There is no golden standard for the diagnosis of acute pancreatitis (AP). The diagnosis is currently based on clinical presentation, measurement of released pancreatic enzymes and imaging studies. Serum/urinary amylase, lipase and trypsinogen-2 dipstick are the most applicable methods in the clinical practice largely because of their simple, rapid, inexpensive and readily available assay methods. In addition to the clinical picture, inflammatory markers (CRP) or contrast enhanced CT can be used to assess the severity of acute pancreatitis. Multifactorial scoring systems (Ranson's prognostic signs, APACHE II, MOF-score) may be too cumbersome for clinical practice. Patient history, determination of AST, bilirubin and alkaline phosphatase levels as well as imaging studies such as ultrasonography and ERCP can be used to distinguish between biliary and non-biliary origin of the disease.

Zeolitic cages of the AST type are found in the novel scandium-squarate MOF, and the joining of them gives rise to a new binodal network with a unique topology; this new material is an efficient heterogeneous Lewis acid catalyst.

We investigated the effects of Moringa oleifera leaf powder (MOLP) as a dietary supplement on growth performance, gastrointestinal (GIT) morphometry and liver function using weanling Sprague Dawley rats to model humans under ad libitum and restricted feeding. An MOLP-based diet was generated by supplementing normal rat feed with the leaf powder at 20%. Four dietary regimens included normal rat feed fed at 20% of body mass (NRF: ad libitum), NRF fed at 14% of body mass (NRFR, restricted), Moringa-supplemented feeds fed at 20% and 14% of body mass (MOF: ad libitum and MOFR: restrictedly) respectively. Thirty-two pups were randomly assigned to the diets and fed for 5 weeks, after which they were fasted, euthanased and GIT viscera masses, lengths and histology were assessed. Blood was collected for metabolite and markers of liver function assays. Tibiae and femora lengths were used to determine linear growth. Rats fed the restricted diets had lower weekly body mass gains (p = 0.0001) than those on ad libitum feeding; however, they showed compensatory growth by 5 weeks. Terminally, the rats fed MOFR had shorter (p < 0.05) femora and tibiae than their counterparts on the other diets. Except on the caeca, diet had no effect on the absolute masses and lengths of GIT viscera. Relative to tibia length, rats on the MOF had significantly heavier stomachs and caeca and longer small and large intestines than their counterparts on NRF, but this was not supported histologically. Level of feeding and supplementation did not affect blood metabolite concentration, liver glycogen and lipid storage nor the plasma activities AST and ALP in the rats. Supplementing diets with MOLP under restricted access to feed (low calorific supply) might compromise linear growth.
