Differences in social interaction- vs. cocaine reward in mouse vs. rat

We previously developed rat experimental models based on the conditioned place preference (CPP) paradigm in which only four 15-min episodes of dyadic social interaction with a sex- and weight-matched male Sprague Dawley rat (1) reversed CPP from cocaine to social interaction despite continuing cocaine training, and (2) prevented the reacquisition/re-expression of cocaine CPP. In a concurrent conditioning schedule, pairing one compartment with social interaction and the other compartment with 15 mg/kg cocaine injections, rats spent the same amount of time in both compartments and the most rewarding sensory component of the composite stimulus social interaction was touch (taction). In the present study, we validated our experimental paradigm in C57BL/6 mice to investigate if our experimental paradigm may be useful for the considerable number of genetically modified mouse models. Only 71% of the tested mice developed place preference for social interaction, whereas 85% of the rats did. Accordingly, 29% of the mice developed conditioned place aversion to social interaction, whereas this was true for only 15% of the rats. In support of the lesser likelihood of mice to develop a preference for social interaction, the average amount of time spent in direct contact was 17% for mice vs 79% for rats. In animals that were concurrently conditioned for social interaction vs cocaine, the relative reward strength for cocaine was 300-fold higher in mice than in rats.Considering that human addicts regularly prefer drugs of abuse to drug-free social interaction, the present findings suggest that our experimental paradigm of concurrent CPP for cocaine vs social interaction is of even greater translational power if performed in C57BL/6 mice, the genetic background for most transgenic rodent models, than in rats

Antibiotics for sore throat.

BACKGROUND: Sore throat is a very common reason for people to present for medical care. Although it remits spontaneously, primary care doctors commonly prescribe antibiotics for it. OBJECTIVES: To assess the benefits of antibiotics for sore throat. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) and the Database of Abstracts of Reviews of Effects (DARE) (The Cochrane Library, Issue 1, 2006), MEDLINE (January 1966 to March 2006) and EMBASE (January 1990 to December 2005). SELECTION CRITERIA: Trials of antibiotic against control with either measures of the typical symptoms (throat soreness, headache or fever), or suppurative or non-suppurative complications of sore throat. DATA COLLECTION AND ANALYSIS: Potential studies were screened independently by two authors for inclusion, with differences in opinion resolved by discussion. Data were then independently extracted from studies selected by inclusion by two authors. Researchers from three studies were contacted for additional information. MAIN RESULTS: There were 27 studies with 2835 cases of sore throat. 1. Non-suppurative complications: There was a trend for antibiotics to protect against acute glomerulonephritis, but there were insufficient cases to be sure. Several studies found antibiotics reduced acute rheumatic fever by more than two thirds (relative risk (RR) 0.22; 95% CI 0.02 to 2.08). 2. Suppurative complications: Antibiotics reduced the incidence of acute otitis media (RR 0.30; 95% CI 0.15 to 0.58); of acute sinusitis (RR 0.48; 95% CI 0.08 to 2.76); and of quinsy (peritonsillar abscess) compared to those taking placebo (RR 0.15; 95% CI 0.05 to 0.47). 3. SYMPTOMS: Throat soreness and fever were reduced by antibiotics by about one half. The greatest difference was seen at about 3 to 4 days (when the symptoms of about 50% of untreated patients had settled). By one week about 90% of treated and untreated patients were symptom-free. The overall number need to treat to prevent one sore throat at day 3 was just under six (95% CI 4.9 to 7.0); at week 1 it was 21 (95% CI 13.2 to 47.9). 4. Subgroup analyses of symptom reduction: Analysis by: age; blind versus unblinded; or use of antipyretics, found no significant differences. Analysis of results of throat swabs showed that antibiotics were more effective against symptoms at day 3, RR 0.58 (95% CI 0.48 to 0.71) if the swabs were positive for Streptococcus, compared to RR 0.78 (95% CI 0.63 to 0.97) if negative. Similarly at week 1, RRs 0.29 (95% CI 0.12 to 0.70) for positive, and 0.73 (95% CI 0.50 to 1.07) for negative swabs. AUTHORS' CONCLUSIONS: Antibiotics confer relative benefits in the treatment of sore throat. However, the absolute benefits are modest. Protecting sore throat sufferers against suppurative and non-suppurative complications in modern Western society can only be achieved by treating many with antibiotics, most of whom will derive no benefit. In emerging economies (where rates of acute rheumatic fever are high, for example), the number needed to treat may be much lower for antibiotics to be considered effective. Antibiotics shorten the duration of symptoms by about sixteen hours overall
