The activity of a crude extract formulation was evaluated in experimental amoebic liver abscess in golden hamsters and in immunomodulation studies. The formulation comprises the following five plants-Boerhavia diffusa, Tinospora cordifolia, Berberis aristata, Terminalia chebula and Zingiber officinale. The formulation had a maximum cure rate of 73% at a dose of 800 mg/kg/day in hepatic amoebiasis reducing the average degree of infection (ADI) to 1.3 as compared to 4.2 for sham-treated controls.
Ageing in immune reactivity is described at the level of lymphoid cells, at that of lymphoid organs and organ function, and at that of regulation of cell and organ function. Apart from shifts in numbers of lymphoid cell subpopulations, the decrease in communication capacity between lymphoid cell populations and in binding of invaders (like bacteria) is an important aspect of ageing. These aspects may contribute to the decreased immune reactivity to invaders and the enhanced incidence of immune reactions to self-components (autoimmune reactivity).
Long-standing beliefs about the ill-effects of mild to moderate obesity have been called into question by recent epidemiological studies and by critical review of older studies. A review of these studies reveals that the effects of obesity on health and longevity is more complex than we had realized. An attempt is made to throw light on this relationship by reviewing the large number of laboratory studies on nutrition, aging and obesity. The first series of such studies showed that restriction of food intake, beginning early in life, greatly increased longevity.
OBJECTIVE: Stress enhanced allergic skin wheal responses and allergen-specific IgE production. In contrast, mothers' kissing caused relaxation in infants, and kissing by lovers or spouses to atopic patients reduced allergic skin wheal responses. I studied the effect of kissing on production of allergen-specific IgE and cytokines in atopic patients. METHODS: Twenty-four patients with mild atopic eczema and 24 patients with mild allergic rhinitis kissed with lovers or spouses freely for 30 min while listening to soft music.

The effects of self-hypnosis training on immune function and mood were examined in medical students at exam time. Hypnosis involved relaxation and imagery directed at improved immune function and increased energy, alertness and concentration. Hypotheses were made about activated and withdrawn personality differences. Eight high and eight low hypnotically susceptible participants were given 10 sessions of hypnosis, one live and nine tape-recorded, and were compared with control subjects (N=12). CD3, CD4, CD8, CD19 and CD56 NK cells and blood cortisol were assayed. Life-style, activated vs.

Four important investigations were reported during the latter part of 2001. All address the biological impact of hypnotic interventions. Three of these studies focus specifically on if and how hypnotic interventions affect immune functions. A range of immune assays is employed, from allergic response to blood-based assays of immune functioning during nonlaboratory periods of stress. In all 3 cases, measurable shifts in immune functioning are associated with hypnotic interventions.
The immunobiological activity was investigated of certain medicinal plants widely used in the Ayurvedic and Unani systems of medicine for treatment of chronic infections and immunological disorders. The effect of an ethanolic extract of each drug was studied on delayed type hypersensitivity, humoral responses to sheep red blood cells, skin allograft rejection, and phagocytic activity of the reticuloendothelial system in mice. Picrorhiza kurroa was found to be a potent immunostimulant, stimulating both cell-mediated and humoral immunity.
Immunomodulatory activity of aqueous extract of Trigonella foenum graecum L., a widely used medicinal and dietary herb, was evaluated in male Swiss albino mice. Mice were treated with three doses of extract (50, 100 and 250 mg/kg body weight per os) for 10 days. Body weight, relative organ weight, cellularity of lymphoid organs, delayed type of hypersensitivity (DTH) response, plaque-forming cell (PFC) assay, haemagglutination titre (HT), quantitative haemolysis of SRBC (QHS) assay, phagocytosis, and lymphoproliferation were studied in various groups of animals.
Lagenaria siceraria (Mol.) Standley fruit (bottle gourd), a commonly used vegetable in India is described as cardiotonic and as a general tonic in Ayurveda. Keeping in view the presence of free radical scavenging activity in L. siceraria and involvement of free radicals in the development of various disorders, present studies were designed to evaluate the ethanolic extract of L. siceraria fruit against the disorders where free radicals play a major role in pathogenesis.
