В связи с нововведениями обостряются существующие проблемы безопасности водного транспорта. Обращается внимание на тот факт, что существующая система безопасности водного транспорта не учитывает географический, технологический и отраслевой факторы. Реализация концепции транспортной безопасности на водном транспорте взывает немало вопросов, определяющих существование отрасли. In connection with the innovations, the existing problems of the safety of water transport are aggravated. Attention is drawn to the fact that the existing water transport safety system does not take into account geographical, technological and sectoral factors. The implementation of the concept of transport security in water transport raises many questions that determine the existence of the industry.

Allergic Effect

Background: Sargassum polycystum C. Agardh has potent antioxidant and anti-inflammatory properties. However, its anti-allergic effect has not yet been reported. In this study, we investigated the anti-allergic effects of sulfated polysaccharide of S. polycystum (SPSP) in Dinitrofluorobenzene (DNFB)- induced allergic contact dermatitis animal model. Methods: SPSP was extracted through hot water extraction method and was subjected to compositional analyses. For the allergic contact dermatitis (ACD) model, symptoms were induced by the topical application of 0.5% DNFB on the shaved ventral skin of mice. SPSP (500, 1000, and 2000 mg/kg) and Prednisolone were orally administered for seven days after sensitization. Elicitation was performed seven days later with 0.2% DNFB. After this, ear thickness was measured at baseline and 24 hours post elicitation using a dial thickness gauge. Serum of mice was obtained 24 hours post elicitation, and the level of IFNγ and TNF Results: SPSP afforded 33.6% carbohydrates, 23.7% sulfate, 7.5% protein, and 1.5% uronic acid contents. SPSP inhibited the ear swelling and cytokines (IFNγ and TNF Conclusion: These findings showed that the sulfated polysaccharide from S. polycytum is a potential natural source to treat Allergic Contact Dermatitis. The effect is attributed to polysaccharide-protein complex present in the extract, but further studies are needed to establish the exact mechanism of action of SPSP in the treatment of the disease.
