From June 6 to nine, 1976, approximately one hundred forty members (physiologists, chemists, ecologists, animal behaviorists, and psychologists) accrued within the Gideon Putnam inn at Saratoga Springs, long island for a symposium entitled "Chemical signs in Vertebrates". the focal point of this symposium, subsidized through the USA nationwide technological know-how origin, used to be on chemical communique in better animals, such a lot significantly mammals. This incorporated the chemical nature, construction, and reception of chemical indications, and their modulating results on habit. just about all the world's laboratories operating during this region have been represented. It was once the 1st assembly of its style, and even though the physiological elements of style and scent at the one hand and bug pheromones at the different have formerly been taken care of in numerous advantageous symposia, they've got no longer ahead of been handled as a again­ drop to chemical communique in vertebrates. the sphere of insect pheromones is easily constructed, with 1000's of energetic compounds pointed out. against this, in vertebrates in basic terms six mammalian phero­ mones in as many species have been pointed out chemically by way of 1976.

The glandular area disappeared after castration, but treatment with testosterone propionate restored it to normal in a few days. Treatment of mature ovariectomized females with estradiol benzoate and progesterone appeared to diminish sebaceous development. APOCRINE GLANDS The Apocrine Glands of the Rabbit The structure and function of the anal, inguinal and submandibular (chin) glands of the rabbit have been described in detail by Mykytowycz (1966a,b,c) who showed that growth of the glands was inhibited by castration during early life.

Lactic acid is formed and vaginal pH is lowered. Volatile fatty acids may BACTERIA AS A SOURCE OF CHEMICAL SIGNALS IN MAMMALS 39 also be formed. , 1972). It is implied that such volatile fatty acids have a similar function in other primates and man. Several species of Lactobacillus with Staphylococcus a1bus act together in generating these acids (Michael et a1, 1975). Preti and Huggins (1975) have critically discussed these findings in relation to man and have documented the occurrence of other classes of odorous compound in human vaginal secretion.
