Genetic, neuropathological and biochemical studies suggest strong links between cholesterol, the apolipoprotein E (APOE) and Alzheimer’s disease (AD), both in humans and in animal models of the disease. From the literature and our work, we can predict that transient increase of the levels of cholesterol at the membrane of neurons would profoundly affect the processing of the transmembrane Amyloid Precursor Protein (APP) by triggering its clathrin dependent endocytosis and the resulting production of amyloid-β (Aβ) peptides. Here, we will review these data together with structural and molecular dynamic studies that characterized the role of cholesterol on APP conformation and positioning at the membrane. Specifically decreasing brain cholesterol or replacing it with plant sterols crossing the blood brain barrier appear like promising strategies to either delay or counteract the development of sporadic AD.

Extracellular Materials

Ruthenium red has been used as a stain to demonstrate a variety of extracellular materials, especially acid mucopolysaccharides. It also reacts with certain intracellular and extracellular lipids. Since biochemical studies in our laboratory demonstrated the presence of a variety of monosaccharides in human hair ruthenium red staining procedures were adopted in order to evaluate the presence and morphological location of acid oligosaccharides in the keratinized aspect of hair.

And Control

Hypophysectomy of the rat renders this animal deficient in the hormones of the anterior pituitary gland, thus causing many primary and secondary hormonal effects on basic liver functions. Biochemical studies of these alterations in the rat liver cell are quite extensive; however, relatively few morphological observations on such cells have been recorded. Because the available biochemical information was derived mostly from disrupted and fractionated liver cells, it seemed desirable to examine the problem with the techniques of electron microscopy in order to see what changes are apparent in the intact liver cell after hypophysectomy. Accordingly, liver cells from rats which had been hypophysectomized 5-120 days before sacrifice were studied. Sham-operated rats served as controls and both hypophysectomized and control rats were fasted 15 hours before sacrifice.

The renal radiopharmaceutical preparations 99mTc-DMS and 99mTc-GH were examined chemically, biologically and clinically. Both preparations are of high radiochemical purity. The biodistribution of both preparations was examined in experimental animals at different time intervals, from 15 min to 4 hr; the percentage of incorporation of 99mTc-DMS into kidneys is much higher (29.4% to 52.0%) than that of 99mTc-GH (12.80% to 22.20%). Both preparations accumulate to a greater extent in the renal cortex than in the medulla.The most suitable time for renal scintigraphy for "mTc-DMS is 90-150 min while for 99mTc-GH it is 60-90 min. It is concluded that 99mTc-DMS is more suitable for static scintigrams on the scanner and 99mTc-GH for dynamic studies with the gamma camera.

Increased Activity

SummaryA 26-year-old man with a previous history of external twin bursitis was remitted to our Department for a bone scintigraphy. Before the study, the patient performed an elevated number of intense sprints. Bone scintigraphy showed a bilaterally increased activity in both anterior rectum muscles suggesting rhabdomyolysis. Biochemical studies and MRT confirmed the diagnosis.
