ABSTRACT
This work comprised 18 patients with variable degrees of bilharzial corpulmonale and 18 control subjects of different age and sex. They were subjected to thorough clinical examination and different laboratory, radiological, electro-cardiographic and pulmonary function investigations. It was found that, respiratory functions was impaired in patients with bilharzial corpulmonale, both restrictive and obstructive ventilatory dysfunctions. The clinical grading gives an diea about the obstructive dysfunction while radiological grading given an idea about the restrictive ones. On the other hand the clinical grading more or less equal to the radiological grading, So, the clinical examination can tell us abuot the expected radiological findings in those patients
