Background. Xuzhou Qufu Shengji Ointment (QFSJO) has been used in hospital and private medication for more than 30 years to treat the infective wounds after trauma. However, molecular investigation is lacking. This study used rats to explore the healing mechanism of QFSJO in promoting wound healing in human. Methods. One circular incision was individually generated on the back of 30 rats in three groups and challenged with 108 CFU (0.3 mL) of Staphylococcus aureus. Then, one of the trauma groups was treated with QFSJO gauze, and the control group was covered with a piece of Vaseline gauze, while the western medicine group was treated with erythromycin in a similar way. The dressing change of all the groups was performed once a day for three weeks. The anti-inflammation and proangiogenesis of QFSJO were evaluated by enzyme-linked immunosorbent assay (ELISA). The levels of angiogenesis associated factors, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (b-FGF), hydroxyproline, and hemoglobin, were measured according to ELISA. The immunohistochemistry of CD31 and CD34 expression in granulation tissue was demonstrated and quantitatively analyzed for angiogenesis in granulation tissue in sites. Results. A faster wound healing ratio was observed in QFSJO-dressing-treated group than Vaseline- and erythrocin-treated groups. ELISA results showed that QFSJO promoted VEGF and b-FGF levels significantly in early stage of wound healing. QFSJO dressing group also showed an enhanced hydroxyproline and hemoglobin in granulation tissue. The expressions of CD31 and CD34 in granulation tissue of QFSJO group were higher than in the Vaseline and erythrocin groups. Conclusion. QFSJO improved the healing rate of the infective wounds by promoting the angiogenesis of granulation tissue and inhibiting the inflammation of the trauma tissue. Our finding suggests that QFSJO is able to help angiogenic capillary sprouts for collagen accumulates in the granulation tissue.

Background: Pre-eclampsia(PE) is  the  most  frequently encountered  medical  complication  during  pregnancy. In developing countries PE   is a principal cause of maternal mortality. A disturbance  in  the  angiogenic/antiangiogenic  factors  and  in  the  hypoxia/placental re-oxygenation  process,  seems  to  activate a maternal  endothelial  dysfunction.Aims and Objective: To estimate Vascular Endothelial Growth Factor ( VEGF )  level  in the cord blood of healthy and Preeclamptic ( PEc ) pregnant women and to associate this with Preeclamptic pregnancy.Material and Methods: A case-control study ofUmbilical cord serum VEGF levels from women with uncomplicated pregnancies (control group, n=60) and pregnancies complicated by Pre-eclampsia (n=40). VEGF in the cord serum was estimated by SANDWICH Enzyme Linked Immunosorbent Assay method by using ELISA Kit and then compared between the two groups.Results: The mean VEGF concentrations in the women who had pre-eclampsia  (578.62±468.3)  were lower than in the control group( 625.75±533.1) , but the difference was not statistically significant ( p= 0.8548).  Conclusion VEGF plays a key role in the instability between endothelial dysfunction and angiogenesis that occurs during Preeclampsia.  VEGF levels might be a useful tool for the early diagnosis of Pre-eclampsia.Asian Journal of Medical Sciences Vol.8(1) 2017 21-25

Angiogenesis plays a major role in the development and progression of haematological malignancies. In our study we measured plasma concentrations of key angiogenic activators vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) using comercially available sandwich enzyme-linked immunosorbent assay (ELISA) in 37 patients with lymphoid malignancies and 20 healthy donors. We found a statistically significant increase in bFGF concentrations in patients with B-cell chronic lymphocytic leukemia (B-CLL, n=18) compared to the control group (median 118.8 vs. 9.3 pg/ml, p<0.001). However, we didn’t find any significant difference in VEGF concentrations between B-CLL patients and the control group. There was also no significant increase in bFGF or VEGF in patients with multiple myeloma (n=7) and non-Hodgkin’s lymphoma (n=12). Our pilot study shows that measurement of angiogenic activators in plasma is a feasible and reproducible method of angiogenesis assessment. Larger studies are needed for correlation between serum and plasma concentrations and detailed statistical evaluation including the impact on patients’ survival.

The objective of this study was to measure the vascular endothelial growth factor (VEGF) levels in dogs diagnosed with chronic superficial keratitis (CSK). The study was performed on 25 German shepherds (14 males and 11 females, aged between 3 and 11 years). The VEGF levels were determined in blood serum using commercially available enzyme-linked immunosorbent assay (ELISA; Quantikine Canine VEGF Immunoassay, R&D Systems). The test group of affected German shepherds was subdivided into two subgroups, based on the area of corneal neovascularisation. The first subgroup (9 patients) comprised dogs with neovascularisation observed in 1 to 2 quadrants of the right and left cornea, while the second subgroup (16 patients) comprised dogs with neovascularisation observed in 3 to 4 quadrants of the right and left cornea. The control group comprised 12 clinically healthy German shepherds (7 males and 5 females, aged between 3 and 9 years). The results were then statistically analysed by the Mann-Whitney test. The study indicated that the median serum VEGF concentration in healthy dogs was 14.9 pg/mL. The VEGF level observed in sick German shepherds was elevated (19.5 pg/mL) as compared to the values found in healthy dogs; however, a statistically significant increase in VEGF concentration, as compared to the values observed in healthy dogs, was only noted in the first subgroup, where the median VEGF concentration was 22.0 pg/mL. Elevated serum VEGF concentration was observed in German shepherds diagnosed with CSK. A statistically significant increase in VEGF levels was observed in dogs in the first stage of the disease, i.e. the early stage of neovascularisation.

Background: Methenamine is a worldwide antibacterial agent for urinary system infections in human and animals. The effect of methenamine consumption during early phase of pregnancy is not fully clarified in previous studies. Vascular development is the essential part of the early embryonic growth. Objective: In this study, we used chicken chorioallantoic membrane to evaluate the effects of methenamine administration on angiogenesis process as a model. Materials and Methods: In this experimental study, 20 Ross 308 eggs (mean weight 55 ± 4) were incubated. The eggs were divided into two equal groups (n = 10/each). In the first group, methenamine (150 mg/kg egg weight) was injected on the shell membrane, and in the second group (control group) phosphate-buffered saline as injected. Methenamine was inoculated at 96 and 120 hr after incubation; 24 hr after the last inoculation, the eggs were removed and the egg’s shell was incised. Then, the development of vascular network and vascular endothelial growth factor A expression was evaluated. Results: Angiogenesis was significantly decreased after methenamine treatment. The indexes such as areas containing vessels, the vessels’ length, the percentage of angiogenesis developing areas, and vascular complexity in the treatment group receiving methenamine were significantly reduced compared to the control group. Vascular endothelial growth factor A expression was suppressed in the methenamine treated group. Conclusion: According to the achieved results, it was defined that methenamine could have an inhibitory effect on the growth and development procedures of extraembryonic vasculature. Key words: Methenamine, Angiogenesis modulating agents, Vascular endothelial growth factor A, Extraembryonic membranes.

Nerve growth factor (NGF) has been reported to increase the mRNA expression of vascular endothelial growth factor (VEGF) in granulose cells of human, rat via TrkA signaling; VEGF has been shown to exert beneficial effects during bovine in vitro maturation (IVM) as well as early embryonic development. The aims of this study were 1) to investigate not only the direct effect of NGF but also the collaborative effect of NGF and VEGF during bovine in vitro maturation (IVM), in vitro culture (IVC), or both; and 2) to validate the correlation among transcript abundance of 7 genes (VEGF164, VEGF120, Flt-1, Flk-1, TrkA, PTGS2, and CYP11A1) in bovine cumulus cells and the results of IVM or IVC among the differently treated groups. In Experiment 1, concentrations of 0, 10, and 100 ng mL–1 NGF were added to our established IVM medium without serum, and in Experiment 2, control and treatment groups (concentration of 0, 10, and 100 ng mL–1 NGF with VEGF 100 ng mL–1) were added into chemically defined media. The oocytes of each group in Experiments 1 and 2 were determined by the proportion of MII oocytes after 24 h, and embryos were assessed after parthenogenetic activation. Cumulus cells from the differently treated matured cumulus cell–oocyte complexes (COC) were separated and synthesised into cDNA for RT-PCR and real-time PCR in order to measure relative abundance of 7 genes in a dose-dependent manner or a time-dependent manner. In Experiment 1, the concentration of 10 ng mL–1 (57.40%) and 100 ng mL–1 (62.75%) NGF treatment groups did not significantly increase the proportion of MII oocytes compared with the control group (55.06%). In Experiment 2, both the NGF 10 ng mL–1 with VEGF 100 ng mL–1 treated group (67.69%; P ≤ 0.01) and the NGF 100 ng mL–1 with VEGF 100 ng mL–1 treated group (72.24%; P ≤ 0.001) had a significantly higher percentage of polar body extrusion than control group (51.77%) and the group which was treated with VEGF 100 ng mL–1 (56.39%). The NGF treatment group with VEGF increased transcriptional level of VEGF164 and VEGF120 compared with the control group and only NGF- or VEGF-treated groups. In addition, either the NGF-treated group or NGF plus VEGF showed significantly increased mRNA abundance in VEGF164, VEGF120, Flt-1, Flk-1, and TrkA genes, whereas the NGF plus VEGF-treated group indicated the up-regulation of VEGF164, VEGF120, CYP11A1, and PTGS2 genes. In conclusion, NGF and exogenous VEGF have a synergic effect during bovine IVM and the early stage of embryo development; the elevated VEGF mRNA abundance in cumulus cells might contribute to the viability of bovine oocytes and early embryonic development.

Abstract The vascular endothelial growth factor (VEGF) is a multifunctional cytokine stimulating the growth of vascular endothelial cells, survival and proliferation, inhibiting apoptosis. It is one of the most potent stimulants of vascular permeability. VEGF is found at high levels in inflammatory and tumour-associated pleural and abdominal effusions and is involved in their occurrence. In the present study, the blood plasma and abdominal fluid VEGF levels were assayed in thirty-one client-owned dogs with neoplastic and non-neoplastic diseases by means of enzyme-linked immunosorbent assay (ELISA). The VEGF concentration in abdominal fluid of dogs (n=6) with ascites was 190.70±34.35 pg/ml, in dogs (n=6) with peritonitis: 1449.81±365.42 pg/ml and in dogs (n=9) with tumour-associated effusion: 1993.13±202.56 pg/ml. Blood plasma VEGF of healthy dogs (control group, n=10) was 36.79±5.72 pg/ml, in dogs with ascites: 57.92±2.88 pg/ml, in dogs with peritonitis: 76.98±7.24 pg/ml and in dogs with tumour-associated effusion: 173.50±40.9 pg/ml. There were substantial differences between blood plasma and abdominal fluid VEGF levels.

Abstract The aim of the study was to determine the levels of the vascular endothelial growth factor (VEGF) in the serum of dogs suffering from splenic malignant tumours, prior to splenectomy, as well as three and six months after the surgery. Tumours and blood samples were collected from 10 dogs of various breeds, aged between 7 and 13 years, and from 10 control animals. Tumour sections were fixed in 10% buffered formalin for 24 h. The type of tumour was determined according to the WHO classification. Blood samples were centrifuged and the obtained sera were subjected to immunoenzymatic assays to determine the VEGF levels. The median of VEGF levels in the serum of dogs suffering from splenic malignant tumours was 37.85 pg/mL (15.40-107.18 pg/mL). The highest values were observed in dogs with confirmed metastases (107.18 pg/mL and 65.43 pg/mL). The VEGF values in control group were between 0.1 pg/mL and 13.04 pg/mL. A comparative analysis of the VEGF levels against the animals' survival time indicated that VEGF overexpression may serve as a prognostic factor in cases of malignant tumours of the spleen.
