Vasectomy is a simple and reliable method of male contraception. A growing number of men after vasectomy request vasectomy reversal due to various reasons. The pregnancy rate is lower than the patency rate after vasovasostomy and the pregnancy rate is time dependent.

The autoradiographic micromapping of rocks with various U and Th contents has been performed by means of CR-39 solid-state nuclear track detector (SSNTD). The optical track density was found to be highly correlated (r=0.92) with total alpha emitters activity calculated on the basis of field gamma spectrometric measurements of rock outcrops.

A proteomics approach was used to identify the translation products of a unique synaptic model system, squid optic lobe synaptosomes. Unlike its vertebrate counterparts, this preparation is largely free of perikaryal cell fragments and consists predominantly of pre-synaptic terminals derived from retinal photoreceptor neurones. We metabolically labelled synaptosomes with [(35)S] methionine and applied two-dimensional gel electrophoresis to resolve newly synthesized proteins at high resolution.

The tissue retained 96% of the administered radiolabel while the perfusate contained 4%.

It was found with the whole body autoradiographic method and liquid-scintillation measurements that the compound is rapidly absorbed by whatever routes of administration and it is rapidly taken up by the tissues from the blood stream. In the central nervous system, it reaches higher concentration than methyl-amphetamine and it leaves the central nervous system more slowly.
