Influence of pregnancy on iron and copper exchange rates in women with normal body weight and women with obesity.

The number of obese pregnant women increases annually and reaches 20-30%. The metabolism of hormones and minerals changes in the presence of a large amount of adipose tissue in the body of a pregnant woman, which leads to a number of obstetric and perinatal problems. The aim of the work is to study and compare the influence of the gestational process on the indicators of iron and copper metabolism in the blood serum of women with normal body weight and women with obesity. In the blood serum of 125 women of reproductive age, the content of hemoglobin, iron, transferrin, ferritin, copper and ceruloplasmin was determined. The influence of pregnancy on the indicators of iron and copper metabolism in the blood serum of women was revealed. Pregnancy in women with normal body weight increases the content of transferrin and ceruloplasmin. Correlation of ceruloplasmin and ferritin content with body mass index of obese pregnant women was revealed. In pregnancy with concomitant obesity, hyperferritinemia is formed with a reduced content of hemoglobin and serum iron. Knowledge of the indicators of iron and copper metabolism is necessary to optimize the observation of pregnant women, effective prevention and prediction of obstetric and perinatal complications.

[Development of a method for evaluating the effectiveness of treatment of children with herpetic stomatitis.]

The high frequency of herpes infection in children determines the need to search for new diagnostic markers, evaluate treatment efficacy and predict relapse of the disease. The purpose of the work is to assess the possibility of using biochemical analysis of oral fluid to assess the effectiveness of treatment of children with acute herpetic stomatitis. In the oral fluid and blood plasma of 28 children of patients with acute herpetic stomatitis in the dynamics of the disease, the content of total protein, proteins of the acute phase of inflammation, as well as the concentrations of calcium, magnesium, copper and zinc was determined spectrophotometrically. Oral fluid and blood plasma of 45 practically healthy children were used as a control. In acute herpetic stomatitis, the content of C-reactive protein, orosomucoid, α1-antitrypsin, ceruloplasmin, prealbumin and microalbumin, as well as magnesium, calcium and zinc, increases in the oral fluid of children, but the level of total protein and transferrin decreases. In this blood plasma, the level of ceruloplasmin, orosomucoid, C-reactive protein, α1-antitrypsin is higher, and zinc is lower than in healthy children. The copper content in the oral fluid and blood plasma of children increases with moderate herpetic stomatitis, and significantly decreases with severe herpetic stomatitis. The degree of changes in the content of the proteins of acute phase of inflammation and indicators of mineral metabolism of the oral fluid and blood plasma of children with a herpetic infection of the oral cavity correlates with the severity of the disease. Highly significant correlations were revealed when comparing the concentrations of proteins of the acute phase of inflammation, electrolytes between the oral fluid and the blood plasma of children with acute herpetic stomatitis. After treatment of children with acute herpetic stomatitis, the content of minerals and proteins of the acute phase of inflammation in the oral fluid returned to normal only with a mild disease severity. A method has been developed for evaluating the effectiveness of treatment of children with acute herpetic stomatitis by determining the content of minerals in the oral fluid. The ratio of copper to calcium in the oral fluid of children more than 45 should be considered an indicator of effective treatment of children with herpetic stomatitis.

[Lacrimal and salivatory glycoproteins in ophthalmic herpes]. / Glikoproteiny slezy i rotovoi zhidkosti pri oftal'mogerpese.

AIM: to compare tear, saliva, and plasma levels of acute phase proteins (APPs) of inflammation in patients with herpes keratitis and to use the RESULTS in treatment evaluation. MATERIAL AND METHODS: APPs were measured in tears, oral fluid, and blood plasma from 22 adults and 34 children with ophthalmic herpes as well as 68 healthy controls using immunoturbidimetric and spectrophotometric methods of detection. RESULTS: High levels of C-reactive protein and orosomucoid, low levels of ceruloplasmin, α1-antitrypsin, and transferrin in tears from patients with herpes keratitis as well as abnormal tear, saliva, and plasma APPs levels at discharge are poor prognostic signs. They all indicate that corneal inflammation is still intense and that the treatment should not be ceased yet. Severity of APPs concentration changes in tear from patients with herpes keratitis correlates with the depth of corneal lesions, recurrence rate, and disease dynamics. CONCLUSION: Quantitative determination of acute phase proteins in tear and oral fluid is an early and sensitive inflammation test and may be also used for non-invasive monitoring and antiviral treatment evaluation. Oral fluid allows to extend the capabilities of non-invasive diagnostics of ophthalmic herpes.

[The investigation of alpha1-antitripsin, orozomukoid and ceruloplasmin in peripheral blood and oral fluid. Paradontitis is one of more risk factors of cardiovascular diseases].

This article presence the connection between paradontitis and cardiovascular diseases, and definition of the maintenance of acute phase proteins in an oral fluid at patients with acute myocardial infarction is obviously important for clinic. Results of own researches of change of the maintenance of three acute phase proteins: ceruloplasmin, alpha1-antitripsin and orosomucoid in an oral fluid and blood plasma at paradontitis and myocardial infarction allow to consider the paradontitis as one more risk factor of a cardiovascular pathology, except well-known hypertensions, smoking, a diabetes.

[The influence of acute alcohol intoxication on glycogen content in the liver and sceletal muscles].

The influence of ethanol on glycogen value in liver and skeletal muscle was investigated at rats and forensic cases. In 24 hours after ethanol intake glycogen value in rat's liver was low. By autopsy examinations liver glycogen value was low in cases as acute ethanol poisoning as coronary heard diseases with alcohol condition. No differences in muscle glycogen level were revealed. The results may be used in postmortem interval at differential diagnosis when blood alcohol is absence or traces.

[Diagnostic value of the determination of salivary acute-phase proteins in patients with myocardial infarction].

The salivary and plasma levels of acute phase proteins were determined in 59 patients with myocardial infarction (MI). In acute and subacute MI, the content of ceruloplasmin, orosomucoid, and alpha1-antitrypsin increased not only in the plasma, but also in the saliva. A noninvasive procedure was devised to diagnose the termination of an inflammatory process in the necrotic process in MI, which implies the determination of salivary ceruloplasmin, if the latter is less than 106 mg/l, inflammation completeness in the necrotic area is diagnosed. The procedure is simple, reliable, and usable in clinical laboratories.

[A new view on pathochemical mechanisms of prolonged peritoneal dialysis].

New data on etiology, pathogenesis, clinics, quantity estimation, treatment and complications of peritoneal dialysis are observed. The role of aquaporine, nitric oxide, NO-synthase, inflammation and sepsis markers (procalcitonine, C-reactive protein) in pathochemical mechanism of peritoneal dialysis is discussed.

[Experimental rationale for the use of enterosorbents in acute ethanol intoxication].

The experiment on 83 rats has provided a rationale for the use of enterosorbents in acute ethanol intoxication. Polysorb reduces the halflife of ethanol, recovers physical fitness in the animals with acute poisoning. The enterosorbents polysorb, litovit, and sapropel have been found to have a corrective effect on the level of the major plasma antioxidant ceruloplasmin in acute ethanol intoxication. Enterosorbents are an effective detoxifying agent in this condition. Examining the mechanisms of toxic action of ethanol allows the most expedient treatment policy to be substantiated in acute poisonings.

[Pathogenesis of ophthalmoherpes basing on the analysis of enzymes of the eye tissue and fluids].

To specify mechanisms of pathology development, we studied the activity of lysosomal glycosides in rabbit ocular tissues in experimental ophthalmoherpes. Rabbits with herpetic kepatitis show activation of beta-glucuronidase, beta-glycosidase, alpha-mannosidase in cornial epithelium and stroma, iris, aqueous humor of herpes-infected and contralateral eye. The activity of the above three glycosidases in the tears of children with herpetic keratitis was enhanced. If their activity does not regress after the treatment, ophthalmoherpes recurrence may be expected in the near future. For realization of its genetic program herpes simplex virus in infected cells activates synthesis of acid glycosidases this leading to degradation of cornial cell membranes, virus spread in the tissues and release of lysosomal enzymes into tear fluid.

[Effect of bacteriophage on the serum level of iron and copper in pregnant women with pyelonephritis].

Eighty-nine pregnant women, including 62 pregnant females with pyelonephritis, were examined. After bacteriophage treatment for pyelonephritis, there was an increase in the content of iron, a decrease in the level of soluble transferrin receptor without iron therapy, suggesting iron redistribution in pregnant woman. The blood levels of copper, ceruloplasmin, and transferrin in pregnant women with pyelonephritis point to antioxidative defense activation in both healthy pregnant women and pregnant females with pyelonephritis. The serum concentration of ceruloplasmin is of importance for prognosis and evaluation of ceruloplasmin in pregnant women. The higher content of ceruloplasmin in pregnancy is indicative of the involvement of protective mechanisms from autoaggression.

[Antioxidative defense parameters in acute and chronic cholecystitis].

A hundred and fifty-two patients cholelithiasis were examined. Among them, 69 and 83 patients were operated on for acute destructive and chronic cholecystitis, respectively. In destructive cholecystitis, there is a high lipid oxidation rate accompanied by the elevated levels of nonenzymatic antioxidant ceruloplasmin. The low activity of catalase and ceruloplasmin and the decreased content of ascorbic acid suggest the depletion of antioxidative defense in patients with cholelithiasis with significant liver disease. The magnitude of changes in the activity of antioxidative enzymes and the level of the nonenzymatic antioxidant ascorbic acid depend on the state of the liver.

[Analysis of tear enzymes in the diagnosis of obstructive jaundice associated with subhepatic cholestasis].

The activity of enzymes, such as alkaline phosphatase, gamma-glutamyl transpeptidase, and leicine aminopeptidase, was found to be increased in the serum and tear of 28 patients with obstructive jaundice. In malignant tumor-induced jaundice, the activity of the enzymes, the indicators of cholestasis, was higher than that in obstructive jaundice caused by extrahepatic bile duct calculi. A new method has been devised for noninvasive diagnosis of obstructive jaundice from tear enzyme immunoassay. The method is simple, reliable, and usable at a clinical laboratory.

[Use of tear enzyme assay to predict recurrent herpetic keratitis in children].

The purpose of the study was to develop a procedure for predicting a relapse of herpetic keratitis in children, by taking into account the results of tear biochemical analysis. The tears from 47 children with herpetic keratitis were examined for the levels of total protein, the concentration of acute-phase proteins, such as orosomucoid and C-reactive protein, the activities of transferases: gamma-glutamyltranspeptidase transferase, aspartate aminotransferase, and alanine aminotransferase, those of lysosomal glycosidases: alpha-mannosidase, beta-glycosidase, and beta-glucuronidase. Tear biochemical assay made it possible to evaluate the efficiency of treatment and to develop a procedure for predicting a recurrence of herpetic keratitis in children. Determination of the tear activity of the glycosidases may be used to predict recurrent herpetic keratitis in children.

[Prophylaxis of acute postoperative gastroduodenal ulcers at the patients with colorectal cancer].

Effective method for prophylaxis of acute postoperative gastric ulcers and erosions was developed. The core of this method is ozone therapy in preoperative period. Intensity of blood serum and erythrocytes chemiluminescence and ATPase activity of erythrocytes were studied at 86 patients with colorectal cancer before surgery and at 1st and 4th days of postoperative period. It was demonstrated that preoperative ozone therapy promoted normalization of free radical reactions and ATPase activity at postoperative period.

[Effect of sapropel mud on the parameters of oxidative stress and antioxidative defense in acute carbofos poisoning].

Sapropel was tested for its effect on the permeability of erythrocytic membranes and on the erythrocytic and serum levels of ceruloplasmin, malonic dialdehyde, and dienic conjugates in rats after acute poisoning by carbofos, a malathion insecticide. The increased processes of free radical oxidation during carbofos poisoning were suggested by the higher rates of chemiluminescence of erythrocytes and peripheral blood serum. No significant changes in the parameters of blood oxidative stress in the carbofos-poisoned animals during therapeutic-and-prophylactic use of sapropel indicate that the latter has antioxidative properties. Application of sapropel to normal animals exerted no effect of the studied parameters of oxidative stress. In acute carbofos poisoining, oral sapropel produced a pronounced antioxidative effect, which opens up new vistas for its practical application.

[Biochemical analysis of the vitreous body of the eye in post-mortem diagnosis of diabetic coma].

The biochemical test of the vitreous body (VB) may be used in post-mortem diagnosis of diabetes mellitus and diabetic coma. Concentrations of glucose, lactate, keton bodies in the VB of the eye do not depend on duration of post-mortem period. Methods of diagnosis of hyperglycemic, hypoglycemic and ketoacidotic comas in the postmortem period are proposed. VB glucose over 17 mmol/l is a specific marker indicating death due to diabetic coma with hyperglycemia. Blood lactate under 16 mmol/l and glucose absence in the VB specifically mark death of hypoglycemic coma. In death of diabetic coma with ketoacidosis, a sharp rise in the level of VB ketonic bodies was observed.

[The activity of adenosinetriphosphatase of erythrocytes in peripheral blood of patients with colorectal cancer].

We studied the activity of whole ATPase, Mg2+ -ATPase and Na+, K+ -ATPase of peripheral blood erythrocytes in 68 patients with colorectal cancer before surgery and immediately after it and found such activity to be reduced. The low activity of Na+, K+ -ATPase of peripheral blood erythrocyte was shown as possible for use in prognosticating acute postoperative erosive-ulcerous lesions of the gastric tunic. Ozone therapy, if undertaken preoperatively, restores the ATPase activity.

[Chemiluminescence analysis of biological fluids in patients with diabetes mellitus]. / Khemiliuminestsentnyi analiz biologicheskikh zhidkostei bol'nykh sakharnym diabetom.

Chemiluminescence analysis (CA) was made for different biological fluids in 50 patients with diabetes mellitus (DM). Intensified chemiluminescence of erythrocytes, blood serum, urine and tear is indicative of an enhanced free-radical oxidation in diabetes mellitus. CA of biological fluids made in DM patients reflects a disease severity. The study results confirm the need to add antioxidants to the treatment course of DM patients.

[A new bone/blood index in the study of labelled citrate metabolism in rat bones in fracture, deafferentation, rickets, and caries]. / Novyi koéffitsient kost'/krov' v izuchenii metabolizma mechenogo tsitrata v kostiakh krys pri perelome, deafferentatsii, rakhite i kariese.

A new bone/blood index has been developed which is calculated by dividing % of radionuclide inclusion in the bones by % of the inclusion in the serum. Graphic image of the index changes with time is significantly more demonstrative than digital tables and allows one not only easily measure distribution of the labelled compound between fractions diluted in the blood and sorbed on the bone but also specify a major direction of their transport between blood and bone. The index confirms the presence of biphasic primary fast but weak physical adsorption and secondary slow and strong chemisorption. This was established by the study of time course of the labelled citrate in intact rats of different age as well as in fracture and bone innervation defect, in rickets and dental caries. The proposed index can be applied in investigation of various diseases.

[Activity of the antioxidant enzymes of erythrocytes in herpetic keratitis]. / Aktivnost' antioksidantnykh fermentov éritrotsitov pri gerpeticheskom keratite.

Free-radical oxidations get activated, the activity of catalase slows down and the activity of superoxiddismutase increases in peripheral blood erythrocytes of patients with herpetic keratitis, which is indicative of a changing antioxidant protection in late stages of herpetic infection. The results reveal new chains in the evolution of ophthalmic herpes and confirm the feasibility of adding antioxidants to the complex therapy of patients with herpetic keratitis.
