Numerous reports of anaphylactoid reaction to d-tubocurarine have appeared since 1936. Also it has been suggested that histamine released as a consequence of clinical doses of d-tubocur arine is not in sufficient quantity to evoke symptoms. We recently had experience with a case who had of severe circulatory collapse and urticarial reaction while being anesthetized with ether and d-tubocurarine. This report draws attention to the risk of administering histamine releasing drugs and references are reviewed.

During ether anesthesia in man, succinylcholine(lmg/kg of body weight) was administered intravenously after pretreatment with 0.2% lidocaine 50-60mg or Inderal(1. 0mg). The effects were as follows: 1) Heart rates were increased during ether anestheaia. 2) Lidocaine produced no effects on heart rates rncreased by ether, but heart rates were decreased following administration of succinylcholine. 3) Inderal decreased heart rates, increased by ether anesthesia. Heart rates were increased following administration of succinylcholine.

A 42-year-old Korean female patient with vitiligo universalis had depigmentation therapy with 20 monobenzyl ether of hydroquinone(MBEH). Noticeable lightening was observed 1 month after depigmentation therapy, three months later, complete depigmentation was achieved. As depigmentation induced by MBEH is generally irreversible, MBEH must be reserved for induction of complete depigmentation in severe cases of vitiligo in which the patients themselves do not want repigmentation and who can aecept the consequences of permanent non-tanning skin.

This experiment was attemptel to observe possible effects of ether, halothane and methoxyflurane on the blood sugar level of the rabbit, 5, 15, 30 and 60 minutes after start of anesthesia with ether halothane and methoxyflurane by a non-rebreathing system. Comparision was made between preanesthetic and postanesthetic levels of blood sugar and the following results were obtained. In the ether anesthesia group, the blood sugar level 15 minutes after anesthesia was increased and decreased gradualley a anesthesia was progressed. In the halothane group, the blood sugar level was increased 5 minutes after anesthesia, and then decreased more rapidly than in other groups. Blood sugar levels 60 minutes after anesthesia had returned to preanesthetic levels in all groups. As the above result shows, blood sugar levels were revealed to have a tendency to increase during induction of anesthesia, and then returned gradually to the preanesthetic level during maintenence of anesthesia.

The effectivenss of intravenous Ritalin (10 mg vs. 20 mg) and nasal instillation of diethyl ether (2 cc) for the treatment of hiccup in 38 patients during and immediately following anesthesia. Ritalin, regardless of the dosage employed, was more effective than ether. Nausea and retching were more prevalent among patients treated with Ritalin, however, than with ether.

The petroleum ether fraction of ethanol extract of Acorus tatarinowii were separated by column chromatography and recrystallization to afford seven compounds. On the spectroscopic analysis, they were identified as 1-hydroxy-7(11),9-guaiadien-8-one (1), calamenone(2), cis-asarone(3), chrysophanol (4), physcion (5), emodin (6), (+)-galbacin (7). Compound 1 is a new compound. Compounds 4-7 were isolated from this plant for the first time.

In an attempt to observe possible effects of ether, halothane and methoxyflurane anesthesia on the protein contents of tracheobronchial washings in rabbits, the animals were subjected to moderate afiestbesia with ether, halotbane and methoxyflurane by a non- rebreathing system for one hour. A comparison was made of the protein contents of tracheobronchial washings and the ,results are summarized as follows; 1) The average protein contents of tracheobronchial washings of normal rabbits was 85. 8 +/-27. 44 umg/ml. 2) Increased protein contents of tracheobronchial washings were observed after ether, halothane and methoxyflurane anesthesia compared with the normal. It is concluded that inhalation anesthesia stimulates secreting glands of the tracheobronchial lumen.

PaO2 and PaCO2 values were studied in 8 surgical patients with a modified Flagg can system anesthesia. Arterial blood gases were analyzed with a Radiometer before every induction, after the first 30 minutes of anesthesia and in the immediate post-anesthetic period. The following results were obtained: 1) The values of PaO2 and PaCO2 in all cases during anesthesia did not show any remarkable change. 2) In cases, with no necessity of muscle relaxation or assisted and controled respiration, especially in children, the modified Flagg can system anesthesia seemed to be safe, simple and economical.

PURPOSE: The purpose of this study was to determine whether in vitro plain radiography and ultrasonography(US) could predict the outcome of gallstone dissolution with methyl tert-butyl ether(MTBE). METHODS AND MATERIALS: The plain radiography and ultrasonography of 75 gallstones removed at surgery from 75 patients were obtained. The plaih radiographic findings were grouped by their calcification pattern as group l:lucent, group 2:central, group 3:diffuse and group 4: laminated. The ultrasonographic findings were grouped by their echo pattern as group 1 :arc shaped, clearly defined surface echo followed by distinct acoustic shadow, group 2:strong surface echo with gradually attenuating, meniscus shaped inner echo, group 3:strong surface echo with fill-in pattern of internal echo, group 4:strong surface echo with irregular inner echo and group 5:entirely discerning circumsference, homogeneous internal echotexture. After imaging, the gallstones underwent MTBE dissolution for 6 hours. The residual weight of each stone was measured every 2 hours. The correlation between imaging findings and dissolution rate was retrospectively analysed. RESULTS: The radiolucent and central calcification stones were dissolved rapidly as compared with the diffuse and laminated calcification stones(p<.05). There was no statistically significant difference among the groups based on ultrasonographic findings alone. However, after exclusion of the certain calcification groups that were resistent to dissolution-diffuse or laminated calcification stones-all US groups except one that shows wholly circumscribed margin and homogeneous fill-in pattern of internal echo dissolved well to average 20% or less of the original weight(p<.05). CONCLUSION: MTBE dissolution can be tried in stones that meet both ultrasonographic (not a stone with homogeneous fill-in pattern of internal echo) and plain radiographic (radiolucent or cental calcification stone) criteria.
