OBJECTIVETo evaluate the effect of manual lymph drainage on chronic extremity lymphedema.

METHODSFifty patients with chronic lymphedema of extremity were treated with manual lymph drainage (MLD) complex decongestion therapy. Among them, 29 had primary lymphedema, 21 had secondary lymphedema. 42 had lymphedema of lower extremity and 8 had lymphedema of upper limb. The result of treatment was evaluated with measurement of circumference of extremities and edema fluid in tissue with Multiple-frequency bioelectrical impedance analysis.

RESULTSAfter 1-2 treatment courses, all 50 patients showed significant decrease of circumference of lymphomatous limbs (P < 0.05) and remarkable reduction of accumulated edema fluid in tissue (P < 0. 05). There was highly correlation between the decrease of limb circumference and edema fluid in tissue (r(s) = 0.774, P < 0.01).

CONCLUSIONSMLD complex decongestion therapy is effective for the treatment of chronic lymphedema of extremity.

OBJECTIVE: To develop a high-performance liquid chromatographic method for determination of ketamine and norketamine in blood and urine. METHODS: The compounds were extracted from blood or urine by liquid-liquid extraction using toluene after blood or urine was adjusted pH to 14. The extracts were analyzed by HPLC. RESULTS: Linear limits of ketamine and norketamine determination in blood ranged from 0.05 microg/mL to 10 microg/mL (R2 > 0.9993) and in urine ranged from 0.01 microg/mL to 200 microg/mL (R2 > 0.9995). Limits of detection (LODs) for ketamine and norketamine were 0.006 microg/mL and 0.003 microg/mL (S/N > or = 3), respectively. The mean extraction recovery was over 82.4% and its coefficients of variation were less than 10.0% for ketamine and norketamine. Concentration-time curves and urinary drug velocity curves of ketamine norketamine were obtained by determinations of them in blood and urine in rat using the developed method. CONCLUSION The method is sensitive, simple, rapid and suitable for determination of ketamine and norketamine in blood and urine for toxicological and clinical pharmaceutical analysis.
