Introduction: This study aimed to investigate the effect of low-level laser therapy (LLLT) on the blood cell count when applied to parotid glands of rats irradiated by volumetric modular arc therapy (VMAT). Methods: Thirty-two adult male Wistar rats were used in this study. Samples were randomly assigned to three groups: control group (CG, n = 8), immediate laser group (24 hours) (ILG, n=12), and late laser group (120 hours) (LLG, n=12). The two laser groups were previously subjected to VMAT radiotherapy in a single dose of 12 Gy. LLLT with an AsGaAl laser (660 nm, 100 mW) was applied at three points in the region of the parotid glands, right side, with the energy of 2 J per point (20s, 70 J/cm2 ) and a spot size of 0.0028 cm2 for 10 consecutive days. In the euthanasia, blood samples were obtained by cardiac puncture. The samples from each group were processed by an automatic method and analyzed for erythrogram, leukogram and platelet count values. The data were analyzed by ANOVA and each LLLT time point was analyzed in relation to the control group, with a significance level less than 0.05. Results: Groups using LLLT had higher red blood cell counts, being higher in the LLG (p = 0.000). The hematimetric indices MCV (P=0.002) and MCH (P=0.009) were lower than the control group, especially when compared to the group using LLLT 120h after radiotherapy (LLG). White blood cell counts were lower in the groups with radiotherapy and immediate use of LLLT (ILG) (P=0.011), mainly at the expense of lymphocytes (P=0.002). Conclusion: The results suggest a potential systemic effect of LLLT, especially on circulating red blood cell counts, regardless of their time of immediate or late use of radiotherapy.

ABSTRACT Ozone (O3) therapy has been used for medical procedures for centuries; however, there are no extensive studies on its utilization in horses. This study aimed to evaluate the application of transrectal O3 on horses by physical and laboratorial evaluation, and production of reactive oxygen species (ROS). Sixteen healthy horses were separated in two groups: a control group (CG) and a group treated with O3 (TG). The TG animals received 1L of an oxygen and O3 mixture transrectally. The initial dose was 10µg/ml for the first two applications, 15μg/ml for the following two applications, and 20μg/ml for the next six applications. The CG animals received 1L of oxygen transrectally. In TG animals no variations in the physical examination were detected; furthermore, TG animals did not exhibit changes in biochemical evaluation results, fibrinogen concentrations, or ROS production. TG animals had increased red blood cell counts, hemoglobin concentrations, and packet cell volume values in comparison to the baseline and CG values. We could infer that O3 affected the red blood cell counts and improved rhetological properties of the blood. The transrectal application of O3 in horses is safe and can indirectly improve the oxygenation and metabolism of tissues.

The purpose of this study was to evaluate whether Low-Level Laser Therapy (LLLT) improves the healing of the implant surgical site with clinical and biochemical parameters.Thirty patients with an edentulous space spanning a single tooth were selected. The patients were randomly allocated to two groups - the control group and the test group. The test group received laser energy at a power of 2J/cm 2 with a total of 4-6J energy over each implant. Clinical parameters (Implant Stability Quotient, probing index, modified sulcus bleeding index)and osteoprotegerin (OPG) were assessed at baseline and follow-up intervals (2 weeks, 6 weeks, and 3 months).The test group showed significantly higher implant stability quotient compared to thecontrol group at 2 weeks(57.93±3.95 and 35.67±3.08; p<0.01) and 3months(58.86±3.75 and 67.06±3.78; p<0.01). A significant rise in OPG levels of the test group(686.30±125.36pg/ml at baseline and 784.25±108.30pg/ml at 3months;p<0.01) was seen contrary to significant decline in the control group (839.50±249.08pg/ml at baseline,415.30±78.39pg/ml at 3months;p<0.01). Within the limitations of the study, the study suggests that the healing of peri-implant hard and soft tissues may be enhanced with the use of LLLT as an explicit modality during the post-operative period.

Talinum Triangulare

The effects of Talinum triangulare on the haematological indices of Clarias gariepinus was investigated. T. triangulare leaf powder at 0, 0.5, 1.0, and 3.0% concentrations were fed to Clarias gariepinus juveniles (n=84; 117.3 ± 1.57 g; 26.70 ± 0.26 cm) as feed additive for a period of six (6) weeks.  The packed cell volume (PCV) and Haemoglobin (Hb) concentration values, 34.67 ± 0.67%, 12.03 ± 0.26g/dl, respectively observed in the group fed with 1.0% were significantly higher (P<0.05) compare with the control group. Red blood cell counts (RBCs), white blood cell counts (WBCs), lymphocytes, MCV, MCH and MCHC recorded were marginally different (P>0.05) among the groups, were within standard for Clarias gariepinus, therefore adjudged not to indicate a negative physiological effect on the experimental fish. Blood indices values observed revealed that the varying additive levels of T. triangulare used had no negative physiological stress on the health status of the fish studied and haematological values observed were seen to be best in the group fed 1.0% T. triangulare. It could be recommended that 10g/kg of Talinum triangulare leaf powder be included in the diet of Clarias gariepinus for boosting of the animal blood and treatment of disease conditions such as anaemia.

Abstract Objectives Serum lipids may influence the lifespan of erythrocytes, and have been associated with clinical erythrocyte indices at the population level. Consumption of whole eggs vs. egg whites exerts varying effects on serum lipids and lipoprotein profiles; therefore, we investigated whether egg-induced changes in serum lipids correspond to changes in clinical erythrocyte markers. Methods Young, healthy men and women (18–35y, BMI < 30 kg/m2, n = 11) were recruited to participate in an ongoing intervention trial. All subjects followed an egg-free diet for 4 weeks, then were randomized to consume either 3 whole eggs or 3 egg whites per day for 4 weeks. Fasting serum lipids, complete blood cell counts, and dietary intake analysis was performed at the end of each study period. Results Average serum lipids and erythrocyte indices were within normal ranges at the end of each diet period. Changes in total cholesterol following the whole egg (+4.8%) and egg white (0.4%) diet period were not significant as compared to the egg-free diet period. Similarly, clinical erythrocyte markers were not significantly altered by daily consumption of whole eggs or egg whites. However, changes in total cholesterol and LDL-cholesterol between diet periods were positively correlated with changes in total red blood cell counts and hemoglobin. Total cholesterol was additionally correlated with hematocrit levels, and negatively associated with red cell distribution width. Total red blood cell counts and hemoglobin were further correlated with changes in the total cholesterol to HDL-cholesterol ratios, but not HDL-cholesterol alone. Conclusions Our findings indicate that egg-induced changes in serum lipids are associated with clinical erythrocyte indices, and that total cholesterol levels and dyslipidemia may be more significant determinants of erythrocyte profiles.

Bottlenose dolphins, Tursiops truncatus, can be separated into coastal and offshore ecotypes based upon hemoglobin levels, packed cell volumes, and red blood cell counts, the offshore form having higher values for all three measures. Captive-bred crosses between coastal and offshore types produce animals with intermediate hematologic profiles suggesting a significant genetic basis for these differences.
