CONTEXT Herbal remedies are used to treat a large variety of diseases, including blood-related disorders. However, a number of herbal preparations have been reported to cause variations in clotting time, this is mainly by disruption of the coagulation cascade. OBJECTIVE The compiling of plants investigated for effects on the coagulation cascade. METHODS Information was withdrawn from Google...

The aspartic proteases, also called aspartyl and aspartate proteases or acid proteases (E.C.3.4.23), belong to the endopeptidase family and are characterized by the conserved sequence Asp-Gly-Thr at the active site. These enzymes are found in a wide variety of microorganisms in which they perform important functions related to nutrition and pathogenesis. In addition, their high activity and sta...

The whole blood viscosity (WBV) is one of the major independent indicators for the risk of cardiovascular disease, stroke, and peripheral arterial diseases. Furthermore, oxidized LDL molecules are known to cause atherosclerotic plaques in arteries, and it is one of the key components that increase WBV. The present study attempted to reduce WBV by coagulating plasma proteins and lipid molecules ...

A simple method is presented for forming thread-like fibers from highly viscous dextran solutions. Based on the cohesive and adhesive forces between a dextran solution and the substrate to which it is applied, multiple fibers of approximately 10 μm in diameter can be elongated simultaneously. These fibers can be woven into multiple layers to produce fabrics of varying fiber orientations and mec...

A sandwich e.l.i.s.a. method was developed to examine the distribution of lactoferrin in mouse reproductive tract. The lactoferrin concentration was found to be much higher in oviduct, uterus, vagina, vas deferens or epididymis than in serum, but the concentration in ovary, testis, seminal vesicle, prostate or coagulating gland was comparable with that in serum. The existence of lactoferrin in ...

Background: Leaf protein concentrate (LPC) is a cheap and feasible source of high-quality protein. Researchers found the quality LPC similar to first-class food. Tobacco protein-rich leaf but contains high amount nicotine. According studies obtained from tobacco leaves nicotine-free also useful gaining weight in malnourished rats. Methods: Fresh were blended with distilled water different ratio...

PURPOSE We describe the use of chick chorioallantoic membrane (CAM) as a model system for the study of the precision and safety of vitreoretinal microsurgical instruments and techniques. METHODS The CAM was prepared for experimentation with and without its inner shell membrane (ISM) attached for in vivo and in vitro experiments that simulated medical and surgical interventions on the retina. ...

Agents that alter the dynamics of hemostasis form an important part in management of conditions such as atherosclerosis, cerebrovascular disease, and bleeding diatheses. In this study, we explored the effects of heparin and tranexamic acid on the efficiency of blood coagulation. Using optical tweezers, we evaluated the pN-range micro-interaction between coagulating red blood cells (RBCs) by mea...

Since the first description of spontaneous mast cell tumors (mastocytomas) of dogs (2), subsequent studies have been concerned with the morphology and behavior of the neoplastic mast cells in tissue culture (11). Chemical preparations of these tumors have demonstrated considerable quantities of an anti-coagulating substance that is presumably heparin (10). The present study demonstrates the pre...

A direct method is presented for the determination of manganese in whole blood or serum by atomic absorption spectroscopy, using a graphite furnace with a temperature ramp controller. Blood or serum is diluted with an equal volume of a five percent solution of Triton-X100 containing heparin. This prevents the blood from coagulating and produces a solution with a viscosity suitable for injection...
