Leprosy is one of the oldest diseases of the country and may have been brought over to this country from Egypt in ancient times. Leprosy is mose frequent in the province of Tehran, East Azarbaijan, Guilan and Mazandaran (43 per Km2) than other part of the country (13-18 per km2).The incidence of leprosy is recorded at 7.7 per thousand and 35.2 per thousand in the Southern and Northern part of the country respectively. The problem of Leprosy in Iran is not the number but rather the high incidence of Lepromatous type (57.6 %) as opposed to tuberculoid (25.4%) abases. This requires efforts for hygienic care since this variety is contagious. For this very reason the Leprosy Assistance Association has come to existence in Iran for making effort to eradicate this disease. Her Majesty the Queen, by accepting the patron ship of this organization, has brought this project to the national level. Presently, the efforts are focused on the management, treatment, prevention and rehabilitation of the Lepra patients with the sanguine hope that the disease will be controlled and eradicated from the community.

This is clinical and epidemiological study of 101 cases of diphtheria patients. 44 of these patients were male and 57 female. The majority of patients were 6 to 10 years old. Winter with 45% of all the cases had the highest seasonal incidence. The common symptoms were sore throat and false membrane in either one or both side of the throat. 50% of the patients had complication and '24% died because of the disease. Palatal paralysis was seen in 35% of the cases and was fully recovered. The worst complication was myocarditis, which was seen in 25% of the cases, and accounted for 50 % of the deaths. Altogether 24 patients died of disease 11 male and 3 female. 62.5% of the deaths occurred in the first ten days of the disease. We can say that the first ten days are the most critical ones. In only 17% of the patients could a previous contact with a diphtheria case be determined. Previous immunization reduces the complications and death of diphtheria and of the 5 immunized cases only one developed palatal paralysis with early recovery. Finally most of the patients were from lower class families and were living in crowded parts of the city.

Polarographic method is considered as an alternative laboratory technique for analytical method in determination of dissolved Oxygen and N-N03. Analytical method is a time consuming technique and is subject to several interferences due to some of constituents in sewage. In this laboratory research, the polar graphic technique with, mercury drop electrodes and titrometric method were applied in determination of dissolved Oxygen and N.N93 of several samples. Statistical analysis of the results indicates that coefficient of correlation of the results of the titrometric method to the standard in 0.9992822 while in the case of polarographic method is 0.9994417. Therefore, polarographic determination of dissolved Oxygen and N.N03 can be considered as an accurate and dependable technique. The works on 22 samples of domestic sewage in this research revealed that polarographic technique can be used just as well for determination of biochemical Oxygen demand.

A total of 153 samples of milk were collected from one to none months lactating mothers age 17 to 44 years. The protein, total nitrogen, fat, lactose and calcium content 0f these milks were determined. Marked individual variation existed in the protein lactose and fat content of the milks, which was in agreement with finding of other investigators. A gradual decrease was noticed in the protein and fat content of the milk with the increase of the age, higher in the first two months than in later months.

This study is a survey type of work on the plant tumors and their characteristics in genera1; special attention is given to those tumors which are caused by grobacterium tumefactions and also by plant hormones. The type of work and the methods are very much similar to the work of other investigators, but attempt was made to compare the results which are obtained upon the local varieties of a large group of plant species grown in Iran with those which were obtained in other parts of the world, The results obtained clearly demonstrates that the tumorogenic effect of Agrobacterium Mefaciences is not universal among all plant species, as there are some plants which are quite resistant and will not produce any tumor upon the inocu1ation of the acteria. For example tradescantia spp. did not produce any tumors neither they showed any sign of infection. On the other hand the degree of the responses toward the umorogenic effects of the bacteria was shown to be quite different among the plants which were susceptible. Sunflower (H elianthues annus) tomato (Lycopersicum esculantum) and Tobacco (Nicotiana tubacum) were most sensitive toward the bacteria and produced the largest size of the tumors, whereas plants such as the common peas (pisum sativrum) and the common beans (phasealus vulgaris) the tumors produced were very small and did not have much inhibitory effect on the growth of the infected plants as compared with, the controls. Unsuccessful attempt was made to induce tumors upon the leaf of different plants, this observation infect contradicts the results obtained by other workers and the viability of the bacteria in the tumors was also being investigated. Some results with the Hormones and also discussed in this paper, and finally histological, studies on the tumors tissue are also reported here.
