Study of the Inhibitory Effect of <i>Coix lachryma-jobi</i> L. <i>var. ma-yuen</i> Stapf on Carcinogenesis and Inflammation / 日本補完代替医療学会誌

Adlay(<i> Coix lachryma-jobi</i> L. <i>var. ma-yuen</i> Stapf ) is a grass crop that has long been used in traditional medicine as a nourishing food. This study investigated the inhibitory effects of adlay related substances on carcinogenesis and anti-inflammation. The hot water extract of all parts of adlay (CRD) were compared with the hot water extract of dehulled adlay (yokuinin). In addition, the Monoolein and Trilinolein components of adlay were compared.<br> As a screening date, antiproliferative effect of human cancer cells showed weak biological potency on physical dose response. Prevention effect of carcinogenesis and anti-inflammatory effect were also observed in all samplles. CRD showed stronger anti-UVB inflammatory effect than that of yokuinin; while yokuinin showed stronger anti-heating injury inflammatory effect than that of CRD. Moreover, Monoolein showed stronger effect than Trilinolein on both prevention effect of carcinogenesis and anti-inflammatory effect. These result indicated that these two extracts of adlay exhibited inhibitory effect on both tumor and inflammation. In addition, it is also suggested that Monoolein is more effective than Trilinolein.<br>

Phytochemical analysis and anticancer capacity of Shemamruthaa, a herbal formulation against DMBA- induced mammary carcinoma in rats

OBJECTIVE@#To investigate the bioactive constituents of Shemamruthaa (SM), a herbal combination and its therapeutic effects on the mitochondrial functions with reference to lipid peroxidation (LPO), antioxidant status, citric acid cycle enzymes and electron transport chain enzymes in mammary tissues of 7,12-dimethylbenz(a)-anthracene (DMBA) induced mammary carcinoma in rat model.@*METHODS@#Adult female Sprague-Dawley rats were used for the study and were divided into four groups. Group I served as control and Group II rats were induced mammary carcinoma by administration of DMBA (25 mg/kg b.w.) orally. The normal and cancer-induced rats (Group III) were treated with SM (400 mg/kg b.w./day) orally by gastric incubation for 14 days. Group IV rats served as SM-treated control animals.@*RESULTS@#Cancer-induced rats showed a considerably increased level of LPO with concomitant decreased levels of antioxidants, citric acid cycle enzymes, electron transport chain enzymes and cytochrome contents in the mammary tissue. Treatment with SM brought back the aforementioned biochemical parameters to near normal.@*CONCLUSIONS@#From the results, it can be inferred that Shemamruthaa possesses significant anticancer effect through its role in attenuation of LPO, prevention of membrane damage and restoring membrane integrity.
