The Mongolian gerbil (Meriones unguiculatus) is susceptible to infection with Giardia duodenalis trophozoites. Each animal was orally infected with 0.5 ml Diamond's TYIS-33 culture medium containing 10(6) trophozoites. Cysts were then collected and concentrated by sucrose gradient centrifugation. G. duodenalis cysts were first observed in feces on day 5 post-infection. The characteristic of G. ...

SEVERAL studies have compared the effects of sucrose and other carbohydrates on caries activity in rats receiving modifications of cariogenic diet 2000 of KEY= and JORDAN (1964) and it has been concluded that complete or intermittent replacement of dietary sucrose with other carbohydrates results in greater inhibition of caries on the molar smooth surfaces of rats than in the deep molar fissure...

Female rats 4 weeks old were fed diets including beef tallow or safflower oil in combination with sucrose or rice starch. At 8 weeks of age, half the rats were orally administered 2 of estrogen (mestranol) in5 Ml of safflower oil and half were fed the vehicle only. After 10 to 14 days of estrogen treatment, rats were fasted and exsanguinated. Alterations were found in weight gain, liver weights...

High-sucrose diet and metabolic acidosis have some similar effects on bone and they both reduce the formation of dentine. This series of experiments was conducted in order to get information about the effects of acidosis and alkalosis on dentine during primary dentinogenesis and also to ascertain if high-sucrose diet affects dentine formation via acidosis. Chronic metabolic acidosis (0.25 mol/L...

A water-soluble extract of Touchi, a traditional Chinese food, was found to exert a strong inhibitory activity against rat intestinal a-glucosidase. We orally administered sucrose (2 g/kg) with or without Touchi extract (TE) to normal rats at 100 and 500 mg/kg. Postprandial increases in blood glucose levels at 30 and 60 min after the administration of TE were significantly depressed compared wi...

Methadone and buprenorphine are commonly used as oral substitutes in opiate maintenance programs to treat persons who are dependent on heroin. During these programs, patients are not allowed to continue using illicit drugs. Abstinence can easily be monitored by urine tests with immunochemical methods. It is well known that the intravenous abuse of heroin substitutes like methadone or buprenorph...

In order to develop a kind of APAP double-release pellet capsules, which was prepared with the manual filling method, immediate and sustained release pellets certain proportion were by fluidized bed coating extrusion spheroidization process, respectively. It founded that both immediate-release sustained-release had smooth round surfaces. The particle size distribution ranged evenly from 16 35 m...

Effects of exogenously applied methyl jasmonate (MeJA) and sucrose on vase life and non-structural carbohydrate concentration in petals and leaves of cut ‘First Red’ roses were investigated. Roses were placed in sealed plastic containers and received MeJA vapour treatment (0.1 μL MeJA L-1) for 24 h at 20°C. Flowers were then placed in individual bottles containing 0 or 2% (v/v) sucrose solution...
