In recent years considerable interest has been focused on the plasma amino acid patterns as a possible index of protein malnutrition, in children. Thus a change in the ratio of non-essential to essential amino acids is considered to be significant in the development of protein malnutrition. The present paper reports a simplified and rapid chromatographic procedure for the determination of this ratio. Plasma is mixed with ethyl alcohol and then centrifuge. The clear supernatant is applied directly to the paper. By the present technique the working time required for the chromatography reduced.

A wide variety of helminth parasite, which is quite prevalent in Iran, can infect man by the oral route. The main sources of infections are meat, vegetables and water. Some of these parasites, e.g. Cysticercus bovis, C. cellulose, Trichinella spairalis and Anisakis larvae, are present in the tissue of food animal. Human infection establish by consuming raw or inadequately cooked pork, beef or fish. The infective stages of some helminths, e.g. Trichostrongylus spp., Ascaris lumbricoides, Trichuris trichura, Fasciola spp. Dicrocelium dendriticum and Dracuncwlus medinensis may infect man through vegetable and drinking water. Using human and animal manure as fertilizer of the soil, facilitate the transmission of these parasites to man. Contaminated food materials can pay also a role in, human hydatidosis. Hygiene is a key factor in the control of all conditions and both medical and veterinary professions have an important function in this field.

The incidence of T-strain mycoplasma was studied in 36 men with gonococal urethritis (GU), 56 men with non-GU, 59 normal, symptom-free men with no leucocytes in their urethral smears and 37 symptom-free men showing leucocytes in their urethral smears. There was no significant difference in the rate of isolation of T-strain mycoplasma in our different groups. The isolation rate for M. hominis was significantly higher in symptom-free men than in men with GU or NGU. We could not detect serological evidence of recent infection with M. hominis or T -strain mycoplatsmas in any of our 92 patients studied.
