Perioperative surgical stress makes various metabolic and endocrinologic changes that may influence the postoperative outcome. These changes, so-called, "surgical stress responses" ar hyperglycemia, lipolysis, negative nitrogen balance due to proteolysis, and changes in the hormonal secretion, e.g. increased release of ACTH, prolactin, cortisol, catecholamine, and so on. To prevent these stress responses, many studies reported some kinds of effective methods. In these study we used general anesthesia combined with epidural blockade with local anesthetic(bupivacaine) and narcotic(fentanyl) mixture via epidural catheter for the total abdominal hysterectomy and the postoperative pain control(group II). We measured serum prolactin and cortisol concentrations by time-resolved fluoroimmunoassay and glucose concentrations by routine glucose oxidase method and scored the degree of postoperative pain and compared the results with those of group I, given general anesthesia during surgery and nalbuphine intramuscular injection for postoperative pain control. The results were as follows. 1) Serum prolactin concentrations were increased during the operation in both groups. 2) Serum cortisol concentrations were increased during and after the operation in both groups but were normalized sooner in group II. 3) Serum glucose concentrations were increased during and after the operation but were normalized sooner in group IL 4) The three measurements showed significant differences between the two groups during and on the first postoperative day. 5) The pain scores were significantly lower in group II untill the third postoperative day. According to the results, we concluded that serum prolactin concentration could be as much valuable index to surgical stress response as serum cortisol concentration and that the method of epidural blockade combined with general anesthesia for the surgery and postoperative pain control via epidural route could prevent or alleviate the stress response more effectively.

PURPOSE: To demonstrate and evaluate the value of MRI findings of the TSH(Thyroid-Stimulating Hormone, TSH, Thyrotropin)-secreting pituitary adenoma. MATERIALS AND METHODS: The authors reviewed retrospectively the MR images of 4 patients with TSH-secreting pituiatary adenoma. Evaluation of the anatomical location, signal characteristics, enhancement patterns, size, shape and circunferential changes were made. RESULTS: No characteristic common MR findings in size, shape, signal intensity, and circumferential changes of TSH-secreting pituiatary adenoma waere observed among 4 cases(size; 5x7 mm to 10x11 mm, shape;ovoid to round, signal intensity;high in 1 case on T1 and T2WI, isosignal intensity in the other 3 cases, circumferential change; stalk deviation in 1 case, no stalk deviation in 3 cases). But, the tumors were centrally located at the anterior pituitary gland and showed relatively homogeneous signal intensity on MR images of all 4 patients. CONCLUSION: We conclude that centrally-located mass at the anterior pituitary gland with homogeneous signal intensity on MR image may be suggestive of the TSH-secreting pituitary adenoma, although the MR findings are not specific for the disease.

It is common to use semiclosed circle system for general anesthesia because of economy, easy controllability of humidity and temperature, less contamination of operating room with anesthetic gas etc, but in case of malfunction of unidirectional valve, inappropriate absorption of carbon dioxide,leakage or obstruction of circle system the patient may become fatal. During general anesthesia with newly purchased anesthesia machine(Ohmeda Modulus II plus) we experienced three cases of hypercarbia because of malfunction of expiratory valve which could not be easily found due to overlying PEEP valve.

Asthma and chronic obstructive pulmonary disease (COPD) are characterized by chronic airway inflammation resulting in airflow limitation. They include various phenotypes and endotypes in their disease entities. For that reason, they lack proper biomarkers and epoch-making progresses in treatment nowadays. Healthy airway has been believed to be sterile traditionally. However, with the help of nonculture sequencing techniques, researchers discovered that it is full of the commensal and symbiotic microbial flora. Therefore, microbiome has emerged as a possible biomarker and a clue to understand the pathogenesis of airway disease. Microbiome research in asthma has focused on the association between characteristics of microbiome, such as composition and diversity. However, now it refers to the role of microbiome, including Proteobacteria, in the development and pathogenesis of asthma and allergic diseases. Microbiome research in COPD has revealed its different composition according to the existence and severity of the disease. Also, differences in microbiome composition according to exacerbation state or specific treatment of COPD are reported. Therefore, many researchers pay attention to the possible role of microbiome as a biomarker or a treatment target in asthma and COPD. Herein, we review recent studies on microbiome research in asthma and COPD.

In an attempt to obtain evidence in the mechanism of stone formation, the effectiveness of Amiloride. a K-sparing diuretic known to act on the distal nephron. on the kidney with oxamide-induced urolithiasis was investigated. Futhermore. the influence of stone formation on the distribution of intrarenal blood flow and the effect of Amiloride on them were also studied. Most prominent derangements of renal function observed during stone formation were decreases of both C(PAH) and C(cr) indicating the curtailment in renal hemodynamics. The oxamide-treated kidney also responded to Amiloride with typical natriuresis and antikaluresis. in the same fashion with normal kidneys. The experiments in which the intrarenal blood flow distribution was measured by PAH-extraction technique raveled that mainly the cortical blood flow was curtailed, whereas non-cortical blood flow (medullary flow) did not change during oxamide-stone formation. Amiloride did not influence the intrarenal b100d flow distribution both in normal and oxamide kidneys. These observations suggest that oxamide-stone formation was initiated not by tubular necrosis produced by the toxic action of oxalate on the tubules, but rather by mechanical obstruction of the tubules.
