以水稻雌性不育材料FS-1为试验材料,采用石蜡连续切片技术对FS-1及其亲本藤坂5号幼穗发育中期的胚囊进行观察,结果表明:(1)亲本的胚囊都能正常发育分化,成为功能健全的雌配子体,而FS-1的胚囊却普遍发生败育,在胚囊原来的区域充满了胚囊残迹和解体的珠心细胞。(2)败育基本上发生在功能大孢子发生期,近合点端的大孢子和珠孔端的三个大孢子都发生解体,实验中未发现二核、四核或八核的败育胚囊,我们初步认为,FS-1胚囊败育发生在功能大孢子发生期。

A case of chronic pancreatitis in which endoscopic ultrasonography was effective in the diagnosis of a pseudoaneurysm

World Journal of Gastrointestinal Endoscopy 2012年第7期4卷 335-338页

作者： Kazuhiro Fukatsu Kazuki Ueda Hiroki Maeda Yasunobu Yamashita Masahiro Itonaga Yoshiyuki Mori Kosaku Moribata Naoki Shingaki Hisanobu Deguchi Shotaro Enomoto Izumi Inoue Takao Maekita Mikitaka Iguchi Hideyuki Tamai Jun kato masao Ichinose Second Department of Internal Medicine Wakayama Medical University811-1 Kimiidera Wakayama City Wakayama 641-0012 Japan

Endoscopic ultrasonography (EUS) was performed on a patient being treated for chronic pancreatitis because a submucosal tumor was observed in the stomach during gastrointestinal endoscopy. As internal pulsa- tile blood flow on Doppler was present, the diagnosis of an aneurysm was made. The pseudoaneurysm of the left gastric artery was embolized with histoacryl and lipiodol and the splenic artery was embolized with coils at the location of the pseudoaneurysm to prevent hemorrhage. Follow up EUS confirmed the cessation of blood flow from the pseudoaneurysm. Clinicians encountering a gastric submucosal tumor-like protrusion in a patient with chronic pancreatitis should use EUS to investigate the possibility of a pseudoaneurysm, which must be treated as quickly as possible once identified.

Usefulness of continuous suction mouthpiece during esophagogastroduodenoscopy: A single-center, prospective,randomized study

AIM: To develop a new continuous suction mouthpiece(CSM) and evaluate its usefulness for screening esophagogastroduodenoscopy(EGD).METHODS: A total of 196 patients who were scheduled to undergo screening EGD were assigned to one of two groups: a group using the CSM and a group using a conventional mouthpiece. Extent of salivary flow,frequency of saliva suction, number of choking episodesduring the examination, and incidence of aspiration pneumonia after the examination were evaluated and compared between the two groups. Adverse events during and after EGD were also examined. In addition, the oral cavity was meticulously examined after the ***: The same number of patients was randomly allocated to each group. There were no significant differences between the two groups in sex, age,biopsy procedure, duration of procedure and depth of sedation. Aspiration pneumonia and other significant adverse events were not observed in either group. The grade of extent of salivary flow was significantly lower in patients with the CSM than in patients with the conventional mouthpiece(P < 0.001). Although there was no significant difference, less frequent suctioning and fewer choking episodes were observed in patients with the CSM than in patients with the conventional mouthpiece(P = 0.082 and P = 0.084, respectively). In addition, there were no patients in the CSM group who required saliva suctioning during the ***: Use of the CSM during screening EGD can reduce the extent of salivary flow. The device is expected to reduce complications and contamination with saliva.

World Journal of Gastrointestinal Endoscopy 2011年第8期3卷 162-170页

AIM: To compare the diagnostic performances of transnasal and standard transoral esophagogastroduodenoscopy (EGD) in gastric cancer screening of asymptomatic healthy subjects. METHODS: Between January 2006 and March 2010, atotal of 3324 subjects underwent examination of the upper gastrointestinal tract by EGD for cancer screening, with 1382 subjects (41.6%) screened by transnasal EGD and the remaining 1942 subjects (58.4%) by standard transoral EGD. Clinical profiles of the screened subjects, detection rates of gastric neoplasia and histopathology of the detected neoplasias were compared between groups according to the stage of Helicobacter pylori (H. pylori )-related chronic gastritis. RESULTS: Clinical profiles of subjects did not differ significantly between the two EGD groups, except that there were significantly more men in the transnasal EGD group. During the study period, 55 cases of gastric mucosal neoplasias were detected. Of these, 23 cases were detected by transnasal EGD and 32 cases by standard transoral EGD. The detection rate for gastric mucosal neoplasia in the transnasal EGD group was thus 1.66%, compared to 1.65% in the standard transoral EGD group, with no significant difference between the two groups. Detection rates using the two endoscopies were likewise comparable, regardless of H. pylori infection. However, detection rates when screening subjects without extensive chronic atrophic gastritis (CAG) were significantly higher with standard transoral EGD (0.70%) than with transnasal EGD (0.12%, P < 0.05). In particular, standard transoral EGD was far better for detecting neoplasia in subjects with H. pylorirelated non-atrophic gastritis, with a detection rate of 3.11% compared to 0.53% using transnasal EGD (P < 0.05). In the screening of subjects with extensive CAG, no significant differences in detection of neoplasia were evident between the two endoscopies, although the mean size of detected cancers was significantly smaller and the percent
