The aim: The purpose of this study is to find out the association between procalcitonin and hepcidin in patients with COVID-19, in addition to their role as diagnostic markers. Materials and methods: A total of 75 patients infected with coronavirus were included in the current study, their age is ranging between 20 to 78 years. Those patients was hospitalized in Al-Sadr Teaching Hospital in Najaf, in Iraq. This study also included 50 healthy subjects which are volunteers and considered as a (control group). Biomarker (procalcitonin and hepcidin) measurements were achieved by electrochemiluminescent immunoassay (ECLIA) in the Elecsys immunoassay system. Results: The present study showed a significant increase the serum cencentration of hepcidin and procalcitonin in patients with COVID-19 as compared tohealthy subjects. There was a highly significant increasing(p < 0.01) in hepcidin and PCT level in patients with severe infection comparing to other catgaries.The current study also revealed that the sensitivity values of the markers were: 0.88%, 0.85 for procalcitonin and hepcidin respectively, which indicate high diagnostic power. Conclusions: Serum levels of hepcidin and procalcitonin are increased as inflammatory markers in COVID-19 patients with relatively high sensitivity. It seems that these imflammatory markers obviously elevate in the severe cases COVID-19dusease.

It was clinically and surgically proven that sixty-four patients were infected with a hydatid cyst. Follow up was done in Al-Sadder Medical City, Najaf/Iraq during the period between January and December 2018. The incidence of the prevalence of hydatidosis female was higher than that of males. The youngest patients infected was five years, and oldest was over than 70 years old. The age group 21-30 years old had the highest percentage of hydatidosis infections. The rate of infection in females 64 (61%) more than males 25 (39%). Compared to males, there was a substantial rise (P < 0.05) in females. The percentage of liver hydatidosis relative to other organs was higher (67.18%). There were many patients with big cyst size (>5cm) than those with small cyst sizes (<5cm).

Drinking water is one of the necessary and continuous human needs that cannot be dispensed for any reason and must meet the water quality standards in terms of taste and color in addition to the physical, chemical and biological specifications, and this study came to know some characteristics of the quality of public drinking water as well as drinking drinking water RO in some areas In the city of Karbala, physical and chemical quality assessment and comparison of results with Iraqi and international standards. Where some factors were measured, such as pH, turbidity, total soluble solids, hardness, calcium, magnesium, sulfate, and nitrates, and it was observed that all traits conform to Iraqi and international standards. The results also showed that all results of public drinking water were higher than the results of drinking RO water and most of the readings with regard to RO drinking water were much less than the limits permitted internationally and Iraq.
