Lymphocytes number

At all dietary levels, there was no significant effect on survival, growth, histology, hemoglobin, hematocrit, or lymphocyte number however, serum thiocyanate levels increased in a dose-dependent manner... 

Studying nonspecific immnnity we noted the suppression of corresponding parameters of the immnne system. The phagocytic activity of neutrophils (FAN) was considerably decreased which could lead to the development of infection. After hemosorption the activation of the immune system was noted and a significant increase in CD3, CD4 and CD19 lymphocyte numbers were seen. The level of... 

DEPC-treated water should be used for all RNA preparation solutions, gloves should be worn at all times, and RNase-free tips and tubes used. It is not necessary to purify mRNA, since total RNA prepared from freshly isolated or even frozen (liquid nitrogen or-80°C) lymphocytes is pure enough to carry out the RT-PCR reactions. A number of commercial kits are now available for RNA isolation (e.g., Stratagene), and use of one of these is recommended. Alternatively the single-step guanidimum thiocyanate/phenol extraction method of Chomczynski and Sacchi (23), on which most kit protocols are based, should be employed. If the lymphocyte numbers are low (<5 x 106), carrier RNA (100 pg of 16S ribosomal RNA) can be added at the start of this procedure to aid recovery. The preparation ends with a precipitation step using isopropanol, and the RNA may stored at -20°C in this form until required. 

Rozen MG, Snyder CA. 1985. Protracted exposure of C57BL/6 mice to 300 ppm benzene depresses B-and T-lymphocyte numbers and mitogen responses. Evidence for thymic and bone marrow proliferation in response to the exposures. Toxicology 37 13-26. 

Diabetes is also known to impair immune response in humans (176) and animals, which may contribute to slow wound healing in diabetics. In streptozocin-induced diabetes in rats, a number of circulating T and B lymphocytes decreased with no effect on the number of circulating monocytes and neutrophils. In a study by Oon et al. (177), it was demonstrated that feeding evening primrose oil prevents a diabetes-induced fall in lymphocyte number that may have been mediated by increased production of PGEi in this group. 

Noncompartmental analysis to assess systemic effects in humans. The degree of systemic side effects can easily be measured for most inhalation drugs. This includes, for example, the change in plasma potassium levels [97,98] and increase in heart rate for beta-2-adrenergic drugs. Other parameters, such as lymphocyte numbers, the suppression of 24-hour urine cortisol [70,99] and 24-hour serum cortisol levels [100] (a more sensitive parameter) have been used for inhaled glucocorticoids. 

The consistent finding of low lymphocyte numbers, particularly TCD8-I- cells in patients with iron overload, regardless of the presence of the mutation, places lymphocytes as key players in the systemic regulation of iron overload. 

MHC background linked to normal lymphocyte numbers, not subjected to activation by infection or inflammation, neither iron overload nor iron deficiency will, in theory, develop (see Section 13.1). 

Probably due to the narrow interstitium of the lung, lymphocytes had been overlooked in this area for a long time. In the rabbit, Schwarz (1963) described oval to spindle-shaped lymphoid cells with plumpy projections. Holt et al. (1986) carefully isolated, quantified and characterised lymphocytes in the interstitium of the human lung. For the whole lung interstitium a total of about 10 lymphocytes were calculated, which is equivalent to the lymphocyte number in the circulating blood pool in humans. In the interstitium of the human lung natural killer cells (NK cells) have also been identified (Weissler et al. 1987). The lymphocytes in the interstitial pool of the rat revealed a subset composition different from that in the peripheral blood (Fliegert et al. 1995). 

The first child S.Y. was initially treated with a calf thymic hormone extract (tP1 Serono Laboratories) but this produced no response. Red cell transfusion therapy initially given weekly and then every fortnight was accompanied by improvement in lymphocyte numbers,... 

CM-T412 is a chimeric anti-CD4 mAb with a human IgGl. Treatment with cM-T412 in RA patients produced a dose-dependent reduction in circulating CD4 lymphocyte numbers that was protracted especially when given with concomitant methotrexate (62, 63). In open studies, clinical improvement was variable and, as with Campath-IH, did not correlate with peripheral blood CD4 lymphopenia. Three placebo-controlled trials in RA (62, 64, 65) failed to show significant clinical benefit although, similar to CD5-PLUS, the doses used in the placebo-controlled trials were lower than those used in open studies. 

Sequential analysis of paired peripheral blood and synovial fluid samples showed that after a single 50 mg dose of cM-T412, there was a severe CD4 lymphopenia and over 90% of the peripheral blood CD4 lymphocytes were coated with cM-T412. In contrast, there was no change in synovial fluid CD4 lymphocyte numbers and only 11% of synovial CD4 cells were coated with cM-T412. After five daily treatments with cM-T412, there was a small but statistic-... 

Fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) contributed significant insights into the pathogenesis of IPF and other ILDs but practical value is limited (2,147). Increases in polymorphonuclear leukocytes, mast cells, alveolar macrophages, and myriad cytokines are noted in BAL fluid from patients with IPF lymphocyte numbers are usually normal (147). However, BAL cell profiles in IPF do not predict prognosis or therapeutic responsiveness (147). We do not believe BAL cell counts have a role to stage or follow IPF.
