Silage is a major component of cattle rations, so the improvement of silage quality by the inoculation of lactic acid bacteria is of great interest. In this study, commercially distributed Lactobacillus plantram and Lactobacillus rhamnousas NGRI 0110 were used for ensilaging of guinea grass. The four treatments used were a control silage, a silage with cellulase addition, a silage with cellulose+L. plantram addition, and a silage with cellulose + NGRI 0110 addition. Silage quality, voluntary intake, nutrient digestibility, and the characteristics of ruminal fluid of wethers were investigated. Silage to which lactic acid bacteria were added showed low pH and acetic acid concentration and the highest lactic acid content. Dry matter and organic matter digestibility were significantly (p<0.05) increased by cellulase addition and significantly (p<0.05) higher values were observed in L. plantram- and NGRI 0110-added silage. Voluntary intake of NGRI 0110-added silage was the highest and that of control silage was the lowest. We concluded that the observed ability of NGRI 0110 to tolerate low pH and to continue lactic acid fermentation in high lactic acid concentration had also occurred in actual ensilaging. The results indicate that the addition of lactic acid bacteria might improve silage quality and increase digestibility and voluntary intake. The potential for improvement by NGRI 0110 was higher than that to be gained by the use of commercially available lactic acid bacteria.

An optical-fiber-array spatial filtering velocimeter (SFV) was developed and applied to the flow velocity measurement in the microscopic region. A frequency shifter was assembled in the signal processing unit of the velocimeter, and it enabled detection of the direction of flow which often changed reversely. The structure of the SFV was very simple and was available to be installed in a microscope. Output signals of the SFV were detected by photodetectors and processed by means of FFT to obtain the spectral frequency related to the flow velocity. The whole system was tested both in vitro and in-vivo, and especially used to measure the velocity changes of lymph flow and blood flow in the microcirculatory system of the rats. The results showed that the developed SFV was conspicuously useful for the velocity measurement even in the microscopic region.

A 62-year-old man underwent endoscopic mucosal resection for early gastric cancer. The follow-up computed tomography revealed biliary dilatation. The tumor was located in the lower bile duct with biliary dilatation, and no evidence of metastasis in other organs was noted. The patient underwent subtotal stomach-preserving pancreatoduodenectomy with pancreaticogastrostomy and Billroth I anastomosis. At 13 months after the operation, gastrointestinal endoscopy revealed a tumor lesion in the pancreaticogastrostomy site. Computed tomography revealed that the lesion was low enhanced in the pancreaticogastrostomy site and there was no evidence of other distant metastasis. Partial pancreatectomy was performed. Pathological findings of the tumor in the stump of the pancreas revealed findings similar to that of primary biliary carcinoma. Apparently, the patient was diagnosed with recurrence of bile duct cancer via the pancreatic duct. The patient underwent adjuvant chemotherapy for one year subsequent to partial pancreatectomy as the second operation. For 40 months after the second operation, there has been no evidence of recurrence of cancer.

Purpose: This study aimed to examine the effects of 4 main types of gastrectomy for proximal gastric cancer on postoperative symptoms, living status, and quality of life (QOL) using the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45). Materials and Methods: We surveyed 1,685 patients with upper one-third gastric cancer who underwent total gastrectomy (TG; n=1,020), proximal gastrectomy (PG; n=518), TG with jejunal pouch reconstruction (TGJP; n=93), or small remnant distal gastrectomy (SRDG; n=54). The 19 main outcome measures (MOMs) of the PGSAS-45 were compared using the analysis of means (ANOM), and the general QOL score was calculated for each gastrectomy type. Results: Patients who underwent TG experienced the lowest postoperative QOL. ANOM showed that 10 MOMs were worse in patients with TG. Four MOMs improved in patients with PG, while 1 worsened. One MOM was improved in patients with TGJP versus 8 MOMs in patients with SRDG. The general QOL scores were as follows: SRDG (+39 points), TGJP (+6 points), PG (+3 points), and TG (−1 point). Conclusions: The TG group experienced the greatest decline in postoperative QOL. SRDG and PG, which preserve part of the stomach without compromising curability, and TGJP, which is used when TG is required, enhance the postoperative QOL of patients with proximal gastric cancer. When selecting the optimal gastrectomy method, it is essential to understand the characteristics of each and actively incorporate guidance to improve postoperative QOL.

Purpose Most studies have investigated the differences in postgastrectomy quality of life (QOL) based on the surgical procedure or reconstruction method adopted; only a few studies have compared QOL based on tumor location. This large-scale study aims to investigate the differences in QOL between patients with esophagogastric junction cancer (EGJC) and those with upper third gastric cancer (UGC) undergoing the same gastrectomy procedure to evaluate the impact of tumor location on postoperative QOL. Methods The Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaire was distributed in 70 institutions to 2,364 patients who underwent gastrectomy for EGJC or UGC. A total of 1,909 patients were eligible for the study, and 1,744 patients who underwent total gastrectomy (TG) or proximal gastrectomy (PG) were selected for the final analysis. These patients were divided into EGJC and UGC groups; thereafter, the PGSAS-45 main outcome measures (MOMs) were compared between the two groups for each type of gastrectomy. Results Among the post-TG patients, only one MOM was significantly better in the UGC group than in the EGJC group. Conversely, among the post-PG patients, postoperative QOL was significantly better in 6 out of 19 MOMs in the UGC group than in the EGJC group. Conclusions Tumor location had a minimal effect on the postoperative QOL of post-TG patients, whereas among post-PG patients, there were definite differences in postoperative QOL between the two groups. It seems reasonable to conservatively estimate the benefits of PG in patients with EGJC compared to those in patients with UGC.
