The purpose of this study is to examine the psychogenic factors involved in the allergies of children, and to determine the area in which the social worker can contribute to the treatment of allergic children. It is intended to define (a) the limitations of this area of function as well as the limitations of the doctor's function; (b) the ways in which the doctor and the social worker can work together in the interests of these children; and (c) some of the types and methods of treatment that the social worker can use in treating allergic children. Literature on the subject has been consulted; but the essential material of the study is derived from an analysis of cases. The study group is made up of seventy clinical cases, who have been receiving medical services over periods of from one month to two years. Eighteen of these cases have received, in addition, casework services for approximately the same period. Where there is more than one record concerning the same patient, all available material has been used. For all those cases referred to social workers, an adequate social history of the child's personality and family background is available, and for the remainder of the seventy cases use is made as far as possible of the limited information on the child's background. The age limits of the group are from birth to sixteen years of age. This study has resulted in four major conclusions. (1) Psychogenic elements in the allergies of children appear to be particularly evident. (2) Allergic disorders create additional family tensions, thereby hampering adequate treatment, as well as the general adjustment of the child concerned. (3) The present resources for the diagnosis and treatment of allergic children in Vancouver lack adequate means of dealing with the psychogenic elements in these illnesses. (4) The social worker is equipped to deal with the psychogenic elements in illness, and she can, therefore, play an important role in assisting with diagnosis and treatment. This study of the psychogenic factors of allergies in children helps to clarify the role that social work must play in an adequate treatment programme, and it indicates the need for further research into this particular area of allergic disorders both as regards prevention and treatment. / Arts, Faculty of / Social Work, School of / Graduate

Liverwort Frullania franciscana Howe was found high on the allergic test scale by J. Mitchell of the Medical School of the University of British Columbia and co-workers. Frullanolide was isolated from Frullania tamarisci by J.D. Connoly and by G. Oisson and his co-workers. The plant sample, collected in Oregon, was hand separated, confirmed, air dried and milled before the extractions were done. A Soxhlet extraction with ether and cold extractions with n-hexane and with ether were carried out. Ether is a better extraction solvent than n-hexane for cold extraction. Column chromatography was used for the separation of the extract based on gradient elution from silica gel or aluminum oxide. Non-polar hydro-carbon sesquiterpenes and other hydrocarbons usually were eluted first. Frullanolide then was eluted. Studies by thin layer chromatography on silica gel showed that none of the fractions was a pure component; therefore, further separations were done by thin layer chromatography and small-scale column chromatography. However, no satisfactory separation systems were found, except that frullanolide was isolated from the silica gel plate with cyclohexanel/ethyl acetate 80/20, Rf' = 25.8, which was very close to the reported value. An infrared spectrum of this was taken and used as supporting evidence. An infrared spectrum of the first fraction from an aluminum oxide column showed that this was a reasonably pure fraction of hydrocarbons. By gas chromatography, eleven components were found in this fraction, and the percentage of the major component was calculated to be 97% by weight. Nuclear magnetic resonance and infrared spectra showed an exo-double bond with a 6-membered ring or larger. (I.R. : 3080 cm-1 ,1643 cm-1 ,888 cm-1, NMR δ 4.73) This fraction was then studied by means of a gas chr0matography-mass spectrometer, and the molecular weight of the main component of this fraction was 204. Kovats’ indices of the main component were taken by co-injection with 0-cedrene and ᵝ-bourbonene; these data, however, did not match any of the compounds listed. Infrared analysis of the other fractions from the columns and from thin layer chromatography showed the presence of carbonyl groups. One of the carbonyl groups absorbed at about 1770 cm-1, characteristic of a y -lactone.
