Acute cholecystitis caused by Clonorchis sinensis.

We are reporting a case of a 43-year-old Chinese male from Hong Kong, who came to see a doctor complaining of acute onset of severe upper abdominal pain. A diagnosis of acute cholecystitis was made and an emergency cholecystectomy was carried out. On opening the common bile duct, lancet-shaped worms were seen emerging from it. About 45 adult worms were collected and sent to the Department of Parasitology University of Malaya for identification. The worms were identified as Clonorchis sinensis. After the operation the patient was treated with praziquantel and he had an uneventful recovery.

Trophic status of Chatri Lake in the vicinity of Amravati city.

Chatri lake is situated a bit away from the busy city. This lake is famous by the name Chatri Talaw. This lake was once used for drinking water purpose. Since 'Upper Wardha Project' came into existence the lake water is not used for drinking purpose. Site is such that it can otherwise be developed as an ecological spot and will be a place of attraction for the people. The present situation is such that, the lake is very fastly receding and becomes shallow due to heavy sedimentation. It appeared from our observations that low sodium and potassium content and reduction of photic zone due to high turbidity resulted in low phytoplankton density in the lake. Thus lake is oligotrophic in nature.

Comparison of calpain and calpastatin activities in skeletal muscle of broiler and layer chickens.

1. The objective of this study was to estimate the difference between broiler and layer chicks in the activities of calpain and calpastatin (inhibitor of calpain) in breast muscle. Differences between broilers and layers in body weight, daily gain at 3 weeks of age and fractional growth rate (FGR) during 2 and 3 weeks of age were statistically significant (P < 0.01). 2. Calpain and calpastatin activities were measured at three weeks of age with alkali-denatured casein as a substrate. The m-calpain (calpain activated by millimolar calcium concentration) activities in units/g muscle and units/mg extractable muscle protein were 0.779 and 0.353 for broilers, and 1.042 and 0.440 for layers, respectively. The calpastatin activities in units/g muscle and units/mg extractable muscle protein were 0.332 and 0.153 for broilers, and 0.262 and 0.112 for layers, respectively. 3. Broilers with high FGR showed low m-calpain and high calpastatin activities. In contrast, layers with low FGR showed high m-calpain and low calpastatin activities. 4. These results suggest that m-calpain and calpastatin activities in skeletal muscle vary between breeds which have different rates of muscle production.
