The effects of three chelating agents, sodium N-benzyl-D-glucamine dithiocarbamate(NBG-DTC), 2,3-dimercaptopropanol(BAL), and D-penicillamine(D-PEN), on the distribution, excretion, and renal toxicity of inorganic mercury were compared in rats exposed to HgCl2. Rats were injected i.p. with 203HgCl2 (300 micrograms of Hg and 2 microCi of 203Hg/kg) and 30 min or 24 h later they were injected with a chelating agent (a quarter of an LD50). The injection of the chelating agents significantly enhanced the biliary and urinary excretions of mercury. BAL was the most effective for removal of mercury from the body at 30 min after mercury treatment. The extent of enhancing effect of the chelating agents for removal of mercury at 24 h after mercury was in the order NBG-DTC = BAL greater than D-PEN. The injection of BAL at 24 h after mercury treatment caused the redistribution of mercury to the heart and lung. NBG-DTC did not result in the redistribution of mercury to the heart, lung, and brain. Urinary excretion of protein and AST significantly increased 24-48 h after mercury treatment and decreased to the control values 72 h after mercury. The injection of the chelating agents at 30 min after mercury treatment significantly decreased the urinary excretion of protein and AST. In rats pretreated with mercury 24 h earlier, the chelating agents significantly decreased the urinary protein at 48 h after mercury treatment, but did not decrease the urinary AST. The results of this study indicate that the chelating agents are effective in removing mercury from the body, resulting in the protective effect against the mercury-induced renal damage.

Sepsis is still a major cause of the high mortality rate in the intensive care unit. Many studies have been published about the severity of sepsis, but the cause of mortality in sepsis and multiorgan failure is still obscure. This study investigated the effects of caffeic acid phenethyl ester (CAPE) particularly on the inflammatory and related histopathological changes in the lung, liver and kidney in an experimental sepsis model. Forty Sprague Dawley rats were used in this study, and were divided into four groups of ten rats each, as follows: Group I was given intraperitoneal saline infusion treatment. Group II was given intraperitoneal CAPE infusion treatment. Sepsis was induced in the animals in Group III (sepsis with saline infusion), while Group IV rats underwent induced sepsis plus CAPE infusion treatment (sepsis with CAPE infusion). Sampling was performed 48 h after treatment. The induction of sepsis resulted in a significant increase in serum glucose, leukocytes, urea, creatinine, LDH levels in BAL, plasma MDA, AST and ALT levels in the sepsis + saline group. The use of CAPE significantly decreased these parameters. Histopathological examination revealed less congestion, portal inflammation, and focal necrosis of the liver, and less congestion, edema, and emphysematous and inflammatory changes in the lung in the sepsis + CAPE group than in the other groups. These results support that CAPE may be used for the treatment of organ failure during sepsis.

Sarcoidosis is a granulomatous disease of unknown origin, with pulmonary findings in more than 90% of patients. Extrapulmonary involvement is common and all organs can be involved (especially lymph nodes, eyes, joints, central nervous system) but it is rare to find an isolated extrapulmonary disease (less than 10% of patients). Granulomatous inflammation of the spleen and the liver is common in patients with systemic sarcoidosis, while hepatosplenic enlargement is unusual and splenic involvement rare. We report two cases of systemic sarcoidosis, that onset with splenic and hepatosplenic disease, and one case with splenic sarcoidosis without pulmonary involvement. In the first case a 53-year-old woman with mild abdominal pain underwent sonography and CT, which revealed one hypoechoic/hypodense splenic lesion. Laboratory tests were normal. In order to exclude a lymphoma, splenectomy was performed: histology revealed a sarcoid granuloma. After surgery the patient was asymptomatic and now, after two years, disease is silent. The second case is a 66-year-old woman with a recent weight loss (8 kg in two months) and alterated liver function tests (AST 61 U/l, ALT 72 U/l, Alkaline phosphatase 748 U/l, g-GT 381 U/l). Since she had a familiar history of colon cancer, abdominal US scan, abdominal CT scan and MRI were performed and showed inter-aorto-caval lymphadenopathies and discreet multiple bilobar hepatic and splenic substitutive lesions, with no signs of primary tumor. Upper and lower GI endoscopy, full gynecological workup, complete set of tumor markers, bone marrow biopsy were performed. All resulted negative for neoplasia. Small pulmonary infiltrations were observed on chest-CT scan but cytology on BAL was normal. Infections were also excluded. An exploratory laparotomy showed whitish peritoneal, hepatic and splenic nodules. The histological exam revealed chronic granulomatous lesions typical for sarcoidosis. During a two-year follow-up after the splenectomy the patient feels well without any treatment. The third patient is a 32-year-old woman with mild epigastric pain after meals. Neck-thoracic CT, bone scintigraphy and upper GI endoscopy were negative. Abdominal US and MR showed splenomegaly with multiple splenic lesions. Splenectomy was performed and histological exam showed chronic granulomatous lesions typical for sarcoidosis. Further laboratory tests were normal, except for ACE (66 UI/l). After the surgery ACE became normal and now, three years later, the patient is still asymptomatic. We conclude that hepatosplenic involvement is less rare than it is thought. It is often oligosymptomatic or accompanied with unspecific manifestations and laboratory abnormalities. The diagnosis could be difficult; in fact typical laboratory findings of sarcoidosis such as ACE, lysozyme, calcium, were not diagnostic. Ultrasonography and CT were important but the diagnosis was established only with the histological examination of suspected lesions. This latter required to differentiate liver and/or spleen sarcoidosis from tuberculosis and other infections, primary biliary cirrhosis, metastasis or malignant lymphoma.
