摘要:
New compounds, which we have named the "Leustroducsins" have the formula (I): ##STR1## in which R represents a 5-methylhexanoyloxy group, a 6-methyloctanoyloxy group or a 7-methyloctanoyloxy group, and salts thereof, and may be prepared by fermentation using a microorganism of the genus Streptomyces, especially a strain of the species Streptomyces platensis, such as strain SANK 60191 (FERM BP-3288). These compounds may be used for the treatment or prophylaxis of: adverse reactions resulting from cancer chemotherapy or radiotherapy; infections; cancer; cerebral dysfunction; and fungal infections.

摘要:
A control system for an internal combustion engine that executes post injection, which is capable of accurately estimating the state of dilution of engine oil, thereby properly controlling the amount of oil dilution such that it does not become too large. In an internal combustion engine having an injector that injects fuel into a combustion chamber, post injection is executed in which fuel is injected from the injector during the expansion stroke or the exhaust stroke of the engine, based on a detected operating condition of the engine. The amount of dilution of engine oil diluted with fuel injected by post injection is calculated. The amount of fuel evaporated from the engine oil is calculated. A state of dilution of the engine oil is estimated based on the calculated engine dilution amount and the calculated fuel evaporation amount.

摘要:
A method for purifying an organometal compound by removing oxygen atom-containing compounds included in the organometal compound as impurities is herein disclosed. The method comprises the steps of mixing an organometal compound represented by the following formula: ##STR1## with a crude product including an oxygen atom-containing compound represented by the following formula: R.sub.3-n M.sup.1 (OR).sub.n or R.sub.2-m M.sup.2 (OR).sub.m and an alkylaluminum chloride represented by the formula: X.sub.6-q Al.sub.2 R and then distilling the resulting mixture. In the foregoing formulas, R's may be the same or different and each represents an alkyl group having 1 to 3 carbon atoms; M.sup.1 represents a trivalent metal element; M.sup.2 represents a divalent metal element; n is an integer of 1, 2 or 3; m is an integer of 1 or 2; q is an integer ranging from 1 to 5; and X represents a chlorine atom.
