However, the acute nature of such CDK inhibitor an inhibitory effect remains controversial. In this study, we investigated the acute effects of SS

IgG on muscarinic receptor function in human submandibular gland (HSG) cells. METHODS: The effects of autoantibodies on muscarinic receptor function were studied using microspectrofluorimetry, whole-cell patch clamp, immunofluorescence confocal microscopy, and a co-immunoprecipitation assay. RESULTS: Carbachol (CCh) was found to consistently increase intracellular calcium concentration ([Ca(2+)](i)) and activate K(+) current in HSG cells. However, pretreatment of the cells with SS IgG for 5 or 30 min significantly attenuated these responses, with a substantially more prominent effect after 30 min of treatment. Like CCh, adenosine 5′-triphosphate

(ATP) also increased [Ca(2+)](i) and activated K(+) currents in HSG cells, although pretreatment with SS IgG did not affect the cellular response to ATP. CCh was found to reorganize a-fodrin in HSG cells in a Ca(2+)-dependent manner. However, pretreatment with SS IgG prevented the cytoskeletal reorganization of a-fodrin induced by CCh. CONCLUSIONS: SS IgG acutely and reversibly inhibited muscarinic receptor function, thereby inhibiting the Ca(2+) mobilization necessary for the activation of K(+) currents and alpha-fodrin reorganization in HSG cells.

“Introduction: Hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC)-Lyral (R) is a widely

used synthetic fragrance found RepSox molecular weight in personal care and household products. It is an aldehyde, lipophilic enough to penetrate the skin and is a frequent click here cause of contact sensitization.

Objective: Describe the frequency of contact allergy to HICC in a Contact Dermatitis Unit, after its inclusion in baseline patch test series.

Methods: A retrospective study including all patients submitted to patch test, from January 2007 to December 2009.

Results: Over a 3-year period, 629 consecutive patients were patch tested. The frequency of positive reactions to HICC was 2.7% (17/629). Of the positive patients, 35% (6/17) gave a history of atopy, 58.8% (10/17) had eczema on the face and neck, 23.5% (4/17) on the hands, 23.5% (4/17) in the axillae, 17.6% (3/17) on the trunk and 6% (3/17) had generalized eczema. All patients were patch positive for more than one allergen: all (17/17) positive to fragrance Mix 2 (FM2); 47% of the patients (8/17) positive to fragrance Mix 1 (FM1); and 23.5% of the patients (4/17) positive to Balsam of Peru. In 94% (16/17) of cases, the reaction was judged to be of current relevance.

Discussion: The frequency of positive reactions to HICC of 2.7% found in our population is according to what is described in several European reports, where HICC is still widely used as a fragrance ingredient. In contrast, in North America, the prevalence is lower.
