Isolation of rat islets of Langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of Hanks' solution into the common bile duct. The identification of the islets was done by techniques including the use of a stereomicroscope against a black background. Vital staining was done by an injection of neutral red solution through t...

The capacities of Procion Red HE-3B and Cibacron Blue F3G-A immobilized to Sepharose CL-4B and Matrex 201R for NAD+-, NADP+- and NAD(P)+-dependent dehydrogenases were measured. Procion Red HE-3B columns retarded NADP+-dependent dehydrogenases more effectively than NAD+-dependent dehydrogenases, whilst immobilized Cibacron Blue F3G-A retarded NAD+-dependent dehydrogenases more effectively than N...

We investigated the effects of laser excitation wavelength on water-window emission lines of laser-produced boron-nitride plasmas. Plasmas are produced by focusing 1064 nm and harmonically generated 532 and 266 nm radiation from a Nd:YAG laser on BN target in vacuum. Soft x-ray emission lines in the water-window region are recorded using a grazing-incidence spectrograph. Filtered photodiodes ar...

In 1930 Amako reported that as cultures of Serratia marcescens grew old their color changed from red to dark violet. He postulated that the change was associated with the pathway of pigment formation in the microorganism. Weiss (1949) observed a similar color change. Colonies growing on agar were orange-red in color at the end of 24 to 48 hr, but as they grew older the color changed to red-purp...

m. Krypton laser photocoagulat on has been demonstrated to be efficient in the treatment of juxtafoveal well-defined choroidal new vessels in AMD. The efficacy of two different wavelengths frequency doubled Nd-Yag Laser (FDYL) and krypton red (KR) was compared in the treatment of extrafoveal and juxtafoveal well-defined choroidal neovascularization (CNV) secondary to A.M.D. &$,&Q&. 38 eyes were...
