Endometriosis is a chronic estrogen-dependent inflammatory disease of unclear etiology that affects 15-20% of women of reproductive age. Efforts are now focusing on understanding new mechanisms involved in its physiopathology, like novel target pathways and different molecules. There is evidence that mast cells (MCs) play a role in this disease. This article summarizes recent achievements in preclinical studies and clinical activities investigating the role of MCs in endometriosis. Targeting MCs might offer new alternatives to treat this disease. Areas covered: A systematic literature search was performed (PubMed, Cochrane Library and ClinicalTrials.gov) using the keywords 'endometriosis and mast cells'. All relevant articles (34) found in PubMed were examined and their reference lists reviewed in order to pinpoint further studies for potential inclusion. Expert opinion: Since endometriosis is a multifactorial disease, and considering that numbers of MCs and activated MCs were clearly increased in endometriotic lesions in both animals and humans, use of MC stabilizers and inhibitors may prove to be effective to treat endometriosis and its associated pain. However, more data from preclinical studies and clinical trials will help to better define the status of MCs in the treatment of this pathology.

Two chromatographic methods were developed and validated for the simultaneous determination of Sodium Cromoglycate (SCG) and Oxymetazoline Hydrochloride (OXMT). SCG and OXMT are administered in combination for effective treatment of nasal congestion and allergy. The first chromatographic method was based on usingaluminum TLC plates pre-coated with silica gel GF254 as the stationary phase and chloroform: methanol: toluene: triethylamine (5: 2: 4:1, by volume) as the mobile phase followed by densitometric measurement of the separated bands at 235 nm. The second method is a high performance liquid chromatographic method for separation and determination of SCG and OXMT using reversed phase C18 column with isocratic elution. The mobile phase composed of acetonitrile: methanol (2: 1, v/v) at flow rate of 1.0 mL/ min. Quantitation was achieved with UV detection at 220 nm. The validity of the proposed methods was assessed using the standard addition technique. The obtained results were statistically compared with those obtained by the official methods, showing no significant difference with respect to accuracy and precision at p = 0.05.
