The plasma fibrinolytic activity, measured in vitro, of 17 healthy normal young males was consistently and equally inhibited by prior ingestion of equal amounts of either a relatively saturated animal fat (butterfat) or a highly unsaturated vegetable fat (safflower oil). This effect was further studied by the addition of purified chylomicrons derived from ingestion of either butterfat, safflowe...

Several procedures have been utilized to elevate plasma free fatty acid (FFA) concentration and increase fatty acid (FA) delivery to skeletal muscle during exercise. These include fasting, caffeine ingestion, L-carnitine supplementation, ingestion of medium-chain and long-chain triglyceride (LCT) solutions, and intravenous infusion of intralipid emulsions. Studies in which both untrained and we...

one of the complications during a routine dental implant placement is accidental ingestion of the implant instruments, which can happen when proper precautions are not taken. appropriate radiographs should be taken to locate the correct position of foreign body; usually the foreign body passes asymptomatically from gastrointestinal tract but sometimes it may lead to intestinal obstruction, perf...

Seven athletes with low lesion paraplegia ingested a 7.6% 648ml glucose drink using two schedules of ingestion (4  162 ml per 20 min & 2  324 ml per 60 min) in a crossover design. Participants exercised at 65% peak oxygen uptake for one hour, followed by a 20-minute performance test. The cardiorespiratory responses during the one-hour tests were similar between trials. Plasma glucose concentr...

In rats with primary retinal degeneration, lens extraction combined with total retinal detachment provided a model for injection of a tracer of colloidal carbon into the subretinal space. Electron microscopy and acid phosphatase cytochemistry were subsequently used to analyze the ingestion of tracer by the retinal pigment epithelium. It was found that the attachment, ingestion, and digestion ph...

The mouse pathogen Mycobacterium lepraemurium is readily phagocytosed by cultured mouse peritoneal macrophages. Ingestion is normally followed by fusion between phagosomes and lysosomes. The influence of some aninonic compounds known to inhibit fusion in other systems was investigated by transmission electron microscopy after ingestion of M. lepraemurium. Fusion was markedly, although temporari...

Health effects of acute exposure • The main routes of exposure to hydrogen chloride are via inhalation, or skin or eye contact and exposure to hydrochloric acid is predominantly by ingestion, or skin or eye contact • Inhalation may cause irritation to nose and upper respiratory tract, ulceration, coughing, chest tightness and shortness of breath. Higher concentrations cause tachypnoea, pulmonar...

1. Folate deficiency is commonly found in alcoholic subjects although the causative mechanism is uncertain. It has been suggested that microsomal enzyme induction resulting from chronic alcohol ingestion might accelerate the rate of folate catabolism thus causing deficiency. 2. By using an experimental animal model to determine the rate of catabolism of [3H]pteroylglutamate (folic acid) by the ...
