Abstract
AIM Muscular flaps are considered by many surgeons as a treatment of choice for pressure sores. Nevertheless fasciocutaneous and adipofascial flaps are less sensitive to ischemia, more resistant to pressure and have higher mechanical resistance. The aim of this study is to evaluate the results of our integrated rehabilitative and surgical protocol in pressure sore management based on the use of cutaneous flaps. MATERIAL OF STUDY Since 1998, we treated 338 pressure sores (PS) in 195 patients (120 males; 75 females), 189 patients were affected by paraplegia and tetraplegia and 6 of them by neurological disorders. RESULTS Ninety sacral, 156 ischiatic, 75 trochanteric, 9 calcanean and 8 sores of the iliac-crest were succesfully treated. All showed an involvement of the bone element, with osteitis and/or periosteitis. 14 cases of trocanteric sores showed a deeper bone involvement, with evidences of osteomyelitis. Follow up ranges from 7 years to 2 months. Median time for wound healing was 18 days. DISCUSSION The use of fasciocutaneous flaps, as an alternative to the traditional muscolocutaneous flaps in the treatment of pressure sores leads to good and statistically comparable, healing rate, time and incidence of complications. Reconstructive plastic surgery as is a decisive factor to reach a good rehabilitative outcome, minimizing the time of rehabilitation with a following decrease of hospitalization costs. In spinal cord injured patients, surgical treatment of pressure sores is not proposed as the main procedure, but it is an important stage during the natural history of pressure sores. CONCLUSIONS Cutaneous, adipofascial and fasciocutaneous flaps are less invasive, of a relatively easy execution, provided by a reliable vascular pedicle and they could be "re-used" in case of recurrences.

Abstract
Cardiovascular diseases are more prevalent in patients with chronic kidney disease than in the general population and they are considered the leading cause of death in patients with end-stage renal disease. The discovery that vitamin D3 plays a considerable role in cardiovascular protection has led, in recent years, to an increase in the administration of therapies based on the use of this molecule; nevertheless, several studies warned that an excess of vitamin D3 may increase the risk of hypercalcemia and vascular calcifications. In this study we evaluated the effects of vitamin D3, and of its selective analog paricalcitol, on immature cardiomyocytes. Results show that vitamin D3 induces cAMP-mediated cell proliferation and significant intracellular calcification. Paricalcitol, however, induces cell differentiation, morphological modifications in cell shape and size, and no intracellular calcification. Furthermore, vitamin D3 and paricalcitol differently affect cardiomyoblasts responses to acetylcholine treatment. In conclusion, our results demonstrate that the effects of vitamin D3 and paricalcitol on cardiomyoblasts are different and, if these in vitro observations could be extrapolated in vivo, they suggest that paricalcitol has the potential for cardiovascular protection without the risk of inducing intracellular calcification.

Abstract
OBJECTIVE To evaluate the effects the administration of myo-inositol (MYO) on hormonal parameters in a group of polycystic ovary syndrome (PCOS) patients. DESIGN Controlled clinical study. SETTING PCOS patients in a clinical research environment. PATIENTS 50 overweight PCOS patients were enrolled after informed consent. INTERVENTIONS All patients underwent hormonal evaluations and an oral glucose tolerance test (OGTT) before and after 12 weeks of therapy (Group A (n¼10): MYO 2 g plus folic acid 200 mg every day; Group B (n¼10): folic acid 200 mg every day). Ultrasound examinations and Ferriman-Gallwey score were also performed. MAIN OUTCOME MEASURES Plasma LH, FSH, PRL, E2, 17OHP, A, T, glucose, insulin, C peptide concentrations, BMI, HOMA index and glucose-to-insulin ratio. RESULTS After 12 weeks of MYO administration plasma LH, PRL, T, insulin levels and LH/FSH resulted significantly reduced. Insulin sensitivity, expressed as glucose-to-insulin ratio and HOMA index resulted significantly improved after 12 weeks of treatment. Menstrual cyclicity was restored in all amenorrheic and oligomenorrheic subjects. No changes occurred in the patients treated with folic acid. CONCLUSIONS MYO administration improves reproductive axis functioning in PCOS patients reducing the hyperinsulinemic state that affects LH secretion.

Abstract
AIM We present a two stage reimplantation technique for infected total knee arthroplasty using a muscular gastrocnemious spacer that allows delivery of high local concentrations of antibiotics in absence of heterologous materials associated with high percentage of infection. MATERIAL OF STUDY Between January 2009 and June 2011 we selected 8 patients with diagnosis of total knee arthroplasty deep infection. All patients underwent a surgical protocol that consisted of a two stage procedure with harvesting of medial gastrocnemious rotational flap followed by delayed reimplantation of prosthesis. All of them received 6 weeks of tailored intravenous antibiotics suggested by the infectious disease consultant and none had positive cultures at the time of reimplantation. RESULTS The outcome was considered excellent for 6 of the 8 knees, good for 1, fair for 1, and poor for 0 joint. The reimplantion procedures were completely successful in all cases and all patients were able to walk again after rehabilitation program. DISCUSSION Our surgical protocol guarantees wound healing without presence of disuse osteoporosis nor joint stiffness with scar tissue obliterating joint space. Moreover it shows a lower percentage of reinfection. This is connected to the presence of remaining microbiological organisms at the moment of closure that can develope a biofilm that adheres to biomaterial surfaces, enabling a complete bacterial eradication. The gastrocnemious muscle plays either the role of a natural spacer, either the function of coverage and protection of the new joint articulation after the reimplantation of the new device. CONCLUSIONS The surgical and medical protocol used in our study resulted in clinical absence of infection in all our patients with lower postoperative complications in relation to the complete eradication of infection.

Abstract
We developed a modified transcranial sonography technique to study the morphology of the temporal lobe, a brain region involved in language, memory and social functions in humans that can be visualized in correspondence of the acoustic window of the temporal squama. Previous studies raise the possibility that a unique derived feature of Homo sapiens is a relatively larger temporal lobe compared to those of other hominins and apes. Such a brain reorganization might have contributed to the evolution of various "higher" cognitive functions of Homo sapiens, including language. Hence, the importance of further comparative analyses of the temporal region. With the technique that we developed we were able to study the meninges, the subarachnoidal space and the cortex of the human temporal lobe. The spatial resolution and the ability to visualize structures of 200-300 microm size led us to hypothesize that the linear structures parallel to the subarachnoidal space might be referred to the neuronal layers of the cortex. The low cost, simplicity and safety of the procedure suggest that this technique may have a significant potential in the comparative study of the primate temporal lobe. Furthermore, the procedure described here can also be used for the study of vascularization of the meninges, in order to better understand the evolutionary relationships between the neurocranial shape and the middle meningeal vessels in living and fossil human species.

Abstract
BACKGROUND AND OBJECTIVE In patients with advanced cancer, cachexia correlates with low performance status and poor quality of life. In addition, cachexia may be associated with reduced response to chemoradiotherapy and a poor prognosis in cancer patients. Nearly all forms of cachexia are closely associated with chronic inflammation and elevated levels of inflammatory and pro-inflammatory circulating factors, including C-reactive protein (CRP), which is considered a valid laboratory and clinical marker. Among the different pathways involved in the production of inflammatory cytokines and chemokines, the vitamin D-vitamin D receptor (VDR) axis plays a fundamental role. In this study, we explore the possible association between CRP and key factors pertaining to the vitamin D axis--in particular, VDR gene polymorphisms--in cancer patients with cachexia. Although certain tumor types are more commonly associated with cachexia, even within the same tumor type there are significant differences in the extent and duration of cachexia. Such variations may be due to polymorphisms of the VDR gene that could lead to cachexia-prone genotypes or to cachexia-resistant genotypes. Identification of such genotypes could be very helpful in the management of cancer patients. METHODS Forty-three cancer patients were recruited by the Nutritional Unit of the Prato Hospital. Data on age, gender, type of cancer, stage of cancer, and nutritional assessment, as well as transferrin, ferritin, albumin, and CRP levels, were collected. Genomic DNA was extracted from peripheral blood leukocytes and amplified by polymerase chain reaction. BsmI, ApaI, TaqI, and FokI polymorphisms of the VDR gene were investigated using the respective restriction enzymes. For the different VDR polymorphisms, the absence or presence of the restriction sites were designated with capital or small letters, respectively. For example, for the BsmI polymorphism, the presence of the undigested fragment identified the B allele, whereas the presence of the digested fragment identified the b allele. RESULTS Cancer patients with cachexia have higher CRP levels compared with non-cachectic cancer patients, independently from the genotype. In cachectic patients, the presence of specific VDR BsmI and TaqI alleles was associated with higher CRP levels. In particular, the VDR b and T alleles were more frequent in cachectic cancer patients with elevated CRP levels than in cachectic patients with normal CRP levels. CONCLUSION From these results, we hypothesize that there is an association between BsmI and TaqI VDR gene polymorphisms and the cachectic syndrome. In particular, we propose that in cancer patients, the concomitance of b and T alleles with elevated CRP levels may represent an early clinical predictor for the development of a more aggressive form of cachexia.

Could cadmium be responsible for some of the neurological signs and symptoms of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome. Med Hypotheses 2012; 79:403-7.

Abstract
According to the World Health Organization, Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a neurological disease characterized by widespread inflammation and multi-systemic neuropathology. Aetiology and pathogenesis are unknown, and several agents have been proposed as causative agents or as factors perpetuating the syndrome. Exposure to heavy metals, with particular reference to mercury and gold in dental amalgams, has been considered among the triggers of ME/CFS. Here we hypothesize that cadmium, a widespread occupational and environmental heavy metal pollutant, might be associated with some of the neurological findings described in ME/CFS. In fact, ME/CFS patients show a decrease of the volume of the gray matter in turn associated with objective reduction of physical activity. Cadmium induces neuronal death in cortical neurons through a combined mechanism of apoptosis and necrosis and it could then be hypothesized that cadmium-induced neuronal cell death is responsible for some of the effects of cadmium on the central nervous system, i.e. a decrease in attention level and memory in exposed humans as well as to a diminished ability for training and learning in rats, that are symptoms typical of ME/CFS. This hypothesis can be tested by measuring cadmium exposure in a cohort of ME/CFS patients compared with matched healthy controls, and by measuring gray matter volume in un-exposed healthy controls, exposed non-ME/CFS subjects, un-exposed ME/CFS patients and exposed ME/CFS patients. In addition, we hypothesize that cadmium exposure could be associated with reduced cerebral blood flow in ME/CFS patients because of the disruptive effects of cadmium on angiogenesis. In fact, cadmium inhibits angiogenesis and low global cerebral flow is associated with abnormal brain neuroimaging results and brain dysfunction in the form of reduced cognitive testing scores in ME/CFS patients. This hypothesis can be tested by measuring cerebral cortex blood flow in un-exposed healthy controls, exposed non-ME/CFS subjects, un-exposed ME/CFS patients and exposed ME/CFS patients. If our hypothesis is demonstrated correct, the consequences could affect prevention, early diagnosis, and treatment of ME/CFS. Implications in early diagnosis could entail the evaluation of symptoms typical of ME/CFS in cadmium-exposed subjects as well as the search for signs of exposure to cadmium in subjects diagnosed with ME/CFS. Nutritional supplementation of magnesium and zinc could then be considered, since these elements have been proposed in the prophylaxis and therapy of cadmium exposure, and magnesium was demonstrated effective on ME/CFS patients' symptom profiles.

Abstract
BACKGROUND Searching for additional therapeutic tools to fight breast cancer, we investigated the effects of vitamin D-binding protein-derived macrophage activating factor (DBP-MAF, also known as GcMAF) on a human breast cancer cell line (MCF-7). MATERIALS AND METHODS The effects of DBP-MAF on proliferation, morphology, vimentin expression and angiogenesis were studied by cell proliferation assay, phase-contrast microscopy, immunohistochemistry and western blotting, and chorioallantoic membrane (CAM) assay. RESULTS DBP-MAF inhibited human breast cancer cell proliferation and cancer cell-stimulated angiogenesis. MCF-7 cells treated with DBP-MAF predominantly grew in monolayer and appeared to be well adherent to each other and to the well surface. Exposure to DBP-MAF significantly reduced vimentin expression, indicating a reversal of the epithelial/mesenchymal transition, a hallmark of human breast cancer progression. CONCLUSION These results are consistent with the hypothesis that the known anticancer efficacy of DBP-MAF can be ascribed to different biological properties of the molecule that include inhibition of tumour-induced angiogenesis and direct inhibition of cancer cell proliferation, migration and metastatic potential.

Abstract
We evaluated the association between 2 genetic polymorphisms known to be involved in fitness and performance, and anthropometric features, body composition, and athletic performances in young male soccer players with the goal of identifying genetic profiles that can be used to achieve maximal results from training. One hundred twenty-five medium-high-level male soccer players were genotyped for angiotensin-converting enzyme (ACE) I/D, and vitamin D receptor (VDR) FokI gene polymorphisms and scored for anthropometric measurements, body composition, and athletic performance. Body mass index, fat mass, fat-free mass, resistance, reactance, impedance, phase angle (PA), and body cell mass were measured. Athletic performance was evaluated by squat jump, countermovement jump (CMJ), 2-kg medicine ball throw, 10- and 20-m sprint time. We observed that the homozygous ff genotype of the VDR gene was significantly more represented in young soccer players than in a matched sedentary population. Values of reactance and PA were differently distributed in ACE and VDR genotypes with high mean values in subjects with DD (ACE) and FF (VDR) genotypes. No correlation was observed between ACE or VDR genotypes and 2-kg medicine ball throw, 10- and 20-m sprint times. The ID genotype of ACE was associated with the best performances in squat jump and CMJ. Our results suggest that determination of ACE and VDR genotypes might help select those young athletes harboring the most favorable genetic potential to succeed in soccer.

Abstract
The effects of Gc protein-derived macrophage-activating factor (GcMAF) have been studied in cancer and other conditions where angiogenesis is deregulated. In this study, we demonstrate for the first time that the mitogenic response of human peripheral blood mononuclear cells (PBMCs) to GcMAF was associated with 3'-5'-cyclic adenosine monophosphate (cAMP) formation. The effect was dose dependent, and maximal stimulation was achieved using 0.1 ng/ml. Heparin inhibited the stimulatory effect of GcMAF on PBMCs. In addition, we demonstrate that GcMAF (1 ng/ml) inhibited prostaglandin E(1)- and human breast cancer cell-stimulated angiogenesis in chick embryo chorionallantoic membrane (CAM) assay. Finally, we tested different GcMAF preparations on CAM, and the assay proved to be a reliable, reproducible and inexpensive method to determine the relative potencies of different preparations and their stability; we observed that storage at room temperature for 15 days decreased GcMAF potency by about 50%. These data could prove useful for upcoming clinical trials on GcMAF.

Abstract
Since the discoveries of a putative AIDS virus in 1984 and of millions of asymptomatic carriers in subsequent years, no general AIDS epidemic has occurred by 2011. In 2008, however, it has been proposed that between 2000 and 2005 the new AIDS virus, now called HIV, had killed 1.8 million South Africans at a steady rate of 300,000 per year and that anti-HIV drugs could have saved 330,000 of those. Here we investigate these claims in view of the paradoxes that HIV would cause a general epidemic in Africa but not in other continents, and a steady rather than a classical bell-shaped epidemic like all other new pathogenic viruses. Surprisingly, we found that South Africa attributed only about 10,000 deaths per year to HIV between 2000 and 2005 and that the South African population had increased by 3 million between 2000 and 2005 at a steady rate of 500,000 per year. This gain was part of a monotonic growth trajectory spanning from 29 million in 1980 to 49 million in 2008. During the same time Uganda increased from 12 to 31 million, and Sub-Saharan Africa as a whole doubled from 400 to 800 million, despite high prevalence HIV. We deduce from this demographic evidence that HIV is not a new killer virus. Based on a review of the known toxicities of antiretroviral drugs we like to draw the attention of scientists, who work in basic and clinical medical fields, including embryologists, to the need of rethinking the risk-and-benefit balance of antiretroviral drugs for pregnant women, newborn babies and all others who carry antibodies against HIV.

Abstract
The most frequent pathology of the lower lip is the neoplastic pathology and squamous cell carcinoma is the most clinically diagnosed. Wide excision is the correct surgical approach but it may cause severe morpho-functional and aesthetic damages. At the Plastic and Reconstructive Department of Policlinico Umberto I, " Sapienza" University of Rome, from 2005 to 2008 36 patients were treated, 19 only by surgical excision (Group I) and 17 by Johanson's technique (Group II). Follow-up was at 6 and 12 months to evaluate the morpho-functional outcome, the asymmetry and the healing. Moreover a questionnaire of 9 items was proposed to patients to evaluate functional and aesthetic results. Data showed that Johansons' s flap achieves the same results of the complete surgical excision but with better morpho-functional and aesthetic outcomes, greater satisfaction and same staying in hospital for patients.

Abstract
The polycystic ovarian syndrome (PCOS) includes a wide spectrum of clinical symptoms and signs. Three different diagnostic classifications have been proposed to define this disease. The first one, published in 1990, known as the "NIH criteria" requires the simultaneous presence of hyperandrogenism and menstrual dysfunction in order to diagnose PCOS. Later on, in 2003, an expert panel met in Rotterdam and added to the previous criteria the presence of polycystic ovarian morphology detected by transvaginal ultrasonography. The later classification broadened the spectrum of PCOS and also included women with oligomenorrhea and PCO without hyperandrogenism or hyperandrogenism and PCO without menstrual dysfunction. Finally, the Androgen Excess Society, published in 2006 new diagnostic criteria which required the presence of clinical or biochemical hyperandrogenism, with either PCO or menstrual dysfunction to diagnose PCOS. This review focuses on the diagnostic techniques and methods of treatment for PCOS patients. Special attention is given to the role of insulin resistance and the potential utility of insulin sensitizers in management of the syndrome. The benefit and utmost importance of lifestyle modification for the long-term health of these women is stressed as well. It is hoped that some clarity in this regard will allow more women to not only be diagnosed and managed properly for their presenting symptoms (hirsutism, irregular menses, etc.), but also to be educated and managed for the continuing health risk of insulin resistance throughout their lives.

Abstract
Phlebostatic sore of the lower limbs is a typical chronic venous insufficiency complication and is still a widely controversial issue in its treatment. The common therapies, in fact, are not yet standardized and they not show complete efficacy. Since 2005 to 2007 a multicentric clinical trial was conducted at the Plastic and Reconstructive Surgery of "Sapienza" University of Rome and at the Plastic and Reconstructive Surgery Department, University of Perugia, in order to evaluate the efficacy of the Idrastin lymph-draining cream in patients with phlebostatic sores of the lower limbs. This study enrolled on 80 patients, split into 2 homogeneous groups of 40 patients: group A was treated by only elastocompressive therapy, group B by elastocompressive therapy and Idrastin. Multicentric analysis has considered the following parameters: local pain, perilesional flogosis , granulation tissue, perilesional tissue tropism healing time. In the group B results highlighted: reduction of the local pain, stopped in 72 hours; flogosis decrease disappeared in one week; tissue granulation growth in one week; lesion healing in 4 weeks. These results pointed out statistically significance of the variables considered. In our opinion Idrastin compounds such as phytoessence of hops and Hedera helix, had contributed to analgesia; Aesculus hippocastanum, and Vitis vinifera and Ruscus aculeatus phytoessence showed anti-flogistic action; allantoin and Centella asiatica and jaluronic acid aided to sore healing. Idrastin gives an effective support to the treatment of the phlebostatic sores warrants a faster and more effective healing process, than to the wounds treated by only the elastocompressive therapy.

Abstract
Breast cancer represents the most prevalent malignancies in women and bone is the first site of metastasis in 26-50% of cases. Usually metastasis involve limbs in 16%. We present a rare case of 47-year-old woman, who underwent to monolateral mastectomy for lobular cancer. After 8 years from surgery, she presented pain, swelling and functional limitations, gradually increasing, to the left big toe. X-rays and MRI showed a lucent area of bone destruction on the shaft of the distal phalanx of the left big toe. Surgical biopsy on the excised bone assessed for breast cancer metastasis.

Abstract
Cadmium, a highly persistent heavy metal, has been categorized as a human carcinogen. Even though it is known that cadmium acts as estrogens in breast cancer cells, several studies failed to demonstrate whether cadmium is a causal factor for breast cancer. The lack of a strong association between cadmium and breast cancer could be found in the antiangiogenic properties of this heavy metal, which might counteract its carcinogenic properties in the progression of breast cancer. In this study, we exposed estrogen-responsive breast cancer cells to subtoxic levels of cadmium, and we evaluated their angiogenic potential using the chick embryo chorioallantoic membrane assay. Exposure of breast cancer cells to subtoxic levels of cadmium significantly inhibited the angiogenic potential of the breast cancer cell line, suggesting the possibility that cadmium might negatively regulate the production of proangiogenic factors in breast cancer cells. Our results suggest that cadmium might exert a paradoxical effect in breast cancer: on the one hand, it could promote carcinogenesis, and, on the other hand, it could delay the onset of tumors by inhibiting breast cancer cell-induced angiogenesis.

Abstract
Didactic dissection of the human body is still considered the best tool to teach and learn anatomy. Although the risk of being infected with pathogens during dissection has dramatically decreased, fear of infection is still widespread among medical students and health care professionals. The fear of contracting AIDS at the dissection table is of particular relevance because of the emotional implications accompanying the syndrome. In this study we analyze the actual risks of contracting AIDS during dissection in Italy by evaluating health policies and proportions of the epidemic. According to the Italian Ministry of Health, HIV infection and AIDS are not to be considered relevant threats to public health from the epidemiological point of view, and it is estimated that 99.7% of health care workers, who are exposed to HIV, will not be infected. In fact, there is only one well-documented case of an autopsy acquired HIV infection that happened in 1992 the United States. Furthermore, HIV infection is not necessarily associated with AIDS, and most HIV-positive subjects do not develop AIDS, provided that they do not assume toxic drugs or engage in risky behaviours. Conversely, according to the Ministry, AIDS can occur in the absence of signs of HIV infection. Taken together these considerations should help rationalizing the fear of contracting AIDS at the dissection table. The dissection hall can still be a dangerous place and the adoption of safe working practices and awareness of potential risks are mandatory; HIV serophobia, however, is unjustified.

Abstract
The effects of Friend erythroleukemia cells on angiogenesis were studied in chick embryo chorioallantoic membrane assay and in human umbilical vein endothelial cells. In chorioallantoic membrane assay, the conditioned medium of Friend cells stimulated in vivo angiogenesis to an extent comparable to that observed with Prostaglandin El, used as positive control. Prostaglandin El added to conditioned medium of Friend cells did not further increase angiogenesis. Conditioned medium of Friend erythroleukemia cells also stimulated proliferation of human umbilical vein endothelial cells to an extent comparable to that observed with fetal bovine serum, used as positive control. Conditioned medium and fetal bovine serum together did not affect human umbilical vein endothelial cells proliferation, as compared to that observed when tested separately. These results seem to indicate that Friend erythroleukemia cells produce and secrete factors stimulating angiogenesis. These findings extend and confirm the hypothesis that successful angiogenesis is necessary for development of leukemias.

Abstract
Cardiovascular disease caused by accelerated atherosclerosis is the major determinant of morbidity and mortality in chronic kidney disease patients. Vitamin D and its analogs provide survival benefit for hemodialysis (HD) patients. Vitamin D exerts its effects through the vitamin D receptor (VDR) that is coded for by a gene showing several polymorphisms that, in turn, are associated with a variety of diseases and differential responses to vitamin D. In this study, we evaluated the association between 4 VDR polymorphisms (ie, those identified by the restriction enzymes BsmI, ApaI, TaqI, and FokI) and iron indices (serum iron, transferrin, transferrin saturation, and ferritin) in 88 hemodialysis patients routinely treated with vitamin D. The absence or presence of the BsmI, ApaI, TaqI, and FokI restriction sites were denominated B and b, A and a, T and t, F and f, respectively. Our results show that in HD patients with transferrin saturation <20%, the F allele was more frequent than in HD patients with transferrin saturation >20% (P = .03). This relationship may provide a link between VDR alleles and iron and nutritional markers, which are highly predictive variables of cardiovascular morbidity and mortality in hemodialysis patients.

Abstract
Experiments were performed on the chorio-allantoic membrane (CAM) of the chick to evaluate the effects of bombesin (BN) on vascular neoformation. In morphometrical assays, 10(-13)-10(-4) M BN promoted dose-dependent vascular development. Newly formed vessels converged toward the BN release site in a spoked wheel arrangement, suggesting a diffusion gradient mechanism. Structural and ultrastructural analysis of CAM specimens collected near the BN release site showed that both vasculogenetic and angiogenetic processes cooperated in vascular neoformation that involved committed cells from the mesenchyme (angioblasts) as well as endothelial cells. No pattern of vascular development was detected away from the BN release site. Findings from the present study emphasize the role of BN in vascular net development of respiratory organs.
