For example, sol-gel immobilised bioactive liquids such as cineol, camphor, menthol, evening primrose and perilla oil used to functionalise textiles afford either skin-friendly textiles with antimicrobial and antiallergic effects due to immobilised natural oils or textiles for therapeutic treatment of the respiratory tract by means of immobilised mixtures of high volatility natural agents such as eucalyptol, camphor and menthol.27... 

Kim, E.M., Choi, J.H. and Chee, K.M. (1997) Effects of dietary safflower and perilla oils on fatty acid composition in egg yolk. Korean Journal of Animal Science 39,135-144. 

Wilson et al. (39) isolated the toxin, perilla ketone, which causes pulmonary edema (fluid in the lung cavity) in many animal species, although not in pigs and dogs (40). In Japan, 20-50% of long-term workers in the perilla industry developed dermatitis on their hands because of contact with perillaldehyde (41). Small amounts of these components have been detected in perilla oil where it works as an efficient antioxidant. 

The seed of perilla contains 31-51% of oil, which is similar in composition to flaxseed oil, with a higher contribution of PUFA of over 70% (Table 4). The oil is highly unsaturated, with an iodine value of 192-208-g iodine /100-g oil (Table 4). Perilla oil contains over 60% linolenic acid with equal amounts of both linoleic and oleic acids (Table 4). Specific gravity of this oil is higher than flax oil because of a higher contribution of PUFA. Other physical parameters of this oil reflect the composition of its fatty acids. 

The amount of tocopherols in perilla oil is higher compared with flax oil, and a similar contribution of gamma-tocopherol, above 90%, was observed (Table 4). Shin and Kim (49) analyzed perilla oil for lipid composition and established that it contained more than 90% triacylglycerols, 4% glycolipids, and 2% of each phospholipids and sterol esters. 

Perilla oil has been used as a drying oil in paints, varnishes, linoleum, printing ink, lacquers, and for protective waterproof coatings on cloth. It has also been used for cooking and as fuel (56). The meal produced after oil extraction is often used as an animal feed ingredient. 

Composition and content of tocopherols in camelina oil was similar to perilla oil, where more than 80% of all tocopherols were gamma isomer (Table 4). Alpha and delta tocopherols were detected as minor antioxidants (77). The total content of tocopherols was comparable with perilla oil, and higher than that in flax oil (Tables 4 and 2). The total content of tocopherols in camelina oil is higher than canola, flax, soybean, and sunflower.

Female rats were fed a semipurified diet supplemented with safflower oil or perilla oil (from seeds of the beefsteak plant, Perillafrutescens), mated at 11 wk of age, and the male progeny (F i) were weaned at 3 wk of age to the diet of the dam. These diets brought about... 

Both R" and R responses increased in a similar manner during the initial several days. Then, R+ responses kept increasing up to approx 25 d, whereas R responses reached plateau levels in about 10 d, and thenbeganto decrease. The difference in the R responses between the perilla-oil group and the safflower-oil group was usually not significant in contrast, major significant differences were observed in the R response of the two... 

Fig. 3. Brightness-discrimination learning behavior of rats fed an ALA-restricted safflower-oil diet or ALA-sufficient perilla-oil diet over two generations. Lever-pressing responses under a bright light were reinforced with diet pellets (R ), but no pellets were deli vcred on response under a dim light (RT) in the original schedule. Similar results were obtained in the rat strains of Wistar/ Kyoto, SHR, SD, and Donryu rats.

Then, we tried to estimate the efficacy of DHA (ethyl ester) on the reversibility of learning behavior. Unexpectedly, a mixture of DHA and safflower oil (1.6 en% DHA and 4.7 en% LA, Saf-DHA) failed to restore learning ability when the safflower-oil diet was shifted to the Saf-DHA diet after weaning (Table 2) (Ikemoto, A., Ph.D. Thesis, Nagoya City University, 2000). Brain DHA level of the Saf-DHA group was restored to the level of the group fed the perilla-oil diet (4.9 en% ALA and 1.2 en% LA). However, the brain... 

As reported by Benolken (1973), the amplitudes of both the a and b-waves of an electroretinogram decreased significantly as aresultof ALA deficiency in rat (Watanabe, 1987). A diet supplemented with soybean oil (1.5 en% as ALA) did not give maximum amplitudes similar to those observed in the perilla-oil group (Fig. 4). 

Fig. 4. Amplitudes of a- and b-waves in the electroretinogram in rats fed a semipurified diet supplemented with safflower oil or perilla oil, or a conventional diet supplemented with soybean oil. The intensity of the dim light corresponded to 3 in the abscissa, and that of the bright light was 1000 times higher.
