The fungus Rhizoctonia solani was isolated from rice, this fungus causes many diseases for plant and crops damage. To control this fungus by a safe method without causing any damage to environment, animal and human, we prefer using the alcoholic extract of some plants. The effect of alcoholic extract for leaves of Cassia spp., Salvia officinalis and Achillea millefolium was tested by using four concentrations for each extract 5,10,15,20 mg /ml these results were compared with antifungal Trichoderma harzianum and Trichoderma viride and it was noticed that these extracts have a high inhibiting effect against this fungus. The percentage of inhibition was 100% for all extracts and all concentrations that used in this study except the concentration 5 mg / ml of alcoholic extract for the leaf of Cassia spp. the percentage of inhibition was 90.3%. This proves that the alcoholic extract of the leaves has a high ability for inhibition similar to the biocontrol agent that was used.

The percentage of milk samples exceeding the permissible limits 100% of lead and copper in buffalos' milk and lead in cows' milk and 83.3% for lead in ewes' milk and for copper in cows, goats and ewes' milk and 66.6% for lead in goats milk. The results showed that the mean concentration of lead and copper 0.524 and 0.824, 0.127 and 0.958, 0.323 and 0.375, 1.402 and 0.462 mg/kg in the adult dried powder, infant, pasteurized and condensed milk, respectively. Milk samples which exceed the permissible limits of lead 100% in adult dried, pasteurized and condensed milk and for copper in the infant and adult dried powder milk and 83.3% for lead in the infant milk and 33.3%, 16.6% for copper in pasteurized and condensed milk. The findings showed no significant differences in the mean concentration rates of lead and copper among all types of raw milk in study. However, there was a significant difference in the mean concentration levels of copper between adult and infant milk from pasteurized and condensed milk.

The electrochemical behavior of Eriochrome Red B (ERB) using square wave voltammetry (SWV) with three electrodes cell was studied. The cell consists of working electrodes, either graphite electrode (GE) or Poly ERB-graphite electrode (poly ERB – GE), auxiliary electrode (2mm pt wire) and reference electrode (Ag/AgCl . sat.KCl).
The ERB gives two reduction peaks at GE and Poly ERB- GE, one at -0.194 V, second at 0.068 V for GE and at -0.561V, 0.203 V for Poly ERB-GE.
The effect of pH on the reduction peaks of ERB at the two electrodes (GE and poly ERB-GE ) was studied.

The research includes a clinical study of adiponectin hormone and its relation with cardiovascular diseases. The normal value of adiponectin hormon level in human serum was found to be (9.79± 0.91 ug/ml) in control group for both sexes at age (35-70 year). The study also showed a significant decrease in adiponectin hormone level (6.12 ±1.01 ug/ml(in serum of cardiovascular patients group for both sexes at (39 -75 year) in comparison to control.
The results also indicated a significant increase in the level of insulin hormone, glucose, insulin resistance (HOMA-IR), concentration of total cholesterol, triglyceride, low density lipoprotein -cholesterol, very low density lipoprotein –cholesterol, the risk factor ratio (total Cholesterol/ HDL), total lipid, malonaldehyde (MAD), the activity of Peroxidase, GOT and ALP in patients group. While a significant decrease in concentration of high density lipoprotein – cholesterol, glutathione also the activity of glutathione –S- transfers, glutathione peroxidase, arylesterase and catalase in patients group was found in comparison to control.
The relationship between adiponectin hormone and some clinical variables were examined in control and patients. The results showed that there were a significant positive correlation between adiponectin hormone and concenteration of high density lipoprotein – cholesterol (HDL- C), the activity of glutathione peroxidase and arylesterase in control group and patients. The results also showed that there was a significant reverse correlation between adiponectin hormone and level of insulin hormone, glucose, insulin resistance (HOMA-IR), concenteration of total cholesterol, triglyceride, (total Cholesterol/ HDL), total lipid, malonaldehyde (MAD) and the activity of GOT and ALP in control group and patients.
It is concluded that the low level of the hormone adiponectin Index is a serious risk of cardiovascular disease and plays an important role in regulating the level of the hormone insulin, insulin resistance and its glucose, which refers to the relationship of diabetes. It also shows a role in regulating the level of lipids and the relationship with oxidative stress processes.
