Effects of Ginkgo biloba extract (EGb 761) on the anti-pulmonary hypertensive action of enalapril were evaluated in rats. Pulmonary hypertension was induced by monocrotaline treatment (60mg/kg, i.p.) in normotensive rats. In the systolic pulmonary artery pressure, the control group was 33$\pm$2 mmHg, comparing to the normal group of 19$\pm$1 mmHg. That of enalapril group(20mg/kg/day, p.o.) was 26$\pm$2 mmHg. In the isolated lung preparation, acetylcholine, which was endothelium dependent vasodilator, induced the decrease of pulmonary artery perfusion pressure(-2.0$\pm$0.7 mmHg) in normal group, but the increase of that of 3.4$\pm$0.6 and 3.0$\pm$0.9 mmHg in control and enalapril group, respectively. And that of the combined group was -0.5$\pm$0.2 mmHg. In the isolated pulmonary artery, acetylcholine(10-5M) induced the relaxation of 65$\pm$6% in normal group, but 15 and 8% in control and enalapril group, respectively. And that of the combined group was resulted 55$\pm$2%. These results suggested that co-administration of Ginkgo biloba extract(EGb 761) potentiated the anti-pulmonary hypertensive effects of enalapril through the increase of pulmonary vasodilation due to the protection of endothelial cell by antioxidant action of Ginkgo biloba extract (EGb 761).

To investigate the endothelial dependence of angiotensin II(A II)-induced responses in the systemic and pulmonary arterial system of acute renal hypertensive rats of 2-kidney, 1-ligation type (RHRs), A II-induced vasocontractile and pressor effects were evaluated in isolated arteries and in vivo, respectively. A II dose-dependently contracted intact thoracic aorta and pulmonary artery (E$_{max}$:40% at 10$^{-7}$M and 80% at 3$\times$10 $^{-8}$M, respectively) from normotensive rats(NRs), which was significantly increased by removal of endothelial cells or pretreatment with EDRF inhibitors. In NRs, A II increased mean systemic and pulmonary arterial pressure(33 and 5.6mmHg at 0.1 $\mu\textrm{g}$/kg, respectively), the effect being significantly increased (P<0.01) by L-NAME(30mg/kg, i.v.). However, A II-induced contraction of intact thoracic aorta and pulmonary artery(E$_{max}$: 33% at 10$^{-7}$M and 93% at 3$\times$10$^{-8}$M, respectively) from RHRs were not changed after endothelial function was disrupted as above; similarly, pressor effects of A II on the systemic and pulmonary arterial pressure in RHRs did not altered by L-NAME. A II tachyphylactic responses for intact thoracic aorta from NRs and RHRs(65 and 87% at 10$^{-8}$M, respectively) were greater than those for pulmonary artery(19 and 19% at 10$^{-8}$M, respectively). Distruption of endothelial function significantly (P<0.01) depressed A II tachyphylaxis for thoracic aorta, but not for pulmonary artery. These results suggest that vascular reactivity to A II is not altered in RHRs, and it is greater for pulmonary arterial system than for systemic arterial system. A II reactivity is EDRF-dependent in both arterial systems of NRs, but EDRF-independent for RHRs. Finally, EDRF is one of the major factors underlying A II tachyphylaxis for thoracic aorta, but not for pulmonary artery.

Background: No consensus exists regarding whether volatile anesthetics are superior to intravenous anesthetics for reducing postoperative pulmonary complications (PPCs) in patients undergoing general anesthesia for surgery. Studies of this issue focused on anatomic pulmonary resection are lacking. This study compared the effects of total intravenous anesthesia (TIVA) versus volatile anesthesia on PPCs after anatomic pulmonary resection in patients with lung cancer. Methods: This retrospective study examined the medical records of patients with lung cancer who underwent lung resection at our center between January 2018 and October 2020. The primary outcome was the incidence of PPCs, which included prolonged air leak, pneumonia, acute respiratory distress syndrome, empyema, atelectasis requiring bronchofiberscopy (BFS), acute lung injury (ALI), bronchopleural fistula (BPF), pulmonary embolism, and pulmonary edema. Propensity score matching (PSM) was used to balance the 2 groups. In total, 579 anatomic pulmonary resection cases were included in the final analysis. Results: The analysis showed no statistically significant difference between the volatile anesthesia and TIVA groups in terms of PPCs, except for prolonged air leak. Neither of the groups showed atelectasis requiring BFS, ALI, BPF, pulmonary embolism, or pulmonary edema after PSM. However, the length of hospitalization, intensive care unit stay, and duration of chest tube indwelling were shorter in the TIVA group. Conclusion: Volatile anesthetics showed no superiority compared to TIVA in terms of PPCs after anatomical pulmonary resection in patients with lung cancer. Considering the advantages of each anesthetic modality, appropriate anesthetic modalities should be used in patients with different risk factors and situations.

Objective: Patients with chronic obstructive pulmonary disease (COPD) may experience reduced physical activity and quality of life (QoL) due to decreased pulmonary function. The purpose of this study was to investigate the level of pulmonary function, physical activity, and QoL of COPD patients. Design: Cross-sectional observational study. Methods: This study examined the published data of the Korea National Health and Nutrition Examination Survey in 2015-2019. Among 39,759 subjects who participated for 5 years, data from 151 patients diagnosed with COPD were analyzed separately. For the pulmonary function, the results of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV6, forced expiratory flow 25-75%, and peak expiratory flow were observed. Physical activity was identified as frequency and duration. For the QoL, EQ-5D-3L evaluation results were examined, and the frequency and index of the Korean version were investigated. Results: In pulmonary function, all variables were found to be lower than age and weighted matched normal values. COPD patients showed to perform very low levels of high/medium physical activity and sitting time was confirmed to be more than 8 hours a day. In QoL, it was found that the highest reporting rate of some problems was the "pain and discomfort" and "mobility". Conclusions: It was found that COPD patients showed that the prevalence of circulatory disease was relatively high, lowered pulmonary function, and QoL. These can be improved through regular physical activity, and it is thought that this can be achieved through optimization of pulmonary rehabilitation.

Carbohydrate antigen 19-9 (CA19-9) is a specific tumor marker of the biliary, pancreatic and gastrointestinal tracts. CA19-9 is occasionally elevated in serum in patiens with benign pulmonary diseases such as bronchiectasis, idiopathic interstitial pneumonia or collagen disease-associated pulmonary fibrosis. Intralobar pulmonary sequestration is an uncommon congenital lung anomaly. It is dissociated from the normal tracheobronchial tree and is supplied by an anomalous systemic artery. There have been some reports of elevation of CA19-9 in this lesion. We report a case of intralobar pulmonary sequestration with elevated serum CA19-9 in a 29-year-old man who was diagnosed with bronchiectasia of left lower lung field on general check up. He had no evidence of any malignant disease in pancreatobiliary or gastrointestinal tracts. Elevated serum CA19-9 level might be encountered with benign pulmonary disease such as pulmonary sequestration.

Antiphospholipid syndrome (APS) is an acquired systemic autoimmune disorder characterized by a combination of clinical criteria, including vascular thrombosis or pregnancy morbidity and elevated antiphospholipid antibody titers. It is one of the causes of deep vein thrombosis and pulmonary embolism that can be critical due to the mortality risk. Overall recurrence of thromboembolism is very low with adequate anticoagulation prophylaxis. The most effective treatment to prevent recurrent thrombosis is long-term anticoagulation. We report on a 17-year-old male with APS, who manifested blue toe syndrome, deep vein thrombosis, pulmonary thromboembolism, and cerebral infarction despite adequate long-term anticoagulation therapy.

It has been known which the pulmonary mycosis usually results from secondary invader of preexisting bronchopulmonary diseases, e.g. pulmonary tuberculosis, bronchiectasis, abscess, cysts, or pulmonary malignancy and as the predisposing factor appears to be concerned with long-term therapy of several antibiotics, steroids, or chemotherapeutic agents, etc. Recently, it has been interested rather the diagnosis and pathogenesis of then pulmonary mycosis than the treatment, especially because of some difficulty of the diagnosis. The authors experienced too cases of the pulmonary mycosis which were treated onc case medically, as moniliasis and the other surgically, as aspergillosis. There was noticed that our pulmonary moniliasis developed probably due to long-term therapy of antibiotics and aspergillosis resulted from secondary invader in the previous cyst of bronchiectasis.
