background cutaneous leishmaniasis is a health problem in the world. lesions should be treated on cosmetically or functionally important sites, such as the face and hands. cantharidin is a terpenoid compound produced naturally by beetles of meloidae and oedemeridae families. objectives the current study aimed to investigate the effect of cantharidin on cutaneous leishmaniasis (cl) lesions and i...

Twelve cloned viruses were randomly isolated from original (uncloned) vesicular stomatitis virus (VSV), and their sensitivities to mouse and human interferons were examined. When the interferon sensitivities of these various VSVs were compared by the plaque reduction method in L cells, virus 3 was found to be sevenfold more sensitive than virus 11, and the interferon sensitivity of the original...

BACKGROUND After treatment cessation, a high prevalence of relapse was reported in chronic hepatitis B (CHB) patients in China, especially in nucleot(s)ide analogues (NUCs)-experienced patients. Re-treatment for these patients remains unsolved. OBJECTIVES This study aims to evaluate the efficacy of PEGylated interferon in HBeAg positive patients with exposure to antiviral therapy. PATIENTS ...

The benefit of the triple therapy (interferon + amantadine + ribavirim) is still unknown. The efficacy of induction doses of interferon-alpha-2a monotherapy or in combination with ribavirin and/or amantadine was evaluated in interferon non-responders with chronic hepatitis C. A total of 378 patients were randomized. All the groups received the same doses and duration of interferon-alpha-2a: (i)...

The innate host response to virus infection is largely dominated by the production of type I interferon and interferon stimulated genes. In particular, fibroblasts respond robustly to viral infection and to recognition of viral signatures such as dsRNA with the rapid production of type I interferon; subsequently, fibroblasts are a key cell type in antiviral protection. We recently found, howeve...

Gauntt, Charles J. (The University of Texas, Austin), and Royce Z. Lockart, Jr. Inhibition of Mengo virus by interferon. J. Bacteriol. 91:176-182. 1966.-The inhibition of Mengo virus replication in L cells resulting from interferon was studied quantitatively. Interferon was titrated on L cells with Western equine encephalomyelitis (WEE) virus as the challenge virus. One protective unit (PU) of ...

BACKGROUND Hepatitis C virus infection is a global health problem. New direct-acting antiviral agents have been recently approved. However, due to their high cost and some genotypes remaining difficult to treat, interferon-based therapy with pegylated interferon and ribavirin likely may remain a component of hepatitis C virus treatment for some patients. Unfortunately, pegylated interferon / ri...

A viral inhibitor with the characteristics of mouse interferon is produced by avian and simian cells preincubated with RNA extracted from interferon-producing mouse cells. Similarly, RNA extracted from interferon-producing monkey cells induces a monkey interferon-like substance in avian cells and also in a line of simian cells, VERO, which normally lacks the capacity to produce its own interfer...

Structural differences between human leukocyte virus-induced interferon and human fibroblast polyinosinic-polycytidylic acid (rIn-rCn)-induced interferon have been noted in previous studies. This study reports the behavior of human leukocyte and fibroblast interferon, induced by virus and by rIn-rCn, in several lectin and hydrophobic chromatographic systems. Differences in both glycosylation an...

Treatment of Daudi cells with successively increasing concentrations of interferon-alpha resulted in the selection of a cell population which multiplied in the continued presence of 10(4) units/ml of interferon-alpha. A number of clones of interferon-resistant Daudi cells were isolated from this population. Two clones, DIF2 and DIF3, were found to exhibit moderate and pronounced resistance, res...
