips imbibed with tears, showed results which related favorably with parallel blood glucose levels of the same patients, already in the first stage of its development. Being non-invasive, the proposed method could be of important practical benefit for the detection and monitoring of diabetics, thus obviating the necessity of invasive blood sampling inherent to existing biochemical techniques.

Effects of parathyroid hormone on exocrine pancreatic secretion in parathyroidectomized dogs.

The effects of intravenous parathyroid hormone (PTH) on steady state Secretin-induced pancreatic secretion were studied in seven dogs before and after parathyroidectomy. Free flow of pancreatic juice was obtained by direct cannulation of the main pancreatic duct (the minor duct being ligated) : a gastric fistula prevented the entry of gastric acid into the duodenum. In the normal dog PTH caused a significant increase in volume and bicarbonate concentration, reciprocal change in chloride and no change in total protein concentration.

Dermatitis artefacta.

A case of dermatitis artefacta is reported. The lesions were shown to contain silver and were probably caused by a silver nitrate caustic stick. The patient never admitted to having produced these lesions.

Effects of prolonged administration of high molecular levan on arterial blood gases, oxygen transport and acid base balance in rabbits.

The effect of daily intraperitoneal injections of 100 mg of high molecular levan for 4-6 weeks on a number of physiological parameters was studied in rabbits. The parameters studied included whole blood pH, blood gases and acid-base balance. Control rabbits were similarly treated with physiological saline.
