Biological and Biochemical Studies on Pollen Grains Date Palm Adding to Rats Diet

The present study was conducted on experimental animals show the effect of different levels (14%, 20%, and 30%) of pollen grains of date palm on food intake, feed efficiency, serum lipid profile, serum glucose, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), serum urea and createnin. Twenty eight male albino rats sprague Dawley strain weighing (95-110g) ten weeks old. They were divided into 4 groups (7 rats each), the rats of the control group were fed on standard diet, and the other 3 groups were fed standard diet plus 14%, 20% and 30% of pollen grains respectively. Food and water were provided ad-libitam for 4 weeks, at the end of experiment blood sample was taken and organs were removed. Serum was separated and kept at -20C° until analysis.The result showed that: • Weight gain was highly significant in group (2) which received 14% pollen grains when compared to the control group. • Higher values of food intake and feed efficiency ratio in group (2) and (3) compared to the control group. • Significant decrease of serum triglyceride and very low density lipoprotein cholesterol (VLDL-c) in all treatment groups when compared to the control group. • Significant decrease of low density lipoprotein cholesterol (LDL-C) in forth group which received 30% of pollen grains and significant increase of high density lipoprotein cholesterol (HDL-C) in the same group when compared to control group. • Significant decrease in serum glucose were among treatments compared to control group. • Significant decrease in AST in group (4). which received 30% of pollen grains, while there was a significant decrease in ALT in all treatment groups when compared to control group. Finally, there was a significant decrease in serum urea in both group 2 and 3 when compared to control group.
