SummaryAn 8-day rat levator ani muscle assay for myotrophic activity is presented. Preliminary steroid screening results indicate that 19-nortestosterone and other 19-nor analogs of androgens promise to be effective protein-anabolic, and relatively weak androgenic agents. Using the same dose levels of 19-nortestosterone and testosterone, equal myotrophic responses were produced, yet 19-nortestosterone showed only weak androgenic activity and testosterone exhibited strong androgenic activity. Androsterone possesses relatively strong androgenic and only weak myotrophic activity.

Summary 1.Injection of 0.63 mg 19-nortestosterone into eggs prevents differentiation of the bursa Fabricii. Chickens resulting from such treatment were unable to produce precipitins when challenged with a single intravenous injection of BSA at 6 or 22 weeks of age. 2.Chickens surgically bursectomized at 1 and 2 weeks of age along with intact controls were challenged with BSA at 6 and 12 weeks of age. Antibody response of the bursectomized groups was significantly lower than the control group. The responses of age did not differ from one another. 3.Chickens bursectomized at 1, 5 and 10 weeks of age were injected with BSA at 22 weeks of age and were reinjected at 34 weeks of age. The response of chickens bursectomized at 1 week of age was significantly less than the control response, whereas bursectomy at 10 weeks of age had little or no effect on the response at 22 or 34 weeks of age. Bursectomy at 5 weeks appeared to decrease antibody production at 22 weeks but was without apparent effect at 34 weeks. 4.Surgical bursectomy had no effect on body weight. The hormonal injection of the incubating eggs produced birds weighing less than the controls and in generally poor health. Mortality in the hormone treated birds was high.

Nidation of embryos was delayed from 1 to 45 days in rats ovariectomized on the 3rd day after mating, by subcutaneous injection of 4 mg of progesterone per day. Implantation was delayed until such time as 1 μg of estrone per day was given in addition to the progesterone. Recovery of blastocysts from one horn of the uterus during progesterone treatment and subsequent implantation of the embryos in the other horn induced by the progesterone-estrogen indicates that the embryos are maintained in the uterus in a viable, but resting condition during progesterone treatment. If rats were ovariectomized on the 3rd day and untreated for 8 days, nidation of embryos was not observed when progesterone and estrogen was initiated on the 9th day and given for the next 5 to 12 days. Rats ovariectomized on the 4th day after mating were variable in their response to 4 mg of progesterone, some exhibited delay others implanted at the normal time. Delayed nidation up to at least 3 days was obtained in hypophysectomized rats when they were injected only with 4 mg progesterone per day.

Melatonin in beeswax was implanted in male weasels (Mustela erminea). Brown weasels and white animals undergoing the spring change to the brown pelage and reproductive activity molted, grew a new white coat, and became reproductively quiescent after treatment. Controls retained or acquired the brown coat and developed or maintained enlarged testes. Treated weasels with pituitary autografts under the kidney capsule grew brown hair after hair growth was initiated by plucking. It is suggested that the pineal gland product, melatonin, initiates changes in the central nervous system and endocrines which result in molting, growth of the white winter pelage, and reproductive quiescence in the weasel.

0.63 mg. of 19-nortestosterone in 0.1 ml. of corn oil, when injected into the fertilized eggs of the white leghorn hybrid strain of chickens, “Wisco-white,” on the 5th day of incubation, completely inhibits the development of the bursa of Fabricius in both sexes. In the normal chick the bursal primordium appears as a proliferated epithelial mass dorso-caudal to the embryonal cloaca on the 5th day of incubation. By 168 hours of incubation it forms a tubular structure; its terminal end enlarges into a bursal vesicle on the 10th day and becomes lymphoidal by the 15th day. The bursa is fully formed and lymphoidal in 17- day old chick embryos. In 19-nortestosterone-treated embryos the bursal primordium becomes highly vacuolated. Later it remains as a convoluted, short duct without forming the bursal vesicle. Thus the hatched chicks arc bursaless. The secondary effects of this hormone on the rectal complex are the stunted growth of the ventral anal lip, increase of musculature in the dorsal lip and an attenuated proctodial canal with very few anal mucoid glands.

The eosinophil cell of the blood was first described over 100 years ago (Wharton Jones, 1846), and since then has been the subject of many morphological, cytological, and physiological investigations. However, despite the vast array of publications and reviews, the actual function of this cell in health or disease still eludes the investigator (Kirk, 1942; Bethell, Sturgis, Rundles and Meyers, 1946). A number of comprehensive studies have been made during the last 17 years but most of the investigations were carried out either in man or the guinea pig. Work in other animals seems to have been chiefly of a tabulative and descriptive nature (Scarborough, 1930). In man, an increase in the number of circulating eosinophils has been correlated with allergy, parasitic infection, skin diseases, and a number of other disorders. In the guinea pig the eosinophils are associated with foreign protein reactions such as anaphylaxis and immunity. (For extensive references and reviews see: Schwarz, 1914; Ringeon, 1938; Rud, 1947; and Samter, 1949.)

Graded doses of hydrocortisone, cortisone, corticosterone and diethylstilbestrol were administered to 2-week old cockerels for 7 days and the amount of fat in depots, blood and liver was determined. Hydrocortisone and corticosterone inhibited growth, increased carcass fat and blood and liver lipids. Hydrocortisone is the more potent of the two compounds. Cortisone had no effect on growth or fat content at any of the doses used. Diethylstilbestrol increased blood and liver lipids and stimulated fat deposition without inhibiting growth.

Summary Removal of the bursa of Fabricius at 1 day of age effectively prevents a large percentage of the animals from producing precipitins to bovine serum albumin (BSA) when inoculations are made to 20 weeks of age. Bursectomy at 10 days is less effective. Two steroid hormones, 19-nortestosterone and 17-ethyl-19-nortestosterone, administered on the 12th or 13th day of incubation, cause a 5- to 20-fold reduction in bursal weight. Correspondingly, precipitin production against BSA is grossly impaired. Spleen, thymus and body weights were not consistently affected.

Ten-week-old gray leghorn cockerels with ureters surgically exteriorized so that 24-hour samples of feces free urine could be collected were treated with DCA, cortisone acetate and ACTH. The stress of surgically exteriorizing the ureters produced reduction in weight gains and an increased excretion of electrolytes and nitrogenous wastes on days 3 and 4 following the surgery. In addition there was some adrenal hypertrophy. DCA treatment resulted in polyuria, polydipsia, sodium and potassium retention, and an increase in thiocyanate space. Cortisone acetate caused loss in weight, polyuria and increased excretion of sodium, potassium, total nitrogen and uric acid. There was a slight decrease in thiocyanate space and a temporary increase in liver glycogen. ACTH prevented normal weight gains and caused an increase in uric acid and total nitrogen excretion along with an increase in liver glycogen. Although there was no change in electrolyte excretion the sodium and potassium presumed to be released by tissue catabolism made it appear probable that there was retention of electrolytes by the kidneys. ACTH caused a small amount of adrenal hypertrophy. These data show that the hormones secreted by the adrenal of the bird produce effects similar to those in the mammal. The suggestion was made that the bird adrenal may be relatively autonomous and that it, therefore, functions at a relatively high level even in the absence of the anterior pituitary. It was also suggested that the ratio of adrenal steroids secreted, such as aldosterone, corticosterone, and dehydrocorticosterone, may vary according to the physiological needs of the animal.

WHEN an immature female rat is united in parabiosis with an ovariectomized littermate, the ovaries of the intact rat undergo hypertrophy (Kallas, 1930). This has been attributed to the hypersecretion of gonadotrophins by the pituitary of the castrated rat, the hormones of which pass directly via the blood to the intact partner where they stimulate the ovaries (Bunster and Meyer, 1938; Biddulph, Meyer and Gumbreck, 1940). It is believed that the gonadotrophin which increases in the ovariectomized female is largely follicle stimulating hormone (Greep, 1940; Biddulph and Meyer, 1946). Daily injections of small quantities of estrogen, or larger quantities of androgen, desoxycorticosterone acetate, or progresterone into the ovariectomized partner prevent the hypersecretion of the gonadotrophic hormones by the pituitary and the corresponding hypertrophy of the ovaries of the partner (Bunster and Meyer, 1933; Biddulph, Meyer and Gumbreck, 1940; Byrnes and Shipley, 1950).

PROLONGED estrogen treatment results in tumorigenesis of the anterior pituitary glands of rats and mice (Zondek, 1936; McEuen, Selye and Collip, 1936; Cramer and Horning, 1936). Such tumors do not arise until several months after the initiation of treatment and terminate in the death of the animal as a result of increased intracranial pressure (Nelson, 1941). Though the tumors have been studied extensively in the last two decades, the mechanism of induction has remained obscure. Several authors have proposed an association between the tumorigenic action and the effects of estrogen on pituitary secretory activity (Zondek, 1941; Gardner, 1953; and Furth, 1953).

The physiological effects of the oestrous hormone on the female rat have been studied quite exhaustively and the characteristie reactions produced are generally well known. However, the literature is rather obscure on the effect of oestrin on the growth and development of the ovaries of mature and immature animals. Allen and Doisy (1) reported that the follicular hormone had the ability to induce sexual maturity in 24-day-old female rats. The effect on the ovaries was not discussed. Golding and Ramirez (2) also studied the effect of ovarian follieular hormone on immature rats. Twenty rats, including males and females from two litters, were used. Five of these were kept as controls while 15 were treated as follows: The rats were injected twice daily with 2.5 R.U. of water soluble hormone beginning on the 12th to the 18th day of life and continuing for 24 to 36 days. The dosage was increased daily by 25 R.U. The vaginas of the rats opened in 9 to 14 days. The ovaries of the oestrin treated rats appeared grossly to be smaller than those of the controls but histologically they were quite similar. They remained infantile, no ovulation having occurred, and no corpora lutea being found in the ovaries. The body weights were not affected, but the weights of the thymus glands were decreased by half in the experimental animals. These workers also state that in some females, after the injections had been discontinued, regular oestrous cycles were established.

Treated with Gonadotrophin Thirty-two-day-old female rats, injected two days previously with gonadotrophin from pregnant mares' serum, were given barbiturate at different times during the afternoon to determine whether the ovulation that would occur the next day could be blocked. The results indicate that ovulation depends upon release of pituitary ovulating hormone during a"critical period" between 2 and 4 P.M.

Summary Normal and bursa-deficient chickens (obtained by surgery or 19-nortestosterone treatment) were immunized at 6 weeks with killed Brucella abortis. Antibody responses were assayed by a sensitive microagglutination test. Chickens with bursa weight > 1000 mg showed a rapid increase in mean log2 total antibody titer from 7 to a maximum of 21 at day 5 after immunization. Bursaless animals showed an increase from 3 to a maximum of 15 at day 7. The antibodies were chiefly mercaptoethanol-sensitive (IgM). By day 9 the total antibody titers in the bursaless and normal animals were almost the same—14 and 16. Bursaless chickens showed a very low ME-resistant (IgG) antibody titer (2) at day 9 when the normal chickens had IgG titers of 9. The IgG titers at day 9 of all animals, normal and bursa-deficient, were strongly correlated with the IgM titers at the time (day 2) of the first clearly detectable response. The log2 antibody titer on day 2 in turn was linearly related to log bursa weight from 6000 mg down to about 200 mg. When the bursa weight was below about 100 mg, the day 2 response was not different from that of bursaless animals. The observed subnormalities of bursa-deficient animals are consistent with a decrease in a largely bursa-dependent early immune response (and IgM antibody level) which determines the later, more severe impairment of IgG antibody synthesis.

Summary Thymectomy of chickens during the first 3 days of age does not consistently affect precipitin production to bovine serum albumin when challenged at 6 to 9 weeks of age. In some cases, thymectomized groups did not differ in mean peak titer from controls; in some cases the response was significantly lower; in one case the response was significantly higher. This variation was not evident for the time necessary to clear antigen from the circulation. Of intact and sham control birds 100% responded by producing precipitins, whereas 6% of the thymectomized birds did not give a detectable response. This frequency of negative responders was statistically significant. There was a tendency for groups with greater amounts of residual thymic tissue to give higher mean precipitin titers. However, the titers of birds with no residual thymus fell in a range very similar to that of the controls. The development of natural hemagglutinins was not affected by thymectomy. Splenectomy performed from 2 to 10 days of age significantly delayed the appearance of precipitins but did not affect the mean peak titer. Bursectomy at 1 to 2 days of age reduced the mean peak precipitin titers and the natural hemagglutinin titers drastically. Most birds did not give a detectable response.
