The alkali solution concentration and steam explosion process condition were optimized by testing the solubility of soft cellulose after steam explosion before and after treatment towards aq.NaOH with various concentration. It was concluded that the soft cellulose can dissolve in the 9% aq.NaOH solution completely under the condition of explosion pressure 3.0Mpa and explosion time 60s. At the same time, the influence of sweller-thiourea on the new aq. alkali soluble cellulose/NaOH solution was studied in this paper. The dissolving phenomena and the steam explosion mechanism of soft cellulose were discussed.

The results showed that two of the ball cactuses tested could growth well in solution culture , in which the growth rate was significantly higher than or equal to that in peatmoss culture. Among the four solution culture formulae , formula 4 had the highest biomass increment and uptake of N , P and Kfor Ferocactu horridus. The biomass of Echinopsis calochlora did not differ significantly among the four formulae , but significantly increased higher than medium culture. This study indicated that ball cactuses could grow well in nutrient solution culture.

Results In three Hank's solution infused cochleas, the thresholds of IC potential were kept in the normal level and no hair cell loss was found 14 days after the beginning of the infusion, suggested that the pump implantation and Hank's solution infusion had no significant effects on the cochlear functions. In contrast, threshold shifts of IC potentials and hair cell loss were found in two BSO infused animals, suggested that the infused solution had distributed into the whole cochlea.
