Extensive water, sodium, chloride, bicarbonate, and potassium losses occur in the diarrheal calf. The water loss is entirely from the extracellular space. In severe cases, hypovolemic shock occurs with the blood volume decreased by as much as one-half. Acidosis, which results from fecal bicarbonate loss, lactic acidosis, and renal dysfunction, results in tissue buffering, which in turn causes the efflux of cellular potassium ions. Although there is a total body potassium deficit, plasma potassium concentration is increased. This, in conjunction with an intracellular deficit, causes weakness,
lethargy
, and potassium cardiotoxicosis resulting in death. Hypoglycemia also contributes to the weakness and
lethargy
seem as calves become moribund. These losses from the body and shifts in fluids and electrolytes must be understood to develop the most effective rationale for supportive therapy.

Fischer 344 rats and B6C3F1 mice were fed diets that contained 0.03, 0.06, 0.1 and 0.2% 4,4'-oxydianiline for 13 weeks. The 0.1 to 0.2% diet caused 40 to 70% mortality in female rats. Although mice ate about 3.5 times more chemical than rats, no mice died. Alopecia, dyspnea and cyanosis in rats, and
lethargy
in both species occurred in the 0.1 to 0.2% groups. Goiter was found in rats that died as early as the 4th to 5th week of study in the groups given the 0.06 to 0.1% diet. At the end of the study, diffuse parenchymatous goiter was seen in all rats given the 0.06% and higher concentration diets and in most mice given the 0.2% diet. In rats, the thyroids also were heavily encapsulated and had interstitial fibrosis and vascular degeneration. There was concomitant hyperplasia of pituitary basophils in both species, but an increase of cells that secrete thyrotropin was seen in rats only.

During the summer and fall of 1973, a few horses, goats, and cattle in the Napa Valley of California became intoxicated by bromide via the ingestion of volunteer oat hay that had been cut from a field treated with methyl bromide, a soil fumigant. The bromide content of the hay ranged from 6,00 to 8,400 ppm. Signs of intoxication were
lethargy
, weakness, and ataxia. Animals experimentally fed the contaminated hay developed signs of intoxication between the 7th and 9th days.

As a causative factor in spontaneous subarachnoid hemorrhage, vascular anomalies, especially aneurysm or arteriovenous malformation, have been generally recognized. On the other hand, subarachnoid hemorrhage from brain tumor and cryptic vascular malformation are rare. We experienced two cases showing subarachnoid hemorrhage from angioblastic meningioma and vascular hamartoma as an initial symptom. Case 1: A 48-year-old woman, who complained of severe headache and vomiting on Feb. 10th, 1972, gradually became
lethargic
. Lumbar puncture revealed moderately hemorrhagic C.S.F.. On the fifth day after the onset, she was admitted to our hospital. On admission she showed disorientation and disturbance of resent memory. Aphasia and agnosia were slightly observed. On ophthalmologic examination right homonymous lower quadrant hemianopsia was observed. The carotid angiogram showed slight square shift of the anterior cerebral artery to the right side, elevation of the middle serebral artery and a homogeneous tumor stain in the occipital region in capillary phase. A walnut sized tumor invading the middle portion of the left lateral sinus and showing firm adhesion to the tentrium was found. There was an intracerebral hematoma behined the tumor. The tumor, the tentrium and the lateral sinus were extirpated en bloc and the intracerebral hematoma was aspirated. Histologically, the tumor was angioblastic meningioma. Case 2: A 7-year-old boy, who complained of severe abrupt headache, nuchal pain and vomiting on Sept. 17th, 1972, became gradually
lethargic
. Lumbar puncture revealed hemorrhagic C.S.F., On the tenth day after the onset, he was admitted to our hospital. He showed confusion and agitation. The carotid angiogram showed an unrolling of the pericallosal artery, but no findings of space taking lesions. An air study indicated a globular filling defect protruding into the anterior horn of the right lateral ventricle. The tumor located in the laterobasal wall of the anterior horn was removed picemiel by transventricular approach. Histologically, the tumor was vascular hamartoma. Furthermore, we discussed various brain tumors showing subarachnoid hemorrhage as an initial symptom, its frequency and bleeding mechanism on the literature.

Within three experiments with broiler-type crossbred chickens, diphenlyhydantoin (DPH) was administered via the diet at levels ranging from 10 to 2500 mg./kg. Feed intake and body weight gain were adversely affected by levels of 100 mg./kg. or higher. A hemorrhagic syndrome occurred in 16 percent of the chickens fed 100-1000 mg./kg. and 33 percent of those fed 2500 mg./kg. Twenty percent of the chickens fed 1000 mg./kg. were anemic; none of those receiving 250 mg./kg. were anemic. Other toxic manifestations included neurological side effects of a
lethargic
stupor, excitability to a disturbance, or a characteristic condition referred to as "head under." Pair-feeding experiments revealed thatlowered feed intake was not responsible for any of the clinical signs. All of the toxicity signs were reversible in 3 to 4 weeks following withdrawal of DPH. Muscle samples contained 2.5 to 11.4 mcg. DPH/g. at drug levels of 1000 and 2500 mg. DPH/kg. diet. Dose-response curves revealed that plasma, adipose, kidney and liver had levels which were, respectively, 1.05, 1.51, 2.19, and 2.85 times those of muscle.

Three years after radiation therapy for an intrasellar tumor, a 42-year-old housewife presented with headache,
lethargy
, and remarkable plain skull roentgenograms, in which dilated lateral and third ventricles were filled with air. Air apparently had entered the cranium through the sphenoid sinus and eroded sellar floor, extending directly through intrasellar remnants of the chromophobe adenoma and into the floor of the third ventricle. Frontal exploration showed an empty sella turcica and no residual tumor. She made an excellent recovery and has done well for 5 years after operative closure of the defect.

Plasma ammonia level (PAL) was studied in 43 cases of acute leukemia (AL). PAL was 39.21 +/- 26.2 mumol/L in normal controls and 38.8 +/- 16.6 mumol/L in leukemic patients before chemotherapy. High PAL was found in 40 cases after chemotherapy. Six cases showed clinical manifestations due to severe hyperammonemia, including dizziness,
lethargy
, confusion, coma and mental changes of various degree, and there was also respiratory alkalosis. After ammonia-trapping therapy, 4 of the 5 patients recovered. The authors believe that high PAL is not uncommon after chemotherapy in leukemic patients. Respiratory alkalosis and unexplained mental and neurologic changes following intensive chemotherapy are useful clues for the diagnosis of hyperammonemia syndrome. Early diagnosis and treatment with ammonia-trapping may improve the rates of remission and survival.

A 43-year-old man who presented parkinsonism due to pontine and extrapontine myelinolysis was reported. Late in February, 1990, the patient presented suffered from a flu-like illness and was seen at a community hospital. Physical finding showed the pigmentation on the whole body and hypotension, and laboratory examination revealed severe electrolyte imbalance (serum sodium 100 mEq/l, serum potassium 6.9 mEq/l, serum chloride 68 mEq/l) and hypoglycemia (postprandial serum glucose 78 mg/dl). Given these results, adrenal failure was strongly suspected. Prompt correction of electrocyte imbalance was performed by the infusion of sodium chloride, and four days later the serum sodium level reached 131 mEq/l. On the other hand, the patient was noticed
lethargic
and showed parkinsonism i.e., rest tremor, cog-wheel rigidity, and hypokinesia. Fourteen days after the onset of neurological abnormalities, the patient was referred to our hospital for further evaluation of parkinsonism. Additionally, neurological examination revealed dysphagia, mutism and positive pyramidal tract sign. On admission brain computed tomography was unremarkable, but on the 14th hospital day it showed low density area in the pons. Brain magnetic resonance imaging also showed a striking increase in T2-weighted signal from the pons, the midbrain, and the bilateral thalamus. Based on these findings, a diagnosis of parkinsonism due to pontine and extrapontine myelinolysis was made, and levodopa therapy was started. After the initiation of levodopa therapy, improvement of tremor, rigidity, and hypokinesia ensued with marked functional benefit, and the patient was discharged on the 49th hospital day. Levodopa was stopped three weeks after discharge but, all neurological abnormalities were not recurrent.(ABSTRACT TRUNCATED AT 250 WORDS)

Splenic and hepatic ultrasonography were beneficial for diagnosis of lymphosarcoma in 3 horses with anorexia, weight loss, and
lethargy
. Ultrasonographic abnormalities of the spleen included a large, complex, hypoechoic mass in 1 horse, multiple well-marginated, hypoechoic nodules in 1 horse, and diffuse hyperechogenicity in another horse. Ultrasonographic abnormalities of the liver included a spherical, hypoechoic nodule in 1 horse and diffuse hyperechogenicity in another. Histologic examination of ultrasound-guided biopsy specimens or aspirates revealed lymphosarcoma. Necropsy findings confirmed diagnosis of lymphosarcoma in all horses. Necropsy findings of the liver and spleen correlated well with antemortem ultrasonographic images.

A 10-year-old Tennessee Walking Horse gelding was admitted to the veterinary teaching hospital for evaluation of intermittent fever,
lethargy
, and anorexia. Initial laboratory analyses revealed anemia and hyperfibrinogenemia. Abdominocentesis and thoracentesis yielded fluid samples with high nucleated cell counts and total protein concentrations. The tentative diagnosis was nonseptic peritonitis. The horse did not improve after 4 days of antimicrobial treatment, and pitting edema of the ventral midline developed. Thoracic radiography and ultrasonography revealed consolidation of the ventral aspect of the lung fields and pleural effusion. Pleuroscopy of the right hemithorax revealed pleural effusion and a soft-tissue mass in the caudal portion of the mediastinum. Findings on biopsy of the liver and mediastinal mass led to a presumptive diagnosis of metastatic cholangiocellular carcinoma. The horse was euthanatized, and the diagnosis was confirmed at necropsy.
