Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
104 words
A method of typically cleansing at least a portion of the human body that may have been brought into contact with body fluid containing human retrovirus which comprises cleansing said portion of the human body with a topical cleansing agent consisting essentially of a cleansing vehicle containing from 2.5 to 2,000 ppm of a compound having saccharic carbon atoms, said compound being dextran sulfate having a molecular weight of from 2,000 to 10,000 wherein said compound has at least 5% sulfur content provided by s-oxoacid groups attached to said saccharic carbon atoms through a linking group of about 14 to about 32 molecular weight.
Claim 2
Independent Claim
104 words
A method of typically cleansing at least a portion of the human body that may have been brought into contact with body fluid containing human retrovirus which comprises cleansing said portion of the human body with a topical cleansing agent consisting essentially of a cleansing vehicle containing from 2.5 to 2,000 ppm of a compound having saccharic carbon atoms, said compound being dextran sulfate having a molecular weight of from 2,000 to 10,000 wherein said compound has at least 5% sulfur content provided by s-oxoacid groups attached to said saccharic carbon atoms through a linking group of about 14 to about 32 molecular weight.
Claim 3
Dependent Claim
16 words
The method according to claim 1, wherein said S-oxoacid groups are sulfo groups (--SO 3 H).
Claim 4
Dependent Claim
26 words
The method according to claim 1, wherein said linking group is selected from the group consisting of an oxo group (--O--) and an imino group (--NH--).
Claim 5
Dependent Claim
14 words
The method according to claim 1, wherein said retrovirus is a human immunodeficiency retrovirus.
Claim 6
Dependent Claim
28 words
The method according to claim 4, wherein said human retrovirus is selected from human T-lymphotropic virus-III, lymphadenopathy associated virus-1, lymphadenopathy associated virus-2, AIDS-related virus and human T-lymphotropic virus-IV.
Claim 7
Dependent Claim
24 words
The method according to claim 4, wherein said human retrovirus is human T-lymphotropic virus-I, human T-lymphotropic virus-II or a causative virus for Kawasaki disease.
Claim 8
Dependent Claim
20 words
The method according to claim 1, wherein said dextran sulfate has inhibitory activity against reverse transcriptase of the human retrovirus.
Claim 9
Dependent Claim
17 words
The method according to claim 1, wherein said dextran sulfate is a sulfuric acid ester of dextran.
Claim 10
Dependent Claim
20 words
The method according to claim 8, wherein said dextran sulfate has at least one hydrogen sulfate group (--O--SO 3 H).
Claim 11
Independent Claim
114 words
A method of topically cleansing at least a portion of the human body that may have been brought into contact with body fluid containing human retrovirus which comprises cleansing said portion of the human body with a topical cleansing agent composition consisting essentially of a compound having saccharic carbon atoms, said compound being dextran sulfate having a molecular weight of from 2,000 to 10,000, wherein said compound has at least 5% sulfur content provided by s-oxoacid groups attached to said saccharic carbon atoms through a linking group of about 14 to about 32 molecular weight and wherein said cleansing agent provide a concentration of 2.5 to 2,000 ppm of said compound on said human.
Claim 12
Independent Claim
114 words
A method of topically cleansing at least a portion of the human body that may have been brought into contact with body fluid containing human retrovirus which comprises cleansing said portion of the human body with a topical cleansing agent composition consisting essentially of a compound having saccharic carbon atoms, said compound being dextran sulfate having a molecular weight of from 2,000 to 10,000, wherein said compound has at least 5% sulfur content provided by s-oxoacid groups attached to said saccharic carbon atoms through a linking group of about 14 to about 32 molecular weight and wherein said cleansing agent provide a concentration of 2.5 to 2,000 ppm of said compound on said human.
Claim 13
Dependent Claim
16 words
The method according to claim 10, wherein said S-oxoacid groups are sulfo groups (--SO 3 H).
Claim 14
Dependent Claim
26 words
The method according to claim 10, wherein said linking group is selected from the group consisting of an oxo group (--O--) and an imino group (--NH--).
Claim 15
Dependent Claim
14 words
The method according to claim 10, wherein said retrovirus is a human immunodeficiency retrovirus.
Claim 16
Dependent Claim
28 words
The method according to claim 13, wherein said human retrovirus is selected from human T-lymphotropic virus-III, lymphadenopathy associated virus-1, lymphadenopathy associated virus-2, AIDS-related virus and human T-lymphotropic virus-IV.
Claim 17
Dependent Claim
24 words
The method according to claim 13, wherein said human retrovirus is human T-lymphotropic virus-I, human T-lymphotropic virus-II or a causative virus for Kawasaki disease.
Claim 18
Dependent Claim
20 words
The method according to claim 10, wherein said dextran sulfate has inhibitory activity against reverse transcriptase of the human retrovirus.
Claim 19
Dependent Claim
17 words
The method according to claim 10, wherein said dextran sulfate is a sulfuric acid ester of dextran.
Claim 20
Dependent Claim
20 words
The method according to claim 17, wherein said dextran sulfate has at least one hydrogen sulfate group (--O--SO 3 H).
