Malaria has always been regarded as one of the most important health problems with which Iran is faced. Most parts of the country, especially densely populated areas, were known as malarious areas. Records of 1947 show that 25% of cases referred to health centers and dispensaries of the Ministry of Health were due to malaria in Khuzestan and Caspian Sea areas. The mortality rate of malaria in the Khuzestan and Caspian littoral areas and Khuzestan province was reported to be about Caspian littoral areas and Khuzestan province was reported to about 30-40% of total deaths. It has been estimated that each year the number of malaria cases was between 4-5 millions. At present 2/3 of the country with a population of 23 millions is under consolidation phase and the number of positive cases in this area was 4312 in 1976. In the Southern part of Iran, which has a tropical climate with the average temperature ranging between 12-50 and the average relative humidity between 40- 50%, the malaria campaign has not been as successful as in the Northern parts. In this part of the country our malaria eradication program is faced with technical problems such as malaria eradication program is faced with technical problems such as resistance of A. stephensi to organochlrine insecticides. The development of DDT and dieldrise the resistance by A. stephensi in 1957 and 1959 practically stopped the eradication of malaria in subsequent years in this part of the country. In October 1967, the Southern part of the country with a population of about 4 millions was sprayed with malathion 2-3 times per year. This spraying was supported by monthly positive case detection, treatment of positive cases, introduction of Gambusia fish in active and potential breeding places and mass – drug administration. In the first 4 years of this campaign the annual parasite incidence came down from 8.41 per thousand to 2.1 per thousand.

Rove beetle dermatitis produced by the family Staphylinidae genus Paederus has world- wide distribution some one hundred species of Paederus have been found, but it is believed that only 30 of these produce dermatitis. Up to 1976 three species of paederus have been found in Iran as: P. fusciped Curtis; P. pietschmanni Bershaner , and P. spectabilis Kraatz . Observations on the biology of Paederus SPP have shown that the greatest activity coincides with a high degree of humidity during the hot season. Some species seem to be attracted to artificial light. The most common pathological feature caused by rose beetles is a viscular dermatitis Eye lesions may occur, but they are the result of spread of the irritant with the fingers, after the insect was crushed on the skin, therefore secondary infection. Experiments have shown that dermatitis only develops when a rove beetle is crushed on the haemolymph. The vesicant substance is pederin which is distinct from cantharidin in terns of its biological, physical, and chemical propertics.

The mean noise levels were measured in the different sections of six representative mills in the Isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. The mean noise levels were on average 95 dBA in the weaving sections and 88 d BA in the spinning sections. The audiometric findings showed a significant loss of gearing in the textile workers as compared to controls who were employed in a quiet environment. The study indicated that noisiness depended; on the whole, on the age and number of machines deployed per unit area of shop-floor. On the basis of this study certain recommendations were made to improve the working conditions.

The present study examines the hypothesis that the attitudes and behaviors of people toward dental health practice varies with such factors as locality (urban- rural) age and levels of education. For this study 1085 urban and 871 rural heads of households have been interviewed. The results indicated that locality and age influences the behaviors of the respondents but the general attitude leads no relationship to the locality.
