Effect of Low-Level Laser Therapy and Calcitonin on Bone Repair in Castrated Rats: A Densitometric Study

Objective: To investigate the healing of bone defects in male rats treated with salmon calcitonin, low-level laser therapy (LLLT), or both. Background: Healing of bone defects still represents a challenge to health professionals in several areas. In this article, the effect of calcitonin in combination with LLLT on bone repair was studied. Densitometry was used as a valuable tool for the measurement of bone regeneration. Methods: Sixty male Wistar rats underwent bilateral castration surgery before the creation of a surgical bone defect. The animals were randomly divided into four groups: control, treated with calcitonin (Ca), treated with LLLT (La), and treated with calcitonin and LLLT (CaLa). Groups Ca and CaLa received 2 IU/kg of synthetic salmon calcitonin intra-muscularly three times a week. Groups La and CaLa received laser therapy using a gallium-aluminum-arsenide laser (10mW, 20 J/cm(2), wavelength 830 nm). Control animals were submitted to sham irradiation. The animals were sacrificed 7, 14, and 21 days after surgery, and bone defects were analyzed using densitometry. Results: The CaLa group had a higher degree of bone regeneration 14 and 21 days after surgery. Conclusions: The La and CaLa had significantly higher bone mineral density than the control and Ca groups.

In vitro Anthelmintic effect of Melia azedarach L. and Triclinia claussenii C. against sheep gastrointestinal nematodes

The control of parasitic diseases in small ruminants is mainly done with the use of synthetic anthelmintics. However, incorrect and indiscriminate use of these products has caused the emergence of parasite resistance. Plants with anthelmintic activity are used in folk veterinary medicine, but it is necessary to investigate and scientifically validate low-cost phytotherapeutic alternatives for future use to control gastrointestinal nematodes in small ruminants by family farmers. Thus, the aim of this study was to evaluate the in vitro anthelmintic effect of plant extracts from Melia azedarach and Trichilia claussenii by the egg hatch test (EHT) and larval development test (LDT) against sheep gastrointestinal nematodes. The hexane extract of M. azedarach fruits was extracted through cold percolation and the methanol extract of T. claussenii leaves was obtained by extraction at room temperature in solvents in order of increasing polarity. The efficacy results were analyzed using the Probit program of SAS. The M. azedarach extract showed a LC50 of 572.2 mu g/mL and LC99 of 1137.8 mu g/mL in the EHT, and LC50 of 0.7 mu g/mL and LC99 of 60.81 mu g/mL in the LDT. In turn, the T. claussenii extract presented a LC50 of 263.8 mu g/mL and LC99 of 522.5 mu g/mL in the EHTand LC50 of 1.11 mu g/mL and LC99 of 26.4 mu g/mL in the LDT. Comparing the extracts of the species from the Meliaceae family, T. claussenii showed greater anti-parasite potential in vitro than M. azedarach. However, studies on the isolated compounds, toxicity and administration forms to animals are also needed to validate low-cost alternative herbal remedies for use to control gastrointestinal nematodes by family farmers.

Heparin and dextran sulfate: their role on rsv infectivity

Respiratory syncytial virus is the major cause of acute lower respiratory tract illness in infants and young children. Because there is currently no licensed vaccine for RSV, there is a substantial interest in the identification and development of RSV specific inhibitory agents. There are clinical evidences that glycosaminoglycans (GAGs) are potential inhibitors of viral infection. In this study, the performance of two GAGs (heparin and dextran sulfate) were compared for their antiviral and virucidal activities on RSV. Analysis was performed using an in vitro infection model where, previously to infection, Hep-2 cells or RSV were incubated with heparin or dextran sulfate. The presence of viral particles was analyzed by Reverse Transcriptase-Polimerase Chain Reaction (RT-PCR) and indirect immunofluorescence assays (IFA). The results showed that viral infection was more efficiently inhibited when Hep-2 cells were pre-incubated with heparin or, when viral particles were pre-incubated with dextran sulfate. Our study suggest that, in the absence of cellular death, heparin and dextran sulfate reduce RSV infection by different mechanisms, antiviral and virucidal ones, respectively. These data contribute for recent medical, microbiology and biochemical studies which suggest that the use of antiviral and virucidal compounds as more effective treatment to control virus infections.
