Three hundred twin births from a hospital in Tehran, Iran have been analyzed for seasonal variation at birth and physical measurements. The results show that the highest twinning rates for MM (5.61), FF (7.73) and MF (5.36) were seen in April, January and September, respectively. The four physical measurements at birth showed non-significant differences among the male and female twins, but MM and M twins showed higher physical measurements compared with those of FF and F twins. Mean weight was 2441.14 (MM), 2467.29 (M), 2391.45 (FF) and 2424.38 (F) ; that of the stature was 47.40 (MM), 47.36(M), 46.78(FF) and 46.26(F); that of head circumference was 32.40 (MM), 32.30(M), 32.11(FF) and 30.64(F); and finally that of the chest girth was 29.61 (MM), 29.84(M), 29.01(FF) and 29.30(F).

In the field trials of slow-release nollusicide, copper content McCkechnie Chemical Inc. 30 cuso4 5H2o or 7.5 cupellet/sinking material 7 days release life were tested against the common aquatic snails bulinus truncatus, Physa acuta and Lymnaea gedrosiana in stagnant water bodies in Khuzestan province, south-west of Iran. Snail densities before treatment and 7 days after mollucicide application were determined by 10 deep nets per man. The results of the present trials as shown on tables 1, 2, 3 and 4 indicate that the effect of different concentration of copper based slow-relased mollnscicide (7.55 cu) is different for different species of aquatic snails. The maximum concentration to achieve 100 ppm. Mortality rate was 20 ppm for Lymnaea gedrosiana, 100ppm for physaacuta and over 120ppm for Bulinus truncatus. The high susceptibility of lymnaea snails to the chemical is very promising for the control of livestock trematodes infection in this area.

The objective of this research was to study the feasibility of a two stage continuous system employing anaerobic-aerobic microbial film for domestic wastewater treatment and the effect of iron on the behavior of sulfate reducing bacteria in anaerobic metabolism. A bench scale system with an anaerobic filter followed by aerobic fixed units used plastic media and was operated in up flow manner with hydraulic detention times of 6 hours, whereas the aerobic unit utilized diffused aeration. Raw domestic sewage was fed to the anaerobic unit, and the aerobic unit was fed with the anaerobic unit was fed with the anaerobic effluent. Although, the anaerobic filter did not show a considerable organic removal with domestic sex age it was improved when glucose was added to the influent to increase influent soluble COD. When glucose was added the anaerobic filter removed about 290 mg/1 of influent soluble COD. The aerobic unit produced an excellent effluent with COD, BOD5 and TSS concentrations of 37 mg/1, 9 mg/1 and 10 mg/l respectively. Overall, the system removed 95 percent of influent COD, 97 percent of influent BOD5 and 96 percent of influent TSS.

During 1980-82, a total number of 4143 stool samples, from 2332 males and 1811 females, referred to the Central Laboratory of the School of Public Health, were examined for intestinal parasites. All the specimens were examined for intestinal parasites. All the specimens were examined by formol-ether concentration and wet-mount (ringer solution) techniques. The main prevalent pathogenic parasites were Entamoeba histolytica (8.7%), Giardia lamblia (16.1%), and Hymenolepis nana (3.2%). The overall infection rate with protozoa, metazoan and both were 45%, 18.3% and 53.8% respectively.

A general rodent control program was carried out in Bandar Abbas in the Persian Gulf (15 Sep-22 Oct 1984). Researches on the variety of the rodents and their parasites were done and Zincphosphide and Comatetralil baits were used for in-doors and out-doors. Results obtained showed that these campaigns were successful.

From 687 patients referred to the Medical Mycology Depatment of the school of public Health, 184 cases showed Tinea capitis infection, direct microscopy and culture was positive in 86.2% and 75.29% of the cases respectively. From the positive cultures 5 different dermatophtes were identified as: Microsporum canis, Trichophyton violaceum, Trichophyton verrucosum, Trichophyton schoenleinii, Trichophyton mentagrophytes. M. canis was found to be the commonest causative organism of Tinea capitis in Tehran (53, 84%) followed by T.violaceum (22.37%), T. verrucosum (13.98%), T.shoenleinii (11.18%) and T.mentagrophytes (6.69%). Candida albicans and other candida species were also isolated from two patients.
