Absorption Coefficients

A method for retrieving the absorption coefficients of Spirulina platensis pigments using absorption spectra of native cells and excluding the use of extracts is considered. Estimates of the intracellular concentration of chlorophyll a, С-phycoerythrin, С- phycocyanin and allophycocyanin in native cells are discussed.

Toksoplasmosis adalah penyakit yang disebabkan oleh infeksi Toxoplasma gondii. Penyakit ini sangat berbahaya pada hewan maupun manusia. Toksoplasmosis sampai sekarang masih sulit ditanggulangi. Untuk itu, dicari akternatif dengan cara pemberian imunostimulator, seperti Spirulina platensis. Tujuan penelitian ini adalah untuk mengetahui ekstrak Spirulina platensis yang paling potensial meningkatkan respon imun humoral dan mengetahui dosis Spirulina platensis yang efektif dalam meningkatkan respons imun humoral. Rancangan penelitian adalah Rancangan Acak Lengkap pola Faktorial. Faktor pertama adalah jenis ekstrak (ekstrak etil asetat, ekstrak air dan Spirulina platensis murni). Faktor kedua adalah dosis ekstrak (0, 5, 10, 15 mg/ekor mencit). Hasil penelitian menunjukkan bahwa ekstrak etil asetat dengan dosis 5 mg/ekor mencit adalah yang terbaik meningkatkan respon imun humoral. Uji lanjut dengan Latin Square Design (LSD) menunjukkan bahwa terdapat interaksi antara jenis ekstrak dan dosis ekstrak.

Wound Healing Activity

Spirulina is a microalga used in traditional folk medicine in Morocco for the treatment of various health disorders. The wound healing activity of Moroccan Spirulina is unknown. In the current study, aqueous extracts of Spirulina platensis were investigated for acute toxicity and wound healing activity in Swiss Albino mice and White New Zealand rabbits, respectively. The LD50 (amount of substance required to kill 50% of the test population) of the microalga was greater than 5,000 mg/kg. Healing after application of the same amount of ointment on differently induced (mechanical, chemical, and thermal) wounds was about the same, over five weeks. Aqueous extract had remarkable healing activity on rabbits’ skin, possessing significantly greater healing effect for mechanical and chemical burns than controls. Moreover, the hair growing time was faster in treated groups; Spirulina-treated groups did not show any contamination with microbes compared to others. This study affirms that Spirulina platensis can be considered as a potential therapeutic agent for wound healing not only as a complementary medicine but also in conventional medicine.
