Seeding Introduction of microorganisms (such as ALKEN CLEAR-FLO 1000 series for aquaculture, 4000 series for grease, and 7000 series for industrial and municipal wastewater) into a biological oxidation unit to minimize the time required to build a biological sludge. Also referred to as inoculation with cultured organisms. 

A method of assessing the toxicity of implants has been proposed based on the effects on cell ultrastructure in organ cultures, on cell surface characteristics, and cell population doubling times. The effects have been correlated with hemorrhage, fibrosis, and necrosis, respectively (103). Poly-e-caprolactone was stated to give minimal tissue reaction and could not be scored in these tests.

Biopsy or blood specimens may be cultured for Leishmania spp. or T. cruzi with Novy-MacNeal-Nicolle (NNN) medium. Biopsy specimens are ground in a small amount of saline. Biopsies from skin lesions or other tissues which may contain bacteria may have penicillin (0.1 ml of 1,000 U/ml) added to the medium with the inoculum. The inoculum is 1 drop of ground tissue or blood. Incubate the culture at room temperature (22°C), and at days 3 and 7, examine a direct mount of liquid from the bottom of the slant at x400 magnification. These cultured organisms are potentially infective for humans. 

In some cases, cell culture monolayers can not be obtained but whole organs, or pieces of organs, can be cultured. Such organ cultures may still be useful in virus research, since they permit growth of viruses under more or less controlled laboratory conditions. 

Sugg and Hehre43 also obtained precipitin reactions with dextran or with sterile filtrates of sucrose broth cultures of L. mesenteroides (designated for convenience strain A) and not only anti-Leuconostoc sera, but also pneumococcus Types II, XII and XX antisera. Leuconostoc organisms cultured on D-glucose broth neither stimulated the production of dextran-reactive antibodies in rabbits, nor absorbed dextran-reactive antibodies from sera, as did organisms cultured on sucrose. Absorption with the homologous bacteria (Leuconostoc, pneumococcus Types II,... 

In BA metabolism, the procarcinogenic BA trans-3.4-dihydrodiol (26) constitutes 1.5-4% of all the metabolites formed by rat liver microsomes (27) and a major component of the free dihydrodiols formed by mouse skin maintained in short-term organ culture (28). In this system (28). the noncarcinogenic dihydrodiols may be preferentially removed by conjugation reactions to yield water soluble products.

Haul At 24 h in organ culture we find that RyR2 has been up-regulated by a factor of two or three. 

Hellstrand With regard to the question of what ryanodine is doing, if you put it onto a muscle it eliminates most SR Ca2+ release, because it opens up the SR Ca2+ channels and there is some level of communication between the stores. If you put ryanodine there you essentially kill InsP3-induced responses as well. In organ culture we have found that if you culture in the presence of ryanodine for a couple of days, the InsP3-induced release reappears, whereas there is still no ryanodine-induced release, and Ca2+ waves occur (Dreja et al 2001). We know that mitochondrial activity affects the properties of Ca2+ waves, so there is a Ca2+-dependent modulation of SR release on this level which thus presumably involves InsP3 receptors and not RyRs. It is very hard to distinguish these two receptor populations in the way they interact on the SR.
