Crataegus oxycantha (hawthorn) is used in herbal and homeopathic medicine as a cardiotonic. The present study was done to investigate the effect of the alcoholic extract of Crataegus oxycantha (AEC) on mitochondrial function during experimentally induced myocardial infarction in rat. AEC was administered orally to male albino rats (150-200 g), at a dosage of 0.5 ml/100 g body weight/day, for 30 days. At the end of the experimental period, the animals were administered isoproterenol (85 mg/kg body weight, s.c) for 2 days at an interval of 24 h. After 48 h, the rats were anaesthetized and sacrificed. The hearts were homogenized for biochemical and electron microscopic analysis. AEC pretreatment maintained mitochondrial antioxidant status, prevented mitochondrial lipid peroxidative damage and decrease in Kreb's cycle enzymes induced by isoproterenol in rat heart.

Tincture of Crataegus (TCR), an alcoholic extract of the berries of hawthorn (Crataegus oxycantha), is used in herbal and homeopathic medicine. The present study was done to investigate the protective effect of TCR on experimentally induced myocardial infarction in rats. Pretreatment of TCR, at a dose of 0.5 mL/100 g bodyweight per day, orally for 30 days, prevented the increase in lipid peroxidation and activity of marker enzymes observed in isoproterenol-induced rats (85 mg kg(-1) s. c. for 2 days at an interval of 24 h). TCR prevented the isoproterenol-induced decrease in antioxidant enzymes in the heart and increased the rate of ADP-stimulated oxygen uptake and respiratory coupling ratio. TCR protected against pathological changes induced by isoproterenol in rat heart. The results show that pretreatment with TCR may be useful in preventing the damage induced by isoproterenol in rat heart.

Background:Home-based palliative services form the cornerstone of Kerala's palliative program. However, two issues need research: (a) whether family-homes can be considered as the locus of ageing and dying for marginal populations who experience deprivation and poverty and (b) whether the present delivery structure meets the needs of elderly population. These issues are examined in the context of two rural areas. The study explores end-of-life characteristics of the elderly – their sociodemographic status and living patterns, morbidity profile, and functional status. It also looks into the accessibility and utilization of palliative services and respondents’ satisfaction with different components of the services.Materials and Methods:A descriptive cross-sectional survey design is used. Data were collected based on the interviews of sixty service users sampled randomly from a roster of palliative care services. Semi-structured interviews were substantiated by personal field observations.Results:The study has found people living under extreme financial distress with inadequate shelter and poor social security provisions. The health profile is characterized by high level of functional dependence. Many dependent widowed women were living alone without appropriate care and shelter. The palliative program as perceived by the respondents is characterized by few doctor visitations and poor frequency.Conclusion:The study concludes that home-based palliation in its present form does not promote good end-of-life care. It lacks an integrated approach with good service-mix. It raises serious questions on family-home as the locus of ageing and dying for marginal populations, and suggests need for restructuring of the palliative program.
