    The study of 10,504 cases of industrial accidents, involving 590,164 injured workers employed in different industries in Tehran industrial pole during one year shows that the over all incidence rate is 17.80 with a significant variation in regard to age and the type of industry. Furthermore, 96.58% 0t accidents have happened within the workshops. Considering the final outcome of the accidents, 0.75% of all accidents, which terminated in death, involve only male workers and 0.29% of insured workers suffer from some degree of disability.

    Due to the limitations of the “life table method” the exponential model was used to estimate the IUD termination and retention rate among 1,390 women. Since the conditional probability of IUD termination during the first month of insertion is considerably higher than the subsequent months, data relating to the first 30 days was considered separately. Furthermore a constant termination rate was assumed for the remaining period of observation. Comparison was made between the estimates obtained by our method and the results obtained from the life table method. In the majority of cases the difference between the estimates was in the third decimal figure.

    The exact cause or causes of Hodgkin's disease have not yet been determined. The etiology of the disease suggests, but has not verified, a possible immunological and/or viral relationship. The article reviews the literature on the epidemiology and etiology of Hodgkin’s disease from 1955 to the present. The author presents several clinical phenomena that are commonly associated with Hodgkin’s disease and which may be useful as diagnostic tools in cases of suspected Hodgkin's disease or with suspicious pathology. The author concludes by suggesting possible areas for future research.

    During 1979-77 a large number of Kurdish populations in northern part of Iraq temporarily immigrated to Iran and settled in Dezful area of Khuzestan province, south-west Iran. Faecal examination of 3,263 samples for intestinal metazoan parasites and 1,154 urine samples for detecting Schistosoma haematobium, infection were performed in different sex and age groups. The percentages of prevalent intestinal helminthes infection were: Ascaril11umbricoides 25%, Trichuris trichiura 16.3%, Hymenolepis nana 14%, Trichostrongylus spp. 2.5% and Hookworm 0.8%. Out of 1,154 urine samples only one infected case of S. haematobium from a 10 ears old male child were detected.

    In order to compare the enzyme-linked immunosorbent assay (ELISA) and indirect fluorescent antibody technique (IFAT) in detection of malarial antibodies, 652 sera samples collected in the Health Survey Project (1975) in a random sampling method from about 10% or residents of selected villages in Bandar Abbas and Minab areas of Southern Iran, were tested with the above two serological methods. In microscopical examination of blood films malaria parasite (P. vivax) was found in 12 cases. Malarial antibodies were detected with Aotus P. falciparum and P. vivax malaria antigens in titers ≥ 40 in 2"4.3% find 34.9% respectively. The ELISA values with Aotus, P. falcifJCIrum antigen in 15.6% were more than 0.2 In general, the IF AT showed a considerably higher positively rate than the ELISA. The result of both types of serological assay indicated a progressive incoming of positivity rate and antibody level with the age. In the present study malaria antibody was not detected by ELISA. In some P. vivax parasitologlcally proved cases; perhaps due to the using of heterologus P. falciparum antigen. The use of mixed polyvalent P. falciparum and P. fieldi malaria antigens was more efficient in detecting highest titres of malaria antiboies.
