Pancreas survival

Those with type 1 diabetes mellitus produce insulin in insufficient amounts and tiierefore must have insulin supplementation to survive Type 1 diabetes usually has a rapid onset, occurs before die age of 20 years, produces more severe symptoms tiian type 2 diabetes, and is more difficult to control. Major symptoms of type 1 diabetes include hyperglycemia, polydipsia (increased thirst), polyphagia (increased appetite), polyuria (increased urination), and weight loss. Treatment of type 1 diabetes is particularly difficult to control because of the lack of insulin production by die pancreas. Treatment requires a strict regimen tiiat typically includes a carefully calculated diet, planned physical activity, home glucose testing several times a day, and multiple daily insulin injections. 

Diarrhea was observed in rats exposed for 5 days, 6 hours/day to both lethal and sublethal doses of P-endosulfan ( 250 mg/kg/day for males and i6 mg/kg/day for females) (Hoechst 1989b). Autopsy of animals from this study revealed that the mesenteric blood vessels of one of the surviving females exposed to 16 mg/kg/day were distended with blood, and that the small intestines of animals dying as a result of exposure were filled with a reddish fluid (500 mg/kg/day for males and 31.25 for mg/kg/day females). In contrast, no treatment-related effects were revealed by routine gross and histopathological examination of gastrointestinal tissues (stomach, small and large intestines, and pancreas) from rats exposed to doses of 27 mg/kg/day (females) and 81 mg/kg/day (males) for 30 days, 6 hours/day,... 

Most kidney transplant procedures are heterotopic, where the kidney is implanted above the pelvic bone and attached to the patient s iliac artery and vein. The ureter of the transplant kidney is attached directly to the recipient s bladder or native ureter. The native kidneys usually are not removed, and data have shown that under most circumstances, removal of the native kidneys does not influence patient survival and allograft survival. Special circumstances, however, such as renal cell carcinoma and PCKD, may necessitate native kidney removal.1,3 There were 16,477 (9914 deceased donors, 6563 living donors) kidney transplants and 903 simultaneous kidney-pancreas procedures done in 2005.3... 

All dead at 16,000 mg/kg diet. The 8000 mg/kg group had 80% mortality survivors had significantly reduced growth and feed conversion. At 4000 mg/kg, no significant effect on growth or survival zinc concentrations elevated in kidney, liver, intestinal mucosa, and pancreas— but values normal after 10 days on basal diet (Oh et al. 1979). 

No observed effects at 682 mg/kg diet (and lower), equivalent to 104-109 mg Zn/kg BW daily. At 6820 mg Zn/kg ration, however, adverse effects were documented on survival, growth, food and water intake, and blood chemistry lesions noted in pancreas, stomach, intestine, spleen, and kidney. 

In both types of diabetes, however, this normal process malfunctions. A gland called the pancreas, found just behind the stomach, makes insulin. In people with insulin-dependent diabetes, the pancreas does not produce insulin at all. This condition usually begins in childhood and is known as Type I (formerly called juvenile-onset) diabetes. These patients must have daily insulin injections to survive. People with non-insulin-dependent diabetes usually produce some insulin in their pancreas, but their bodies tissues do not respond well to the insulin signal and, therefore, do not metabolize the glucose properly, a condition known as insulin resistance.

Cyclosporine has been approved for use in allogeneic kidney, liver, and heart transplant patients and is under study for use in pancreas, bone marrow, single lung, and heart-lung transplant procedures. It is recommended that corticosteroids, such as prednisone, be used concomitantly, although at half or less of their usual dose. Such combined therapy leads to fewer side effects, a decreased incidence of infectious complications, efficacy of lower doses of cyclosporine, and a better history of patient survival. 

The oral LDso of isophorone was reported as 3450 mg/kg in male rats (Hazleton Labs 1964) and 2104-2150 mg/kg in female rats (Smyth et al. 1969, 1970). LDso values of 2700 200 mg/kg for male rats, 2100 200 mg/kg for female rats, and 2200 200 mg/kg for male mice also were reported by Dutertre-Catella (1976). The value reported by Hazleton Labs (1964) was estimated because the mortality data did not lend itself to statistical analysis. Furthermore, the doses were widely spaced, and the animals were fasted for only 3-4 hours before dosing, which could have interfered with gastrointestinal absorption of isophorone. Necropsy of rats that died revealed congestion of the lungs, kidneys, adrenals, and pancreas, and gastrointestinal inflammation. Necropsy of rats that survived the 14-day observation period revealed no effects. The studies by Smyth et al. (1969, 1970) were determinations of the joint toxic action of 27 pairs of industrial solvents (see Section 2.7 on Interactions with other chemicals), but the details of the individual LDs° determinations and the cause of death were not provided. Nevertheless, the values for isophorone were reproducible in the two studies by Smyth et al. (1969, 1970). The reason for the sex difference...

What is to be emphasized here is the fact that the per cent dose incorporation into the y- plus 0-globulin fractions of the plasma proteins of the hepatectomized rat is not measurably different from that noted in the eviscerated surviving rat. In other words, the concomitant presence of the gastrointestinal tract, pancreas, spleen, and mesentery structures has not grossly altered the qualitative or quantitative pat-... 

In further studies rats were treated with doses of THC up to 50 mg/kg and mice with up to 500 mg/kg 5 times a week for 2 years in a standard carcinogenicity test (11). After 2 years, more treated animals had survived than controls, probably because the treated animals ate less and had lower body weights. The treated animals also had a significantly lower incidence of the various cancers normally seen in aged rodents in testes, pancreas,... 

Characterised by sideroblastic anaemia and exocrine pancreas dysfunction. Usually fatal in infancy. The few patients who survive into adulthood often develop symptoms of Kearns-Sayre syndrome. It is very rare less than 100 cases have been reported. 

Proteolysis also provides carbon skeletons for gluconeogenesis. During starvation, degraded proteins are not replenished and serve as carbon sources for glucose synthesis. Initial sources of protein are those that turn over rapidly, such as proteins of the intestinal epithelium and the secretions of the pancreas. Proteolysis of muscle protein provides some of three-carbon precursors of glucose. However, survival for most animals depends on being able to move rapidly, which requires a large muscle mass, and so muscle loss must be minimized.
