  • Herpes zoster (HZ) is the secondary manifestation of an earlier infection with the varicella-zoster virus in one or more dermatomes. As reactivation of the virus is linked to an age-related diminished virus-specific and cell-mediated immunity, HZ develops mainly in elderly people. Acute zoster is painful, but does not incur lasting morbidity. Reactivation of the varicella-zoster virus in the trigeminal nerve (Herpes zoster) occur with severe pain and rash in the oro-facial region. The acute pain decreases as the rash begins to heal. Postherpetic neuralgia(PHN), the most frequent complication of herpes zoster, is usually defined as pain in the involved dermatome that is still present 3 month after rash onset. The clinical characteristics of PHN are, eposodic stabbing pain, burning pain and allodynia, with hypoesthesia and/or dysesthesia. $Neurometer^{(R)}$(neuroselective sensory nerve conduction threshold: sNCT, Automated current perception threshold: CPT, neurotron incorporated. Baltimore, Maryland. 21209 U.S.A.) is convenient, rapid and noninvasive, and allows objective assessment of sensory disturbance. This case is about the postherptic neuralgia patient assessed with $Neurometer^{(R)}$. From this case, we reviewed the pathophysiology and the treatment of PHN and recommend the assessment of pain intensity with $Neurometer^{(R)}$ as quantitative and objective method.

  • To estimate the spawning period the annual change of gonadosomatic index (GSI) were examined from January 2000 to December 2001. Fecundity, spawning frequency and egg diameter were measured by ocular observation. Germ cell differentiation during gametogenesis, the reproductive cycle and the first sexual maturity of greenling Hexagrammos otakii were observed under light microscopy from January to December, 2000. GSI began to increase in August and reached the maximum in November when ovary was getting mature. The reproductive cycle of H. otakii can be divided into five successive stages in females: early growing stage (July), late growing stage (July to August), mature stage (September to October), ripe and spent stage (September to December), and recovery and resting stage (December to June). Males showed four successive stages : growing (June to August), mature (August to October), ripe and spent (September to December), and recovery and resting stage (December to May). According to the frequency distributions of egg diameter in spawning season, H. otakii could be one of polycyclic species spawning 2 times or more during one spawning season. Number of total eggs and mature eggs in the absolute fecundity were related to the standard length and body weight, respectively. Number of total eggs and mature eggs in relative fecundity were also proportional to the standard length, but rather these numbers decreased with body weight. Percentages of first sexual maturity of females and males in greenling were over 50% from 19.1 to 21.1cm in length, and 100% for fish over 25.1cm in length. Therefore, both sexes are ready to reproduce after one year old.

  • Small cell lung cancer is characterized by an aggressive clinical course and a high tendency for early dissemination in spite of a good chemotherapy response. Topotecan is a topoisomerase I inhibitor, and it is used as second-line treatment for small cell lung cancer. The reported dose-limiting adverse reactions to topotecan are mainly hematologic. Yet pulmonary toxicity associated with topotecan is known to be rare. We report here on a case that showed the development of acute respiratory distress syndrome during the 3rd cycle of topotecan chemotherapy in a patient with small cell lung cancer. He developed dyspnea and respiratory failure, and the chest CT scan revealed diffuse ground-glass opacity that was probably due to chemotherapy-related pulmonary toxicity. He finally died of acute respiratory distress syndrome.

  • $\beta$-Sitosterol is the major phytosterol in higher plants, including fruits and vegetables. The molecule has been shown to have the potential for prevention and therapy for human cancer. We investigated the effects of $\beta$-sitosterol on the cell proliferation of HCT116 human colon cancer cells in order to understand its anti-proliferative mechanism. $\beta$-Sitosterol treatment resulted in the inhibition of cell proliferation in a concentration-dependent manner. The anti-proliferative effect of HCT116 cells by $\beta$-sitosterol was associated with formation of apoptotic bodies and degradation of $\beta$-catenin protein. In addition, $\beta$-sitosterol-treatment induced a marked accumulation of tumor suppressor p53 and a concomitant induction of cyclin-dependent kinase (Cdk) inhibitor p21 without alteration in the levels of cyclins and Cdks. Taken together, these findings provide important new insights into the possible molecular mechanisms of the anti-cancer activity of $\beta$-sitosterol.

  • To clarify the annual reproductive cycle of the Korean perch, Coreoperca herzi, the seasonal changes in gonadosomatic index (GSI), hepatosomatic index (HSI), histological aspects of gonad and liver, and plasma levels of sex steroid hormones were investigated from June 1994 to April 1996. The annual variations of GSI and HSI were positively related to the plasma levels of sex steroid hormones. Estradiol-$17{\beta}$ (E2) and testosterone levels were raised during the April to May. Based on the related results, annual reproductive cycle of the fish could be divided into five successive stages; 1) Growing stage (from February to March: GSI was increased rapidly and oocytes with yolk vesicle was increased. Nucleus migrates toward the animal pole. Spermatids were activated from the epithelial tissue of lobuli). 2) Maturation and spawning stage (from April to June: Oocytes were accumulated yolk globules. Active spermatogenesis was observed). 3) Degeneration or stagnation phase (from July to August). 4) Recovery phase (from September to November) and 5) resting phase (from December to January). The main spawning period was in May.

  • The ovary of the spotted flounder Verasper variegatus is a conical bag in shape and is bilateral structure develops lengthily from the posterior of the abdomen to the end of the anal fin. The testis also is bilateral in structure, usually located in small size in the abdomen. In females, the gonadosomatic index (GSI) showed very low from March to July, and then began to increase from August, thereafter reached the maximum in January through out the year. In males, the GSI reached the maximum (1.7) in January through out the year, as seen in females. Compared with the male GSI in other fishes, the maximum GSI of this species were very lower than those of other fishes. According to the distributions of egg diameter in the spawning season, it is assumed that the spotted flounder spawn four times or more in the spawning season. The total length of female and male reached 50% first sexual maturity were 42.0~44.0 and 28.0~30.0cm, respectively and total length of female and male reached 100% maturity were 44.0 and 32.0cm, respectively. The reproductive cycle could be classified into four successive developmental stages: growing stage (August~October), mature stage (November~December), ripe and spent stage (December~February), degenerative and resting stage (March~July).

  • Vaginal cytology with behavioral observation was performed in 34 estrous cycles in 16 Miniature Schnauzer dogs to evaluate the its usefulness. The mean duration of proestrus and estrus in Miniature Schnauzer based on behavioral observation and vaginal cytology was $7.58{\pm}1.50$ (Mean ${\pm}$S.D., range: $5{\sim}10$) and $8.46{\pm}2.82\;(6{\sim}17)$ days for proestrus, and $6.97{\pm}1.66\;(4{\sim}10)$ and $10.29{\pm}2.61\;(6{\sim}19)$ days for estrus, respectively. The duration of each phase of the estrous cycle was not significantly different based on between behavioral observation and vaginal cytology. The gestational length from the first day of male acceptance was $66.55{\pm}2.91\;(64{\sim}76)$ days, $57.70{\pm}1.92\;(54{\sim}62)$ days from the first male refusal, and $56.90{\pm}1.62\;(54{\sim}60)$ days from the onset of cytologic diestrus, respectively. Vaginal cytology during the estrous cycle were significantly characteristic of large intermediate cells in proestrus, anuclear cells in estrus, small intermediate cells in diestrus, and parabasal cells and small intermediate cells in anestrus (p<0.001), respectively. Cornification index (CI) by vaginal cytology was higher in proestrus ($69.90{\pm}1.44%$) and estrus ($91.35{\pm}1.09%$), then it was decreased in diestrus ($13.53{\pm}1.28%$) and anestrus ($1.16{\pm}1.26%$).

  • The aim of this study was to estimate of ovulation time and parturition day at the same time as breeding in small dog by vaginal cytology and to confirm the accuracy by comparing the expected parturition day and the real one. Characteristic features of vaginal cytology during the estrous cycle were the high proportion of large intermediate cell, superficial cell, anuclear cell and erythrocyte in proestrus, superficial cell and anuclear cell in estrus, parabasal cell, small intermediate cell, large intermediate cell and leukocyte in diestrus, parabasal cell and small intermediate in anestrus, respectively. When day 0 was the parturition day, the period of pregnancy is 67.45(64~75) days when the cornification index (CI) is over 90%. Also, on the basis of ovulation day, 63.65(59~66) days was confirmed, and 57.0(52~60) days was confirmed based on the first day of diestrus. There are the gap of 4 days between the day being over 90% in CI and ovulation day. On the basis of this, when expecting parturition day based on the day being over 90% in CI by vaginal cytology, 18.1% was produced in the same of the expected parturition day and the real one, 30.3% and 33.3% were produced in the gap of one day and two days, respectively so, the accuracy within two days was 81.7%. In addition, based on the first day of diestrus, it also was identified to 81.7% as the difference between the expected parturition day and the real one within 2 days. It demonstrated there are any difference between any expected parturition day by vaginal cytology. Thus on the basis of the day of being over 90% CI, it is fully thought to using clinically due to the possibility of prediction the parturition day at the same time as the determination of the proper time of the optimal mating time.

  • Bronchiectasis is defined as an abnormal, irreversible dilatation of the bronchi, which may result from a number of possible causes, and the recognition of these causes may lead to a specific management strategy. Immunodeficiency is known as one of the conditions associated with bronchiectasis. X-linked agammaglobulinemia is a rare inheritable immunodeficiency disorder, caused by a differentiation block, leading almost to the complete absence of B lymphocytes and plasma cells. The affected protein is a cytoplasmic protein tyrosine kinase, Bruton's tyrosine kinase. The early detection and treatment with immunoglobulin replacement are most important for the management of recurrent infections and for reducing severe complications. We report a 20-year-old male patient, with X-linked agammaglobulinemia associated with bilateral bronchiectasis, carrying a missense mutation(R520P) in the BTK gene.

  • Purpose: We evaluated the results of surgical treatment for metastatic pathologic or impending pathologic fractures. Materials and Methods: From January 2004 to December 2007, 18 patients 19 cases were included. Male were 6 and female were 12. The mean age was 65.1. Mean follow up period was 15.2 months. Pathologic fractures were 14 and impending pathologic fractures were 5. MSTS score, periodic radiologic follow up and postoperative complications were evaluated. Results: The primary malignancies were 6 cases of multiple myeloma, 4 cases of renal cell carcinoma, 2 cases of cholangiocarcinoma, 2 cases of colon cancer, 2 cases of breast cancer and 2 cases of leiomyosarcoma. Metastatic lesions were 10 cases of femur, 4 cases of clavicle, 2 cases of humerus, 2 cases of tibia and 1 case of radius. Surgical options were curettage, cementation, internal fixation and arthroplasty. Mean MSTS score was 15.9. Postoperative complications were 1 case of infection, 1 case of local recurrence and 1 case of implant loosening. Ten patients were alive with disease, 8 patients died of disease. Conclusion: Surgical treatment of metastatic skeletal lesions allowed early ambulation and improving dexterity. It improved pain and emotional acceptance. Surgery is necessary for improving qualities of remaining lives.
