TL;DR: Results showed that weekly cumulative food intake but not body weight were lower in RBO-treated rats during 1st to 5th week of treatment, which were normalized at the end of treatment.
Abstract: Rice bran oil (RBO) is an important product of rice bran. It is considered to be one of the most important nutritious oil due to its favorable fatty acid composition and unique composition of naturally occurring biologically active antioxidant compounds. This study was designed to monitor the effects of oral intake of RBO on stress response in rats. RBO was extracted using hexane. Rats were divided into Control and test (RBO-treated). RBO-treated rats were given 0.2 ml/day RBO for 6 weeks. Food intake and body weight changes were monitored weekly. After 6 weeks open field activity and Morris Water Maze (MWM) test were performed. Results showed that weekly cumulative food intake but not body weight were lower in RBO-treated rats during 1st to 5th week of treatment, which were normalized at the end of treatment. Exploratory activity of RBO-treated rats in an open field was increased. Spatial memory in Morris water maze was enhanced in RBO-treated than control rats. An episode of 2 h restraint stress decreased the 24 h food intake of both control and RBO-treated animals. Behavioral deficits were lower in RBO-treated rats. Exposure of 2 h restraint stress increased brain serotonin (5-hydroxytryptamine: 5-HT) metabolism. These increases were lower in RBO-treated restrained than their respective control animals. Serotonergic neurotransmitter mechanism is implicated in stress. The findings of the study show beneficial effects of RBO in learning and memory functions. Moreover, the study also highlights the attenuating effect of RBO on stress induced behavioral and neurochemical effects in rats.

TL;DR: Two ω3/Δ15 fatty acid desaturase genes cloned from rice and soybean into rice under the control of an embryo-specific promoter, REG, introduced a trait of high ALA content that was stably inherited.
Abstract: Rice bran, the byproduct of brown rice, with a million tons produced annually, is the major storage organ for lipids. Increasing the α-linolenic acid (ALA) content in rice bran by biotechnology strategies is beneficial for both human health and the oil industries. We introduced two ω3/Δ15 fatty acid desaturase genes cloned from rice and soybean into rice under the control of an embryo-specific promoter, REG. The ALA content (dry weight) in embryos and bran was increased up to 6.09 and 5.86 mg/g, respectively, in transgenic lines, which was 25.4- and 27.9-fold higher than the 0.24 and 0.21 mg/g in the nontransformant control. ALA accounted for 46.7 and 44.3 % of the total fatty acids in embryos and bran, respectively, of transgenic plants, which was comparable to that in linseed and perilla seeds. The trait of high ALA content was stably inherited. The enhanced ALA content was preferentially located at the sn-2 position in triacylglycerols, which are digestible and absorbable for humans. ALA-enriched rice bran may help alleviate human health problems caused by ALA deficiency, with the production of healthy bran oil for humans and feed for animals.
