Pharmaceutical composition for the management of tumors

The present invention relates to the effect of naturally occurring compounds on tumor development. As an example of proof, we used low; non-toxic doses of three compound e.g. Calcium D-glucarate, a naturally occurring Ca++ salt of D-glucaric acid; Nicotinamide (NA), a naturally occurring vitamin and butyric acid (BA), a naturally occurring saturated short chain fatty acid. 7,12 dimethylbenzanthracene (DMBA), which is a very potent skin carcinogen and is an environmental pollutant, was used for skin tumor development. Experiment was performed upto 30 weeks. All the above-mentioned compounds were used either alone or concomitantly any two or all the three. In the positive control group 100% tumorigenesis was attained in 28 weeks, use of single compound led to the inhibition of DMBA induced tumorigenesis between 33 to 47%, use of two compounds resulted in the 73 to 80% reduction in tumorigenesis but the concomitant use of three compounds resulted into 100% inhibition of tumor development at the end of 30 weeks. This led us to conclude that the concomitant use of Cag, NA and BA in combination of two is useful for preventing skin tumor develoment for a sort or long period of time. But the concomitant use of all the three compounds, as described, exhibited the perfect synergistic effect in preventing the tumor development completely. This strategy should be equally effective in the management of benign and possibly malignant tumor in any organ caused by any mean.

A magnetic resonance spectroscopy and imaging device and method of use for accurately delineating the lateral extent and depth of a skin tumor. The device includes a radiofrequency tuned circuit with an antenna in the shape of an acupuncture needle that is positionally-controlled using a mechanical actuator to provide high-contrast spatial images of skin tumors with sub-millimeter lateral and depth resolution. The device is used by dermatologists to provide accurate spatial demarcations of skin tumors, which facilitate the complete excision of a tumor in the first pass of the Mohs micrographic surgical procedure. Different sizes and shapes of the needle antenna provide advantages for sensitivity, image resolution, and capabilities to impact treatments. A hollow needle antenna provides for a capability of the inventive device to affect treatment of a skin tumor by injecting a chemical agent while monitoring chemical and spatial aspects of the tumor, and by aspirating cancer tissue to remove the tumor and related chemical treatment agents.
