We report a case of a 32-year-old woman with episodic right lower quadrant abdominal pain. With the diagnosis of either acute appendicitis or tubo-ovarian abscess, she was treated with antibiotics, which successfully relieved the pain and the inflammatory findings. She repeated the clinical condition a few times and antibiotics worked each time. In a year, her subjective symptoms became milder, however, a giant pelvic cyst appeared. She had an exploratory laparotomy to confirm this diagnosis. Histopathological studies revealed herniated appendiceal mucosa through the muscular layer associated with chronic inflammation and marked fibrosis. Gynecological disorders such as endometriosis or lutein cyst rupture was denied. These findings represent appendiceal diverticulitis. We discuss the clinical features of the disease and its relation with the pelvic pseudocyst.

The influences of DC and AC electric fields,at frequencies up to 1.48 MHz and the maximum strength of about 6 kV/cm,on soot formation and flame structure were investigated using a counterflow type acetylene diffusion *** distributions of flame luminosity,soot volume fraction,flame temperature and OH concentration in flame were measured by non-invasive detection methods. Under the influence of electric fields,the changes in distribution of the soot volume fraction were confirmed. Electric fields of high frequency and high intensity reduced the soot volume fraction,whereas other electric fields increased *** maximum values of flame temperature and OH concentration decreased. In the relationship between the maximum value of the soot volume fraction and the maximum temperature,the maximum soot volume fraction showed both increase and decrease with maximum temperatures depending on the frequencies and intensities of the electric fields,and both of them occurred at temperatures lower than 1900 *** production of the incipient particles seemed to be the dominant process controlling the soot volume fraction due to the electric *** luminosity of a sooting diffusion flame was found to depend on the volume fraction and temperature of the soot particles in the *** for the behavior of the flame in the electric fields,the ionic wind effect was not found to be dominant in the present work,and the result of the previous simulation based on the ionic wind theory was not consistent with the present experimental results.

We conducted molecular phylogenetic analyses of Japanese Rhacophorus species, especially of R. schlegelii and R. arboreus from the mainland, based on samples encompassing their known distribution ranges, and discussed about evolutionary history of Rhacophorus species within Japan. The common ancestor of Japanese Rhacophorus, except for R. owstoni from southern Ryukyus, was estimated to have diverged from a lineage occurring mainly in China about 7 MYBP. Both R. schlegelii and R. arboreus are genetically largely divergent between regions of eastern and western Japan, and this seems to have been promoted mainly by retreat to refugia. Retreats of the two species to different refugia sometimes in the past seem to have led restricted distribution of R. schlegelii in eastern and R. arboreus in western Japan, and brought their intraspecific variation patterns in morphology and breeding habit.

The Shangcheng stout salamander(Pachyhynobius shangchengensis) is a poorly known stream dwelling hynobiid salamander from China. We studied the reproduction, development and growth response of the salamander to different diets in captivity. Two females each produced two unique, striated egg sacs, with each containing 18 and 20, and 22 and 32 white eggs with an average diameter of 3.3 mm. Hatchlings(n = 27) had front- and hind-limb buds with interdigit membranes and a large yolk sac, and developed cornified finger and toe tips during further development. Metamorphosis occurred between d 441 and d 454 after hatching at an average total length of 94.8 mm(n = 21). These reproductive and developmental traits fit in well with the ancestral state reconstruction in hynobiids. If corrected for dry mass, feed conversion ratios obtained by feeding bloodworms(Chironomidae) to P. shangchengensis larvae and mealworms(Tenebrio molitor) to postmetamorphs, were very low(0.33 and 0.34 respectively), equaling a very high mass conversion efficiency.

There are some reports that coffee consumption improves insulin resistance. Therefore, we investigated the link between metabolic syndrome and coffee, tea and green tea consumption in Japanese. We used data of 150 men and 227 women who were not taking any medications, aged 22 - 74 years, in this cross-sectional investigation study. Habitual coffee, tea and green tea consumption was defined as drinking one or more cups of coffee, tea and green tea per day. The diagnosis of metabolic syndrome was based on the Japanese criteria. In subjects without medications, 34 men (22.7%) and 10 women (4.4%) were diagnosed with metabolic syndrome. Coffee and green tea consumption was weakly and positively correlated with age in women. Significant differences of coffee consumption between women with and without abdominal obesity, dyslipidemia and hypertension, tea consumption between men with and without dyslipidemia were noted after adjusting for age. However, there were no significant differences of other consumption between subjects with and without metabolic syndrome in both sexes. Among Japanese not taking medications, coffee, tea and green tea consumption was not clearly associated with metabolic syndrome in the Japanese population.
