Abstract
Abstract Disturbances in circadian rhythms of bodily performance and function, as may occur for example in transfer of work patterns from day to night-shift, or rapid crossing of several time zones in an aircraft ("jet lag") are treated by administration of melatonin. Alleviation or prevention of ill effects associated with disturbance of circadian rhythms is achieved by administration of melatonin in specified ways which are varied to suit particular needs and circumstances.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
51 words
A method of alleviating the effects of disturbed circadian rhythms on bodily performance and function in a human subject comprising administering orally to said subject melatonin at a time when the subject's sleep cycle should commence, the amount of melatonin being sufficient to re-entrain the disturbed circudian rhythms of said subject.
Claim 2
Independent Claim
51 words
A method of alleviating the effects of disturbed circadian rhythms on bodily performance and function in a human subject comprising administering orally to said subject melatonin at a time when the subject's sleep cycle should commence, the amount of melatonin being sufficient to re-entrain the disturbed circudian rhythms of said subject.
Claim 3
Independent Claim
56 words
A method of entraining circadian rhythms to a predetermined cycle having a periodicity of approximately 24 hours in a human subject comprising administering orally to said subject melatonin at a time which coincides with the sleep phase of the predetermined cycle, the amount of melatonin being sufficient to entrain the circadian rhythms to said predetermined cycle.
Claim 4
Independent Claim
56 words
A method of entraining circadian rhythms to a predetermined cycle having a periodicity of approximately 24 hours in a human subject comprising administering orally to said subject melatonin at a time which coincides with the sleep phase of the predetermined cycle, the amount of melatonin being sufficient to entrain the circadian rhythms to said predetermined cycle.
Claim 5
Dependent Claim
31 words
A method according to claim 2 wherein said oral administration is maintained at approximately 24 hour intervals at least until the subject's circadian rhythms have been entrained to the predetermined cycle.
Claim 6
Independent Claim
57 words
A method of alleviating the effects of disturbed circadian rhythms due to undergoing a rapid change in time zones comprising administering orally to a human subject melatonin at a time when the subject's sleep phase should occur in a predetermined time zone, the amount of melatonin being sufficient to re-entrain the disturbed circadian rhythms of said subject.
Claim 7
Independent Claim
57 words
A method of alleviating the effects of disturbed circadian rhythms due to undergoing a rapid change in time zones comprising administering orally to a human subject melatonin at a time when the subject's sleep phase should occur in a predetermined time zone, the amount of melatonin being sufficient to re-entrain the disturbed circadian rhythms of said subject.
Claim 8
Independent Claim
73 words
A method of alleviating the effects on circadian rhythms of a rapid transition from one time zone to any number of ther time zones in a human subject comprising administering orally to said subject melatonin at a time chosen to be the subject's sleep phase, the amount of melatonin being sufficient to alleviate the effects on circadian rhythms of a rapid transition from one time zone to any number of other time zones.
Claim 9
Independent Claim
73 words
A method of alleviating the effects on circadian rhythms of a rapid transition from one time zone to any number of ther time zones in a human subject comprising administering orally to said subject melatonin at a time chosen to be the subject's sleep phase, the amount of melatonin being sufficient to alleviate the effects on circadian rhythms of a rapid transition from one time zone to any number of other time zones.
Claim 10
Independent Claim
73 words
A method of alleviating the effects on circadian rhythms of a rapid transition from one time zone to a second time zone in a human subject comprising administering orally said subject melatonin at a time when the subject's sleep phase should occur in the second time zone, the amount of melatonin being sufficient to alleviate the effects on circadian rhythms of a rapid transition from one time zone to a second time zone.
Claim 11
Independent Claim
73 words
A method of alleviating the effects on circadian rhythms of a rapid transition from one time zone to a second time zone in a human subject comprising administering orally said subject melatonin at a time when the subject's sleep phase should occur in the second time zone, the amount of melatonin being sufficient to alleviate the effects on circadian rhythms of a rapid transition from one time zone to a second time zone.
Claim 12
Independent Claim
57 words
A method of alleviating the effects on circadian rhythms of rapidly altering the 24 hours routine in a human subject comprising administering orally to said subject melatonin at a time that coincides with the sleep phase within a new 24 hour routine, the amount of melatonin being sufficient to re-entrain the disturbed circadian rhythms of said subject.
Claim 13
Independent Claim
57 words
A method of alleviating the effects on circadian rhythms of rapidly altering the 24 hours routine in a human subject comprising administering orally to said subject melatonin at a time that coincides with the sleep phase within a new 24 hour routine, the amount of melatonin being sufficient to re-entrain the disturbed circadian rhythms of said subject.
Claim 14
Independent Claim
68 words
A method of alleviating the effects on circadian rhythms of living in an environment substantially free of zeitgebers of 24 hour periodicity comprising orally administering to said subject melatonin at a time that coincides with the desired sleep phase of the subject, the amount of melatonin being sufficient to alleviate the effects on circadian rhythms of living in an environment substantially free of zeitgebers of 24 hour periodicity.
Claim 15
Independent Claim
68 words
A method of alleviating the effects on circadian rhythms of living in an environment substantially free of zeitgebers of 24 hour periodicity comprising orally administering to said subject melatonin at a time that coincides with the desired sleep phase of the subject, the amount of melatonin being sufficient to alleviate the effects on circadian rhythms of living in an environment substantially free of zeitgebers of 24 hour periodicity.
Claim 16
Independent Claim
47 words
A method of alleviating the effects of a disturbance in the body temperature circadian rhythm in a human subject comprising administering orally to said subject melatonin in an amount sufficient to alleviate the effects of a disturbance in the body temperature circadian rhythm in a human subject.
Claim 17
Independent Claim
47 words
A method of alleviating the effects of a disturbance in the body temperature circadian rhythm in a human subject comprising administering orally to said subject melatonin in an amount sufficient to alleviate the effects of a disturbance in the body temperature circadian rhythm in a human subject.
Claim 18
Independent Claim
57 words
A method of entraining a body temperature circadian rhythm to a predetermined cycle having a periodicity of 24 hours in a human subject comprising administering orally to said subject melatonin, the amount of melatonin being sufficient to entrain a body temperature circadian rhythm to a predetermined cycle having a periodicity of 24 hours in a human subject.
Claim 19
Independent Claim
57 words
A method of entraining a body temperature circadian rhythm to a predetermined cycle having a periodicity of 24 hours in a human subject comprising administering orally to said subject melatonin, the amount of melatonin being sufficient to entrain a body temperature circadian rhythm to a predetermined cycle having a periodicity of 24 hours in a human subject.
