  • Pathological and bacteriological studies were made of a total of 111 udders from slaughtered Korean native cows originating from various locations in Chonnam province. Incidence of supernumerary teats was 8.1%. Gross lesions were found in 21.4% of mucous membranes of total teat cisterns; these lesions comprised epithelial hyperplasia (12.6%), congestion (4.1%), slight fibrosis (3.8%) and severe fibrosis with congestion (0.9%). Gross lesions in the glandular tissues were found in 35.1% of cows; these lesions comprised slight fibrosis (27.9%), moderate fibrosis (6.3%) and severe fibrosis with pus (0.9%). Mastitis was found only in one cow. One hundred and twenty-five strains of microorganisms were isolated from mammary gland fragments of the cows. Pathogens most commonly isolated were Staphylococcus spp.; most of them were minor mammary pathogens. Major mammary pathogens were Streptococcus spp. (9.6%) and E. coli (2.4%). Most of the isolates were susceptible to many of 13 antimicrobial agents used, but Streptococcus spp. and Gram-negative rods showed resistance to 7 and 8 agents, respectively. 97.5% of the isolates showed susceptibility to amoxicillin, but only 55.8% to erythromycin.

  • Human papillomaviruses (HPVs) are small, non-enveloped, double-stranded DNA viruses that infect epithelial tissues. Specific genotypes of human papillomavirus are the single most common etiological agents of cervical intraepithelial lesions and cervical cancer. Cervical cancer usually arises at squamous metaplastic epithelium of transformation zone (TZ) of the cervix featuring infection with one or more oncogenic or high-risk HPV (HR-HPV) types. A hospital-based study in a rural set up was carried out to understand the association of HR-HPV with squamous intraepithelial lesions (SILs) and cervical cancer. In the present study, HR-HPV was detected in 65.7% of low-grade squamous intraepithelial lesions (LSILs), 84.6% of high-grade squamous intraepithelial lesions (HSILs) and 94% of cervical cancer as compared to 10.7% of controls. The association of HPV infection with SIL and cervical cancer was analyzed with Chi square test (p<0.001). The significant association found confirmed that detection of HR-HPV is a suitable candidate for early identification of cervical precancerous lesions and in the prevention of cervical cancer in India.

  • Human papillomaviruses (HPVs) remain a serious world health problem due to their association with cervical and head and neck cancers. While over 100 HPV types have been identified, only a few subtypes are associated with malignancies. HPV 16 and 18 are the most prevalent oncogenic types in head and neck cancers. Although it has been proven that some subsets of benign and malignant head and neck lesions are associated with HPV, the general population have very little awareness and knowledge of their association with HPV. Therefore, the purpose of this study was to determine the knowledge of HPV and its links with head and neck benign and malignant lesions in a group of Pakistani dental patients who attended the Dental Department of the Sandeman provincial hospital in Quetta, Pakistan. One hundred and ninety-two patients were recruited and requested to answer a questionnaire. It was revealed that there was a low level of knowledge about HPV and its association with head and neck benign and malignant lesions among the participants. This result suggested that more education regarding the relationship of HPV in inducing head and neck benign and malignant lesions is required in this group of patients.

  • In order to evaluate the prevention effect of Sunkiwhajung-tang (SWT) which has been used as a traditional prescription for the treatment of digestive disease in Korea on the gastric ulcer induced by indomethacin in rats, the changes of number and size of ulcerative lesions, parietal, chief, Grimelius and Serotonin-positive cells in the peri-ulcerative tissues were detected with histological examinations of ulcerative and peri-ulcerative lesions after oral injections of SWT extracts (125, 250 and 500 mg/kg, respectively). SWT prevented to a great extent the expected indomethacin-induced elevation in hemorrhagic ulcerative lesions, the number and size of ulcerative lesions, and the number of parietal cell, chief cell, Grimelius-positive cells and Serotonin-positive cells in the peri-ulcerative lesions in a dose dependent manner. These results provide a story evidence that SWT produced an protective effect on gastric ulcer induced by indomethacin. Determination of the specific mechanisms involved in the protective effect of SWT on the gastric ulcer will require additional study.

  • Background: Vstibular evoked myogenic potentials(VEMP) have been known to be useful documenting abnormality in patients with various vestibular disorders and brainstem lesions but the studies of VEMP in patients with hemispheric lesions are rare. Methods: We recorded VEMP in 21 consecutive patients with acute ischemic stroke in the supratentorial lesions without evidence of brainstem or vestibular end organ lesions. All patients underwent magnetic resonance imaging and the main outcome measures of VEMP were recorded in all subjects. We interpreted each parameters of VEMP using our normal laboratory data. Results: VEMP abnormalities(prolonged latency or asymmetry of amplitude) were found in 57%(12/21) of acute infarction patients with supratentorial lesions. Bilateral VEMP abnormalities were found in six patients and unilateral abnormalities were found in another six patients with ipsilateral abnormalities in the three and controlateral abnormalities in the three patients. Conclusions: VEMP abnormalities were found in supratentorial stroke patients in our studies and this findings suggest supranuclear control may affect the generation of VEMP potentials.

  • To determine the usefulness on fine needle aspiration cytology(FNAC) of bone lesions and the complementary role of FNAC and percutaneous needle biopsy, 75 cases of FNAC taken from bone lesions were analyzed. Correlations with histopathology were possible in 47 cases, including 14 cases of simultaneous core biopsy and 33 cases of subsequent open biopsy due to inadequate aspirates. Among 75 cases, 4 cases were benign tumors and tumor-like lesion, 11 cases were malignant primary bone tumors, 17 cases were metastatic tumors, and 43 cases were nonneoplastic bone lesions. The aspirates were adequate in 35 cases(46.7%), in all of which the discrimination between benignancy and malignancy was possible. The main reason for Inadequate aspirates was due to hypocellularity. In the cases of aspiration and core biopsy simultaneously done, the diagnostic accuracy of aspiration, core biopsy, and both were 57%(8/14), 78.6%(11/14), and 92.9%(13/14), respectively. We conclude that a final diagnosis based on cytology is possible with the adequate aspirates and the clinical and radiological findings. Also we confirm the complementary role between FNAC and core biopsy in bone lesions.

  • The author observed and compared the radiographic features of 49 cases of the fibrous dysplasia and 14 cases of the ossifying fibroma in the osteoblastic or mature stage radiologically and histopathologically. The obtained results were as follows: 1. Fibrous dysplasia occurred most frequently in the 2nd decade, but ossifying fibroma in the 3rd and 4th decades, and both lesions occurred with slight predilection in females. 2. In most cases, chief complaints were painless facial swelling. And 61.1% of fibrous dysplasia occurred in the maxilla, 92.9% of ossifying fibroma in the mandible, and most of these lesions occurred in the premolar-molar region. 3. In the mandibular lesions, ossifying fibroma was shown more oval and round shape. but fibrous dysplasia was shown fusiform shape. 4. Fibrous dysplasia was shown homogeneously distributed. complete radiopaque shadow at 63%, and ossifying fibroma was shown concentric. mixed appearance of radiolucent and radiopaque shadow at 92.9%. 5. Fibrous dysplasia was entirely shown poorly outlined and blended to normal surrounding bone, but ossifying fibroma was shown well-defined border. 6. Cortical thinning and expansion were observed in these lesions. but degree of cortical expansion was more severe in ossifying fibroma than fibrous dysplasia. 7. Loss of lamina dura. tooth displacement. and displacement of mandibular canal were observed in both lesions. but root resorption was observed in ossifying fibroma only.

  • Thirty-four consecutive cases of thyroglossal duct lesions in children were reviewed at the Department of Surgery, Chonbuk National University Hospital. Twenty patients were males, and the most prevalent age of discovering was 2 to 4 years (52.9%). Resection was performed within 2 years after discovering the lesions in 19 cases, but was delayed untill 4 to 10 years in 6 cases. Cystic lesions (85.3%) were 5.8 times more common than fistulas. A midline upper neck mass was found in every cystic cases, and a draining sinus at hyoid region was noticed in fistula patients. The location of the lesion was on the hyoid bone in 34 cases, at the midline in 31 cases, slightly to the left in 2 cases, and slightly to the right in 1. Two cases were misdiagnosed as lymphadenopathy, and a single case of ectopic thyroid gland was misinterpreted as a thyroglossal duct cyst. Modified Sistrunk operation was performed in twenty-three cases(67.6%), Sistrunk operation in 9(26.5%), and cyst excision in 2(5.9%). Postoperative complications occurred in 4 cases(11.8%); 2 wound infections and 2 recurrences. One of recurrences was a fistula treated by modified Sistrunk operation, and the other was a cyst treated by cyst excision.

  • Various mucosal lesions are originated in oral cavity and trauma is most common cause of these lesions. Definitive treatment of these lesions is stop of traumatic events and removal. There are two representative removal methods in medical fields; conventional mess or LASER. Compare to conventional mess technique, LASER has several advantages such as bleeding control, pain reduction. Of the various LASER systems, $CO_2$ LASER is regarded as best choice for general practitioners due to its convenience, universal use and high cost/benefit effects. In these article, we report the treatment cases of mucocele, fibroma, and leukoplakias using $CO_2$ LASER. Eventhough there are malignancy potential of oral mucosal lesion especially leukoplakias, careful history taking, clinical examination, and regular check-up will help the general practitioners to manage these lesions. Simple and relatively safe oral mucosal lesions have to be treated more in general dental practitioners.

  • Ultrasound sonography(US) is used to evaluate various diseases of maxillofacial region including salivary glands, soft tissue and jaw lesions because of easy accessibility and no hazard of ionizing radiation. Also, US can offer dynamic study showing real-time images during diagnostic or surgical procedure. US images provide accurate information about the internal features of lesions on the jaw prior to surgical treatment. Doppler images are used to visualize the vascular distribution of the lesions and to provide additional information to enhance diagnostic value. Nevertheless, the clinical application of US imaging is limited in the dental field. This is due to the lack of knowledge about the US image and the image characteristics of the anatomical structures. It is necessary to evaluate the diagnostic value of US and evaluate its usefulness by looking at clinical cases using US images. Therefore, US imaging may be recommended as an assistant image in evaluating jaw lesions. US images provided accurate information about the internal structure of lesions on the jaw prior to surgical treatment, and diagnostic value was enhanced by visualizing the vascular distribution of the lesion using doppler imaging.
