Lepromatous leprosy patients experiencing erythema nodosum lepro­ sum (ENL) have been reported to have an increase in the ratio of circulating T -helper to T -suppressor cel ls ( H : S ratio) . Thal idomide is an effect ive drug in the management of ENL . To determine if thal idomide affected cells of the immunoregulatory system, B cel ls , T cel ls , T-suppressor cel ls , T-helper and natural ...

Objective(s):In this study, the serum level of interferon-γ (IFN- γ) and interlukin-4 (IL-4) was evaluated as a marker of Th1 and Th2 immune response that influence the clinical course of cutaneous leishmaniasis[r1] . Materials and Methods: This cross-sectional study was conducted on 44 cases of cutaneous leishmaniasis (21 cases with healed lesions and 23 cases with chronic non-healing lesions...

Since 1 965 , thal idomide has been used in a l leviat ing the signs and symptoms of a major medical complicat ion of lepromatous leprosy, erythema nodosum lepro­ sum (EN L) . I H istologically, the hal lmarks of E N L lesions are vascul i t i s or vascular necrosis , oedema and inflammation with infil trates of neutrophi l s affect ing the entire dermis and subcutaneous fat . 2 The factor or f...

background and objectives: infection with human immunodeficiency virus (hiv) results in dysregulation of the cytokine profile. a switch from a t helper 1 (th1) to a th2 cytokine has been proposed as an important factor in progression of hiv infection to aids. the aim of the present study was to assess the level of th1 and th2 cytokines in hiv infected individuals in order to identify the switch...

sugar beet pulp is one of the sugar industries by-products which can be used for cellulase enzyme production, enzymatic saccharification, and alcohol production due to its high percentage of lingo-cellulosic content. trichoderma spp. is an important fungus that produces a wide range of cellulytic enzymes. in this study, cellulase enzyme was produced by placing sugar beet pulp in trichoderma fer...

CEL-1000 (DGQEEKAGVVSTGLIGGG) is a novel potential preventative and therapeutic agent. We report that CEL-1000 confers a high degree of protection against Plasmodium sporozoite challenge in a murine model of malaria, as shown by the total absence of blood stage infection following challenge with 100 sporozoites (100% protection) and by a substantial reduction (400-fold) of liver stage parasite ...

interleukin-4 (il-4) is produced by t-helper cells type 2 (th2) and induces ige synthesis. t-helper cells type 1 (th1) produce interferon-gamma (ifn-gamma) which suppresses th2 and reduces il-4 induced ige production. in this :;tudy , we demonstrated that the levels of specific ige in the serum of atopic children (n=20) were elevated while il-4 production was increased and ifn-gamma secretion w...

the cd30 antigen seems to play a costimulatory role in maintaining the physiological balance between t-helper (th)1/th2 immune responses. in this study, plasma and in vitro soluble cd30 (scd30) secretion was investigated in patients with coronary artery disease (cad) as a plausible marker of dysregulated immune response. twenty one patients with angiographically confirmed cad and 31 healthy con...
