چکیده

The sensitivity of protozoa, and particularly ciliated protozoa, to environmental changes suggested a study on the physiological responses arising from exposure to toxic compounds. Tetrahymena pyriformis was used as a test organism in a set of miniaturized assays. The physiological response of this ciliate was assessed in terms of adenosine-5'-triphosphate content and acid phosphatase activity after exposure of the cultures of T. pyriformis to four toxicants: copper, zinc, Triton X-100, and cycloheximide. In the range of concentrations used, stimulation and inhibition of these two parameters were observed. The correlation between the two parameters is analyzed.

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...

Activity of Ribonuclease, Acid Phosphatase, and Phosphodiesterase in Tetrahymena Pyriformis during Growth

Studies on the nucleolytic activity of cell homogenates of Tetrahymena pyriformis indicated that enzyme activity was, among other factors, a function of the age of the culture (1, 2). It was shown that the specific activities of ribonuclease (RNase) (EC 2.7.7.h) and acid phosphatase (APase) (EC 3.1.3.2) in crude homogenates prepared from stationary-phase cultures were consistently higher than t...

Axenic Tetrahymena pyriformis, syngen 1, mating type II cells were grown in Cox's defined medium. When washed and transferred into nonnutrient dilute salt solution or resuspended in the defined medium, the intact cells secrete acid hydrolases into the medium. Cells starving in the salt solution release in 5 hr about two-thirds of their beta-glucosidase, beta-N-acetylglucosaminidase, alpha-gluco...

Background: Elicitors can trigger defense responses and activate specific genes involved in secondary metabolite biosynthesis. Objective: For understanding SA-treatment signaling pathway we determined defense-related compounds and enzymes in S. marianum hairy root cultures. Methods: 28 day old hairy roots were treated by salicylic acid (6 mg/50 ml culture) for different times (24, 48, 72, 96...

The effect of cholesterol on ubiquinone and tetrahymanol biosynthesis in Tetrahymena pyriformis.

The biosynthesis of ubiquinone-8 from radioactive mevalonate by cultures of Tetrahymena pyriformis is demonstrated. Under normal conditions the incorporation of this radioactive precursor into ubiquinone and the triterpenoid alcohol tetrahymanol reflects the amounts of these two compounds in the cell. Growth of T. pyriformis in the presence of cholesterol results in a complete inhibition of inc...
