摘要:
Administration of a resistance imparting agent characterized by comprising an organogermanium compound as an effective component shown by the following formula (I); ##STR1## (wherein A and B denote hydrogen or lower alkyl groups such as methyl and ethyl groups, R denotes a combination of one or two atoms or groups shown by A or B, and X denotes an oxygen or nitrogen atom) in patients having low pulmonary function (35 examples of a group to which the agent was administered, 34 examples of an untreated group) showed that the number complaining of cold syndrome was 13 in the first group and 30 in the second group, which the total number of days during which remedies were used by the first group for cold syndrome was 79 days (of a total possible of 4635 days) compared with 295 days (of a total possible of 4860 days) for the untreated group, and that patients having low pulmonary function were apparently endowed with resistance to cold syndrome. Furthermore, no remarkable side-effects were observed.
