[A case of thyroid storm associated with diabetic ketoacidosis (author's transl)]

A 31-year-old female was well until few years ago when she was diagnosed as having Graves' disease. Methimazole (MMI) and Lugol's solution were prescribed. But 7 months later, she stopped taking them arbitrarily. Three months later, thirst and general fatigue appeared. Therefore insulin (60u/day) and MMI (30 mg/day) were administered and continued for 40 days. However no remarkable effect was brought about. She was then transferred to the radioisotope ward of Kumamoto Univ. Hospital and was treated with regular insulin only. Ten days later, she fell into thyroid storm associated with diabetic ketoacidosis and was transferred to our ward. We began to administer large volumes of transfusion, regular insulin, MMI, Lugol's solution, propranolol, hydrocortisone and digitalis. In 24 hours, ketoacidosis disappeared and she became alert. For hyperthyroidism, the dosage of MMI was increased to 60 approximately 45 mg/day and was continued for a month; however, her thyroid function did not normalize and agranulocytosis developed. MMI was discontinued, and she was treated with 131I. About a year later, she became euthyroid. Her diabetes mellitus was difficult to control during the hyperthyroid state but it was under good control with monocomponent lente insulin (36u/day) when the euthyroid state was resumed.

Purification and partial characterization of heat-stable enterotoxin of enterotoxigenic Escherichia coli

Heat-stable enterotoxin was purified from a strain of enterotoxigenic Escherichia coli 53402 A-1 from human intestine. The cells were cultured in Casamino Acids-yeast extract-salts medium, and the purification procedure consisted of protamine sulfate treatment of the culture supernatant, ultrafiltration with an Amicon PM-10 membrane, diethylaminoethyl-cellulose column chromatography, hydroxyapatite column chromatography, Bio-Gel P-10 gel filtration, 90% ethanol extraction, and preparative polyacrylamide gel disc electrophoresis. About 300-fold purification was achieved, with a yield of about 12%. However, the homogeneity of the purified heat-stable enterotoxin was not rigorously demonstrated. The purified heat-stable enterotoxin had an absorption maximum at about 275 nm, and its isoelectric point was about 3.90. The molecular weight of the purified heat-stable enterotoxin was ca. 4,000 by Sephadex G-100 gel filtration. The minimum effective dose of purified heat-stable enterotoxin was about 2.5 ng in the suckling mouse assay. The purified heat-stable enterotoxin gave a positive reaction in not only the suckling mouse assay but also the mouse intestinal loop test and the guinea pig skin permeability test.

Acoustooptic TeO(2) tunable filter using far-off-axis anisotropic Bragg diffraction

Noncollinear acoustooptic tunable filters using TeO(2) crystals are described. An anisotropic Bragg diffraction is studied applying simple design expressions to a tilt type in which an acoustic wave is launched a little off the [110] axis. Tuning property, filter bandwidth, angular aperture, required acoustic power, deflection angle, divergenceless configuration, and rapid spectrum scanning have been discussed. These filter properties have been confirmed with measurements using three kinds of filter devices: a basic type, an acoustically enhanced type, and a large angular aperture type. A 5-A bandwidth at 4000 A was obtained by slow scanning. A 32-A separation at 4000 A was observed by a rapid scanning of 0.5 msec throughout the visible region with an extremely low electric drive power.

Studies on the metabolism of d-limonene (p-mentha-1,8-diene). IV. Isolation and characterization of new metabolites and species differences in metabolism

1. The main route of elimination of d-limonene administered orally was via the urine in animals and man, 75-95% of the administered radioactivity being excreted in the urine during 2-3 days. Faecal excretion accounted for less than 10% of the dose in animals during 2-3 days. 2. In addition to six metabolites, namely p-mentha-1,8-dien-10-ol (M-I), p-menth-1-ene-8,9-diol (M-II), perillic acid (M-III), perillic acid-8,9-diol (M-IV), p-mentha-1,8-dien-10-yl-beta-D-glucopyranosiduronic acid (M-V) and 8-hydroxy-p-meth-1-en-9-yl-beta-D-glucopyranosiduronic acid (M-VI) isolated from rabbit urine previously (Kodama et al., 1974), five new metabolites have been isolated from dog and rat urine, and which were characterized as 2-hydroxy-p-menth-8-en-7-oic acid (M-VII), perillylglycine (M-VIII), perillyl-beta-D-glucopyranosiduronic acid (M-IX), p-mentha-1,8-dien-6-ol (M-X) and probably p-menth-1-ene-6,8,9-triol (M-XI). 3. The major metabolite of d-limonene in the urine was M-IV in rat and rabbit, M-IX in hamster, M-II in dog and M-VI in guinea pig and man.

Metabolism of 1-(3-trifluoromethylphenyl)-3-(2-hydroxyethyl)quinazoline-2,4(1H,3H)-dione (H-88). II. Abosorption, distribution and excretion in rat, mouse, rabbit, monkey and man

1. The maximum concentration radioactivity in blood occurred 2-4 h after oral administration of [14C]H-88 in mouse, rabbit and man. With rat, a maximum concentration was obtained 24 h after administration of the drug at a dose level of 60 mg/kg, but only 4 h at a dose of 6 mg/kg. Unchanged H-88 comprised about 50% of serum radioactivity in rat and mouse during the first few hours, but only a small proportion of the serum radioactivity in rabbit and man. 2. The distribution pattern of the radioactivity in rat given the drug at two dose levels was similar, and this differed slightly from mouse and considerably from rabbit. Autoradiograms in rat and rabbit confirmed the findings from the distribution studies, and the autoradiographic distribution pattern in monkey was similar to that in rabbit. 3. Of the administered radioactivity 25-30% was recovered from bile within 48 h in bile-duct-cannulated rats and rabbits. Excretion of radioactivity in respiratory CO2 was negligible in the rat.

Metabolism of 1-(3-trifluoromethylphenyl)-3-(2-hydroxyethyl) quinazoline-2,4(1H,3H)-dione (H-88). I. Species differences in metabolism

1. Following oral administration of [14C] H-88 to rat, mouse, quinea-pig and hamster, 40-65% and 5-15% of radioactivity was excreted in urine and faeces respectively during 3 or 4 days. In rabbit, monkey and man, more than 80% of radioactivity was excreted in urine during 2 or 3 days, and faecal excretion was negligible. 2. Rabbit, rat or guinea-pig excreted non-labelled H-88 in urine as unchanged H-88 (M-I), 1-(3-trifluoromethylphenyl) quinazoline-2,4(1H,3H)-dione-3-acetic acid (M-II), H-88 glucuronide (M-III) and 1-(3-trifluoromethylphenyl)-3-(2-hydroxyethyl)-6-hydroxyguinazoline-2,4(1H,3H)-dione (M-IV). 3. The carboxylic acid (M-II) was the major metabolite of H-88 in rat, mouse, guinea-pig and hamster urine and faeces, while the major metabolite in urine of rabbit, monkey and man was H-88 glucuronide (M-III). The 6-hydroxy compound (M-IV) was a major metabolite only in guinea-pig.
