Abstract
Abstract A method of determining the oxidizing capacity of a biological liquid (BLOA) which comprises forming the biological liquid into two samples, incubating one of the two samples at a temperature of 10° C. to 40° C. for a period of 4 to 20 hours, treating each of the samples with a reagent made by homogenizing the lenses of mammals, and measuring and comparing the light absorption of the incubated sample and non-incubated reference sample.

Claim 6
Dependent Claim
25 words
The method as claimed in claim 1 incubation is performed at a temperature of 32° C. to 35° C. for a period of 4 hours.
Claim 7
Dependent Claim
92 words
A method for evaluating the potential therapeutic activity of a drug used in the treatment of cataracts which comprise the steps of: taking a first sample of biological liquid from the patient and determining the oxidizing capacity thereof according to claim 1, administering the drug to the patient, taking a second sample of a biological liquid from the patient and determining the oxidizing capacity thereof according to claim 1, and evaluating the therapeutic activity of the drug by measuring the relation in the oxidizing activity of the respective samples of biological liquid.
Claim 8
Dependent Claim
28 words
The method for evaluating the potential therapeutic activity of the drug of claim 6 wherein the drug is administered in the minimum quantity prescribed in the normal dosage.
Claim 9
Dependent Claim
33 words
The method for evaluating the potential therapeutic activity of a drug used in the treatment of cataracts of claim 6 wherein the second sample is taken two hours after administration of the drug.
