| 1 | Biochemical changes in phenols,flavonoids,tannins,vitamin E,β-carotene and antioxidant activity during soaking of three white sorghum varieties显示文摘Objective:To investigate the changes in total phenols,flavonoids,tannins,vitamin E, β-carotene and antioxidant activity during soaking of three white sorghum varieties.Methods: The changes in total phenols,total ilavonoids,tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity during soaking of sorghum grains were determined.Results:Total phenols,total flavonoids,tannins,vitamin E,P-carotene and antioxidant activity in raw sorghum were ranged from 109.21 to 116.70,45.91 to 54.69,1.39 to 21.79 mg/100 g,1.74 to 5.25,0.54 to 1.19 mg/kg and 21.72%to 27.69%and 25.29%to 31.97%,respectively. The above measured compounds were significantly decreased after soaking.p-Hydroxybenzoic acid,vanillic acid,syringic acid and cinnamic acid represent the major phenolic acids in Dorado variety.While ferulic acid,p-coumaric acid,gallic acid and caffeic acid represent the major phenolic acids in Shandaweel-6.On the other hand,protocatechuic acid represents the major phenolic acids in Giza-15.Regarding flavonoids components,Dorado was the highest variety in kampferol and naringenin while Shandaweel-6 was the highest variety in luteolin, apigenin,hypersoid,quercelin and christen.Finally,Giza-15 was the highest variety in catechin. Phenolic acids,flavonoid compounds and antioxidant activities were decreased after soaking. Conclusions:Sorghum varieties have moderate quantities from total phenols,total flavonoids, tannins,phenolic acids compounds,flavonoid components,vitamin E,P-carotene and antioxidant activity which decreased after soaking. | Abd El-Moneim MR Afify Hossam S El-Beltagi Samiha M Abd El-Salam Azza A Omran | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，3： | 7 |
| 2 | Acaricidal activity of different extracts from Syzygium cumini L.Skeels(Pomposia) against Tetranychus urticae Koch显示文摘Objective:To investigate the acaricidal activity of different extracts from Syzygium cumini(S.cumini)(Pomposia)againsst Tetranyckus urticae Koch(71 urticae)and the biochemical changes in antioxidants enzymes.Methods:Six extracts of S.cumini(Pomposia)at concentrations of 75,150 and 300μg/mL were used to control T.urticae(Koch).Results:The ethanol extract showed the most efficient acaricidal activity agent against T.urticae(98.5%)followed by hexane extract(94.0%),ether and ethyl acetate extract(90.0%).The LC_(50)values of the promising extract-were 85.0,101.0,102.0 and 98.0μ/mL,respectively.The activities of enzymes including ascorbate peroxidase(APX),peroxidase(POD),superoxide dismutase(SOD)and catalase(CAT)in susceptible mites were increased.The activities of all antioxidant enzymes reach the maximum value in mites at LC_(50)with ethanol and ethyl acetate extracts,respectively.Conclusions:The extract of S.cumini has acaricidal acivity against T.urticae,and the ethanol extract is the most efficient. | Abd El-Moneim MR Afify Hossam S El-Beltagi Sayed A Fayed Emad A Shalaby | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，5： | 5 |

| 4 | Effect of lead acetate toxicity on experimental male albino rat显示文摘Objective:To evaluate the effect of different doses of lead acetate(1/20,1/40 and 1/60 of LD_(50))on body weight gain,blood picture,plasma prolein profile and the function of liver,kidney and thyroid gland.Methods:Male albino rats were divided into four groups,the first group represented the health control animals,while the second,third and fourth groups were ingested orally with sub lethal doses of load acetate(1/20,1/40 and 1/60)of the oral LD_(50),respectively.One dose was ingested every two days during the experimental period(14 weeks)including the adaptation time.Blood was collected and used for all analysis.Results:The results showed that,the ingestion of Pb^(2+)induced significant stimulation in glutamic-pyruvic transaminase(ALT)and glutamic-oxalacetic transaminease(AST)activity.Also,total soluble protein and albumin contents of plasma were significantly decreased,while the content of globulin was changed by the Pb^(2+)treatments.The cholinesteiase activity was inhibited,but the activities of alkaline and acid phosphates and lactate dehydrogenase were stimulated,while plasma glucose level was elevated as a result of lead acetate intoxication.In case of blood picture,Pb^(2+)ingestion reduced the contents of hemoglobin and RBCs count of intoxicated rat's blood and the plasma levels of T3,T4 and blood WBCs count were decreased.Conclusions:It can be concluded that lead acetate has harmful effect on experimental male albino rats.Therefore,the present work advises people to prevent exposure to the lead compound to avoid injurious hazard risk. | Nabil M Ibrahim Esam A Eweis Hossam S El-Beltagi Yasmin E Abdel-Mobdy | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，1： | 1 |
