This study was conducted to determine the degree of heavy metal contaminations in the soils around the perimeter of an industrial park located in the city of Sta. Rosa, Laguna, Philippines that houses light-tomedium scale manufacturing industries, through accumulation of heavy metals in two plant systems viz. Bougainvillea spectabilis (bougainvillea) and Leucaena lecocephala (ipil-ipil). Results of study revealed that the soil samples collected from the study site contained higher concentrations of Cu and Zn compared to a residential site as non-polluted source, some amount of nonessential mineral like Cd and Pb was also found from the sample collected from the study area. Findings of the study suggested that Cu is an immobile element, was highly accumulated in the roots of B. spectabilis, while highest concentration of Zn was accumulated in the leaves. Moreover, the leaves of L. leucocephala collected from the study site accumulated significantly higher concentrations of both Cu and Zn as compared to the leaves of the same plant species collected in a residential site. The non-essential metals, Cd and Pb, exhibit no significant difference in their accumulation and distribution to different plant parts and between the industrial and residential sites.
The study was aimed to determining the knowledge, patterns of use, and attitude towards the use of complementary and alternative medicines (CAM) by herbalists (n=38) and lay people (n=582) from the municipalities of Indang, Maragondon, Amadeo, Magallanes, and Alfonso and the city of Tagaytay, all located in the upland portion of the province of Cavite. Data pertinent to the afore-said aims were gathered through questionnaires and focus group discussions. Nine forms of CAM were documented as used by the interviewees. Leaf extract (decoction) and traditional massage (hilot)was the most prevalent types of CAM across all studied areas, contributing 71% (n= 440) and 54% (n= 335), respectively. Furthermore, their widespread utilization was mainly due to the recommendations from family members (31%, n=192) and doctors (35%, n= 217). Amongst the various ailments associated with the use of CAM, common colds (70%, n= 434), cough (69%, n=428), and fever (61%, n= 378) were the most treated. Overall, a generally positive attitude towards the use of all forms of CAM recorded in this study was shown by most participants in all the surveyed municipalities/city. Therefore, present study concludes that CAM plays a major health care role amongst the interviewees.
This study was conducted to determine the angiogenic effects of different concentrations of phytopigments i.e. phycocyanin from Spirulina platensis and chlorophyll from Chlorella vulgaris on the chorioallantoic membrane (CAM) of developing chick embryo. Findings of study revealed that different concentrations of both crude phytopigments inhibit angiogenesis as shown by the continuous decrease of the vascular density index on the CAM of 10-day old chick embryo. However, Scheffe method showed that only 200 ppm and 300 ppm of crude phycocyanin and all experimental treatments of crude chlorophyll, including the 150 ppm, were able to significantly inhibit angiogenesis.It was also established that there is no significant difference in the angiogenic effects between the two phytopigments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
