Abstract
The present study were made for analysis of major chemical and biochemical components of twenty hydatid cysts fluids include two group (10 fertile cysts and 10 sterile cysts) obtained from the lung and liver of 29 infected patients admitted to medicine city hospital for operation during a period of 6 month these components were measured by colorimetric assay kits (Biolabo®, Human). Results revealed marked (P<0.05).differences in the mean values, particularly among enzymes (Glutanicoxaloacetic transaminase, Glutanic pyruvic transaminase and Alkaline phosphatase), between fertile and sterile fluids while Lactate dehydrogenase level was exhibited high activities in fertile and sterile isolates, these values was less than normal values in serum . The mean values of Iron, Zinc Sodium Phosphorus and potassium, were found higher in fertile isolates, while marked decrease in sterile isolates. Furthermore, the Copper revealed quantitative differences (P<0.05) between the two isolates. Manganese and chloride constituted the major volume in the fluid anions, in fertile and reach maximum in sterile fluid. Differences were detected in the levels of glucose of fertile which increased significantly (P<0.05). The data detected no significant difference (P>0.05) in total protein which exhibit high in fertile and sterile fluid. Also Calcium and Magnesium mean values revealed same in both isolates. Trace elements like Urea, Uric acid, Bilirubin Creatinine and Lipid increase in liver diseases such as (Cholesterol, and Triglycerides) level was found higher in fertile and sterile isolates. In compare with previous studies the present investigations reflected quantitative difference in mean values of biochemical parameters of fertile and sterile of hydatid cyst fluids contributed to fertility of cyst and viability of protoscoles. Fertile cyst which contain broad capsule and protoscoles which responsible of high concentration in these elements than sterile fluid which lack the broad capsule and protoscoles , which may pointed some variable in parasite metabolism endurance, growth rate, intermediate host specificity location of cyst among lungs or livers or even strain variation.

The non-organic substances detected in hydatid fluid are potassium, magnesium, calcium concentrated in protoscolices as compared to cyst fluid
The stored fluids were transferred in cold container to Monthar lab in Al Saadon area in Baghdad for chemical and biochemical components analysis, using colorimetric assay kits (Biolabo®, Human) and (Biolabo®) company France, and according to the manufacturer’s instructions the components were measured including magnesium, copper, potassium, Sodium chloride, Zinc and Calcium
Summary
Introduction functional antigensHydatid fluid is richCystic echinococcosis (CE) is a disease caused by the metacestode hydatid cyst of the adults tapeworm Echinococcus granulosus. The disease caused economic loss include decreased in fecundity, meat and milk production, reduced hide and fleece value due to condemnation of edible organs. While [4] demonstrated that hydatid cyst fluid antigens Ag) are variable in their antigenicity according to the host, localization of cyst and fertility or development stage of the cyst. The metabolic products of the protoscolices which accumlate in the fluid are responsible for the potential antigenicity, this explains the poor antigenicity of cysts lacking protoscolices. Sheep and human HF are considered to be highly antigenic among other intermediate species. Liver HCF antigens considered to be better than lung HCF antigens due to the high concentration of protein content. The aim of this study was to investigate variation in the chemical and biochemical components in fertile and sterile hydatid fluid of human
