[Interventions for pancreatitis].

Approximately 20% of patients with acute pancreatitis develop complications that require surgical or radiological intervention. Radiology plays a central role, not only for imaging (course of the disease, detection of superinfection and their related complications, and development of necrosis) but also for the treatment of vascular and nonvascular complications. In the treatment of severe or necrotizing pancreatitis, a multidisciplinary staged approach with minimally invasive therapies such as endoscopic or percutaneous drainage should be used.

Role of linoleic acid in arsenical palmar keratosis.

Background: Chronic arsenic exposure can lead to palmoplantar keratosis. In the stratum corneum of skin, linoleic acid is of the utmost importance to the inflammation, keratinization, and regeneration processes.

Objectives: The aims of this study were: (i) to present quantitative information on the linoleic acid fraction of intercorneocyte lipids, and (ii) to elucidate the role of linoleic acid in the pathophysiology of arsenical keratosis.

Secretion of arsenic, cholesterol, vitamin E, and zinc from the site of arsenical melanosis and leucomelanosis in skin.

Background: Melanosis and leucomelanosis with or without keratosis are the earliest symptoms of arsenicosis. Uneven distribution of arsenical melanosis and leucomelanosis in skin led us to investigate the possibility of preferential secretion of arsenic and three constituents of sweat; cholesterol, vitamin E, and zinc.

Methods: Twenty-four-hour skin secretion was collected from skin lesions and unaffected sites of 20 patients.

Inhibitory effect of arsenic on aerobic gut flora in rat.

An in vivo study was carried on rats to see the influence of arsenic on aerobic gut flora. A significant inhibition of gut flora was observed after 2 weeks of administration of arsenic (1 mg/L) ad libitum with a decrease in stool arsenic level and increase in liver arsenic level. However, this inhibitory effect of arsenic on gut flora was not observed in presence of vitamin E (1 mg/day) or selenium (0.

Effect of additives on fiber yield improvement for kraft pulping of kadam (Anthocephalus chinensis).

Projected decline in future wood resources has prompted researchers to try various additives in existing pulping processes for fiber yield improvement. Many studies have been conducted in the past aimed at improving kraft pulp yield with the use of additives in the cooking liquor. In this study, the effects of anthraquinone (AQ) and 2-methylanthraquinone (MAQ) on the pulp yield of kadam (Anthocephalus chinensis) were investigated.
