Judul: Konsumsi Minyak Sawit Mentah Meningkatkan Kadar Protein CD4 dan CD8 Limfosit Ibu Usia Produktif di Desa Dramaga dan Babakan,Kecamatan Dramaga Bogor
Abstrak: Vitamin A deficiency is one of the most serious health problem in Indonesia. Crude palm oil (CPO) contains high carotenoid, such as β–carotene, as a source of provitamin A. However, its use in Indonesia does not exist. Socialization and distribution can increase application of CPO. Palm oil has been reported to improve health. β–carotene as a provitamin A can modulate immune functions, enhance cell proliferation and play role as an anticancer. CD4 is a marker protein on T helper (Th) cells while CD8 is a marker protein on T cytotoxic (Tc) cells. Increasing level of CD4 and CD8 protein is expected to increase immune responses. 70 respondents were given CPO freely for 2 months with one bottle of CPO containing 140 ml per week and then lymphocyte from 16 healthy housewife respondents were analyzed by using Bradford and ELISA method. Respondents acceptance to CPO was observed. Lymphocyte analyzed showed that most of respondents had increasing level of CD4 protein from 0.095 to 0.117 and CD8 protein from 0.078 to 0.079. This research shows that CPO consumption can increase the level of CD4 and CD8 proteins and also can be used as an alternative source of provitamin A for tackling vitamin A deficiency problem. In addition, respondents can accept CPO as a new product very well because it can increase respondents’s health.

Judul: Effect of Crude Palm Oil Consumption on the Level of Plasma Beta-Carotene, Malondialdehyde and Xanthine Oxidase Activity of Blood Plasma and Product Acceptance by Low-Income Respondents at Dramaga and Babakan Village, District of Bogor
Abstrak: Crude palm oil (CPO) is obtained from mesocarp extraction of palm fruit (Elaesis guineensis Jacq). CPO contains beta carotene around 400 – 1000 ppm. Beta carotene from CPO has some biological activities, such as vitamin A activity, protecting from UV rays, regulating immune function, controlling cell proliferation, and antioxidant activity. As an antioxidant, CPO can inhibit free radicals that cause lipid peroxidation, or anion superoxide production mediated by xanthine oxidase system. This research was a case study on SawitA program, that aimed to identify respondent acceptance of CPO as natural source of vitamin A. This research was intended to evaluate the effect of CPO consumption on the level of beta-carotene, malondialdehyde and xanthine oxidase activity in blood plasma. This study implicated 78 low-income respondents that were given about 140 ml CPO/week for 2 months, freely. Plasma blood from 22 healthy housewives respondents were analysed before and after consuming CPO. This study showed that daily consumption of approximately 2,94 ml CPO increased the level of plasma beta carotene from 1,907±1,006 to 1,965±0,762 μmol/l, reduced the level of malondialdehyde from 0,482±0,237 to 0,408±0,19 nmol/ml, but did not effect xanthine oxidase activity significantly. In addition, low-income respondents can accept CPO as a new product very well as part of their daily cooking oil.
