Levamisole has been increasingly used as an adulterant of cocaine in recent years, emerging as a public health challenge worldwide. Levamisole-associated toxicity manifests clinically as a systemic vasculitis, consisting of cutaneous, hematological, and renal lesions, among others. Purpura retiform, cutaneous necrosis, intravascular thrombosis, neutropenia, and less commonly crescentic nephriti...

Nicotinic acetylcholine receptors (nAChRs) are pentameric neurotransmitter-gated ion channels that mediate synaptic transmission throughout the nervous system in vertebrates and invertebrates. Caenorhabditis elegans is a nonmammalian model for the study of the nervous system and a model of parasitic nematodes. Nematode muscle nAChRs are of considerable interest because they are targets for anth...

Ascariasis is very common in indigenous chicken causing retarded growth, low productivity and mortality. Considering the problem of Ascaridia galli in chicken, anthelmintic resistance, high cost and human health hazard of chemical anthelmintic the use of medicinal plant is an alternative choice. An experiment was conducted in the Department of Pharmacology, Bangladesh Agricultural University, M...

BACKGROUND Levamisole is a common adulterant of cocaine. It can cause agranulocytosis and cutaneous vasculitis that can possibly lead to cutaneous necrosis. In all reported cases of levamisole-induced vasculitis, it has been described as a clinical syndrome characterized by a constellation of typical clinical features and a positive serum serology for ANCA levels, especially very high-titer p-A...

Levamisole has previously been identified as an inhibitor of angiogenesis in vitro and in vivo, but the mechanism behind the anti-angiogenic behavior has not yet been established. However, one known effect of levamisole is the inhibition of alkaline phosphatase, and this fact encouraged us to test other phosphatase inhibitors for their anti-angiogenic effects by using the same method as used to...

Background & Aim: One of the major problems of modern medicine is the increasing consumption of synthetic drugs and frequent use of them will result in side effects. Considering this issue, patients should be mainly motivated to use pharmaceutical plants. Regarding the positive effects of sumac on the immune system, in the present study, we made a decision to compare sumac with...

Zataria multiflora essential oil possesses immunomodulatory effects and the present study investigatesits effect on immune responses to live Newcastle disease (ND) vaccines and faecal shedding period ofvaccine strain virus in chickens. One hundred and eighty chickens from both sexes were divided into 6 equalgroups: group 1: unvaccinated, group 2: vaccinated (B1 vaccine followed by La Sota 10 da...

Objective. To study the effect of immunomodulators on learning and memory and on cholinergic receptor sensitivity. Methods. Animals were initially treated for a period of 8 days with cyclosporine/levamisole/saline. They were then subjected to passive avoidance training and 48 hrs later, the retention test for the passive avoidance task was conducted. Twenty-four hours after the retention tests ...
