Vaginitis is one of the most common disease in gynecologic field in recent days. About 90% of these patients suffer from the infection of the vagina caused by Gardnerella vaginalis, Candida, or Trichomonas, either alone or in combination. For the effective diagnosis and management, it is essential to get an accurate identification of the causative agent. Applying simple and easy diagnostic methods such as pH of vaginal discharge, amine test and microscopic examination of wet mount preparation of normal saline and 10% KOH to 549 cases of randomly selected patients visiting Out-patient Department of Obstetrics and Gynecology of Yeung-nam University Hospital through May 1st to Sept. 31st, 1987, the following results were obtained. 1. In the Gardnerella vaginitis vaginal pH was more than 5.0 in 81.0% of total cases, positive amine test in 62.8%, decreased lactobacilli in 77.4% & decreased WBC counts in 70.1%, In the Trichomonas vaginitis vaginal pH more than 5.0 was noted in 93.3% of the cases, negative amine test in 90%, decreased lactobacilli in 90% & increased WBC counts in 93.3%, whereas Candida vaginitis and normal groups showed vaginal pH of 3.0~4.0 in 83.2%, negative amine test in 100%, normal distribution of lactobacilli in 89.7%, normal WBC counts in 72.4%. 2. The accuracy rates of physical diagnosis by wet mount preparation of normal saline and 10% KOH revealed 26.3%, 47.5% % 70,0% in Gardnerella vaginitis, Candida vaginitis, and Trichomonas vaginitis, respectively. The vaginal pH and amine test showed 83.2% of accuracy rate in Candida vaginitis group, 60.6% in Gardnerella vaginitis group and 83.3% III Trichomonas vaginitis group. 3. In 23 cases of Gardnerella vaginitis showing vaginal pH of 3.0 or 4.0 and positive amine test, the clue cells were observed in 10% or less in 12 cases, 30% in 5 cases, 50% in 4 cases and 50% or more in 2 cases. In summary vaginal pH and amine test could be useful in screening and differentiating the different types of infectious vaginitis. Furthermore by adding microscopic examination of normal saline and 10% KOH wet mount preparation to them, they not only could obtain higher diagnostic accuracy rate but would be more valuable in selecting the patients requiring cultures to confirm the diagnoses.

Langerhans' cell histiocytosis (LCH), known for histiocytosis X, is a clinicopathologic entity characterized by proliferation of Langerhans' cells (LCs) throughout the body including the reticuloendothelial system, bone, and skin. LCs is currently considered as a distinct type of histlocytic cells, not primarily phagocytic in nature. Recently, we could make the diagnosis on cytologic specimen in a 3 month-old-boy and a 3 year-old-boy. The cases were diagnosed on scraping smear from the skin and fine needle aspiration cytology from the lymph node, respectively. The characteristic cytologic features of Langerhans' cells were noted in the nuclei, namely eccentric, indented, elongated, and grooved nuclei. The cells also had abundant and acidophilic cytoplasm. The cytologic diagnoses were confirmed on the biopsies from the skin and lymph node, respectively.

Endometrial papillary serous carcinoma (EPSC) is a distinct variant of endometrial adenocarcinoma that histologically resembles ovarian serous papillary adenocarcinoma and has an aggressive clinical course. Usually, the tumor is diagnosed at the advanced stage. The tumor has well confused with metastatic ovarian tumor of identical histology. Dignosis of EPSC should be considered when the cervico-vaginal smear reveals nomerous papillary clusters of tumor cells with macronucleoli and psammoma bodies. Recently, we have experienced two cases of EPSC diagnosed on cervico-vaginal smears, which revealed characteristic cytologic features including numerous papillary clusters of tumor cells with macronucleoli. The cytologic diagnoses were confirmed on histologic sections.

자궁경부암은 다른 암과 달리 전암(前癌) 단계가 존재하므로 조기에 발견할 경우 생존율이 높다. 그러나 검체 적정성의 부족과 검체 체취의 오류로 인해 질병이 있음에도 음성으로 나타나는 위음성률이 높다. 따라서 본 논문에서는 세포 도말검사에서 사용되는 자궁 경부진 세포에서 암종 세포를 추출하는 방법을 제안한다. 영상의 배경 그리고 핵과 세포질 영역의 구분이 중요하기 때문에 조기 자궁 경부 세포진 영상에서 핵의 추출은 Lighting Compensation을 적용하여 영상을 보정하고, 명암도 분포가 가장 작은 B 채널과 명암도 분포가 높은 R채널과의 OR 연산을 적용한 후, $3{\times}3$마스크를 이용하여 잡음을 제거한다. 잡음이 제거된 영상을 이진화하고 Grassfire 알고리즘을 이용하여 암종 세포의 후보 객체를 추출한다. 추출된 세포 객체에서 핵의 크기, 핵의 면적과 핵의 외곽의 방향성 정보를 이용하여 백혈구와 잡음으로 구성된 객체를 제거한다. 세포 도말검사 과정에서 겹쳐진 부분은 거리 함수와 명암도를 이용하여 마커를 추출하고 추출된 마커 정보와 워터쉐드 알고리즘을 적용하여 겹쳐진 암종 세포를 분리한다. 자궁경부 편평 세포진 400 배율 영상과 자궁 경부 상피내 종양 400 배율 영상을 대상으로 실험한 결과, 기존의 자궁 경부진 암종 세포 추출 방법보다 효과적으로 암종 세포 영역이 추출되는 것을 확인하였다.

Resistance of Plcsmodium species to antimalarial agents has become increasingly challenging to the management and prevention of malaria. We experienced an imported case of tertian malaria due to Plasmodum viuax relapsed after a seemingly successful treatment with conventional course of hydroxychloroquine and primaquine. A 35-year-old man developed fever three days after return from India and mainland China. After his illness was diagnosed as tertian malaria, he was managed with hydroxy- chloroquine and then primaquine (primaquine base 15 mg/day for 14 days). Thereafter peripheral blood smears showed no malarial parasites, and there was no relapse of symptom until the 55th post-treatment day, however, six months after the above treatment tertian malaria relapsed. He was managed with the same medications again un malaria did not relapse for 10 months.

A 2 years old female beagle dog was examined because of the vaginal discharge and vaginal swelling at 7th day after mating. Abdominal ultrasonography revealed multiple follicular cysts on both ovaries. Also, the ratio of superficial cells was above 90% based on vaginal cytology. She was still in standing heat, with the tail deflected up and flagging when a male sniffed the vulva and attempted to mount. The dog was diagnosed with multiple follicular cysts by vaginal cytology, clinical signs and ultrasonography. The dog was treated with GnRH $50{\mu}g$ injection by intramuscularly. The sizes of the cysts were decreased two weeks after GnRH treatment, and then the dog delivered an offspring at 68th day after last mating. To confirm the stage of estrous cycle, we performed hormone analyses, retrospectively $Estradiol-17{\beta}$ concentration was 78pg/ml at diagnosis. Progesterone concentration was 6.9ng/ml at the last mating, and 66.9ng/ml at diagnosis. Therefore, we confirmed that follicular cysts was observed during diestrous stage in a beagle dog.

Purpose: This study was to examine the differences in health belief variables and HPV (Human Papillomavirus) knowledge in Pap smears according to the stages of change using Trans-theoretical Model (TTM) among married nurses. Methods: The research design was a cross sectional survey. Participants were 387 married nurses working in general hospital located metropolitan city. Measurement variables were perceived threatening, perceived severity, benefits of Pap, HPV knowledge and stages of the change in Pap smear. Results: Classified stages were pre-contemplation 3.9%, contemplation 17.8%, relapsing 29.5%, action 31.0%, and maintenance 17.8%. Accuracy rate of HPV knowledge were low ranging from 15% to 45%. Among the variables, perceived threatening (F=3.56, p=.007), perceived severity (F=9.73, p<.001) and HPV knowledge (F=7.52, p<.001) were significantly different by stages of change. Conclusion: Application of TTM to Pap smears was efficient to know the nurse's level of health behaviors, Health belief variables and HPV knowledge were main factors to identify the stages of change. The continuation of Pap smears and the education in relation to HPV knowledge should be encouraged for married nurses.

Leukemoid reaction has been rarely encountered in dogs. This report describes a case of leukemoid reaction showing extremely elevated leukocyte count. A 10-year-old female Maltese dog was presented with purulent and bloody vaginal discharge. The CBC revealed severe leukemoid reaction ($976\times10^9$ cells/l, reference range 6 to $17\times10^9$ cells/ l) and mild non-regenerative anemia. On the blood smear, elevated leukocytes consist of numerous neutrophils and monocytes only. Radiographic and ultrasonographic examinations revealed generalized enlargement of the uterus, which was filled with a complex fluid. After ovariohysterectomy, Escherichia coli was isolated from the uterine fluid. To author's knowledge, it is the new record of extreme leukemoid reaction caused by local bacterial infection in dogs.

Fine needle aspiration cytologic features of a case of insular carcinoma of the thyroid in a 23-year-old woman who presented a palpable neck mass is described. The aspirate showed cellular smear arranged in trabeculae, solid or loose clusters, and microfillicles in necrotic background. The tumor cells had uniform, small round, hyperchromatic nuclei. The chromatin was finely granular, and nuclear membrane was smooth. Nucleoli were not discernible. Nuclear pleomorphism was minimal. The cytoplasm was usually scanty, pale, poorly outlined, and almostly amphophilic. Sometimes paranuclear cytoplasmic vacuoles were noted. final diagnosis was confirmed by total thyroidectomy as insular carcinoma.
