We determined the frequency of thyroid autoantibodies in fibromyalgia (FM) patients and the relationship between FM symptoms and these antibodies. Euthyroid 128 FM patients, 64 rheumatoid arthritis (RA) patients, and 64 healthy control subjects were included in the study. The sociodemographic features and the clinical features of FM patients were determined. By using a visual analog scale, patients were questioned about the severity of FM-related symptoms. All patients were administered with Duke-Anxiety Depression (Duke-AD) scale, the physical function items of the fibromyalgia impact questionnaire scale. Thyroid autoimmunity was defined as the presence of detectable antithyroglobulin (TgAb) and/or antithyroid peroxidase (TPOAb) antibodies by the immunometric methods. Patients with a connective tissue disorder, hypo- or hyperthyroidism, and patients who had psychiatric treatment within the last 6 months were not included into the study. The frequencies of thyroid autoimmunity in FM (34.4%) and RA (29.7%) patients were significantly higher than controls (18.8%) (p<0.05). Twenty-six (20.3%) FM patients had positive TgAb and 31 (24.2%) had positive TPOAb. When patients with thyroid autoimmunity were compared to others, it was seen that the mean age, the percentage of postmenopausal patients, the frequency of dryness of the mouth, and the percentage of patients with a previous psychiatric treatment were higher in this group (p<0.05). FM patients had thyroid autoimmunity similar to the frequency in RA and higher than controls. Age and postmenopausal status seemed to be associated with thyroid autoimmunity in FM patients. The presence of thyroid autoimmunity had no relationship with the depression scores of FM patients.

Cotton plants (Gossypium hirsutum. Linn. var. Sankar 4) were grown at normal and toxic levels of substrate manganese, and the altered metabolism of manganese toxic plants was studied. The tissues of plants exposed to toxic levels of manganese had higher activities of peroxidase and polyphenol oxidase, and the activities of catalase, ascorbic acid oxidase, glutathione oxidase and cytochrome c oxidase were lowered. In addition, the high manganese tissue had lower contents of ATP and glutathione but higher amounts of ascorbic acid. The respiration of the partially expanded leaves and the growing tips of toxic plants were depressed when compared to that of the normal tissues. The metabolic changes of manganese toxicity of cotton are placed in the following order: accumulation of manganese in the leaf tissue; a rise in respiration; stimulation of polyphenol oxidase; the appearance of initial toxicity symptoms; the evolution of ethylene and stimulation of peroxidase; the presence of severe toxicity symptoms; the depression of terminal oxidases and respiration; abscission of the growing tip and proliferation of the stem tissue. The early stimulation of polyphenol oxidase may be used to detect potential manganese toxicity.

A 3-year-old, male, domestic shorthaired cat was presented with a 3-day history of anorexia and depression. The cat was moderately dehydrated, had pale, slightly icteric, mucous membranes, oral ulcerations, and mild hepatosplenomegaly. A feline leukemia virus (FeLV) antigen test was positive. CBC results obtained at initial presentation included severe normocytic, normochromic, nonregenerative anemia, severe thrombocytopenia, and marked leukocytosis (>100,000/microL) with 77% eosinophils. After 15 days of treatment with prednisone and doxycycline, the cat had persistent severe nonregenerative anemia (HCT 3.4%), thrombocytopenia (28,000/microL), and extreme eosinophilia (total eosinophils, 123.1 x 10(3)/microL; segmented 103.0 x 10(3)/microL; immature 20.1 X 10(3)/microL). Cytologic examination of aspirates from bone marrow, liver, lymph nodes, and spleen revealed a predominance of mature and immature eosinophils, many with dysplastic changes. The M:E ratio was 96.4. On histopathologic examination, multiple organs were infiltrated by eosinophilic granulocytes. Neoplastic cells in blood and bone marrow stained positive for alkaline phosphatase and were negative for myeloperoxidase, chloroacetate esterase, and alpha-naphthyl acetate esterase. On flow cytometric analysis of peripheral blood, the neoplastic cells were positive for CD11b and CD14. These findings were consistent with chronic eosinophilic leukemia. To our knowledge, this is the first report of chronic eosinophilic leukemia in a cat associated with naturally acquired FeLV infection, in which flow cytometry was used to characterize the neoplastic cells.

A 71-year-old man was admitted to our hospital because of fever and rapidly progressive renal insufficiency over a month. He had depression and Alzheimer's disease as complications. On admission, his serum creatinine was 5.4 mg/dL, and the serum CRP and MPO-ANCA were 18.2 mg/dL and 285 EU, respectively. A computed tomographic chest scan showed pericardiac effusion and fibrosis in both lower lung fields. Although microscopic polyangiitis(MPA)was inferred from a positive MPO-ANCA, renal biopsy could not be carried out. The initial therapy was started with pulse methylprednisolone therapy, followed by oral administration of prednisolone at the dose of 1 mg/kg(60 mg/day). As a result, his fever and inflammatory findings disappeared, and renal insufficiency was ameliorated with a smooth recovery and the pericardial effusion was markedly diminished. However, on the 18th hospital day, chest radiography revealed a nodular shadow in the right lung. Fungus infection was suspected because his serum beta-D-glucan level was extremely high (above 999 pg/mL). Mikafungin, therefore, was started at a dose of 75 mg/day and then, the dose was increased up to 300 mg/day. Nevertheless, he finally died of respiratory failure on the 26th hospital day. The autopsy findings revealed a cavity of 4.0 x 3.0 x 3.0 centimeters in size in the upper lobe of the right lung. There was a great number of fungal threads with a septal wall branched in a Y-shaped figure around the cavity, thus indicating pulmonary aspergilloma. Intranuclear inclusion bodies staining positive for cytomegalovirus were observed in all the lung fields, suggestive of a cytomegalovirus infection. In the kidney, a cellular crescent formation was noted in the majority of glomeruli showing crescentic glomeluronephritis, compatible with MPA.

Our objectives were to investigate thyroid abnormalities and autoimmunity in 120 patients affected by fibromyalgia (FM) and to study their relationships with clinical data and symptoms. Thyroid assessment by means of antithyroglobulin antibodies, antithyroid peroxidase antibodies, free triiodo-thyronine, free thyroxine, and thyroid stimulating hormone analyses was carried out. The clinical parameters "Fibromyalgia Impact Questionnaire", pain, tender points, fatigue, and other symptoms, and the presence of depression or anxiety disorders were evaluated. The basal thyroid hormone levels of FM patients were in the normal range, while 41% of the patients had at least one thyroid antibody. Patients with thyroid autoimmunity showed a higher percentage of dry eyes, burning, or pain with urination, allodynia, blurred vision, and sore throat. Correlations found between thyroid autoimmunity and age or with the presence of depression or anxiety disorders were not significant. However, in the cohort of post-menopausal patients, the frequency of thyroid autoimmunity was higher with respect to pre-menopausal patients. In conclusion, autoimmune thyroiditis is present in an elevated percentage of FM patients, and it has been associated with the presence of typical symptoms of the disease.

To elucidate the deleterious effects of excess lead on radish (Raphanus sativus) cv. Jaunpuri plants were grown in refined sand in complete nutrient solution for 30 days. On the 31st day lead nitrate was superimposed at 0.1 and 0.5mM to radish for 65 days. A set of plants in complete nutrient solution was maintained as control for the same period without lead. Excess Pb at 0.5mM showed growth depression with interveinal chlorosis on young leaves at apex. Excess Pb reduced the fresh and dry weight pronouncedly at d 65. Lead accumulation reduced the concentration of chlorophyll, iron, sulphur (in tops), Hill reaction activity and catalase activity whereas increased the concentration of phosphorus, sulphur (in roots) and activity of peroxidase, acid phosphatase and ribonuclease in leaves of radish.

There is a gender-related comorbidity of pain-related and inflammatory bowel diseases with psychiatric diseases. Since the impact of experimental gastrointestinal inflammation on the emotional-affective behavior is little known, we examined whether experimental gastritis modifies anxiety, stress coping and circulating corticosterone in male and female Him:OF1 mice. Gastritis was induced by adding iodoacetamide (0.1%) to the drinking water for at least 7 days. Inflammation was assessed by gastric histology and myeloperoxidase activity, circulating corticosterone determined by enzyme immunoassay, anxiety-related behavior evaluated with the elevated plus maze and stress-induced hyperthermia tests, and depression-like behavior estimated with the tail suspension test. Iodoacetamide-induced gastritis was associated with gastric mucosal surface damage and an increase in gastric myeloperoxidase activity, this increase being significantly larger in female mice than in male mice. The rectal temperature of male mice treated with iodoacetamide was enhanced, whereas that of female mice was diminished. The circulating levels of corticosterone were reduced by 65% in female mice treated with iodoacetamide but did not significantly change in male mice. On the behavioral level, iodoacetamide treatment caused a decrease in nocturnal home-cage activity, drinking and feeding. While depression-related behavior remained unaltered following induction of gastritis, behavioral indices of anxiety were significantly enhanced in female but not male mice. There was no correlation between the estrous cycle and anxiety as well as circulating corticosterone. Radiotracer experiments revealed that iodoacetamide did not readily enter the brain, the blood-brain ratio being 20:1. Collectively, these data show that iodoacetamide treatment causes gastritis in a gender-related manner, its severity being significantly greater in female than in male mice. The induction of gastritis in female mice is associated with a reduction of circulating corticosterone and an enforcement of behavioral indices of anxiety. Gastric inflammation thus has a distinct gender-dependent influence on emotional-affective behavior and its neuroendocrine control.

Acceleration of blood leukocyte apoptosis in major depression has been described. The present studies have been undertaken to estimate the level of apoptosis of blood leukocytes in patients with depression and to examine the mechanisms leading to apoptosis. Blood was taken from 29 patients with depression (age 48.2+/-11.2, 14 males, 15 females) and 30 healthy controls (age 41.3+/-4.1, 15 males, 15 females), and apoptosis was estimated by the cytometric method by measurements of annexin V binding, mitochondrial membrane potential (DeltaPsi), bcl-2, bax, and Fas (CD95) expression in CD4+, CD8+ and CD14+ cells. The amounts of cytochrome c released from mitochondria to cytosol of peripheral blood mononuclear cells (PBMCs) and polymorphonuclear cells (PMNs) were also measured. The levels of reactive oxygen species (ROS) released from PMNs were examined as was the serum activity of superoxide dismutase (SOD), catalase (CAT), and total peroxidase (PER). Additionally, serum levels of the tumor necrosis factor (TNF-alpha) and interleukin-6 (IL-6) were estimated. Our experiments indicated accelerated apoptosis of CD4+ T lymphocytes and CD14+ cells (mainly neutrophils) of depressed patients as well as a significant increase in the percent of Fas-expressing cells. Bcl-2 and bax expression was higher in cells of depressed patients than in control, however, bcl-2/bax ratio was significantly decreased in CD14+ cells of depressed patients. PMNs isolated from the blood of the patients produced more ROS spontaneously and after induction with phorbol ester (PMA) than PMNs of the healthy control. A significant increase in serum activity of SOD, CAT and PER was also detected. Overproduction of superoxide anion correlated positively with the level of PMNs apoptosis (measured by cytochrome c release), suggesting that superoxide anion might be an important factor inducing apoptotic death of blood cells. The result of our experiment indicated that apoptosis of immune cells may affect patient's susceptibility to different infections and application of antioxidants in medication of patients with depression will be beneficial for them. The increased level of IL-6 in sera of the depressed patients did not correlate with overproduction of ROS, suggesting that this cytokine is not involved in oxidative stress and apoptosis of leukocytes.

A 2-year-old, spayed female domestic shorthair cat was referred with a history of anorexia and depression of 1 week duration. On physical examination, the cat was lethargic and febrile, with splenomegaly, anisocoria and ulcerative stomatitis. A complete blood count (CBC) and a biochemistry profile showed leukocytosis, numerous blast cells in the peripheral blood, thrombocytopenia, hyperglobulinaemia and a positive test for feline leukaemia virus antigen. A diagnosis of acute myelomonocytic leukaemia was made on the basis of the results of bone marrow cytology, histopathology, and immunochemistry (CD3, CD79a, lysozyme, and myeloperoxidase) tests. Following an unexpected 1-month period of clinical and clinicopathological remission without chemotherapy, the cat relapsed and died 1 week later.

The phytotoxicity and antioxidative adaptations of lead (Pb) accumulating ecotype (AE) and non-accumulating ecotype (NAE) of Sedum alfredii Hance were investigated under different Pb treatments involving 0, 0.02 mmol/L Pb, 0.1 mmol/L Pb and 0.1 mmol/L Pb/0.1 mmol/L ethylenediaminetetraacetic acid (EDTA) for 6 days. With the increasing Pb level, the Pb concentration in the shoots of AE plants enhanced accordingly, and EDTA supply helped 51% of Pb translocation to shoots of AE compared with those treated with 0.1 mmol/L Pb alone. Moreover, the presence of EDTA alleviated Pb phytotoxicity through changes in plant biomass, root morphology and chlorophyll contents. Lead toxicity induced hydrogen peroxide (H2O2) accumulation and lipid peroxidation in both ecotypes of S. alfredii. The activities of superoxide dismutase (SOD), guaiacol peroxidase (G-POD), ascorbate peroxidase, and dehydroascorbate reductase elevated in both leaves and roots of AE as well as in leaves of NAE with the increasing Pb levels, but SOD and G-POD declined in roots of NAE. Enhancement in glutathione reductase activity was only detected in roots of NAE while a depression in catalase activity was recorded in the leaves of NAE. A significant enhancement in glutathione and ascorbic acid (AsA)levels occurred in both ecotypes exposed to Pb and Pb/EDTA treatment compared with the control, however, the differences between these two treatments were insignificant. The dehydroascorbate (DHA) contents in roots of both ecotypes were 1.41 to 11.22-fold higher than those in leaves, whereas the ratios of AsA to DHA (1.38 to 6.84) in leaves altering more to the reduced AsA form were much higher than those in roots. These results suggested that antioxidative enzymes and antioxidants play an important role in counteracting Pb stress in S. alfredii.
