Title Of The Study: Gamma-Oryzanol Prevents Ethanol-Induced Liver Injury By Ameliorating Oxidative Stress And Modulating Apoptosis-Related Protein Expression In Mice / Lijuan Zhu, Siting Xiang, Zhaoping Ou, Chaoyang Ma, Xianglian Yi, Lin Huang, Yurong Ma, Zengenni Liang, Zhihang Yuan, Lixin Wen, Rongfang Li, Jing Wu, Zhuliang Tan, JineYi / Journal Of Functional Foods

From the findings of this study, it was concluded that Gamma Oryzanol protects against liver injury induced by ethanol by improving the antioxidant defence system, ameliorating oxidative stress and regulating apoptosis-related protein expression. It was further suggested that as a feasible antioxidant, Gamma Oryzanol should be thought of as an upcoming functional ingredient for preventing alcoholic liver injury.

Title Of The Study: Potential Gastroprotective Activity Of Rice Bran ( Oryza Sativa L.) Extracted By Ionic Liquid-Microwave-Assisted Extraction Against Ethanol-Induced Acute Gastric Ulcers In Rat Model / Elsa Trinovita, Fadlina Chany Saputri, Abdul Mun’im / Scientia Pharmaceutica

The results of this study showed that Gamma Oryzanol is effective as a gastroprotective therapy sourced from natural ingredients in treating the incidence of gastric acidity and gastric ulcers induced by Alchohol consumption.

Title Of the Study: Study on the efficacy of the combined regimen of nifedipine and oryzanol in the clinical treatment of children with functional abdominal pain Li Jinluan Taishan People’s Hospital, Guangdong Jiangmen 529200)

From the findings of this study, it was concluded that the combination of nifedipine and oryzanol tablet has a more significant clinical effect in the treatment of children with functional abdominal pain, and has a synergistic effect, which is worthy of promotion and application.

Title Of The Study: Effects Of Gamma-Oryzanol On Gastric Lesions And Small Intestinal Propulsive Activity In Mice / Y Ichimaru, M Moriyama, M Ichimaru, Y Gomita / Folia Pharmacologica Japonica

The results of this study indicate that gamma-oryzanol has an antiulcerative action on gastric lesions induced by Conditional emotional stimuli (CES) and REM sleep deprivation, and it has a suppressive action on the facilitation of intestinal propulsion induced by CES.

Title Of The Study: Effects Of Gamma-Oryzanol On The Movements Of Stomach And Ileum In The Dog / T Mizonishi, T Semba / Japanese Journal Of Smooth Muscle Research

The results of this study indicate that gamma-Oryzanol produces the enhancement as well as inhibition of gastric and ileal movements. These effects may be produced by the reaction to the central nervous system of the gastric and ileal movements.

Title Of The Study: Effects Of Gamma-Oryzanol And Atropine On Gastric Secretion Stimulated By Insulin Or 2-Deoxy-D- Glucose / K Mizuta, K Itaya / Folia Pharmacologica Japonica

In this study pretreatment with gamma-oryzanol (100 mg/kg, s.c., once daily x 5) depressed the gastric secretion stimulated by insulin or 2-deoxy-D- glucose. From these results, it is considered that the inhibitory action of gamma-oryzanol on gastric secretion may be due to depression of the vagus system

Title Of The Study: Effects Of Gamma-Oryzanol On Gastric Secretions In Rats / K Mizuta, H Kaneta, K Itaya / Folia Pharmacologica Japonica

The results of this study indicate that the gastric antisecretory effect of gamma-oryzanol is mediated by the vagus nerve which plays a role in the action of gastrin.

Title Of The Study: Studies On Gamma-Oryzanol. III. Influence Of Gamma-Oryzanol On Circadian Rhythms Of Serum Gastrin, 11-OHCS And Gastric Secretion In Rats / K Itaya, J Kiyonaga, M Ishikawa, K Mizuta / Folia Pharmacologica Japonica

In this study pretreatment of rats with gamma- oryzanol 100 mg/kg, s.c., for 5 days tended to decrease serum gastrin levels and gastric secretion and to increase serum 11-OHCS. Suppressive patterns of serum gastrin and gastric secretion following the pretreatment with gamma-oryzanol corresponded to the circadian rhythms in the antiulcerogenic action of gamma-oryzanol.

Title Of The Study: Studies Of Gamma-Oryzanol. (2) The Antiulcerogenic Action / K Itaya, J Kitonaga, M Ishikawa / Folia Pharmacologica Japonica

In this study an 8-day treatment with gamma-oryzanol, 100 mg/kg, s.c., showed significant inhibition of fasting ulcer, while the 5-day pretreatment exerted slight effects on ulcers by pylorus-ligation or stress-atropine. A 10-day treatment with the same dose of gamma-oryzanol in acetic acid ulcers lowered the serum level of gastrin. It is suggested that the monoaminergic neuron system is involved in the anti-ulcer action of gamma- oryzanol.

Title Of The Study: Studies Of Gamma-Oryzanol (1). Effects On Stress- Induced Ulcer / K Itaya, J Kiyonaga / Folia Pharmacologica Japonica

The results of this study indicate that the antiulcerogenic action of gamma-oryzanol is due to the participation of the autonomic nervous system, but not the hypophyseoadrenal axis.
