Dose-response relationship among blood cadmium concentrations, catalase and superoxide dismutase activities were studied with acutely intoxicated rats by cadmium. The Sprague-Dawley male rats to which single dose of 1-32 mg/kg CdCl2 were administered into peritoneal cavity were sacrificed by decapitation at 3-36 hours after the administration. Cadmium concentrations in blood increased significantly with dose of CdCl2 administered and reached peak level at 3 hours later. Catalase activities in rats' tests were not correlated with exposure time elapsed after the administration in rats to which 1-2 mg/kg of CdCl2 were administered, but they showed linear relationship with time in groups to which 4-32 mg/kg of CdCl2 were administered. Cu, Zn-SOD activities in tests of acutely intoxicated rats by cadmium were not altered either by dosage or by time elapsed after the administration. Mn-SOD activities in the tests were also not influenced by dosage of 1-2 mg/kg CdCl2, but remarkably inactivated by dosage of 4-32 mg/kg CdCl2 with time elapsed after the administration. Neither catalase, Cu, Zn-SOD nor Mn-SOD activities of tests were correlated with blood cadmium concentrations in acutely intoxicated rats by cadmium.

Aneurysms of the superior mesenteric artery are rare, accounting for 8% of visceral artery aneurysms. About 60% of all superior mesenteric artery aneurysms have a mycotic origin. The only helpful clinical manifestations are episodes of previous abdominal pain and a history of valvular heart disease. In this case, a 66-year-old female patient with mitral regurgitation and aortic regurgitation presented with pain in the upper abdominal area. A superior mesenteric artery aneurysm was diagnosed at the time of impending rupture. Since excellent collateral circulation was present, an aneurysmectomy without revascularization was performed, and no ischemic symptom occurred. The patient presented no major complications during the postoperative course.

3.Study on the Precision in Determinations of Lead and Zinc in the Whole Blood.
Korean Journal of Preventive Medicine 1986;19(1):76-84
Analyses of lead and zinc were made by means of standard addition method using atomic absorption spectrophotometer(Baird Ltd., Model A5100) with flameless method for lead and flame method for zinc. The blood samples used were merely diluted with triton x-100, because it was simple, rapid and minimal risk of contamination. Mean recovery rate for lead added to the blood ranged from 97.7 to 101.3% with coefficient of variation ranging from 1.9 to 10.7%, and that for the added zinc ranged from 99.0 to 102.2% with coefficient of variation ranging from 2.1 to 9.1%. In repeated measurements of zinc in the blood, good reproducibility and inter-individual variation were proved(p<0.01). In comparison of the lead and zinc concentrations in the blood determined by the standard addition method and standard method, there were good correlations between 2 sets of data (r=0.9731 for lead and r=0.9785 for zinc), although lead levels were estimated higher by the former method(p<0.01) and zinc levels by the latter method(p<0.01). It can be concluded that lead zinc levels in blood standard addition method is reliable for determination of lead and zinc in the blood with good accuracy and reproducibility.

The coexistence of the variants of porokeratosis is very rare. We report a case of coexistence of linear porokeratosis with disseminated superficial actinic porokeratosis (DSAP). A 43-year-old wornan first noticed a brownish papule on the left side of groin in early infancy. She developed multiple discrete or confluent keratotic plaques in linear fashion on the left lower extrernity and trunk in childhood. These leaions became pruritic in summer. Two years ago, she developed multiple scattered small annular lesions on the face and forearms. Her family history showed no abnormalities. Biopsy specimene from the groin and trunk showed eornoid lamella.

OBJECTIVES: The purpose of this study was to find the protective effects of garlic on the halogenated hydrocarbon induced hepatotoxicities, and the possible protection mechanisms involved. METHODS: Male Sprague-Dawley rats received garlic (0.5 %) or regular diet, for 4 weeks. This was followed by a single dose of corn oil (the controls), carbon tetrachloride (400mg/kg body weight) and trichloroethylene (2,000mg/kg body weight) being administered to each diet group. Blood samples were collected 24 hours following the administration, and the serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities measured. The liver samples were studied for their cytochrome P450 and CYP2E1 contents, lipid peroxidation and histopathology. RESULTS: The results for the group receiving the 0.5 % garlic diet showed a slight decrease of CYP2E1 expression compared with the regular diet group. Carbon tetrachloride was significantly decreased the CYP2E1 contents in both the regular and garlic diet groups, but the trichloroethylene remained unchanged. Garlic did not decrease the lipid peroxidation of the liver in the control group, but attenuated the increase of lipid peroxidation caused by carbon tetrachloride. Garlic attenuated the increase of both the serum AST and ALT activities caused by carbon tetrachloride. The histopathological observations also showed that garlic attenuated centrilobular necrosis and vacuolar degenerative changes significantly in the carbon tetrachloride treated group. Conclusions : The results indicate that garlic attenuates the carbon tetrachloride-induced hepatotoxicity, through the prevention of the metabolic activation and lipid peroxidation.

Thirty five male Sprague-Dawley rats were treated with cadmium chloride solution ranging from 0.2 to 3.2mg CdCl2/kg by intravenous single injection. At 48 hours after administration of cadmium, total cadmium, MT bound cadmium and histopathologic finding in liver, kidney, lung, heart, testis, metallothionein in liver, kidney and total cadmium in blood were examined. Tissue cadmium concentration was highest in liver, followed by in kidney, heart, lung and testis. Cadmium bound to metallothionein(MT-Cd) and ratio of MT-Cd to total cadmium were increased in liver and kidney dependently of cadmium exposure dose, but not significantly changed in other organs. On histopathologic finding, the most susceptible organ was heart in considering cadmium exposed dose, but testis in considering cadmium concentration. Blood cadmium concentration was increased with dose-dependent pattern, and significantly correlated with tissue cadmium concentration, so that we may estimate tissue cadmium concentration by measurement of blood cadmium concentration. Metallothionein in liver and kidney was increased with dose-dependent pattern, higher in liver than in kidney, and was significantly correlated with tissue cadmium concentration. However, metallothionein induction efficiency of tissue cadmium(microgram MT/microgram Cd) was greater in liver than in kidney, and reverse to tissue concentration or exposed dose of cadmium.

10.Heavy Metal Poisoning.
Hanyang Medical Reviews 2010;30(4):319-325
Heavy metals are distributed in the environment ubiquitously. Metals are widely used in various industries, because of which have characteristics of marked malleability and ductility. Workers are exposed to metals through inhalation in industry, while the general population who has not been exposed to metals occupationally, exposed orally through diet and drinking water. Workers are exposed to the low level of metals chronically. All metals and metal compounds are potentially toxic to human, but many metals are essential and homeostasis is key to survival. Recently, the proportion of heavy metal poisoning is about 1% in the occupational disease, and reported cases annually are around 10 peoples in Korea. Ninety four cases of heavy metal poisoning were reported from 2001 to 2008 in Korea. The most cause of poisoning was chromium of 51 cases, and followed by lead (25 cases), manganese (9 cases), cadmium (6 cases), and mercury (3 cases), in orders. In this paper, there are reviewed and discussed about exposure source and route, absorption and metabolism, health effects, medical treatment and management of major metals mentioned above. Several metals are known human carcinogens, therefore workers exposed to metals in workplace should be controlled with meticulous care. In conclusion, the efficient controls for workers, who are working under the metal contaminated environment in industry, could be suggested as the prohibition of excessive exposure to metals through health education and environmental controls, and prevention and early detection of metal poisoning by the periodic health examination and exposure assessment.
