| neurological manifestations in htlv-i-infected blood donors. | the human t-cell lymphotropic virus type 1 (htlv-i) causes a neurological disease known as htlv-i-associated myelopathy/tropical spastic paraparesis (ham/tsp) in a minority of infected individuals. although other neurological outcomes have been described their prevalence is presently unknown. to evaluate the frequency and characteristics of neurological involvement in a population of htlv-i-infected blood donors we investigated 196 htlv-i positive and 196 negative blood donors from a blood cente ... | 2003 | 12972388 |
| htlv-i and htlv-ii infections in hematologic disorder patients, cancer patients, and healthy individuals from rio de janeiro, brazil. | to clarify the seroprevalence of human t-cell lymphotropic virus type i (htlv-i) among hematologic and cancer patients in the state of rio de janeiro, brazil, we investigated sera from 2430 individuals from the following groups: 152 patients with t-cell diseases, 250 with b-cell disorders, 67 with myeloid leukemia, 41 with hodgkin's disease, 351 with a history of multiple blood transfusions, 235 patients with solid tumors of different types, and 109 family members of htlv-i-infected patients. an ... | 1997 | 9257659 |

| inhibitory effect of extracts of brazilian marine algae on human t-cell lymphotropic virus type 1 (htlv-1)-induced syncytium formation in vitro. | extracts from four species of brazilian marine algae collected from the rio de janeiro state coast were screened to determine the inhibitory effect on htlv-1-induced syncytium formation. before performing the syncytium inhibition assay the 50% cytotoxic dose (cyd50) of the algal extracts was evaluated. the antiviral test was carried out in hela cells co-cultured with htlv-i infected t-cell line (c91/pl cells) in the presence of marine algal extracts in the concentration inferior to that correspo ... | 2002 | 11853002 |
| incidence of retroviruses in some brazilian groups. | the prevalence of human t lymphotropic virus type i (htlv-i) and human immunodeficiency virus (hiv) antibodies was evaluated in brazil among 116 aboriginal indians living in a pre-amazonian region, and in 44 patients with haematological malignant disorders being treated in rio de janeiro. screening for the presence of antibodies to hiv was performed routinely for 17,224 blood donors at the national cancer institute, rio de janeiro, from january 1986 to may 1987. the results demonstrated that hiv ... | 1988 | 2897948 |
