HIV/AIDS--an issue in nurse education.

The White Paper, The Health of the Nation (Department of Health 1991), identifies education in HIV/AIDS as an area of priority concern. Statistics have shown that education aimed specifically at gay men has been reduced and that, at the same time, the incidence of infection within this group has risen. There would appear to be a relationship between education targeted at a group and the behaviour of that group. For nurses there are similar implications. A study published in 1992 found that there was widespread ignorance among nurses and that education and training targeted at the specific needs of nurses was the answer. There have been a number of other research studies which have focused on other aspects of HIV/AIDS education. The issues involved include: highlighting infection control, the education of Health Care Assistants, prejudice and attitude, the credibility of teachers. This study shows how a course on HIV/AIDS can be tailored to meet the identifiable learning needs of nurses as an ongoing process of monitoring and evaluation. The process endeavours to address the issues in a way that has maximum effect on the learning process and takes account of a range of studies in order to meet the requirements of the Health of the Nation White Paper.

Validation of self-reported cannabis use by urine analysis.

A study of 113 young multiple drug users, interviewed at one year follow-up, was designed to assess the validity of self-reported cannabis use. Subjects provided information about the recency, frequency and typical dose of their use of cannabis in the preceding 30 days. Urine samples were collected and analyzed for delta 9 THC metabolites. Recency of use was the best predictor of urine test result, but a measure of frequency of use significantly increased the proportion of variance accounted for. The results strongly supported the validity of self-reported cannabis use and indicate that valid self-reports of drug consumption can be obtained from multiple drug users in treatment.

Coelomic fluid and blood serum proteins of the metamorphosing bullfrog tadpole.

Bullfrog (Rana catesbeiana) tadpoles were divided into four groups containing Gosner ('60) stages as follows: I, 27-31; II, 32-36; III, 37-41; IV, 42-46. Extractable coelomic fluid volume from late metamorphic tadpoles (Group IV) was found to have a highly significant (p less than 0.001) negative correlation with stage; tadpole weight also had a negative correlation with stage (p less than 0.025). No significant correlation was found between coelomic fluid volume and tadpole weight. Group IV blood serum protein levels (x = 1.30 +/- SEM 0.10 G/100 ml serum) were shown to be significantly higher than corresponding coelomic fluid serum protein levels (x = 0.80 +/- 0.06 G/100 ml). Electrophoresis data demonstrated an increase in the albumin fraction of both blood serum and coelomic fluid during metamorphosis. I-125 labeled human serum albumin equilibrated with the blood serum at equal concentrations about ten hours after an intracoelomic injection. A coelomic fluid turnover time fo 26% per hour was calculated from the tracer data. We hypothesize that a slight sieving occurs at the coelomic fluid inflow site with none at the outflow site.
