Physiologic effects of rhythmical massage: a prospective exploratory cohort study.

OBJECTIVE: This study was performed to characterize the physiologic effects of rhythmical massage (RM), an anthroposophic therapy whose effectiveness is supported by empirical observations and a prospective observational study. METHODS: Patients referred to RM at the Paracelsus Hospital Richterswil for any indication were continuously enrolled. They received an average of 10 RM sessions, which included not only the massage but also therapeutic rest in the supine position immediately thereafter. Effects of RM on surface temperature and on heart rate variability (HRV) were determined with infrared imaging (IRI) and electrocardiography (ECG), respectively. IRI of the patients' dorsal region was performed without clothes, in standing position, at the start and at the end of two waiting periods before and after RM. ECG was performed from the beginning of the first waiting period until the end of the second one. RESULTS: Results on IRI from 9 and ECG from 11 patients could be analyzed. RM led to an immediate increase in dorsal temperature. Furthermore, comparison of the IRI images for consecutive RM sessions showed a tendency toward improved warmth distribution as a progressive therapy effect. Analysis of the EGC results recorded during the waiting periods-in the sitting position--showed a significant increase of HRV after RM, as detected by the standard deviation of the beat-to-beat periods and a relative increase of low-frequency power. During the course of the RM sessions, the change in HRV during the therapeutic rest period depended on the initial value: Low initial values were enhanced, whereas high ones were reduced. CONCLUSIONS: RM led to an immediate increase in the patient's dorsal surface temperature, as well as increased HRV and sympathetic stimulation. In the long term, RM resulted in a progressive improvement of warmth distribution and regulation of the resting HRV.

In vitro investigation into the potential of a mistletoe extract to alleviate adverse effects of cyclophosphamide.

OBJECTIVES: Mistletoe extracts have been shown to provide deoxyribonucleic acid (DNA)-stabilizing effects in human peripheral blood mononuclear cells (PBMC) in vitro. We investigated the effect of a mistletoe extract on PBMC with and without concomitant treatment with cyclophosphamide and compared mitochondrial activity and replication of normal PBMC with that of a T-cell leukemia cell line. DESIGN: The experiments were performed with PBMC of healthy blood donors and the T-cell leukemia Jurkat cell line. Cells were pre-incubated with mistletoe extract for 60 to 65 hours. 4-hydroperoxycyclophosphamide (4-hpc, precursor of 4-hydroxycyclophosphamide) was added for 2 hours, after which mitochondrial activity and replication were measured. All experiments were randomized and blinded. MAIN OUTCOME MEASURES: Cell mitochondrial activity and replication were assessed with spectrophotometric analysis of WST-1 reduction and BrdU incorporation. RESULTS: The application of 4-hpc consistently reduced mitochondrial activity and replication of PBMC and Jurkat cells. Mistletoe extract strongly enhanced PBMC mitochondrial activity and replication (with or without 4-hpc) and partially inhibited Jurkat cell replication (with 4-hpc only). Compared to mistletoe untreated cells, enhancement ofPBMC mitochondrial activity by mistletoe extract was independent of treatment with 4-hpc, but enhancement of PBMC replication by mistletoe extract was stronger when treated with 4-hpc. CONCLUSIONS: Mistletoe extract strongly stimulated healthy PBMC but not malignant Jurkat cells. In addition, mistletoe extract seemed to partially protect healthy PBMC-but not malignant Jurkat cells-from the cytostatic effect of 4-hpc. The results motivate further preclinical and clinical investigations of mistletoe extracts as an adjuvant medication in cancer therapy to alleviate side effects of conventional therapy.

Effect of low doses and high homeopathic potencies in normal and cancerous human lymphocytes: an in vitro isopathic study.

OBJECTIVES: Biologic effects of high homeopathic potencies can be studied in cell cultures using cell lines or primary cells. We hypothesized that primary cells would be more apt to respond to high potencies than cell lines, especially cancer cell lines. We set out to investigate the effects of low doses and high homeopathic potencies of cadmium chloride, respectively, in an intoxication model with human primary lymphocytes compared to a human leukemia cell line (Jurkat). DESIGN: Cells were pretreated with either low concentrations (nM-microM) or high potencies (pool 15-20c) of cadmium for 120 hours, following which they were exposed to a toxic treatment with a range of cadmium concentrations (8-80 microM) during 24 hours. Cell viability was eventually assessed by use of the MTS/PES assay. Controls included a vehicle (NaCl 0.9%) for the low concentrations of cadmium or water 15-20c for cadmium 15-20c. A total of 34 experiments were conducted, 23 with low concentrations and 11 with high potencies of cadmium. Data were analyzed by analysis of variance. RESULTS: Pretreatment with low concentrations or high potencies of cadmium significantly increased cell viability in primary lymphocytes after toxic challenge, compared to control cells (mean effect +/- standard error = 19% +/- 0.9% for low concentrations respectively 8% +/- 0.6% for high potencies of cadmium; p < 0.001 in both cases). The pretreatment effect of low doses was significant also in cancerous lymphocytes (4% +/- 0.5%; p < 0.001), albeit weaker than in normal lymphocytes. However, high homeopathic potencies had no effect on cancerous lymphocytes (1% +/- 1.9%; p = 0.45). CONCLUSIONS: High homeopathic potencies exhibit a biologic effect on cell cultures of normal primary lymphocytes. Cancerous lymphocytes (Jurkat), having lost the ability to respond to regulatory signals, seem to be fairly unresponsive to high homeopathic potencies.
