Cattle were infected with three isolates of Theileria parva and treated with halofuginone lactate during acute clinical disease. The health, weight gain and carrier state of the cattle were monitored for 15 months. Limited treatment rapidly reduced fever and parasitosis but parasite recrudescences occurred and 12 out of 21 treated cattle died. Persistent carrier states were identified with two ...

The in vitro release of vancomycin, teicoplanin, gentamicin and clindamycin from biodegradable calcium sulphate (CaSO(4)) carrier beads is described. All antibiotics showed prolonged release from the carrier beads, which was elevated during the first 24 h, with peak levels exceeding 2500 microg/bead. Doubling the antibiotic load of the beads revealed a more prolonged elution and a two-fold incr...

parasitic colitis, especially entamoeba histolytica, is a well-known disorder in the middle east particularly in iran. the carrier state of the disease or the chronic type frequently remains undiagnosed or mistaken as irritable bowel syndrome which results in further discomfort and increases the incidence of associated complain. we devised a technique by inserting bisacodyl suppository and then...

background and objectives: beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. thus, the objectives are to study the validity of naked-eye-single-tube-osmotic-fragility-test (nes...

BACKGROUND Prior to the introduction of universal hepatitis B virus (HBV) vaccination in Taiwan in 1984, 15-20% of the general population were chronic HBV carriers. METHODS We forecasted and quantified the declining HBV carrier rate 20 years subsequent to the implementation of universal HBV vaccination in Taiwan. At a Taiwanese university, 28,763 freshmen tested for serum HBsAg level were div...

This study investigated thirty patients with chronic hepatitis B who were admitted to Hepatology and Gastroenterology Teaching Hospital in Baghdad, aged from 20-65 years during the period from beginning of February 2008 to the end of February 2009. The patients were suffering from different clinical symptoms with previous risk factors for transmission of HBV infection, also blood samples were c...

C3H mice chronically infected with LCM virus were found to be lethally affected by small doses of immunosuppression which caused bone marrow aplasia but had no effect on the amount of virus carried by the mouse. Humoral immune response of SWR/J mice to acute LCM infection was found to be totally suppressed by repeated single doses of 300 R/wk with no alteration in the level of virus carried by ...

Persistence of even the stealthiest viruses can perturb immune function either to the benefit or detriment of the host. Lymphocytic choriomeningitis virus (LCMV) establishes lifelong, systemic persistence when introduced in utero or at birth. Despite a highly evolved host-pathogen relationship, LCMV cannot escape detection by the innate immune system, which results in chronic stimulation of the...

BACKGROUND Angiotensin-converting enzyme (ACE) plays an important role in vascular remodeling in pulmonary hypertension, and ACE gene polymorphism is associated with exercise-induced pulmonary hypertension in Japanese patients with chronic obstructive pulmonary disease. The present study was designed to investigate if ACE-insertion (I)/deletion (D) polymorphism might be related to the susceptib...

The use of carrier cells infected with oncolytic viruses in cancer gene therapy is an attractive method because it can overcome viral immunogenicity and induce tumor immunity and significant antitumor activity. To enable human clinical trials of this treatment, acute and chronic toxicity tests must first be performed to ensure safety. IAI.3B promoter, oncolytic adenovirus AdE3-IAI.3B introduced...
