The combined effect of surgical treatment and consumption of so-called “CoD™ tea” (containing Uncaria guianensis, U. tomentosa and Tabebuia avellanedae) on expression of c-myc, Ha-ras, Bcl-2, Ki-ras and p53 key onco/suppressor genes, the carbohydrate antigen (CA19-9) and carcino-embryonic antigen (CEA) tumour markers in blood samples of patients with colorectal cancer (CRC) were investigated. Expression of genes followed the effect of the surgical treatment combined with neoadjuvant chemotherapeutic treatment; this may predict the outcome of carcinoma. Moreover their expressions might show possible additional effect of supportive therapy, e.g. CoD™ consumption. The antioxidant capacity of blood was also examined. Blood samples were taken at the day of, and one week, 3, 6 and 12 months after the surgical treatment. During that period patients got 0.25 l standard portion of CoD™ tea three times a day. The surgical treatment and neoadjuvant therapy were able to suppress the expression of c-myc, Ha-ras, Bcl-2, Ki-ras, p53 genes up to the twelfth month. Moreover, CoD™ tea together with conventional treatment caused a strong decrease in the expression of c-myc and Ha-ras oncogenes in comparison to the non-consumer control.

The addition of synthetic (E)-anethol to the known attractant phenylacetaldehyde synergized attraction of the cotton bollworm Helicoverpa armigera, the blend invariably catching 4 to 6 times more than phenylacetaldehyde on its own. Highest catches were recorded by the 1:1-3:1 blends. The addition of salicyl aldehyde, ±linalool, (R)-(+)-limonene, 2-methoxybenzyl alcohol and 4-methoxybenzyl alcohol (compounds described earlier in the literature as co-attractants for H. armigera), increased catches when added to phenylacetaldehyde. However, the addition of these compounds did not increase catches of the (E)-anethol+pheny- lacetaldehyde blend. When directly compared with performance of the synthetic pheromone, the (E)-anethol +phenylacetaldehyde blend caught an average of 27% of the catch in pheromone baited traps. On an average 79% of moths caught in traps with the (E)-anethol+phenylacetaldehyde blend were females, while traps with pheromone caught only males. The (E)-anethol+phenylacetaldehyde blend described in this study may form the basis for the development of an efficient bisexual lure for H. armigera AFTER further optimization.
