Abstract

A sudden discharge of Sidoarjo mud flow into the water bodies would disturb aquatic biota, the fisheries culture. The aim of this research is to evaluate the availability of phytoremediated water of Sidoarjo mud flow (abbreviated: pwmf) as a milkfish culture media using liver histological approach. After two weeks acclimatization period, the juvenile and adult of milkfish were exposed the pwmf at the sub lethal concentration and an acute static bioassay at 96 hours. Control fishes were reared in the artificial brackish water. Each treatment of pwmf exposure was done in three replicates. After exposure, the liver fishes were removed and histologically processed using paraffin method and HE staining. Histopathology change was assessed semi quantitative scoring. The result of the histological analyses suggested the liver pathological features such as vacuolation of hepatocytes, the loss of sinusoid integrity from mild to severe occurrence and necrosis.

Abstract

The sponge Aaptos suberitoides can produce high secondary metabolite with some farmocological activities as antimicrobial, antiviral, antiinflamatory, and anticancer agents. The purpose of this research is to find out correlations between activities of the etanol extracts of marine sponges Aaptos suberitoides on the cancer growth of subcutaneous mice (Mus musculus) injected by Benzo(a)piren. For the purpose the mice were divided into six groups, i.e. I, II, III, IV, V, and VI. Each group was treated with carcinogenic inductions by intravenously injecting the Benzo(a)piren concentration of 0.3g/0.2 ml oleum olivarum. After the cancer was appeared at the fifteenth day, the mice were treated by the anticancer extracts of marine sponges Aaptos suberitoides with concentrations of 500 mg/kg BB (Group IV), 1000 mg/kg BB (Group IV), and 1500 mg/kg BB (Group IV). The treatments were orally done each day for two weeks. At the twentieth week, subcutaneous cancer tissues were taken to make histological preparates using a parafin method. Result of the histological observation indicates that cancer in the mice was fibrosarcoma characterized by the thickening dermis layers, necrosis, mitosis, and nuclear polymorphsm. Necrosis, mitosis, and nuclear polymorphism occurred in Groups II, IV, V, and VI, and did not in Groups I and II. Presentation of necrosis was 20-60%, mitosis was in 3-4 cells, and nuclear polymorphism was 100%. Result of the statistical analyses by using the Kruskal-Wallis method and the Pair Comparison test indicates that the anticancer extracts of marine sponges with the concentrations of 500 mg/kg BB, 1000 mg/kg BB, and 1500 mg/kg BB had no activity inducing mice skin cancer.
