Results and discussion

Any other information on results incl. tables

RS-Freetext:
-TER measurements: Time and concentration dependent decrease
in TER. Also a marked increase in pH of treatment solutions
> 500 microg./ml. However, a similar decrease in TER was
seen when the pH was adjusted to neutral pH using 1 M
hydrochloric acid. Some recovery of TER by 24 hr.
-Cytotoxicity: MTT and NRU measurements showed toxicity,
IC50s being 4770 and 3840 microg./ml resp.
