Insecticidal effects of Agnique MMF were investigated in the coastal brackish water shrimp farms in the Tan Thuan commune, Dam Doi district of Ca Mau province in 2000. The investigations were made in terracotta jars and shrimp ponds with the surface area 30m2 and 1000m2 each. Agnique MMF was found to have a high and fast killing effect on larvae of An.sundaicus at all three testing doses of 0.3ml/m2, 0.4ml/m2 and 0.5ml/m2. Especially larvae at instars of III, IV and pupae. However, the insecticide produced a low effect on Culex sitiens killing larvae of IV ins tar and only retarding larvae of I, II, III instar. The residual effect of Agnique MMF was found to be 14 days in the terracotta jars and 6 days in the ponds. In the direct observations, Agnique MMF was found to have no negative effects on rearing shrimps

Prospective study on 107 bleeding peptic ulcer patients treated at Hospital No 103 from July 2001 to December 2002. Participants were divided into 2 groups. Group 1 received hemostatic therapy with polidocanol solution (PLS). Group 2 were treated by hypertonic saline-epinephrine (HSE) solution. Results: The general rate of successful hemostasis was 96.3%, in PLS group was 92.3% and in HSE group was 100%. There were not differences in the rates of initial hemostasis between 2 groups (p>0.05). Hemostatic effect was achieved after the first injection in 76.9% (40 patients) of PLS group and in 85.5% (47 patients) of HSE group. Some patients needed 2nd injections (PLS group: 15.4%, HSE group: 3.7%). Both solutions were effective in the treatment of bleeding peptic ulcer. HSE solution is safe, simple, low cost, and appropriate in Vietnam.

Herein, we report a case of unusually elevated serum insulin level as a result of increased anti-insulin antibody (IA)-bound insulin after continuous subcutaneous insulin infusion therapy. Detecting free insulin (unbound IAs) levels after polyethylene glycol pre-treatment could be useful to assess functional insulin levels in diabetic patients receiving insulin therapy. The E170 insulin assay can estimate total insulin (bound IAs and free insulin) levels, but it does not measure the levels of exogenous insulin analogues.

Penconazole-resistant and cabendazim-resistant mutants of Venturiu inaequalis were developed by chemical (MNNG) mutagenesis. Protoplasts of these mutants were isolated and fused using polyethylene glycol as the fusogen. Fusants were classified into parental, non-parental and recombinant types. The recombinants were resistant to penconazole and carbendazim. The double resistant strains were stable and exhibited pathogenicity on fungicide-sprayed and unsprayed apple twigs.

OBJECTIVE: This study aims to assess the effects of the different thicknesses of body-shade resin layers on the color of polyetheretherketone (PEEK)-Crea.lign restorations. METHODS: Five PEEK specimens with the thickness of 0.6 mm were prepared. The color values of PEEK specimens were measured. Afterward, opaque-shade resin layers (0.1 mm) and body-shade resin layers (1.5 mm) were stacked with mold. The five specimens were evenly ground to a thickness of 1.4, 1.2, 1.0, 0.8, 0.6, 0.4, 0.2, and 0.0 mm in sequence. After grinding and ultrasonic cleaning, the color value was measured. RESULTS: With the constant thickness of PEEK and 0.1 mm thickness of opaque-shade resin layer, the L*, a*, and b* values all showed downward trend with the increased thickness of the body-shade resin layer (1.0-1.4 mm). With the constant thickness of PEEK and 0.1 mm thickness of opaque-shade resin layer, the color difference between the adjacent groups was less than 1.5 NBS. This difference between nonadjacent groups was more than 1.5 NBS when the thickness of the body-shade resin layer reached 0.6 mm. Color difference between PEEK-Crea.lign restoration and PEEK was more than 1.5 NBS. CONCLUSIONS The thickness change in the body-shade resin layers influence the color of the PEEK-Crea.lign restorations. Using A2 shade Crea.lign, opaque-shade resin layer thickness is 0.1 and 0.6 mm thickness of body-shade resin layer can produce color which clinically acceptable.

BACKGROUND/AIMS: In the present study, we evaluated the efficacy and tolerability between same-day bowel preparation protocols using 2 sachets of Picosulfate and a 4 L split-dose polyethylene glycol (PEG) bowel preparation for afternoon colonoscopy. METHODS: The study had a single-center, prospective, randomized, and investigator-blinded, non-inferiority design. We evaluated bowel preparation quality according to the Ottawa scale, patient tolerability, compliance, incidence of adverse events, sleep quality, and polyp/adenoma detection rate. RESULTS: Among the 196 patients analyzed (mean age, 55.3 years; 50.3% men), 97 received the same-day regimen of 2 sachets of picosulfate (group A) and 99 received the 4 L split-dose PEG regimen (group B). The Ottawa score of the total colon was 4.05+/-1.56 in group A and 3.80+/-1.55 in group B (P=0.255). The proportion of patients having adequate bowel preparation in the same-day picosulfate group (61.5%) was slightly less than the 4 L PEG group (71.3%); however, the difference was not statistically significant (P=0.133). Tolerability of the group A regimen was superior to that of the group B regimen (P<0.000). The same-day picosulfate regimen was associated with fewer adverse events, such as abdominal bloating (P=0.037) and better sleep quality (P<0.000). CONCLUSIONS: The same-day picosulfate regimen and the 4 L split-dose PEG regimen had similar efficacy in bowel preparation for afternoon colonoscopy. However, the same-day picosulfate regimen was easier to administer, produced fewer adverse events, and enabled better sleep quality.

PURPOSE: To determine optimal maintenance dose and to evaluation the efficacy and safety of polyethylene glycol 4000 (PEG4000) in children with chronic functional constipation. METHODS: This study enrolled 41 children with chronic functional constipation at the Konkuk university hospital August 2005, then June, 2007. Effective maintenance dose was designed as initial amount of PEG4000 that improved frequency, bowel movement, stool consistency for 2 months. Clinical outcome was analysed on the basis of defecation diary. Adverse effect was monitored clinically and biochemically. RESULTS: As a whole group effective maintenance dose of PEG4000 was 0.550.16 g/kg/day (0.25-0.86). With respect to age, 3-5 years (0.600.15), 6-8 years (0.570.16), 9-13 years (0.440.14) (P=0.024). With respect to body weight, <30 kg (0.620.14), 30 kg (0.410.10) (P=0.001). One child comlained apigastric soreness on medication. CONCLUSION: PEG4000 is effective and safe in children with chronic constipation. Initial maintenance dose of PEG4000 was 0.55 g/kg/day.
