Bilharzial bladder tumour of 28 patients staged pre-operatively by transurethral ultrasound and computerized tomography (CT). The accuracy varied from 66.6% to 77.7% in different stages as compared with pathological stage. The bilharzial reaction could be play a role in this accuracy and the histopathological study is the accurate way to express the depth of infiltration of the tumour in the bladder wall as well as the depth of vascular invasion which may be greater than the primary tumour itself.

Delta hepatitis is a relatively common in Egypt especially in patients with chronic liver disease. Delta virus infection is associated with a high frequency of hepatic decompensation and it seems to impose additional burden on liver function. It does not seem to be more prevalent in particular type of cirrhosis but the CAH pathology was found to be mostly associated with virus infection. HBV replication seems to be inhibited by the presence of delta virus as evidenced by the low frequency of HBe Ag in serum and HBs Ag in liver among patients with HDV infection.

The Counter current immunoelectrophoresis (CEP), the Enzyme linked immunosorbent assay (ELISA) and the Indirect immunofluorescent (IF) were evaluated in detection of antibodies in naturally infected rats. The test subjects included ten infected rats as indicated by digestion method of muscle biopsy and 13 rats free from trichinosis. Of the immunodiagnostic tests evaluated, the CEP gave the highest diagnostic accuracy. The ELISA was the least accurate. The high sensitivity and specificity of the CEP for detection of anti-trichinellal antibodies suggest that it could be developed as a serodiagnostic test for trichinosis.

The HLA-DR antigen type was studied in fifty-four patients with bilharzial bladder carcinoma and in ten patients but with non malignant bilharzial bladder lesions as controls. The monoclonal antibodies were used to identify the pattern of the distribution of lymphocytes subset and the natural killer cells. These immunohistochemical studies through some light on the relation between the different immunocompetent cells in the bladder tissue and suggested their functional role particularly in bilharziasis and in the tumour surveillance.

Human sera (330 from patients with manifestations suggestive trichinosis) were examined for antibodies. The immunologic tests used were counter current immunoelectrophoresis (CEP), enzyme linked immunosorbent assay (ELISA) and immunoflourescence (IF). Seropositive reactions were demonstrated in 2.7%, 5.4% and 2.4% of the sera by the 3 tests respectively. However, 2.4% of the sera were seropositive by the three tests. It seems that the use of two of these tests is valuable in diagnosis when muscle biopsy is unproductive.
