Method for the treatment of systemic mycosis of mammals comprises administering (S)-2-amino-5-hydroxy-4-oxopentanoicacid in a therapeutically effective amount to said mammals suffering from mycosis, typically candidosis.
摘要:
The novel antibiotics represented by the formula ##STR1## wherein either (a) R.sup.1 is hydroxy and R.sup.2 is hydrogen, or (b) R.sup.1 is methoxy and R.sup.2 is hydroxy, and the salt thereof, are produced by the cultivation of the organism Streptomyces hygroscopicus TM-531 under aerobic conditions. They are separated from coproduced Antibiotic TM-531 as disclosed in U.S. Pat. No. 4,269,971 and from each other by chromatography on silica gel.
摘要:
Novel lonomycin derivatives, prepared by reacting lonomycin or its salt with an alkali or an alkali metal borohydride, show antibacterial, antiviral and antiprotozoal activity, and have decreased toxicity as compared with lonomycin.
摘要:
A combustion heater includes an inner tube having a supply passage for combustion gas in an inner portion, and an outer tube disposed to provide a separated combustion space in an outer periphery of the inner tube. A hole part for ejecting the combustion gas is formed on a tube wall of the inner tube and combustion gas is ejected with ejection characteristics such that circulating flow is formed on the periphery of a stagnation point. According to this combustion heater, a stable flame can be formed without increasing costs and the heating efficiency can be improved.
摘要:
Includes a low flow-rate region (R2) that is disposed on an upstream side of a combustion region (R1) within a second pipe (2), and that has a relatively slow flow-rate of combustion gas (G1) within the second pipe, and a flame kernel formation unit (3a) is disposed in the low flow-rate region.
摘要:
A combustor comprises a fuel flow path (10) which is a flow path for fuel (G1) and which is capable of emitting the fuel to its own exterior; an air flow path (20) which is a flow path for air (G2) and which is capable of emitting the air to its own exterior; and an exhaust gas flow path (30) which has a combustion region (R) wherein an air-fuel mixture that mixes the fuel and the air is burned and which constitutes an exhaust flow path for burned gas that is produced by combustion; wherein the fuel within the fuel flow path and the air within the air flow path are heated by the heat of the burned gas, and the air-fuel mixture is constituted by mixing the fuel emitted from the fuel flow path and the air emitted from the air flow path in the exhaust gas flow path.
摘要:
A combustion heater (1) comprises an inner tube (20) having a supply passage (21) for a combustion gas (G) therein and an outer tube (10) disposed around the outer periphery of the inner tube with a combustion space (30) interposed therebetween. A hole part (24) for jetting the combustion gas is formed in the wall of the inner tube. A radiation promoting surface (20B) is formed on the outer periphery of the inner tube. By the structure, the excessive heating of the inner tube is suppressed, and the heating efficiency of the combustion heater is increased.
