The veins of the spermatic cord are abnormally wide and tortuous in both primary and secondary varicocele. The primary form is by far the more common; among the causes of secondary varicocele are renal tumor (SPITTEL et coIl. 1959), hydronephrosis (WHITE 1914), aberrant renal artery (CAMPBELL 1944), and arching of the spermatic artery over the renal vein (NOTKOVICH 1955). The pathogenesis of primary variococele has not been clarified. BRODNY et coIl. (1955) stated that it most often starts at puberty and occurs in about 10 % of the male population, on the left side in about 90 %, bilaterally in 8 % and on the right side in 2 % of these. The clinical importance and treatment of the condition as well as the pathogenesis are dealt with in another report by the present authors (FRITjOFSSON et coll.).The scrotal veins may be considered as lying in two groups: a deep group and a surface network group (JAVERT & CLARK 1944). The deep system comprises the pampiniform plexus, the internal and external spermatic veins and the ductus deferens veins. The pampiniform plexus consists of a network of veins which originate in the testis and epididymis; it is drained by the three aforementioned larger vessels. The internal spermatic vein passes through the
In long-term daunorubicin treated rabbits increased myocardial accumulation of 99Tcm-pyrophosphate and 99Tcm-gluconate of a varying degree were recorded, visible at gamma camera examination in more than half of the animals. Chronic cardiomyopathy morphologically and topographically different from the ischemic myocardial injury was demonstrated in most animals at light microscopic examination. The myocardial abnormalities were classified in qualitative and quantitative scores and compared with the degree of isotope accumulation. The rabbits receiving a large single dose of daunorubicin had slightly increased isotope accumulation in the myocardium but no histopathologic changes.
The value of using fat emulsion as an intravesical medium on examination of bladder tumours with computed tomography, based on a series of 46 patients, and the influence of recent transurethral resection on the bladder wall, are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
