Hemorrhage*

A 12-year-old castrated Toy Poodle was referred to the Kangwon National University Animal Hospital with an oligotrophic nonunion fracture in the distal 1/3 of the left radius and an intact ulna. After fixation by a locking plate and screws, adipose-derived mesenchymal stem-cell sheets expressing bone morphogenetic protein 7 (BMP-7) were transplanted to the fracture site to enhance the healing activity. The fracture was healed at 9 weeks after surgery. In the present case, the mesenchymal stem-cell sheets expressing BMP-7 promoted bone regeneration and healing in a nonunion fracture.

Forty canine patients with a presumptive diagnosis of the intervertebral disc herniation at the thoracolumbar region were imaged. A neurological examination was performed and all patients were classified under four grades by the examination. The degrees of attenuation of the herniated disc material were measured in Housefield units (HU) in each image. The ratio of the area to herniated disc material and the height to disc material were measured. The clinical grade was correlated with the area ratio of the herniated disc material to the spinal cord, but not correlated with the height ratio of that. In the patients with epidural hemorrhage at surgery, HUs of the herniated disc material was lower than those with no epidural hemorrhage at surgery. Non-contrast computed tomography scans of the spine can be useful in diagnosing acute intervertebral disc disease in chondrodystrophoid breeds, evaluating patient status and identifying concurrent epidural hemorrhage.

This study was performed to investigate histopathologically the effect of amniotic membrane graft (AMG)on haze in deep stromal wound of cornea. The excimer laser phototherapeutic keratectomy (PTK)was used to create the wound model of 150 micrometerdepth, 6.0 mmdiameter area in 72 white rabbitsbilaterally.Each eye was randomized to three groups: control (topical antibiotic alone), contact lens application and AMG. Corneal haze,the number of anterior stromal keratocytes and thickness of the regenerated stroma were evaluated after treatments in corneal wound, and also the morphological changes of anterior stroma connected with corneal haze were analyzed. The score of corneal haze in AMG group was significantly lower than those in the others at postoperative 3 days, 2, 4, 6 and 8 weeks. The anterior stromal keratocytes in AMG group significantly remained more than those in the others at postoperative 3 days. The number of keratocytes and thickness of regenerated stromal tissue in wound area of AMG group were statistically lower as compared with those of the other groups at postoperative 4 weeks. The architecture of stromal lamella was most reg-ular in AMG group. Transmission electron microscopic observation demonstrated that the cells in anterior stroma were the active fibroblastic cells with prominent rough endoplasmic reticulum at postoperative 8 weeks. These findings indicate that corneal haze is closely connected with proliferation of corneal stroma , suggesting that AMG on deep corneal stromal wound reduces corneal haze by preventing proliferation of abnormal collagen and fibroblasts at the anterior stroma of the wound area.

To evaluate the effect of amniotic membrane on corneal wound healing, using the VISX 193-nanometer excimer laser, the wound model of 150 micrometer depth, 6.0 mmdiameter area was created in 30 white rabbits (60 eyes). The treatment of corneal wound was categorized into three groups :topicalantibiotics alone (control), therapeutic contact lens application and amniotic membrane graft. The area of epithelial defect, proliferation of epithelial cells and inflammatory cell infiltration were evaluated during the entire observation period. Epithelial healing rates calculated by radius regression in control, contact lens and amniotic membrane groups were 42.5 micrometer/hr, 33.4 micrometer/hr and 53.4micrometer/hr respectively thus the effect of amniotic membrane was significantly outstanding (P<0.05). The epithelium was healed almost within 72 hours in eyes of amniotic membrane group but significantly delayed in contact lens group. The number of inflammatory cells in stroma were significantly lower in amniotic membrane group than others. The number of PCNA (proliferating cell nuclear antigen) immunoreactive cells has increased in amniotic membrane group than other groups and regionally at basal cell layer of limbus comparing to wound margin at first, third days after treatment. In view of the above findings, amniotic membrane on corneal wound accelerates the process of wound healing, with minimal complications.

Doxorubicin has characteristic chemomyectomy effect of the eyelid without disturbing other eyelid structures, but the major side effect of doxorubicin is the potential for eyelid skin injury as a result of the drug's toxicity in both animal and clinical studies. Verapamil may be used to reduce the dose of doxorubicin and the number of injections that would amplify the toxic effects of doxorubicin. This study was performed to determine whether there is an increase in the toxic effect of the doxorubicin as a result of verapamil pretreatment of the muscle. After 0.5mg, 1.0mg, and 2.0mg doxorubicin was injected in lower eyelids of each group, and equal dose of doxorubicin was injected fo11owing 1.0mg of verapamil injection in lower eyelid of each group, muscle cell loss were measured by light microscopy and side effect was observed. In verapamil and doxorubicin injection group, there was significant differences in the amount of preseptal muscle and even in the pretarsal muscle than the doxorubicin injection group in all doxorubicin doses. Verapamil, injected with a range of doses of doxorubicin, caused suhstantia11y increased muscle loss in the eyelid, compared with injection of doxorubicin alone. Skin ulceration, entropion or ectropion were not visible. Clinically, verapamil cotreatment might be useful to decrease the dose of doxorubicin injected and/or the total number of injections.

BACKGROUND: An increase in ventilation is known to accelerate the rate of the rise of alveolar concentration of inhalation anesthetics and increase the rate of anesthetic induction. However, it is still debatable whether or not a rise of alveolar isoflurane concentrations by increased minute ventilation (MV) actually increases the depth of anesthesia. METHODS: After anesthetic induction by intravenous thiopental and succinylcholine, and after the bispectral index (BIS) had recovered to 75 after intubation, isoflurane anesthesia was begun (inspired concentration:2 vol.%, respiratory rate:12/min, tidal volume: group I; 8 ml/kg, group II; 12 ml/kg). BIS, spectral edge frequency (SEF), blood pressure, pulse rate were recorded 1 minute before induction, and 1, 2, 3, 4, 5, 7 and 10 minutes after isoflurane anesthesia. End-tidal concentrations of isoflurane and CO2 (ET-iso and -CO2) were recorded at 1, 2, 3, 4, 5, 7 and 10 minutes after isoflurane anesthesia. RESULTS: The increase of ET-iso and the decrease of ET-CO2 were significantly fast in group II. There was no difference in BIS and SEF between the two groups. CONCLUSIONS: Increasing MV induced a rapid rise of alveolar isoflurane concentrations, but changes of BIS and SEF were not affected by increased MV.

OBJECTIVES: This study aimed to estimate the completeness of cancer registration with Capture-recapture method. METHODS: The study was conducted in the population based cancer registry of Kwangju, Korea, for which there are three main sources of notification: reports by Korean Central Cancer Registry, reports by pathology data, and the others reports by radiology data, death certificates, etc. The defined cases in three sources were matched by 13 digits Resident Register Number. To derive an estimates, log-linear models were applicated. RESULTS: Overall completeness was estimated to be around 93%. There was some variation with age(consistently high levels below age group 60-74 years, a minimum of 88.6% above 75 years). Among the most common cancer sites, estimates of completeness were highest for thyroid cancer(97.1%), while lower estimates of completeness were derived for stomach cancer(92.3%), liver cancer(92.6%). CONCLUSIONS: Careful application of Capture-recapture method may provide an alternative to traditional approaches for estimating the completeness of cancer registration in Kwangju city.

Jimson weed, also known as Datura stramonium, is a member of the Solanaceae family. Jimson weed was used by American Indians for medicinal and religious purposes. All parts of the Jimson weed plant are poisons, containing the alkaloids atropine, hyoscyamine and scopolamine. So, it is caused by these components to make a anticholinergic toxicity within 6h after ingestion. Initial manifestations include dry mucus membrane, blurred, vision, thirst, difficulty swallowing and speaking, and photophobia, and may be followed by hyperthermia, confusion, agitation, combative behavior, hallucination, urinary retention, seizure and coma. We experienced two patients who developed combative behavior and agitation with pupil dilation caused by Jimson weed. They discharged with improvement after supportive for 2days.

Purpose: This study examined the utility of preliminary magnetic resonance imaging (MRI) measurements in the ultrasound-guided L4 selective nerve root block. Materials and Methods: As a retrospective study, 71 patients, who met the criteria for outpatient visits from March 2016 to December 2017, were included. From March 2016 to February 2017, 31 patients who underwent an L4 nerve root block without MRI were classified as group A, and 40 patients who underwent an L4 nerve root block through MRI measurements from March 2017 to December 2017 were classified as group B. Group A was injected under ultrasound-guidance through the pararadicular approach without a pre-interventional MRI evaluation, and group B was injected under ultrasound-guidance according to the preliminary MRI measurements. The results were assessed using the numeric rating scale scores before, three hours, and two, six, and 12 weeks after the procedure. Results: At three hours after the procedure, the proportion of patients better than good results were 51.6% in group A and 67.5% in group B. At two weeks after the procedure, the proportion of patients with better than good results were 48.4% and 70.0% in groups A and B, respectively; 58.1% and 62.5% of patient of groups A and B, respectively, showed better than good results after six weeks. In 12 weeks after the procedure, the results of group A and B were 67.7% and 62.5%, respectively. At three hours and two weeks after the procedure, group B showed significant symptom improvement than group A (p<0.05). The procedures were repeated 2.8 and 1.7 times in groups A and B, respectively, between two and six weeks for satisfactory pain relief (p<0.05). Conclusion A pre-interventional MRI evaluation might improve pain relief within the initial two weeks after ultrasound-guided L4 selective nerve root block by improving the success rate of the procedure.
