Effects of solutions of 0.5% bupivacaine, containing different concentrations of dextrose (0%, 0.5%, 0.8%, 1%, 3%, 5%, 8%) were studied after intrathecal injection in seven (Group A-Group G) groups of 15 patients. The results are summarized as follows: 1. The mean specific gravity of solutions was 1.0065, 1.0087, 1.0092, 1.0094, 1.0152, 1.0198 and 1.0314 (Group A-Group G). These values are isobaric (Group A, B), hyperbaric (Group E, F, G), and slightly hyperbaric (Group C, D) compared to cerebrospinal fluid at 25℃. 2. The mean maximum level of sensory block was increased according to the increment of specific gravity of the solutions. But no significant differences between Group A and B, Group C and D, Group E, F, and G. 3. The mean time of sensory block to T11 was decreased according to the increment of specific gravity of the solutions. 4. The mean time to the expected level (T4) of sensory block at given dosage of each solution was 25.7, 18.4, 9.7 minutes(Group E, F, G, respectively). 5. Complete motor block of the legs was rapid according to the increment of specific gravity of the solutions.

For the refinery waste water treatment, through adsorption experimentation of oil in the emulsified oil water by cheaf carbonized chaffs, the following are founded: 1. carbonized chaffs are inadequate in the adsorption of phenols, 2. they have strong adsorption in emulsified oils 3. and the adsorption has taken place better in the packedbed of carbonized chaffs the oily water permeate through than the agitating tank carbonized chaffs dispersed.
