Results showed the treatment fungus Trichoderma sp. has a clear role in increasing the percentage of absorption of copper and zinc in terms of the rate of absorption in leaves and roots, of the of plants grown in soils is treated with fungus compared with plants grown in soils is the non-treated of the fungus, as amended registered 40.4333, 25.309, 49.865, 60.719, 31.0375, 22.250, 41.790, 54.338 mg/l respectively.

The study aimed to determine the statistical distribution of blood group, beside the studying of genotypic frequencies and allelic frequencies in various samples. Three hunderds and eighteen individuals are used as sample representative of patients with Chronic Diseases, 142 patients with Hypertension, 176 patients with Diabetes Mellitus. The results revealed that O blood group higher followed by B then A and finally AB blood group. The results also showed overcome the positive pattern of Rh+ in comparison with the negative pattern of Rh- in all samples. Allelic frequencies calculation of blood groups for these systems were showed the highest frequency was allele i followed by allele IB and allele IA for the ABO system in the three samples, And the allele dominant D showed common on the recessive allele d in all the samples studied.There is strong evidence to suggest that there is an association between ABO blood groups and certain diseases, Therefore this study investigated the possible association of Type 2 Diabetes mellitus and Hypertension with ABO type. The data were derived from 318 patient included 142 subjects hypertension, And 167 subjects had diabetes mellitus attending health centers and laboratories in Baghdad. The statistical analysis showed that there is a high significance differences and that the blood groups as possible to be an early indicator to have Hypertension and Type 2 Diabetes Mellitus. And blood groups were compared to determined the relationship of each group with the disease, Statistical analysis showed that the O blood group have a greater risk with the disease when compared with the other groups. There is a possibility equal to the injury of the disease in people with two blood groups A and B, While the AB blood group have little chance when compared with the rest of groups, This is in the case of Hypertension. As in the case of Type 2 Diabetes Mellitus, The statistical analysis showed that there is a possibility equal to the injury of the disease in people with two O and B blood groups, Followed by people with A blood group, And the likelihood of injury in people with blood group AB was the least comparing to the other group

In recent decades, observed focus largely on the preparation of nano metallic elements, including the gold because of its unique properties and many applications. In most of these researches, the Turkevich' method has been adopted. This method is based on the reduction of gold ion Au3+ to the nano gold Au0 by the addition of a reducing agent to the gold salt H[AuCl4].3H2O. In this research, a novel simple and cost-effective technique is enhanced via the addition of the gold ion (Au3+) to the decreasing agent in opposite to the previous method. This is the cause to call it "The inverse method". In this inverse method one can control the amount of gold salt solution that add and stop this addition by observing the formation of the red color, which indicates the formation of gold nanoparticles(GNPs).Many reactions were conducted to prepare stable gold nanoparticles by usingchemical reducing agents such as (sodium tri-citrate, sodium borohydride),The reactions to prepare GNPs using these reducing agents were done at temperature of 60 – 80 °C.The resulted GNPs were characterized by UV- Vis spectra, zeta potential, atomic force microscope(AFM), scanning electron microscope(SEM), and transmission electron microscope(TEM).The absorption spectrum of the red GNPs solution appeared at the range of 520-540 nm. The gold nanoparticles which formed from various reactions have different shapes but the most prominent form is the spherical, and the sizes have also been different and appeared at the range of 14.5- 44 nm, which are consistent with published researches.
