For the purpose of determining the effect of levamisole on cell-mediated immunity of patients with herpetic stromal keratitis, the response of peripheral lymphocytes to three mitogens (PHA, Con A and PWM) was examined in a total of 19 cases of herpetic stromal keratitis (16 effective cases) including 12 patients undergoing levamisole administration. As controls, a similar study was made on 35 h...

A strain of Haemonchus contortus from the Pietermaritzburg district of Natal was found to be resistant to levamisole (geometric mean efficacy 76.5%), morantel (41.9%), the benzimidazoles (oxfendazole: 33.7%) and rafoxanide (82.0%), but apparently fully susceptible to closantel and disophenol. In the case of ivermectin, a mean of 5.2% of the H. contortus was not removed at a dosage of 200 microg...

Metho ds : Piglets (N = 1606) from a commercial segregated early-weaned (SEW) herd were randomly assigned either to receive one injection of levamisole within 24 hours of birth (T1 group), to receive levamisole once within 24 hours of birth and again at weaning (T2 group), or to a control group. Pigs were individually weighed within 24 hours of birth, at weaning, and at 7 weeks of age. Differen...

Levamisole, which is an anthelminthic, can restore depressed cell-mediated immunity (CMI) under some circumstances. In a controlled trial of experimental herpetic keratis in rabbits, levamisole was found to have no significant effect on acute herpetic keratitis or its recurrence rate. This is consistent with previous findings that other nonspecific CMI stimulation had no effect on recurrences o...

The anthelmintic drug levamisole causes hypercontraction of body wall muscles and lethality in nematode worms. In the nematode Caenorhabditis elegans, a genetic screen for levamisole resistance has identified 12 genes, three of which (unc-38, unc-29, and lev-1) encode nicotinic acetylcholine receptor (nAChR) subunits. Here we describe the molecular and functional characterization of another lev...

Levamisole is an antibiotic medication used to treat colon cancer and is a synthetic imidazothiazole derivative also employed as an antihelminthic to treat worm infestations in both humans and animals. Even if it is not yet well known why levamisole is added to cocaine, the presence of this adulterant is very dangerous, in fact this compound suppresses the production of white blood cells, resul...

BACKGROUND Hemodialysis patient are at high risk for hepatitis B virus (HBV) infection. Although preventive vaccination is done routinely, the response to vaccination is low in this patient population. The aim of this study was to evaluate the effect of Levamizol, an enhancer of the immune responsiveness, on different routes of vaccination, i.e., intradermal (i.d.) versus intramuscular (i.m.), ...

Ninety-nine gastric cancer patients initially received levamisole at a daily dose of 150 mg for three consecutive days before operation. This therapy was repeated fortnightly (3-day administration followed by 11-day withdrawal period) for more than one month as long as possible and the survival rate up to 18 months was compared with thas of control patients. The 18 month survival rate of advanc...

Cell-mediated immunity was studied in 23 cases of advanced gastrointestinal cancer. The patients received levamisole at 150 mg/day for three consecutive days each week for four weeks. In cases at the terminal stage of gastrointestinal cancer, the blastformation rate of peripheral blood lymphocytes against phytohemagglutinin (PHA) after the administration of levamisole showed a slight increase, ...

Cocaine is used by approximately 1.5 million Americans each month and up to 69% of the cocaine seized contains levamisole. The real incidence of cocaine-levamisole induced neutropenia is unclear but probably underestimated. Associated complications include fever, thrombocytopenia, skin-vasculitis disorders, and rarely kidney injury. We present a young male, with chronic active cocaine use prese...
