Interaction between soluble immune complexes and glass-fiber filters.

The two components of soluble antigen--antibody complexes, at the antigen excess, exhibit an increase in their binding ability to glass-fiber filters. This is demonstrated in two systems. In the 125I-BSA--anti-BSA system the proportion of 125I-BSA bound to the filter is markedly increased in the presence of anti-BSA antibodies. More than 80% of the antibody bound BSA can be removed by passage through the filter. In the other system, mouse gamma globulin (MGG)--125I-anti-MGG, the proportion of antibody bound to the filter increases with the increase in antigen concentration, whilst the presence of another, non-related, gamma globulin has little effect on the binding. The possible mechanisms for the binding of soluble complexes to the glass fibers are suggested and discussed.

The effects of erythrocyte-absorbed H-2 alloantisera on mixed lymphocyte culture reactions.

One-way mixed lymphocyte culture reactions were inhibited by the addition of H-2 alloantisera directed against the stimulator cell type. The sera retained their original inhibitory activity after the removal from them of conventional H-2K antibodies by exhaustive absorption with erythrocytes. The absorbed antisera had specificity for Ia but not H-2 antigens thereby indicating that the inhibitory activity of the sera is a function of antibodies against I region products. H-2 and Ia alloantisera directed against the responder cell type did not specifically inhibit culture reactions: they either had no effect or they apparently increased stimulation. This increase appeared to be immunologically specific, at least in part, and to require some heat-labile normal serum component for its elicitation. It is concluded that treatment of responder cells inactivates or destroys some normally inactive or inhibitory subpopulation such that the remaining cells respond better to allogeneic stimulation. Both the anti-stimulator and the anti-responder effects were seen with either whole serum or crude immunoglobulin preparations when one of these was added to the culture or used for pretreating cells before establishing the culture.

Drug misuse in a special clinic patient population in Glasgow.

During the period October, 1970, to October, 1972, a sample of 295 patients attending Special Clinics in the City of Glasgow participated in an investigation into drug misuse. Results show that, of the 136 males and 159 females who took part--all within an age range of 16 to 24 years, 43 per cent. of the males and 36 per cent. of the females admitted to having experimented with drugs. These percentage figures on the prevalence of drug misuse compare with 36 per cent. of males and 24 per cent. of females obtained from other Glasgow-domiciled target groups, comprising a sample of 2,514 individuals. The principal drug of misuse is shown to be cannabis, followed by LSD and sleeping pills. Data on drug availability suggest that little difficulty is experienced in obtaining drugs illicitly from a variety of sources. Comparison between drug misusers and non-misusers on domestic, educational, and social variables revealed no very distinctive patterns. Results of screening for personality characteristics, using Eysenck's Psychoticism, Extraversion and Neuroticism Inventory generally confirmed previous findings related to atypical scores on the P, E, and N parameters. Even so, results obtained by means of the PEN Inventory and IPAT Anxiety Scale revealed a pattern in which drug misuse is shown to be related to even higher scores of psychoticism, neuroticism, and anxiety. The results of the investigation are discussed with particular reference to the nature of the appeal of drugs to the sexually permissive and promiscuous.
