Complications after different surgical methods of setting polypropylene suburethral meshes in women with stress urinary incontinence
The aim: to determine the complication's rate, based on a seven-year experience, after the stress urinary incontinence correction in women with different methods of setting suburethral polypropylene meshes. Material and Methods. The analysis of seven years of experience of surgical correction with different methods of setting suburethral meshes in 1260 women with stress urinary incontinence; obturator fixation the mesh inside-outside and outside-inside: supra-pubic fixation the mesh; non-trocar fixation the mesh type mini-sling was carried out. Results. The greatest frequency of complications were identified in the first two years of implementation the setting of suburethral meshes, after that the complication's rate decreased progressively and it was in the range 7-8% the last three years. The frequency of early operative complications at a different setting of suburethral meshes had no statistically significant differences, but there were more the statistically significant intraoperative and mesh-associated complications at suprapubic fixation. Conclusion. The study confirms that the installation of suburethral meshes by the method of suprapubic fixation of mesh is associated with a higher incidence of complications and should be performed only in the target group of patients who are not suitable for surgical correction in safer ways.</p
Content of heavy metals in the hair
The aim of our investigation was to determine of HM content in the hair of people and animals. Two of the main
essential elements-Zn and Cu and two of the supertoxical heavy metals- Pb and Cd were chosen. The investigations were
conducted in Russian Federation and Belarus Republic in 2001-2002. About 500 hair samples of people, dogs, cats, cattle,
horses, yaks, pigs, sheep goats and rabbits were studied by the stripping voltammetric analysis (SVA) method with TA- 2
analyzer to determine Zn, Cu, Pb and Cd concentrations. The hair samples were prepared according to the methods developed
in Tomsk University (Russia) and improved by the authors. The essence of the methods is the multiconsecutive burning of hair
samples to ashes and boiling them in concentrated acids to dissolve chemical combinations and transform their metals into ion
forms.
The zinc concentration was the highest in all hair samples (58.65 ... 195.15 mg/kg). The copper content was several times less
(5.49 ... 22.63 mg/kg). Lead and cadmium were detected in relatively low amounts (0.32 ... 2.42 mg/kg and 0.04 ... 0.92 mg/kg respectively). The highest Pb and Cd levels were detected in cats and people hair
Heavy metals influence on ascorbic acid level
It is well known that heavy metals (HM) are extremely dangerous pollutants influencing to metabolism in animals'
organisms. The vitamin C is one of the most important metabolites taking part in many biochemical processes.
We studied the influence of main essential HM-Zn and Cu as well as the based supertoxical elements - Cd and Pd on ascorbic
acid level in serum.
The studies were carried out in Tulinskoe farm of Novosibirsk region. The objects of investigations were piglets (2Â month after
weaning) and 6-month pigs of Early Ripe Meat breed. The levels of HM in bristle were found by stripping voltammetric
analysis using the TA-2 analyzer. Vitamin C content was determined by I.P. Kondrakhin (1985) method using 2,2-dipyridyl.
The significant negative correlations between Pb, Cd content and vitamin C
(, ) in 6-month pigs were
determined. The tendencies of negative correlation between all HM levels in hair and ascorbic acid level in plasma of piglets
were revealed.
Thus, the obtained correlations let us to suppose that all studied HM influence on 1-gulono-gamma-lactone oxidase and other
vitamin C metabolism enzymes activity
Cs-137 and Sr-90 level in diary products
About 70% of radioactive substances fell on the territory of the Byelorussia Republic after the Chernobyl Atom
Power Station Disaster. Cs-137 and Sr-90 accumulation dynamics was studied in milk of the cows from the highest polluted
Braginsky area. 408 milk samples of Black and White cows were investigated. In 1995 average Cs-137 and Sr-90 levels were
61.00 and 3.73 Bk/dm respectively. Cs-137 and Sr-90 levels exceeded Byelorussia Republic upperlimits RDU – 96 in 10 and
50% of milk samples respectively. After 5 years (by 2000) Cs-137 and Sr-90 levels had become almost 3 and 2 times less
(21.70 Bk/dm and 1.72 Bk/dm respectively). Cs-137 and Sr-90 levels exceeded RDU – 96 in 1.5 and 5.5% of milk samples
respectively. In the same periods Cs-137 and Sr-90 levels were 7 and 2 times higher than the similar indexes in the relatively
clean Novosibirsk area. Thus, radioactive element levels in milk of Black and White cows of the Byelorussia Republic
decreased significantly for the past years
Characterizing physiological status in three breeds of bulls reared under ecological and climate conditions of the Altai region
Ecological and climatic factors have an impact on the health, productivity and reproduction of the cattle. The goal of this work is the study of physiological status of servicing bulls reared under ecological and climate conditions of the Altai region, by defining the differences between Red-Steppe, Simmental and Black-and-White breeds in spermatogenic, hormonal, biochemical and hematological parameters. Samples of peripheral blood and ejaculates were taken from 48 grown-up servicing bulls (average age 5.6±0.3 years) in autumn period. It was established that Red-Steppe bulls have higher concentrations of nonorganic phosphorus, leucocytes, erythrocytes, hemoglobin, hematocrit and erythrocyte sedimentation rate in comparison with animals of Simmental breed, and the hemoglobin concentration and hematocrit are also higher in comparison with Black-and-White breed. It was noted that bulls of Black-and-White breed have a higher level of cortisol in comparison with the other breeds. The lowest level of serum urea and total protein and increased serum activity of creatine kinase and γ-glutamyl transferase, as well as the heaviest body weight were observed in Simmental breed bulls. The differences between breeds in a wide spectrum of physiological measures reflect not only genetically determined peculiarities of homeostatic mechanism, but also may reflect different ability to adapt to local ecological and climate conditions of the Altai region. Spermatogenic, biochemical and hematological measures in bull sires reared in the Altai region were similar to those in bulls bred in other Russian regions and some other countries. The measures reported could serve as reference values and therefore represent ‘normal’ values of physiological status for these bull sires reared in this ecological and climatic zone, but could be utilized in further studies for comprehensive monitoring of cattle breeding stock in other ecological and climatic zones of the Siberian region of Russia
