The cladoceran Diaphanosoma celebensis Stingelin is reported on for the first time from Indian waters (Mandovi estuary, Goa). Amictic females were maintained in
the laboratory (temperature 24 ± 1 °C and salinity 17 psu) for three successive generations in order to follow the parthenogenetic
reproductive behaviour, growth, survival and neonate production. The mean life span and body length of adult females in the
three generations showed some variations and ranged from 9 to 12.5 d and 842 to 932 μm, respectively. The mean length of the
neonates produced also varied (283 to 446 μm) in the three generations. Cladoceran preference for three phytoplankton food
sources, i.e. Isochrysis galbana (Parke), Chaetoceros calcitrans (Paulsen) and Tetraselmis gracilis (Kylin), was determined. Growth was faster in the initial stage with all three diets but slowed down in later life. Increased
food concentrations resulted in higher neonate production but reduced the life span of females. However, long-term feeding
experiments revealed that the percentage survival was high with I. galbana and low with C. calcitrans.

A study on the toxicokinetic behavior, metabolism of chlorpropham, and its effect on cytochrome P450 from liver microsomes was carried out in albino rats after a single and consecutive oral administration at 500?mg?kg?1 body weight for 10 and 20 days. Chlorpropham was detected in the blood at 0.08?h (11.43?±?1.72?µg?mL?1) reaching a maximum concentration at 2?h (30.90?±?2.55?µg?mL?1) and a minimum at 48?h (1.95?±?0.20?µg?mL?1) after a single oral administration of 500?mg?kg?1. The absorption rate constant (K a) was 0.66?±?0.48?h?1. The Vd area (18.01?±?2.78?L?kg?1) and t 1/2 β (12.23?±?1.96?h) values suggested a wide distribution and long persistence of the compound in the body, respectively. The higher ClR (0.82?±?0.00?L?kg?1?h?1) compared to ClH (0.18?±?0.02?L?kg?1?h?1) value indicated that a major portion of chlorpropham was excreted through the urine (30%) compared to the faeces (2.81%). Chlorpropham residue was detected in all tissues of rat at 0.25?h while its metabolite, meta-chloroaniline was detected in liver, kidney, heart, lung, and spleen tissue at 0.25?h. Meta-chloroaniline was not detected in skeletal muscle, brain, fat, and stomach tissue at any time of the observation period. Maximum concentrations of chlorpropham and meta-chloroaniline were detected at 2?h (except in the spleen), and minimum concentrations of chlorpropham at 24 (heart, lung, spleen, skeletal muscle, and stomach) and 48?h (liver, kidney, brain, and fat tissue) respectively; and meta-chloroaniline at 24?h (except heart and spleen). The tissue half-life of chlorpropham in rat varied from 3.80 to 11.60?h. Repeated oral administration of chlorpropham at 500?mg?kg?1 for 10 and 20 days caused an induction of the liver microsomal pellet of rat. 相似文献
