Problems in evaluating chronic toxicity of contraceptive steroids in dogs.

The long-term effects of oral contraceptive steroids including a combination of norethindrone and ethynylestradiol, a sequential regimen of dimethisterone and ethynylestradiol, and daily administration of megestrol acetate were studied in female beagle dogs at dose levels of 1, 10, or 25 times the projected human dose levels. The major findings included cystic endometrial hyperplasia and pyometra requiring hysterectomies and alopecia for the norethindrone-ethynylestradiol and dimethisterone-ethynylestradiol treated dogs. These groups did not have accentuated mammary development or treatment-related hyperplastic or neoplastic changes. For dogs given dimethisterone-ethynylestradiol, numerous acne-like lesions occurred in the skin of the mammary areas. Dogs given the higher dose levels of megestrol acetate had marked mammary stimulation, hyperplastic and neoplastic changes in the mammary glands, and clinical and pathologic changes typical of diabetes mellitus. Mammary changes of nodular hyperplasia, benign mixed tumor, and adenocarcinoma appeared as distinct entities although constant and intense mammary stimulation may be a common denominator. Such mammary changes have not been found in long-term studies in monkeys or rats with megestrol acetate, and the relevance of the canine mammary changes to projecting potential tumorigenesis in women is questioned.

Benign breast tumor and estrogenic hormones: a population-based retrospective study.

Histories of the usage of oral contraceptives and other estrogens were obtained from 320 women 20-49 years of age who had pathologically confirmed diagnoses of benign breast disease made at Washington County Hospital in Hagerstown, Maryland, during the period 1968 through 1972. Similar histories were obtained from 320 controls matched for race, sex, age, residence in county, and willingness to participate in a health survey. No association could be found between oral contraceptive usage and benign breast tumor. The use of other estrogens, notably diethylstilbestrol, was significantly related to the presence of benign breast disease.

Benign liver cell adenoma associated with use of oral contraceptive agents.

A benign hepatic adenoma in a young woman taking oral contraceptives for 7 years is reported. The diagnosis must be suspected in any young woman taking oral contraceptive agents who develop signs and symptoms of acute cholecystitis with hepatomegaly or mass, or when signs and symptoms of non-traumatic intraabdominal hemorrhage are present. Rupture of the tumor is a life-threatening complication. Treatment should be either hepatic lobectomy or wide local resection.

[Demonstration of a critical period of ovarian activity in the control of early receptivity induced by estrogen in the female rat with 4-day cycles].

A significant decrease in early receptivity during the night from dioestrus II to prooestrus was observed in estrogen-treated 4-day cyclic rats following bilateral ovariectomy on dioestrus II at 4-5 p.m. Early receptivity appeared then to be dependent on the presence of ovary at this stage of the cycle. The mechanism whereby the adrenals may compensate for the ovaries when removed on dioestrus I, at 10-11 a. m. (Roos et al. 1973), was not observed in the present experimental conditions.

Enzymatic responses of transplanted tumour cells towards estrogen, progesterone and testosterone.

The influence of estrogen, progesterone and testosterone on the activities of alkaline and acid phosphatases, adenosine triphosphatase and succinate dehydrogenase were determined by cytochemical methods in sarcoma 180 and Ehrlich's carcinoma cells transplanted in male and female Swiss mice. The results revealed differential effects of the sex hormones on different enzymes which seemed to depend on the type of tumour cell studied and the sex of the host mice.

Interaction of perphenazine and an ergoline derivative on oestrogen-induced adenohypophyseal growth.

Male and female rats were injected twice a week for three weeks with doses of 1 mg oestradiol benzoate (OE), were given perphenazine (P, 2 mg/rat/day) or the ergoline derivative D-6-methyl-8-ergoline-(I)-yl acetic acid amide (Deprenon SPOFA, D, 200 microng/rat/day) in their food or were treated with various combinations of all three factors. OE-induced adenohypophyseal growth was inhibited by D, but the inhibitory effect of D was completely suppressed by P. D also inhibited the OE-induced increase in the thyroxine-binding capacity of the adenohypophyseal proteins, but this inhibition was not suppressed by the simultaneous administration of P. The administration of OE was followed by elevation of the serum ceruloplasmin level, which was not inhibited by P or D, either alone or combined. Ovarian weight rose markedly after D and the increase was inhibited by the simultaneous administration of either OE or P.

Investigation of the serum level of pregnancy-associated alpha2-globulin during contraceptive treatment by means of radial immunodiffusion method.

The serum level of pregnancy-associated alpha2-globulin was studied in 70 healthy women taking three different types of oral contraceptives [40 Bisecurin: containing 1.0 mg of Ethynodiol diaceticum +0.05 mg Ethynilestradiol; 20 Infecundin: containing 2.5 mg of Norethynodrel +0.1 mg of Mestranol; 10 Cervicundin: containing of 0.5 mg Ethynodiol diaceticum]. Elevated amounts of serum level of pregnancy associated alpha2-globulin could be detected in 37 of the 40 women taking Bisecurin and in all 20 taking Infecundin. Cervicundin however, failed to induce any change in the serum protein pattern of the 10 subjects studied. Serum levels of pregnancy-associated alpha2-globulin were higher in the Infecundin-taking (53 mg %), than in the Bisecurin-taking group (29 mg %). This shows the oestrogen dependency of the pregnancy-associated alpha2-globulin and points to a possible implication of this globulin in the immunosuppressive processes.

[Liver function tests under the influence of sequential treatment using ethinyl estradiol-norethisterone acetate and ethinyl estradiol-chlormadinone acetate].

30 young healthy women were investigated during the first therapy cycle with ethinyl-estradiol-norethisterone acetate and ethinyl-estradiol-chlormadinone acetate as a sequential regime. The following laboratory data were achieved by each of the investigated group of young women: serum aminotransferase (GOT and GPT), serum alkaline phosphatase and alpha-amylase-activity in serum, serum proteins, serum cholesterol, serum bilirubin, serum ZST, serum TTT and the indocyaningreen-clearance of the liver. The serum protein pattern was determined by the paper electrophoretic method. A significant decrease of the aminotransferase GPT was viable during the sequential therapy with ethinyl-estradiol and norethisterone acetate. This viable decrease of the GPT was induced through the application of norethisterone acetate to estrogen. The alkaline phosphatase was significant lightly lower and the beta-globuline lightly elevated at the end of the therapy cycle. The sequential therapy with ethinyl-estradiol and chlormadinone acetate induced only a significant increase of the ZST in serum.

[Effect of oral contraceptives on the psyche and on sexuality].

The problem of whether or not oral contraceptives affect the psychic function of the female is still controversal. The purpose of the present investigation was to study the occurrence of psychic and sexual effects in women taking either Ovosiston (mestranol 0,08 mg + chlormadinone acetate 2, 0 mg) or Non-Ovlon (ethinylestradiol 0,05 mg + norethisterone acetate 1,0 mg). 186 somatically healthy women were subject to two interviews, immediately before the start of therapy and six months after it. Most of the patients recorded distinctly alterations of their mood, their initiative, their elemental desires such as appetite, sleep, need of warmth, and their sexual behaviour. 73 of them noted a change in their emotional pattern, which was positive in 34 and negative in 39 cases. 99 women reported changes in their elemental desires. 136 patients exhibited alterations of their sexual behaviour, which were assessed as an improvement or impairment in 108 and 28 cases, respectively. There is a statistically significant correlation between the impairment of sexual function and the incidence of other untoward side effects. On the other hand, negative suggestion by poor experience of other women on by the influence of mass media seems to play a minor role in producing changes of sexual behaviour. There is, however, a clearcut relationship between negative suggestion and the incidence of unfavourable emotional alterations. The findings are discussed with reference to their clinical significance.
