The occurrence and mean content of androgen receptors in the cytosolic fraction of prostatic adenocarcinoma depend on the
age of patients, stage of tumor anaplasia, tumor differentiation, type of therapy, and the concentration of androgen receptors.

The levels of estradiol and progesterone receptors in the myometrium of 19 patients subjected to planned cesarean section
were studied. Nine of these patients had competent cicatrices on the uterus, which was confirmed by preoperative studies and
during the operation. For comparison, the myometrium of patients at the same terms of gestation subjected to planned abdorninal
delivery without history of cesarean section was examined. No significant differences were revealed in estradiol and progesterone
reception in the myometria of parturients with and without competent cicatrices on the uterus.

Intense expression of prolactin receptors in cholangiocyte nuclei, nuclear membranes, and cytoplasm was demonstrated by the
indirect immunoperoxidase method in intact and gonadectomied male and female rats after ligation of the common bile duct.
The intensity of staining increased during cholangiocyte proliferative response to the intervention and, in contrast to hepatocytes,
did not depend on animal sex and the presence of the gonads.

Radioligand assay demonstrated that in patients with non-small-cell lung cancer, expression of epidermal growth factor receptors
in the tumor is higher than in non-tumor tissue. Expression of epidermal growth factor receptors in tumor and non-tumor lung
tissue does not correlate with the stage and metastasizing of the disease and tumor histology. It is also shown that expression
of epidermal growth factor receptors in tumor and non-tumor tissue is associated with lower survival rate.

The content of receptors for the epidermal growth factor and estrogens is studied in primary human bone tumors: osteogenic
sarcoma, chondrosarcoma, malignant fibrous histiocytoma, and giant cell tumor. In all of these tumors, radioligand analysis
reveals receptors for epidermal growth factor in the membrane fraction and receptors for estrogens in the cytosolic fraction
without any statistical differences in the mean receptor content. The vast majority of osteogenic sarcomas, chondrosarcomas
of the 2nd–3rd degree of anaplasia, and one third of giant cell tumors are characterized as growth factor receptor-positive
and estrogen receptor-negative, which probably reflects the common tendency of receptor-positive malignant tumors towards
rapid growth.

Prolactin injected to male guinea pigs for 7 days considerably enhanced binding of125I-prolactin by adrenal cortex microsomes. Scatchard analysis showed that this rise is due to an increase in the receptor binding
capacity but not in their affinity.

Cell localization of mucin type receptors in low-differentiated human colon adenocarcinoma was studied. Several types of receptor
localization were identified. It was shown that lectin CGL most intensively binds to intracellular membranes, cytoplasm, and
secrete of mucin-producing tumor cells.

The pancreas in endotoxin shock is characterized by the hypoperfusion, prolonged cycle of acinar cell secretion, and activation
of their lysosomal system. The rearrangements in the exocrine part of the gland involve the production of a myocardial depressant
factor exerting a negative inotropic effect on the heart. Myocardial dysfunction is aggravated by myofibrillar contractures,
myocytolysis, glycogenolysis, and circulatory disorders.

Androgen receptors in the liver of pubertal male rats are identified by an indirect immunoperoxidase method. Hepatocyte nuclei
predominate among positively stained structures. The intensity of staining varies from hepatocyte to hepatocyte and does not
depend on its position in the liver lobule.

Incorporation of cortisol-3H and the dynamics of its accumulation in the tissues and media of the eye (sclera, ciliary body, cornea, iris, capsule of the lens, aqueous humor, vitreous body) were investigated. The intensity of incorporation of cortisol into the tissues and media of the eye and also the rate of its elimination from them were shown to differ. The sclera, cornea, ciliary body, and the capsule of the lens were shown to be target tissues for cortisol.Moscow Helmholtz Scientific-Research Institute of Eye Diseases.

Four types of steroid receptors were assayed in 1715 tumors of various localization and in 101 normal tissue samples from
the mammary gland, uterus, and endometrium; tissuespecific distribution of steroid receptors was demonstrated. Expression
of steroid hormones (especially estrogen receptors) is enhanced in proliferating compared with resting tissues and in hormone-sensitive
tumors compared with adjacent normal tissue. It is assumed that hormone sensitivity of the tumor reflects hormone sensitivity
of parental organ.

The effect of intraventricular administration of opioid peptides on the frequency and severity of ventricular arrhythmias
is studied after intravenous injection of epinephrine. It is found that the selective μ-agonist DAGO and the nonselective
σ-agonist DADLE decrease the frequency and severity of arrhythmias. On the other hand, the selective σ-agonist DSLET and the
κ-agonist dinorphine A 1–13 potentiate adrenal arrhythmias.

In patients with lung cancer and malignant tumors of the head and neck, erythrocyte hyperpolarization associated with the
opening of Ca2+-activated potassium channels develops with lower rate and amplitude compared with that in healthy donors. Restoration of
normal membrane potential is Ca2+-ATPase-dependent. The rate of restoration is significantly higher in patients with tumors. Two groups with different hyperpolarization
response and their dynamics during chemotherapy were identified in patients with lung cancer. Ca2+-induced erythrocyte hyperpolarization and its dynamics during cytostatic therapy depend on tumor localization and histological
type.

Intravenous injection of the selective cannabinoid receptor agonist HU-210 in doses of 0.05 and 0.25 mg/kg increased heart
resistance to arrhythmogenic effects of epinephrine, while intracerebroventricular infusion of this substance had no effect
on the incidence of epinephrine-induced arrhythmia. The selective antagonist of type I cannabinoid receptors SR141716A in
a dose of 3 mg/kg and ganglion blocker hexamethonium in a dose of 10 mg/kg did not modify the antiarrhythmic effect of HU-210.
This effect of HU-210 is probably related to activation of type II peripheral cannabinoid receptors.

The role of auto-paracrine regulation of cell proliferation in breast cancer is analyzed. Experimental data indicate that
the epidermal growth factor receptor is the key transmitter of mitogenic signals from the polypeptide growth factors and participates
in the formation of sensitivity and/or resistance of breast cancer cells to steroid hormones. Data of representative clinical
studies indicate that the expression of the epidermal growth factor receptor is prognostically unfavorable in breast cancer.
Screening of patients with breast tumors for this receptor will detect the high-risk group at early stages of the disease.
A scheme of the screening is proposed.

It is demonstrated that benzodiazepine binding sites on human peripheral blood lymphocytes are the peripheral type receptors.
The binding sites for the selective agonist3H-Ro 5-4864, but not for the antagonist3H-PK 11195, are completely inactivated by freezing-thawing of lymphocytes. The binding of3H-Ro 5-4864 to intact lymphocytes is activated by GABA and (+)baclofen. It is shown that the selective ligands Ro 5-4864 and
PK 11195 bind to different subtypes of benzodiazepine receptors on human peripheral blood lymphocytes.

In patients with untreated tumors (lung cancer, head and neck tumors, stomach and colon cancer), erythrocyte membranes are
characterized by a decreased content of total lipids together with increased percentage of cholesterol and lysophosphatidylcholine
in comparison with healthy individuals. The observed shifts depend on tumor location.

Immunogenesis was appreciably stimulated in CBA mice injected the μ-opioid receptor agonist DAGO. This stimulation was prevented
by transecting the pituitary peduncle. Immunoactivation induced by opioid peptide was due to interaction with the dopaminergic
system, because the effect is canceled by preliminary haloperidol blocking of D2-postsynaptic receptors.
