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.
Immune activation is an effective as well as protective approach against emerging infectious diseases. The immunomodulatory activities of Triphala (Terminalia chebula, Terminalia belerica and Emblica officinalis) were assessed by testing the various neutrophil functions like adherence, phagocytosis (phagocytic index (P.I) and avidity index (A.I)) and nitro blue tetrazolium (NBT) reduction in albino rats. In recent years much attention is being focused on the immunological changes occur during stress. Noise (100 dB) stress for 4 h/d for 15 d, was employed to alter the neutrophil functions.
BACKGROUND: Lifespan extension is achieved through long-term application of dietary restriction (DR), and benefits of short-term dietary restriction on acute stress and inflammation have been observed. So far, the effects of short-term DR in humans are relatively unknown. We hypothesized that short-term DR in humans reduces the acute phase response following a well defined surgical trauma. METHODS: Thirty live kidney donors were randomized between 30% preoperative dietary restriction followed by 1 d of fasting (n=17) or a 4 d ad libitum regimen (n=13) prior to surgery.
OBJECTIVES: To assess whether familial longevity can be attributed to sustained hematopoietic capacity. DESIGN: Prospective follow-up study of two independent population-based cohorts. SETTING: The Leiden Longevity Study and the Leiden 85-plus Study. PARTICIPANTS: From the Leiden Longevity Study, 1,001 nonagenarians with familial longevity were included. As age-matched controls, 260 nonagenarians without familial longevity were used from the Leiden 85-plus Study. MEASUREMENTS: Hemoglobin, leukocytes, and thrombocytes were measured for all subjects with and without familial longevity.
Although the overproduction of immunoglobulins by short-lived plasma cells accompanying an immune response links with their apoptosis, how long-lived plasma cells adapt to ensure their longevity in this context is obscure. Here, we show that apoptosis signal-regulating kinase 1 (ASK1) contributes to apoptosis of plasma cells because ASK1 activity was induced during differentiation of short-lived plasma cells, and, when produced by ASK1-deficient mice, these cells survived better than those of control mice.
Six patients with various forms of leukaemia had neurological signs and symptoms associated with an extremely high white blood cell count and increased whole blood (but not plasma) viscosity. All were treated by leucapheresis with an Aminco Celltrifuge. Rapid and complete reversal of all symptoms occurred in three patients and partial recovery in one. One patient died shortly after leucapheresis and another (from cerebral intravascular coagulation) two days later.
Eight patients with E. coli septicaemia had oliguric renal failure which was associated with haematological evidence of intravascular coagulation. Five of these patients also had the characteristic blood picture of microangiopathic haemolytic anaemia. In an attempt to prevent further deposition of fibrin, intravenous heparin was administered to six patients, three of whom recovered fully and three died. The diagnosis of intravascular coagulation was subsequently confirmed by histological examination of necropsy material and it is suggested that some of the complications of E.
The inflammatory response was studied in patients with primary polycythaemia by means of a modified skin window technique. In untreated patients, the overall cellularity was a prominent feature and, as compared with the controls, the 48 h preparations showed a significantly greater percentage of granulocytes with a corresponding decreased percentage of macrophages. In the peripheral blood of these patients, both total white cells and granulocyte counts were significantly higher than in the control subjects.
DNA methylation, which is the transference of a methyl group to the 5'-carbon position of the cytosine in a CpG dinucleotide, is one of the major mechanisms of epigenetic modifications. A number of studies have demonstrated altered DNA methylation of peripheral blood cells in schizophrenia (SCZ) in previous studies.
