gastric ulcer is one of the most prevalent gastrointestinal (gi) disorders, which affects approximately 5-10% of people during their life. in recent years, plentiful works have been carried out on herbal medicine to clarify their potential efficacy in gastric ulcer prevention or management. tripleuro-spermum disciforme is one of the indigenous plants that is readily available and has been tradi...

EiVTURIA inaequalis (Cke.) Wint., the ascomycetous pathogen of apple scab, Yhas been shown to have adaptations similar to the eight-spored Neurospora species for use in genetic analyses (KEITT and LANGFORD 1941; SHAY and KEITT 1945; KEITT et al. 1948; BOONE and KEITT 1956). I t has, in addition, two very important advantages over Neurospora: 1) I t is pathogenic and can be studied in vivo; and ...

Agnitundirasa was tested for antigastric ulcer activity in shay rat model. Oral dose of 10 mg/kg reduced the ulceration in shay rat. With 20mg/kg dose the ulceration was completely absent. The antigastric ulcer activity of agnitundirasa (20 mg/kg) was found to be equal to the effect produced by cimetidine (20 mg/kg). The reduction in gastric acidity was more with cimetidine and the reduction in...

[1] The scaling of the reconnection rate and ion and electron outflow speeds with upstream magnetic field strengths and plasma mass densities during asymmetric collisionless (Hall) reconnection without a guide field is studied using two-dimensional two-fluid simulations. The results agree with a recent theory by Cassak and Shay (2007). It is found that the normalized reconnection rate is on the...

The gastric ulcerogenic effect of the glucocorticoid, prednisolone, was studied in albino rats. Shay operation in forestomachectomized rats with intact adrenals induced acute gastric ulcers in the corpus, whereas adrenalectomy prevented the development of gastric ulcers in another group of forestomachectomized Shay rats. Only superficial erosion of gastric epithelium was noticed in 66.67% of th...

T his special issue of Science is called " Piecing Together Human Aging " and its scientific content, as you will see in the following pages, is devoted mainly to the life and death cycles of the cells and tissues that compose our bodies. The topic ushers in some troubling thoughts about the way we wear out, as well as about the length of life and its quality— two features that are sometimes in...
