CO2 incubator ozone sterilization device

PROBLEM TO BE SOLVED: To provide an apparatus that ensures sterilization of a COincubator, has no leakage of fed ozone gas to the outside, uniformly circulates ozone in a storage and constantly and continuously controls an ozone concentration.SOLUTION: The apparatus for ozone sterilization of a COincubator includes: a sterilization tent 1 with an airtight hole 8a for airtightly protruding a leading end part of a tube connection part 14a provided in the COincubator 11 to the outside and a discharge part 9a for discharging ozone gas to the outside, for covering the COincubator 11 airtightly; an ozone gas generator 18 for applying circulating sterilization to the inside and the outside of the COincubator 11 covered by the sterilization tent 1 by pressure-feeding the ozone gas to the tube connection part 14a; and an ozone gas neutralization unit 26 for neutralizing and eliminating the ozone gas discharged from the discharge part 9a.

POTENTIAL BILE ACID METABOLITES. X. SYNTHESES OF STEREOISOMERIC 3,7-DIHYDROXY-5α-CHOLANIC ACIDS

New synthetic routes to allochenodeoxycholic (3α,7α-dihydroxy-5α-cholanic) and alloursodeoxycholic (3α,7β-dihydroxy-5α-cholanic) acids, and their stereoisomers are described.Treatments of allo 7α-hydroxy-3β-tosyloxy ester with N,N-dimethylformamide and of allo 7α-mesyloxy-3β-tosyloxy and 3β-cathyloxy-7α-mesyloxy esters with potassium superoxide-crown ether afforded the desired 3α,7α-, 3α,7β-, and 3β,7β-dihydroxy stereoisomers, respectively, in high yield.Highperformance liquid chromatography was of key importance in characterizing the compounds and determining their purity.Keywords--bile acid; allo bile acid; 3,7-dihydroxy-5α-cholanic acid; allochenodeoxycholic acid; alloursodeoxycholic acid; N,N-dimethylformamide reaction; potassium superoxide-18-crown-6 ether reaction; HPLC
