Tests on disposable and re-usable needles part I - disposable needles

The Drug and Therapeutics Bulletin carried out a series of tests on all brands of disposable needles available in October, 1963 (see Table I). Our tests were intended to assess and compare the different brands for sharpness, strength, non-leaking mount, and protective packaging, which are the most important requirements. In our next issue we shall report the results of similar tests on re-usable needles and shall compare the two types. Most tests were based on the British Standards (BS) 3522:1962 ‘Specification for Hypodermic Mounted Needles (Luer Fitting)’1. We tested at least 125 samples of each brand, which we bought anonymously. We tested Size No. 12 if we could get it, and, if not, the nearest size we could - No. 2 or No. 15.

Preparations from Cannabis sativa, the hemp plant, were omitted from the B.P. in 1932, and from the B.P.C. in 1949. Today, they are scarcely used in medical practice, though manufacture of a tincture of cannabis is still licenced (and one or two practitioners are known to prescribe it from time to time for psychiatric or psychosomatic disorders1). Cannabis and preparations derived from it are controlled by the Dangerous Drugs Act, yet they are more widely and increasingly used in this country and in America than any other illicit drug. But this is not the only reason for discussing their effects in the Drug and Therapeutics Bulletin: the future use of some synthetic analogues and derivatives seems probable as analgesics, antidepressants and antihypertensives.2

We are pleased to be able to announce a new service for our subscribers. With this issue, and every two months in future, they will receive the Adverse Drug Reaction Bulletin without extra charge. The ADRB has been published by the Newcastle Regional Hospital Board since 1966, but its circulation has until now been largely confined to the Newcastle Region. We believe that it deserves to be read much more widely and will be of particular value to readers of the Drug and Therapeutics Bulletin, to which it is complementary. The ADRB will retain its editorial independence, but we have arranged to print it and to distribute it for its publishers outside their region.

Most of the shipped products are sensitive against shock and vibration events during the distribution. Various cushioning materials are usually used to prevent the product damages. During the design process the protective packaging system is developed by the engineers based on the cushion and vibration transmissibility features (ie. cushion curve) of the material used. However, after the assembly of the packaged-product, these are stored for various long periods in warehouse. During this time the products pre-load the cushioning material and its parameters can be changed. The main goal of this study is to evaluate the vibration transmissibility of PE and XPE cushioning material at varied storage (pre-loaded) time and static load conditions. Four different kinds of duration (1 hour, 10 hours, 100 hours and 1000 hours) were used for the pre-loading period at three different static loads (3.488 kPa, 4.651 kPa, and 6.976 kPa), and then at 0.5 oct/min sine sweep vibration the peak frequencies of response and vibration transmissibility, and damping ratio were determined. The results show that the effect of pre-loading is minimal by PE material, but can influence the resonance frequencies by XPE cushioning material. The findings of this study help the packaging engineers to understand better the mechanism of these cushioning materials and to design suitable protective packaging systems.

Several articles in the first two volumes of the Drug and Therapeutics Bulletin have been about drugs promoted for use in anxiety, depression and other illnesses of neurotic origin. There are no signs of any impending ‘breakthrough’ in the treatment of mental illness with drugs, nor is there any lessening of the tide of drugs promoted by manufacturers for this purpose: so the time seems opportune to comment on some principles of drug therapy in this field.
