Pro-opiocortin peptides in rat cerebrospinal fluid

Cerebrospinal fluid (CSF) taken from rats implanted with chronic cisternal cannulae was subjected to gel filtration chromatography on Sephadex G-50. Fractions were monitored using radioimmunoassays for N-terminal pro-opiocortin (N-POC), gamma 3-melanotropin (gamma 3-MSH), C-terminal adrenocorticotropin (C-ACTH), alpha-endorphin, beta-endorphin, gamma-lipotropin (gamma-LPH) and alpha-MSH. Two peaks which corresponded in elution position to rat N-POC (1-74) and gamma 3-MSH were detected. The major C-ACTH-immunoreactive (IR) peak was found to correspond to 14k ACTH. While no alpha-endorphin immunoreactivity was detected in rat CSF, three beta-endorphin-IR peaks were identified in positions expected for beta-LPH, beta-endorphin (1-31) and beta-endorphin (1-27), as well as a major peak of activity with the elution characteristics and cross-reactivity of rat gamma-LPH. HPLC of the alpha-MSH-IR material in rat CSF revealed the presence of a major peak of immunoreactivity whose retention time did not correspond to the known oxidised and reduced forms of alpha-MSH and its desacetylated and diacetylated derivatives. The identity of this peak is unknown.     

The use of zootherapeutics in folk veterinary medicine in the district of Cubati, Paraíba State, Brazil

Background

Viewed through the micro focus of an interpretive lens, medical anthropology remains mystified because interpretivist explanations seriously downplay the given context in which individual health seeking-behaviours occur. This paper draws upon both the interpretivist and political economy perspectives to reflect on the ethno medical practices within the Korean-Australian community in Sydney.

Methods

We draw on research data collected between 1995 and 1997 for an earlier study of the use of biomedical and traditional medicine by Korean-Australians in Sydney. A total of 120 interviews were conducted with a range of participants, including biomedical doctors, traditional health professionals, Korean community leaders and Korean migrants representing a range of socio-economic backgrounds and migration patterns.

Results and Discussion

First, the paper highlights the extent to which the social location of migrants in a host society alters or restructures their initial cultural practices they bring with them. Second, taking hanbang medicine in the Korean-Australian community as an illustrative case, the paper explores the transformation of the dominant biomedicine in Australia as a result of the influx of ethnomedicine in the era of global capitalism and global movement.

Conclusion

In seeking to explain the popularity and supply of alternative health care, it is important to go beyond the culture of each kind of health care itself and to take into consideration the changes occurring at societal, national and global levels as well as consequential individual response to the changes. New social conditions influence the choice of health care methods, including herbal/alternative medicine, health foods and what are often called New Age therapies.     

Impact of psychosocial factors on quality of life in overweight youth

Objective: The psychosocial functioning of overweight youth is a growing concern. Research has shown that overweight children report lower quality of life (QOL) than their non‐overweight peers. This study sought to extend the literature by examining the association between peer victimization, child depressive symptoms, parent distress, and health‐related QOL in overweight youth. Mediator models are used to assess the effect of child depressive symptoms on the relationship between psychosocial variables and QOL. Research Methods and Procedures: The sample consisted of 96 overweight and at‐risk‐for‐overweight children (mean age = 12.8 years) and their parents who were recruited from a Pediatric Endocrinology Obesity Clinic. Parents completed a demographic questionnaire, the Pediatric Quality of Life Inventory–parent‐proxy version, and the Brief Symptom Inventory. Children completed the Children's Depression Inventory–Short Form, the Schwartz Peer Victimization Scale, and the Pediatric Quality of Life Inventory. Results: Increased parent distress, child depressive symptoms, and peer victimization were associated with lower QOL by both parent‐proxy and self‐report. Child depressive symptoms mediated the relationship between psychosocial variables (parent distress and peer victimization) for self‐reported QOL but not for parent‐proxy‐reported QOL. Discussion: This study documented the important impact of peer victimization and parental distress on the QOL of overweight children. Expanding our understanding of how overweight children experience and interact with their environment is critical. Further research is needed to examine the mechanisms by which parent distress and peer victimization impact the development of depressive symptoms in overweight children, including coping and support strategies that may buffer these children against the development of depressive symptoms and ultimately lower QOL.     

Evaluation of the prevalence and economic burden of adverse drug reactions presenting to the medical emergency department of a tertiary referral centre: a prospective study

Background  

Adverse drug reactions (ADRs) are now recognized as an important cause of hospital admissions, with a proportion ranging from 0.9–7.9%. They also constitute a significant economic burden. We thus aimed at determining the prevalence and the economic burden of ADRs presenting to Medical Emergency Department (ED) of a tertiary referral center in India
