A prospective study of the hazards of multiple use of disposable syringes and needles in intensified insulin therapy.

The aim of the present study was to evaluate the potential hazards of multiple use of disposable syringes and needles for insulin injections over a long period of time. A special syringe container (pen-case) was developed to carry the syringe with insulin. In the microbial trial 24 patients, each injecting insulin for 1 week with one disposable needle, were studied for 201 patient-weeks with 5829 injections.

Antiphlogistics in periodontology.

In 146 individuals with inflammatory periodontal disease the authors verified the therapeutical effect of Sanchelin (the mixture of sanguinarine and chelerythrine in 0.05% concentration) in gel (4% hydrogel carboxymethylcellulose) applied into pockets and in aqueous solution administered in the intrapapillar route. The effect of Sanchelin in solution was compared with the effect of 2% hydrocortison in the same way of administration.

Staphylococci outside the hospital. Staphylococcus aureus in sheep.

Biochemical properties were studied in Staph. aureus strains obtained from the anterior nares of healthy sheep and from the udders of ewes suffering from purulent mastitis. Of the total number of 84 isolated staphylococcal strains 75 (89.

A comparison of antigenic structure and phage pattern with biochemical properties of Staphylococcus aureus strains isolated from sheep.

Of 84 Staphylococcus aureus strains isolated from the anterior nares of healthy sheep and from the udders of ewes suffering from purulent mastitis the 89 per cent belonging to the C biotype contained agglutinogen h2 as well as polysaccharide Abeta. Ninety-five per cent of the C biotype strains were lysed by the bovine phage 78, the human phage set giving only weak reactions at RTD X 100. Two pigment-negative deficit variants as well as three unclassified strains gave similar results while three A biotype strains and one E biotype strain were definitely different.
