Physiological responses to repeated endotoxin challenge are selectively affected by recombinant bovine somatotropin administration to calves.

The study determined 1) whether the pretreatment of calves with recombinant bovine somatotropin (bST, sometribove) would alter the change in packed cell volume (PCV), rectal temperature (RT), and the plasma concentrations of Ca2+, Fe2+, glucose (G), urea N (PUN), nonesterified free fatty acids (NEFA), albumin (ALB), and blood cell populations after endotoxin challenge (EC) and 2) whether the natural development of physiologic tolerance to repeated EC was affected by bST. Twelve steer beef calves were assigned to either control (-bST) or +bST treatment in equal numbers. Calves were injected intramuscularly with either HCO3(-)-buffered saline or bST (0.1 mg/kg) daily for 5 d. On Day 6, the first EC was administered (Escherichia coli, 055:B5, 0.2 microgram/kg, intravenous bolus in pyrogen-free saline). Saline or bST injections were continued from Day 7 up to the repeat of EC on Day 11. RT and PCV were measured hourly through 12 and 6 hr, respectively. Jugular blood was obtained at 0, +1, 2, 3, 4, 6, 8, 12, and 24 hr relative to each EC. bST had no effect on the increase in RT, the hyperglycemic phase of the G response, the biphasic change in Fe2+, or increases in NEFA and PUN. PCV increased after each EC only in -bST. The mean decrease in G during the hypoglycemic phase was less in +bST. Hypocalcemic responses were significantly less in +bST. ALB concentrations decreased after each challenge; the response was unaffected by bST. CD2+, CD4+, and CD8+ T-lymphocyte populations were unaffected by bST and EC. Overall, the magnitude of change in all plasma variables was less after the second EC compared with the first, either in terms of magnitude or duration. The data suggest that the treatment of calves with bST diminishes the magnitude of hypoglycemic, hypocalcemic, and PCV changes after EC and does not compromise fever response, changes in blood cell populations, or tolerance to repeated EC.

Glycosylation accelerates albumin degradation in normal and diabetic dogs.

Nonenzymatic glycosylation of albumin was associated with an increased catabolic rate and decreased protein half-life in both normal and diabetic animals. The fractional catabolic rate of glycosylated albumin was increased significantly over albumin, from 0.100 +/- 0.004/day to 0.131 +/- 0.007/day in normal animals and from 0.104 +/- 0.004/day to 0.138 +/- 0.007/day when these animals were made diabetic with alloxan. The half-lives of Alb and GlyAlb in normal dogs were 6.81 +/- 0.12 days and 4.97 +/- 0.21 days, respectively. In diabetic animals, the half-lives of Alb and GlyAlb were 7.48 +/- 0.21 and 5.21 +/- 0.24 days, respectively. The increased catabolism of GlyAlb may reflect chronic increased extravasation of glycosylated plasma proteins, which are known to be increased in diabetes, into the microvascular wall.

Measurement of serum glycosylated proteins and glycosylated low density lipoprotein fraction in diabetes mellitus.

A simple method was developed for estimating serum glycosylated protein levels using gel filtration with Bio-Gel P6 by determining the protein and sugar content in the void volume fraction. The glycosylated protein levels (GSP) correlated well with fasting blood sugar levels and glycosylated albumin level (G-ALB) determined by affinity chromatography with Blue Sepharose CL6B. The glycosylation level of heparin-citrate precipitable fraction of serum which predominantly contained low density lipoprotein (G-LDL) also correlated well with GSP and LDL-cholesterol levels. Significantly different values were obtained for GSP, G-ALB, and G-LDL between normals and diabetics.

Effect of surface-adsorbed proteins and phosphorylation inhibitor AG18 on intracellular protein expression in adherent macrophages.

Macrophages are believed to play an important role in the host inflammatory response to implanted biomaterials. However, the mechanism of macrophage adhesion to protein-adsorbed substrates and the subsequent activation and inflammation is unresolved. Previously the effect of various surface-adsorbed proteins and increasing concentrations of phosphorylation inhibitor AG18 on intracellular protein expression levels in adherent human monocytic cell line U937 was identified using SDS-PAGE and densitometry. The protein ligands and AG18 concentrations up or down regulated the expression of a set of proteins ranging from approximately 200 to approximately 23 kDa. In the present work, HPLC coupled tandem mass spectroscopy (LC/MS) was used to identify proteins in these bands. We hypothesized that key proteins in macrophage adhesion and activation could be identified by observing protein expression resulting from various surface-adsorbed ligands and AG18 concentrations. Increasing concentrations of AG18 down or up regulate protein expression in adherent U937 on PBS-adsorbed TCPS at approximately 52, approximately 42 and approximately 23 kDa. AG18 concentrations had no effect on cells on albumin (Alb)-adsorbed surfaces but regulated different protein expression in adherent U937 on fibronectin (FN)-adsorbed TCPS at 40 and 80 microm AG18. Both Alb and FN regulate distinct sets of proteins in adherent cells as surface-adsorbed ligands. Based on the data from LC/MS, both surface associated ligand and increasing concentrations of AG18 modulate shifts in intracellular signaling.

Burn patient characteristics and outcomes following resuscitation with albumin.

BACKGROUND: Use of colloids in acute burn resuscitation may reduce fluid requirements, but effect on mortality is unknown. We hypothesized that patients who received albumin would have similar mortality to patients who did not receive albumin. METHODS: We performed a case-controlled study of inpatients who sustained burns of > or =20% total body surface area (TBSA). Patients who received albumin during resuscitation because of increased fluid requirements (ALB) were compared to a cohort of patients matched for age and TBSA who did not receive albumin (CON). RESULTS: Patients with inhalation injury were significantly more likely to receive albumin (OR 4.89, 95% CI 2.58-9.30). ALB patients had significantly higher mean initial lactate (3.64 versus 2.29, p=0.01), longer mean time to resuscitation (52.8 h versus 36.3 h; p=0.001), and higher resuscitation volume (9.4 mL/kg/%TBSA versus 6.4 mL/kg/%TBSA for CON). Mortality was not significantly different between the two groups (OR 1.90, 95% CI 0.85-4.22). Albumin was protective in a multivariate model of mortality (OR 0.27, 95% CI 0.07-0.97). CONCLUSIONS: Despite more severe systemic dysfunction, burn patients who received albumin did not suffer increased mortality. A novel finding is the decreased likelihood of mortality associated with the administration of albumin during burn resuscitation.

Blood biochemistry reveals malnutrition in black-necked swans (Cygnus melanocoryphus) living in a conservation priority area.

The application of clinical biochemical techniques to determine the products of intermediary metabolism has proved to be a reliable approach for the study of the physiological state of animals in nature. More specifically, the determination of plasma metabolites, such as glucose, total proteins (PRO), albumin (ALB), globulins (GL), urea, uric acid, triglycerides (TG) and beta-hydroxy-butyrate (BHB), and plasma enzymes such as creatine kinase (CK) and aspartate aminotransferase (AST) in wild animals is a valuable possibility for a non-destructive assessment of health in endangered populations. Since August 2004 to January 2005, we conducted a temporal study in a conservation priority site, the "Carlos Anwandter Nature Sanctuary" to determine blood biochemistry of a wild population of black-necked swans (Cygnus melanocoryphus). This population was experiencing a drastic reduction, according to the actual knowledge about yearly fluctuations in numbers and breeding pairs. In six months, we periodically sampled about 12 swans (a total of 122 individuals), which exhibited a reduction near 30% in body mass (body mass corrected by total length). Our results showed reductions in most plasma biochemical parameters (glucose, PRO, ALB, uric acid, TG) and increase in BHB, which taken together indicated signs of chronic malnutrition. Also, the increase in AST and CK that we found, together with additional evidences of sub-lethal hepatic damage (in dead individuals), and iron pollution in aquatic plants and water confirmed that water pollution was the ultimate cause of this population reduction.

A novel ELISA system for selective measurement of human adiponectin multimers by using proteases.

BACKGROUND: Adiponectin, an antiatherogenic adipocyte-derived protein exists in human blood as multiple isoforms--trimeric low molecular weight (LMW), albumin-binding LMW (Alb-LMW), hexameric middle molecular weight (MMW), and high molecular weight (HMW) forms. We developed a novel ELISA system to detect total human adiponectin and the selective level of each adiponectin multimer for investigating the distribution of these levels in human blood. METHODS: Two monoclonal antibodies that were raised against human adiponectin were used to construct a sandwich ELISA to measure adiponectin levels. Adiponectin multimers were selectively measured after sample pretreatment with two proteases that specifically digested the trimeric forms or both the hexameric and trimeric forms. RESULTS: The ELISA had a dynamic range of 0.075-4.8 ng/ml. Intraassay variations (CV) were 5.3% (total adiponectin), 4.1% (MMW+HMW), and 3.3% (HMW). Comparison of the results of ELISA and quantitative western blot analysis of multimeric adiponectin in serum samples revealed good correlation (LMW+Alb-LMW, r=0.873; MMW, r=0.907; HMW, r=0.950). Each of the three forms of adiponectin multimer levels closely correlated with total adiponectin levels in healthy subjects. CONCLUSIONS: This ELISA system can be used to further investigate the physiological roles of human adiponectin multimers.

The role of inheritance and environment in predisposition to vascular disease in people of African descent.

OBJECTIVES: This study sought to compare vascular reactivity and carotid intima media thickness (CIMT) between Afro-Caribbean people in the United Kingdom (UK) and the West Indies and Afro-Caribbean and Caucasian people in the UK. BACKGROUND: Attenuated vascular reactivity and increased CIMT in black patients is seen as evidence for predisposition to vascular disease, but no comparisons exist between Afro-Caribbean people in different settings, which can provide insight into non-inherited determinants of increased ethnic susceptibility. METHODS: A representative community sample of 81 healthy Afro-Caribbean people and 101 Caucasian people in the UK was compared with 197 matched Afro-Caribbean people in Jamaica. Small vessel reactivity was assessed by measuring the absolute change from baseline in the reflection index (RI) of the digital volume pulse during intravenous infusion of albuterol (5 microg/min, DeltaRI(ALB)) and glyceryl trinitrate (5 microg/min, DeltaRI(GTN)). The CIMT was measured ultrasonographically in the distal 1 cm of the common carotid artery. RESULTS: Mean DeltaRI(ALB) was 4.2 percentage points (95% confidence interval [CI], 2.3 to 6.1, p < 0.001) lower in UK Afro-Caribbean people compared with Jamaican Afro-Caribbean people and 2.6 percentage points (95% CI, 0.4 to 4.7, p = 0.02) lower compared with Caucasian people, after adjusting for vascular risk profile. Adjusted mean CIMT of UK Afro-Caribbean people was 0.13 mm (95% CI, 0.08 to 0.17, p < 0.001) greater compared with Jamaican Afro-Caribbean people and 0.05 mm (95% CI, 0.01 to 0.10, p = 0.02) greater compared with Caucasian people. CONCLUSIONS: Healthy UK Afro-Caribbean people have greater and Jamaican Afro-Caribbean people have less impairment of vascular reactivity and intima media thickness compared with UK Caucasian people, suggesting that potentially modifiable environmental interactions may contribute to excess vascular disease in Afro-Caribbean people.

Growth and differentiation of colony-forming human hepatocytes in vitro.

BACKGROUND/AIMS: Parenchymal hepatocytes (PHs) of rat contain colony-forming parenchymal hepatocytes (CF-PHs) as a small fraction. We aimed to demonstrate the presence of CF-PHs in humans and characterize them with respect to growth and differentiation potential. METHODS: Human PHs were co-cultured with Swiss 3T3 cells in the medium containing human serum, EGF, nicontinamide, and ascorbic acid 2-phosphate. To examine differentiation potential hepatocytes were cultured on gels of Matrigel Matrix. RESULTS: Few PHs formed colonies, the colony-forming efficiency being as low as 0.01-0.09%. The CF-PHs could be subcultured up to 7 passages. They showed a liver epithelial cell-like morphology, and immunocytochemically positive for albumin (ALB), cytokeratin (CK) 7, 8, 18, and 19 in a pre- and early phase-confluence, whereas they showed a typical differentiated hepatocyte-like morphology, and positive for alpha(1)-antitrypsin, but negative for CK7 and 19 in condensed regions at confluence. The CF-PHs at late confluence expressed mRNAs of ALB, HNF4, and isoforms of cytochrome P450 at low levels. However, when cultured on Matrigel, these cells expressed them at high levels comparable to those of original PHs. CONCLUSIONS: We concluded that the human liver contains highly replicative hepatic progenitor-like cells as a minute population that retain a normal differentiation potential.

Screening of copy number polymorphisms in human beta-defensin genes using modified real-time quantitative PCR.

Defensins are cationic antimicrobial peptides, which play an important role in host immune defense to some infectious diseases as well as immune disease and skin disease. Recent studies identified that the genes coding for human beta-defensin 2 (DEFB4), human beta-defensin 3 (DEFB103) and human beta-defensin 4 (DEFB104) showed variation in copy numbers. This variation may have an impact on gene expression levels. Here, we have demonstrated a real-time PCR-based method to measure beta-defensin gene copy number. Using this relative real-time quantitative PCR, we developed a new rapid and reliable approach, which involves amplification of the target locus (DEFB4 or DEFB103 or DEFB104) and the single-copy reference locus (human serum albumin, ALB) in a single PCR reaction. A calibrator was prepared by recombining one copy of the target gene and one copy of the reference gene into a plasmid. After correcting the PCR amplification efficiency, which differed between the defensin gene and ALB gene, and normalization by the calibrator, the ratio of the copy number of the target gene to that of the reference gene in an unknown sample was determined. This normalized ratio directly related to the gene copy number. The assay was validated using previously genotyped samples, which demonstrated high accuracy and reliability of the method. Furthermore, this method was used to screen the copy number variations of these three beta-defensin genes in healthy blood donors. This method proved to be a reliable and fast tool to genotype gene copy number variations in projects associating genomic variations with gene expression or with population phenotypes in epidemiologic studies.

Neuron-specific enolase in patients with neurocysticercosis.

BACKGROUND: Neurocysticercosis (NC) is the most frequent parasitic disease of the human nervous system. Its clinical manifestations are varied and depend on the number and location of cysts, as well as the host immune response. Symptoms in NC usually occur when cysts enter into a degenerative phase associated with perilesional inflammation. We speculate that neuron-specific enolase (NSE)--a marker of neuronal injury--could be elevated in patients with degenerating cysts comparing to those with viable cysts. METHODS: We examined serum NSE (sNSE) and cerebrospinal fluid (CSF) NSE (cNSE) levels in 25 patients with NC: 14 patients with degenerative cysts (D), 8 patients with viable cysts (V) and 3 patients with inactive cysts. Samples of eight normal controls (C) were also obtained. Determination of albumin was performed in serum and CSF samples, and the CSF/serum albumin ratio (albumin quotient, Q(alb)) was used to estimate the blood-brain barrier permeability. RESULTS: All patients, with the exception of one case, had five or less cysts. Comparisons between V, D and C groups did not demonstrate significant differences of cNSE, Q(alb) and sNSE levels. Further, there were no significant differences of cNSE and sNSE levels between patients with or without intracranial hypertension (ICH). CONCLUSIONS: These findings suggest that the inflammatory response associated with a relatively small number of degenerating cysts does not provoke significant neuronal damage. Further studies considering patients with a larger number of cysts will be required to assess if there is evidence of neuronal damage in such more severe cases.

Serum prealbumin and albumin concentrations do not reflect nutritional state in children with cerebral palsy.

Serum prealbumin concentration (PALB) and albumin concentration (ALB) were evaluated as markers of undernutrition in 107 children with cerebral palsy (CP) age 2 to 18 years. PALB and ALB were rarely below the normal reference ranges and showed little to no correlation with anthropometric measures (eg, skinfolds, midarm fat area), growth (height), severity of CP (eg, feeding dysfunction, motor impairment), or general health.

Aplysia seductin is a water-borne protein pheromone that acts in concert with attractin to stimulate mate attraction.

Mate attraction in Aplysia involves the long-distance water-borne protein pheromones attractin, enticin, and temptin which are released during egg-laying. Other water-borne pheromones are predicted to act in concert with attractin, enticin, and temptin, but their identities were unknown. We recently identified a highly expressed Aplysia californica albumen gland gene (Alb-23) that encoded a novel protein by differential library screening of an albumen gland cDNA library. To determine whether Alb-23 ('seductin') was a water-borne pheromone, we employed Western blot analysis, purification and expression of albumen gland proteins, immunolocalization studies, pheromone secretion assays, comparative genomics, and behavioral bioassays. Immunoreactive seductin was detected in eluates of egg cordons, indicating that seductin was secreted onto the cordon during egg laying. Aplysia brasiliana seductin was 94% identical to its A.californica homolog. In T-maze attraction assays, the combination of attractin and seductin was significantly attractive to potential mates, whereas either protein alone was not. Data from this and previous studies support the hypothesis that seductin is a water-borne protein pheromone that acts in concert with attractin, enticin, and temptin to attract Aplysia to form and maintain mating aggregations.

Two families of antimicrobial peptides with multiple functions from skin of rufous-spotted torrent frog, Amolops loloensis.

There are around 27 species of Amolops amphibian distributed in South-east of Asia. Seven antimicrobial peptides (AMPs) belonging to two different families were purified from skin of rufous-spotted torrent frog, Amolops loloensis, and designated brevinins-ALa, b, c, and d, and temporins-ALa, b, and c. The brevinins-AL family which is structurally related to brevinins-1 from skin secretions of the European frog, Rana brevipoda, is composed of 24 amino acids and has an intra-disulfide bridge at the C-terminus. The temporins-AL family, composed of 13 or 16 amino acid residues, is related with temporins from the skin secretions of R. temporaria. The findings of this study will facilitate the solutions to the taxonomic questions of the ranid genus Amolops and Staurois. In the work of this paper, both brevinins-ALb and temporin-Ma induced mast cell degranulation and histamine release, and had cytotoxic activity toward solid tumor cell line HepG(2). Brevinins-ALb also exerted strong hemolytic activity while temporin-Ma had no such activity.

Phosphorylated cyclic AMP response element binding protein expression induced in the periaqueductal gray by predator stress: its relationship to the stress experience, behavior and limbic neural plasticity.

Electrophysiological studies in cats and recently in rats implicate neuroplasticity in the periaqueductal gray (PAG) and its afferents in stressor-induced increases in fearful behavior and anxiety-like behavior (ALB). Such increases may model aspects of affective changes following traumatic stress in humans. The present study explored the role of neuroplasticity in PAG and its connection with the central nucleus of the amygdala (ACE) in male rodent anxiety-like response to predator stress. In the first of two studies, the effects of predator stress on the induction of phosphorylated cyclic AMP response element binding protein (pCREB) were investigated. pCREB expression in the PAG and ventromedial hypothalamus (VMH) was examined immunohistochemically. Predator stress increased the degree of pCREB expression in PAG cells (measured densitometrically) but did not increase the number of cells expressing pCREB (measured stereologically). Moreover, predator stress-specific increase in pCREB-like immunoreactivity (lir) was restricted to the right lateral column of the PAG. In addition, pCREB lir in the right lateral column likely reflects aspects of the stress experience because the stressor (cat behavior) and the response to the stressor (rat defensive behavior) are highly predictive of degree of pCREB expression. There was no effect of predator stress on pCREB lir in the VMH. Because pCREB expression has been associated with long-lasting potentiation (LLP) of neural transmission, we examined the effects of predator stress on transmission in the ACE-PAG pathway in a second study. Predator stress elevated evoked potential measures of ACE-PAG transmission in the right hemisphere but not in the left hemisphere 11-12 days after predator stress. This finding is consistent with the longer-lived effects of pharmacological stress on amygdalo-PAG transmission in the right hemisphere but not in the left hemisphere in cats. Of interest is the fact that the same aspects of the stressor experience and reaction to it, which are predictive of the degree of pCREB expression, are also highly predictive of the degree of potentiation of measures of ACE-PAG transmission. Behavioral analyses revealed that the most consistent effects of predator stress are on behavior in the plus maze (open arm exploration and risk assessment) and on startle. In addition, covariance analysis suggests that ACE-PAG potentiation mediates some but not all of the changes in ALB produced by predator stress. Because pCREB expression may be a precursor to neuroplastic changes in certain forms of memory and LLP, the present findings complement studies in the cat, showing that neuroplastic changes in the PAG underlie changes in affect following stress. Furthermore, these findings suggest that neuroplastic changes in PAG may be important mediators of predator stress-induced changes in affective behavior in rodents. Finally, consistent with cat and human studies, the right hemisphere appears particularly important in long-term response to stress.

Pushing the envelope in renal preservation; improved results with novel perfusate modifications for pulsatile machine perfusion of cadaver kidneys.

INTRODUCTION: Novel preservation techniques may diminish ischemia/reperfusion (I/R) injury. Our preservation laboratory has modified Belzer MPS for machine perfusion (MP) with prostaglandin E1 (PGE 1), nitroglycerin (NTG), and polyethylene glycol-superoxide dismutase (PEG-SOD) to attenuate I/R injury. We reviewed our recent experience using this novel formulation (NF) compared with standard perfusates. RESULTS: Between January 1998 and March 2000, 1060 consecutive kidneys were preserved in our laboratory. One hundred forty-eight kidneys (14%) were discarded. Fifty-eight percent of kidneys during this time period underwent MP (n = 532). En bloc kidney pairs were randomly assigned to pulsatile MP using Waters RM3 or MOX-100 perfusion systems using 1 of 3 perfusates; NF (NF; n = 119), Belzer MPS (MPS; n = 201), or Belzer II albumin gluconate (ALB; n = 212) Significant improvements in delayed graft function (DGF) rate were seen with NF versus other perfusates (8% vs 14% vs 19%, respectively; P =.03). At 6 months, graft survival was significantly improved with NF compared with MPS and ALB (96% vs 90% vs 87%, respectively; P =.03). NF also produced a significantly higher percentage of recipients with a serum creatinine level < or = 1.5 mg/dL. CONCLUSIONS: Novel modifications of standard MP perfusate improved outcomes after renal transplantation. Preservation-based interventions targeted to ameliorate I/R injury can improve outcomes and may allow expansion of the donor pool.

Differentiation of hematopoietic stem cells into hepatocytes in liver fibrosis in rats.

It has been reported that hematopoietic stem cells (HSC) can differentiate into hepatocytes in the normal liver and in some pathologic environments. The aim of this study was to investigate whether HSC can differentiate into hepatocytes in cases of established liver fibrosis. Rat liver fibrosis was induced by subcutaneous injection of tetrachloride (CCl4). Thy+ CD3- CD45RA- HSC in bone marrow cells, which had been enriched by fluorescence-activated cell sorting (FACS), were labeled with PKH26-GL, and autologously transplanted into CCl4-treated rats. The expressions of albumin (Alb), cytokeratin 8 (CK8), and alpha-smooth muscle actin (SMA) were determined by immunofluorescence methods. The PKH26-GL labeled Thy+ CD3- CD45RA- HSC expressed the hepatocyte-specific markers Alb and CK8, but did not express alpha-SMA in liver fibrosis. Thy+ CD3- CD45RA- HSC differentiated into hepatocytes, but not into hepatic stellate cells. In conclusion, autologous stem cell transplantation may be helpful to treat hepatic fibrosis.

Biochemical and histopathological findings of N-butyl-2-cyanoacrylate in oral surgery: an experimental study.

OBJECTIVES: The increasing use of cyanoacrylates in dentistry, particularly as an adhesive and sealing glue, has raised concerns regarding its potential toxicity in humans. Several different forms of these compounds including methyl- (MCA), ethyl- (ECA), isobutyl-, isohexyl-, and octyl CA have been developed to eliminate tissue toxicity. N-butyl-2-cyanoacrylate is becoming an increasingly popular method for wound closure under low tension. Despite their increasing use, pharmacologic effects of these substances on liver and kidney functions are not widely known. The objective of the present study was to investigate possible immediate and long-term systemic effects of N-butyl-2-cyanoacrylate in oral surgery. STUDY DESIGN: Ten male Wistar rats weighing 220 to 270 g were used in the study. Straight incisions were made to the buccal mucosa of the animals. N-butyl-2-cyanoacrylate adhesive (Indermil) was applied and wounds were closed primarily. Blood specimens were taken periodically from the vena cava of the animals before the surgical procedure and 2, 14, 21, and 65 days after the surgical procedure. The blood specimens of those taken before the application of the adhesive were defined as the control group; blood specimens that were taken 2, 14, 21, and 65 days from the application were defined as study group. The stored plasma samples were analyzed for blood urea nitrogen (BUN), creatinine (CRE), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBI), total protein (TP), albumin (ALB), and amylase (AML). In addition to biochemical parameters, histopathological examination was performed. Blood parameter values of the control and study groups were statistically compared with the Duncan test (P < .05). RESULTS: There were no significant differences in the values of BUN, CRE, ALT, AST, TBI, TP, ALB, and AML between the control and at 2, 14, 21, and 65 days. CONCLUSION: The present study shows that N-butyl-2-cyanoacrylate is a suitable adhesive applicable in oral surgery.
