  • Many studies have identified the phosphatidylinositol 3-kinase (PI3K) as a key regulator for various cellular functions including cell survival, growth and motility. We have previously shown that H-ras, but not N-ras. induces invasiveness and motility in human breast epithelial cells (MCF10A), while both H-ras and N-ras induce transformed phenotype. In the present study, we wished to investigate the functional role of PI3K pathway in H-ra-induced invasive phenotype and motility of MCF10A cells. (omitted)

  • In order to find out the effects of GABA on the rabbit's intestinal motility, the following experiments were carried out using Magnus method and the results obtained were as follows: 1. GABA inhibited the intestinal motility of rabbits initially. 2. GABA potentiated the inhibitory action of adrenaline and nor-adrenaline. 3. GABA inhibited the accelerating activity of acetylcholine on the intestinal motility by its anti acetylcholine effect. 4. The inhibitory action of GABA was unaffected with atropinization, strychnin, picrotoxin treatment, but the accelerating activity of GABA observed in some cases was only in the picrotoxin treatment.

  • Esophageal motility was evaluated from the analysis of 10 consecutive swallows using liquid bolus containing 0.5 mCi of $^{99m}Tc$ tin colloid. We have reviewed our experience of esophageal transit study in the 20 normal volunteers and 55 patients with dysphagia that was not related to mechanical obstruction. The purpose of this study is to measure the esophageal transit in normal subjects and in patients with various esophageal motility disorders. The overall sensitivity and specificity of radionuclide esophageal transit study in detecting esophageal motor abnormality were compared with manometric results as a gold standard, which were 80% and 100% respectively. Radionuclide transit study is a safe, rapid, noninvasive test and suitable as a screening test for esophageal motor disorders.

  • Thirty five couples were treated by intrauterine insemination with sperm prepared by a washing and swim-up method. Fifteen women conceived(42.9%). Sperm washing and swim-up was found to significantly improve sperm motility for men of infertile couples and the increment of percent sperm motility after sperm preparation allowed significant differentiation of pregnant and nonpregnant patients in asthenozoospermia(submotile) group (p<0.01). The author suggest that the increment of percent sperm motility after sperm washing and swim-up could be a useful screening tool for in vitro procedure proposed to improve fertility in the intrauterine insemination of asthenozoospermia.

  • The surgical indications for the treatment of gastroesophageal reflux disease (GERD) in patients with esophageal motility disorders have been debated. We report a case of antireflux surgery performed in a patient with absent esophageal motility as categorized by the Chicago classification (2011). A 54-year-old man underwent laparoscopic Toupet fundoplication due to apparent GERD and desire to discontinue all medications. After surgery, his subjective symptoms improved. Furthermore, objective findings including manometry and 24-hour pH-metry also improved. In our experience, antireflux surgery can improve GERD symptoms patients, even with absent esophageal motility.

  • Although the Insamyangwee-Tang has been widely used in clinical purposes in the oriental medicine and its clinical efficiency is documented for the cases of gastritis, gastric ulcer and enteritis but the experimental study on these has not been undertaken. So,To investigate the clinical efficiency, of Insamyangwee-Tang and validate its oriental medical theory, these experiments were undertaken, by being compared with animal experiment. ?The following results were obtained. ?1. By effect of Insamyangwee-Tang on isolated ileum from mice, rats, rabbits and Guinea pigs, the motility of ileums was inhibited remarkably. ?2. By effect of Insamyangwee-Tang on motility of the small intestine in rabbits, the motility was inhibited remarkably too. ?3. Insamyangwee-Tang inhibited charcoal transport functions in the small intestine of mice. ?4. By effect of Insamyangwee-Tang on isolated duodenum from rats, the motility of duodenum was inhibited remarkably.?5. Gastric juice and pepsin secretion was decreased, anti-ulceration effect was recognized.

  • Autotaxin (ATX) is a 125-kDa glycoprotein and a strong motogen that can increase invasiveness and angiogenesis, originally isolated from the conditioned medium of human melanoma A2058 cells. And it is a strong. Recently, we suggested that ATX promotes motility via G protein-coupled PI3K$\gamma$, and Cdc42/Racl are essential for ATX-induced tumor cell motility in A2058 melanoma cells. In the present study, we found that activation of p21-activated kinase1 (PAK1) was required for ATX-induced cell motility. (omitted)
