Relation between the therapeutic effect of moxibustion in treating arthralgia and SP and enkephalin in nervous tissues.

Moxibustion can accelerate the relief of arthralgia of rats suffering from adjuvant arthritis. At the same time, it promotes the recovery of SP in the sciatic nerve, and maintains SP and leu-enkephalin at a higher level in the lumbar spinal cord. The results show that the therapeutic effect of moxibustion in treating arthralgia bears some relation to activating the spinal enkephalin system and modulating the function of primary afferent neurons.

Removal and recovery of chromium(III) from aqueous solutions by a spheroidal cellulose adsorbent.

The removal and recovery of chromium(III) (Cr3+) from aqueous solutions with a spheroidal cellulose adsorbent containing the carboxyl anionic group was investigated. The adsorption of Cr3+ ion on the adsorbent has been found to be time, concentration, pH, and temperature dependent. The adsorption process follows both the Freundlich and Langmuir adsorption isotherms, and has been found to be endothermic (enthalpy change, deltaH = 31.35 kJ/mol). The Cr3+ ion adsorbed on the adsorbent can be recovered by treating with a sodium hydroxide (NaOH) or hydrochloric acid (HCl) solution in one of two methods, static desorption or mobile desorption (column operation). A 1.2 mol/L HCl aqueous solution was finally chosen to recover the Cr3+ ion using column operation. The recovery percentage is approximately 85.2%. The exhausted column can be chemically regenerated by treatment with 1 mol/L NaOH aqueous solution and no dismantling is required. The adsorption mechanism is explained on the basis of complexation and ion exchange, between which the complexation adsorption is predominant.
