Phytoplankton species composition, seasonal variation and the factors effecting the variation were studied in this study one-year period, from June 2010 to May 2011. Water samples were collected monthly from four stations. Algae of the stream was determined by the enumaration and identification of the collected samples. A total of 53 phytoplankton taxa were determined, consisting of Bacillariophyta (79%), Chlorophyta (9%), Cyanobacteria (6%), Euglenozoa (4%) and Cryptophyta (2%). Bacillariophyta dominated mostly in species variety. Diatoms are commonly used as bioindicator organisms for evaluating especially freshwater quality. Trophic diaton index (TDI) provides information about trophic levels of the aquatic ecosystem.

The aim of this study was to investigate whether thiamine pyrophosphate (TPP) has biochemical and histological preventive effects on oxidative liver damage induced by paracetamol (APAP). Rats were divided into the following groups: healthy control (HG), APAP (AG, 1500 mg/kg, orally), thiamine pyrophosphate (TPPG, 100 mg/kg, intraperitoneally), APAP+NAC (ANAC, 100 mg/kg, intraperitoneally), APAP+TPP (ATPG) and APAP+NAC+TPP (ANTG). Oxidant, antioxidant parameters, liver function tests and histological assessment were performed between groups.
