A NEW BIOLOGICAL SCREENING SYSTEM FOR LOCAL ANAESTHETICS BY INHIBITION MOBILITY OF TETRAHYMENA PYRIFORMIS
An alternative in vitro approach to drug screening has been the use of human cell cultures for antiviral agents and microbial cell cultures for the assessment of the carcinogenic potential of selected compounds. A number of protozoan species have been also used as drug screens for anti-protozoal agents. The ciliated protozoan Tetrahymena pyriformis species has been widely utilised as a dru...
متن کاملElectron-microscopic observations on the macronuclear development of Stylonychia mytilus and Tetrahymena pyriformis (Ciliophora-Protozoa).
This report describes an ultrastructural investigation of macronuclear development following conjugation in Stylonycltia mytilus (a spirotrichous ciliate) and Tetrahymena pyriformis (a holotrichous ciliate). In S. mytilus, polytene chromosomes are formed in the young macronucleus (macronuclear Anlage). They are subsequently broken between the bands by 'membranous' partitions; the assembly of th...
متن کاملRibosome Synthesis in Tetrahymena Pyriformis
The cellular site of synthesis of ribosomal RNA in Tetrahymena pyriformis was studied by analyzing the purified nuclear and cytoplasmic RNA from cells pulse labeled with uridine-(3)H. The results of studies using zonal centrifugation in sucrose density gradients show that the ribosomal RNA is synthesized in the nucleus as a large precursor molecule sedimenting at 35S. The 35S molecule undergoes...

متن کاملA Temperature-sensitive Mutant in Tetrahymena Pyriformis,
After treatment with nitrosoguanidine a mutation to temperature sensitivity was obtained in Tetrahymena pyriformis, syngen 1. The trait is controlled by a recessive allele, ts, at a locus linked to serotype locus T. I S is completely recessive, unlike any other allele studied in this organism, and the heterozygotes do not show vegetative assortment. The cross which revealed the linkage of ts an...
