不洁的性自慰易引起阴道炎康医生: 我是一名未婚女青年,今年25岁。在去年国庆节那段时间,有两天出现了很强的性欲,于是我又出现了手淫的毛病。这次,我是将一些布头塞进阴道里去,当然也尝到了高潮时的快感。可是第二天,我就觉得小腹内有种不舒服的感觉。那个月的月经也没来,在10月中旬还流出了咖啡色的液体和白带状的东西。请问康医生,这是什么症状,我该怎么办? 柯柯豆(内蒙)不洁的性自慰易引起阴道炎康医生: 我是一名未婚女青年,今年25岁。在去年国庆节那段时间,有两天出现了很强的性欲,于是我又出现了手淫的毛病。这次,我是将一些布头塞进阴道里去,当然也尝到了高潮时的快感。可是第二天,我就觉得小腹内有种不舒服的感觉。那个月的月经也没来,在10月中旬还流出了咖啡色的液体和白带状的东西。请问康医生,这是什么症状,我该怎么办? 柯柯豆(内蒙)

Inhibitory effects of carbon dioxide insufflation on pneumoperitoneum and bowel distension after percutaneous endoscopic gastrostomy

AIM:To evaluate the inhibitory effects of carbon dioxide (CO2) insufflation on pneumoperitoneum and bowel distension after percutaneous endoscopic gastrostomy (PEG).METHODS:A total of 73 consecutive patients who were undergoing PEG were enrolled in our study.After eliminating 13 patients who fitted our exclusion criteria,60 patients were randomly assigned to either CO2 (30 patients) or air insufflation (30 patients) groups.PEG was performed by pull-through technique after threepoint fixation of the gastric wall to the abdominal wall using a gastropexy device.Arterial blood gas analysis was performed immediately before and after the procedure.Abdominal X-ray was performed at 10 min and at 24 h after PEG to assess the extent of bowel distension.Abdominal computed tomography was performed at 24 h after the procedure to detect the presence of pneumoperitoneum.The outcomes of PEG for 7 d postprocedure were also investigated.RESULTS:Among 30 patients each for the air and the CO2 groups,PEG could not be conducted in 2 patients of the CO2 group,thus they were excluded.Analyses of the remaining 58 patients showed that the patients' backgrounds were not significantly different between the two groups.The elevation values of arterial partial pressure of CO2 in the air group and the CO2 group were 2.67 mmHg and 3.32 mmHg,respectively (P = 0.408).The evaluation of bowel distension on abdominal X ray revealed a significant decrease of small bowel distension in the CO2 group compared to the air group (P < 0.001) at 10 min and 24 h after PEG,whereas there was no significant difference in large bowel distension between the two groups.Pneumoperitoneum was observed only in the air group but not in the CO2 group (P = 0.003).There were no obvious differences in the laboratory data and clinical outcomes after PEG between the two groups.CONCLUSION:There was no adverse event associated with CO2 insufflation.CO2 insufflation is considered to be safer and more comfortable for PEG patients because of the lower incidence of pneumoperitoneum and less distension of the small bowel.

In vivo Anticancer Activities of Benzophenone Semicarbazone against Ehrlich Ascites Carcinoma Cells in Swiss Albino Mice

Objective Benzophenone semicarbazone(BSC) was synthesized and characterized to identify compounds with anticancer activities. Methods Anticancer activities were studied against Ehrlich Ascites Carcinoma(EAC) cells in Swiss albino mice by monitoring parameters such as tumor weight measurement,survival time of tumor bearing mice,tumor cell growth inhibition,and so on.Some hematological parameters,such as red blood cells,white blood cells,and hemoglobin content,were also measured. Results The results showed that BSC has a positive effect against EAC cells.An assessment was conducted by comparing these results with those obtained using the standard drug bleomycin. Conclusions The BSC compound can be considered as a potent anticancer agent.
