Estimation of the Temperature and Humidity of an Underground Air Current

In planning underground air conditioning either by ventilation or by equipping with a cooler, it is essential to estimate the underground air temperature and humidity attained after the ventilation or the equipment is completed. The strict calculation of them, however, is very difficult and troublesome, because many factors, known and unknown, are involved. The authors have studied, for several years, the fundamental problems in connection with the temperature and humidity of an underground air current. The present paper describes the method of estimation, proposed by them, in which the evaporation of water on the wall surface, one of the factors having a great influence on the air temperature, is taken into account. The theory of this estimation stands on the fact that the change in temperature of an air current becomes very small after a sufficient period of time, say a year, from the beginning of ventilation, and that the heat quantity transmitted to an air current from rock across a unit area in a unit time is approximately proportional to the heat conductivity of rock and the difference between the undisturbed earth temperature and the air temperature

The Pretreatment of Maximum Standardized Uptake Values (SUVmax) of the Primary Tumor Is Predictor for Poor Prognosis for Patients with Epithelial Ovarian Cancer

The purpose of this study was to evaluate prognostic factors for epithelial ovarian cancer. We found that the pretreatment values of maximum standardized uptake (SUVmax) of the primary tumor by positron emission tomography/computed tomography (PET/CT), tumor marker CA125 and C-reactive protein (CRP) were correlated with clinical characteristics and prognosis for such patients. The clinical parameters and prognoses and their correlations with SUVmax of primary tumor, CA125 and CRP were examined for 51 patients with primary ovarian cancer. The SUVmax of the primary tumor had a statistically significant association with stage (p＝0.010) and histology (p＝0.001). CA125 was significant associated with stage (p＝0.011), histology (p＝0.005) and lymph node metastasis (p＝0.025). CRP was also significantly associated with stage (p＝0.049). Disease-free survival rates of patients exhibiting a high SUVmax, CA125 and CRP were significantly lower than those exhibiting a low SUVmax, CA125 and CRP levels (p＝0.008, 0.034, and 0.037, respectively). Furthermore, overall survival rates of patients exhibiting a high SUVmax were significantly lower than those exhibiting a low SUVmax (p＝0.049).The high SUVmax of primary tumor is an important factor for identifying ovarian cancer patients with a predictor for poor prognosis

気管支喘息の臨床分類とその細胞性および液性因子の特徴

Characteristics of each asthma type classified by clinical symptoms and　findings were studied in 72 patients with bronchial asthma. 1. Ventilatory function tests showed that the values of % MMF, % V(50) and % V(25) were significantly lower in patients with bronchiolar obstruction (type II) compared to the values of those with simple bronchoconstriction type (type Ia) and those with bronchoconstriction + hypersecretion (type Ib). 2. The proportion of neutrophils in bronchoalveolar lavage (BAL) fluid was significantly higher in type II than in type Ia and type Ib. Several　patients with type Ib showed higher proportion of BAL eosinophils. 3. The release of LTC(4) from leucocytes was significantly lower in type II compared with type Ia and type Ib. There was no significant difference in the release of histamine and LTB(4) among the three asthma types.気管支喘息72例を対象に,その臨床病態の特徴を,気道炎症性の細胞および化学伝達物質の観察により検討した｡1.気道反応の特徴を換気機能の面から検討すると,II細気管支閉塞型において,MMF,V(50)やV(25)などの小ないし細気管支領域の換気障害を示すパラメーターの値は,Ia型,Ib型に比べ 有意の低下を示した｡2.気道細胞反応では,II型において,他の臨床病型に比べ,BAL液中好中球の出現頻度の有意の増加が観察された(Ia, p<0.001 ; Ib, p<0.01)｡好酸球の出現頻度は,Ib過分泌型において著しい増加傾向を示す症例が見られたが,その平均出現頻度には3病型間に有意の差は見られなかった｡3.好中球からのメジェー夕ー遊離では,ヒスタミン遊離は,Ia単純性気管支撃縮型において最も高い値が示されたが,推計学的には3病型間に有意の差は見られなかった｡ロイコトリエンC(4)では,Ia型においてII型に比べ有意に高い遊離が観察された(p<0.05)｡ロイコトリエンB(4)遊離には,3病型間に差は見られなかった

Immunohistochemical Evaluation of Insulin-like Growth Factor I Receptor Status in Cervical Cancer Specimens

The insulin-like growth factor I receptor (IGF-IR) is exceptionally overexpressed in many cervicalcancer-derived cell lines. It is postulated that a decrease of p53 protein levels due to human papillomavirus (HPV) infection may contribute to the up-regulation of IGF-IR expression in cervical cancer cells because transcription of IGF-IR is strictly down-regulated by p53. To evaluate this fact in clinical cervical cancer specimens, we checked the expression levels and activated status of IGF-IR by immunohistochemistry. Formalin-fixed and paraffin-embedded specimens obtained by conization or hysterectomy were stained with anti-IGF-IR and with an antibody recognizing phosphorylated tyrosine at its c-terminus. The expression levels of IGF-IR were significantly high in cervical intraepithelial neoplasia (CIN) III and invasive cancer specimens. Phosphorylation of IGF-IR was promoted in all CIN and invasive cancer specimens, and its intensity was related to the promotion of lesions. Interestingly, IGF-IR overexpression was missing in the basal layer of CIN I and II lesions, whereas it was evenly distributed in CIN III and invasive cancer lesions. This IGF-IR overexpression pattern may be utilized in the diagnosis of HPV infection status in CIN lesions.</p

Cutaneous sarcoidosis : Clinical features and management

1976年から1996年に岡山大学第2内科を受診したサルコイドーシス255例のうち,65例(71病変)の皮膚サルコイドーシス(皮膚サ症)について,臨床経過,臨床検査成績,胸部病変との関連,予後について検討した｡皮膚サ症患者の年齢は18歳から77歳で中央値は51歳であった｡女性例が42例(65%)と多 く,特に50歳代女性に43%と最も高率であった｡皮膚病型では結節型33例,皮下型16例,び慢浸潤型3例,局面型6例,結節性紅斑様皮疹3例,苔癬様型1例,瘢痕浸潤9例であった｡皮膚サ症では非皮膚サ症に比して気管支肺胞洗浄液中リンパ球の低率が見られたが,その他の臨床成績に差は認められなかった｡皮膚病型別に検討すると,局面型,び慢浸潤型では気管支肺胞洗浄液中リンパ球CD4/CD8比は高く,3年後の皮膚および肺病変の残存率は高かった｡一方皮下型ではCD4/CD8比は低く皮膚,肺病変の残存率も低かった｡Of 255 patients with clinical and histologic evidence of sarcoidosis, 65 (25percent) presented with various cutaneous manifestations of the disease. Cutaneous sarcoid patients were 42 women and 23 men ranging from 18 to 77 years in age. The skin lesions have included nodular infiltration in 33 patients, subcutaneous tumor in 16 patients, lupus pernio in 3, annual plaques in 6, erythema nodosum-like eruption in 3, lichinoid in 1, and scars in 9. There was no correlation between the presence of cutaneous lesions and chest radiolographic stages, abnormal pulmonary gallium uptake, cell differenciations of bronchoalveolar lavages and serum angiotensin converting enzyme activities. Forty-six patients followed for at least 3 years to determine the course of the disease. Subcutaneous tumors tended to heal within 3 years, while lupus pernio and plaque lesions were likely to have a protracted course
