Rafidain Journal of Science, Volume 18, Issue 4, Pages 1-7

This study was conducted to investigate the effect of olive leaves on carbohydrate metabolism in male rabbits (8-10 weeks old). The animals were divided into 3 groups of six a animals each. The first and second groups were treated daily for 10 weeks with olive leaves (2.5 with ration) and with olive leaves boiled extract ( 2500 mg/kg B.wt orally)respectively. The third group served as control. The results showed alterations in carbohydrate metabolism as manifested by the significant decrease in blood glucose levels and the accompanied changes in the chemical composition of liver as represented by the significant increase in the percentage of carbohydrate in the treated groups and protein in the groups treated with olive leaves in ration and in the thigh as represented by the significant increase in the percentage of protein in the treated groups and fat and carbohydrate in the groups treated with olive leaves with ration. The results also showed significant increase in the mean body weigh increment and feed efficiency in the group treated with olive leaves with vation.

Rafidain Journal of Science, Volume 18, Issue 4, Pages 72-87

One proteinous component had been isolated from gel filtration chromatograghy of the full saturated precipitate produced by ammonium sulphate of the aqueous extract of the Cinnamomum cassia bark. The apparent molecular weight of the isolated component was found to be (6558) Dalton using gel filtration chromatograghy and (6732) Dalton using sodium dodecyl sulphate polyacryl amide gel electrophoresis. The results showed that the cold crude aqueous extract non- proteinous extract and proteinous component isolated from aqueous extract were lowered glucose level using a dose of 100 mg/kg weight. The percent decrease were (38%, 21% and 25%) respectively in normal mice, where as in diabetic mice, the proteinous component isolated from aqueous extract was the most effective in lowering glucose level using a dose of 100 mg/kg body weight where the percent decrease was 85%. Finally, the crude aqueous extract and proteinous component isolated from the cold aqueous extract showed a significant decrease in the level of total cholesterol (TC), triglyceride (TG), very low density lipoprotein (VLDL-C) and low density lipoprotein (LDL-C) in normal mice. However, in diabetic mice, the cold non- proteinous extract was the most effective in lowering TC, TG, VLDL-C, LDL-C and HDL-C levels.

Rafidain Journal of Science, Volume 18, Issue 4, Pages 88-101

In this work, thermal stability of epoxy resin blended with polyurea- metal complexes were investigated using (TGA) and compared with the non- blended polyurea complexes. It was found that the polyureas alone exhibit thermal stability between 250-310 ْ C. The values of IDT decreased in the order PBU>POU> PPU>PTU, while the values of MDT is much closer to each other in the rang 335- 350 ْ C. The differences between TGA thermograms appeared in polyurea complexes were approximately diminished in epoxy blend thermograms especially in the region 300-500ْ C. The complete decomposition temperature for the blends are more than 600ْ C whilest, this temperature not exceeds 400 ْ C for epoxy resin alone. The average reference values IDT, MDT and (W%) 350 are 118ْ C, 386ْ C and 62% respectively for the untreated samples and raised to 180ْ C , 590 ْ C and 86% respectively for (alkaline or acidic ) treated blends.

The research included a biochemical study of lipid peroxidation and other antioxidants and their relation with Diabetes Mellitus ( D.M.) type I (50 patients) and type II (100 patients). Measurement of some biochemical parameters were performed.
The results of statistical analysis showed a significant increase of malondialdehyde peroxy nitrite radical and superoxide dismutase activity in serum of patients with type II when compared with normal. A significant decrease was also observed in concentration of vitamin C, vitamin E, glutathione, selenium, ceruloplasmine, uric acid and zinc in serum of diabetic patients of both types and peroxy nitrite radical in type I only.
Other factors such as age, duration of the disease states, glucose concentration on lipid peroxidation and other antioxidants concentration were also performed. The results predicated that there was a significant increase in malondialdehyde with age in both types of diabetes and a significant decrease in serum concentration of vitamin C and E, glutathione with age in type II. A significant increase in MDA concentration with a decrease in vitamin C were also found in patients with increasing the duration of disease and a significant increase in malondialdehyde concentration with increasing blood glucose concentration, while there was a significant decrease in vitamin C and E concentrations.
