Toxoplasma gondii is an obligate intracellular protozoon, spread world-wide and capable of infecting birds and mammals. Genetic information on T. gondii type that causes human toxoplasmosis is limited. In this study, genetic analysis of SAG2 locus was used to determine the genotype of T. gondii from cases with cerebral and ocular toxoplasmosis in Indonesia. Genotype determination was done directly on the clinical samples. A number of 28 cerebrospinal fluid and 8 vitreous humor positively infected with T. gondii, underwent PCR-RFLP to classify each isolate into one of three genotypes of T. gondii. Type I was the most common found suggesting that cerebral and ocular toxoplasmosis in Indonesia is mostly caused by type I strain of T. gondii.

Refractory and mortality associated with status epilepticus (SE) were correlated with the degree of inflammation-induced neuronal cell death. This study was aimed to investigate the correlation of oxidative stress (Malondialdehyde, MDA) and inflammation (C-reactive protein, CRP) process with neurodevelopmental outcome in children after the episode of convulsive type SE. This study was designed as cross sectional which included 26 convulsive type SE subjects and 15 control subjects. MDA level was measured by thiobarbituric acid (TBA) method, while CRP level was measured by ELISA method. Neurodevelopmental outcome was measured by Bayley-III Scale of Infant and Toddler Development 3 month after the convulsive type SE episode. Results showed that both MDA (independent t-test, p < 0.05) and CRP (Mann-Whitney test, p < 0.05) level was significantly higher in convulsive type SE group as compared to control group. Further analysis also showed that MDA (Spearman correlation test, p = 0.000, r = 0.756) and CRP (Spearman correlation test, p = 0.000, r = 0.835) level was positively correlated with convulsive type SE. In convulsive type SE group, MDA level was negatively correlated with neurodevelopmental outcome but CRP was not. We concluded that MDA level was negatively correlated with neurodevelopmental outcome in children with convulsive type SE, but CRP was not.

Parasitic isopods are causing problems to the worldwide fishery resources. The studies on parasitic isopods are very scanty in Andaman Islands. So here we provided information on the distribution of two species of parasitic isopods of fishes from Junghlighat fish landing center of South Andaman. The two marine parasitic isopods species are Argathona rhinoceros (Bleeker 1857) and Argathon amacronema (Bleeker 1857). They found to infest the host marine fishes Epinephelus coioides (Hamilton 1822) and Epinephelus tauvina (Forsskal 1775) respectively. These two species were collected from the nostril cavity of the individual host fishes. The morphological characteristics of two specimens are described in detail. Prevalence of corallinids provides additional information to update the check list of isopods from Andaman and Nicobar Islands.

Lupus nephritis (LN) is one of the manifestations of Systemic Lupus Erythematosus (SLE), with proteinuria being one of the clinical manifestations. The proteinuria pathogenesis is associated with anti-dsDNA antibody and the location of immune complex deposits within the kidney. This study aims to investigate the correlation of the severity of proteinuria with the location of immune complex deposits and the level of anti-dsDNA antibody in LN. Data were collected in cross-section. Fifty-three patients with LN in Saiful Anwar Hospital Malang, who underwent renal biopsy, were included. Hematoxylin-eosin staining and immunofluorescence analysis were used to assign subjects to different histopathological classes and determine the immune complex deposits. The spot urine samples were evaluated using the dipstick method for semi-quantitative proteinuria. The anti-dsDNA antibody levels were evaluated using the enzyme-linked immunosorbent assay (ELISA). Turbidity and enzymatic tests were conducted to elucidate urine protein and creatinine content, respectively. The level of proteinuria is significantly different among the different locations of immune complex based on the dipstick and protein/creatinine methods (p = 0.021 and p = 0.005, respectively). There was a significant correlation between anti-dsDNA antibody level and the severity of proteinuria (r = 0.326 based on dipstick and r = 0.28 based on protein/creatinine method). Thus, proteinuria in LN is determined by anti-dsDNA level and the location of immune complex deposits in the kidney.

Diatoms or phytobenthic are often used as bio-indicators of water quality in freshwater ecosystems such as rivers, but have never been used for monitoring the quality of artificial water ecosystems. The objective of this research is to use the diatom as a bioindicator for measurement the success of phytoremediation process of irrigation water that has status hyper-eutrophic and is polluted from organic materials using polyculture of various local hydromacrophytes through batch culture system. This experimental study was conducted in a greenhouse through planting some local emergent, submerged and floating leaf hydromacrophytes on a 30 L bucket with a given substrate from sand and gravel. The experiment used a completely randomized design with two treatment included phytoremediation model and control in the form of substrate without hydromacrophyte which repeated three times at the same time. The success of phytoremediation model was determined through some biotic diatoms indices (Percentage Pollution Tolerant Value/%PTV, Tropical Diatom Index/TDI and Shannon Wiener Diversity Index) as bioindicator and the improved water physics chemical quality on days 0, six, and 13 after incubation. The results showed that phytoremediation process using polyculture hydromacrophytes through batch culture system for 13 days significantly improving the quality of irrigation water. Based on some biotic diatom indices, the water was improved from heavily organic pollution to moderately organic pollution (%PTV), from hypereutrophic to become eutrophic (TDI) and from moderately polluted become slightly polluted (Shannon Wiener Diversity Index). This results also supported from water physico-chemical parameters. Poly-culture of some local hydromacrophytes for six days significantly decreased the organic matter content of irrigation water was reflected from the decrease concentration of Biochemical Oxygen Demand/BOD (14.79 mg/L to 3.61 mg/L), Total Suspended Solid/TSS (14.6 mg/L to 0.08 mg/L), turbidity (19.97 NTU to 1.46 NTU), nitrate (1.44 mg/L to 0.03 mg/L), orthophosphate (0.24 mg/L to 0.042 mg/L), Total Kjeldahl Nitrogen (TKN) (0.93 mg/L to 0.68 mg/L), and free chlorine (0.09 mg/L to 0.05 mg/L), while concentration of Chemical Oxygen Demand (COD) decreased significantly 13 days after incubation from 48.3 mg/L to18.2 mg/L.
