The research was performed by isolating some species of soil- fungi from agricultural soils
handling with different pesticides and fungicides. Where the following fungi were isolated:
Aspergillus niger (The isolates A1 and A2), Fusarium oxysporum (
The isolate F),
Trichoderma harzianum (The isolate T). Also F. solani (The isolate F7) and T. viride (The
isolate T.v) were used, whereas they were taken from high studies laboratory- Science
Faculty- Tishreen University at a previous search.
The research was conducted to assay the ability of the previous fungi to degradation a
number of pesticides, the insecticide "Dolan", the insecticide "Plantocide", the nematicide
"Vydate" and the fungicide "Bayfidan", through the effect of double dose of each
pesticides in the biomass of the studied fungi on PDB medium. In addition to analysis the
results residues of pesticides using Spectrophotometer, and evaluation the pH values.
This research outlines the legal regulations for this kind of pollution
in Iraq, Egypt and Syria by defining pesticides, their source and
harmful effects on humans and the environment; and then outlining
the laws that control it in the above-menti
oned countries which put
preventive and punitive measures to protect air from pollution by
pesticides to ensure the best level of protection of public health; one
of the aims of administrative regulations for the protection of the
environment. It also presents applicable suggestions and
recommendations that help any one who aims at reaching good
management of pesticides and a clean environment.
The aim of this study is to evaluate the combination of
autologous factors, platelet rich fibrin (PRF), with bone grafts,
beta tricalcium phosphate (βTCP), In Improving the Prognosis of
Surgical Treatment of periapical lesions .
Mitochondria are the major organelles in eukaryotic cells primarily responsible for many cellular functions. Recently, a decrease or increase in mtDNA copy number has been increasingly recognized in human cancers.
