  • A case of metastatic mucoepidermoid carcinoma of the lung, originating from the hard palate, was diagnosed by sputum and bronchial washing cytology. Although the cytologic features of mucoepidermoid carcinoma have been well described, it is easy to confuse mucoepidermoid carcinoma with the more common primary adenocarcinoma or squamous cell carcinoma of the lung. The features distinguishing mucoepidermoid carcinoma from other primary neoplasms include 1) mucus-secreting cells individually and in clusters admixed with other cell components, 2) epidermoid cells identified by the presence of abundant spread-out cytoplasm and an oval dark nucleus and 3) intermediate cells resembling normal ductal epithelial cells with moderate-to-scanty cytoplasm, a central, round vesicular nucleus and a prominent nucleolus. The morphologic features of metastatic mucoepidermoid carcinoma in this case were similar to those of primary salivary mucoepidermoid carcinoma.

  • Immunity is responsible for the defense mechanism of the body but in case of autoimmune diseases, its role gets diverted. Like so many other diseases, asthma is also considered as one of the most common autoimmune diseases to be occurring in community. Asthma is defined as a chronic inflammatory airway disease that is characterized by airway hyper reactivity and mucus hypersecretion that result in intermittent airway obstruction. The incidence of allergic asthma has almost doubled in the past two decades. Although, precise causative mechanism of asthma is unknown, but several mechanisms have been proposed that is immunological, pharmacological and genetic mechanisms, and airway and neurogenic inflammation. The inflammatory process observed in the asthmatic patients is the final result of a complex network of interactions between various immunological cell lineages, its mediators and secreted substances. Thus, among the mechanisms proposed, the immunological one plays a key role. Through this article, we have tried to provide some insight into immunological mechanisms in pathogenesis of asthma.

  • 저자들은 기관지 폐쇄와 기관지성 낭종을 동시에 가지는 매우 귀한 증례를 보고하는 바이다. 형태상 우상엽의 첨구역으로 가는 기관지가 우측 주기관지에서 직접 분지 하였다. 기관지성 낭종은 폐쇄된 구역 기관지와 서로 교통되어 있었으며 모두 점액으로 차 있었다. 이들의 원인은 잘 모르나 태생기 5∼6주 경에 발생하는 단일 인자에 의해서 두가지가 같이 발생하는 것으로 여겨진다.

  • Enteritis occured in a herd of Korean native cattle in Gyeonbug district in February 1977. of 40 cattle ranging in age from 15 to 20 months, 17 had been sick for the past six days with main clinical findings of feces containing mucus and blood. Among affected cattle, feces of 8 cattle were examined bacteriologically and parasitologically to investigate the causative agent. The disease was diagnosed as bovine coccidiosis caused by Eimeria zurnii based on the detection of $o{\ddot{o}}cysts$ and one of cattle was infected E. bukidnonensis, too.

  • 선천성 기관지 폐쇄증은 단순촬영에서 폐 결절로 보여 악성 종양으로 오인될 수 있다. 그러나 흉부단순촬영과 특히 전산화단층촬영에서는 늘어난 기관지 내의 점액고착, 구역 과팽창 등이 특징적으로 보여 더 이상의 침습적 검사 없이 선천성 기관지 폐쇄증으로 진단할 수 있다.

  • In a preliminary screening of the plant extracts for the antigastritic action in rats, the extract of Aralia elata(Araliaceae) showed positive activity in HCI plus ethanol induced gastric lesion. Systematic fractions with hexane, chloroform, ethyl acetate and butanol resulted in the most patent activity with the butanol fraction: This butanol fraction at the oral dose of 200 mg/kg exhibited significant inhibition of absolute alcohol induced gastric lesion which was more potent than 100 mg/kg of cimetidine and had significant stimulation of mucus secretion. The butanol fraction showed significant decreases in the ulcer indices of Shay ulcers and inhibition of gastric juice secretion with acid output in pylorus-ligated stomachs of rats. It also suppressed the acetic acid induced gastric ulcer. These results might suggest that the butanol fraction had inhibitory action in gastric lesion and ulceration through inhibition of gastric acid secretion and stimulation of mucin secretion in the stomachs of rats.

  • To establish a protocol of estrus induction and synchronization in European mouflon, we performed artificial insemination using frozen-thawed semen and exogenous hormones. CIDR was inserted into vaginas of four mouflons for 16 days. A day before removal of CIDR, PG 600 was injected intramuscularly. $PGF_2{\alpha}$ was injected when removing CIDR. Artificial insemination was cervically conducted with injecting LHRH 48 hours after CIDR withdrawal. Even though no pregnancy was confirmed, estrous signs were notified like open cervix, congestion of vaginal wall and discharge of cervical mucus. Further research in the wild sheep would be needed for development of artificial breeding methods and advancing sustainability of domestic zoos.

  • Curschmann's spirals morphologically similar to those seen in sputum were found in cervico-vaginal smears of six patients ranged from 28 to 40 years of age, during 18 months from January. 1985 to June 1986. The prevalence was 1 in 2147 smears in that period. All of them had gynecologic disorders without systemic effect such as chronic cervictis in three, leiomyoma in one, pelvic inflammatory disorder in one, and primary infertility in one. The Curshmann's spirals in the smear showed varying degrees of maturation from wavy incipient ones to highly celled mature ones, admixed with thick mucinous back-ground, suggesting of their production in the uterine cervix itself. Also the recent history of undergone cryocautery, electrocautery or parturition suggest its production in the endocervical gland due to mechanical obstruction and/or change in biochemical composition of mucus.

  • In this study, we intended to get a preliminary data for establishing rat tracheal surface epithelial(RTSE) cell culture system as an experimental model for physiology and pharmacology of tracheal epithelial cells. Primary culture on the membrane support and application of the air-liquid interface system at the level of cell layer were performed. The cell growth rate and mucin production rate were measured according to the days in culture. The results were as follows: this culture system was found to manifest mucocilliary differentiation of rat tracheal epithelial cells, the cells were confluent and the quantity of produced and released mucin was highest on culture day 9, the mucin was mainly released to the apical side and tbe free $^3{H}$-glucosamine which was not incorporated to process of synthesis of mucin was left on the basolateral side. Taken together, we suggest that air-liquid interface culture system can be used as a substitute for immersion culture system and as an experimental model for in vivo mucus-hypersecretory diseases.
