The physiological effects of a diet free of meat and eggs were studied. Fifteen adult lacto-vegetarians were matched with non-vegetarian individuals by age, sex, body weight and height. A two-week dietary record was secured from each individual. The food consumed over a 48-hour period was measured. Venous blood samples were taken from each individual for determination of serum total protein, urea, serum creatinine, hematocrit, hemoglobin and serum cholesterol. In the vegetarians, hemoglobin, hematocrit and serum protein levels were normal; e.g. same as the nonvegetarian controls, but their blood urea level was lower for the same protein intake and their serum cholesterol, was also lower.

In this survey Aflatoxin contamination of fifty two samples of raw milk and nine samples of commercial milk were determined by T.L.C. Method. The results showed that 92.31% of the samples of raw milk and all the samples of commercial milk were contaminated by Aflatoxin M1 and M2. None of the samples contained Alatoxin B1, B2, G1 and G2. The maximum amounts of 23/. g/lit and 20.1 g/lit were found in raw and commercial milk respectively. Recommendation to prevent Aflatoxin contamination in raw milk and necessity for preparation the standards for milk, milk products and foods were suggested in this paper.

In order to prevent water losses through disposing hydrous sludge during treatment of water, also recovery and reuse of chemicals; treatment by magnesium carbonate as a coagulant was examined in batch and continuous systems. 600 mg/1 MgCO3 as optimum dosage reduced 80% turbidity of a highly turbid water containing 200 NTU. Sulfates decreased, but hardness and alkalinity showed some increases. Recarbonation by CO2 resulted in recovery of 45% of magnesium carbonate which was used again as part of coagulants in continuous system. A mixture of magnesium carbonate and calcium oxide (lime) was examined. 600 mg/1 MgCO3+250 mg/1 CaO as optimum dosage showed 90% reduction in turbidity, 10% reduction in both hardness and alkalinity and almost 60% reduction in sulfates. Recarbonation of sludge resulted in 73.5% recovery for magnesium carbonate and 40% for the lime, which were used again in a continuous system. Six hours operation of a continuous system with a detention time of 1 hour confirmed results obtained from batch analysis. A third trial was experienced with a mixture of magnesium carbonate+sodium carbonate. Although the total hardness showed more decreases, but the turbidity reduction was not satisfactory. As the conclusion, treatment of water by a mixture of MgCO3+ CaO is our choice. There will be no water losses in this method, resulting additional incomes by selling the 15-20% saved water and savings in expenditure and cost of coagulants. Cost of new constructions and CO2 production seems insignificant, comparing to savings and new income.

Dicrocoelium dendriticum is 10 by 2 mm. trematodes which live in the liver of the cattle, goats and sheep but it occasionally infects the human being. During the study of intestinal infections in the Caspian Sea region 2 cases of Dicrocoeliasis were found. The method for diagnosis was Formol-Ether concentration technique for stool examination. These two patients had eosinophilia and vague abdominal pains and digestive disorders. The following points are worthwhile to remind for the patients in the Caspian Sea region. 1. The Formol-Ether technique of stool examination is the best method for diagnosis of trematodes ova. 2. Those patients who come from the Caspian Sea region and have vague abdominal pain and esosinophilia should have a stool examination by the Formol-Ether technique. 3. In the differential diagnosis of ictrus and liver diseases one should remember the distomatosis.
