A kit for colonic cleansing includes a phosphate salt laxative, a flavorant, and an oral rehydration mixture. Use of compounds, and in the treatment of kinase-associated disease states is also described.

The handles are formed as an integrated substantially embracive or curved element, and the element has an aperture at one section for engagement with the mounting of the bottle, and the curved element essentially surrounds the bottle. The amount of protrusion can thus be individually controlled for the write head element and the read head element. These measurements are used to adjust the power delivered to a load independent of the polarity of the connection between the power source and the dimmer circuit.
