In a preliminary study carried out in a simple field laboratory in Bandar-Abbas, southern Iran, five isolates of P. falciparum collected from the patients was cultured in RPMI 1640 medium with human serum in the tightly closed screw capped vials without any devised system for adjustment of co2 and o2 mixture. The same isolates were also cultured, simultaneously, in Petri-dishes using Jensen-Trager candle, jar method. Although, the cultures could not be maintained more than 27 days, mostly due to unfavorable conditions existed in the laboratory, the longevity of parasites were more or less the same in both techniques. In this study the multiplication rates of parasites in the screw capped vials were higher than rates obtained in Petri dishes in candle jar method.

The prevalence of varicose veins was studied in 1742 male weavers in Iran by completing a specially designed questionnaire and medical examination. To show the effect of occupation on the prevalence of the disease, similar study was conducted on a group of 1661 food- processing workers. The over- all prevalence of the disease in the weavers (26.12%) was significantly higher than the similar rate (5.90%) in the other group. A direct relationship between the prevalence of the disease and age was observed in both groups; however, the increase was more significant among the weavers. A direct relationship was also seen between the length of employment and the prevalence of the disease in the weavers only. Comparison of the severity of disease in the two groups indicates that weavers not only had a higher prevalence rate, but had more severe forms too. In conclusion, it may be said that varicose veins could be a health problem in the weavers and might be substantially reduced by preventive measures.

The first records of Anopheles fluviatilis resistance to DDT was reported in 1963 from India and to dieldrin from eastern Saudi Arabia in 1959. In southern Iran, antimalaria measures began in 1950 and up to 1957 the area was under DDT residual house spraying at the rate of 2g /m2 one round/year. During 1958-59 dieldrin was used at 0.5 g/m2, 1or 2 rounds/year was applied in the lowland areas. In the highlands, where the malaria vectors are An.stephensi, An.dthali, and An.fluviatilis, remained susceptible to these insecticides.

The role of enterotoxigenic E.coli as a causative agent in diarrheal disease was studied among 100 cases of infant and children 0-2 years of age. Routine bacteriological methods were used for identification enteropathogenic E.coli, Salmonella, Shigella and Vibrio cholera. The ability of E.coli strains to produce toxin was assayed in animal models (rebbit-ileal loop and suckling mice) and in tissue-culture (Y1-adrenal cell). A total of seven enterotoxin producing strains of E.coli were isolated. Three of these strains were producing both (heat-labile-LT) and heat-stable (ST) enterotoxin). The other four strains were producing only heat- stable enterotoxin which was lost during storage. The rate of isolation for other enteropathogenic bacteria such as Salmonella, Shigella and enteropathogenic E.coli was 7%, 4% and 13% respectively. No Vibrio cholera or yersinia enterocolitica was isolated from the age group under the study.
