Use Of Hypodermic Needle Research Articles

The Practice ofInjekśanTherapy in Ayurveda

The distribution of Western pharmaceutical products in the Third World has created particular problems for traditional healers practising holistic approaches to health. This paper looks at the impact of ‘injection therapy’ on Ayurveda, the Brahmanical healing tradition of south Asia. The use of hypodermic needle and syringe is alien to Ayurveda but in the last several decades has become almost standard practice. The present study forms part of a detailed analysis of the clinical practice of one Ayurvedic healer who works on the Indo-Nepalese frontier. At his clinic penicillin is frequently administered by injection, its efficacy being interpreted holistically in terms of the equilibrium theory of illness. Although the healer recognized that penicillin recently came to south Asia from the West, nonetheless he asserted that penicillin was known to Brahmanical sages of the past. By claiming that this modern antibiotic was known to the ancients, the autonomy of Ayurveda is maintained.

A reliable method for repetitively bleeding rabbits from the central artery of the ear

A method is presented for repeatedly bleeding rabbits from the central ear artery. The use of hypodermic needle with the hub removed provides a smooth flow of blood and avoids the problem of clot formation in the hub. Blood can be obtained aseptically and free of hemolysis with little risk to the animal. Volumes of 35 ml can be obtained from an initial bleed, increasing to 100 ml from subsequent bleeds. Advantages of the method include reliability, minimal trauma to the animal, and little contamination of the sample.

"Needle freaks": compulsive self-injection by drug users.

The compulsive use of hypodermic needles as an end in itself is illustrated two case reports. The author explains this behavior in terms of conditioning theory and psychodynamics and explores the possibilities for treatment. He notes that needle use is in many cases an important component in addiction to narcotics, a component whose significance should be recognized by those engaged in the treatment of addiction.

Apparatus for continuous flow mixing of explosive gases

The apparatus is based on the use of hypodermic needles and small diameter tubes as the primary metering elements. In order to assure reliability of operation three conditions must be satisfied: the flow choked at the tube exit, the friction coefficient maintained strictly laminar, and the gas behaving as a continuum. Construction of the apparatus, with proper consideration of the above conditions and their experimental verification, is presented.

The Use of Hypodermic Needles as Critical Orifices in Air Sampling

Hypodermic needles are useful as convenient low-cost critical orifices to control the flow rate in air sampling. Variations in flow rate were less than five per cent for 41 needle gauge-length combinations. To provide maximum accuracy, a simple calibration procedure is described. Needles may be reused more than six times, if protected. Types of protectors are described. Resistances of protector, collector, and prefilter combinations affect criticality at nine liters/min. Simple sampling devices using needles as orifices are described.

Psychodynamic reactions of children to the use of hypodermic needles; a study in the contrast of uncontrolled and self-controlled emotions.

The object of this investigation is the study of the different attitudes and responses of children to the use of needles. The designation hypodermic is chosen in this context to include needles between the gauges of 26 and 19, regardless of whether they were used for intracutaneous, subcutaneous, or intramuscular injection. In not considering size of instrument or route of administration, the whole emphasis of the inquiry as to emotional response was centered on what may be termed the symbol and the substance of cold steel. Anyone familar with the methods of preventive medicine as well as with the techniques of parenteral medication has had the experience over and over again, first, that children in varying age groups react differently to the threat of the needle and, second, that persons in the same age group manifest a wide range of psychodynamic response. The advantage of using these more-or-less

Techniques for Studies of Hemoglobin Synthesis in Daphnia

A new spectrochemical technique for determination of hemoglobin content in pale as well as red Daphnia has been presented. By use of this method the primary stimulus for hemoglobin synthesis of low dissolved oxygen content in the culture water has been confirmed. Spectral-Transmittance curves of Daphnia hemoglobin are figured and compared to those of rabbit hemoglobin. A method for controlling the oxygen level in culture flasks by the use of hypodermic needles and air tight rubber caps is described. A first approximation toward a semisynthetic medium for Daphnia is discussed.
