Study on 48 people, of whom 16 are male and 32 are female, from 23 to 44 years old. They were long exposed with poly-chemicals, such as organic and iso-organic acids: benzene, toluene and their coequals. The parameters have been used: phagocyte capablity and phagocyte index of neutrophils; E, rossett formed T cells. The results showed that: Phagocyte capability and phagocyte index of neutrophils decreased significantly comparing with control group (p<0.001)

The fluid extract of MC (1 ml contains 1 gram fruit of MC) was used to evaluate its influence in immune index on immuno suppressive mice by CY. The fluid extract of MC in dose of 6 gram/kg body weight per oral route daily in 5 day consecutive course has increased relative weight of spleen and thymus, total leucocytes count, number of lymphocyte, natural killer and monocyte, rate of immune B rosette forming cells, plaque forming cells, the dermoreaction with OA antigen compare group that has been only injected CY without using any drug

Bilharziasis is a tropical parasitic disease caused by different species of the genus Schistosoma. One species, S. haematobium, is widely spread in Sudan. There is a scarcity of information about S. haematobium infection among the fishermen in the country. Therefore, this study was designed to determine the prevalence of S. haematobium infection among fishermen, and the immune status among non-infected fishermen in two villages, El Hadib and Hawer-Ajowel at the White Nile state in Sudan. A cross-sectional survey was conducted among 119 fishermen in addition to 20 samples from non-endemic area which were included as a control group. Urine samples were examined by sedimentation method and faecal samples were examined by the Kato Katz method and formalin-ether concentration technique. Blood samples were examined for enumeration of IgE antibody and cytokines, interferon Gamma (IFN-γ), Tumor Necrosis Factor (TNF) and Interleukin10 (IL–10) levels using ELISA. The result of the study indicated that the overall prevalence of S. haematobium among the fishermen was 35 (29.41 %). Of the 35 positive participants, 23 (65.71 %) were infected for the first time, and 12 (34.29 %) for the second time (re-infection). Twenty-four candidates of the non-infected fishermen were included in the immunological study. The total IgE mean titer was 282.90 ±70.93 iu/ml, IFN-γ mean level was 9.62±4.60 pg/ml. TNF, 114.64±46.63 pg/ml and the IL–10 was 1.51±0.58 pg/ml. High prevalence of S. haematobium exists among fishermen and the non-infected fishermen from the endemic area showed high immune response similar to those exposed to the infection.

The study was performed to measure and compare the peripheral blood T cell and T subsets in normal controls and psoriatic patients. Thirty-two normal controls and fift:en psoriatic patients were subjected to the study and the percentages and the rati vs of peripheral blood T cell and T subsets were measured. The results were as follows: 1. Mean percentages of peripheral blood lymphocytes reactive with OKT3 monoclonal antibody in psoriatic patients were 72. 8+-8. 2%, They decreased significantl) as compared with these in control group(76, 6- i-4. 7%). Mc an percentages of peripheral blood lymphocytes reactive with OKT4 monoclonal antibody in psoriatic patients were 47. 3+6, 7p;. They increased as compared with these in control group(46. 5+-3. 9p;), but the increase was insignificant. 3. Mean percentages of peripheral blood lymphocytes reactive with OKT8 monoclonal antibody in psoriatic patients were 27. 2+5. 5g, They decreased significantly as compared with these in control group(30, 6- l-4. 3%) 4. Mean ratios of lymphocytes reactive with OKT4 monoclonal antibody to these reactive with OKT8 monoclonal antibody in psoriatic patients were 1.8+- 0. 48 They increased significantly as compared with these in control group(1. 6+ 0.34).
