Turbidimetry with a spectrophotometer was carried out on one hundred semens, and the values were compared with their sperm counts. A rather significant correlation (0.71) was obtained, but it was not enough to make the turbidity as a single quantitative index to evaluate the human semen. The particles in the seminal plasm are not negligible as to t...

A method is described for densitometric evaluation of pancuronium and hydrolysis products, separated by thin layer chromatography. By adaptation of the detection procedure, iodine vapour can be used as visualization reagent. Quantitative determination in relative amounts is possible, because the desorption process of iodine from the spots follows a...

Quantitative measurements of coronary stenoses were made from digital coronary angiograms in 19 patients before and after percutaneous transluminal coronary angioplasty (PTCA). Two methods of measurement were compared. Mean stenosis before PTCA was 67 +/- 10% by the edge detection method and 67 +/- 12% by videodensitometry (difference not significa...

Myxoid chondrosarcoma is a rare tumor of adulthood. An associated nonrandom reciprocal translocation between chromosome 9 and 22 was previously reported in this tumor. We performed cytogenetic and molecular genetic analysis of a myxoid chondrosarcoma derived from the sphenoid bone. Using restriction fragment length polymorphism (RFLP) analysis, we ...
