• Apparatus for reducing the functioning lymphocyte population in blood

  A method and system are disclosed for externally treating human blood, with the objective of reducing the functioning lymphocyte population in the blood system of a human subject. According to the method, blood is withdrawn from the subject and passed through an ultraviolet radiation field in the presence of from about 1 nanogram to 100 micrograms per ml of blood, of a dissolved psoralen capable of forming photoadducts with DNA, to thereby effect covalent bonding between the psoralen and the nucleic acid of the lymphocytes, thereby altering the said nucleic acid and inhibiting the metabolic processes of the lymphocytes; and thereupon returning the irradiated blood to the subject. The withdrawn blood may be formed into an extracorporeal stream and flowed through a treatment station whereat the irradiation is effected, as for example by exposure to UV energy in the wave lenght range of from about 3200 to 4000 Angstroms; and such flow process may be conducted on a continuous basis. If desired, at least portions of the treated blood may then be separated, as for example by a continuous centrifuge, before returning the remaining diverted blood to the subject.

  本发明公开了一种从外部处理人体血液的方法和系统，目的是减少人体血液系统中的功能淋巴细胞数量。根据该方法，从受试者体内抽取血液，在每毫升血液中含有约 1 纳克至 100 微克能与 DNA 形成光加合物的溶解补骨脂素的情况下，使血液通过紫外线辐射场，从而实现补骨脂素与淋巴细胞核酸之间的共价键合，从而改变上述核酸并抑制淋巴细胞的代谢过程；然后将经过辐照的血液送回受试者体内。抽出的血液可以形成体外血流，流经一个处理站，在该处理站中进行辐照，例如暴露于波长范围约为 3200 至 4000 埃的紫外线能量中；这种流动过程可以连续进行。如果需要，至少可以将处理过的部分血液分离出来，例如通过连续离心机分离，然后再将剩余的分流血液送回受试者体内。

  Biological compositions are freed of functional polynucleotides by treatment of the biological composition with psoralen derivatives under irradiation conditions in which the proteins retain their original physiological activities and any polynucleotide present is rendered inactive.

  在辐照条件下，用补骨脂素衍生物处理生物组合物，使蛋白质保持其原有的生理活性，而存在的任何多核苷酸则失去活性，从而使生物组合物中的功能性多核苷酸消失。

  A vaccine composition for animals susceptible to infection by canine distemper virus is disclosed. The vaccine comprises an immunologically effective amount of an inactivated canine distemper virus in combination with a non-toxic pharmaceutically acceptable immunologic adjuvant, inactivation of the canine distemper virus being effected by exposure of the virus to long wavelength ultraviolet light ultraviolet radiation or gamma radiation in the presence of a furocoumarin.
