Abstract
Porphyromonas gulae, Tannerella forsythia and Campylobacter rectus are considered dominant periodontal pathogens in dogs. Recently, quantitative real-time PCR (qRT-PCR) methods have been used for absolute quantitative determination of oral bacterial counts. The purpose of the present study was to establish a standardized qRT-PCR procedure to quantify bacterial counts of the three target periodontal bacteria (P. gulae, T. forsythia and C. rectus). Copy numbers of the three target periodontal bacteria were evaluated in 26 healthy dogs. Then, changes in bacterial counts of the three target periodontal bacteria were evaluated for 24 weeks in 7 healthy dogs after periodontal scaling. Analytical evaluation of each self-designed primer indicated acceptable analytical imprecision. All 26 healthy dogs were found to be positive for P. gulae, T. forsythia and C. rectus. Median total bacterial counts (copies/ng) of each target genes were 385.612 for P. gulae, 25.109 for T. forsythia and 5.771 for C. rectus. Significant differences were observed between the copy numbers of the three target periodontal bacteria. Periodontal scaling reduced median copy numbers of the three target periodontal bacteria in 7 healthy dogs. However, after periodontal scaling, copy numbers of all three periodontal bacteria significantly increased over time (p<0.05, Kruskal-Wallis test) (24 weeks). In conclusion, our results demonstrated that qRT-PCR can accurately measure periodontal bacteria in dogs. Furthermore, the present study has revealed that qRT-PCR method can be considered as a new objective evaluation system for canine periodontal disease.

Abstract
This study evaluated the accuracy and reproducibility of a human portable blood glucose meter (PBGM) for canine and feline whole blood. Reference plasma glucose values (RPGV) were concurrently measured using glucose oxidation methods. Fifteen healthy dogs and 6 healthy cats were used for blood sampling. Blood glucose concentrations and hematocrits were adjusted using pooled blood samples for our targeted values. A positive correlation between the PBGM and RPGV was found for both dogs (y = 0.877, x = -24.38, r = 0.9982, n = 73) and cats (y = 1.048, x = -27.06, r = 0.9984, n = 69). Acceptable results were obtained in error grid analysis between PBGM and RPGV in both dogs and cats; 100% of these results were within zones A and B. Following ISO recommendations, a PBGM is considered accurate if 95% of the measurements are within ± 15 mg/dl of the RPGV when the glucose concentration is <100 mg/dl and within ±15% when it is ≥100 mg/dl; however, small numbers of samples were observed inside the acceptable limits for both dogs (11%, 8 of 73 dogs) and cats (39%, 27 of 69 cats). Blood samples with high hematocrits induced lower whole blood glucose values measured by the PBGM than RPGV under hypoglycemic, normoglycemic, and hyperglycemic conditions in both dogs and cats. Therefore, this device is not clinically useful in dogs and cats. New PBGMs which automatically compensate for the hematocrit should be developed in veterinary practice.

Abstract
Reduced expression in immortalized cells (REIC/Dkk-3), a member of the human Dickkopf (Dkk) family, is a growth suppressor in human and canine mammary tumours. Mammary gland tumours are common neoplasms with high malignancy in female cats. The purpose of this study was to clone the feline REIC/Dkk-3 homolog, investigate its expression in cell lines established from feline mammary gland tumours, and test its tumour suppressor function. Western blot analysis revealed that expression of the REIC/Dkk-3 protein was reduced in feline mammary carcinoma cell lines. Forced expression of REIC/Dkk-3 induced apoptosis in feline mammary tumour cell lines. These results demonstrate that REIC/Dkk-3 expression, which is downregulated in feline mammary tumour cell lines, results in the induction of apoptosis in these cells. Our findings suggest that feline REIC/Dkk-3 represents a potential molecular target for the development of therapies against feline mammary cancers.

Abstract
It is well known that furocumarins produce a photoaddition compound with DNA, RNA, and certain kinds of amino acids upon exposure to long-wave ultraviolet light (UVA). It is also well known that both psoralens and psoralen photoconjugated compounds are fluorescent. After 8-methoxypsoralen was administered systemically and subsequently activated by UVA exposure, the hair and the epidermis were taken and observed under a fluorescent light microscope. The fluorescent materials appeared to be able to trace the metabolic pathway of psoralen-conjugated compounds such as DNA, RNA, and certain kinds of amino acids. Large amounts of nuclear proteins appeared to be transformed from nuclear proteins into certain structural proteins in keratinocytes.

Abstract
BACKGROUND We developed a fibrinogen γ-chain (dodecapeptide HHLGGAKQAGDV [H12])-coated, ADP-encapsulated liposome (H12-[ADP]-liposome) that accumulates at bleeding sites via interaction with activated platelets via glycoprotein IIb-IIIa and augments platelet aggregation by releasing ADP. OBJECTIVE To evaluate the efficacy of H12-(ADP)-liposomes for treating liver hemorrhage in rabbits with acute thrombocytopenia. METHODS Thrombocytopenia (platelets < 50 000 μL(-1)) was induced in rabbits by repeated blood withdrawal (100 mL kg(-1) in total) and isovolemic transfusion of autologous washed red blood cells. H12-(ADP)-liposomes with platelet-poor plasma (PPP), platelet-rich plasma (PRP), PPP, ADP liposomes with PPP or H12-(PBS)-liposomes/PPP, were administered to the thrombocytopenic rabbits, and liver hemorrhage was induced by penetrating liver injury. RESULTS Administration of H12-(ADP)-liposomes and of PRP rescued all thrombocytopenic rabbits from liver hemorrhage as a result of potent hemostasis at the liver bleeding site, although rabbits receiving PPP or ADP liposomes showed 20% survival in the first 24 h. Administration of H12-(ADP)-liposomes and of PRP suppressed both bleeding volume and time from the site of liver injury. H12-(phosphate-buffered saline)-liposomes lacking ADP also improved rabbit survival after liver hemorrhage, although their hemostatic effect was weaker. In rabbits with severe thrombocytopenia (25 000 platelets μL(-1)), the hemostatic effects of H12-(ADP)-liposomes tended to be attenuated as compared with those of PRP treatment. Histologic examination revealed that H12-(ADP)-liposomes accumulated at the bleeding site in the liver. Notably, neither macrothombi nor microthrombi were detected in the lung, kidney or liver in rabbits treated with H12-(ADP)-liposomes. CONCLUSIONS H12-(ADP)-liposomes appear to be a safe and effective therapeutic tool for acute thrombocytopenic trauma patients with massive bleeding.

Abstract
This randomized trial investigated whether 5% sevoflurane potentiated neuromuscular blockade by vecuronium. General anaesthesia was induced with 5% sevoflurane in oxygen in 16 patients or with propofol in 16 patients. After loss of consciousness, vecuronium was administered to all participants at randomly assigned doses of 25, 30, 35 or 40 μg/kg. Neuromuscular blockade was assessed by use of acceleromyography to measure responses to train-of-four stimuli in the adductor pollicis and corrugator supercilii muscles. Maximum blockade was significantly more intense in the adductor pollicis among patients in the sevoflurane group than in the propofol group, whereas there was no significant between-group difference at the corrugator supercilii muscles. In both groups, maximum blockade at the corrugator supercilii was significantly less intense than that achieved at the adductor pollicis. In the dose–response analysis, the 50% and 95% effective doses were lower for sevoflurane than for propofol in both muscles, although this did not reach statistical significance. It is concluded that induction of general anaesthesia with sevoflurane might provide improved conditions for intubation and reduce airway problems.

Abstract
BACKGROUND Little information is available regarding the neuromuscular effects of sevoflurane in patients with myasthenia gravis (MG). We evaluated the neuromuscular effects of sevoflurane alone in patients with MG and in those with normal neuromuscular transmission. METHODS Sixteen patients with generalized type MG (MG group) and 12 otherwise healthy patients (control group) entered into this study. Anaesthesia was induced with propofol, fentanyl, and midazolam followed by nitrous oxide in oxygen. Neuromuscular monitoring was recorded from the adductor pollicis muscle using electromyography with train-of-four stimulation of the ulnar nerve. After a stabilization period, and before sevoflurane administration, baseline T4/T1 was obtained and MG patients were classified as non-fade MG group (baseline T4/T1 > or = 0.90) (n = 10) and fade MG group (baseline T4/T1 < 0.90) (n = 6). End-tidal sevoflurane concentration was kept constant at 1.7% for 30 min and doubled thereafter to 3.4% and maintained for a further 30 min. RESULTS Sevoflurane produced a concentration-dependent decrease in T1 and T4/T1 values. At 3.4% sevoflurane, T1 and T4/T1 decreased significantly from baseline values in all three groups. From baseline until the patient woke up from anaesthesia, the T4/T1 of the fade MG group was significantly lower than the other groups. At the end of anaesthesia, T4/T1 returned to values similar to the baseline in all three groups. CONCLUSIONS During sevoflurane anaesthesia, concentration-dependent inhibition of neuromuscular transmission was observed in MG and control patients. The inhibitory effects of sevoflurane were more prominent in MG patients with baseline T4/T1 <0.90.

Abstract
BACKGROUND AND OBJECTIVE Postoperative nausea and vomiting (PONV) after ophthalmic surgery under general anaesthesia remains a complex and perturbing complication associated with several factors. Little information is available regarding the risk factors for nausea and vomiting after vitrectomy in adults. In this study, we evaluated the potential risk factors for PONV after vitrectomy in adult patients. METHODS Univariate and multivariate analyses of clinical factors associated with PONV were undertaken in a retrospective case-control series of 247 adult patients undergoing vitrectomy under general anaesthesia. We examined PONV for the first 48 h. Factors examined were age, body mass index (BMI), smoking status, H2-blocker as premedication, type of general anaesthesia (sevoflurane and fentanyl or total intravenous (i.v.) anaesthesia with propofol and fentanyl), duration of surgery, and intraoperative fentanyl dose. RESULTS Fifty-nine patients (24%) reported one or more episodes of PONV during the study period. Female gender (P < 0.01), lower BMI (P < 0.01) and general anaesthesia with inhalational anaesthetics (P < 0.01) were significantly related to nausea during the first 2 h postoperatively. Female gender (P < 0.01) was significantly related to nausea and vomiting throughout the study period. Other factors, including smoking status, did not alter the risk for nausea and/or vomiting. CONCLUSIONS We conclude that female gender, lower BMI and inhalation anaesthesia are the main risk factors for PONV after vitrectomy in adults. Smoking status did not reduce the incidence of PONV in our patients.

Abstract
BACKGROUND AND OBJECTIVE The optimal depth of insertion of left-sided double-lumen endobronchial tubes is strongly correlated with body height in average-sized adults. However, this relationship has not been studied in below average-sized adult patients. We investigated whether or not there is a clinically useful relationship in below average-sized adult patients. METHODS One hundred and ninety six consecutive adult patients undergoing thoracic surgery under one-lung anaesthesia (body height < or = 155 cm) were included in this study. Left-sided double-lumen tubes were inserted under the guidance of a fibre-optic bronchoscope. Optimal depth was defined as the proximal surface of the bronchial cuff positioned just below the carina. RESULTS There was a statistically significant positive correlation between body height and the optimal depth of insertion (r = 0.61, P < 0.0001); however, the correlation coefficient was low. The actual optimal depth of insertion of one patient was even 4.5 cm shorter than that obtained from the equation. CONCLUSION Although there was a statistically significant correlation between body height and the optimal depth of insertion of left sided double lumen tubes in adult patients of short stature (< or = 155 cm), clinical application of the equation is not warranted and these tubes should be inserted under direct vision with a fibre-optic bronchoscope.

Abstract
We managed a patient with a huge ovarian tumor (15 kg). The patient was a 50-year-old woman and could not take the supine position because of the tumor causing respiratory embarrassment. An epidural catheter was inserted 3 cm cephalad via the Th 11-12 interspace in the right lateral position. Three milliliters of 1% mepivacaine was injected epidurally for test dose and produced hypesthesia of Th 9-12 five min after the injection. Additional 3 ml of 1% mepivacaine was injected epidurally, which widened the hypesthesia to Th 5-L 2. Intra-arterial pressure was monitored continuously. Under epidural anesthesia without sedation, 11,000 ml of fluid was suctioned slowly from the cyst in 20 min, during which time remarkable hemodynamic derangement did not occur. The patient was turned into the supine position and the trachea was intubated. Laparotomy was performed under general anesthesia. During the surgery, respiratory and hemodynamic conditions were stable. On the following day, chest radiography demonstrated an abnormal shadow in the lower lobe of the right lung. It disappeared the next day without any treatment. Anesthetic management of patients with huge abdominal tumor is also discussed.

Abstract
BACKGROUND AND OBJECTIVES Local anesthetics in blood absorbed from the epidural space attenuate bronchial hyperreactivity to chemical stimuli. However, it is not documented whether local anesthetics at clinically relevant concentrations improve active wheezing in patients with bronchial asthma. CASE REPORT We managed a 60-year-old man with bronchial asthma and active wheezing under continuous epidural anesthesia using plain lidocaine. The wheezing gradually diminished 20 minutes after the epidural injection of 13 mL 2% lidocaine and completely disappeared over 155 minutes during continuous epidural injection of 2% lidocaine (6 mL/h). The plasma concentrations of lidocaine in arterial blood during the epidural anesthesia ranged from 2.5 to 3.9 microg/mL. Wheezing reappeared 55 minutes after termination of the continuous epidural injection of lidocaine. The plasma concentration of lidocaine at this time was 1.9 microg/mL. CONCLUSIONS At clinically relevant concentrations, lidocaine in the blood absorbed from the epidural space may improve bronchospasm in patients with bronchial asthma.

Abstract
Familial amyloid polyneuropathy (FAP) type I is a rare disease characterized by sensorimotor polyneuropathy, and autonomic nervous system and cardiac conduction system dysfunction. Severe bradyarrhythmia and hypotension may occur during anaesthesia and surgery in patients with the FAP type I. Only one report has been published of a patient with FAP type I who was managed with epidural anaesthesia. The present authors report a 38-year-old Japanese man with a permanent pacemaker because of advanced FAP type I who underwent rotation flap of the gluteus maximus muscle to cover a trophic ulcer in the sacral region under lumbar epidural anaesthesia. Ten millilitres of adrenaline (1:200,000) was injected around the ulcer prior to surgical manipulation. Neither bradycardia nor hypotension developed during the procedures. The haemodynamic changes under lumbar epidural anaesthesia in FAP type I are discussed.

Abstract
An 8-year-old asthmatic child on theophylline was anesthetized with enflurane in nitrous oxide and oxygen. He developed a generalized muscle rigidity after intravenous succinylcholine. Although the maximum rectal temperature was 37.9 degrees C, a marked elevation in muscle-derived enzymes and myoglobinuria were observed. The relations among theophylline which is a derivative of xanthines, inhalation anesthetics, and myoglobinuria are discussed.

Abstract
We describe a patient in whom possible coronary artery spasm occurred during the infusion of trimetaphan. A 55-year-old man with a meningioma was scheduled for surgical excision of the tumour. He denied any previous history of chest pain. Anaesthesia was maintained with nitrous oxide (67%) in oxygen. The blood pressure before commencement of the surgery was 114/70 mmHg, and the pulse rate was 60 beats min-1. The blood pressure rose to 152/94 mmHg (the pulse rate to 62 beats min-1) during incision of the scalp, and intravenous infusion of trimetaphan was initiated. The blood pressure gradually decreased to 113/58 mmHg (the pulse rate 64 beats min-1) 10 min after start of this infusion, and premature ventricular contractions were evident on the electrocardiogram. Trimetaphan was withheld, and lignocaine was given intravenously. The premature ventricular contractions disappeared but ST segments were elevated. Glyceryl trinitrate was then infused intravenously. The ST segments remained elevated for 5 min, were depressed for 2 min and finally became isoelectric. There were no wide swings in blood pressure or pulse rate during the event. Post-operative laboratory examination revealed no evidence of myocardial infarction. Recovery of the patient was uneventful.

Abstract
A rare case of yolk sac tumor in the cerebellar vermis is reported. A 2-year-old boy developed headaches, vomiting, and an unsteady gait. Later a tumor was demonstrated in the medial part of the cerebellum by gadolinium-enhanced magnetic resonance imaging (MRI). The tumor was totally removed, and the surgery was followed by chemotherapy. Soon after surgery the elevated alphafetoprotein (AFP) levels in the serum and cerebrospinal fluid were observed to decrease to normal levels. Three months later enhanced MRI showed a lesion in the vermis without any elevation of AFP, and the lesion turned out to be a granuloma. Six months after the second surgery a tumor recurred that could not be totally removed. Cranial radiotherapy was given together with chemotherapy, which resulted in a decrease of AFP to the normal range. The patient is doing well without any elevation in AFP at 1 year 6 months after onset. Related problems in the diagnosis and treatment of yolk sac tumors are discussed.

Abstract
Histological studies using three lectins, lens culinaris agglutinin, soybean agglutinin, and Ulex europaeus agglutinin-I, were carried out in a case of coexistent lichen sclerosus et atrophicus and morphea, five cases of morphea, and two cases of lichen sclerosus et atrophicus. The lectin staining patterns of the formaldehyde-fixed epidermis of patients with morphea were not different from those of normal epidermis, but epidermis of patients with lichen sclerosus et atrophicus showed different staining patterns. Lens culinaris agglutinin stained the basal and the spinous layers of the normal epidermis and that of patients with morphea but stained only the basal cells of the epidermis from patients with lichen sclerosus et atrophicus; epidermal Ulex europaeus agglutinin binding was observed only in the cases of lichen sclerosus et atrophicus. Moreover, in the patient with coexistent diseases, the morphea lesion showed the staining profiles of morphea and the lichen sclerosus et atrophicus lesion showed the staining patterns of lichen sclerosus et atrophicus, respectively.

Abstract
The "afterdrop" in body temperature (TEMP) following adequate rewarming from hypothermic cardiopulmonary bypass (CPB) is frequently observed. This temperature drop sometimes accompanied by shivering results in increased myocardial oxygen demand. We investigated the relations between the afterdrop and use of vasodilators after CPB. For vasodilator therapy, PGE1 at the rate of 0.025-0.088 microgram.kg-1.min-1 (Prostaglandin Low Doses, PLD; n = 8), 0.107-0.136 microgram.kg-1.min-1 (Prostaglandin High Doses, PHD; n = 7), or phentolamine at 4.1-5.9 micrograms.kg-1.min-1 (PHENT; n = 8) were intravenously infused in 23 adult patients after CPB. During three hour period after CPB, esophageal, rectal, and forehead TEMP are lower in PHENT than in PGE1 groups. There were significant differences between PHD and PHENT group. Finger tip TEMP was lower in PGE1 groups than in PHENT group. There were significant differences between PHD and PHENT group. There were no differences in systemic arterial pressure, cardiac index (CI) and systemic vascular resistance (SVR) at any point between PHD and PHENT groups. It is concluded that PHENT increases the peripheral skin blood flow and TEMP but decreases the visceral TEMP possibly due to vasodilatation of the skin vessels, while PGE1 decreases skin blood flow and TEMP but increases the visceral TEMP, although SVR clearly decreases at the same rate in the two groups.

Abstract
Vasodilators expedite the rewarming process and facilitate weaning from cardiopulmonary bypass (CPB). We continuously infused prostaglandin E1 (PG-E1) at 0.02-0.05 microgram.kg-1.min-1 (n = 11) or phentolamine (PHENT) at 5-10 micrograms.kg-1.min-1 (n = 13) during rewarming from mild hypothermic CPB. Rectal temperature was 33.3 +/- 1.7 degrees C in PG-E1 group vs. 31.3 +/- 1.3 degrees C in PHENT group at 30 minutes, and 34.0 +/- 1.2 degrees C vs. 32.7 +/- 1.1 degrees C at 40 minutes from the start of rewarming. There were significant differences (P less than 0.01 at 30 min, P less than 0.05 at 40 min) in rectal temperature between the two groups. There were no differences in perfusion index of CPB, arterial perfusion temperature, mean arterial pressure, systemic vascular resistance as well as esophageal, forehead or palm skin temperatures at any point between the two groups. The required time for weaning from CPB was significantly shorter in PG-E1 than in PHENT group (P less than 0.01, 36 +/- 8 min vs. 46 +/- 11 min). Our results also strongly suggest that PG-E1 preferentially improves splanchnic blood flow.

Abstract
The relationship between skin color, delayed erythema, and delayed tanning (DT) elicited by a single exposure of UVB was investigated. Both constitutive and facultative pigmentation were determined by skin reflectance using a melanometer. Skin reflectance using visible light was well correlated to the minimal immediate pigment darkening dose elicited by UVA irradiation, which may relate to epidermal melanin content, a determinant of skin color. Minimal erythemal dose (MED) was well correlated to skin color, but there was less correlation between minimal melanogenic dose and skin color or the MED, since melanogenesis is controlled by genetic factors. DT also correlated to the dose of UVB in terms of MED. A coefficient of the regression line of DT may suggest the tanning capacity of skin. The possibility of detecting mild photosensitivity in individuals from a regression line of the MED on skin color is suggested.
