The objective of this study was to examine the effects of 6 days of emersion on nitrogen metabolism and excretion in the Chinese soft-shelled turtle, Pelodiscus sinensis. Despite having a soft shell with a cutaneous surface that is known to be water permeable, P. sinensis lost only ~2% of body mass and was able to maintain its hematocrit and plasma osmolality, [Na(+)] and [Cl(-)] during 6 days ...

BACKGROUND Clonorchis sinensis causes chronic cumulative infections in the human hepatobiliary tract and is intimately associated with cholangiocarcinoma. Approximately 35 million people are infected and 600 million people are at risk of infections worldwide. C. sinensis excretory-secretory products (ESP) constitute the first-line effector system affecting the host-parasite interrelationship by...

The WD40-repeat proteins serve as a platform coordinating partner proteins and are involved in a range of regulatory cellular functions. A WD40-repeat protein (CsWD1) of Clonorchis sinensis previously cloned is expressed stage-specifically in the tegumental syncytium of C. sinensis metacercariae. In the present study, interacting proteins with the CsWD1 protein was purified by immunoprecipitati...

Traditionally, the authentication of the traditional Chinese medicines (TCM), Angelica sinensis, is based on slightly different morphological characters and complex compounds. Usually, those methods are simultaneously affected by several factors, leading to subtle and ambiguous results. In this study, the internal transcribed spacer (ITS) regions of A. sinensis and seven other Angelica species ...

To evaluate the prevalence and risk factors of Clonorchis sinensis infection, an epidemiologic survey was performed (3,169 residents; age range: 30-87 years; mean age = 59; 1,973 women) in three areas with different mortality rates of cholangiocarcinoma. C. sinensis prevalence was 2.1% in Chuncheon, 7.8% in Chungju, and 31.3% in Haman, where cholangiocarcinoma incidence rate was 0.3, 1.8, and 5...

Objective: The antiulcer activity of various extracts of Hibiscus rosa sinensis leaves was evaluated in pyloric ligation induced gastric ulcer in albino rats. Method: The leaves extracts were prepared by cold maceration process with petroleum ether, alcohol and water separately. Results: Oral administration of aqueous and alcohol extracts (200 and 400 mg/kg) of Hibiscus rosa sinensis leaves wer...

We have shown in molecular basis that alcoholic tea aroma is mainly formed by endogenous enzymatic hydrolysis of glycosidic aroma precursors during manufacturing. Amounts of alcoholic aroma precursor and glycosidase activity in each part of the tea shoot (Camellia sinensis var. sinensis cv Yabukita and a hybrid of var. assamica & var. sinensis cv Izumi) were indirectly measured by means of a cr...

Oral administration of laboratory cultured mycelia powder of C. sinensis did not show any sign of toxicity as no significant change was observed in organ weight and serological parameters in rats. However, there was a significant increase in food intake, body weight gain and hematological parameters like WBC, RBC, Hb and lymphocytes in treated groups. Histopathology of vital organs also support...

Clonorchis sinensis is one of the most common causes of trematodiasis that is caused by the ingestion of raw fish contaminated with infective cysts. The adult flukes are predominantly present in the intrahepatic bile ducts, but occasionally they may be found in the pancreatic duct and extrahepatic bile ducts. The clinical manifestations depend on the number of flukes, the period of infestation,...

biliary liver flukes are common parasites in some regions of the world where consumption of raw fresh-water fish is a cultural practice. clonorchis sinensis and opisthorchis species are the major biliary liver flukes associated with human disease. some of these parasites are highly associated with cholangiocarcinoma. this report describes a clinically and epidemiologically unsuspected liver flu...
