Objectives: Manufacturing and spraying workers of organophosphate pesticides (OPs) could suffer from testicular spermogenesis and steroidogesis dysfunctions particularly when their degradation is subnormal. Aim: Exploration of spermatogenic and endocrinologic testicular functions and paraoxonase/arylesterase (PON1/ARY) degrading activities of the organophosphate parathion and its oxon in their ...

Both urinary bilharziasis and urothelial neoplasia are associated with increased production of tissue carcinoembryonic antigen (CEA). Urine and serum CEA were determined in 43 patients with urinary bladder carcinoma including 22 post bilharzial and 21 non-biharzial cases, in addition to 10 normal control cases. A significant increase was detected in both urine and serum CEA levels with bladder ...

Ileal loop replacement is often the only possible treatment for extensive bilharziasis of the ureter. Experience with 5 such cases is presented and the special problems arising from the nature and extent o f the lesion are discussed. In bilateral cases, attempts should be made to preserve as much renal tissue as possible. Non-functioning kidneys in 3 cases were not removed and a degree of funct...

In this paper, the evaluation of two features in predicting the outcomes of patients with bilharziasis bladder cancer has been investigated using an RBF neural network. Prior to prediction, the feature subsets were extracted from the whole set of features for the purpose of providing a high performance of the network. Throughout the analysis of the prognostic feature combinations, two features,...

Radiological study Excluding repeat investigations, 1,525 successful intravenous pyelograms, comprising all those performed on African and Indian patients during 1964, were reviewed. In addition to noting the original radiological reports, we re-examined the radiographs for abnormalities, including evidence of possible bilharziasis. When either hydronephrosis or radiographic non-function of a k...

The organo-phosphorus compound Dipterext (trichlorphon; OO-dimethyl-2,2,2,-trichlorethyl phosphonate) has attracted considerable attention during the past few years. Besides its use as an insecticide, an attempt has been made to employ this substance for the treatment of intestinal parasites (Beheyt, Lebrun, Cerf, Dierickx, and Degroote, 1961 ; Cerf, Lebrun, and Dierickx, 1962). Schistosomiasis...
