Metal oxides are widely used in adsorption technology as adsorbent surfaces because of their efficiency, low cost and unique physical properties. The aim of this review to clarify the role of aluminium oxide and Nano aluminium oxide in removing some chemicals contain that influence on human health such as dyes, antibiotics, and heavy metals. This paper also includes the affective of some adsorption parameters like pH, contact time, removal percentageand temperature. The Adsorption nature, kinetic adsorption models and isotherm models are also reported here.

Background: Ginseng is a medicinal herb that has been used in many laboratory experiments because of its pharmacological activities of its some constituents including ginsenosides, phytosterols, sesquiterpenes, flavonoids, polyacetylenes, alkaloids, and phenolic compounds. This herb has been used in many European and Middle Eastern countries as a traditional remedy for several diseases due to its antithrombotic, antioxidative, anti-inflammatory, and anticancer effects. So we designed this study to detect the effect of various concentrations of ginseng herp on the catalytic activity of monoaminoxidase (MAO) and peroxidase through in vivo and in vitro study. Methods: The in vivo study included the effect of Ginseng extract on the catalytic activity of MAO. Eighteen female mice were collected and distributed to three groups. The first group consist of six mice was not treated with ginseng extract (control group).Each of second and third groups consisted of six mice that were orally injected with 250 mg/kg and 450 mg/kg of body weight of ginseng extract respectively during fourteen consecutive days. The activity of MAO was calorimetrically measured at 272nm in the isolated brain mitochondrial fractions. The in vitro study of ginseng extract was calorimetrically tested in human serum of both MAO and peroxidase enzymes at 272nm, 510 nm respectively through two experiments; the first experiment includes measuring the activity of the enzymes using different concentrations of ginseng extract. The second experiment consisted of measuring the activity of the enzyme using different concentrations of substrate and constant concentration of ginseng extract. Results: Through in vivo and in vitro study, the outcomes manifested that ginseng extract is good inhibitor towards MAO and peroxidase enzymes. The results also revealed that the inhibition capacity of ginseng extract increased with growing its concentration. Where higher percentage of inhibition at highest concentration of ginseng extract (0.1 mg\mL) was 83.26% and 64.6% for MAO and peroxidase respectively. The inhibition Kinetic characteristics of ginseng extract were Vmax= 20 µmol\min\L,Ki=0.03 for MAO and Vamx =83.3 µmol\min\L , Ki= 0.003 (mol\L) for peroxidase, this results refer that ginseng extract is competitive inhibitor with MAO while is un competitive inhibitor with peroxidase. Conclusion: The results of this study revealed that the inhibitory capacity of ginseng extract towards both MAO and peroxidase. The inhibitory of properties of ginseng extract opens up new horizons towards the medicinal uses of this herb.

Many other researchers studied the effect of many part from Artemisia but not fruit on the diabetes. Artemisia fruits were used in this study, they had been dried and grinded then some chemical analyses were done to determine the active compounds of the fruits in both hot and cold extract. Since our results shows that the hot extract has more active compounds from the cold, the hot extract of Artemisia L. fruit were used in this study to determine the efficacy of it as diabetic treatment in streptozotocin-induced diabetic mice. Streptozocin (STZ) was used to induce diabetes in 35 mice which divided to 5 groups. One group consumed normal saline while the other four consumed Artemisia with four different concentrations. Another 10 mice weren't injected with STZ which were they had been divided to two groups; one consumed Artemisia and the other consumed normal saline. The fasting blood sugar (FBS) was determined on different period; zero time, 7 and 14 days after treatment. The mice were scarified and blood was collected. Insulin, GOT and GPT levels were determine in serum. FBS was higher in all STZ-induced diabetic mice dropped to normal after 14 days. The FBS of mice, treated with 500 Artemisia/ kg mice, was closer to control. Insulin level was lower in STZ-induce diabetic mice without treatment raised to normal after treatment with 500 and 1000 mg Artemisia/ kg mice. Same results were found for GOT and GPT levels. As conclusion, Artemisia appears to be a good modulator for diabetes especially at 500 and 1000 mg Artemisia/ kg body weight.
