Baylor U scientists rept isolation and synthesis of thyrotropin releasing factor (TRF), hormone that originates in hypothalamus (part of brain), which in minute amounts causes pituitary gland to release substance called thyrotropin, which acts on thyroid gland, causing it to release thyroid hormone; TRF apparently is ultimate controlling factor in functioning of thyroid gland; scientists believe isolation of TRF will have major importance in diagnosis and treatment of thyroid disorders and will ease process of isolating and synthesizing entire family of other releasing factors in brain that act on pituitary gland; releasing factors are believed to control body's production of growth and male and female sex hormones; possible development of new class of birth control agents linked; researchers who conducted study included Drs R Guillemin, R Burgus, T S Dunn, D Desiderio, W Vale and D Ward; Burgus discusses work of isolating hormone, which was extracted from sheep brains
