Dopamine beta-monooxygenase was extensively purified from rat adrenal. The specific activity of the final preparation was approx. 1500 nmol/min per mg protein, which was much higher than the highest yet reported. As judged by gel filtration on Ultrogel AcA22, SDS-polyacrylamide gel electrophoresis, and cross-linking studies, the enzyme appeared to be composed of four identical subunits, each possessing a molecular weight of 88 000. The isoelectric point of the enzyme was estimated to be pH 6.6 in the presence of 8 M urea. Spleen cells from BALB/c mice immunized with rat dopamine beta-monooxygenase were fused to P3-X63-Ag8-653 mouse myeloma cells. From 55 hybrid cells, 10 stable clones secreting anti-dopamine beta-monooxygenase antibody were obtained. Antibody from one clone was coupled to CNBr-activated Sepharose 4B and the monoclonal antibody-Sepharose was shown to be very useful to isolate rat dopamine beta-monooxygenase from crude preparations.

The authors advocate a program for diagnosing Liver-Qi Deficiency Syndrome (LQDS) based on the TCM theory and clinical practice. Through investigation, LQDS was found to be widely existed as latent period or as external manifestation, which occupied 18.85% in Qi Deficiency Syndrome. The subjects were divided into four groups including normal group, Spleen-Qi Deficiency Syndrome (SQDS) group, LQDS with Liver diseases (LD) and LQDS with non-Liver diseases (NLD) group. In order to explore the essence, the simultaneous determinations were done on lactate dehydrogenase (LDH) and its isoenzyme, dopamine beta-hydroxylase (D beta H), trace element Zn and Cu, and other serological indexes such as GPT, TP, Alb, A/G, etc. The results were, the content of LDH and trace element Zn in both LQDS-NLD and SQDS were significantly lower than that of normal group. D beta H reflecting sympathetic nerve function in LQDS-NLD was significantly higher than that of both normal and SQDS group; comparing LQDS-LD and LQDS-NLD group, the content of GPT, LDH, LDH5 and trace element Cu in former was significantly higher than that of the latter, but the content of TP, Alb, A/G, D beta H and Zn in former was remarkably lower than that of the latter. In order to avoid confusion, in studying this syndrome, one should distinguish LD and NLD.
