This study aims to realization the conceivable therapeutic of melatonin effects experimental against Enterobius vermicularis in rats. Implement this experiment during the period from August 2019 to January 2020. E.vermicularis infected with male wistar rats orally with dose 15mg/kg melatonin former of body weight for 30 day showed significantly reduction in the number of eggs and worms compared with rats orally with dose 15mg/kg melatonin accompanying and untreated rats for 30 day (P < 0.05).Histologically in intestine examined show increase numbers of leucocytes produce, necrosis significant scatter and reduction this parasite of tissue in rats treated with melatonin. This results show influence of melatonin in the control on Enterobiosis and suggestion that this drug usefulness in Enterobius vermicularis infection therapy.

In order to know the efficiency of sterilization in eliminating parasites and its suitability for environment measurements, samples of the water and sediments was taken from six stations the Euphrates River. The samples were transported in clean and sterile bottles to the laboratory. A sedimentation method was used for parasites. Ten species of parasites isolated from water of the six stations while isolated seven were exists in the sediments of these stations. The water and sediments of the station first were contaminate with parasites rate 25.8% and 13.7%, the water and sediments of the second station are contaminated with parasites rate 12.8% and 20.2%, the water and sediments of the third station are contaminated with parasites rate 4.2% and 18.2%, the water and sediments of the fourth station are contaminated with parasites rate 22.8% and 18%, the water and sediments of the fifth station are contaminated with parasites rate 12.0% and 5.4% and the water and sediments of the sixth station are contaminated with parasites rate 12.9% and 1.7%. Giardia lamblia rate 25.4% it is most found in water while Trichomonas hominis rate 18.4% It is most found in sediments. A result of the study shows significant difference between of the temperature of air and water in all study stations, the air temperature ranged (40.10–15.2
C) and the water temperature between (26.3–9.4
C) while PH was (9.89–7.5), recorded electrical conductivity (5745–2515 ls/cm) and salini
