In this article, we evaluated 17 Iranian soldiers who were exposed to mustard gas utilized by the Iraqi forces in the war fronts. Their clinical symptoms and signs, laboratory tests, and other parameters were carefully assessed, an attempt was made to identify a finding of prognostic significance, and patients who recovered from the acute phase were followed to determine possible long-term...

Following exposure to dilute aqueous solutions of mustard gas, suspensions of E. coli B do not produce DNA although PNA is formed in nearly normal amounts. When the treated cells are infected with virus T(2), DNA is synthesized and RNA is not. The DNA formation continued after the virus titer reached a maximum.

PURPOSE To evaluate the effectiveness of topical cyclosporine A 0.05% for treatment of mustard gas-induced ocular surface disorders with special attention to conjunctival goblet cell density in patients with severe dry eye. METHODS This prospective clinical study included 20 eyes of 20 patients previously exposed to mustard gas with dry eye syndrome unresponsive to artificial tears. Before an...

Perhaps it would be of interest to members of the Environmental Mutagen Society (EMS) to eavesdrop on my correspondence with H. J. Muller almost 50 years ago. I will, for the most part, let the letters speak for themselves, with a few brief comments and footnotes. Perhaps most remarkable is the pace of correspondence, which is a match for email today; perhaps the US Post Office was using its fa...

We studied the effects of hand weeding of second-year plants of the biennial garlic mustard (Alliaria petiolata) on first-year plants (seedlings) and native ground layer vegetation. Garlic mustard is a Eurasian species that has invaded deciduous forest ground layers in eastern North America. Treatments consisted of a control and an early or late weeding of second-year garlic mustard. The early ...

Background: During imposed war (1980-1988) Iraq frequently used chemical warfare particularly mustard gas. Skin is frequently involved in victims. Objective: Our main objective was to evaluate chronic skin manifestations due to exposure to mustard gas 10-19 years after exposure in a case-control study. Patients and Methods: 101 chemically wounded combators and 121 non-chemically wounded c...

PURPOSE To report the long-term outcomes of penetrating keratoplasty (PKP) in war victims with chronic and delayed mustard gas keratitis. METHODS This noncomparative interventional case series includes patients with advanced chronic or delayed mustard gas keratitis who had undergone PKP from 1989 to 2006. Best-corrected visual acuity (BCVA), graft clarity, episodes of graft rejection, duratio...

The use of mutagenis to produce strains with desired characteristics including increased biosynthetic capacity is an established part of industrial research (Stauffer and Backus, 1954; Dulaney, 1955; Backus and Stauffer, 1955). Publications indicate that much of this work has been done with ionizing and nonionizing radiation. The mutagenic effect of mustard gas for Drosophila spp. (Auerbach et ...
