There are many procedures which treat pulmonary tuberculosis. Pneumoperitoneum of those which was begun by Banyai in 1934 is considered effective collapse therapy economically and socially in Korea. The author had studied 30 patients receiving pneumoperitoneum and/or chemotherapy who were moderatedly advanced pulmonary tuberculosis with positive sputum to AFB stain between Apt. 1, 1976 and Oct. 1, 1976. An attempt is to clarify the effects of pneumoperitoneum with chemotherapy [A group: 20 patients] in contrast with chemotherapy alone [B group: 10 patients] for 6 months. The results obtained were as follows: 1] All both groups showed the diminished pulmonary cavity size, but the effect of A group is prominent as 74% rather than 39% of B group. 2] Sputum conversion ratio is 55% in A group, and 20% in B group. 3] In Korea, the moderate amount of air is 1500cc in men, 1000cc in women. 4] Although pneumoperitoneum is in old hands, it is a relatively safe procedure, well tolerated, free from serious complications. 5] The advantages of pneumoperitoneum are evident in the treatment of bilateral lesion, with or without cavity, not too far advanced.

50세 여자가 전흉부의 통증을 주소로 내원하였다. 흉부단층촬영에서 우상엽을 침범하고 있는 전종격동의 종괴가 발견되었으며, 수술로서 완전절제하였다. 조직검사에서 악성 흑색종을 진단할 수 있었고, 원발병소의 가능성이 있는 피부, 구강, 안저, 비강, 직장, 항문, 질 등을 각각의 전문의에게 검사를 받았으나 이상소견이 없었다. 원발병소가 자연적으로 소멸된 경우가 아니라면 종격동에 원발한 악성 흑색종이라고 생각된다. 종격동에 발생하는 악성 흑색종은 아주 드문 질환으로 세계적으로 8례만이 보고되고 있고, 한국에서는 아직 예가 없기에 보고하는 바이다.

Antimicrobial activity of GL (the aqueous extract from the carpophores of Ganoderma lucidum ($F_RK_{KARST}$) was tested in vitro aginst Gram positive and Gram negative bacteria by serial broth dilution method, and the antimicrobial activity was expressed by minimal inhibitory concentration (MIC). Among fifteeen species of bacteria tested, the natimicrobial activity of GL was of antimicrobial combinations of GL with four kinds of antibiotics (ampicilin, cefazolin, oxytet-racycline and chloramphenicol), the fractional inhibitory concentraction index (FICI) was determined by checkerboard assy for each stain. The antimicrobial combinations of GL with four antibiotics resulted in additive effect in most instances, synergism in two instances, and antagonism in two instances. Synergism was obversed when GL was combined with cefazolin against Bacillus subtilis and Klebsiella oxytoca.

A 38 years old man had been treated as a pulmonary tuberculosis by the positive result of acid fast stain of bronchial washing from the focal infiltrative lesion at left lower lobe. On radiologic examination after one year treatment, there was an aggravation of lesion at left lower lobe with moderate amount of pleural effusion at the same side. After 11 weeks, follow up chest film disclosed bilateral pleural effusion. The pleural fluid of both side was pus in gross appearance with low pH, high LDH, low glucose and high protein. Pleurodectomy was performed to remove the loculated empyema with the thickened pleura of right thorax. This pleuro-pulmonary lesion can be easily misdiagnosed as a tuberculous lesion if it is not taken into consideration as a possible diagnosis.

In order to study the mechanism of follicle growth and maturation, and also to supplement the criteria identifying the follicle state of normal of atretic, the histochemical investigation on the ovarian follicles according to the ovarian cycle of mouse, rat and pig has been done. The intercellular space of granulosa cells, especailly Call-Exner body, and follicular fluid in the antrum showed positive to PAS, and blue stain by trichrome dye. The resutls suggest that the mucous polysaccharide was synthesized by the granulosa cells, and secreted into the antrum through Call-Exner body so as to be the components of the follicular fluid as the follicles proceeded to growth and maturation. The further the follicles proceeded to atresia the more densely their theca externa were stained blue by follicles proceeded to atresia the more densely their theca externa were stained blue by trichrome dye, and the more densely the granulosa cells were stained red by oil red 0 dye. Therefore, these staining methods can be applied to the criteria identifying the follicle atresia.

Helicobacter pylori (H. pylori) infection is common in korea and high incidence at gastric ulcer and duodenal ulcer. $^{14}C-urea$ breath test ($^{14}C-UBT$) is regarded as a highly reliable and non-invasive method for the diagnosis of H. pylori infection. The purpose of this study was to evaluate the diagnositc performance of a new and rapid $^{14}C-UBT$, which was equipped with Geiger-Muller counter and compared the results with those obtained by gastroduodenoscopic biopsies (GBx). One hundred sixty-eight patients (M : F = 118 : 50) underwent $^{14}C-UBT$, rapid urease test (CLO test), and GBx. The results of $^{14}C-UBT$ were classified as positive (>50 cpm), borderline (25$^{14}C-UBT$ or CLO test results with GBx as a glod standard. In the assessment of the presence of H. pylori infection, the $^{14}C-UBT$ global performance yielded positive predictive value, negative predictive value and accuracy of 93.3% and 83.3%, respectively. However, the CLO test had performance yielded positive predictive value, negative predictive value and accuracy of 76.9%, 50.0%, respectively. In this study $^{14}C-UBT$ is a highly accurate, simple and non-invasive method or the diagnosis of follow up H. pylori infection.

Background : Mesenchymal stem cells (MSCs) are present in most of the tissue matrix, taking part in their regeneration when injury or damage occurs. The aim of this study was to investigate the presence of cells with pluripotential characteristics in human subchondral bone and the capacity of these cells to differentiate to osteoblast. Methods : Human subchondral bone were digested with collagenase. Isolated cells were cultured with a-MEM, 15% FBS, 10-8M dexamethasone and 50 ng/mL ascoric acid. Cells from 0 day(isolated cells), 7 day (first subculture) and 14 days (third subculture) were used to carry out phenotypic characterization experiments flowcytometry analysis with 11 monoclonal antibodies) and osteogenic differentiation experiments. Osteogenic differentiation of cells was assessment by quantification of bone extracellular matrix components by following analysis: alkaline phosphatase(ALP) stains to detect ALP activity, RT-PCR and western blot to detect osteocalcin (OCN), osteopontin (OPN) and type I collagen(Col I), and Alizarin red stains to detect calcium deposition. Results : Flowcytometry analyses showed that in our population more than 98% of cells were positive for MSC markers: SH-2(CD105, 99%), CD29 (95%), CD73 (95%). Cells were negative for hematopoietic markers (CD11b, CD34, and CD45). Furthermore, cells showed positive stain to multipotent markers such as CDl17 (c-kit) (15.1%), and CD166 (74.9%), and cell adhesion molecules such as CD54 (78.1%) and CD106 (63.5%). The osteogenic specific marker analyses showed that the culture of these cells for 7 and 14 days stimulates ALP, OCN, OPN and Col I synthesis by RT-PCR and Western blot analysis. Also, after 14 days in the culture of MSCs induces mineralization by Arizarin red stain. Conclusion : In this work, we demonstrated a new and efficient method for osteoblastic differentiation of human subchondral bone stem cells. As MSCs takes part in reparative processes of adult tissues, these cells could play an important role in osteogenesis.

Objectives : This study was carried out to compare the effects of Eejin-tang, Hyangsaeejin-tang and Naeso-san extracts on indomethacin-induced gastric mucosal lesions in mice. Methods : Experimental mice were divided into six groups. The normal group had no gastro-inflammation. In the control group, gastro-inflammation was elicited by indomethacin. Misoprostol, Eejin-tang, Hyangsaeejin-tang and Naeso-san group were those in which misoprostol, Eejin-tang extract, Hyangsaeejin-tang extract and Naeso-san extract were administered after gastro-inflammation is elicited. This study examined the anti-inflammation effects and distribution of mucus secreting cells, zonula occludin-1 (ZO-1), heat shock protein (HSP) 70, periodic acid-schiff reaction stain (PAS), peanut agglutinin (PNA), cyclooxygenase-1 (COX-1), 5-bromo-2'-deoxyuridine (BrdU), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-${\kappa}B$) p65, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Results : 1. The hemorrhagic erosion and damaged mucus secreting cell, the positive reaction HSP70 increased in the control group, but decreased in the Eejin-tang, Hyangsaeejin-tang and Naeso-san groups. 2. The positive reaction of ZO-1, PAS, PNA, COX-1 and BrdU decreased in the control group, but increased in the Eejin-tang, Hyangsaeejin-tang and Naeso-san groups. 3. The positive reaction of NF-${\kappa}B$ p65, iNOS and COX-2 increased in the control group, but decreased in the Eejin-tang, Hyangsaeejin-tang and Naeso-san groups. Conclusions : Among the three extracts, the effects were in the order of Naeso-san, Hyangsaeejin-tang and Eejin-tang group, Naeso-san being the most effective.
