AIMS To evaluate the effect of high dose stereotactic radiotherapy on the ocular blood flow of patients with uveal melanoma. METHODS Colour Doppler imaging (CDI) was used to measure blood flow velocity and vascular resistance in the ophthalmic, short posterior, and central retinal arteries of nine patients suffering from uveal melanoma. The measurements were taken before, 6 months, 1 year, an...

Lipoproteins of the blood have been shown to be retained in the arterial wall selectively at sites of increased permeability, and they also remain in the living corneal stroma following injection in-native plasma or serum.l', In these sites they elicit a lipophagocytic, mononuclear cell, and fibroblastic reaction that simulates morphologic features of the early atherosclerotic plaque.1" These o...

. which have been named transcobalamin 1 and 2 by Hall and Finkler.4 \Vhen serum which contains radioactive vitamin B12 is filtered through sephadex, the radioactivity appears in the effluent in fractions corresponding to molecular weights of 121,000 and 36,000. It has been assumed that these fractions correspond to association of the B12 with TC1 and TC2, respectively. It has been reported tha...

Insoluble blood group substances prepared by copolymerization of soluble blood group substances with N-carboxy-L-leucine anhydride were used to absorb blood group antibodies from two human, high-titered anti-A sera. After the absorbants were washed free of nonspecific serum proteins, blood group antibodies were eluted either with pH 3.62 acetate buffer, or at neutral pH with monosaccharide hapt...

Preliminary investigations were carried out to evaluate the antidiabetic effects of the leaves of O. stamineus extracted serially with solvents of increasing polarity (petroleum ether, chloroform, methanol and water); bioassay-guided purification of plant extracts using the subcutaneous glucose tolerance test (SbGTT) was also carried out. Only the chloroform extract, given at 1 g/kg body weight...

objective: the use of drugs with herbal origin is increasing for treatment of gastrointestinal (gi) disorders. rosa damascena (r. damascena) is a well-known plant suggested to have beneficial effect on gi system. in this study, the effect of aqueous fraction of r. damascena on the contractionsofisolated guinea pig ileum was investigated. materials and methods: aqueous fraction of plant was obta...

background : within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of annona senegalensis leaf extract and its 4 fractions against anopheles gambiae and culex quinquefasciatus were evaluated in the laboratory conditions. methods : ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while ...

Harvey Jon Schiller, MD The article by Sniecinski et al. (1) on the treatment of two Jehovah’s Witnesses with coagulopathy presents a laudable approach toward improved communication with patients who may offer a rather unique medical challenge. Three aspects of this paper merit comment. First, the paper highlights how far we have come in the past few decades in the treatment of Jehovah’s Witnes...

Glycerophospholipid and sphingolipid species and their bioactive metabolites are important regulators of lipoprotein and cell function. The aim of the study was to develop a method for lipid species profiling of separated lipoprotein classes. Human serum lipoproteins VLDL, LDL, and HDL of 21 healthy fasting blood donors were separated by fast performance liquid chromatography (FPLC) from 50 mic...
