A survey of the biting midges of the Genus Culicoides was conducted by a joint effort of numerous U.S. and Korean personnel throughout South Korea for seven years from 1965 through 1973 (except 1968, 1971) using New Jersey light traps set up at fifty-nine (59) different locations, to find out the seasonal succession and geographical distribution of the said insects both on an individual species basis and as a whole, and to evaluate the medical significance and epidemiology of these insects. This provides some of the basic knowledge needed for prevention of filarial and virus transmission of diseases owing to these insects. As a result the following results were obtained: Sixteen (16) species hitherto unrecorded were added to the fauna of biting midges known from South Korea. Together with the already recorded fourteen (14) species, this makes the total number of species of these insects in South Korea thirty (30).Through the monthly tabulation of the collected specimens it was possible to find out the general seasonal succession of these insects as well as their sex ratio. Based on the data obtained the geographical distributions of the biting midges of the Genus Culicoides so far recorded in Korea were classified into the following four (4) types: The species which are very widely spread throughout south Korea. The species which are spread in central South Korea and supposed to occur in North Korea. The species which were collected from coastal areas and southern island. The species which were collected from Cheju-do.

We report a case of adult granulosa cell tumor arising in the scrotal tunics. The patient was a 34-year-old man who presented with right scrotal swelling, first noticed four months previously. Under the initial clinical impression of epididymo-orchitis, antibiotic treatment was instituted but there was no response. The paratesticular nodules revealed by ultrasound and magnetic resonance imaging mimicked intratesticular lesion, and radical orchiectomy was performed. Although several cases of adult testicular granulosa cell tumor, have been reported, the occurrence of this entity in the paratesticular area has not, as far as we are aware, been previously described.

Rumex japonicus Houttuyn are ubiquitous plants, which are found in marshes or in wet areas. The root of Rumex japonicus Houttuyn has been used for the treatment of skin diseases including fungal infections of the skin since older times in Japan and China. This study was undertaken to investigate the antifungal activity of the alcoholbenzene extract of Rumex japonicus Houttuyn in vitro. During this experiment the extracts of Rumex japonicus Houttuyn were diluted seriaIly in the Sabouraud's dextrose agar and fungal mats or fungal suspensions of isolated strains of dermatophytes were inoculated into each medium containing different concentrations of test materials. Then their growth was observed for 2 weeks or 10 days at room temperature. (countinued...)

Mach bands, a visual phenomenon resulting from lateral inhibitory impulsess in the retina, are recognized aslucent or dense lines at the borders of different radiographic densities. A number of clinical situations have been described in which Mach bands may cause difficulty in radiographic diagnosis. Photodensitometric measurement of the film can differentiate the true change in film density from the Mach band which is an optical illusion. Authors present several examples of photodensitometric tracings of Mach bands, with the brief review of themechanism of their production.

There have been increasing interests of diabetes in the realm of plastic surgery due to problems like foot ulcer as a complication, delayed wound healing or higher failure rates of flap surgery. Main pathology in diabetes is microvascular compromise as well as metabolic derangements. The disturbance in microvascular circulation results in ischemic environments in the body and acts as a main factor that determines the limit of reconstructive or aesthetic plastic surgery. A useful method to overcome such problems is the use of hyperbaric oxygen therapy, which is known to be effective in the treatment of ischemic skin ulcer or osteoradionecrosis. However, there have been few studies on the survival of diabetic random skin flap or the effects of hyperbaric oxygenation directed to increase survival of such flap. In our study, we supposed that the survival of diabetic random skin flap was diminished owing to compromised microvascular pathology and blood rheology, and metabolic derangements, so we hypothesized that hyperbaric oxygen therapy has both reversible and irreversible effects on the survival of ischemic random skin flap in Streptozotocin-induced diabetic rats. Increase of local transcutaneous oxygen concentration, O2 affinity in blood and dysmorphogenesis of red blood cells are reversible and relatively short-term effects and promotion of neoangiogenesis is irreversible or long-term effects. We intended to confirm that hyperbaric rats and to compare the effects between preoperative and postoperative hyperbaric oxygenation on the survival of such flap. And we expect the additional effects of hyperbaric oxygenation on metabolism in diabetic rat, such as lowering the blood glucose level and solving the arrested weight gain. We divided Streptozotocin-induced diabetic rats into three groups: the first was non-treatment diabetic group, the second was preoperative hyperbaric oxygen treated diabetic group(100% O2, 2 atm, 90min, 15sessions, twice a day), and the third was postoperative hyperbaric oxygen treated group(100% O2, 2atm, 90min, 15sessions, twice a day). After elevation of random skin flap on dorsum of diabetic rats, we evaluated the extent of flap survival by measuring the necrotic areas at 3rd, 7th, 10th, and 13th postoperative days. At that time, we intended to evaluate both effects on flap survival by preoperative and postoperative hyperbaric oxygen therapy. As a result, flap survival of non-treated diabetic group was 41% at 13th postoperative days. In diabetic groups with preoperative and postoperative hyperbaric oxygen therapy, flap survival were increased to 64.6% and 62.4% respectively. Diabetic groups with hyperbaric oxygen therapy have a tendency of meaningful decrement in blood glucose level. However, there were no meaningful differences between preoperative and postoperative hyperbaric oxygen therapy. Hyperbaric oxygen therapy has no effective correlations with body weight changes. We conclude that hyperbaric oxygen therapy has some useful effects on the survival of diabetic random skin flap.

Breast cancer is the most common malignancy of women in industrialized countries and the third in Korean women. There have been a lot of studies on biologic behaviors as well as on the prognostic factors of the breast cancer. In this study, the expression of hormone receptors (estrogen receptor ; ER, progesterone receptor ; PR, and androgen receptor ; AR), bcl-2 and Rb proteins were immunostained on 60 infiltrating ductal carcinomas of the breast. The results were evaluated in relation with the age, histologic grade, tumor size, and status of lymph node metastasis. The expression of ER and PR had a significant inverse correlation with the histologic grade (p<0.001). The expression of AR was significantly correlated with the expression of ER (p=0.039) and PR (p=0.009), but not with other factors such as age, histologic grade, tumor size, and status of lymph node metastasis. There was no relationship between bcl-2 protein expresssion and other prognostic factors, except with the expression of ER. Rb protein expression had a significant positive relationship with PR (p=0.05) and the degree of positivity was correlated with histologic grade (p=0.002). In conclusion, this result suggests that expression of AR is well correlated with ER and PR. bcl-2 has no prognostic value. The significance of Rb protein expression remained to be studied.
