A total of 130 patients with mandibular fractures of various sites were observed. One group of these patients were administered routine treatment, the other group patients were administered drugs improving the local circulation along with the physical modalities. Local circulation normalized two times sooner in this latter group, which fact accelerated the reparative processes and the treatment resulted in a sooner coalition of bone fragments and recovery of the working ability and functional parameters. 相似文献

The authors claim that combined use of a special therapeutic paste and low-frequency ultrasound for therapy of alveolitis help reduce the number of visits to a dentist and shorten the treatment duration. Fifteen patients were treated by this method. They had to visit the dentist two times less and the number of invalidity days was less by 2.2 days, on an average. 相似文献

Cultures of islets cells were obtained from the cadaveric pancreas of 16–25-week human fetuses. During culture two waves of mitotic activity were observed. An increase in the insulin concentration in the culture medium took place after a wave of mitotic activity.Department of Artificial Organs and Assisted Circulation, Laboratory of Pathomorphology, Scientific-Research Institute of Transplantation and Artificial Organs, Ministry of Health of the USSR.

By electrophoresis followed by colorimetric study of the stained gels an increased content of growth hormone and prolactin was found in the pituitary of rats during the development of alloxan diabetes. The STH and prolactin levels 4–5 days after injection of alloxan were higher by 45–58 and 38–43% respectively than in intact animals. Experiments on primary cell cultures using [14C]-L-leucine as labeled precursor revealed increased secretory activity of the somatotrophs and lactotrophs of rats with alloxan diabetes.Laboratory of Biological Standardization of Hormones, Institute of Experimental Endocrinology and Hormone Chemistry, Academy of Medical Sciences of the USSR, Moscow.

Characterization of foreign bodies and their localization in the digestive tract in 404 patients is given. Surgical methods of treatment of such patients are described. Endoscopy was used for examination and treatment. The adequate anesthesia is thought by the authors to be necessary for a successful endoscopic removal of the foreign bodies. The indications for general anesthesia are enumerated. The endoscopic removal of the foreign bodies during surgical interventions are indicated in patients with the perforation of the esophagus by a foreign body. 相似文献

1. | Judging by the intensity of the synthesis of DNA, the total population of hypophyseal cells of rats of the neonatal and nursing periods is more sensitive to the inhibitory influence of corticosteroids than cells of the hypophyses of animals of the prepubertal period and adults. |
2. | The hypophyseal cells of rats of the early postnatal period react to corticosteroids with attenuation of the synthesis of intracellular proteins, while cells of animals of the prepubertal period and adults do not manifest this reaction. |
3. | The marked inhibitory effect of the corticosteroids on hypophyseal cells of rats of the neonatal period is specific, since estradiol and testosterone do not alter the synthesis of DNA and total proteins, while progesterone exerts an insignificant inhibitory influence which is much weaker than the effects of corticosteroid. |
4. | The inhibitory influence of dexamethasone on the synthesis of DNA in the hypophyseal cells of rats of the neonatal period is detected only with prolonged (1–3-day) incubation, whereas inhibitory influence of this glucocorticoid on the synthesis of total proteins is found after as little as 2 h of incubation and is maintained during chronic (3-day) exposure. |
