Assessment of probiotic adhesion and inhibitory effect on Escherichia coli and Salmonella adhesion.

In this study, we screened bacterial strains to identify specific probiotics to treat pig diarrhea caused by Escherichia coli or Salmonella. The potential probiotics were assayed for their survival in gastrointestinal solution, their antimicrobial activity, cell-surface properties, adhesion to Caco-2 cells, and inhibition of pathogen adhesion. Nine out of the 20 strains tested showed high tolerance of a simulated gastrointestinal environment and six strains exerted antagonistic effects against enterohemorrhagic E.

Different Doses of Oxycodone for Endoscopic Injection Sclerotherapy of Esophageal Varices.

BACKGROUND The aim of the present study was to evaluate the effects of different doses of oxycodone during endoscopic injection sclerotherapy (EIS) for esophageal varices with painless sclerosing agents. MATERIAL AND METHODS A total of 119 patients were randomly divided into 3 groups: Group A, midazolam and 0.075 mg/kg oxycodone (n=40); Group B, midazolam and 0.

Acoustic Shadowing Facilitates Ultrasound-guided Radial Artery Cannulation in Young Children.

Background: Arterial cannulation in young children can be challenging. Ultrasound guidance using focused acoustic shadowing may be suitable for guiding radial artery puncture in young children. The present research tested the hypothesis that ultrasound guidance using focused acoustic shadowing helps increase the success rate of radial artery cannulation in this population.

Combined use of hyperbaric and hypobaric ropivacaine significantly improves hemodynamic characteristics in spinal anesthesia for caesarean section: a prospective, double-blind, randomized, controlled study.

Purpose: To observe the hemodynamic changes of parturients in the combined use of hyperbaric (4 mg) and hypobaric (6 mg) ropivacaine during spinal anesthesia for caesarean section in this randomized double-blind study.

Methods: Parturients (n = 136) undergoing elective cesarean delivery were randomly and equally allocated to receive either combined hyperbaric and hypobaric ropivacaine (Group A) or hyperbaric ropivacaine (Group B). Outcome measures were: hemodynamic characteristics, maximum height of sensory block, time to achieve T8 sensory blockade level, incidence of complications, Apgar scores at 1 and 5 min, and neonatal blood gas analysis.

Influence of lateral decubitus positioning after combined use of hyperbaric and hypobaric ropivacaine on hemodynamic characteristics in spinal anesthesia for caesarean section.

Purpose: Positioning of the patient during and after surgery can have significant implications on recovery. Therefore, the purpose of the present study was to determine the influence of placing patients in a lateral decubitus position for 15 min after combined use of hyperbaric and hypobaric ropivacaine and assess hemodynamic characteristics during spinal anesthesia for caesarean section.

Methods: One hundred-forty patients undergoing elective cesarean delivery with combined use of hyperbaric and hypobaric ropivacaine were included in the present study.

Effective analgesic dose of dexamethasone after painless abortion.

Background And Purpose: Dexamethasone is known to produce analgesic effects, but the optimal analgesic dosage of dexamethasone remains unclear, especially in patients without postoperative use of other analgesics. The purpose of this study was to explore the effective analgesic dose of dexamethasone in day surgery patients undergoing painless abortion.

Methods: 287 patients undergoing painless abortion were randomly assigned to one of four groups: control group receiving saline and dexamethasone groups receiving 0.

[Influence of transfection with human transforming growth factor-beta1 gene on the osteogenic potential of the cultured human gingival fibroblast].

Objective: To study the influence of transfection with human transforming growth factor-beta1 (hTGF-beta1) gene on the osteogenic potential and differentiation of the cultured human gingival fibroblast (GF).

Methods: Enzyme kinetics method was used to measure the effects of the transfection on the alkaline phosphatase (ALP) activity. Immunohistochemistry stain and image analysis were applied to evaluate the alteration of the content of osteopontin (OPN), bone sialoprotein (BSP), osteonectin (ON), osteocalcin (OC) in the GF with transfection.

[Effects of gingival fibroblasts transfected with human transform growth factor-beta1 gene on improving the periodontal tissue regeneration].

Objective: To evaluate the effects of gingival fibroblasts (GF) transfected with hTGF-beta1 gene on improving the periodontal tissue regeneration for the repair of degree II artificial furcation defects.

Methods: The gingival fibroblasts transfected with hTGF-beta1 gene was compounded to the cuttlebone-transformed nanometer hydroxyapatite (CBHA) material from the cuttlefish in vitro, the degree II furcation defects on the premolars of dogs were produced surgically, and the compound was to implanted into the defect (transfected group), and compared with the compound of periodontal ligament cells (PDLC) with nanometer HA material and the compound of untransfected GF with HA. The results were examined histologically 8 weeks after operation.
