This study was carried out to clarify the effect of dietary calcium, casein, and suet on the accumulation of cadmium in mice. It was performed for 30 days, from April 11 to May 10 1988. 90 mice were divided into 4 experimental groups and control group with 6 mice each dietary group, and measured survival rate, body weight, and weight ratio of organ to body. The contents of cadmium in liver, kidney, spleen, muscle and skin with hair, and faces were analyzed by atomic absorption spectrophotometer after sacrifice by anesthesia. After 30 days, the survival rate of control group was 100%, but 66.7% in group IV(basal+Cd+Ca) with single dose of 100 microgram cadmium and with free-intake of water containing 50ppm cadmium, and group V(basal diet+Cd+suet) with free-intake of water containing 50ppm cadmium. The rate of weight gain in the case of single dose of 100 microgram cadmium was highest in group IV as 42.3% and lowest in group V as 26.0%, whereas in the cases of free intake group IV was highest as 24.0% and group II(basal diet+Cd) was lowest as 11.6%. The body weight, in the case of single dose of 100 microgram cadmium showed no increase until 5th day after acute poisoning. But in the case of free intake group, it showed very increase through all the breeding period. The weight ratio of organ to body were lowest in the liver of group II in both occasions. The most of cadmium administered were excreted through feces within 2 days after single dose of 100 microgram cadmium. The contents of cadmium in each group were significantly higher than those of control group. In the liver, kidney, spleen and muscle, group II showed the highest level in both occasions of 100 microgram single dose and free intake of water containing 50ppm cadmium. In the skin with hair, group II of the occasion with single dose of 100 microgram and group V with free intake showed the highest level. And the contents of cadmium in tissue were markedly higher in the occasion of free intake of water containing 50ppm cadmium. From the above results I would conclude that the addition of casein and calcium are effective in the inhibition of intension absorption of cadmium esp. by calcium.

Fulminant hepatic failure (FHF) is often accompanied by a myriad of neurologic complications, which are associated with high morbidity and mortality. Although appropriate neuromonitoring is recommended for early diagnosis and to minimize secondary brain injury, individuals with FHF usually have a high chance of coagulopathy, which limits the ability to use invasive neuromonitoring. Jugular bulb venous oxygen saturation (JvO₂) monitoring is well known as a surrogate direct measures of global brain oxygen use. We report the case of a patient with increased intracranial pressure due to FHF, in which JvO₂ was used for appropriate brain oxygen monitoring.

Dieulafoy's vascular malformation is a rare cause of massive gastrointestinal bleeding. Most often it occurs in stomach within 6 cm from the gastroesophageal junction. Only a few cases have been reported to occur in the small intestine and colon. Occasionally, Dieulafoy's lesion of small intestine is difficult to recognize because of rarity, a paucity of symptoms and negative findings on barium studies. Therefore, this lesion needs to be considered in a patient with massive lower gastrointestinal bleeding. We report a case of Dieulafoy's vascular malformation in ileum 2 m proximal to ileocecal value in a 41-year-old woman who visited emergency clinic because of hematemesis, dizziness and vomiting. Small intestine revealed a wide-caliber artery within the submucosa showing intimal thickening, medial muscular hypertrophy and thrombosis.

BACKGROUND: Tetracaine has been the most commonly used long-acting spinal anesthetic agent. Recently, hyperbaric bupivacaine was introduced to be useful agent, and has been reported to produce the better quality of anesthesia. The aim of the present investigation was to compare the anesthetic effects of 0.5% hyperbaric bupivacaine and 0.5% hyperbaric tetracaine spinal anesthesia. METHODS: 40 ASA Class I patients undergoing lower extremity operation were randomly distributed to two groups. Group A (n=20) received 15mg, 0.5% bupivacaine in 8% glucose, while Group B (n=20) received 15mg, 0.5% tetracaine in 10% glucose in the lateral decubitus position (L3,4 interspace). We evaluated the sensory and motor blockade, cardiovascular effects and the incidence of tourniquet pain. RESULTS: The mean maximum cephalad spread of analgesia was higher in bupivacaine group (T5) than in tetracaine group (T6) and the spread time was more rapid in bupivacaine group (13.1 +/- 3.3min.) than in tetracaine group (15.8 +/- 4.3min.), but there were no statistical significances. Tetracaine group was earlier onset of motor block and the duration of complete motor block in tetracaine group was significantly longer than in bupivacaine group. The mean decrease in systolic and diastolic blood pressure was 10% to 25% in both groups and more marked in tetracaine group. The incidence of tourniquet pain was greater in tetracaine group than in bupivacaine group. CONCLUSIONS: The quality of anesthesia obtained with bupivacaine may be superior to that produced by tetracaine. We concluded that 0.5% hyperbaric bupivacaine was suitable for short orthopedic or lower abdominal surgery because of less incidence of hypotension, shorter duration of motor block and lower incidence of tourniquet pain.
