A 24-year-old woman was admitted to our hospital with acute paracetamol poisoning, and severe hepatic injury. The peak blood level of GOT, GPT and LDH were 32,600 U, 119,200 U and 36,500 U respectively. Glucagon-insulin and glutathione were administered to save the liver function. On the third hospital day, hemodialysis was administered to treat acute renal failure. On the 16th hospital day, when the liver and renal functions recovered, severe pulmonary congestion occurred and right heart catheterization revealed high pulmonary pressure. Echocardiography showed left ventricular enlargement accompanied by a severe diffuse impairment of left ventricular wall motion. Multi-focal ventricular arrhythmia was frequent during this period. Hemodialysis and artificial respiration were carried out for the treatment of heart failure. Three months after admission, myocardial perfusion scintigram showed patchy reduction in the uptake of Tl-201 throughout the myocardium, and left ventriculography showed mild diffuse impairment of the LV wall motion (ejection fraction: 49%). In this case, acute heart failure appeared approximately 2 weeks after the severe hepatic injury. Apparently myocardial damage following paracetamol overdosage is caused not only by direct toxicity but by severe metabolic derangement.

A deceased 59-year-old woman with insulin dependent diabetes mellitus complicated by chronic thyroiditis and chronic hepatitis was autopsied. She had had diabetes mellitus since she was 30 years old, and insulin therapy was started at 34 years. Laboratory findings were as follows: s-GOT 85, s-GPT 31, gamma-globulin 2.45 g/dl. Immunological tests were positive for anti-smooth muscle antibody and anti-ENA antibody with high titers of antithyroglobulin and anti-microsome antibodies. HLA analysis revealed the presence of DR-4. The thyroid biopsy specimen showed microscopic features characteristic of chronic thyroiditis at 52 years of age. She had been repeatedly admitted for the control of diabetes mellitus. She was admitted for the 9th time in June, 1987 following complaints of abdominal pain. After admission, her general condition became gradually worse, and she died of peritonitis in September, 1987. Pathological examination of the liver revealed an expansion of fibrous tissue on Glisson's capsule accompanied by lymphocytic infiltration and was diagnosed to be chronic inactive hepatitis. As for the thyroid gland, fibrous tissue replaced an extensive area of the thyroid gland, and normal thyroid tissue was not observed. Lymphocytic infiltration was less in comparison with that in the previous biopsy. As for the pancreas, atrophy of exocrine pancreatic tissue and fibrous change in interstitial tissue was observed. Lymphocytic infiltration was also seen in the interstitial exocrine tissue but not in the islet. Immunohistochemical examination of the islets using anti-insulin, glucagon and somatostatin antibodies by ABC peroxidase method showed the selective disappearance of B cells in the islets. The pathological changes in the thyroid gland, liver and pancreas suggest that autoimmune mechanism may be involved in the pathogenesis of chronic thyroiditis, chronic hepatitis and IDDM with exocrine pancreatic impairment in this case.

The viability of the graft after liver transplantation is considered to be expressed as the sum of the hepatocellular activity by re-flowing of the hepatic blood flow after transplantation and the hepatocellular injury derived from the cold ischemia of the liver which is indispensable for transplantation. In order to elucidate the hepatocellular injury in ischemic liver graft cold ischemic liver model without hepatectomy was prepared and liver functions, serum insulin, glucagon and cyclic AMP after glucagon loading were measured. The following results were obtained. 1) Influence of anoxia due to ischemia of the liver expressed by s-GOT, disappeared 2 days after operation but it lasted for long time by s-GPT. Re-elevation of s-GOT, s-GPT observed after 2 days or more was considered to be derived from the hepatocellular necrosis due to rejection. Incidentally, Al-phosphatase was useful for judging the rejection, but s-total bilirubin, s-total cholesterol and albumin were considered to be not useful as parameters for evaluating the viability of the graft. 2) The rejection and the hepatocellular necrosis had not influence on serum insulin, but serum glucagon corresponded to the hepatocellular necrosis and was useful index for the judgment of the hepatocellular damage in the graft. 3) The level of c-AMP after glucagon loading and the c-AMP response corresponded very well to the hepatocellular activity of the graft, and they were considered to be useful indices for evaluating the viability of the graft.

The pattern of organ toxicity after single injections of the antitumor agent titanocene dichloride (TDC) in ED90 (40 mg/kg) and LD10 (60 mg/kg) doses to female mice was investigated by analyzing various blood chemical parameters and the composition of urine at intervals between 30 min and 16 days after administration. Whereas the serum levels of electrolytes, blood urea nitrogen, creatinine, total bilirubin and cholesterol did not alter, marked and simultaneous increases in serum concentrations of the enzymes GLDH, GOT and GPT occurred pointing to cellular damage within liver parenchyma; these lesions were apparently reversible within 8 and 16 days after application of TDC even at the LD10 dose. Moreover, glucose concentration decreased immediately after TDC administration, obviously stimulating a regulative output of glucagon and cortisol; these effects were also reversible within 4 to 8 days after TDC administration. No hints to nephrotoxicity induced by TDC became manifest in the present study.

The aim of this paper is to elucidate the cause of death after 90 min of normothermic partial (2/3) ischemia of the liver and to examine the effects of glucagon, somatostatin, insulin, prednisolone and oral administration of polymyxin B (PB). The animals 24 hr after partial ischemia for 90 min were divided into two groups; namely, animals with normal appearance and those with moribund state. There were no significant differences in the plasma level of S-GOT, S-GPT, amino acids, NH3 or insulin, or in morphometrically estimated volume ratio of necrotic hepatocytes between the two groups of rats. The blood glucose level, however, was significantly decreased (31 +/- 28 mg/100 ml, n = 6) in the moribund rats with a higher incidence of positive Limulus gelation tests as compared with the rats with normal appearance (149 +/- 19, n = 5). The 1-day and 1-week survival rates of the animals were 42/62 (69%) and 32/61 (53%), respectively. A glucagon injection (1.5 mg/kg, after ischemia) was effective to elevate the 1-day survival rate (14/14), but failed to increase the 1-week survival rate (11/14). On the other hand, a somatostatin injection (100 micrograms/kg, after ischemia) or PB treatment (15 mg/kg/day x 5-9, before ischemia) succeeded to increase the 1-week survival rate (20/22 p less than 0.01 and 17/17 p less than 0.01, respectively), although no significant amelioration in transaminase levels or volume ratio of necrosis was demonstrated. It could be seen that a moribund state after partial ischemia was accompanied by severe hypoglycemic shock, and that the injection of somatostatin after ischemia or the annihilation of gram-negative bacteria by means of oral administration of polymyxin B before ischemia prevented the occurrence of the hypoglycemic shock.

The effect of intestinal bacterial flora and endotoxin on fatty liver with germfree (GF) and conventional (CV) rat in the 12th and 24th week was investigated after giving fatty diet which was added 1% cholesterol-0.5% cholic acid to the basic diet. Results are as follows. Serum biochemistry Serum GOT, GPT, ALP and cholesterol values increased after giving the fatty diet in both groups. Limulus Gelation Test In CV group, endotoxin was detected in 2 of 10 cases in portal blood and was completely absent in arterial blood. After the fatty diet, endotoxin increased gradually both in portal and arterial blood. Cyclic AMP values on glucagon challenge (P/B ratio) In both groups, the levels of the P/B ratio maintained low values compared with control. In CV group, the values were lower in endotoxin positive cases than negative ones. Hepatic carbohydrate metabolism Abnormal hepatic F6P , glucose, FDP and PEP values were observed in CV group and reduction of the levels of hepatic F6P , G6P and glucose values were remarkable in GF group. Hepatic G6P in CV group and FDP in GF group remained unchanged. Impairment of F6P and G6P in CV group, was significant in endotoxin positive cases than in negative ones.

Natural supplements comprise good efficacy with less adverse effects as against diabetic therapy, but their advancement as anti-diabetic agents is unsatisfactory with regard to the delivery system. Dipeptidyl peptidase-4 (DPP4)/CD26) can degrade glucagon-like pepetide-1 (GLP-1) which renders a decrease of blood glucose levels. 16-hydroxycleroda-3,13-dine-16,15-olide (HCD) extracted from Polyalthia longifolia, exhibits numerous medicinal potentials including hypoglycemic potential. On consideration of HCD application, the bioavailability is affected by low solubility. Extended experiments of anti-diabetic efficacy confirmed HCD biocompatible with mesoporous silica nanoparticles (MSNs) encapsulation resulted in a sustained release property in delivering HCD for the inhibition of DPP4 via the activity and protein levels of DPP4 analysis. In the enzymatic activity assay, MSN-HCD directly changed DPP4 activity. Moreover, MSN-HCD nanoparticles were treated with Caco-2 cells and the protein levels of DPP4 determined within the cells. The results revealed that MSN-HCD caused reduction of DPP4 activity in a time- and dose-dependent fashion. Orally administered MSN-HCD in diet-induced diabetic mice alleviated blood glucose via an oral glucose tolerance test. In addition, administration of MSN-HCD for five weeks revealed that the biochemical cues such as pyruvate transaminase (GPT), glutamate oxaloacetate transaminase (GOT), triglycerides (TG), cholesterol (CHO), and glycated hemoglobin (HbA1c) in mice were commendable as further confirmation of MSN-HCD efficacy and less adverse effects in down-regulation of hyperglycemia. Furthermore, this formulation effectively controlled blood glucose and significantly decreased the body weight of mice, suggesting that MSN-HCD exerts natural DPP4 inhibitor as a potential clinical drug for the treatment of diabetes.
