Abstract
An antemortem diagnosis of lymphosarcoma was made in a captive Eastern king snake and a rhinoceros viper. The Eastern king snake died on the 1st day after biopsy of a liver nodule, and necropsy revealed multiple tumor nodules throughout all major organ systems. The rhinoceros viper died after chemotherapy with cytosine arabinoside. The major gross lesion was a large paracolonic coelomic tumor that extended into the adjacent musculature and subcutaneous tissue of the lateral abdominal wall. The immediate cause of death of the rhinoceros viper was believed to be severe renal tubular necrosis.

Abstract
Of 438 snakes in a zoologic collection, 35 died during a 3-month period; all were members of the family Viperidae. Clinical signs consisted of gaping of the mouth followed within 1 day by convulsions. All necropsied animals had a mucoid exudate throughout the respiratory tract. Histologic evaluation of lung revealed evidence of interstitial pneumonia, with occasional eosinophilic intracytoplasmic inclusions in epithelial cells. A paramyxo-like virus, isolated in viper heart cells from lung tissue, was observed by electron microscopy to be budding from cell membranes. The virus hemagglutinated chicken red blood cells at 5 C, and antibody titers were assayed by hemagglutination inhibition. In a random survey of 22 snakes from the zoologic collection, antibody titers to the virus ranged from 1/20 to 1/2,560.

Abstract
During temperature-induced transition of the dimorphic pathogenic fungus Histoplasma capsulatum from the single yeast cell form to the multicellular mycelial form, there was an increase in intracellular cyclic adenosine 3',5'-monophosphate (cAMP) levels as well as a striking accumulation of cAMP in the medium. cAMP levels also changed during the reverse mycelium-to-yeast transition.

Abstract
The 3T3 cells were treated with 50 mu g/ml lysolecithin (LL) followed by the addition of exogenously supplied radiolabelled sugar nucleotides to serve as direct glycosyl donors. These were found to be 1.5 to 3.0 times more active than untreated cells in their glycosyl transferase activities depending on the particular sugar nucleotide used. Mannosyl transferase activity was not inhibited by 2-deoxyglucose or mannose-1-phosphate, indicating that the sugar nucleotide remained intact throughout the assay period. Preincubation of the cells with tunicamycin caused an 85% decrease in mannosyl transfer, which suggested that the normal pathway of glycosylation via lipid intermediates was still operable in the treated cells. Fractionation of control and LL-treated cells after incubation with UDP[3H]galactose revealed that only microsomal and cytosolic proteins from the treated cells were radioactive. Thus, intracellular labelling of permeabilized cells was allowed. About 80% of the radiolabeled product was glycoprotein in nature, based upon its solubilization with pronase.

Abstract
A patient with advanced chronic renal failure secondary to polycystic kidney disease suffered an episode of volume contraction during which his urinary sodium concentration fell to less than 5 mEq daily. Urine sodium excretion remained at this level when later in his course he became clinically volume expanded. The patient also suffered from Crohn's disease and had an ileostomy from which he excreted from 100 to 150 mEq sodium daily. We propose that this patient's capacity to produce urine virtually free of sodium despite advanced renal failure was a result of the persistent loss of sodium from his ileostomy. This sodium loss obviated the development of the adaptive natriuresis that usually occurs in the functioning nephrons of the diseased kidney and prevented the development of a 'salt-losing' tendency.

Abstract
A rock rattlesnake (Crotalus lepidus) with a history of progressive central nervous disease was submitted for necropsy. The histopathologic findings included evidence of interstitial pneumonia, multifocal areas of gliosis in the brain, and ballooning degeneration and demyelination of brainstem and upper spinal cord axons. By electron microscopy, brainstem tissue was found to contain numerous virus particles in the extracellular spaces. A paramyxo-like virus, isolated in viper heart cells from lung tissue, was observed by electron microscopy to be similar in size and shape to the particles seen in nerve tissue.

Abstract
All living and most fossil representatives of the reptilian subclass Archosauria lack pineal bodies. Arrhythmic, low-level, nonpineal melatonin is present, however, in the blood of Alligator mississippiensis. Although pineal bodies have been implicated in circadian phenomena, these results suggest that arrhytmic melatonin in alligators may not be involved incircadian events and indicate that the pineal is not the only source of the hormone melatonin. The evolutionary loss of the pineal in Archosauria occurred during the Mesozoic, and era noted for its seasonal stability. Arrhythmic melatonin titers inalligators and pineal loss in alligators and other archosaurs may be related to Mesozoic seasonal stability.

Abstract
A 21% incidence of false-positive hemagglutination inhibition tests for pregnancy associated with tubo-ovarian abscess is described. Five illustrated cases and the causes for such false-positive reactions are discussed. Substances generated by pelvic inflammatory masses may interfere with immunologic assays for pregnancy, resulting in misdiagnosis or inappropriate management.

Abstract
Organo-sulfur compounds favor the transition of mycelia of Histoplasma capsulatum to the yeast form (6, 8). Investigation of the role of cystine in the transition revealed that the two phases concentrated this amino acid at comparable rates and that mutants defective in the uptake of cystine were still able to undergo the transition normally. Uptake of cystine is therefore probably not a requirement for transition to or maintenance of the yeast phase. Both phases contained a reduced nicotinamide adenine dinucleotide phosphate-dependent glutathione reductase; but a reduced nicotinamide adenine dinucleotide-dependent cystine reductase was detectable only in the yeast phase. The cystine reductase appeared early in the transition of mycelium to yeast. Treatment of mycelia with p-chloromercuriphenylsulfonic acid, which prevented the transition to yeast, had no effect on cystine uptake but strongly inhibited the cystine reductase. These results suggest that cystine reductase may provide reduced sulfhydryl groups involved in the transition of mycelium to yeast.

Abstract
An immature bald eagle (Haliaeetus leucocephalus) was submitted to the University of Maryland, College Park, for clinical examination. The bird was thin, had green watery feces, and was unable to maintain itself in upright posture. Following radiography, the bird went into respiratory distress and died. Numerous lead shot were recovered from the gizzard, and chemical analysis of liver and kidney tissue revealed 22.9 and 11.3 ppm lead, respectively. The clinical signs, necropsy findings, and chemical analysis of the eagle were compatible with lead toxicosis.

Abstract
Pulmonary artery wedge and plasma colloid osmotic pressures and their relationship to pulmonary edema were investigated in 26 patients with acute myocardial infarction of whom 14 developed pulmonary edema. In the absence of pulmonary edema, both the pulmonary artery wedge pressure and plasma colloid osmotic pressure were in normal range; after onset pulmonary edema, a moderate increase in pulmonary wedge pressure and reduction in plasma colloid osmotic pressure were observed. When the gradient between the plasma colloid osmotic pressure and the pulmonary artery wedge pressure was calculated, highly significant differences were demonstrated (P less than 0.002). In the absence of pulmonary edema, this gradient averaged 9.7 (plus or minus 1.7 SEM) torr; following appearance of pulmonary edema, it was reduced to 1.2 (plus or minus 1.3) torr. During therapy with digoxin and furosemide, reversal of pulmonary edema was closely related to a concomitant change in the colloid osmotic-hydrostatic pressure gradient. These observations indicate that both increases in pulmonary capillary pressure and decreases in colloid osmotic pressure may follow the onset of pulmonary edema. Such decline in colloid osmotic pressure and especially the reduction in colloid osmotic-hydrostatic capillary pressure gradient may favor transudation of fluid into the lungs.
