Effect Of Lymph Drainage Research Articles

The effect of lymph drainage on the myoelectric manifestation of vastus lateralis fatigue: Preliminary results.

Variations in surface electromyograms (EMGs) collected from the vastus lateralis muscle during isometric fatiguing contractions were investigated pre-post lymphatic drainage (intervention group, N=3) and pre-post rest (control group, N=3). The slope of conduction velocity and of EMG amplitude and spectral descriptors was computed from the start to the failure time; the instant after which subjects could not endure contractions. When compared to subjects in the control group, those in the intervention group endured longer. Similarly, muscle fatigue affected to a lesser extent EMGs following lymphatic drainage than following rest. These preliminary results suggest the lymphatic drainage may potentially delay muscle fatigue.

Effects of using different ways to block "gut-lymph" pathway on intestinal ischemia/reperfusion injury

Objective To compare the effects of using different ways to block pathway on endotoxin,cytokine,and lung function.Methods Fifty special pathogen free (SPF) leveled SD mice were randomly divided into 5 groups:control group (blank) ; sham group (sham) ; ischemia/reperfusion group (I/R) ; ischemia/reperfusion plus lymph duct ligation group (I/R + L) ; and ischemia/reperfusion plus lymph drainage group(I/R+D) (n=10).Results I/R,I/R+L and I/R + D groups had significantly higher levels of endotoxin and cytokine in serum than in blank group and sham group [endotoxin in I/R vs.I/R + L vs.I/R + D vs.blank vs.sham:(0.039 4 ±0.002 5) vs.(0.029 9 ±0.003 9) vs.(0.028 9 ±0.003 1) vs.(0.025 2 ±0.004 2) vs.(0.026 2 ±0.001 3) Eu/ml; tumor necrosis factor-α(TNF-α):(49.92±7.48) vs.(36.85 ± 13.46) vs.(27.67 ± 10.12) vs.(18.86 ± 12.70) vs.(25.80±11.19) ng/L; interleukin (IL)-6:(41.78±9.75) vs.(19.14±1.48) vs.(19.20±4.14)vs.(8.69 ± 0.76) vs.(11.57 ± 2.90) ng/L;P ＜ 0.05 respectively).After blocking lymph duct,I/R +L and I/R + D groups had remarkably lower levels of endotoxin and cytokine in serum,and nitric oxide (NO) and inducible nitric oxide synthase (iNOS) in the lung than in I/R group (P ＜0.05),The concentrations of NO,total nitric oxide synthase (tNOS),and iNOS in I/R + L and I/R + D groups were extraordinarily higher than in sham group (P ＜ 0.05).Conclusion By blocking gut-lymph pathway,both lymph duct ligation and lymph drainage could reduce the local intestinal tract inflammation and distant organ injury incurred by intestinal ischemia/reperfusion,and the effect of lymph drainage was superior to lymph duct ligation,but with no significant difference.

Effects of lymph drainage on multiple organ injury of rats with traumatic hemorrhagic shock

Objective To observe the effect of shock lymph drainage on multiple organ injury of rats with traumatic hemorrhagic shock (THS) and discuss the relating mechanism. Methods Male Wistar rats were divided into control group, lymph drainage group and lymph return group. The THS model was established in lymph drainage group and lymph return group, when the shock mesenteric lymph was drained in lymph drainage group. The change of the mean arterial pressure ( MAP), the biochemical indices of liver, kidney, myocardium and acid-base, the morphology, ATP contents and ATPase activities of lung, kidney, liver and myocardium were observed. Results The MAP at multiple time points after 80 minutes of infusion, the ATP contents and ATPase activities of multiple organs in lymph drainage group were higher than those in lymph return group. Multiple biochemical indices in lymph drainage group were superior to those in lymph return group, with statistical difference. The inflammation, congestion, degeneration and necrosis were found in organs of lymph return group, but only mild lesions could be seen in lymph drainage group. Conclusions The shock lymph drainage can alleviate multiple organ injury of THS rats, mechanism of which is correlated with improvement of the energy metabolism and maintenance of MAP and acid-base status.
