Sulfur mustard (2,2‐dichlorodiethyl sulfide; HD), is a potent alkylating agent which in liquid or vapor form is capable of causing severe injuries to skin and respiratory tract, and was shown to cause short‐ and long‐term ocular injuries. N‐Acetylcysteine (NAC) may act as a mucolytic agent, changing the “wetting” and scavenging properties of the cornea and thus the adhesion of HD. Moreover, NAC is a scavenger of HD, an antioxidant and a glutathione precursor, which was shown to reduce HD toxicity in various systems. The ocular distribution of 14C, after topical application of liquid 14C‐sulfur mustard (14C‐HD) to the rabbit cornea, and the role of NAC in reducing HD retention and toxicity are presented in this study. Groups of rabbits were exposed to 0.4 µL of liquid 14C‐HD, placed at the center of the cornea, with or without NAC treatment. Fifty µL NAC (10% aqueous solution) was topically applied, 10 minutes before and 10 minutes after HD exposure. Three time points were evaluated: 1, 6, and 24 hr after ...

Sulfur mustard(SM) has been used as a vesicant chemical warfare agent. To investigate the ocular damages it causes, we studied the effects on chemical casualties in the Iran-Iraq war. The patient material comprised over 5000 chemical casualties including both military and civilian populations. The results obtained show that the range of ocular damage was wide. The most common ocular effect were conjunctivitis and photophobia. Patients with significant corneal involvement are at risk for corneal ...

As part of a program to develop methods for diagnosis of exposure to chemical warfare agents, we developed immunochemical methods for detection of adducts of sulfur mustard to keratin in human skin. Three partial sequences of keratins containing glutamine or asparagine adducted with a 2-hydroxyethylthioethyl group at the ω-amide function were synthesized and used as antigens for raising antibodies. After immunization, monoclonal antibodies were obtained with affinity for keratin isolated from hu...

Ocular injuries following sulfur mustard (HD) exposure are characterized by an inflammatory response, observed as eyelid swelling, conjunctivitis, corneal oedema and cellular infiltration starting 1-4 h after exposure, depending on dose. These effects heal partially during the first 1-2 weeks after exposure, with the later appearance of neovascularization, recurrent erosions and recurrent oedema of the cornea (delayed response). We have shown previously that topically applied steroid treatment, ...

Sulfur mustard has been used as a vesicant chemical warfare agent. To investigate the ocular damage it causes, we studied the effects on chemical casualties in the Iran-Iraq War. The patient population consisted of more than 5,000 chemical casualties, both military and civilian. The range of ocular damage was wide. The most common ocular effects were conjunctivitis and photophobia. Patients with significant corneal involvement are at risk for corneal ulceration and rarely for anterior chamber sc...

Purpose. To establish an experimental model for sulfur mustard-induced acute and delayed ocular lesions in rabbits. Methods. Rabbit eyes were exposed to sulfur mustard (HD) vapor (370, 420 µg/l) for a period of two minutes. A three months follow-up study was carried out, based on the evaluation of clinical, biochemical and histological parameters. Results. HD exposure initiated typical clinical symptoms within 2–6 hrs, characterized by eye closure, eyelid swelling, conjunctival hyperemia, cornea...

The A549 cell line was used to assess the ability of diisopropylglutathione (DIPE) to protect against a 100 mM challenge dose of sulphur mustard (HD) using gentian violet (GV), thiazolyl blue (MTT) and neutral red (NR) assays as indicators of cell culture viability.As part of a continuing study of the efficacy of protective nucleophiles as candidate treatments for HD poisoning, several different combinations of protectant and HD were used to determine the optimal means of protecting A549 cells f...

The biochemistry and microstructure of the intermediate aqueous component of the tear film has been a subject of considerable interest over the past few years. Classical models of the tear film1,2 represent this layer as an aqueous fluid phase, 4–7 μm thick, bound to the hydrophobic corneal epithelium by a very thin layer of mucus.

In order to provide a quantitative basis for pretreatment and therapy of intoxications with sulfur mustard (SM) the toxicokinetics of this agent as well as its major DNA-adduct were studied in male hairless guinea pigs for the intravenous, respiratory and percutaneous routes. the study comprised measurement of the concentration-time course of SM in blood and measurement of the concentrations of intact SM and its adduct to guanine in various tissues at several time points after administration of,...

Abstract Sulfur mustard (SM) is a lipid soluble alkylating agent that causes genotoxic injury. The eye is highly sensitive to SM toxicity and exposures exceeding 400 mg min/m3 can cause irreversible corneal pathophysiologies. However, development of medical countermeasures for ocular SM exposure has been hindered by a limited understanding of dose-dependent effects of SM on corneal injury. Here, clinical, histological and ultrastructural analyses were used to characterize the effects of SM dose ...

Abstract In the long and intensive search for effective treatments to counteract the toxicity of the chemical warfare (CW) agent sulphur mustard (H; bis(2-chloroethyl) sulphide), the most auspicious and consistent results have been obtained with the drug N-acetylcysteine (NAC), particularly with respect to its therapeutic use against the effects of inhaled H. It is a synthetic cysteine derivative that has been used in a wide variety of clinical applications for decades and a wealth of informatio...

Abstract : The vesicating agent sulfur mustard (SM) continues to represent a worldwide threat because of the compound's ease of production, minimal cost of manufacturing, widespread stockpiling and the lack of definitive medical treatment. The vast majority of SM exposure cases involve corneal injury. At low-exposure doses, ocular irritation and inflammation will resolve within weeks and generally will not recur. However, higher exposure levels may result in a second phase of pathology that can ...
Corneal injuries resulting from ocular exposure to sulfur mustard (SM) vapor are the most prevalent chemical warfare injury. Ocular exposures exhibit three distinct, dose-dependent clinical trajectories: complete injury resolution, immediate transition to a chronic injury, or apparent recovery followed by the subsequent development of persistent ocular manifestations. These latter two trajectories include a constellation of corneal symptoms that are collectively known as mustard gas keratopathy ...

METHODS. Corneas of New Zealand white rabbits were exposed to SM vapor, and the corneal endothelium was evaluated at 1 day and 8 weeks using scanning electron microscopy (SEM), transmission electron microscopy (TEM), in vivo confocal microscopy (IVM), and fluorescent microscopy. Barrier function was measured by uptake of a fluorescent dye injected into the anterior chamber. RESULTS. A centripetal endothelial injury at 1 day was observed by SEM, TEM, IVM, and fluorescent microscopy. In vivo confo...

Objective: Ocular injuries following exposure to the toxic agent sulfur mustard (SM) are characterized by acute corneal erosions and inflammation of the anterior segment that may be followed by delayed corneal injuries, expressed clinically by neovascularization and epithelial defects. The present study aimed to investigate the effects of SM on corneal endothelium (CE) during the acute and delayed phase in relation to the development of the long-term pathology.Methods: Rabbit eyes were exposed t...

Publisher Summary This chapter describes the consequences of sulfur mustard (SM) exposure to the eyes and their treatments. Corneal SM exposure causes injuries that range from mild conjunctivitis to advanced corneal disease. As a warfare agent, SM is extremely effective because even mild ocular exposure causes some visual incapacitation and a panic and fear of blindness whose psychological impact cannot be underestimated. As for clinical symptoms, extensive military data have documented that the...
