RESUMO
A new plant milk was discovered from the seed of Adenanthera pavonina. The physicochemical and nutritional properties of the new pro-milk extract were assessed, and their biochemical effects were compared with those of soy bean extracts. Eleven groups of three albino rats each were used to assess the health benefits of the pro-milk. Groups were separately administered 3.1, 6.1, and 9.2 µl/g animal wt. pro-milk extract from A. pavonina seed, 6.1 µl/g animal wt. milk extract from soybean, and 6.1 µl/g animal wt. normal saline for 7 or 14 days. The "baseline" group consisted of those sacrificed on day 0. Among the physical properties considered, the pro-milk from A. pavonina had significantly higher (P < 0.05) hue color value and significantly lower (P < 0.05) L* than that from soy bean did. The pro-milk from A. pavonina had a significantly higher (P < 0.05) level of protein (36.14 ± 0.12%), Ca (440.99 ± 0.93 mg/l), Mg (96.69 ± 0.03 mg/l), K (190.41 ± 0.11 mg/l), Na (64.24 ± 0.24 mg/l), and Cu (0.55 ± 0.24 mg/l), and a significantly lower (P < 0.05) level of Mn (0.04 ± 0.01 mg/l) and vitamins A (undetectable), C (1.87 ± 0.01 mg/100 g), and E (0.12 ± 0.01 mg/100 g) compared to those of soy milk. The daily consumption of the pro-milk extract from A. pavonina for 14 days significantly reduced (P < 0.05) Ca2+-adenosine triphosphate synthase (Ca2+-ATPase) at low dose (3.1 µl/g animal wt.), but significantly increased (P < 0.05) Mg2+-ATPase at high dose (9.2 µl/g animal wt.). Daily administration of the A. pavonina extract for 14 days caused a significant reduction (P < 0.05) in acetylcholinesterase activity in the liver, intestine, heart, and kidney, suggesting that the pro-milk may facilitate ions transportation across the membrane. The pro-milk offers promising beneficial effects for patients with neurological diseases, as well as supporting general health owing to the high protein and mineral content. Vitamins fortification is recommended during production.
RESUMO
Sorghum bicolor grains are rich in phytochemicals known to considerably impact human health. Several health-promoting products such as flour, staple food, and beverages have been produced from sorghum grains. This study investigated the protective and modulatory effects of a sorghum diet on the genes of some antioxidant and glycolytic enzymes in alloxan-induced diabetic rats. The rats were randomly distributed into six groups: the control group received normal diet, while the other groups were pretreated with 12.5, 25, 50, 75, and 100% of the sorghum diets daily for 8 weeks before the administration of a dose of alloxan (100 mg/kg BW), after which blood was collected and the liver was excised. The effects of the diets on blood glucose levels, liver dysfunction indices, and markers of oxidative stress were assessed spectrophotometrically, while the gene expressions of key glycolytic enzymes and enzymatic antioxidants were assayed using reverse transcriptase polymerase chain reaction. It was observed that the pretreatment of the experimental animals with the diets normalized the blood glucose before and after the administration of alloxan. The sorghum-treated groups also showed statistically significant (p < 0.05) decrease in liver dysfunction indices and markers of oxidative damage compared with the control. In addition, statistically the diets significantly decreased (p < 0.05) the relative expression of superoxide dismutase, glutathione peroxidase, glucokinase, phosphofructokinase, and hexokinase genes in the experimental animals compared with the control. Overall, this study showed that the preadministration of fermented sorghum diet significantly protected against hyperglycemia and suppressed glucose utilization via glycolysis in the liver of alloxan-induced diabetic rats. Thus, the consumption of sorghum diet may protect against hyperglycemia and oxidative damage and may therefore serve as functional food for management of diabetic mellitus.
