Abstract
A validation of small-dose insulin infusion therapy was studied by the constant i.v. infusion of various doses of insulin into ketoacidotic depancreatized dogs. Constant insulin infusion of 5 x B, 10 X B, 30 X B and 50 X B (B = 225 microunit/kg/min) was performed for 3 h by mechanical pump. The following results were obtained: (1) plasma concentrations of immunoreactive insulin (IRI) increased proportionally to the dose of infused insulin, but the higher IRI did not result in a greater fall in plasma glucose concentration, correspondingly; the mean rate of fall in plasma glucose concentration of 5 x B was not significantly lower than that of 50 x B; beta-hydroxybutyrate and arterial pH improvements were observed in each group during the 3-h insulin infusion. These data suggested that for the improvement of diabetic ketoacidosis, the insulin infusion rate of more than 30 x B, which raised the plasma IRI levels above the physiological range, was not essential; (2) the necessity of potassium supplementation during the small-dose insulin infusion was suggested if the pre-treatment level of serum potassium was low. These results confirmed that in the absence of infection or severe acidosis small-dose insulin infusion therapy is as effective as the conventional large-dose insulin therapy.

Abstract
Water-in-oil-in-water (W/O/W) insulin micelles were prepared, and the possibility of insulin absorption in a micellar form was examined. In this preparation, insulin was trapped in oil droplets of oleic acid in glyceryl-alpha-monooleate. (1) W/O/W insulin micelles were absorbed from the ligated jejunal loop of rabbits to the order of 12.3 to 58.5% of the dose given (10 mU/kg body weight) during the 3-h experimental period. (2) Alloxan diabetic rats were treated with intrajejunal administration of W/O/W insulin micelles at a dosage of either 25 or 50 mU/100 g body weight, three times daily for as long as 14 days. During treatment, a significant reduction in the daily excretion of urinary glucose was observed, concomitant with a decrease in fasting blood glucose. Quantitative estimates suggested that the effectiveness of 25 mU/100 g of intrajejunal W/O/W insulin micelles was comparable to that of regular insulin at a dosage of 1 mU/100 g i.m. These results would indicate that W/O/W insulin micelles, when given enterally, are more effective in lowering blood and urinary glucose levels than W/O/W insulin emulsions in which insulin was trapped in oil droplets of triglyceride.

Abstract
ABSTRACT
The dynamic property of glucose-induced insulin secretion was simulated with the aid of a control theory, and the relationship between the stepwise input of glucose concentration and the biphasic response of insulin as an output was expressed in the transfer function of proportional plus derivative action to glucose concentration. By utilizing this model, the following computer algorithm for the artificial beta cell was made; rate of insulin infusion = Kp BG + Kd ΔBG+ Kc, where BG was the abbreviation for glucose concentration, ΔBG was the rate of change in BG, Kp and Kd were the coefficient for the proportional and derivative action, respectively, and Kc the constant for basal insulin secretion.
Microcomputer, insulin pump and digital printer were packed in small case, which was connected with glucose analyzer.
Experiments were carried out in the depancreatized dogs to validate the importance of infused insulin based on derivative action to glucose concentration in glucose regulation. Kd/Kp ratio was changed when insulin was infused following iv glucose bolus injection. The results revealed that when the derivative action was added to the proportional action properly in insulin infusion regulatory system, insulin requirement was the smallest and glucose regulation was the best.
The characteristics of the system recognized in clinical application were 1) rate of insulin infusion was small enough to keep the plasma concentration of insulin at a physiological level, then insulin requirements were reduced to around a half of those given subcutaneously, 2) glucose or glucagon to restore hypoglycaemia was not essential.

Abstract
Induction of ornithine decarboxylase [EC 4.1.1.17] (ODC) in mouse L cells by components of the culture medium was investigated. It was found that further addition of amino acid mixture, but not of calf serum, to confluent cells of 5 day culture induced ODC and that this induction was accelerated by actinactinomycin D. In salt solution, addition of either amino acids or serum alone did not cause full induction, but addition of both together did. This induction, in contrast, was inhibited by actinomycin D. Induction by insulin, but not by cyclic AMP, was enhanced by a higher concentration of amino acids. These results can be explained by supposing that in non-growing cells there is stable RNA which is involved in ODC induction, possibly mRNA of ODC, and that the observed induction is caused by inhibition of enzyme degradation and accelerated translation, while in growing cells this RNA is unstable and ODC induction is controlled at the level of transcription.

Abstract
The activity of ornithine decarboxylase [EC 4.1.1.17] (ODC) in mouse L cells in the confluent state was induced within 4 hr by cyclic AMP (cAMP) or by insulin. During growth of L cells the concentration of cAMP increased first, then induction of ODC occurred and finally the cell number increased: the levels of cAMP and ODC increased only transitorily and returned to the basal levels when the cells become confluent. In growing cultures, however, the presence of cAMP reduced induction of ODC and cell growth. These results suggest that cAMP is involved in induction of ODC and that its concentration may be important for enzyme induction as well as for cell growth. Actinomycin D with or without these inducers stimulated induction of ODC in L cells, whereas cycloheximide inhibited it, suggesting that these hormones affect the translational level of ODC synthesis. The effect of actinomycin D on induction of ODC was much greater in non-growing cells than in growing cells. It was also found that the half life of ODC was 81 min in non-growing cells and 112 min in growing cells. This suggests that turnover of the enzyme is more rapid in the non-growing than in the growing state and that there may be an RNA fraction which controls its turnover and which also has a very short half life.

Abstract
Ultrastructural localization of the in vitro binding sites of circulating anti-basement membrane zone antibodies was investigated using two immunoperoxidase methods: the ordinary IgG indirect immunoperoxidase method and the complement immunoperoxidase method. The results indicate that the binding sites of the circulating autoantibodies were diverse. It is postulated that those antibodies demonstrable by the ordinary IgG indirect method and those antibodies possessing capacity to fix complement should bind to different sites of the basement membrane zone. Conventional electron microscopic observation of one lesional skin from bullous pemphigoid confirmed this possibility. (Received December 23, 1982.)
