Polyethylene glycol-1000 (PEG-1000) induced fusion of HPRT (E.C. 2.4.2.8) deficient Chinese hamster cells with alpha-galactosidase A (E.C. 2.3.1.22) deficient cells from a patient with Fabry's disease yielded hybrids which contained both human and hamster HPRT, G6PD (E.C. 1.1.1.49), and APRT (E.C. 2.4.2.7) and Chinese hamster alpha-galactosidase B. Thus PEG-1000 mediated somatic cell fusion led to reexpression of Chinese hamster HPRT. It did not restore the expression of human alpha-galactosidase. Since PEG-1000 treatment of HPRT- Chinese hamster cells in the absence of human cells yielded no HPRT+ cells, it is concluded that the element responsible for the restoration of rodent HPRT was contributed by the human cells and not by the agent employed to promote fusion.

Hypertrophic cardiomyopathies have an estimated prevalence of 1/500. The analysis of the genes coding for the 10 most commonly involved sarcomeric proteins, fails to detect a mutation in about one third of cases. In some of these cases, cardiomyopathy can be attributed to a genetics storage disease with enlarged glycogen vacuolss (PRKAG2 deficiency, Danon disease, Pompe disease) and/or lysosomol vacuoles (Donon disease, Pompe disease, Fabry disease). These diseases all have in common a short PR interval. PRKAG2 deficiency is due to a dominant mutation of the gamma2 subunit of the cardiac AMP kinose. It leads to a storage cardiomyopathy which may be associated with sudden death in 10% of cases, due to ventricular arrhythmia or auriculoventricular blocks. Danon disease is an X-linked dominant inherited disease characterized by cardiomyopathy, squeletal myopathy and mental retardation. Cardiac transplantation is indicated in both affected men and women. In the infantile form of Pompe disease, enzyme replacement therapy with olglucosidase alpha shows efficacy on cardiac failure with a significant regression of ventricular hypertrophy on ECG, echocardiography and radiography

Urine microscopy is an important tool for the diagnosis and management of several conditions affecting the kidneys and urinary tract. In this review, we describe the automated instruments, based either on flow cytometry or digitized microscopy, that are currently in use in large clinical laboratories. These tools allow the examination of large numbers of samples in short periods. We also discuss manual urinary microscopy commonly performed by nephrologists, which we encourage. After discussing the advantages of phase contrast microscopy over bright field microscopy, we describe the advancements of urine microscopy in various clinical conditions. These include persistent isolated microscopic hematuria (which can be classified as glomerular or nonglomerular on the basis of urinary erythrocyte morphology), drug- and toxin-related cystalluria (which can be a clue for the diagnosis of acute kidney injury associated with intrarenal crystal precipitation), and some inherited conditions (eg, adenine phosphoribosyltransferase deficiency, which is associated with 2,8-dihydroxyadenine crystalluria, and Fabry disease, which is characterized by unique urinary lamellated fatty particles). Finally, we describe the utility of identifying "decoy cells" and atypical malignant cells, which can be easily done with phase contrast microscopy in unfixed samples.
