As a harmful and non-degradable heavy metal, lead (Pb) is also toxic to aquatic organisms. This metal damages tissue and sensitive organs such as gills. A study dealt with the effect of Pb concentration and contact time on gill microanatomy structure of hard-lipped barb fish (Osteochilus hasselti). An experimental method was applied during study with Completely Randomized Design to test 4 concentrations of Pb, i.e 0 mg/L (P0), 8.93 mg/L (P1), 17.86 mg/L (P2) and 26.80 mg/L (P3), in quadruplicates. The gills were removed, and fixed in Bouin solution, from fish sampled twice in a month. The gills were subsequently processed in classical histology to obtain gill microanatomy structure damage data. The data were established from Pantung method, which were then analyzed with One-way ANOVA. The results showed that Pb damaged gills, mildly to severely, in form of oedema, hyperplatia, lamella fusions, and necrosis. Concentration levels and contact time affected microanatomy structure damage of gills. The increasing concentration levels and length of contact time did not gravely increase in damage.

There is a growing need for new antibacterial agents, in particular because many antibiotics are becoming ineffective due to the emergence of resistant bacterial strains. Soft corals of the Genus Sinularia, Family Alcyoniidae, have potential as a source of terpenoid and steroid compounds with antibacterial activity. These corals may vary in external morphology (shape, colour, size).The aim of this research was to identify extracted fractions with high antibacterial activity. Sinularia sp. specimens were extracted, fractionated based on solvent polarity, and tested for antibacterial bioactivity against pathogenic bacteria (Escherichia coli and Staphylococcus aureus). Antibacterial activity of the three fractions varied in strength. The dichloromethane fraction showed strong antibacterial activity, inhibiting S. aureus and E. coli growth at a concentration of 1 mg ml-1, while the ethyl acetate and ethanol fractions were effective at 10 mg ml-1 and 100 mg ml-1, respectively.
