Hemodynamic effects of acute carbon monoxide poisoning were studied in mongrel dogs. In this study dogs were divided into two groups, namely the control and the experimental. Carbon monoxide poisoning in the experimental group was induced by the breathing of about 2% CO gas mixture for 15 minutes, and this group was further divided into two, in which the arterial CO saturation was below 50%, 30 minutes after the CO gas breathing for 15 minutes (group I) and above 50% (group II). The heart rate was markedly decreased in the both experimental groups, particularly in the group I. The cardiac index showed a relative increase in the group II compared to that of the control, and the stroke volume also showed a relative increase in the both experimental groups, being more marked in the group II. Thus the increase in the cardiac output in the group II was caused mainly by the increase in the stroke volume. The femoral artery mean pressure was decreased both in the control and the experimental groups, being more marked in the group II. There was no appreciable difference in the femoral venous pressure between the control and the experimental groups. The total peripheral resistance was decreased 30 minutes after CO gas breathing in both experimental groups, particularly in the Group II. The pulmonary artery mean pressure showed a decrease in the control and the experimental groups, and there was no prarticular difference between these two groups. The changes in the total pulmonary resistance were rather similar to those of the total peripheral resistance.

Patients treated by extracorporeal shock wave lithotripsy are usually evaluated by excretory urography within 1 month after treatment to determine the clearance of stone debris and rule out asymptomatic obstruction. In an attempt to obtain more precise functional information, we used 99m-Tc-DTPA renal scan as the initial follow-up study after ESWL in 10 patients. GFR checked by renal scan shows no difference in pre and post ESWL. Our experience suggests that follow up after ESWL by radionuclide renal imaging studies provides specific functional information and also particular value in the management of patients with obstructing stone debris and diminished renal function. Radionuclide renal imaging studies may also reveal unexpected obstruction and functional impairment after ESWL of stones, and is recommended as routine follow-up study after ESWL.

Polycystic ovary syndrome is characterized by symptoms of oligomenorrhea, amenorrhea, infertility, hirsutism and obesity. It is known that the women with such diseases would have higher risks to coronary heart diseases, hypertension, DM and endometrial cancer later on, Known risk factors of endometrial cancer are nullipara, late menopause, obesity, DM, unopposed estrogen, tamoxifen treatment, and atypical endometrial hyperplasia ect. 75% of endometrial cancer occurs in age over 50 and 4% of endometrial cancer occurs in age under 40. Particulary endometrial cancer concurrent polycystic ovary syndrome occurs usually in people under age 40 and is commonly well differentiated cell type and is related to good prognosis. We experienced a case of endometrial cancer with polycystic ovary syndrome, who was early dignosed, presented with infertility and got an operation in our hospital, and report this case with a brief review of literature.

OBJECTIVE: A novel inhibitor of apoptosis, survivin, seems to be involved in critical steps of cancer onset and progression, and associated with unfavorable clinical outcome. We investigated the expression of survivin in patients with cervical intraepithelial neoplasm and uterine cervical cancer to determine whether survivin indicates the poor prognosis or not. METHODS: The study included 14 cases of cervical intraepithelial neoplasia grade III, 53 cases of invasive uterine cervical squamous cell carcinoma. Immunohistochemical stain and western blot was performed with antihuman survivin antibody. RESULTS: Survivin was highly expressed in CIN III and cervical cancer group than normal control group (p<0.05). Significant survivin expression was noted in cancer patients with lesion size >or=4 cm, lymphovascular invasion, elevated SCC Ag. level, and nonresponse to initial therapy. As the clinical stage goes up, survivin expression had a tendency to increase but there was no statistical significance (p=0.081). No association was noted between survivin expression and survival rate (p=0.1011). CONCLUSION: This results suggest that survivin expression may provide prognostic information and could represent a possible new marker of prognosis in uterine cervical squamous cell carcinoma patients.

OBJECTIVES: SCC Ag(Squamous cell carcinoma antigen) is so far the most useful tumor marker in assisting clinical diagnosis of cervical cancer and follow-up after therapy. Elevated levels of cytokeratin 19-fragments(CYFRA 21-1) have recently been detected in large proportion of patients with non small cell cancer of the lung, and in particular those with squamous cell carcinoma. This study is to assess the clinical efficacy of CYFRA 21-1 with SCC Ag as the clinicopathologic parameter in cervical cancer. METHOD: Retrospective analysis of the serum tumor markers CYFRA 21-1 & SCC Ag in eighty cervical cancer patients was performed. RESULTS: Cut off values for SCC Ag & CYFRA 21-1 were 1.94 ng/ml, 3.11 ng/ml respectively. Using the cut-off point, the sensitivity, specificity, positive predictive value(PPV), and negative predictive value(NPV) of serum SCC were 55, 95, 97, 46%, respectively. Serum CYFRA 21-1 showed a sensitivity of 45%, specificity of 91%, PPV of 87%, and NPV of 55%. The combination of SCC and CYFRA 21-1 increased the sensitivity to 62%, with a specificity, PPV, and NPV of 72, 75, 58%. Serum levels of both markers were compared with tumor stage, lesion size and were significantly related. In FIGO stage Ib-IIa, the serum levels of SCC Ag & CYFRA were 2.2+/-3.9, 2.5+/-3.6 ng/ml and in FIGO stage IIb-IV, 12.2+/-15.2, 10.8+/-11.2 ng/ml. In < or =4cm of lesion size the serum levels of SCC Ag & CYFRA were 3.3+/-9.0, 4.5+/-7.6 ng/ml and in >4cm of lesion size, 11.8+/-11.9, 7.7+/-9.3 ng/ml. CONCLUSION: These data seems to show that serum CYFRA 21-1 may be of additional value in assessing the state of disease in some patients with cervical cancer. The prediction of recurrent cervical cancer with SCC Ag were improved by the combination with CYFRA 21-1 but further investigation is needed.

BACKGROUND: An intravenous infusion of lidocaine has been used on numerous occasions to produce analgesia in neuropathic pain. In the cases of failed back surgery syndrom, the pain generated as result of abnormal impulse from the dorsal root ganglion and spinal cord, for instance as a result of nerve injury may be particularly sensitive to lidocaine. The aim of the present study was to identify the effects of IV lidocaine on neuropathic pain items of FBSS. METHODS: The study was a randomized, prospective, double-blinded, crossover study involving eighteen patients with failed back surgery syndrome. The treatments were: 0.9% normal saline, lidocaine 1 mg/kg in 500 ml normal saline, and lidocaine 5 mg/kg in 500 ml normal saline over 60 minutes. The patients underwent infusions on three different appointments, at least two weeks apart. Thus all patients received all 3 treatments. Pain measurement was taken by visual analogue scale (VAS), and neuropathic pain questionnaire. RESULTS: Both lidocaine (1 mg/kg, 5 mg/kg) and placebo significantly reduced the intense, sharp, hot, dull, cold, sensitivity, itchy, unpleasant, deep and superficial of pain. The amount of change was not significantly different among either of the lidocaine and placebo, or among the lidocaine treatments themselves, for any of the pain responses, except sharp, dull, cold, unpleasant, and deep pain. And VAS was decreased during infusion in all 3 group and there were no difference among groups. CONCLUSIONS: This study shows that 1 mg/kg, or 5 mg/kg of IV lidocaine, and palcebo was effective in patients with neuropathic pain attributable to FBSS, but effect of licoaine did not differ from placebo saline.
