Small-scale trial of live-attenuated influenza vaccine (A/Hong Kong/68).

Seventy-one men who were given live-attenuated A/Hong Kong/68 (H3N2) influenza vaccine during November 1973, and 34 men given placebo were examined for changes in antibody level. Overall, 12 of the 71 men (17%) given the vaccine showed a fourfold rise in haemagglutination-inhibition (HI) antibody titre after 14 days. No such rises were seen in the 34 men given placebo. However, 10 of the men showing a fourfold rise were from 19 who had no detectable HI antibody to this virus before vaccination, representing a conversion rate of 53%. The other two had a HI titre of 1/10 before vaccination. The absence of antibody response, at 14 days, in those with an HI titre of 1/20 or greater may indicated that this represents a protective level against infection. However, the vaccine virus was probably overattenuated and may have constituted a weaker challenge than might occur with a wild strain. No influenza virus was isolated from either group in the week after vaccination and no evidence of transmission to the placebo group was seen. Mild symptoms, chills, muscle pain, and stiffness were more frequently seen in the 12 persons showing a fourfold rise in antibody than in the rest of the volunteers.

The protective effect of glucose-insulin-potassium on the response to atrial pacing.

The effects of glucose-insulin-potassium infusion (GIK) on atrial pacing-induced angina, ST depression, abnormal left ventricular end-diastolic pressure during pacing interruption (LVEDPi) and lactate metabolism (L), were studied in 18 patients: ten had angina during pacing = Ischemic group, and eight (5 normals and 3 with coronary artery disease) remained asymptomatic = Nonischemic group. The study consisted of 8-10 minute periods of control, pacing and recovery, before and after GIK. No untoward effects were observed. Comparison of the pacing responses (GIK vs pre-GIK states) showed that during GIK, angina occurred in only 4 patients, while significantly less severe changes were observed in ST depression (1.4 +/-0.5 vs 2.4 +/- 0.4 mm) and LVEDPi (16 +/- 3 vs 23 +/- 3 mm Hg). Lactate extraction was also higher (8.1 +/- 10.9 vs -5.2 +/- 11.1%), but not significantly so, although L became normal in 4 subjects and improved in another. These results indicate that GIK infusion was well tolerated and had a beneficial effect on pacing-induced myocardial ischemia.

Qualitative vocabulary test responses and age.

Vocabulary test responses, as traditionally scored were compared to these same responses when scored for finer nuances of understanding, as determined by the criterion of superior synonyms. It was hypothesized that the latter would be more related to age in a deficit pattern than the former. The results partly supported the hypothesis and partly not. In the context of the positive results, it is not clear whether the aged cannot, or simply do not, give synonym responses as readily as the young. It may be more of a cohort preference not to, rather than an age limitation of intellectual ability.
