Megestrol acetate in treatment of benign prostatic hypertrophy.

In this study we found no significant effect on benign prostatic hypertrophy due to megestrol using standard clinical criteria. However, there is evidence using urinary drop spectrometer data which makes one suspect that megestrol does have a positive effect. If there is an effect, it is apparently so small as to be undetectable using the clinical protocol of this investigation. Since the urodynamic evidence does indicate a possibility of a positive effect, it appears reasonable to investigate further using a different protocol - perhaps a higher dosage and/or a more controlled test population.

A novel biotinylated adenylate analogue derived from pyrazolo[3,4-d]pyrimidine for labeling DNA probes.

A novel dATP analogue, 3-[5-[(N-biotinyl-6- amiocaproyl)amino]pentyl]-1-(2-deoxy-beta-D-erythro-pentofuranosyl )-1H-pyrazolo[3,4-d]pyrimidin-4-amine 5'-triphosphate (9, bio-13-dAPPTP), which is modified at the 3-position with a flexible linker arm bearing a terminal biotin moiety, has been synthesized. This nucleotide is readily incorporated into DNA probes by nick translation. These probes hybridize to complementary targets as well as probes labeled with bio-dUTP, as judged by slot blot. When incorporated into oligonucleotides, they do not cause the loss of hybridization efficiency that an N-6-substituted adenine nucleotide does when incorporated into the same sites in the oligonucleotide.
