A Schistosoma mansoni cercarial antigen preparation (cercarial transformation fluid--SmCTF) was evaluated for detection of anti-schistosome antibodies in human sera in 4 collaborating laboratories. The performance of SmCTF was compared with that of S. mansoni egg antigens (SmSEA) in an indirect enzyme-immunoassay (ELISA) antigen assay, the latter being used routinely in 3 of the 4 participating...

In the present study, the efficacy of 6 different species of medicinal plants belonging to 5 different families against Biomphalaria alexandrina snails and Schistosoma mansoni stages were examined. During screening test of water suspension and methanol extract, results revealed that Oreopanax reticulatum (Family: Araliaceae) had the strongest molluscicidal activity against Biomphalaria alexandr...

Bone marrow (BM) cells from BALB/c mice infected with mixed-sex Schistosoma mansoni cercariae were assessed for their capacity to form in vitro colony forming units of erythroid (CFU-e) and granulocyte/macrophage (CFU-c) cells. At four weeks after infection, substantial BM commitment to granulopoiesis was noted by an increase in CFU-c, with no changes in CFU-e. Elevated marrow granulopoietic ac...

Parthenium dermatitis is an immuno-inflammatory disease caused by Parthenium hysterophorus and is the commonest cause of plant dermatitis in India. It is caused by airborne dry and friable plant particles including trichomes, and the most important allergens responsible for allergic contact dermatitis are sesquiterpene lactones. The combined type IV and type I hypersensitivity to parthenium has...

BACKGROUND A chronic dermatosis like nummular dermatitis may be complicated by contact dermatitis due to an impaired cutaneous barrier. This study is aimed at evaluating secondary contact dermatitis in patients with nummular dermatitis. METHODS Patch testing with the Indian Standard Series was performed in 50 of 78 patients with a clinical diagnosis of nummular eczema. Significant reactions w...

Background: This two-arm, randomized clinical study aimed to compare efficacy between topical Alpha ointment and topical hydrocortisone cream (1%) in the healing of radiation-induced dermatitis in breast cancer patients. Methods: The inclusion criteria comprised newly pathologically proven, locally advanced breast cancer (treated with modified radical mastectomy followed by sequential adjuvant ...

Advances in knowledge of neurocellulars relations have provided new directions in the understanding and treatment of numerous conditions, including atopic dermatitis. It is known that emotional, physical, chemical or biological stimuli can generate more accentuated responses in atopic patients than in non-atopic individuals; however, the complex network of control covered by these influences, e...

Background: Hypofractionated radiotherapy (HF) method was introduced to overcome the quickly growing tumor cells as well as shortening whole treatment course in solid tumors such as breast cancers. Here, we compared the incidence of dermatitis and pharyngitis among patients undergoing HF versus conventional fractionationated (CF) radiation therapy following surgery for breast cancer. Methods: ...

Cercarial penetration, in low to moderate numbers, does not cause a normal skin inflammatory response; therefore, the authors sought to determine whether cercariae can down-regulate keratinocyte activation and thus the secretion of pro-inflammatory cytokines and eicosanoids. Human living skin equivalent (LSE, Organogenesis) consisting of dermal, epidermal and stratum corneum-like layers was use...
