Chinese medicine and biomodulation in cancer patients—Part one

Traditional Chinese Medicine (tcm) may be integrated with conventional Western medicine to enhance the care of patients with cancer. Although tcm is normally implemented as a whole system, recent reductionist research suggests mechanisms for the effects of acupuncture, herbs, and nutrition within the scientific model of biomedicine. The health model of Chinese medicine accommodates physical and pharmacologic interventions within the framework of a body–mind network. A Cartesian split does not occur within this model, but to allow for scientific exploration within the restrictions of positivism, reductionism, and controls for confounding factors, the components must necessarily be separated. Still, whole-systems research is important to evaluate effectiveness when applying the full model in clinical practice. Scientific analysis provides a mechanistic understanding of the processes that will improve the design of clinical studies and enhance safety. Enough preliminary evidence is available to encourage quality clinical trials to evaluate the efficacy of integrating tcm into Western cancer care

Research and Regulatory Issues for Integrative Oncology

Many oncology patients are empowering themselves to self-treat with herbs, nutritional supplements, and mind–body techniques. Other practitioners, such as acupuncturists, are becoming involved in the supportive care of cancer patients. Government research agencies are supporting studies that evaluate complementary therapies. This educational article provides an overview of the challenges in designing appropriate studies of complementary and alternative therapies, evaluating the results, and regulating implementation of useful therapies

Massage therapy for cancer patients: a reciprocal relationship between body and mind

Some cancer patients use therapeutic massage to reduce symptoms, improve coping, and enhance quality of life. Although a meta-analysis concludes that massage can confer short-term benefits in terms of psychological wellbeing and reduction of some symptoms, additional validated randomized controlled studies are necessary to determine specific indications for various types of therapeutic massage. In addition, mechanistic studies need to be conducted to discriminate the relative contributions of the therapist and of the reciprocal relationship between body and mind in the subject. Nuclear magnetic resonance techniques can be used to capture dynamic in vivo responses to biomechanical signals induced by massage of myofascial tissue. The relationship of myofascial communication systems (called “meridians”) to activity in the subcortical central nervous system can be evaluated. Understanding this relationship has important implications for symptom control in cancer patients, because it opens up new research avenues that link self-reported pain with the subjective quality of suffering. The reciprocal body–mind relationship is an important target for manipulation therapies that can reduce suffering

Natural health products that inhibit angiogenesis: a potential source for investigational new agents to treat cancer—Part 2

The herbalist has access to hundreds of years of observational data on the anticancer activity of many herbs. Laboratory studies are expanding the clinical knowledge that is already documented in traditional texts. The herbs that are traditionally used for anti-cancer treatment and that are anti-angiogenic through multiple interdependent processes (including effects on gene expression, signal processing, and enzyme activities) include Artemisia annua (Chinese wormwood), Viscum album (European mistletoe), Curcuma longa (curcumin), Scutellaria baicalensis (Chinese skullcap), resveratrol and proanthocyanidin (grape seed extract), Magnolia officinalis (Chinese magnolia tree), Camellia sinensis (green tea), Ginkgo biloba, quercetin, Poria cocos, Zingiber officinalis (ginger), Panax ginseng, Rabdosia rubescens hora (Rabdosia), and Chinese destagnation herbs. Natural health products target molecular pathways other than angiogenesis, including epidermal growth factor receptor, the HER2/neu gene, the cyclo-oxygenase-2 enzyme, the nuclear factor kappa-B transcription factor, the protein kinases, the Bcl-2 protein, and coagulation pathways. Quality assurance of appropriate extracts is essential prior to embarking upon clinical trials. More data are required on dose–response, appropriate combinations, and potential toxicities. Given the multiple effects of these agents, their future use for cancer therapy probably lies in synergistic combinations. During active cancer therapy they should generally be evaluated in combination with chemotherapy and radiation. In this role, they act as modifiers of biologic response or as adaptogens, potentially enhancing the efficacy of the conventional therapies or reducing toxicity. Their effectiveness may be increased when multiple agents are used in optimal combinations. New designs for trials to demonstrate activity in human subjects are required. Although controlled trials may be preferable, smaller studies with appropriate endpoints and surrogate markers for anti-angiogenic response could help to prioritize agents for larger, resource-intensive phase iii trials

ALZHEIMERS DISEASE - HISTOLOGICAL ULTRASTRUCTURAL AND IMMUNOCHEMICAL STUDY OF AN AUTOPSY PROVEN CASE

We report a detailed morphological, ultrastructural and immunochemical features of neuronal pathology in a case of Alzheimer's disease. This is probably the first detailed study of an autopsy confirmed case from India. The features noted are similar to the ones described from the West

NEUROBIOLOGICAL CHARACTERIZATION OF BIPOLAR AFFECTIVE DISORDERS : A FOCUS ON TARDIVE DYSKINESIA AND SOFT NEUROLOGICAL SIGNS IN RELATION TO SERUM DOPAMINE BETA HYDROXYLASE ACTIVITY

In this study, the prognostic determinants were investigated involving bipolar patients classified into two groups-one with favourable course and outcome, and the other with clearly unfavourable prognosis, based on certain recommended criteria, with intermediate prognosis were excluded. As compared to the poor prognosis group, the good prognosis group had lower social dysfunctions, lower ratings on psychopathotogy fewer indicators of neurodysfunction in form of neurological soft signs (NSS) and tardive dyskinesia (TD). The poor prognosis group was characterized by: (i) older age at onset; (ii) more manic than depressive episodes (5:1) and (HI) lower levels of serum dopamine-β-hydroxylase activity (DBH). The association between poor prognosis bipolar disorder having neuroleptic intolerance (TD and NSS) with low serum DBH, suggests that it is genetically governed. Further research in this direction seems in order, particularly the follow up of first episode manic disorders
