[A method for the re-embedding of tissues from paraffin blocks into epoxy resins for the study of stained semithin sections by electron microscopy]. / Metod perezalivki tkanei iz parafinovykh blokov v époksidnye smoly dlia issledovaniia okrashennykh polutonkikh srezov metodom élektronnoi mikroskopii.

The proposed method or re-embedding tissue specimens from paraffin in epoxy resins (epon, araldite, etc.) permits study of the same material at histo-, cyto-, and ultrastructural levels by modern morphological methods and thus detecting a number of additional morphological signs important for thanatogenesis. The proposed method provides objective results and improves the quality of forensic medical studies in general.

[The ultrastructural indices of the morphofunctional state of the heart in acute and chronic alcoholic intoxication]. / Ul'trastrukturnye pokazateli morfofunktsional'nogo sostoianiia serdtsa pri ostrykh i khronicheskikh alkogol'nykh intoksikatsiiakh.

Morphofunctional myocardial characteristics in subjects who died of acute and chronic alcoholic intoxication were studied at ultrastructural level. The resulting new data enhance the level of diagnosis concerning the cause of death, the grounds of thanatogenesis. Possibilities for using the results of investigation in scientific and practical work are shown.

The study was performed on 20 guinea-pigs. The animals were injured by alternating current at 380 and 220 V. The developing destructive alterations were characterized by histological, histochemical and electron-microscopic techniques, and a complex of electric markers was established. A dependence of morphological changes on the voltage values was demonstrated. The complex of alterations found may be employed for the differentiation of electric markers from mechanical or thermal injuries.

[Ultrastructural morphology of acute alcoholic intoxication]. / Ul'trastrukturnaia morfologiia ostrogo otravleniia alkogolem.

Histologic and electron-microscopic examination of the liver, heart, kidneys, lungs of 32 individuals who died from acute alcoholic intoxication (alcoholemia from 2,9 to 7,2 0/00) and 16 people who died suddenly from a trauma being in the state of a severe alcoholic intoxication. Material was taken for the examination within 3 hours after death. The ultrastructural alterations detected in the organs reflect a deep metabolic disturbances resulting from an acute or chronic alcoholic intoxication. The relation of morphological changes with an age and an alcohol abuse duration is discussed.

[Selective Lugol's solution staining in the diagnosis of carcinomatous and inflammatory lesions of the esophagus]. / Selektivnoe okrashivanie rastvorom Liugolia v diagnostike kantseromatoznykh i vospalitel'nykh porazhenii pishchevoda.

The selective character of staining the intact mucosa with Lugol's solution is dependent on the glycogen content in the superficial epithelial layer of the oesophagus. The inflammatory or carcinomatous epithelium being not stained is accounted for by changes in the glycogen content in the oesophageal epithelium which makes the staining method useful for diagnozing carcinomatous and inflammatory diseases of the oesophagus.

[Experience in the use of IUDs and the risk of inflammatory genital diseases in inserting them in the early period after birth]. / Opit v prilaganeto na VMS i riskut ot vuzpalitelni zaboliavaniia na genitaliite pri postavianeto im v rannite srokove sled razhdaneto.

PIP: To evaluate a possible risk of development of inflammatory diseases of the genital organs in IUD users, 410 women in whom IUD was inserted on day 5 after normal delivery were followed up for 3 years. The follow-up included gynecologic, colposcopic, and bacteriologic examinations. IUD insertion shortly after childbirth did not affect the course of the puerperal period. Within the 1st 3-6 months, 13% of the women showed expulsion of the IUD and had to undergo the reinsertion of the device. The IUD did not increase the incidence of vaginal discharge (6%, compared with 6.3% reported in the literature). Bacteriologic examination of the vaginal and cervical content showed prevalence of cocci and gram-positive bacteria identical to those in women who did not use the IUD. Histological examination of the endometrium in 65 women indicated chronic endometritis in 4 and foci of the perivascular and periglandular round cell and leukocytic infiltration indicative of a local nonspecific immune response to the foreign body in 26. Among these 65 women, 15 showed proliferative phase of the endometrium, 24 showed early secretory phase and 26 showed secretory phase. The state of the endometrium corresponded to the phase of the menstrual cycle in 41 of 65 women. It was concluded that the incidence of complications in women subjected to IUD insertion after childbirth did not exceed that of the general population.^ieng

[Hyperplastic processes in cardiac muscle mitochondria exposed to toxic doses of adrenaline]. / Giperplasticheskie protsessy v mitokhondriiakh myshechnykh kletok serdtsa posle vozdeistviia toksicheskikh doz adrenalina

Experiments were conducted on albino rats; a study was made of hyperplastic processes in the mitochondria of the myocytes of the heart with the action of toxic adrenaline doses. A solution of adrenaline chloride was injested intramuscularly (3 mg/kg). Three types of mitochondria were revealed in electron microscopic study. Mitochondria of the first type were of the size and structure characteristic of the muscle cells of the myocardium. Mitochondria of the second type had a very dense, finegrained matrix and a great number of cristae per unit of the area. Mitochondria of the third type had two "sections" under the common external membrane, differing from one another by the matrix density, distribution and number of cristae. It is supposed that the ultrastructural peculiarities of each of the types reflected their functional condition.
