Blood Treated with Heat, Oxygen/Ozone and UV Irradiation 3.1 Introduction

3.2 Methods 1 Subjects

3.2.3 Trial design and statistical analysis

By taking blood samples prior to the minor autohaemotherapy treatment regime, each of the individuals acted as their own control. Before / after treatment changes were

measured (see Table 3-1). Results were expressed as mean ± sd. Statistical evaluation was performed using the student's t test for paired samples with P < 0.05 as the minimum level of significance.

3.2.4 Methodology

The reagents and equipment used are specified in Appendix 4-4.

Blood (10 ml) was collected into sodium citrate anticoagulant, pharmaceutical grade for

injection (from Quarzlampenfabrik, Dr Muller, Gmbh, Essen, Germany) (2.0 ml of a 3.13 % solution, final blood citrate concentration 0.018 mol/L) and 10 ml of the

anticoagulated blood was placed into the reaction vessel of the Ozon-O-Med equipment (Appendix 2-1). After connecting the thermocouple and gas inlet tube to the machine, a

standard three minutes treatment cycle was initiated, using a pre-set ozone concentration of 15

pg / ml. The med

ical grade oxygen was converted to ozone by silent electrical discharge at ambient temperature, and the mixture of oxygen and ozone was then

bubbled through the sample for 3 min. The temperature of the blood was raised to 42.5° C and the blood was also exposed to UVC irradiation, at a wavelength o f253.7 nm and a dose of 6.0 mJ / cm2, during this treatment. After treatment, the blood was withdrawn

into a syringe, then mixed with 2 ml of a local anaesthetic procaine (Wo), pharmaceutical grade (from Quarzlampenfabrik, Dr Muller, Gmbh, Essen, Germany) and injected

intramuscularly into the gluteal muscle (Appendix 2-2).

A disposable sterile pack is provided for each treatment, containing a syringe, sodium citrate, reaction vessel, gas inlet tube and thermocouple (Appendix 2-2). Each sterile pack is used once only, to exclude cross-contamination of blood during treatment in the Ozon-O-Med equipment.

This procedure was carried out 5 times over a 2 week period. Control subjects had

blood withdrawn, anticoagulated as above but the blood was not treated with ultraviolet light, heat and oxygen / ozone. The untreated blood was reinjected intramuscularly after
