Sexuality in an aged sample: cognitive determinants of masturbation.

The examination of sexual activity in old age has typically meant a consideration of sexual intercourse. Masturbation has not received a rigorous investigation with respect to the elderly, despite benefits that may be associated with this form of sexual expression. The present study reports on the relationship of masturbation with locus of control, sexual status, and sexual knowledge as part of a more general but intensive study of an elderly sample. Results indicated that the best predictor of frequency of masturbation was locus of control, while sexual status and sexual knowledge contributed somewhat less to the variance explained in frequency of masturbation. Specifically, the data support the conclusion that internals masturbate more than externals, particularly internals with high sexual knowledge and persons without sexual partners may have a slight tendency to masturbate more often than those with partners.

Psychoeducational intervention for sexuality with the aged, family members of the aged, and people who work with the aged.

Sexual attitudes, knowledge, and behavior have been shown to be a life-long pattern of evolving behavior without a clear beginning and ending. Older persons were educated and socialized in an environment that viewed sexuality as a procreative activity appropriate only for married persons in the child bearing years, thus neglecting the interpersonal and individual aspects of sexuality. A sexual psychoeducational intervention was conducted and evaluated with older persons, adult family members of older persons, and staff members of nursing homes. Results indicated significant changes in attitudes toward and knowledge about sexuality and aging and sexual behavior.

Beta-adrenoceptors in the human dorsal hand vein, and the effects of propranolol and practolol on venous sensitivity to noradrenaline.

1 Infusion of isoprenaline into dorsal hand veins preconstricted with noradrenaline produced vasodilatation in four subjects out of five which was reversed by addition of propranolol. It is confirmed that beta-adrenoceptors are present in the hand veins of most subjects. 2 Addition of either propranolol or practolol to infusions of vasoconstrictor doses of noradrenaline potentiated the vasoconstriction in the hand vein. 3 After systemic administration of propranolol (0.3 mg/kg) or of practolol (1.0 mg/kg) intravenously, the sensitivity of the hand vein to the vasoconstrictor activity of noradrenaline was increased by 7.5 times and 2.9 times respectively. Significant reductions in hand skin temperature and resting pulse rate occurred after propranolol only. 4 It is suggested that this may be a useful method for the quantitative estimation of peripheral vascular beta-adrenoceptor blocking activity in man. At the doses used, significant beta-adrenoceptor blockade appears to occur at this site with practolol as well as propranolol.

Methylpendolmycin, an indolactam from a Nocardiopsis sp.

Methylpendolmycin, a new indole alkaloid with an N-methylisoleucine moiety incorporated in the nine-membered indolactam ring, has been isolated from an actinomycete culture of Nocardiopsis. Methylpendolmycin exhibited inhibition of phorbol ester binding to protein kinase C. Its structure was assigned on the basis of spectroscopic data.

Rapid latex agglutination compared with the throat culture for the detection of group A streptococcal infection.

The Culturette Brand rapid latex agglutination test was compared with the throat culture for accuracy in detecting Group A beta-hemolytic streptococci (GABHS) on paired throat swabs from 1047 children with suspected streptococcal pharyngitis. In this comparison the rapid latex agglutination test had a sensitivity of 78%, a specificity of 88%, a positive predictive value of 52% and a negative predictive value of 96%. In 45 study patients from whom it was possible to obtain paired acute and convalescent sera, the latex agglutination test and the throat culture were compared against each other for detection of infection due to GABHS as evidenced by a 4-fold or greater titer rise of serum antistreptococcal antibodies. The latex agglutination test detected and failed to detect the same number of infections as the throat culture. Thus although a significant number of false positive latex agglutination tests occurred when compared to the throat culture, there is limited evidence in this study that the latex agglutination test is equal to the throat culture in detecting patients who have serologically confirmed infection due to GABHS.
