The present case was a 44-year-old man who had been diagnosed as having noninsulin-dependent diabetes mellitus 2 years before admission. He gradually showed severe neuropathy and emaciation because of poor control of his blood glucose levels. He was admitted to our hospital because of disturbance of consciousness with hyponatremia. The endocrinological findings including thyroid and adrenal functions revealed no abnormalities. Insufficiency of water diuresis was noted in the water loading test. Severe orthostatic hypotension was noted during the standing up test, and an excessive response in the plasma ADH level was also noted. These findings demonstrated that excessive ADH secretion occurred to compensate for the fall in blood pressure because of the breakdown of homeostatic regulation in blood pressure due to diabetic neuropathy. It is suggested that hyponatremia seemed to be subsequently induced by hypersecretion of ADH.

Pathomorphologic studies were carried out on three cases of bovine diabetes mellitus with clinical signs of polydipsia, polyuria, severe emaciation, glycosuria, persistent hyperglycemia, and decreased glucose tolerance. At necropsy, two animals had atrophy of the pancreas, whereas other visceral organs, including the endocrine organs, showed no significant changes. Microscopically, there was atrophy and reduced numbers of pancreatic islets accompanied by interlobular and interacinar fibrosis and compensatory enlargement of some remaining islets. Lymphocytes were observed commonly around and within atrophic islets and occasionally around and within enlarged islets. Vacuolar degeneration with occasional accumulation of glycogen granules was observed in the beta-cells of these enlarged islets. Immunohistochemical studies of atrophic islets demonstrated complete loss of beta-cells or only a few small beta-cells. There also was a corresponding decrease in the number of cells that stained with anti-glucagon (alpha-cells) or anti-somatostatin (delta-cells) antibodies. The vacuolated cells in the enlarged islets stained strongly with anti-insulin antibody (beta-cells). Ultrastructurally, the majority of cells in the atrophic islets had reduced cytoplasmic volume and few secretory granules, features consistent with alpha-cells. In contrast, enlarged islets that had prominent immunohistochemical staining for insulin (beta-cells) consisted of beta-cells with cytosolic edema, mitochondrial swelling, dilated smooth endoplasmic reticulum, and reduced numbers of or degranulated secretory granules. These pathomorphologic features found in cattle are similar to those found in juvenile-onset insulin-dependent diabetes mellitus in human beings and suggest autoimmune involvement in diabetes.

A 68-year-old man who worked as an editor was admitted to Aichi Medical University Hospital due to dyspnea on exertion and emaciation. The patient had noticed rapid weight loss during diet therapy for diabetes mellitus that started in the beginning of July, 1993. Laboratory examinations revealed elevated levels of LDH and amylase in serum. Ultrasonography disclosed minimal ascites. Dyspnea on exertion developed in September, 1993. Chest roentgenography showed diffuse bilateral small nodular or reticular opacities. CT-guided percutaneous needle aspiration was done and cytologic examination of a specimen of lung tissue revealed papillary adenocarcinoma. The diagnosis was bronchiolo-alveolar carcinoma. Serum levels of amylase were elevated. The amylase isozyme pattern was of the salivary type. Serum levels of CA19-9 and CEA were also elevated. The patient died of respiratory failure on December 4, 1993. Postmortem examination revealed diffuse small nodules in both lungs. Examination of the nodules showed bronchiolo-alveolar cell carcinoma. The tumor cells stained positively for amylase (salivary type, not pancreatic type) CA19-9, and CEA by the avidin biotin complex method, but they were immunohistologically negative for AFP. We conclude that this lung cancer produced amylase, CA19-9, and CEA. We know of only a few reports of cases in which lung cancer produced both amylase and CA19-9.

A 9-month-old bull was presented with a history of runting and glucosuria. The bull showed major signs of diabetes mellitus, such as polyuria, polydipsia, polyphagia, emaciation, glucosuria, and ketonuria, but persistent hyperglycemia was missing. Because in an intravenous glucose tolerance test glucose disappearance was only insignificantly more rapid in a non-diabetic age-matched control than in the diabetic bull a butyrate-stimulated insulin response test was performed. Insulin response to butyrate infusion was markedly impaired in the diabetic bull compared with the non-diabetic bull. At necropsy hepatic cirrhosis was noticed and suggestive signs for diabetes mellitus were seen in liver and kidneys.

Diabetes mellitus is uncommon in infancy and newborn period. The two common forms seen are the transient and permanent forms of diabetes mellitus of the newborn. They have to be differentiated from the transient hyperglycemic states (Blood sugar > 125 mg/dl) seen in newborns who receive parenteral glucose infusions and in those with septicemia and CNS disorders. Transient diabetes mellitus of the newborn (TDNB) is defined as hyperglycemia occurring within the first month of life lasting at least 2 weeks and requiring insulin therapy. Most of these cases resolve spontaneously by 4 months. It has a reported incidence of 1 in 45,000 to 60,000 live births. The most likely etiology is a maturational delay of cAMP mediated insulin release. The clinical features include small for datedness, proneness for birth asphyxia, open-eye alert facies, dehydration, emaciation, polyuria and poydipsia. These children are prone to septicemia and urinary tract infections. They have hyperglycemia, glucosuria, absent or mild ketonuria, low basal insulin, C-peptide and IGF-1 levels. Treatment consists of hydration and judicious administration of insulin with close monitoring. Thirty percent of these children are likely to develop permanent neonatal diabetes. Compared to transient form, permanent diabetes mellitus is uncommon. It is usually due to pancreatic dysgenesis often associated with other malformations and rarely due to type 1 diabetes mellitus. The diagnosis is based on the demonstration of both exocrine and endocrine pancreatic dysfunction. These children are managed as type 1 diabetes mellitus. They are prone to develop the vascular complications of diabetes at an earlier date.

Using a swine abdominal organ cluster transplantation model, we investigated the postoperative function and immunological reactions of a cluster graft and evaluated the immunosuppressive activity of FK506. The animals were divided into two groups. Group I (n = 6) served as controls, while in group II (n = 6) a daily dose of 0.1 mg/kg FK506 was given intramuscularly. Postoperative pancreatitis was the most important factor influencing the early outcome in both groups. In group I, the cause of late death was cachexia due to diabetes mellitus induced by pancreatic rejection. In group II, emaciation despite a well-functioning graft was the principal cause of late death. Histologically, in group I the grade of rejection in the pancreas was more severe than in the liver, and no sign of rejection was observed in group II. In conclusion, the pancreas suffered more severe rejection than the liver, and FK506 could significantly prevent cluster allograft rejection in this model.

Adequate energy intake including carbohydrates is essential to maintain bone mass. Emaciation along with deficiency in nutrients, such as calcium, vitamin D, and protein is a significant risk factor for bone loss, and should be avoided. However, there is no clinical evidence that shows the direct effects of carbohydrate on bone mass. On the other hand, excessive intake of carbohydrates results in obesity, which causes other metabolic diseases such as diabetes mellitus (DM). Therefore, dietary regimen must be balanced in general, and complications and conditions of individual patients should be taken well into account. In addition, energy intake is a basis for adequate exercise in order to maintain physical activity and ideal body weight, which will further decrease the risk of bone fracture. Some indigestible carbohydrates, such as inulin and oligofructose, are shown to increase the availability of minerals from foods, and thus can be beneficial to bone mass.

We report herein the case of a 28-year-old man presenting with hyperglycemic chorea-ballism (HCB) in addition to mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS). He was admitted to a local hospital due to weight loss, general fatigue and thirst. The patient had diabetes mellitus, with a blood glucose level of 738 mg/dl and HbA1c of 19.8%. Although insulin therapy improved hyperglycemia, he noticed involuntary movements in the right upper and lower limbs, which subsequently extended to the left side. The patient was thus transferred to our hospital. He displayed short stature (154 cm) and emaciation, and a maternal family history of diabetes mellitus was elicited. He had no history of stroke-like episode, headache, vomiting and seizure. Neurological examination revealed low intelligence (IQ 57), mild sensorineural deafness, and chorea-ballism in the extremities and head without ptosis or eye movement disturbance. Brain computed tomography (CT) demonstrated areas of high density, while T1-weighted magnetic resonance imaging (MRI) revealed extreme hyperintensity and T2-weighted MRI showed hyperintensity in bilateral caudate nuclei, putamina and globi pallidus. HCB was diagnosed. In, CSF, lactate level was increased to 43.9 mg/dl (n, 4-16), pyruvate level was 1.65 mg/dl (n, 0.3-0.9) and total protein concentration was 59 mg/dl. Histological examination of a biopsy sample from the biceps brachii muscle demonstrated ragged-red fibers. An A3243G point mutation in the tRNA(Leu(UUR)) gene was detected, indicating the presence of MELAS. Involuntary movements improved on treatment with haloperidol up to 4.5 mg/day. HCB usually appears in elderly individuals, and cases less than 40-years-old are very rare. The mitochondrial dysfunction in MELAS may accelerate development of HCB.

1. In work along this line it is most important to have a simple method of determining the catalytic activity of tissues. The method must be such that several observations can be made during a single experiment, so that a better idea can be obtained of the velocity of the reaction at various intervals. 2. The catalytic activity of human tissues varies greatly in diseases. A. Nephritis.-The kidney always shows the most marked reduction although the other tissues examined, blood, lung, liver, spleen, likewise show decrease in their power of decomposing hydrogen peroxide. This reduction varies directly with the severity of the pathological lesion in the kidney and the clinical symptoms. The urine also in cases of nephritis shows a much greater inhibiting power than normal urine. This may be accounted for by the reaction of the urine, and subsequent work must prove whether or not the kidney takes any more active part in nephritis and secretes into the blood and urine a substance which manifests itself by a reduction in the catalytic activity. B. The catalytic activity of the blood in the two cases of eclampsia which we have studied was not reduced. This is the most important fact we have so far obtained, if it can be substantiated, since it can furnish us with a ready ante-mortem means of differentiating eclampsia and nephritis. C.Pneumonia.-The lung in the stage of red hepatization has an increased catalytic activity. This increase varies directly with the number of intact red blood cells in the exudate, and in the engorged capillaries. Strength is given to this conclusion by the fact, that on the one hand, there is no increased activity in gray hepatization, while on the other hand, there is an enormously increased activity in the fresh hemorrhagic infarct. D. Tuberculosis.-The decreased activity of the lung in tuberculosis is probably due, for the most part, to the lack of blood in the diseased area, while the lowered activity which is present in the other organs is to be explained by the anaemia and emaciation which accompanies the process. Whether there is a specific catalytic inhibiting substance generated by the process, has not been determined. E. There was no reduction of the catalytic activity in the cases of diabetes mellitus and jaundice studied. F. In the one case of asphyxiation by illuminating gas, there was decided decrease in the catalytic activity of the blood. G. The tissues in the one case of congenital syphilis showed a marked lowering of the catalytic activity. 3. There is a slight decrease in the catalytic activity of the tissues due to post-mortem change, but this is so slight that it is hardly to be taken into consideration in the interpretation of the results obtained. 4. There is no marked change in the catalytic activity due to age. In concluding, we wish to thank Dr. A. S. Loevenhart, at whose suggestion this enzyme was studied, for the unfailing interest with which he has followed the progress of this work, and for the many valuable suggestions he has given us.

1. The injurious effects of excessive carbohydrate diet are demon strable in partially depancreatized dogs, in the same manner as in human patients. With severe diabetes there is rapid progress of emaciation and weakness and early death. 2. With milder diabetes, there is frequently a transitional state following operation, when the fate depends on the diet. If the tolerance is spared for a time, recovery sometimes occurs to such extent that diabetes cannot be produced by any kind or quantity of feeding, but only by removal of a small additional fragment of pancreatic tissue. The proper degree of carbohydrate overfeeding is important in this early period for producing the most useful type of diabetic animals; namely, those having good digestion and general health combined with a permanent lowering of assimilative power, like the condition of human patients. 3. In the early stage, glucose is more powerful than starch in producing diabetes, and animals which are progressing toward complete recovery on starch diet can be sent into hopeless diabetes by admix ture of glucose. The difference seems to be merely of the rate of absorption, and indicates that a rapid flood of carbohydrate is more injurious to the pancreatic function than a slow absorption. When ever permanent diabetes is present, so that complete recovery is impossible, starch brings on glycosuria more slowly than sugar, but just as surely. The difference in time in different cases amounts to days, weeks, or months. The clinical lesson from such experiments is that even if a patient becomes free from glycosuria on withdrawal of sugar only, nevertheless other foods should also be limited. 4. No significant differences were observed between the assimilation of different starches, or any extreme lowering of the carbohydrate tolerance by proteins, such as alleged by certain writers in connection with the "oatmeal cure." 5. Repair of traumatic inflammation and hypertrophy of the pancreas remnant have been mentioned incidentally as the basis of the early tendency to recovery, and also hydropic degeneration of Lang erhans islands as an accompaniment of the lowering of tolerance by excessive diet. These are believed to have their parallels in human cases, and are to be described more fully hereafter.
