Objective The aim of this study was to evaluate the angiosome of the superior and inferior labial arteries within the superior and inferior labia and to describe superior and inferior labial musculomucosal axial pattern flaps that can be used for intra-oral wound reconstruction. This study also presents the clinical use of a superior labial musculomucosal flap in a dog. Materials and Methods The common carotid arteries of six canine cadavers were injected with barium sulphate. The skin of the face and labial mucosa was removed and radiographed to study the vascular supply of the superior and inferior labia. Results The angiograms in all dogs demonstrated that the superior and inferior labial arteries were located within the musculomucosal layer of the labia. At the junction of the rostral and caudal half of the upper lip, extensive choke anastomoses joined the angiosome of the infra-orbital artery. The inferior labial artery perfused the caudal half of the lower labium and had extensive choke anastomoses with the middle and rostral mental arteries. Clinical Significance The musculomucosal flaps of the superior and inferior labia contain a rich arterial blood supply, which suggests that these flaps may survive in live dogs. The superior labial musculomucosal flap was successfully used to reconstruct a large cleft palate in a single clinical case.

Respiratory Sensitivity

The effect of CO2 on ventilation was studied in cross-circulated dogs. In these experiments the recipient dog's head was perfused exclusively by arterial blood from the donor dog through anastomoses of the common carotid arteries of the donor to the vertebral arteries of the recipient. The carotid arteries of the recipient dog, as well as its muscles in the neck, were tied. The injection of lipiodol and latex did not reveal leakage from the recipient's head to its body or vice versa. Ventilation and arterial Pco2 of both dogs were determined before, during, and after the inhalation of carbon dioxide of 3, 5, and 7% with 20% oxygen and balance nitrogen by the donor for 20 min or more. The sensitivity of the respiratory centers of both dogs to Pco2 was similar, as indicated by the regression lines relating ventilation in both dogs as a function of arterial Pco2 of the donor dog only. The blood of the recipient's body was hypocapnic when its head was receiving hypercapnic blood. The sensitivity coefficient in both dogs was similar to that of decerebrate dogs during CO2 inhalation. It is inferred that the central CO2 chemoreceptors can account for all the ventilatory response to CO2 inhalation.

Introduction: Cardiovascular disease (CVD) remains the number one cause of mortality in the western world. Carotid intimal media thickness (carotid IMT) is a safe and reliable predictor of future CVD risk. Hypothesis: The study aims to assess the hypothesis that lifestyle factors impact carotid IMT, and determine which nutrition and fitness risk factors best predict mean carotid IMT scores. Methods: A prospective cross-sectional analysis of 592 men and women undergoing health and cardiovascular risk screening. This study reflects the first visit of these subjects, age 23 to 65 (mean = 48.2), who are followed longitudinally and who were participants at a “wellness” oriented program for patients who are generally well-educated and mostly in good health. Measurements were made of fitness using VO2max stress testing and push-up and sit-up scores following the American College of Sports Medicine testing protocols, diet intake using a 3-day dietary intake survey and computerized analyses. Mean carotid IMT scores were obtained using high resolution B-mode ultrasonography of the common carotid arteries. Each subject had ≥10 images collected from the far wall of the right and left distal 1 cm of the common carotid arteries at end diastole. The carotid intimal thickness was measured as a continuous variable, using both multivariate linear and bivariate linear regression. Multivariate analyses adjusted for potential confounders using multiple linear regression and included measures of body composition, blood pressure, fasting lipid and glucose levels, and statin use. Results: Multivariate analyses show that higher mean carotid IMT values are associated with increasing age (p<0.0001), male gender (p<.0.0001), lower aerobic capacity (p=0.0045), lower intake of fish (p=0.05), and lower intake of zinc (p=0.0002). Bivariate analyses controlling for age and gender, with and without statin use, showed higher mean carotid IMT scores were statistically associated with lower levels of aerobic fitness, (p = 0.0007), lower intake of fiber (p=0.02) and lower intake of magnesium (p=0.019). Intake of protein, carbohydrate, and fat as percent of calories; as well as intake of saturated fat, sodium, calcium, potassium, and vitamin K; measures of strength (assessed with push-up and sit-up testing); and self-reported exercise minutes per week were not associated with mean carotid IMT scores. Conclusions: In this database, aerobic fitness and dietary intake of fiber, fish, magnesium, and zinc are associated with lower carotid IMT scores. Further studies are warranted to explore the impact of emerging lifestyle factors on cardiovascular risk and clinical outcomes.

The blood flow in arteries affects both the biology of the vessels and the development of atherosclerosis. The flow is three dimensional, unsteady, and difficult to measure or to model computationally. We have used phase-shift-based magnetic resonance angiography to image and measure the flow in the common carotid arteries of a healthy human subject. There was curvature of the vessels and thin-slice dynamic flow imaging showed evidence of the presence of secondary motions. Flexing the cervical spine straightened the vessels and reduced the asymmetry of the flow.

Aim. To study changes in structural and functional features of the common carotid arteries and central hemodynamic parameters under the influence of fosinopril at hypertensive patients depending on achieving target blood pressure.Material and methods. The study included 116 patients with essential hypertension. All patients underwent a general clinical study, an ultrasound scan of the common carotid arteries (CCA ) with the assessment of the structure and intravascular blood flow, and echocardiography with the definition of the parameters of central hemodynamic and intravascular, ambulatory blood pressure monitoring (ABPM) before the study and after 24 weeks of antihypertensive therapy angiotensin - converting enzyme fosinopril. Two groups of patients: the first group consisted of 74 people with the achievement of the targets of blood pressure (BP), the second 42 people who have not been achieved target BP levels.Results. In the first group there was a statistically significant decrease in the proportion of peripheral resistance, increased systolic index, distensibility coefficient of the common carotid arteries peak flow velocity. In the second group specific peripheral resistance was significantly increased, the thickness of the intima-media increased, decreased peak flow velocity.Conclusion. Effectiveness depends on fosinopril initial state total peripheral resistance, cardiac output, structural and functional features elastic arteries.
