The characteristics of the use and the levels of diffusion of nonconventional medicine

The national trends of the utilisation of non conventional therapies suggest that an increasing number of patients employ remedies that are outside the mainstream of what has been defined as conventional western medicine. The extent to which these practices have clinical efficacy according to biomedical criteria is a matter of ongoing debate. It may be that independent of any such efficacy, the attraction of alternative medicine is related to the power of its underline shared beliefs and cultural assumptions. The fundamental premises are an advocacy of nature, vitalism, "science" and spirituality. For patients, who choose alternative medicine, the most important reason to abandon conventional therapies could be to move from the sterile "high-tech" realm of official medicine to a more intimate "high-touch" intervention offered by non-physicians.

Endothelin antagonist treatment for successful liver transplantation from non-heart-beating donors

BACKGROUND: With the shortage of cadaveric donors, non-heart-beating donors (NHBDs) are a potential source of liver allografts. However, warm ischemic injury in NHBDs seriously affects the viability of graft liver. Endothelin (ET)-1 has been reported to be involved in the hepatic microcirculatory disturbances after ischemia-reperfusion. METHODS: In a porcine orthotopic liver transplantation model, changes in the serum and liver tissue ET-1 concentration were measured and the effects of an ET receptor antagonist, TAK-044, were evaluated. After cardiac arrest of the donors, liver allografts were subjected to 90 min of warm ischemia, flushed, and preserved for 4 hr at 4 degrees C. The pigs were divided into two groups: a control group (no drug treatment) and a drug-treated group, in which donors and recipients were treated with TAK-044 (10 mg/kg body, drip intravenous injection). Both groups had six donor/recipient pairs. RESULTS: -The ET-1 concentration in the hepatic venous blood increased after reperfusion of the graft in the control group recipients. ET-1 in the graft liver significantly increased during the cold preservation period. TAK-044 treatment significantly increased recipient 7-day survival rate. After reperfusion of the graft, the concentrations of serum liver enzymes and arterial lactate in the drug-treated group were significantly lower than in the control group. The postoperative increase in portal venous pressure was significantly reduced in the drug-treated group. Measurements of liver enzymes in the washed-out preservation fluid at the time of graft rinsing indicated that TAK-044 treatment of the donors significantly suppressed liver enzyme release during ischemia. CONCLUSIONS: These findings indicate TAK-044 treatment has protective effects on postoperative function of hepatic allografts procured from NHBDs.
