The significance of the position of nonflat punch on dividing prcperties of scored tablets was investigated in several tablets prepared from excipients or granules by one side compaction method.For the excipients, lactose, perfiller®and microcrystalline cellulose were used.For the granules, sieved granules in 12-16, 16-32 and 32-48 mesh incorporating either hydroxy propyl cellulose or potato starch as binder was used.Different influence of the position of nonflat punch on dividing strength of scored tablets was observed between the case of excipients and granules.Dividing strength of scored tablets made from excipients was not affected by the position of nonflat punch.But tablets made from granules had a tendency to show high dividing strength when tablets were compressed by nonflat upper punch.Then weight variation of divided tablets showed a tendency to become less when compressed by nonflat upper punch in both tablets made from excipients and granules.It was suggested that the effect of the position of nonflat punch on dividing properties of scored tablets was caused by different pressure lines during tablet compression.

Acute renal failure developed in a 5 year-old girl during the fifth course of high dose methotrexate (MTX) treatment for osteosarcoma. She showed oliguria, and the serum MTX concentration, BUN and Scr were 461 μmoles/1, 50 mg/dl and 2.6 mg/dl, respectively, at 27 hr after infusion.Massive leucovorin calcium rescure, direct hemoperfusion, hemodialysis and plasma exchange therapies were successfully treated and she recovered gradually.Neither toxic bone marrow suppression nor side effect of massive leucovorin calcium appeared.The pharmacokinetic analysis of MTX during the renal failure and the dialysis treatment was investigated.

Vaporization of nitroglycerin (TNG), thermoanalysis (DTA/TG) and X-ray diffractometry (X-RD) for the complex with TNG and β-cyclodextrin (TNG·β-CD) prepared by saturated solution method and kneading method, and TNG dispersed β-CD and lactose powder were evaluated. The stabilities of strip packaged sublingual tablet of TNG·β-CD (β-CD Tab, TNG content 0.3mg) and conventional sublingual tablet (JP Tab, TNG content 0.3mg, vehicle: lactose) were compared under the each storage condition of room temperature, 37°and 50°C. Pulse pressure in anesthetized dogs, and systolic blood pressure and plasma TNG concentration in 10 healthy male volunteers were measured after sublingual administration of β-CD Tab and JP Tab.The results showed that vaporization of TNG from TNG·β-CD was extremely smaller than that from TNG dispersed β-CD and lactose powder. DTA/TG and X-RD curves for TNG·β-CD showed specific patterns differed from dispersed powder. The decrease of TNG content in β-CD Tab was extremely lower than that of JP Tab under strip packaging. It is also ascertained that β-CD Tab has the same bioequivalency as JP Tab.

Quinone derivatives, such as 2, 3-dimethoxy-5-methy1-6-decapreny1-1, 4-benzoquinone (ubidecarenone, coenzyme Q10, CoQ10), 4, 5-dihydro-4, 5-dioxo-1H-pyrrolo [2, 3-f] quinoline-2, 7, 9-tricarboxylic acid (pyrroloquinoline quinone, PQQ) and 6-(10-hydroxydecy1)-2, 3-dimethoxy-5-methy1-1, 4-benzoquinone (idebenone), significantly inhibited rise of acetaldehyde concentration in blood and liver of rats following ethanol ingestion.Acetaldehyde concentrations decreased in vitro with incubation with 1, 4-benzoquinone or PQQ solution at 40°C. Low acetaldehyde concentrations following ethanol ingestion might be due to PQQ-accelerated oxidation of acetaldehyde.

(Received February 17,1988) Ethanolamine oleate injection containing 30% iopamiron 300 (30% IP 300-E0) has been previously prepared for endoscopic sclerotherapy of esophageal varices on X-ray TV monitor. However,the ability of fluoroscopic visualization of this sclerosing agent was slightly insufficient in clinical use.We prepared ethanolamine oleate injection containing 30% iopamiron 370 (30% IP 370-E0),and measured the physical characteristics such as viscosity and osmotic pressure of this agent.The ability of visualization was observed in patients with esophageal varix by X-ray. The viscosity,which was inversely related to the injectability into varices,of 30% IP 370-E0 was relatively low and its osmotic nressure was almost the same as that of normal saline.30 % IP 370-E0 was easily injected into varices.Better fluoroscopic visualization was obtained by intravariceal injection with 30% IP 370-E0 than with 30% IP 300-E0.These results suggest that 30% 1P370-E0 is more useful agent for endoscopic sclerotherapy of esophageal varices.
