The assessment of pathological changes in cerebral blood flow in hypertensive rats with stress-induced intracranial hemorrhage using Doppler OCT: Particularities of arterial and venous alterations/Die Beurteilung von pathologischen Veränderungen der Hirndurchblutung bei hypertensiven Ratten mit Stress-induzierten intrakraniellen Blutungen mittels Doppler-OCT: Besonderheiten von arteriellen und venösen Veränderungen

Abstract<p>Hemorrhagic insult is a major source of morbidity and mortality in both adults and newborn babies in the developed countries. The mechanisms underlying the non-traumatic rupture of cerebral vessels are not fully clear, but there is strong evidence that stress, which is associated with an increase in arterial blood pressure, plays a crucial role in the development of acute intracranial hemorrhage (ICH), and alterations in cerebral blood flow (CBF) may contribute to the pathogenesis of ICH. The problem is that there are no effective diagnostic methods that allow for a prognosis of risk to be made for the development of ICH. Therefore, quantitative assessment of CBF may significantly advance the understanding of the nature of ICH. The aim of this study was to determine the particularities of alterations in arterial and venous cerebral circulation in hypertensive rats at different stages of stress-related development of ICH using three-dimensional Doppler optical coherence tomography (DOCT).</p><p>Experiments were performed in mongrel adult rats. To induce ICH, hypertensive rats underwent stress (effect of severe sound, 120 dB during 2 h). To induce the renal hypertension (two kidneys, one clip) the rats were clipped at the left renal artery with a silver clip. Seven weeks after clipping, the hypertensive rats were used in the experiment. The monitoring of CBF was performed in anesthetized rats with fixed heads using a commercially available swept source OCT system (OCS1300SS; Thorlabs) in the masked period of ICH (4 h after stress) and during ICH (24 h after stress).</p><p>It could be shown that in stressed rats, compared with non-stressed animals, the latent stage of stress-induced ICH (4 h after stress-off) is characterized by an increase in diameter of the superior sagittal vein with decrease in speed of the blood flow in the venous network, whereas no changes in the CBF in the arterial tree were found in this period. These facts suggest that the masked period of ICH is accompanied by decreasing venous outflow and the development of venous insufficiency. The incidence of ICH, 24 h after stress, is associated with progression of pathological alterations in cerebral venous circulation. All hypertensive rats with ICH demonstrated a greater increase in the diameter of the superior sagittal vein than stressed rats at the latent stage of ICH (in 2.5-fold,</p><p>In summary, using DOCT we have shown that the latent stage of stress-induced ICH is characterized by a decrease in venous outflow. The incidence of ICH is associated with the progression of pathological alterations in cerebral venous circulation that is accompanied by a decrease in blood flow in the arterial tree. The evaluation of cerebral venous insufficiency is an important diagnostic approach for the prognosis of the risk of developing cerebral hypotension and ICH.</p>

Assessment of some salivary enzymes levels in type 2 diabetic patients with chronic periodontitis (Clinical and biochemical study)
...Show More Authors

Background: Diabetic patients have been reported to be more susceptible to gingivitis and periodontitis than healthy subjects. Many intracellular enzymes like (alkaline phosphatase- (ALP), aspartate aminotransferase- (AST) and alanine aminotransferase- (ALT) that are released outside cells into the gingival crevicular fluid (GCF) and saliva after destruction of periodontal tissue during periodontitis. This study was conducted to determine the periodontal health status and the levels of salivary enzymes (ALP, AST and ALT) of the study and control groups and to correlate the levels of these enzymes with clinical periodontal parameters in each study group. Subjects, Materials and Methods: One hundred subjects were enrolled in the study, with a

Some Physiological Changes of Metronidazole Used to Treat Giardia lamblia in Human
...Show More Authors

The study aimed to introduce the effect of Giardia lamblia infection on changes in
some biochemical parameters in serum of infected patients before and after treatment during a
period of one year, (from Feb, 2008 to Jan, 2009).
Samples of 50 infected patients who referred to Al-Kadimiyah Teaching Hospital,
were collected before and after 7 days of treatment.
The activity of liver enzymes (Gpt and Got) before treatment increased significantly as
it reached up to (8.47) u/L and 19.06 u/L, comparing with control values (6.455) u/L and
(8.39) u/L respectively. The activity of the enzymes decreased after treatment but the values
of Gpt and Got remained higher than the control values as reached 7-27 u/L, 11-64 u/L

A Laboratory Study Attempt of Flow and Energy Dissipation in Stepped Spillways
...Show More Authors

A new laboratory study conducted on stepped spillways in order to investigate their efficiency of dissipating flow energy. All previous study on stepped spillway indicated that the flow energy dissipation decreased as increasing in discharge. Increasing in the step numbers and the spillway slope led to energy dissipation decrease. In this study, an experimental attempt to increase energy dissipation at variable discharges was performed on stepped spillway and that leads to decreasing the cost of initiating the stilling basin or may be ignoring it. Five spillways were constructed from concrete and tested to investigate and compare among them. Three were roughed by gravel with different size for each one, one of them was s

Assessment the Engineering Characteristics of the Smear Zone around PVDs Using Laboratory Tests
...Show More Authors

Smear zone is usually formed around the prefabricated vertical drains (PVD’s) due to mandrel driving. The geotechnical properties of the soil in this zone exhibit significant changes that affect the performance of the PVD’s. The most relevant property in this respect is the coefficient of permeability. So far, no serious attention is paid to investigate the effects of shearing under large shear strains on the geotechnical properties of the soft soil in Fao region. In this study, an extensive laboratory testing program was conducted to assess the characteristics of the smear zone with an emphasis on the permeability coefficient of Fao soft soil. The results show that the permeability of the smear zone is about 70% of
