Corticosteroids are used in the treatment of many diseases; however, they also induce various side effects. Dexamethasone is one of the most potent corticosteroids, and it has been reported to induce the side effect of impaired salivary gland function. This study aimed to evaluate the effects of dexamethasone on mouse submandibular gland function to gain insight into the mechanism of dexamethasone-induced salivary hypofunction. The muscarinic agonist carbachol(CCh) induced salivary secretion and was not affected by short-term dexamethasone treatment but was decreased following long-term dexamethasone administration. The expression levels of the membrane proteins Na^+-K^+-2 Cl-cotransporter, transmembrane member 16 A, and aquaporin 5 were comparable between the control and long-term dexamethasone treatment groups. The CCh-induced increase in calcium concentration was significantly lower in the presence of extracellular Ca^(2+) in the long-term dexamethasone treatment group compared to that in the control group. Furthermore, CCh-induced salivation in the absence of extracellular Ca^(2+) and Ca^(2+) ionophore A23187-induced salivation was comparable between the control and long-term dexamethasone treatment ***, salivation induced by the Ca^(2+) -ATPase inhibitor thapsigargin was diminished in the long-term dexamethasone treatment group. In summary, these results demonstrate that short-term dexamethasone treatment did not impair salivary gland function, whereas long-term dexamethasone treatment diminished store-operated Ca^(2+) entry, resulting in hyposalivation in mouse submandibular glands.

Dopamine receptor D4 gene (DRD4) is associated with gazing toward humans in domestic dogs (<i>Canis familiaris</i>)

Open Journal of Animal Sciences 2013年第1期3卷 54-58页

Dogs show high social communicative ability in interactions with humans. We investigated the association between dogs’ social communicative behavior and the polymorphisms of a gene related to a neurotransmitter. We used an “unsolvable task”, in which an experimenter put a food reward into a container and closed it firmly so that dogs could not remove the reward. Human-directed gazing, possibly to request help, is a characteristic behavioral trait of dogs in such situations. The association between owner-directed gazing behavior in the unsolvable task and polymorphisms of three regions (exon1, exon3, intron2) in the dopamine receptor D4 gene (DRD4) was analyzed. We found that the genotype of DRD4 intron2 was significantly associated with the dogs’ gazing behavior. Dogs carrying shorter allele (P) looked at their owner more frequently, for longer, and earlier than dogs carrying longer allele (Q). This result suggests that polymorphism in DRD4 intron2 may affect social communication and cognition in dogs.

Laparoscopic and endoscopic cooperative surgery for gastric tumors: Perspective for actual practice and oncological benefits

World Journal of Gastrointestinal Oncology 2018年第11期10卷 381-397页

Laparoscopic and endoscopic cooperative surgery(LECS) is a surgical technique that combines laparoscopic partial gastrectomy and endoscopic submucosal dissection. LECS requires close collaboration between skilled laparoscopic surgeons and experienced endoscopists. For successful LECS, experience alone is not sufficient. Instead, familiarity with the characteristics of both laparoscopic surgery and endoscopic intervention is necessary to overcome various technical problems. LECS was developed mainly as a treatment for gastric submucosal tumors without epithelial lesions, including gastrointestinal stromal tumors(GISTs). Local gastric wall dissection without lymphadenectomy is adequate for the treatment of gastric GISTs. Compared with conventional simple wedge resection with a linear stapler, LECS can provide both optimal surgical margins and oncological benefit that result in functional preservation of the residual stomach. As technical characteristics, however, classic LECS involves intentional opening of the gastric wall, resulting in a risk of tumor dissemination with contamination by gastric juice. Therefore, several modified LECS techniques have been developed to av-oid even subtle tumor exposure. Furthermore, LECS for early gastric cancer has been attempted according tothe concept of sentinel lymph node dissection. LECS is a prospective treatment for GISTs and might become a future therapeutic option even for early gastric cancer. Interventional endoscopists and laparoscopic surgeons collaboratively explore curative resection. Simultaneous intraluminal approach with endoscopy allows surgeons to optimizes the resection area. LECS, not simple wedge resection, achieves minimally invasive treatment and allows for oncologically precise resection. We herein present detailed tips and pitfalls of LECS and discuss various technical considerations.

Laparoscopic appendectomy for acute appendicitis: How to discourage surgeons using inadequate therapy

World Journal of Gastroenterology 2017年第32期23卷 5849-5859页

Acute appendicitis(AA) develops in a progressive and irreversible manner, even if the clinical course of AA can be temporarily modified by intentional medications. Reliable and real-time diagnosis of AA can be made based on findings of the white blood cell count and enhanced computed tomography. Emergent laparoscopic appendectomy(LA) is considered as the first therapeutic choice for AA. Interval/delayed appendectomy at 6-12 wk after disease onset is considered as unsafe with a high recurrent rate during the waiting time. However, this technique may have some advantages for avoiding unnecessary extended resection in patients with an appendiceal mass. Nonoperative management of AA may be tolerated only in children. Postoperative complications increase according to the patient's factors, and temporal avoidance of emergent general anesthesia may be beneficial for high-risk patients. The surgeon's skill and cooperation of the hospital are important for successful LA. Delaying appendectomy for less than 24 h from diagnosis is safe. Additionally, a semi-elective manner(i.e., LA within 24 h after onset of symptoms) may be paradoxically acceptable, according to the factors of the patient, physician, and institution. Prompt LA is mandatory for AA. Fortunately, the Japanese government uses a universal health insurance system, which covers LA.

Laparoscopic cholecystectomy(LC) does not require advanced techniques, and its performance has therefore rapidly spread worldwide. However, the rate of biliary injuries has not decreased. The concept of the critical view of safety(CVS) was first documented two decades ago. Unexpected injuries are principally due to misidentification of human factors. The surgeon's assumption is a major cause of misidentification, and a high level of experience alone is not sufficient for successful LC. We herein describe tips and pitfalls of LC in detail and discuss various technical ***, based on a review of important papers and our own experience, we summarize the following mandatory protocol for safe LC:(1) consideration that a high level of experience alone is not enough;(2) recognition of the plateau involving the common hepatic duct and hepatic hilum;(3) blunt dissection until CVS exposure;(4) Calot's triangle clearance in the overhead view;(5) Calot's triangle clearance in the view from underneath;(6) dissection of the posterior right side of Calot's triangle;(7) removal of the gallbladder body; and(8) positive CVS exposure. We believe that adherence to this protocol will ensure successful and beneficial LC worldwide, even in patients with inflammatory changes and rare anatomies.
