Cultured shrimp are often exposed to different toxic products during rearing practices that may affect survival and quality of the product. An evaluation of the effects of paralytic shellfish toxins (PSP) from species of Gymnodinium catenatum in white leg shrimp (Litopenaeus vannamei) has been carried out in this study. Death was observed at doses > 5.0 MU (equivalent to 1.1 mug/g of STX), whil...

GANGRENE and eyanosis of an extremity, due to thrombophlebitis with massive venous occlusions, is an uncommon condition and is often confused with primary arterial oeclusive disease. With massive venous occlusion and the associated arterial venospasm the blood flow may be so impeded to an extremity that cyanosis and eventually gangrene may occur. The recognition of this is important, since this...

Prawn, shrimp and crabs sold in Japan are mostly imported from overseas. Detection of irradiated crustaceans is very important for quality assurance. In this study, we used ESR to detect radiation-induced radicals after irradiation of prawn, shrimp and crabs of major species. No radiation-induced radicals were detected in prawn (black tiger prawn) or shrimp (white leg shrimp). Radiation-induced...

In a prospective study, nine patients with phlegmasia caerulea dolens (PCD) related to iliac occlusive thrombosis were treated with intravenous thrombolysis. After thrombolysis, despite no significant improvement in the Marder score value, progression to venous gangrene, major hemorrhage or death was not observed and no amputation was needed. Intravenous thrombolysis should be seriously conside...

Electron microscopic observations on ultrathin sections of the red thoracic flightmuscles and white leg muscles of Hydrophilus and Dytiscus are reported. In red muscle-fibres with high values in frequency of contraction, oxygen consumption, and dehydrogenase activity, the single fibrils are completely surrounded by huge mitochondria. Tracheoles penetrate the sarcolemma and supply the mitochondr...

Phlegmasia cerulea dolens (PCD) is one of the most critical disorders of acute deep vein thrombosis in that it can cause permanent disability secondary to the compartment syndrome. Although several etiological factors have been proposed, PCD after coronary artery bypass surgery is extremely rare and its definitive pathophysiology is still under debate. We herein present a case of PCD that resul...

Background Venous thromboembolism in pregnancy remains one of the leading causes of morbidity and mortality. Case A young, gravid patient presented with a cyanotic, edematous left lower extremity with no distal pulses palpable. She was emergently taken to the operating room and was found to have extensive iliofemoral thrombosis requiring femoral angioplasty and embolectomy with 43.7-rad intraop...

Phlegmasia cerulea dolens (PCDs) is a rare and serious complication of massive deep venous thrombosis of the lower extremities, which has a high mortality rate. It is characterized by the sudden onset of severe leg pain, massive edema, cyanosis, venous gangrene, compartment syndrome and arterial compromise, often followed by pulmonary embolism and death. We report one case of a long distance dr...
