ATROPINE, perhaps the drug most used in ophthalmology, is prone to cause contact-irritation, often at a time when continued mydriasis is essential, in patients on long-term treatment. Unfortunately, most substitutes are less effective in producing mydriasis, and not infrequently contact-irritation is developed to these substitutes in rapid succession. Lachescine (E3) was developed in Great Brit...
OBJECTIVE To evaluate the safety of the antimicrobial peptide, lactocin 160. METHODS Lactocin 160, a product of vaginal probiotic Lactobacillus rhamnosus 160 was evaluated for toxicity and irritation. An in vitro human organotypic vaginal-ectocervical tissue model (EpiVaginal) was employed for the safety testing by determining the exposure time to reduce tissue viability to 50% (ET-50). Hemol...
Sodium and Ammonium Lauryl Sulfate are anionic surfactants used in cosmetics as cleansing agents. In absorption, metabolism, and excretion studies, Sodium Lauryl Sulfate had a degenerative effect on the cell membranes because of its protein denaturing properties. Low levels of skin penetration may occur at high use concentration. Sodium Lauryl Sulfate had an LD50 of 0.8 to 1.10 g/kg in rats. A ...
Sir, Mechanical irritation interdental loop wiring and intermaxillary fixation causes inflammation of oral mucosa, marginal gingiva and lips is virtually unavoidable in maxillofacial surgery.[1] Filippi et al. compared different types of splints (composite wire splinting, button bracket splinting, resine splinting and titanium trauma splinting) by means of irritation on gingival mucosa and lips...
Irritation of eyes and upper airways--sensory irritation--is commonly used as a parameter for setting occupational exposure limits and is a common complaint in occupants of non-industrial buildings. Sensory irritation occurs from stimulation of receptors on trigeminal nerves. In general, chemically reactive compounds are more potent than non-reactive congeners. Animal studies allow prediction o...

It is known that perceived intrusiveness and privacy concerns, mediated by irritation, indirectly affect advertising avoidance. This research attempts to verify the importance of value investigating its moderated mediation effect on links between those endogenous variables. The model was empirically verified with data derived from 374 valid off-line responses. Analysis found both concerns incre...
