Abstract: The present invention relates to a method of treating chronic fatigue syndrome not associated with an HIV infection. In the method of the present invention patients are administered a pharmaceutically acceptable carrier together with(1) a neuropsychiatrically effective amount of a linear peptide of formula (I):R.sup.a -Ser-Thr-Thr-Thr-Asn-Tyr-R.sup.6 (I)whereinR.sup.a is Ala, D-Ala or Cys-Ala-, andR.sup.6 is Thr, Thr-amide, Thr-Cys or Thr-Cys-amide,or a derivative of the peptide or a physiologically acceptable salt thereof; or(2) a neuropsychiatrically effective amount of a linear peptide of formula (II):R.sup.1 -R.sup.2 -R.sup.3 -R.sup.4 -R.sup.5 (II)whereinR.sup.1 is X-Y or Y when Y is Thr-, Ser-, Asn-, Leu-, Ile-, Arg- or Glu-, and X is Cys;R.sup.2 is Thr-, Ser- or Asp;R.sup.3 is Thr, Ser, Asn, Arg, Gln, Lys or Trp;R.sup.4 is Tyr; andR.sup.

Abstract: A method of producing a slub fiber is disclosed in which a metered core yarn is fed into a vortex generator and an effect yarn under continuous low level tension is fed into the balloon formed by the core yarn at the exit of the vortex generator such that the point at which the effect yarn contacts the core yarn balloon is free to move randomly, allowing the said effect yarn to form a randomized slub effect.The combined yarns are then passed through a texturing jet to more permanently bind the yarns together.
