    Notes: Summary By means of the Neo-Timm method it has recently been shown that zinc is present in a fraction of the round clear synaptic vesicles of certain boutons located primarily in telencephalic structures (Pérez-Clausell and Danscher 1985). It is believed that this zinc belongs to a fraction of the total brain zinc which is histochemically active (Frederickson and Danscher 1988) in that it can be visualized by means of e.g. the Neo-Timm and selenium methods (autometallography). The present study is based on the suggestion that the autometallographically developed zinc patterns represent a histochemical quantitative expression of this fraction of the total brain zinc. The different colours of the zinc pattern reflect local variations in the concentration of zinc containing vesicles. Large boutons with a high content of stained vesicles will show up darkly because of fusion of adjoining silver grains while smaller boutons with fewer zinc containing vesicles give rise to yellow staining of various shades. We have exploited this difference in staining pattern by applying computerized optic densitometry to light microscopic sections treated according to the Neo-Timm and the selenium methods, respectively.

    Notes: Summary In a double-blind cross-over study bepridil 900 mg followed by 300 mg daily for 11 days was given to 37 insulin (Type I) or non-insulin (Type II)-dependent diabetic patients. It did not modify the metabolic control of the patients as levels of glucose in blood and urine, doses of insulin and oral hypoglycaemic drugs, energy intake, and the number of hypoglycaemic attacks during therapy were unchanged. The serum concentration of C-peptide was not modified in either type of diabetic patient, and serum insulin in the Type I but not in the Type II patients was slightly higher during active drug treatment. No adverse organotoxic or arrhythmogenic effects or changes in possible atherogenic lipid fractions in serum could be demonstrated during bepridil therapy.
