Special aspects of social support: Qualitative analysis of oncologic rehabilitation through a belly dancing peer support group.

Tumour-related peer support groups (PSGs) show long-term development in quality of life and coping, and decrease distress in cancer care. To clarify channels of social support in oncologic rehabilitation by combined exercise and psychosocial therapy, individual semi-structured interviews were conducted after 1 year additional belly dance rehabilitation in a closed PSG among 51 patients with malignant tumour diagnosis in Budapest, Hungary. Interview data were transcribed and analysed using qualitative content analysis (ATLAS.ti 6 Win). Results suggest that group experience provides emotional-, practical- and informational support. We could point out specific social effects of "role model" function and extend the coping model. The group dispose all the features of effective suggestion and may be effectively applied as additional therapy for patients with malignancies. The extended coping model and the introduction of "role model" function could be useful for PSGs' efficacy assessment.

Effects of systemic PACAP treatment in monosodium glutamate-induced behavioral changes and retinal degeneration.

The present article investigated effects of systemic pituitary adenylate cyclase-activating polypeptide (PACAP) treatment in monosodium glutamate (MSG)-induced retinal degeneration and neurobehavioral alterations in neonatal rats. It was found that the dose of PACAP that effectively enhances neurobehavioral development in normal rats was able to counteract the retarding effect of MSG on righting, forelimb placing, and grasp reflexes and caused a significant amelioration of the righting and gait reflex performance and motor coordination at 2 weeks of age. In the retina, significant amelioration of neuronal loss in the inner retinal layers was achieved, but it was much less than that observed by local administration.

Development of neurological reflexes and motor coordination in rats neonatally treated with monosodium glutamate.

Monosodium glutamate (MSG) treatment of neonatal rats causes neuronal degeneration in various brain areas and leads to several neurochemical, endocrinological and behavioral alterations. However, relatively little is known about the development of neurological reflexes and motor coordination of these animals. Therefore, the aim of the present study was to examine the neurobehavioral development of newborn rats treated with MSG. Rats received MSG at postnatal days 1, 3, 5, 7, and 9. Appearance of neural reflexes and reflex performance as well as motor coordination were examined for 5 weeks after birth. The efficacy of MSG treatment was confirmed by histological examination of the arcuate nucleus. We found that MSG treatment delayed the appearance of forelimb placing, forelimb grasp and righting reflexes, besides the retarded somatic development. The treated pups performed surface righting in significantly longer times. Also, worse performance was observed in the foot-fault and rota-rod tests. However, MSG-treated rats reached control levels by the end of the fifth postnatal week. These results show that MSG treatment does not cause permanent alterations in the neurobehavioral development, only delays the appearance of some reflexes and leads to temporary changes in reflex performance and motor coordination signs.

Effects of electrical stunning frequency and voltage combinations on the presence of engorged blood vessels in goose liver.

The purpose of this study was to investigate the influence of nine electrical stunning methods using various frequency and voltage combinations on the occurrence of engorged blood vessels in goose liver. Two hundred seventy Gourmaud geese (liver-type line SI 14) were slaughtered at 12 wk of age, in groups of 90 at three different times. Thirty birds each were subjected to one of the nine stunning methods. Neck cutting was performed immediately after stunning. The duration of exsanguination was 11 min. After completion of bleeding, the birds were scalded, defeathered manually, and kept refrigerated. At 1 d postmortem, the carcasses were eviscerated and cut up. From the slaughterhouse, the livers chilled in ice were transported to the cannery where they were weighed and graded at 2 d postmortem and were further processed. All of the veins and capillaries full of blood were removed from livers, because their presence was a hazard to product quality by causing discoloration of the canned liver, and the percentage of liver weight loss was then determined. The loss in liver weight due to removal of engorged blood vessels was reduced (P < 0.05) at 350 Hz, 70 to 90 V, and 80 to 85 mA when compared to the results obtained with any other stunning method tested. It was concluded that the use of high-frequency currents for electrical stunning of liver geese might have considerable commercial advantages.

Interrelationships between the gastric secretory responses, prostaglandin E2 inhibition and serum level of immunoreactive gastrin in pylorus-ligated and antrectomized rats.

The effects of prostaglandin E2 (PGE2) have been studied on the gastric secretion and the serum level of immunoreactive gastrin in pylorus-ligated and antrectomized rats. It has been observed that: (1) a significant inhibition of gastric secretion (volume and acid output) was caused by PGE2, applied in doses of 75, 150 and 300 microgram/kg body weight, subcutaneously, in both pylorus-occluded and antrectomized rats: PGE2 inhibition of gastric secretion was more pronounced in rats with antrectomy; (2) no significant changes were found in the serum gastrin levels of both pylorus-ligated and antrectomized rats, and (3) no significant changes in serum levels of immunoreactive gastrin were produced by different doses of PGE2, in comparison with their marked inhibitory effects on gastric H+ secretion. It was concluded that there is no essential role of the immunoreactive gastrin, originated from the antral part of the stomach, neither in development of gastric hypersecretion nor in PGE2-produced inhibition on gastric secretion of the pylorus-occluded rats.

99-m technetium (Dupont Cardiolite) investigations in postinfarction patients with Holter-checked silent ischaemia.

Sixteen middle-aged, normotensive, slightly overweight male patients with previous myocardial infarction were studied during Holter-checked silent myocardial ischaemia. As reference, stress and late 201-T1 scintigraphy served for comparison with Cardiolite-MIBI silent ischaemic perfusion scan, both carried out in planar mode. The circumferential profiles differed in 9 cases, on region of interest basis the segment number difference was 10, but the late distribution segment number was near to both ischaemic numbers. The quantitative scores were distinctive (ratio 133-128/103) indicating the silent ischaemia appeared in the peri-infarct area. The silent ischaemic MIBI and stress 201-T1 ischaemic score difference was reduced by means of repeated SPECT investigation. With gated radionuclide ventriculography there was -4.3% difference between the left ventricular ejection fractions, measured with first pass MIBI technique during silent ischaemia and afterwards in basal state. The impairment of the left ventricular function was reflected on the stroke pattern of our Holter-based radiocyclogram, as well. Taking the 43.7-48.0 = -4.3% "ischaemic shift" into consideration it was a close correlation (r = 0.90) between the two kinds of ejection fraction determination. The major rhythm failures (occurring during the 24 h Holter monitoring) decreased to a higher degree the left ventricular ejection fraction than silent ischaemia or silent ischaemia and minor rhythm failure together (38-42-50%).
