The potential value of homoeoprophylaxis in the long-term prevention of infectious diseases, and the maintenance of general health in recipients

Golden, Isaac, homstudy@netconnect.com.au January 2002 (has links)
Homoeoprophylaxis (HP) is the use of homoeopathically prepared substances to prevent targeted infectious diseases in recipients. Its first use in an epidemic of Scarlet Fever was documented in 1801. It has been used throughout the world since then for both short-term and long-term preventative purposes. The effectiveness and safety of Golden�s long-term HP program using homoeopathically prepared substances to prevent targeted infectious diseases in recipients was tested through two research projects. The effectiveness of the program could not be established with statistical certainty given the limited sample size and the low probability of acquiring an infectious disease. However, a possible level of effectiveness of 90.3% was identified subject to specified limitations. Further research to confirm the effectiveness of the program is justified. Statistically significant results were obtained that confirmed the safety of the program both in absolute terms as well as compared to all other methods of disease prevention studied. It also appeared possible that a national immunisation system where both vaccination and HP were available to parents would increase the national coverage against targeted infectious diseases, and reduce the incidence of some chronic health conditions, especially asthma.

THE STRUCTURAL ELUCIDATION OF ANTI-TUMOR AGENTS FROM PLANTS

Tempesta, Michael Steven January 1981 (has links)
The structural elucidations of nine new natural products from Thevetia ahouia, Eremocarpus setigerus, Trichilia hispida, Chrysothamus paniculatus, Uvaria acuminata, Wikstroemia monticola, and Uvaria zelanica are discussed in detail. Also included are some known compounds that were found in these plants. Of the new compounds discussed, two are diterpenes (eremone, chrysothame), two are relatively simple triterpenes (hispidols A, B), two are highly oxidized triterpenes (hispidins A, B), one is a fatty acid derivative (uvaricin), one is a shikimate-derived metabolite (1-epizeylenol), and one has both steroidal and carbohydrate features (3'-OMe-evomonoside). ¹H and ¹³C NMR spectral data are given for all the new compounds. Assignments were made by analogy with model compounds, computer simulation, and ¹H-¹H and ¹H-¹³C decoupling where indicated. High resolution mass spectral fragmentations are given for most of the new compounds, and individual structural assignments made for intense peaks. An X-ray analysis (eremone) was done with all pertinent information included. Most of the compounds have been tested for anti-tumor activity, and several exhibit strong cytotoxicity (hispidins A and B, 3'-OMe-evomonoside, huratoxin, uvaricin).
