cerato-ulmin is the most important toxin of fungal causal agents of dutch elm disease and its content is one of the most important factors to distinguish two species ophiostoma ulmi and o. novo-ulmi. with attention to the ophiostoma novo-ulmi is more pathogenicity than o. ulmi, this research was carried out to discuss the role of cerato-ulmin on pathogenicity of causal agent using measurement o...
background: we aimed to study the curative effects of botulinum a toxin (btx-a) on the treatment of post-herpetic neuralgia (pnh). methods: we enrolled 58 pnh patients and treated them with hypodermic injection of btx-a in xiangyang no.1 people’s hospital, hubei university of medicine, hubei, china. we measured and compared the visual analog score (vas), neuropathy pain scale (nps), quality of ...
introduction: scorpion venoms contain a variety of peptides, toxic to mammals، insects and crustaceans and are the main factors in scorpion venom toxicity (their amount being 1-3% of total venom). most of the scorpion toxins have been isolated from the venoms of scorpions in the buthidae family. the scorpion buthotus schach of this family is widely found in the western regions of iran, but no p...
our aim was to evaluate the short and long term efficacy of botulinum toxin therapy in iranian patients with achalasia. in a randomized, double blind trial, 20 patients with achalasia, referring to imam khomeini hospital, received either 80 units of botulinum toxin (bt) or placebo (pl) from 1995 to 1998. two weeks later, the response to treatment was assessed on the basis of changes in the symp...
to study the existence of clostridium septicum as probable agent associated with currently occurrence of black quarter in urmia area, sheep-dung samples were collected. the bacteriological examinations on suspicious gram positive anaerobic spore-bearing bacilli which are in clostridia genus include isolation and biochemical identification were performed. the results showed 28 different types of...
a purification procedure of pertussis toxin (pt) from submerged culture of bordetella pertussis (b.pertussis) strain 134 using adsorption and affinity chromatography was discussed. the yield of the resulting pt was approximately 37.5mg/l of concentrated culture supernatant. the polypeptide pattern of the purified pt was investigated by sds-page and showed five bands between 11 to 26 kda using l...
this study was carried out to examine aflatoxin b1 (afb1) removal ability of four strains of lactic acidbacteria (lab). three indigenous (lactobacillus rhamnosus tmu094, lactobacillus fermentum tmu121and pedioccus pentosaceus tmu457) and a non-indigenous (labacillus rhamnosus ptcc1637) isolateswere studied. the strains were incubated with (afb1) at different time. the toxin residual in the supe...
Although the widespread distribution of venomous marine worms around the world, the structural and toxinologcal studies of their toxins are still limited.This study was aimed to evaluate the toxicity of poisonous marine worms. Touching the cilium of Chloeia flava and Sipuncula marine worms cause painful inflammation of the skin. Many species of nemertines prey their victims by a flexible prob...
Botulinum toxin (BoNT), being one of the most toxic substances known to mankind, due its unique mechanism action is used as an effective treatment for many diseases, including strabismus, blepharospasm, and hemifacial spasm. BoNT has received particular use a long-acting analgesic ability inhibit exocytosis pain neuropeptides, CGRP, Substance P, modulate expression pain-related receptors TRPV1,...
Rhizoctonia solani causes stem canker and significantly impacts potato production. Conventional assay to evaluate resistance using R. inoculum is time consuming. To establish an effective fast assay, 20 cultivars/lines were examined both AG2-1 as its derived toxin (RS toxin). In field trials of 2009 2010, wheat-bran-mediated was incorporated at either 0, 2, 3, 4 or 5 g per seed piece in the soi...
