    Long before its popularization as a skincare ingredient, snail slime was reported to have a variety of health-promoting attributes. Its medicinal use involved the treatment of ailments, such as anthrax, hernias, stomach pain, chest pain, as well as tuberculosis. The main aim of this study was to investigate the anti-inflammatory and wound-healing properties of snail slime from Cepaea hortensis (Müller, 1774) (brown garden snail). The slime was extracted by a mild method, and the anti-inflammatory characteristics were determined by croton-oil-induced mouse-ear edema. The histological study showed that the snail slime exerts its action at the level of inflammatory mediators, explaining the drastic decrease of edema (59% in comparison to the 47% of indomethacin). The daily application of 50 µL (15 mg/kg) of snail slime on excision wounds in rabbits proved to induce an almost full tissue repair after 24 days of treatment (87.80–92.7% wound closure in width and length, respectively). Analysis of the slime’s safety aspect allowed affirming the nontoxicity of snail slime on both the skin and eyes.info:eu-repo/semantics/publishedVersio

    Histamine poisoning is a significant public health problem. Therefore, the monitoring of histamine content in fish and fishery products is considered to be a crucial measure in the seafood industry. In the present study, a simple and rapid densitometric thin-layer chromatographic (TLC) method for histamine determination in fish samples was developed and validated. The samples were homogenized with 10% trichloroacetic acid and histamine was efficiently extracted. Then, an appropriate derivatization procedure was adopted with dansyl chloride. Once the derivatization was carried out, the samples were applied to silica gel TLC plates and developed by ascending chromatography with chloroform-triethylamine (6:4, v/v) as the mobile phase. The intensity of the histamine-dansyl derivative spots was measured by densitometry at 365 nm, and the quantitation was performed by BIO-1D image processing software. The validation of this method revealed good linearity and specificity over a concentration range from 6.25 to 100 mg/kg. Adequate precision was shown by relative standard deviations (RSD) smaller than 4.82%, accuracy ranged from −6.88% to 5.28%, and satisfactory recoveries ranging from 93% to 105% were obtained. The Limit of Detection and the Limit of Quantification were calculated at 4.4 mg/kg and 10.5 mg/kg, respectively. In addition, the effectiveness of the proposed method was assessed by the analysis of various samples, and the obtained results were confirmed with those achieved by the HPLC-UV method. Moreover, the developed method was found to be simple, cheap, and suitable for application to analyze several samples simultaneously
