Social reform versus education reform: university nursing education in Canada, 1919-1960.

Nurses' struggle to attain educational parity with other professional groups is closely aligned with the struggle of women for social equality within Canadian institutions. The attempts of nursing educators to shift their perspective from social reform to educational reform and to develop nursing scholarship has been restricted by the cultural views of women. Consequently, nurses' gains in attaining higher education have been realized by reforms in social and health care policies thought suitable for women.

The influence of growth hormone injections on the endocrine and metabolic status of gilts.

Twelve Yorkshire x Landrace prepubertal gilts were assigned equally to treatments involving daily injections of either porcine growth hormone (GH, 90 micrograms/kg) or vehicle buffer from 150 to 159 d of age. Blood samples were obtained every hour from 0600 hr at 153 d until 0500 hr at 154 d of age, inclusively. At 0800 hr on 154 d, gilts received an injection of 500 IU PMSG, followed 96 hr later by 250 IU hCG.

Phase II trial of spirogermanium and vindesine in malignant glioma.

Fifty-four adults with recurrent malignant glioma were treated on an Eastern Cooperative Oncology Group (ECOG) trial. All had previous radiation therapy, and 70% had previous chemotherapy. They were assigned to either vindesine 3 mg/m2 weekly or spirogermanium 80 mg/m2 three times weekly with escalation to 120 mg/m2.

The influence of exogenous pituitary growth hormone on the ovulatory response to PMSG and hCG and the LH response to estradiol benzoate in prepubertal gilts.

Two experiments were performed to examine the influence of exogenous growth hormone on the reproductive axis in gilts. Experiment one employed 26 Yorkshire X Landrace prepubertal gilts, which were selected at 150 d and 86.5 +/- 1.

The influence of premating feed intake on the reproductive performance of gilts.

In an attempt to improve the reproductive performance of gilts mated at puberty, 70 Yorkshire x Landrace gilts were allocated at 120 d of age and 60 kg body weight to one of two treatments. Restricted gilts were fed 2.0 kg d-1 of a diet formulated to provide 18% crude protein and 14.

Catheter drainage of symptomatic postoperative mediastinal effusion guided by computed tomography. A nonoperative approach.

Postoperative mediastinal effusion after cardiac operations is a common phenomenon and has a potential for serious complications, such as tamponade necessitating urgent drainage. Computed tomography of the chest provides excellent postoperative visualization of the mediastinum. Catheter insertion or paracentesis guided by computed tomography has been used to accomplish nonoperative drainage of symptomatic postoperative mediastinal effusion in six cases.

Energy intake, body composition and reproductive performance of the gilt.

The relationship between age, live weight, body composition and energy status on the onset and maintenance of reproductive activity in females is reviewed. When possible, swine studies have been employed, although, of necessity, much data are drawn from other species. The relationship between age, weight and puberty is controversial.

Nutrition and sow prolificacy.

Prolificacy has been defined as the number of viable piglets produced per year or per breeding lifetime. Prolificacy is influenced by age at first successful mating, ovulation rate and embryo survival at each mating, number of live born, viable pigs and the sow's ability to be successfully remated at regular intervals. It is concluded that under normal conditions of feeding and management nutrition will have a minimal influence on gilt prolificacy.

Effects of oestradiol benzoate treatment on the reproductive performance and endocrine status of sows after lactations of 10 or 35 days.

Forty-two Landrace X Large White sows were used in 3 studies of oestradiol benzoate treatment 24 h (E1) or 48 h (E2) after piglet removal, following lactations of 10 (S) or 35 (L) days, or were untreated controls (C). For Exp. 1, oestradiol benzoate doses were 4, 16 and 64 micrograms/kg body weight; since highest mean LH peaks followed use of the 16 micrograms/kg dose, this treatment was used in later studies.

Plasma concentrations of LH, prolactin, oestradiol-17 beta and progesterone in sows weaned after lactation for 10 or 35 days.

Piglets were weaned from multiparous sows at 10 days (Group E; N = 7) or 35 days (Group C; N = 8) of lactation. Blood samples were collected at 8 h intervals from the day before weaning (Day--1) until and including the day of first mating, then once daily until 10 days post coitum. Additionally, 5 sows in each group were sampled at 30 min intervals for 12 h on Days--1, 0 and 1, then at 30 min intervals for 6 h daily until mating, finally at 30 min intervals for 2 h daily until 5 days post coitum.

Telescopic laryngoscopy.

Examination of the larynx is neglected as a regular part of the physical examination by many physicians, largely because of difficulties inherent in the angled-mirror technique of visualizing this area. Simple, relatively inexpensive right-angle telescopes especially designed for laryngoscopy are now available to facilitate this examination. In one study, abnormalities were found in 17 percent of consecutive asymptomatic patients receiving laryngoscopy.

Influence of boar contact on attainment of puberty in gilts after removal of the olfactory bulbs.

At 6-7 weeks of age the olfactory bulbs were removed from gilts which were then exposed to vasectomized boars for 30 min/day, starting on Day 160. Mean +/- s.e.

The conjunctival goblet cell in pterygium formation.

Histological studies of pterygium pathology, reveals the presence of goblet cells liberally distributed throughout the epithelial surface. This feature poses medical and surgical implications which are discussed.

Initial clinical evaluation of the Hospal artificial kidney system.

A high flux artificial kidney system, which permits control over ultrafiltration, has been developed and patients are now being treated with it at a large outpatient kidney center. The basic operating characteristics have been described and some preliminary clinical results mentioned. Characteristics of the Hospital Artificial Kidney System are: 1.

High Rates of controlled ultrafiltration combined with optimal diffusion: recent advances in hemodialysis technique.

A system which permits high rates of middle molecule removal while preserving the removal of low molecular weight substances is described. It consists of a high fluid flux hollow fiber artificial kidney and an ultrafiltration controller. When used in combination, high rates of convective transport can be achieved through rapid ultrafiltration and reconstitution of blood with physiologic salt solutions.

An integrated medical record and data system for primary care. Part 7: the encounter form: problems and prospects for a universal type.

The importance of an encounter form for recording ambulatory patient information is stressed. Certain problems surrounding appropriate definition of the minimum basic data set (MBDS) are discussed as is the potential development of a uniform encounter form which would cover diagnostic information as well as items necessary for insurance companies and internal practice management.
