In the present study soap chamber test was carried out for assessing irritancy of toilet soaps and soap ingredients. The results obtained in the present study are summarized as follows; This chamber test can discriminate the differences of irritancies between various soaps and soap ingredients. 2. Soap irritancy is not directly related with its alkalinity. 3, Erythema score and scaling score tend to parallel each other with weak correlation(r=p 46), but erythema score and fissuring score show strong correlation (r=p77) Scaling score and fissuring score show moderate correlation(r=p.64), 4. In the eighteen kinds of toilet soaps, two soaps are most irritating, harsh soap and the total irritancy scores of all soaps are within 1. 9 5. 1. Baby soaps are not milder than the common toilet soaps. 5. Generally, total irritancy score of soap ingredients is concentration dependent. Average total irritancy scores of five main soap ingredients in 4 times of recommended allergen concentration are as follows; Builders 5. 30, Perfumes l. 88, Color 0. 70, Fatty acids p. 35 and Superfat p.

Saturated fatty acids increase LDL - cholesterol (bad cholesterol) and total cholesterol. The olive, corn, soybean oils and fish fat, duck fat are good for health. The pig, chicken fat and butter should be moderately eaten. It should be consumed fairly fish fat and vegetable oil in order to regulate the omega 6 and omega 3.

3.Serum fatty acids composition of inhabitants in some districts of Ha Noi and HCM city.
Journal of Preventive Medicine 2002;12(1):41-47
The population under study was selected from Cua Dong, Thanh Luong precinct and Yen So commune (Ha Noi city) and Ben Thanh, Nha Be and Can Gio (Ho Chi Minh city); with the total of 594 subjects (200 from rural areas, 196 from suburbs and 198 persons from urban areas). The results: the total value of serum fatty acid varied from 2719 +/- 935 to 4174 +/- 1421 g/ml: out of which the lowest values were observed in rural population and the highest ones were among HaNoi inhabitants. It was also found that in both surveyed areas, the percentage of monounsaturated fatty acid was remarkably higher in rural areas. However, inversely the percentage of polyunsaturated fatty acid was higher among urban population.

4.The relationship between dietary fat and cardiovascular disease
Journal of Preventive Medicine 2001;11(4):62-70
Saturated fatty acid with 12-16 carbon and trans- monounsaturated fatty acid (MUFA) have stimulating effects while polyunsaturated fatty acid (PUFA) and cis-MUFA have inhibiting effects on atherogenesis. Besides, n-3 PUFA shows its effective antithrombogenesis. For the prevention of cardiovascular disease in Vietnamese people, the indices of atherogenesis and thrombogenesis, as well as the n-6/n-3 ratio of Vietnamese diet had better to be recommended to reduce by higher consumption of fishes, vegetable oils rich in n-3, algae and plankton.

OBJECTIVES
Carica papaya has been widely used commercially for skin care due to its therapeutic benefits. The potential of its flower to promote hair growth has been traditionally recognized in other countries but not in the Philippines. In this study, we explored the effect of various extracts of C. papaya flower in the biological activities associated with hair loss, including 5α-reductase inhibition and antioxidation, as well as identified the putative compounds present in the most potent extract.
METHODSThe flowers of C. papaya were macerated separately with ethanol, ethyl acetate, and hexane to obtain their corresponding crude extracts. These extracts were subjected to antioxidant tests via 2,2′-diphenyl-1-picrylhydrazyl (DPPH), and ferric-reducing antioxidant power (FRAP) assays. The total phenolic and flavonoid contents (TPC and TFC) of the crude extracts were determined, as well as the ability of the extracts to inhibit 5α-reductase. The compounds present in the most potent extract were determined using ultraperformance liquid chromatography quadrupole time of flight mass spectrometer (UPLC/MS-QToF).
RESULTSEthyl acetate extract displayed significantly higher DPPH activity (0.001755 ± 0.00092 ascorbic acid equivalent antioxidant capacity) and 5α-reductase inhibitory activity (115.18 ± 11.61 mg dutasteride/g) compared to ethanol (DPPH: p=0.0121; 5α-reductase: p=0.0016) and hexane (DPPH: p=0.0038; 5α-reductase: p < 0.0001) extracts. Similarly, ethyl acetate extract gave the highest FRAP (0.4842 ± 0.0936 mg ascorbic acid/g) activity, TFC (0.0403 mg quercetin/g), and TPC (0.0463 mg gallic acid/g) among the extracts. Forty-nine compounds were annotated in the ethyl acetate extract, with seven (7) putatively identified as fatty acids (9-hydroxy-10,12-pentadecadienoic acid, 9,12,15-octadecatrienoic acid), hydroxyflavone (5-methylkaempferol), alkaloid (allomatrine), dipeptide derivative (aurantiamide acetate), bufotalinin, and 6β-acetoxy-5-epilimonin based on the Traditional Chinese Medicine Library.
CONCLUSIONThese results suggest that local C. papaya flowers can be a source of hair growth-promoting agents via their antioxidant and 5α-reductase inhibitory potential.

7.Lipid content and fatty acid compostion in breast-milk of Vietnamese lactating women living in red river delta
Journal of Medical Research 2003;24(4):69-74
Lipid concentration and 38 fatty acids in breast milk of Vietnam lactating women living in Red River Delta were determined by gas chroma to graphy. The results of study could be use as reference for Vietnam breast-milk composition that has not yet published in “Table of nutritive composition of Vietnam food”, which is applied to calculate the food consumption of Vietnam infant. The results showed also the variable contents of lipids and fatty acids of various individuals and communities concerning the quantity and quality of lipid dietary intake. Several essential unsatured fatty acids (C18:1 oleic acid, C18:2 linolenic acid, C18:3 linolenic acid) existed in quite high level in Vietnam’s breast milk.

The oil content and fatty acid composition of Ganoderma lucidum collected from different producing areas, varieties, tissue types and growth periods were measured and analyzed. The results showed that the oil content was 23. 61%-34.17% in different domestic producing areas of China; the oil content of fruiting bodies from major varieties cultured in Zhejiang province were 0.81%-1.87%, wall-unbroken spores were 0.07%-0.24%, wall-broken spores were 27.54%-34.17%, so the oil content of wall-unbroken spores were much higher than fruiting bodies, and wall-breaking treatment would increase the oil extraction rate 150-340 times. G. lucidum spores oil was mainly composed of unsaturated fatty acid composition. oleic acid and linoleic content were 53.26%-58.16% and 10.69%-16.87% respectively. Fatty acid composition ratio of spores and fruiting bodies were significantly different by PLS-DA. Determining the composition of fatty acid, especially the content of oleic acid, stearic acid and palmitic acid, could identify the tissue types of G. lucidum products' sources. In addition, the study result showed that the spores and fruiting bodies collected in the first year contained richer oil and fatty acid than second year's samples from the same variety of G. lucidum.

Westernization of lifestyles among Japanese, in particular among young generations, is a matter of concern for future increase in coronary heart disease. We surveyed a total of 349 male university students to examine changes in lifestyles and coronary risk factors in campus life. We compared dietary habits and serum fatty acid compositions as well as other coronary risk characteristics between freshmen (n=171) and fourth-year (senior) students (n=178). Serum fatty acid compositions and dietary intakes of selected foods as well as serum lipids, blood pressures and physical characteristics were examined at the 1996 and 1997 annual health examinations. Compared to freshmen, senior students had a lower frequency of fish, vegetable, milk and egg intake, and a higher frequency of oil and fat intake. The proportions of serum saturated and monounsaturated fatty acids were significantly higher among senior students than among freshmen, whereas the proportion of serum polyunsaturated fatty acids was significantly lower among senior students than among freshmen. Senior students also had higher systolic and diastolic blood pressures, percent body fat, smoking rate and alcohol usage than freshmen. Mean body weight and mean body mass index were not different between the two groups. Senior students generally showed Westernized dietary habits and higher coronary risk profiles than freshmen as indicated by the change of serum fatty acid compositions. Modification of these dietary habits and lifestyles may be important for the prevention of future CHD among Japanese young adults.
